Question of the Month

What is truth, the following answers to this question each win a signed copy of how to be an agnostic by mark vernon. sorry if you’re not here; there were lots of entries..

True beliefs portray the world as it is; false beliefs portray the world as other than it is. A straight ruler appears bent when half-submerged in a glass of water. What is the truth of the matter? Truth’s character is both logical and empirical. The logical ‘principle of non-contradiction’ ensures that the contradictory propositions ‘the ruler is straight’ and ‘the ruler is not straight’ cannot both be true at the same time, and in principle observation should settle which is the case. In practice, things are not so simple. The observable truth would seem to change as the ruler enters the water. Perhaps this is to be expected? After all, if true beliefs describe the world, and the world changes, then truth must change too. However, relativists rubbing their hands at the thought that we each construct our own truth, and sceptics finger-wagging that this shows there is no such thing as truth, should both hold fire. As well as the principle of non-contradiction, we are also guided by the empirical principle that nature is uniform and not capricious. Solid objects are not usually deformed by immersion in water. So, we can approach a truth that is independent of particular observations by, ironically, taking account of the observer in looking at the bigger picture: optical effects resulting from refraction of light explain why the ruler appears bent but, really, is straight.

But how can we be sure there is a world to describe? What if reality itself is an illusion, like the bent stick – a flickering shadow on a cave wall? We may never know whether our observations are just shadows of what is real, but we should resist both mysticism and metaphysics when thinking about truth.

Reaching a consensus on an objective description of the world is possible in principle. That is the wonder of science. Consensus on our subjective descriptions is impossible in principle. That is the wonder of consciousness. Truth is the single currency of the sovereign mind, the knowing subject, and the best thinking – in philosophy, science, art – discriminates between the objective and subjective sides of the coin, and appreciates both the unity of reality and the diversity of experience.

Jon Wainwright, London

Let’s not ask what truth is: let us ask instead how we can recognize it reliably when it appears. Four factors determine the truthfulness of a theory or explanation: congruence, consistency, coherence, and usefulness.

• A true theory is congruent with our experience – meaning, it fits the facts. It is in principle falsifiable, but nothing falsifying it has been found. One way we can infer that our theory is congruent with the facts as we experience them is when what we experience is predictable from the theory. But truth is always provisional, not an end state. When we discover new facts, we may need to change our theory.

• A true theory is internally consistent . It has no contradictions within itself, and it fits together elegantly. The principle of consistency (same as the principle of non-contradiction) allows us to infer things consistent with what we already know. An inconsistent theory – one that contains contradictions – does not allow us to do this.

• Alongside this criterion, a true theory is coherent with everything else we consider true . It confirms, or at least fails to contradict, the rest of our established knowledge, where ‘knowledge’ means beliefs for which we can give rigorous reasons. The physical sciences – physics, chemistry, biology, geology and astronomy – all reinforce each other, for example.

• A true theory is useful . It gives us mastery. When we act on the basis of a true theory or explanation, our actions are successful. What is true works to organize our thought and our practice, so that we are able both to reason with logical rigor to true conclusions and to handle reality effectively. Truth enables us to exert our power, in the sense of our ability to get things done, successfully. It has predictive power, allowing us to make good choices concerning what is likely to happen.

Does this mean that what is useful is true? That is not a useful question, as it’s not the sole criterion. Rather, if a theory is congruent with our experience, internally consistent, coherent with everything else we know, and useful for organizing our thinking and practice, then we can confidently consider it true.

Proposition P is true if P is the case, and P is the case if P is true. Together with all other propositions which meet the same criterion, P can then claim to inhabit the realm of Truth.

But is P the case? P may be a sincerely-held belief; but this alone is insufficient to establish its truth. Claims to truth must be well justified. Those beliefs based on prediction and forecast are particularly suspect, and can usually be discounted. The recent prediction that ‘the world will end at 6.00pm on 21 May 2011’ is an example. There was never any systematic attempt at justification, and without this any claim to truth is seriously (and usually fatally) flawed. If it cannot be shown that a belief either corresponds to a known fact, coheres with a ‘consistent and harmonious’ system of beliefs, or prompts actions which have desirable outcomes (the pragmatic approach), then any claim to Truth becomes impossible to justify.

The realm of Truth may contain those arising from mystical convictions, which are more difficult to justify than those based on observations. Although attempts are made to pragmatically justify religious beliefs, the many competing claims leave us in confusion. As regards Truth in the Art-World, Aquinas identifies Truth with Beauty, and defines the truth in art as ‘that which pleases in the very apprehension of it’.

So, Truth is the realm populated by well-justified beliefs. To a certain extent truth is subjective, although a belief gains greater currency by its wider acknowledgment.

Truth is not constant. Some beliefs which were held to be true are now considered false, and some for which truth is now claimed may be deemed false in the future, and vice versa . Truth is good for helping us decide how to act, because it serves as a standard for making some sort of sense of a world populated also by half-truths and untruths.

Our ancestors did themselves (and us) a great favour when they began using noises to communicate. They probably started with “Hide!” “Wolves!” “Eat!/Don’t eat!” and “Mine/Yours!” The invention of language enabled us to do many things. We could use it to describe the world as we found it; but we could also use it to create things, such as boundaries and private property. As John Searle has argued, the vast structure of our social world, including our laws, businesses, politics, economics and entertainments, has been built out of language.

Telling the truth is just one of the uses of language. Telling the truth is complicated by the fact that we live in a hybrid world, partly natural, partly invented. “Earth rotates” is a true account of a natural given. “Earth rotates once every 24 hours” is only true within the language community which imposes that system of time-measurement on the given reality. Another complication is that we ourselves are physical objects which can be described using objective terms, but we are also social beings, in roles, relationships and structures which are all man-made.

Classifications are a key component of language. A sentence of the simple form ‘X is Y’ can locate an individual within a class (‘Socrates is a man’) or one class within another (‘Daisies are weeds’). Some classifications are givens in nature (the periodic table, biological taxonomy, physical laws) while others are inventions (social roles, types (uses) of furniture, parts of speech). Sentences can mix natural classes with inventions: ‘daisies’ refers to a class of plant given in nature, whereas ‘weeds’ refers to an invented class of ‘dislikeable plants’. In their search for truth the natural sciences seek to discover natural classifications, as distinct from social inventions.

True descriptions are like maps. Some descriptions map objective reality, as the natural sciences do, which is like a map of physical contours. Other descriptions map our socially-constructed world, as journalists, historians, novelists and theologians do, like a map showing political borders.

We have made great progress since our ancestors first grunted at each other. Language was essential to that progress and it provided the true/false distinction which enabled us to analyse and understand the natural world which sustains us.

Les Reid, Belfast

I would like to say that truth exists outside of us, for all to see. Unfortunately, humans can be stubborn, and so the actual pinning down of what a truth is is more complicated. Society plays host to two types of truths; subjective truth and objective truth. Subjective truth is given to us through our individual expe riences in relation to those around us: in short, it’s the truths we have been raised with. Objective truth is discovered by a search which is critical of our experiences until sufficient evidence has been gathered. The subjective truth is not always in opposition to the objective truth, but it does depend on the subject valuing their worldview more than others’.

Our preference as a society is, I believe, revealed through our use of language. If we say: “Look, the sun is going down” we are speaking from our subjective viewpoint. It is true from our individual standpoint, but it is not a truth in the objective sense. The truth, in an objective sense, is that we live on a planet which spins on its axis and it orbits the Sun. So in fact what we should say is “Look, the earth is spinning away from the Sun and will soon obstruct our view of it.” This may seem a pedantic point to make; however, if our language does not reflect the objective truth, it must mean that truth stands firmly in the subjective camp. Based on our use of language in the majority of situations, an alien may then well judge us to be very ignorant, and that our truth is self-serving.

It could be said that subjective truth isn’t truth at all, more belief ; but because as a society our values give more strength to the individual and to personal experience, we must bow to the power of the individual belief as truth, as we seem to do through our everyday use of language.

Everyone knows perfectly well what truth is – everyone except Pontius Pilate and philosophers. Truth is the quality of being true, and being true is what some statements are. That is to say, truth is a quality of the propositions which underlie correctly-used statements.

What does that mean? Well, imagine a man who thinks that Gordon Brown is still the British PM, and that Gordon Brown was educated at Edinburgh (as he was). When he says “The PM was educated at Edinburgh”, what he means is clearly true: the person he is calling the PM was educated at Edinburgh. Therefore, if (somewhat counter-intuitively) we say the statement itself is true, we’re saying that what the statement actually means is true: that what anyone who understands the meanings and references of all the words in the statement means, is true. Nonetheless, it is perfectly natural to say that a statement itself is true; people who think this would say that the above statement, as uttered by the man who thinks Gordon Brown is PM, is false (even though what he meant by it is true).

However, to generalise, it is not really the statement itself that is true (or false), but what is meant by it. It can’t be the possible state of affairs described by the statement which is true: states of affairs are not true, they just exist. Rather, there must be some wordless ‘proposition’ nailed down by the statement which describes that state of affairs, and which could be expressed accurately in various forms of words (in a variety of statements); and it is that proposition which is either true or false. So when we say that a particular statement is true, that must be shorthand for “the proposition meant by someone who utters that statement, in full knowledge of the meanings and references of the words in it, is true.”

I dilute my solution, place it into a cuvette, and take a reading with the spectrophotometer: 0.8. I repeat the procedure once more and get 0.7; and once again to get 0.9. From this I get the average of 0.8 that I write in my lab-book. The variation is probably based upon tiny inconsistencies in how I am handling the equipment, so three readings should be sufficient for my purposes. Have I discovered the truth? Well yes – I have a measurement that seems roughly consistent, and should, assuming that my notes are complete and my spectrophotometer has been calibrated, be repeatable in many other labs around the world. However, this ‘truth’ is meaningless without some understanding of what I am trying to achieve. The spectrophotometer is set at 280nm, which – so I have been taught – is the wavelength used to measure protein concentration. I know I have made up my solution from a bottle labelled ‘albumin’, which – again, as I have been taught – is a protein. So my experiment has determined the truth of how much protein is in the cuvette. But again, a wider context is needed. What is a protein, how do spectrophotometers work, what is albumin, why do I want to know the concentration in the first place? Observations are great, but really rather pointless without a reason to make them, and without the theoretical knowledge for how to interpret them. Truth, even in science, is therefore highly contextual. What truth is varies not so much with different people, but rather with the narrative they are living by. Two people with a similar narrative will probably agree on how to treat certain observations, and might agree on a conclusion they call the truth, but as narratives diverge so too does agreement on what ‘truth’ might be. In the end, even in an entirely materialistic world, truth is just the word we use to describe an observation that we think fits into our narrative.

Truth is unique to the individual. As a phenomenologist, for me, that I feel hungry is more a truth than that 2+3=5. No truth can be ‘objectively verified’ – empirically or otherwise – and the criteria by which we define truths are always relative and subjective. What we consider to be true, whether in morality, science, or art, shifts with the prevailing intellectual wind, and is therefore determined by the social, cultural and technological norms of that specific era. Non-Euclidean geometry at least partially undermines the supposed tautological nature of geometry – usually cited as the cornerstone of the rationalist’s claims that reason can provide knowledge: other geometries are possible, and equally true and consistent. This means that the truth of geometry is once more inextricably linked with your personal perspective on why one mathematical paradigm is ‘truer’ than its viable alternatives.

In the end, humans are both fallible and unique, and any knowledge we discover, true or otherwise, is discovered by a human, finite, individual mind. The closest we can get to objective truth is intersubjective truth, where we have reached a general consensus due to our similar educations and social conditioning. This is why truths often don’t cross cultures. This is an idea close to ‘conceptual relativism’ – a radical development of Kant’s thinking which claims that in learning a language we learn a way of interpreting the world, and thus, to speak a different language is to inhabit a different subjective world.

So our definition of truth needs to be much more flexible than Plato, Descartes and other philosophers claim. I would say that a pragmatic theory of truth is closest: that truth is the ‘thing that works’; if some other set of ideas works better, then it is truer. This is a theory Nietzsche came close to accepting.

The lack of objective truth leaves us free to carve our own truths. As in Sartre’s existentialism, we aren’t trapped by objectivity; rather, the lack of eternal, immutable truths allows us to create what is true for ourselves. Truth is mine. My truth and your truth have no necessary relevance to each other. Because truth is subjective, it can play a much more unique and decisive role in giving life meaning; I am utterly free to choose my truths, and in doing so, I shape my own life. Without subjective truth, there can be no self-determination.

Andrew Warren, Eastleigh, Hants

Truth is interpersonal. We tell each other things, and when they work out we call them truths. When they don’t, we call them errors or, if we are not charitable, lies. What we take as truth depends on what others around us espouse. For many centuries European Christians believed that men had one fewer rib than women because the Bible says that Eve was created from Adam’s rib. Nobody bothered to count because everyone assumed it was true. And when they finally counted, it was because everyone agreed on the result that the real truth became known. Even when we are alone, truth is interpersonal. We express these truths or errors or lies to others and to ourselves in language; and, as Wittgenstein pointed out, there can be no private language.

But the most essential truth, the truth by which we all live our lives, is intensely personal, private. We might call this ‘Truth’, with a capital T. Even though each of us lives our life by Truth, it can be different for each person. Shall I believe and obey the Torah, the New Testament, the Quran, the Bhagavad Gita, the Zend Avesta, the Dhammapada? Or none of the above: shall I find my own Truth in my own way?

We thus need a community of seekers with a commitment to meta-Truth, recognizing that personal Truths are to be respected, even though any Truth will differ from someone else’s. But even in such a community, some beliefs would be acceptable, and others not: my belief that I am exceptional and deserve preferential treatment, perhaps because I alone have received a special revelation, is not likely to be shared by others. From within the in-group we look with fear and revulsion on those who deny the accepted beliefs. From outside, we admire those who hold aloft the light of truth amidst the darkness of human ignorance. And in every case it is we who judge, not I alone. Even the most personal Truth is adjudicated within a community and depends on the esteem of others.

Robert Tables, Blanco, TX

The word ‘true’ comes from the Anglo-Saxon ‘ treowe ’ meaning ‘believed’. ‘Believe’ itself is from ‘ gelyfan ’, ‘to esteem dear’. So etymologically, ‘truth’ would be something believed to be of some value, rather than necessarily being correct. ‘Believe’ is still used in the older sense, as in “I believe in democracy” – a different sense to ‘believing in Father Christmas’. Such ambiguity facilitates equivocation – useful to politicians, etc, who can be economical with the truth. One function of language is to conceal truth.

In an experiment by Solomon Asch, subjects were given pairs of cards. On one were three lines of different lengths; on the other card a single line. The test was to determine which of the three lines was the same length as the single line. The truth was obvious; but in the group of subjects all were stooges except one. The stooges called out answers, most of which were of the same, obviously wrong, line. The self-doubt thus incurred in the real subjects made only one quarter of them trust the evidence of their senses enough to pick the correct answer.

Schopenhauer noticed the reluctance of the establishment to engage with new ideas, choosing to ignore rather than risk disputing and refuting them. Colin Wilson mentions Thomas Kuhn’s contention that “once scientists have become comfortably settled with a certain theory, they are deeply unwilling to admit that there might be anything wrong with it” and links this with the ‘Right Man’ theory of writer A.E.Van Vogt. A ‘Right Man’ would never admit that he might be wrong. Wilson suggests that people start with the ‘truth’ they want to believe, and then work backwards to find supporting evidence. Similarly, Robert Pirsig says that ideas coming from outside orthodox establishments tend to be dismissed. Thinkers hit “an invisible wall of prejudice… nobody inside… is ever going to listen… not because what you say isn’t true, but solely because you have been identified as outside that wall.” He termed this a ‘cultural immune system’.

We may remember our experiences and relate them accurately; but as to complex things like history, politics, peoples’ motives, etc, the models of reality we have can at best be only partly true. We are naive if taken in by ‘spin’; we’re gullible, paranoid or crazy if we give credit to ‘conspiracy theories’; and, with limited knowledge of psychology, scientific method, the nature of politics etc, the ‘truth’ will tend to elude us there too.

As I gather amongst my fellow lovers of wisdom for another round of coffee, debate and discussion, I try to filter in the question I am trying to answer: ‘What is Truth?’ With many a moan and a sigh (and indeed a giggle from some), I try to wiggle out the truth from these B.A. philosophy students. I think it is interesting to examine why philosophy students should hate the question so much. It seems that the question itself is meaningless for some of them. “Really?” they asked, “Aren’t we a little too postmodern for that?” Actually, I reminded them, the question itself can be considered to be postmodern. Postmodernism is not the opposite of realism. Rather, postmodernism only questions the blatant acceptance of reality. If postmodernism did not ask the question of truth, but rather, assumed that [it is true that] there is no truth, it would be just as unassuming about truth as realism is.

“But wait,” said one crafty little Socrates, “You mentioned, realism: so are the questions of what is true and what is real the same question?” Then it became terribly frightening, because we entered into a debate about the relation between language and reality. We agreed amongst ourselves that it certainly seemed that both questions are roughly treated as equal, since when one questions certainty, one questions both truth and reality, and postmodernists certainly question both. The question then became: If Truth and Reality are so intimately connected, to what degree do we have access to reality, and what do we use to access this reality and come to truth? We perused the history of philosophy. It seemed to us that from Descartes to Kant (and some argued that even in phenomenology and existentialism) there has been an unhealthy relationship between us and reality/truth. Indeed, you could argue that a great deal of the history of Western philosophy was trying to deal with the problem of alienation, ie, the alienation of human beings from reality and truth.

‘Truth’ has a variety of meanings, but the most common definitions refer to the state of being in accordance with facts or reality . There are various criteria, standards and rules by which to judge the truth that statements profess to claim. The problem is how can there be assurance that we are in accordance with facts or realities when the human mind perceives, distorts and manipulates what it wants to see, hear or decipher. Perhaps a better definition of truth could be, an agreement of a judgment by a body of people on the facts and realities in question .

I have indeed always been amazed at how far people are willing to be accomplices to the vast amount of lies, dishonesty and deception which continuously goes on in their lives. The Global Financial Crisis, the investment scandal of Bernard Madoff, the collapse of Enron, and the war in Iraq, are familiar stories of gross deception from the past decade. The Holocaust is another baffling case of a horrendous genocide that was permitted to take place across a whole continent which seemed completely oblivious to reality. And yet even today we find people who deny such an atrocity having taken place, in spite of all the evidence to the contrary.

Discovering the truth will be a hurtful and painful experience when the facts or realities turn out to be different from what is expected. Yet there ought to be no grounds for despair if we accept that the ideal of truth, like all other virtues, can be approached rather than attained. This ideal truth can be glimpsed if we manage to be sceptical, independent and open-minded when presented with the supposed facts and realities. However, in searching for the truth, precaution must be taken, that we are not trapped into a life overshadowed by fear, suspicion and cynicism, since this would suspend us in a state of continuous tension. One might easily conclude that living a life not concerned with probing for the truth would perhaps after all yield greater peace of mind. But it is the life that continuously struggles with the definition of the truth that will ultimately give scope and meaning to human existence.

Truth is one of the central subjects in philosophy. It is also one of the largest. Truth has been a topic of discussion in its own right for thousands of years. Moreover, a huge variety of issues in philosophy relate to truth, either by relying on theses about truth, or implying theses about truth.

It would be impossible to survey all there is to say about truth in any coherent way. Instead, this essay will concentrate on the main themes in the study of truth in the contemporary philosophical literature. It will attempt to survey the key problems and theories of current interest, and show how they relate to one-another. A number of other entries investigate many of these topics in greater depth. Generally, discussion of the principal arguments is left to them. The goal of this essay is only to provide an overview of the current theories.

The problem of truth is in a way easy to state: what truths are, and what (if anything) makes them true. But this simple statement masks a great deal of controversy. Whether there is a metaphysical problem of truth at all, and if there is, what kind of theory might address it, are all standing issues in the theory of truth. We will see a number of distinct ways of answering these questions.

1.1 The correspondence theory

1.1.1 the origins of the correspondence theory, 1.1.2 the neo-classical correspondence theory, 1.2 the coherence theory, 1.3 pragmatist theories, 2.1 sentences as truth-bearers, 2.2 convention t, 2.3 recursive definition of truth, 2.4 reference and satisfaction, 3.1 correspondence without facts, 3.2 facts again, 3.3. truthmakers, 4.1 realism and truth, 4.2 anti-realism and truth, 4.3 anti-realism and pragmatism, 5.1 the redundancy theory, 5.2 minimalist theories, 5.3 other aspects of deflationism, 6.1 truth-bearers, 6.2 truth and truth conditions, 6.3 truth conditions and deflationism, 6.4 truth and the theory of meaning, 6.5 the coherence theory and meaning, 6.6 truth and assertion, bibliography, other internet resources, related entries, 1. the neo-classical theories of truth.

Much of the contemporary literature on truth takes as its starting point some ideas which were prominent in the early part of the 20th century. There were a number of views of truth under discussion at that time, the most significant for the contemporary literature being the correspondence, coherence, and pragmatist theories of truth.

These theories all attempt to directly answer the nature question : what is the nature of truth? They take this question at face value: there are truths, and the question to be answered concerns their nature. In answering this question, each theory makes the notion of truth part of a more thoroughgoing metaphysics or epistemology. Explaining the nature of truth becomes an application of some metaphysical system, and truth inherits significant metaphysical presuppositions along the way.

The goal of this section is to characterize the ideas of the correspondence, coherence and pragmatist theories which animate the contemporary debate. In some cases, the received forms of these theories depart from the views that were actually defended in the early 20th century. We thus dub them the ‘neo-classical theories’. Where appropriate, we pause to indicate how the neo-classical theories emerge from their ‘classical’ roots in the early 20th century.

Perhaps the most important of the neo-classical theories for the contemporary literature is the correspondence theory. In spite of its importance, it is strikingly difficult to find an accurate citation in the early 20th century for the received neo-classical view. Furthermore, the way the correspondence theory actually emerged will provide some valuable reference points for contemporary debate. For these reasons, we dwell on the origins of the correspondence theory at greater length than those of the other neo-classical views, before turning to its contemporary neo-classical form.

The basic idea of the correspondence theory is that what we believe or say is true if it corresponds to the way things actually are—to the facts. This idea can be seen in various forms throughout the history of philosophy. Its modern history starts with the beginnings of analytic philosophy at the turn of the 20th century, particularly in the work of G. E. Moore and Bertrand Russell.

Let us pick up the thread of this story in the years between 1898 and about 1910. These years are marked by Moore and Russell's rejection of idealism. Yet at this point, they do not hold a correspondence theory of truth. Indeed Moore (1899) sees the correspondence theory as a source of idealism, and rejects it. Russell follows Moore in this regard. (For discussion of Moore's early critique of idealism, where he rejects the correspondence theory of truth, see Baldwin (1991). Hylton (1990) provides an extensive discussion of Russell in the context of British idealism.)

In this period, Moore and Russell hold a version of the identity theory of truth . They say comparatively little about it, but it is stated briefly in Moore (1902); Moore (1899) and Russell (1904). According to the identity theory, a true proposition is identical to a fact. Specifically, in Moore and Russell's hands, the theory begins with propositions, understood as the objects of beliefs and other propositional attitudes. Propositions are what are believed, and give the contents of beliefs. They are also, according to this theory, the primary bearers of truth. When a proposition is true, it is identical to a fact, and a belief in that proposition is correct.

The identity theory Moore and Russell espoused takes truth to be a property of propositions. Furthermore, taking up an idea familiar to readers of Moore, the property of truth is a simple unanalyzable property. Facts are understood as simply those propositions which are true. There are true propositions and false ones, and facts just are true propositions. There is thus no “difference between truth and the reality to which it is supposed to correspond” (Moore, 1902, p. 21). (For further discussion of the identity theory of truth, see Baldwin (1991), Cartwright (1987), and the entry on the identity theory of truth .)

Moore and Russell came to reject the identity theory of truth in favor of a correspondence theory, sometime around 1910 (as we see in Moore, 1953, which reports lectures he gave in 1910-1911, and Russell, 1910b). They do so because they came to reject the existence of propositions. Why? Among reasons, they came to doubt that there could be any such things as false propositions, and then concluded that there are no such things as propositions at all.

Why did Moore and Russell find false propositions problematic? A full answer to this question is a point of scholarship that would take us too far afield. (Moore himself lamented that he could not “put the objection in a clear and convincing way” (1953, p. 263), but see Cartwright (1987) for a careful and clear exploration of the arguments.) But very roughly, the identification of facts with true propositions left them unable to see what a false proposition could be other than something which is just like a fact, though false. If such things existed, we would have fact-like things in the world, which Moore and Russell now see as enough to make false propositions count as true. Hence, they cannot exist, and so there are no false propositions. As Russell (1956, p. 223) later says, propositions seem to be at best “curious shadowy things” in addition to facts.

As Cartwright (1987) reminds us, it is useful to think of this argument in the context of Russell's slightly earlier views about propositions. As we see clearly in Russell (1903), for instance, he takes propositions to have constituents. But they are not mere collections of constituents, but a ‘unity’ which brings the constituents together. (We thus confront the ‘problem of the unity of the proposition’.) But what, we might ask, would be the ‘unity’ of a proposition that (Samuel) Ramey sings—with constituents Ramey and singing—except Ramey bearing the property of singing? If that is what the unity consists in, then we seem to have nothing other than the fact that Ramey sings. But then we could not have genuine false propositions without having false facts.

As Cartwright also reminds us, there is some reason to doubt the cogency of this sort of argument. But let us put the assessment of the arguments aside, and continue the story. From the rejection of propositions a correspondence theory emerges. The primary bearers of truth are no longer propositions, but beliefs themselves. In a slogan:

A belief is true if and only if it corresponds to a fact .

Views like this are held by Moore (1953) and Russell (1910b); Russell (1912). Of course, to understand such a theory, we need to understand the crucial relation of correspondence, as well as the notion of a fact to which a belief corresponds. We now turn to these questions. In doing so, we will leave the history, and present a somewhat more modern reconstruction of a correspondence theory.

The correspondence theory of truth is at its core an ontological thesis: a belief is true if there exists an appropriate entity—a fact—to which it corresponds. If there is no such entity, the belief is false.

Facts, for the neo-classical correspondence theory, are entities in their own right. Facts are generally taken to be composed of particulars and properties and relations or universals, at least. The neo-classical correspondence theory thus only makes sense within the setting of a metaphysics that includes such facts. Hence, it is no accident that as Moore and Russell turn away from the identity theory of truth, the metaphysics of facts takes on a much more significant role in their views. This perhaps becomes most vivid in the later Russell (1956, p. 182), where the existence of facts is the “first truism.” (The influence of Wittgenstein's ideas to appear in the Tractatus (1922) on Russell in this period was strong.)

Consider, for example, the belief that Ramey sings. Let us grant that this belief is true. In what does its truth consist, according to the correspondence theory? It consists in there being a fact in the world, built from the individual Ramey, and the property of singing. Let us denote this < Ramey , Singing >. This fact exists. In contrast, the world (we presume) contains no fact < Ramey , Dancing >. The belief that Ramey sings stands in the relation of correspondence to the fact < Ramey , Singing >, and so the belief is true.

What is the relation of correspondence? One of the standing objections to the classical correspondence theory is that a fully adequate explanation of correspondence proves elusive. But for a simple belief, like that Ramey sings, we can observe that the structure of the fact < Ramey , Singing > matches the subject-predicate form of the that -clause which reports the belief, and may well match the structure of the belief itself.

So far, we have very much the kind of view that Moore and Russell would have found congenial. But the modern form of the correspondence theory seeks to round out the explanation of correspondence by appeal to propositions . Indeed, it is common to base a correspondence theory of truth upon the notion of a structured proposition . Propositions are again cast at the contents of beliefs and assertions, and propositions have structure which at least roughly corresponds to the structure of sentences. At least, for simple beliefs like that Ramey sings, the proposition has the same subject predicate structure as the sentence. (Proponents of structured propositions, such as Kaplan (1989), often look to Russell (1903) for inspiration, and find unconvincing Russell's reasons for rejecting them.)

With facts and structured propositions in hand, an attempt may be made to explain the relation of correspondence. Correspondence holds between a proposition and a fact when the proposition and fact have the same structure, and the same constituents at each structural position. When they correspond, the proposition and fact thus mirror each-other. In our simple example, we might have:

proposition that Ramey sings ↓ ↓ fact < Ramey , Singing >

Propositions, though structured like facts, can be true or false. In a false case, like the proposition that Ramey dances, we would find no fact at the bottom of the corresponding diagram. Beliefs are true or false depending on whether the propositions which are believed are.

We have sketched this view for simple propositions like the proposition that Ramey sings. How to extend it to more complex cases, like general propositions or negative propositions, is an issue we will not delve into here. It requires deciding whether there are complex facts, such as general facts or negative facts, or whether there is a more complex relation of correspondence between complex propositions and simple facts. (The issue of whether there are such complex facts marks a break between Russell (1956) and Wittgenstein (1922) and the earlier views which Moore (1953) and Russell (1912) sketch.)

According to the correspondence theory as sketched here, what is key to truth is a relation between propositions and the world, which obtains when the world contains a fact that is structurally similar to the proposition. Though this is not the theory Moore and Russell held, it weaves together ideas of theirs with a more modern take on (structured) propositions. We will thus dub it the neo-classical correspondence theory. This theory offers us a paradigm example of a correspondence theory of truth.

The leading idea of the correspondence theory is familiar. It is a form of the older idea that true beliefs show the right kind of resemblance to what is believed. In contrast to earlier empiricist theories, the thesis is not that one's ideas per se resemble what they are about. Rather, the propositions which give the contents of one's true beliefs mirror reality, in virtue of entering into correspondence relations to the right pieces of it.

In this theory, it is the way the world provides us with appropriately structured entities that explains truth. Our metaphysics thus explains the nature of truth, by providing the entities needed to enter into correspondence relations.

For more on the correspondence theory, see the entry on the correspondance theory of truth .

Though initially the correspondence theory was seen by its developers as a competitor to the identity theory of truth, it was also understood as opposed to the coherence theory of truth.

We will be much briefer with the historical origins of the coherence theory than we were with the correspondence theory. Like the correspondence theory, versions of the coherence theory can be seen throughout the history of philosophy. (See, for instance, Walker (1989) for a discussion of its early modern lineage.) Like the correspondence theory, it was important in the early 20th century British origins of analytic philosophy. Particularly, the coherence theory of truth is associated with the British idealists to whom Moore and Russell were reacting.

Many idealists at that time did indeed hold coherence theories. Let us take as an example Joachim (1906). (This is the theory that Russell (1910a) attacks.) Joachim says that:

Truth in its essential nature is that systematic coherence which is the character of a significant whole (p. 76).

We will not attempt a full exposition of Joachim's view, which would take us well beyond the discussion of truth into the details of British idealism. But a few remarks about his theory will help to give substance to the quoted passage.

Perhaps most importantly, Joachim talks of ‘truth’ in the singular. This is not merely a turn of phrase, but a reflection of his monistic idealism. Joachim insists that what is true is the “whole complete truth” (p. 90). Individual judgments or beliefs are certainly not the whole complete truth. Such judgments are, according to Joachim, only true to a degree. One aspect of this doctrine is a kind of holism about content, which holds that any individual belief or judgment gets its content only in virtue of being part of a system of judgments. But even these systems are only true to a degree, measuring the extent to which they express the content of the single ‘whole complete truth’. Any real judgment we might make will only be partially true.

To flesh out Joachim's theory, we would have to explain what a significant whole is. We will not attempt that, as it leads us to some of the more formidable aspects of his view, e.g., that it is a “process of self-fulfillment” (p. 77). But it is clear that Joachim takes ‘systematic coherence’ to be stronger than consistency. In keeping with his holism about content, he rejects the idea that coherence is a relation between independently identified contents, and so finds it necessary to appeal to ‘significant wholes’.

As with the correspondence theory, it will be useful to recast the coherence theory in a more modern form, which will abstract away from some of the difficult features of British idealism. As with the correspondence theory, it can be put in a slogan:

A belief is true if and only if it is part of a coherent system of beliefs.

To further the contrast with the neo-classical correspondence theory, we may add that a proposition is true if it is the content of a belief in the system, or entailed by a belief in the system. We may assume, with Joachim, that the condition of coherence will be stronger than consistency. With the idealists generally, we might suppose that features of the believing subject will come into play.

This theory is offered as an analysis of the nature of truth, and not simply a test or criterion for truth. Put as such, it is clearly not Joachim's theory (it lacks his monism, and he rejects propositions), but it is a standard take on coherence in the contemporary literature. (It is the way the coherence theory is given in Walker (1989), for instance.) Let us take this as our neo-classical version of the coherence theory. The contrast with the correspondence theory of truth is clear. Far from being a matter of whether the world provides a suitable object to mirror a proposition, truth is a matter of how beliefs are related to each-other.

The coherence theory of truth enjoys two sorts of motivations. One is primarily epistemological. Most coherence theorists also hold a coherence theory of knowledge; more specifically, a coherence theory of justification. According to this theory, to be justified is to be part of a coherent system of beliefs. An argument for this is often based on the claim that only another belief could stand in a justification relation to a belief, allowing nothing but properties of systems of belief, including coherence, to be conditions for justification. Combining this with the thesis that a fully justified belief is true forms an argument for the coherence theory of truth. (An argument along these lines is found in Blanshard (1939), who holds a form of the coherence theory closely related to Joachim's.)

The steps in this argument may be questioned by a number of contemporary epistemological views. But the coherence theory also goes hand-in-hand with its own metaphysics as well. The coherence theory is typically associated with idealism. As we have already discussed, forms of it were held by British idealists such as Joachim, and later by Blanshard (in America). An idealist should see the last step in the justification argument as quite natural. More generally, an idealist will see little (if any) room between a system of beliefs and the world it is about, leaving the coherence theory of truth as an extremely natural option.

It is possible to be an idealist without adopting a coherence theory. (For instance, many scholars read Bradley as holding a version of the identity theory of truth. See Baldwin (1991) for some discussion.) However, it is hard to see much of a way to hold the coherence theory of truth without maintaining some form of idealism. If there is nothing to truth beyond what is to be found in an appropriate system of beliefs, then it would seem one's beliefs constitute the world in a way that amounts to idealism. (Walker (1989) argues that every coherence theorist must be an idealist, but not vice-versa.)

The neo-classical correspondence theory seeks to capture the intuition that truth is a content-to-world relation. It captures this in the most straightforward way, by asking for an object in the world to pair up with a true proposition. The neo-classical coherence theory, in contrast, insists that truth is not a content-to-world relation at all; rather, it is a content-to-content, or belief-to-belief, relation. The coherence theory requires some metaphysics which can make the world somehow reflect this, and idealism appears to be it. (A distant descendant of the neo-classical coherence theory that does not require idealism will be discussed in section 6.5 below.)

For more on the coherence theory, see the entry on the coherence theory of truth .

A different perspective on truth was offered by the American pragmatists. As with the neo-classical correspondence and coherence theories, the pragmatist theories go with some typical slogans. For example, Peirce is usually understood as holding the view that:

Truth is the end of inquiry.

(See, for instance Hartshorne et al., 1931-58, §3.432.) Both Peirce and James are associated with the slogan that:

Truth is satisfactory to believe.

James (e.g., 1907) understands this principle as telling us what practical value truth has. True beliefs are guaranteed not to conflict with subsequent experience. Likewise, Peirce's slogan tells us that true beliefs will remain settled at the end of prolonged inquiry. Peirce's slogan is perhaps most typically associated with pragmatist views of truth, so we might take it to be our canonical neo-classical theory. However, the contemporary literature does not seem to have firmly settled upon a received ‘neo-classical’ pragmatist theory.

In her reconstruction (upon which we have relied heavily), Haack (1976) notes that the pragmatists' views on truth also make room for the idea that truth involves a kind of correspondence, insofar as the scientific method of inquiry is answerable to some independent world. Peirce, for instance, does not reject a correspondence theory outright; rather, he complains that it provides merely a ‘nominal’ or ‘transcendental’ definition of truth (e.g Hartshorne et al., 1931-58, §5.553, 5.572), which is cut off from practical matters of experience, belief, and doubt (§5.416). (See Misak (1991) for an extended discussion.)

This marks an important difference between the pragmatist theories and the coherence theory we just considered. Even so, pragmatist theories also have an affinity with coherence theories, insofar as we expect the end of inquiry to be a coherent system of beliefs. As Haack also notes, James maintains an important verificationist idea: truth is what is verifiable. We will see this idea re-appear in section 4.

James' views are discussed further in the entry on William James . Peirce's views are discussed further in the entry on Charles Sanders Peirce .

2. Tarski's theory of truth

Modern forms of the classical theories survive. Many of these modern theories, notably correspondence theories, draw on ideas developed by Tarski.

In this regard, it is important to bear in mind that his seminal work on truth (1935) is very much of a piece with other works in mathematical logic, such as his (1931), and as much as anything this work lays the ground-work for the modern subject of model theory—a branch of mathematical logic, not the metaphysics of truth. In this respect, Tarski's work provides a set of highly useful tools that may be employed in a wide range of philosophical projects.

Tarski's work has a number of components, which we will consider in turn.

In the classical debate on truth at the beginning of the 20th century we considered in section 1, the issue of truth-bearers was of great significance. For instance, Moore and Russell's turn to the correspondence theory was driven by their views on whether there are propositions to be the bearers of truth. Many theories we reviewed took beliefs to be the bearers of truth.

In contrast, Tarski and much of the subsequent work on truth takes sentences to be the primary bearers of truth. This is not an entirely novel development: Russell (1956) also takes truth to apply to sentence (which he calls ‘propositions’ in that text). But whereas much of the classical debate takes the issue of the primary bearers of truth to be a substantial and important metaphysical one, Tarski is quite casual about it. His primary reason for taking sentences as truth-bearers is convenience, and he explicitly distances himself from any commitment about the philosophically contentious issues surrounding other candidate truth-bearers (e.g., Tarski, 1944). (Russell (1956) makes a similar suggestion that sentences are the appropriate truth-bearers “for the purposes of logic” (p. 184), though he still takes the classical metaphysical issues to be important.)

We will return to the issue of the primary bearers of truth in section 6.1. For the moment, it will be useful to simply follow Tarski's lead. But it should be stressed that for this discussion, sentences are fully interpreted sentences, having meanings. We will also assume that the sentences in question do not change their content across occasions of use, i.e., that they display no context-dependence. We are taking sentences to be what Quine (1960) calls ‘eternal sentences’.

In some places (e.g., Tarski, 1944), Tarski refers to his view as the ‘semantic conception of truth’. It is not entirely clear just what Tarski had in mind by this, but it is clear enough that Tarski's theory defines truth for sentences in terms of concepts like reference and satisfaction, which are intimately related to the basic semantic functions of names and predicates (according to many approaches to semantics).

Let us suppose we have a fixed language L whose sentences are fully interpreted. The basic question Tarski poses is what an adequate theory of truth for L would be. Tarski's answer is embodied in what he calls Convention T :

An adequate theory of truth for L must imply, for each sentence φ of L

⌈ φ ⌉  is true if and only if φ .

(We have simplified Tarski's presentation somewhat.) This is an adequacy condition for theories, not a theory itself. Given the assumption that L is fully interpreted, we may assume that each sentence φ in fact has a truth value. In light of this, Convention T guarantees that the truth predicate given by the theory will be extensionally correct , i.e., have as its extension all and only the true sentences of L .

Convention T draws our attention to the biconditionals of the form

⌈   ⌈ φ ⌉ is true if and only if φ ⌉ ,

which are usually called the Tarski biconditionals for a language L .

Tarski does not merely propose a condition of adequacy for theories of truth, he also shows how to meet it. One of his insights is that if the language L displays the right structure, then truth for L can be defined recursively. For instance, let us suppose that L is a simple formal language, containing two atomic sentences ‘snow is white’ and ‘grass is green’, and the sentential connectives ∨ and ¬.

In spite of its simplicity, L contains infinitely many distinct sentences. But truth can be defined for all of them by recursion.

• ‘Snow is white’ is true if and only if snow is white.
• ‘Grass is green’ is true if and only if grass is green.
• ⌈ φ ∨ ψ ⌉ is true if and only if ⌈ φ ⌉ is true or ⌈ ψ ⌉ is true.
• ⌈ ¬φ ⌉ is true if and only if it is not the case that ⌈ φ ⌉ is true.

This theory satisfies Convention T.

This may look trivial, but in defining an extensionally correct truth predicate for an infinite language with four clauses, we have made a modest application of a very powerful technique.

Tarski's techniques go further, however. They do not stop with atomic sentences. Tarski notes that truth for each atomic sentence can be defined in terms of two closely related notions: reference and satisfaction . Let us consider a language L ′ , just like L except that instead of simply having two atomic sentences, L ′ breaks atomic sentences into terms and predicates. L ′ contains terms ‘snow’ and ‘grass’ (let us engage in the idealization that these are simply singular terms), and predicates ‘is white’ and ‘is green’. So L ′ is like L , but also contains the sentences ‘Snow is green’ and ‘Grass is white’.)

We can define truth for atomic sentences of L ′ in the following way.

• ‘Snow’ refers to snow.
• ‘Grass’ refers to grass.
• a satisfies ‘is white’ if and only if a is white.
• a satisfies ‘is green’ if and only if a is green.
• For any atomic sentence ⌈ t is P ⌉ : ⌈ t is P ⌉ is true if and only if the referent of ⌈ t ⌉ satisfies ⌈ P ⌉ .

One of Tarski's key insights is that the apparatus of satisfaction allows for a recursive definition of truth for sentences with quantifiers , though we will not examine that here. We could repeat the recursion clauses for L to produce a full theory of truth for L ′.

Let us say that a Tarskian theory of truth is a recursive theory, built up in ways similar to the theory of truth for L ′. Tarski goes on to demonstrate some key applications of such a theory of truth. A Tarskian theory of truth for a language L can be used to show that theories in L are consistent. This was especially important to Tarski, who was concerned the Liar paradox would make theories in languages containing a truth predicate inconsistent.

3. Correspondence revisited

The correspondence theory of truth expresses the very natural idea that truth is a content-to-world or word-to-world relation: what we say or think is true or false in virtue of the way the world turns out to be. We suggested that, against a background like the metaphysics of facts, it does so in a straightforward way. But the idea of correspondence is certainly not specific to this framework. Indeed, it is controversial whether a correspondence theory should rely on any particular metaphysics at all. The basic idea of correspondence, as Tarski (1944) and others have suggested, is captured in the slogan from Aristotle's Metaphysics Γ 7.27, “to say of what is that it is, or of what is not that it is not, is true” (Ross, 1928). ‘What is’, it is natural enough to say, is a fact, but this natural turn of phrase may well not require a full-blown metaphysics of facts.

Yet without the metaphysics of facts, the notion of correspondence as discussed in section 1.1 loses substance. This has led to two distinct strands in contemporary thinking about the correspondence theory. One strand seeks to recast the correspondence theory in a way that does not rely on any particular ontology. Another seeks to find an appropriate ontology for correspondence, either in terms of facts or other entities. We will consider each in turn.

Tarski himself sometimes suggested that his theory was a kind of correspondence theory of truth. Whether his own theory is a correspondence theory, and even whether it provides any substantial philosophical account of truth at all, is a matter of controversy. (One rather drastic negative assessment from Putnam (1985-86, p. 333) is that “As a philosophical account of truth, Tarski's theory fails as badly as it is possible for an account to fail.”) But a number of philosophers (e.g., Davidson, 1969; Field, 1972) have seen Tarski's theory as providing at least the core of a correspondence theory of truth which dispenses with the metaphysics of facts.

Tarski's theory shows how truth for a sentence is determined by certain properties of its constituents; in particular, by properties of reference and satisfaction (as well as by the logical constants). As it is normally understood, reference is the preeminent word-to-world relation. Satisfaction is naturally understood as a word-to-world relation as well, which relates a predicate to the things in the world that bear it. The Tarskian recursive definition shows how truth is determined by reference and satisfaction, and so is in effect determined by the things in the world we refer to and the properties they bear. This, one might propose, is all the correspondence we need. It is not correspondence of sentences or propositions to facts; rather, it is correspondence of our expressions to objects and the properties they bear, and then ways of working out the truth of claims in terms of this.

This is certainly not the neo-classical idea of correspondence. In not positing facts, it does not posit any single object to which a true proposition or sentence might correspond. Rather, it shows how truth might be worked out from basic word-to-world relations. However, a number of authors have noted that Tarski's theory cannot by itself provide us with such an account of truth. As we will discuss more fully in section 4.2, Tarski's apparatus is in fact compatible with theories of truth that are certainly not correspondence theories.

Field (1972), in an influential discussion and diagnosis of what is lacking in Tarski's account, in effect points out that whether we really have something worthy of the name ‘correspondence’ depends on our having notions of reference and satisfaction which genuinely establish word-to-world relations. (Field does not use the term ‘correspondence’, but does talk about e.g., the “connection between words and things” (p. 373).) By itself, Field notes, Tarski's theory does not offer an account of reference and satisfaction at all. Rather, it offers a number of disquotation clauses , such as:

These clauses have an air of triviality (though whether they are to be understood as trivial principles or statements of non-trivial semantic facts has been a matter of some debate). With Field, we might propose to supplement clauses like these with an account of reference and satisfaction. Such a theory should tell us what makes it the case that the word ‘snow’ refer to snow. (In 1972, Field was envisaging a physicalist account, along the lines of the causal theory of reference.) This should inter alia guarantee that truth is really determined by word-to-world relations, so in conjunction with the Tarskian recursive definition, it could provide a correspondence theory of truth.

Such a theory clearly does not rely on a metaphysics of facts. Indeed, it is in many ways metaphysically neutral, as it does not take a stand on the nature of particulars, or of the properties or universals that underwrite facts about satisfaction. However, it may not be entirely devoid of metaphysical implications, as we will discuss further in section 4.1.

There have been a number of correspondence theories that do make use of facts. Some are notably different from the neo-classical theory sketched in section 1.1. For instance, Austin (1950) proposes a view in which each statement (understood roughly as an utterance event) corresponds to both a fact or situation, and a type of situation. It is true if the former is of the latter type. This theory (which has been developed by situation theory (e.g., Barwise and Perry, 1986) rejects the idea that correspondence is a kind of mirroring between a fact and a proposition. Rather, correspondence relations to Austin are entirely conventional. As an ordinary language philosopher, Austin grounds his notion of fact more in linguistic usage than in an articulated metaphysics, but he defends his use of fact-talk in Austin (1961b).

In a somewhat more Tarskian spirit, formal theories of facts or states of affairs have also been developed. For instance, Taylor (1976) provides a recursive definition of a collection of ‘states of affairs’ for a given language. Taylor's states of affairs seem to reflect the notion of fact at work in the neo-classical theory, though as an exercise in logic, they are officially n -tuples of objects and intensions .

There are more metaphysically robust notions of fact in the current literature. For instance, Armstrong (1997) defends a metaphysics in which facts (under the name ‘states of affairs’) are metaphysically fundamental. The view has much in common with the neo-classical one. Like the neo-classical view, Armstrong endorses a version of the correspondence theory. States of affairs are truthmakers for propositions, though Armstrong argues that there may be many such truthmakers for a given proposition, and vice versa. (Armstrong also envisages a naturalistic account of propositions as classes of equivalent belief-tokens.)

Armstrong's primary argument is what he calls the ‘truthmaker argument’. It begins by advancing a truthmaker principle , which holds that for any given truth, there must be a truthmaker—a “something in the world which makes it the case, that serves as an ontological ground, for this truth” (p. 115). It is then argued that facts are the appropriate truthmakers.

In contrast to the approach to correspondence discussed in section 3.1, which offered correspondence with minimal ontological implications, this view returns to the ontological basis of correspondence that was characteristic of the neo-classical theory.

The truthmaker principle is often put as the schema:

If φ , then there is an x such that necessarily, if x exists, then φ .

(Fox (1987) proposed putting the principle this way, rather than explicitly in terms of truth.)

The truthmaker principle expresses the ontological aspect of the neo-classical correspondence theory. Not merely must truth obtain in virtue of word-to-world relations, but there must be a thing that makes each truth true.

The neo-classical correspondence theory, and Armstrong, cast facts as the appropriate truthmakers. However, it is a non-trivial step from the truthmaker principle to the existence of facts. There are a number of proposals in the literature for how other sorts of objects could be truthmakers; for instance, tropes (called ‘moments’, in Mulligan et al., 1984). Parsons (1999) argues that the truthmaker principle (presented in a somewhat different form) is compatible with there being only concrete particulars.

As we saw in discussing the neo-classical correspondence theory, truthmaker theories, and fact theories in particular, raise a number of issues. One which has been discussed at length, for instance, is whether there are negative facts . Negative facts would be the truthmakers for negated sentences. Russell (1956) notoriously expresses ambivalence about whether there are negative facts. Armstrong (1997) rejects them, while Beall (2000) defends them.

4. Realism and anti-realism

The neo-classical theories we surveyed in section 1 made the theory of truth an application of their background metaphysics (and in some cases epistemology). In section 2 and especially in section 3, we returned to the issue of what sorts of ontological commitments might go with the theory of truth. There we saw a range of options, from relatively ontologically non-committal theories, to theories requiring highly specific ontologies.

There is another way in which truth relates to metaphysics. Many ideas about realism and anti-realism are closely related to ideas about truth. Indeed, many approaches to questions about realism and anti-realism simply make them questions about truth.

In discussing the approach to correspondence of section 3.1, we noted that it has few ontological requirements. It relies on there being objects of reference, and something about the world which makes for determinate satisfaction relations; but beyond that, it is ontologically neutral. But as we mentioned there, this is not to say that it has no metaphysical implications. A correspondence theory of truth, of any kind, is often taken to embody a form of realism .

The key features of realism, as we will take it, are that:

• The world exists objectively, independently of the ways we think about it or describe it.
• Our thoughts and claims are about that world.

(Wright (1992) offers a nice statement of this way of thinking about realism.) These theses imply that our claims are objectively true or false, depending on how the world they are about is. The world that we represent in our thoughts or language is an objective world. (Realism may be restricted to some subject-matter, or range of discourse, but for simplicity, we will talk about only its global form.)

It is often argued that these theses require some form of the correspondence theory of truth. (Putnam (1978, p. 18) notes, “Whatever else realists say, they typically say that they believe in a ‘correspondence theory of truth’.”) At least, they are supported by the kind of correspondence theory without facts discussed in section 3.1, such as Field's proposal. Such a theory will provide an account of objective relations of reference and satisfaction, and show how these determine the truth or falsehood of what we say about the world. Field's own approach (1972) to this problem seeks a physicalist explanation of reference. But realism is a more general idea than physicalism. Any theory that provides objective relations of reference and satisfaction, and builds up a theory of truth from them, would give a form of realism. (Making the objectivity of reference the key to realism is characteristic of work of Putnam, e.g., 1978.)

Another important mark of realism expressed in terms of truth is the property of bivalence . As Dummett has stressed (e.g., 1959; 1976; 1983; 1991), a realist should see there being a fact of the matter one way or the other about whether any given claim is correct. Hence, one important mark of realism is that it goes together with the principle of bivalence : every truth-bearer (sentence or proposition) is true or false. In much of his work, Dummett has made this the characteristic mark of realism, and often identifies realism about some subject-matter with accepting bivalence for discourse about that subject-matter. At the very least, it captures a great deal of what is more loosely put in the statement of realism above.

Either the approach makes the theory of truth—or truth-and-reference—the primary vehicle for an account of realism. A theory of truth which substantiates bivalence, or a determinate reference relation, does most of the work of giving a realistic metaphysics. It might even simply be a realistic metaphysics.

We have thus turned on its head the relation of truth to metaphysics we saw in our discussion of the neo-classical correspondence theory in section 1.1. There, a correspondence theory of truth was built upon a substantial metaphysics. Here, we have seen how articulating a theory that captures the idea of correspondence can be crucial to providing a realist metaphysics. (For another perspective on realism and truth, see Alston (1996). Devitt (1984) offers an opposing view to the kind we have sketched here, which rejects any characterization of realism in terms of truth or other semantic concepts.)

In light of our discussion in section 1.1.1, we should pause to note that the connection between realism and the correspondence theory of truth is not absolute. When Moore and Russell held the identity theory of truth, they were most certainly realists. The right kind of metaphysics of propositions can support a realist view, as can a metaphysics of facts. The modern form of realism we have been discussing here seeks to avoid basing itself on such particular ontological commitments, and so prefers to rely on the kind of correspondence-without-facts approach discussed in section 3.1. This is not to say that realism will be devoid of ontological commitments, but the commitments will flow from whichever specific claims about some subject-matter are taken to be true.

For more on realism and truth, see the entry on realism .

It should come as no surprise that the relation between truth and metaphysics seen by modern realists can also be exploited by anti-realists. Many modern anti-realists see the theory of truth as the key to formulating and defending their views. With Dummett (e.g., 1959; 1976; 1991), we might expect the characteristic mark of anti-realism to be the rejection of bivalence.

Indeed, many contemporary forms of anti-realism may be formulated as theories of truth, and they do typically deny bivalence. Anti-realism comes in many forms, but let us take as an example a (somewhat crude) form of verificationism. Such a theory holds that a claim is correct just insofar as it is in principle verifiable , i.e., there is a verification procedure we could in principle carry out which would yield the answer that the claim in question was verified.

So understood, verificationism is a theory of truth. The claim is not that verification is the most important epistemic notion, but that truth just is verifiability. As with the kind of realism we considered in section 4.1, this view expresses its metaphysical commitments in its explanation of the nature of truth. Truth is not, to this view, a fully objective matter, independent of us or our thoughts. Instead, truth is constrained by our abilities to verify, and is thus constrained by our epistemic situation. Truth is to a significant degree an epistemic matter, which is typical of many anti-realist positions.

As Dummett says, the verificationist notion of truth does not appear to support bivalence. Any statement that reaches beyond what we can in principle verify or refute (verify its negation) will be a counter-example to bivalence. Take, for instance, the claim that there is some substance, say uranium, present in some region of the universe too distant to be inspected by us within the expected lifespan of the universe. Insofar as this really would be in principle unverifiable, we have no reason to maintain it is true or false according to the verificationist theory of truth.

Verificationism of this sort is one of a family of anti-realist views. Another example is the view that identifies truth with warranted assertibility. Assertibility, as well as verifiability, has been important in Dummett's work. (See also works of McDowell, e.g., 1976 and Wright, e.g., 1976; 1982; 1992.)

Anti-realism of the Dummettian sort is not a descendant of the coherence theory of truth per se . But in some ways, as Dummett himself has noted, it might be construed as a descendant—perhaps very distant—of idealism. If idealism is the most drastic form of rejection of the independence of mind and world, Dummettian anti-realism is a more modest form, which sees epistemology imprinted in the world, rather than the wholesale embedding of world into mind. At the same time, the idea of truth as warranted assertibility or verifiability reiterates a theme from the pragmatist views of truth we surveyed in section 1.3.

Anti-realist theories of truth, like the realist ones we discussed in section 4.1, can generally make use of the Tarskian apparatus. Convention T, in particular, does not discriminate between realist and anti-realist notions of truth. Likewise, the base clauses of a Tarskian recursive theory are given as disquotation principles, which are neutral between realist and anti-realist understandings of notions like reference. As we saw with the correspondence theory, giving a full account of the nature of truth will generally require more than the Tarskian apparatus itself. How an anti-realist is to explain the basic concepts that go into a Tarskian theory is a delicate matter. As Dummett and Wright have investigated in great detail, it appears that the background logic in which the theory is developed will have to be non-classical.

For more on anti-realism and truth, see the entry on realism .

Many commentators see a close connection between Dummett's anti-realism and the pragmatists' views of truth, in that both put great weight on ideas of verifiability or assertibility. Dummett himself stressed parallels between anti-realism and intuitionism in the philosophy of mathematics.

Another view on truth which returns to pragmatist themes is the ‘internal realism’ of Putnam (1981). There Putnam glosses truth as what would be justified under ideal epistemic conditions. With the pragmatists, Putnam sees the ideal conditions as something which can be approximated, echoing the idea of truth as the end of inquiry.

Putnam is cautious about calling his view ant-realism, preferring the label ‘internal realism’. But he is clear that he sees his view as opposed to realism (‘metaphysical realism’, as he calls it).

5. Deflationism

We began in section 1 with the neo-classical theories, which explained the nature of truth within wider metaphysical systems. We then considered some alternatives in sections 2 and 3, some of which had more modest ontological implications. But we still saw in section 4 that substantial theories of truth tend to imply metaphysical theses, or even embody metaphysical positions.

One long-standing trend in the discussion of truth is to insist that truth really does not carry metaphysical significance at all. It does not, as it has no significance on its own. A number of different ideas have been advanced along these lines, under the general heading of deflationism .

Deflationist ideas appear quite early on, including a well-known argument against correspondence in Frege (1918-19). However, many deflationists take their cue from an idea of Ramsey (1927), often called the equivalence thesis :

⌈   ⌈ φ ⌉ is true ⌉ has the same meaning as φ.

(Ramsey himself takes truth-bearers to be propositions rather than sentences. Glanzberg (2003b) questions whether Ramsey's account of propositions really makes him a deflationist.)

This can be taken as the core of a theory of truth, often called the redundancy theory . The redundancy theory holds that there is no property of truth at all, and appearances of the expression ‘true’ in our sentences are redundant, having no effect on what we express.

The equivalence thesis can also be understood in terms of speech acts rather than meaning:

To assert that ⌈ φ ⌉ is true is just to assert that φ.

This view was advanced by Strawson (1949); Strawson (1950), though Strawson also argues that there are other important aspects of speech acts involving ‘true’ beyond what is asserted. For instance, they may be acts of confirming or granting what someone else said. (Strawson would also object to my making sentences the bearers of truth.)

In either its speech act or meaning form, the redundancy theory argues there is no property of truth. It is commonly noted that the equivalence thesis itself is not enough to sustain the redundancy theory. It merely holds that when truth occurs in the outermost position in a sentence, and the full sentence to which truth is predicated is quoted, then truth is eliminable. What happens in other environments is left to be seen. Modern developments of the redundancy theory include Grover et al. (1975).

The equivalence principle looks familiar: it has something like the form of the Tarski biconditionals discussed in section 2.2. However, it is a stronger principle, which identifies the two sides of the biconditional—either their meanings or the speech acts performed with them. The Tarski biconditionals themselves are simply material biconditionals.

A number of deflationary theories look to the Tarski biconditionals rather than the full equivalence principle. Their key idea is that even if we do not insist on redundancy, we may still hold the following theses:

• For a given language L and every φ in L , the biconditionals ⌈   ⌈ φ ⌉ is true if and only if φ ⌉ hold by definition (or analytically, or trivially, or by stipulation …).
• This is all there is to say about the concept of truth.

We will refer to views which adopt these as minimalist . Officially, this is the name of the view of Horwich (1990), but we will apply it somewhat more widely. (Horwich's view differs in some specific respects from what is presented here, such as predicating truth of propositions, but we believe it is close enough to what is sketched here to justify the name.)

The second thesis, that the Tarski biconditionals are all there is to say about truth, captures something similar to the redundancy theory's view. It comes near to saying that truth is not a property at all; to the extent that truth is a property, there is no more to it than the disquotational pattern of the Tarski biconditionals. As Horwich puts it, there is no substantial underlying metaphysics to truth. And as Soames (1984) stresses, certainly nothing that could ground as far-reaching a view as realism or anti-realism.

If there is no property of truth, or no substantial property of truth, what role does our term ‘true’ play? Deflationists typically note that the truth predicate provides us with a convenient device of disquotation . Such a device allows us to make some useful claims which we could not formulate otherwise, such as the blind ascription ‘The next thing that Bill says will be true’. (For more on blind ascriptions and their relation to deflationism, see Azzouni, 2001.) A predicate obeying the Tarski biconditionals can also be used to express what would otherwise be (potentially) infinite conjunctions or disjunctions, such as the notorious statement of Papal infallibility put ‘Everything the Pope says is true’. (Suggestions like this are found in Leeds, 1978 and Quine, 1970.)

Recognizing these uses for a truth predicate, we might simply think of it as introduced into a language by stipulation . The Tarski biconditionals themselves might be stipulated, as the minimalists envisage. One could also construe the clauses of a recursive Tarskian theory as stipulated. (There are some significant logical differences between these two options. See Halbach (1999) and Ketland (1999) for discussion.) Other deflationists, such as Beall (forthcoming) or Field (1994), might prefer to focus here on rules of inference or rules of use, rather than the Tarski biconditionals themselves.

There are also important connections between deflationist ideas about truth and certain ideas about meaning. These are fundamental to the deflationism of Field (1986); Field (1994), which will be discussed in section 6.3. For an insightful critique of deflationism, see Gupta (1993).

For more on deflationism, see the entry on the deflationary theory of truth .

6. Truth and language

One of the important themes in the literature on truth is its connection to meaning, or more generally, to language. This has proved an important application of ideas about truth, and an important issue in the study of truth itself. This section will consider a number of issues relating truth and language.

There have been many debates in the literature over what the primary bearers of truth are. Candidates typically include beliefs, propositions, sentences, and utterances. We have already seen in section 1 that the classical debates on truth took this issue very seriously, and what sort of theory of truth was viable was often seen to depend on what the bearers of truth are.

In spite of the number of options under discussion, and the significance that has sometimes been placed on the choice, there is an important similarity between candidate truth-bearers. Consider the role of truth-bearers in the correspondence theory, for instance. We have seen versions of it which take beliefs, propositions, or interpreted sentences to be the primary bearers of truth. But all of them rely upon the idea that their truth-bearers represent the world. It is in virtue of representing the world that truth-bearers are able to enter into correspondence relations. Truth-bearers are things which represent, and are true or false depending on whether they correctly represent the facts in the world.

Exactly the same point can be made for the anti-realist theories of truth we saw in section 4.2, though with different accounts of how truth-bearers represent, and what the world contributes. Though it is somewhat more delicate, something similar can be said for coherence theories, which usually take beliefs, or whole systems of beliefs, as the primary truth-bearers. Though a coherence theory will hardly talk of beliefs representing the facts, it is crucial to the coherence theory that beliefs are contentful beliefs of agents, and that they can enter into coherence relations. Noting the complications in interpreting the genuine classical coherence theories, it appears fair to note that this requires truth-bearers to be representations, however the background metaphysics (presumably idealism) understands representation.

Though Tarski works with sentences, the same can be said of his theory. The sentences to which Tarski's theory applies are fully interpreted, and so also are representations. They characterize the world as being some way or another, and this in turn determines whether they are true or false. Indeed, Tarski needs there to be a fact of the matter about whether each sentence is true or false (abstracting away from context dependence), to ensure that the Tarski biconditionals do their job of fixing the extension of ‘is true’. (But note that just what this fact of the matter consists in is left open by the Tarskian apparatus.)

We thus find the usual candidate truth-bearers linked in a tight circle: interpreted sentences, the propositions they express, the belief speakers might hold towards them, and the acts of assertion they might perform with them are all connected by providing representations. This makes them reasonable bearers of truth. For this reason, it seems, contemporary debates on truth have been much less concerned with the issue of truth-bearers than were the classical ones. Some issues remain, of course. Different metaphysical assumptions may place primary weight on some particular node in the circle, and some metaphysical views still challenge the existence of some of the nodes. Perhaps more importantly, different views on the nature of representation itself might cast doubt on the coherence of some of the nodes. Notoriously for instance, Quineans (e.g., Quine, 1960) deny the existence of intensional entities, including propositions. Even so, it increasingly appears doubtful that attention to truth per se will bias us towards one particular primary bearer of truth.

There is a related, but somewhat different point, which is important to understanding the theories we have canvassed.

The neo-classical theories of truth start with truth-bearers which are already understood to be representational, and explain how they get their truth values. But along the way, they often do something more. Take the neo-classical correspondence theory, for instance. This theory, in effect, starts with a view of how propositions represent the world. They do so by having constituents in the world, which are brought together in the right way. There are many complications about the nature of representation, but at a minimum, this tells us what the truth conditions associated with a proposition are. The theory then explains how such truth conditions can lead to the truth value true , by the right fact existing .

Many theories of truth are like the neo-classical correspondence theory in being as much theories of how truth-bearers represent as of how their truth values are fixed. Again, abstracting from some complications about representation, this makes them theories both of truth conditions and truth values . The Tarskian theory of truth can be construed this way too. This can be seen both in the way the Tarski biconditionals are understood, and how a recursive theory of truth is understood. As we explained Convention T in section 2.2, the primary role of a Tarski biconditional of the form ⌈   ⌈ φ ⌉ is true if and only if φ ⌉ is to fix whether φ is in the extension of ‘is true’ or not. But it can also be seen as stating the truth conditions of φ. Both rely on the fact that the unquoted occurrence of φ is an occurrence of an interpreted sentence, which has a truth value, but also provides its truth conditions upon occasions of use.

Likewise, the base clauses of the recursive definition of truth, those for reference and satisfaction, are taken to state the relevant semantic properties of constituents of an interpreted sentence. In discussing Tarski's theory of truth in section 2, we focused on how these determine the truth value of a sentence. But they also show us the truth conditions of a sentence are determined by these semantic properties. For instance, for a simple sentence like ‘Snow is white’, the theory tells us that the sentence is true if the referent of ‘Snow’ satisfies ‘white’. This can be understood as telling us that the truth conditions of ‘Snow is white’ are those conditions in which the referent of ‘Snow’ satisfies the predicate ‘is white’.

As we saw in sections 3 and 4, the Tarskian apparatus is often seen as needing some kind of supplementation to provide a full theory of truth. A full theory of truth conditions will likewise rest on how the Tarskian apparatus is put to use. In particular, just what kinds of conditions those in which the referent of ‘snow’ satisfies the predicate ‘is white’ are will depend on whether we opt for realist or anti-realist theories. The realist option will simply look for the conditions under which the stuff snow bears the property of whiteness; the anti-realist option will look to the conditions under which it can be verified, or asserted with warrant, that snow is white.

There is a broad family of theories of truth which are theories of truth conditions as well as truth values. This family includes the correspondence theory in all its forms—classical and modern. Yet this family is much wider than the correspondence theory, and wider than realist theories of truth more generally. Indeed, virtually all the theories of truth that make contributions to the realism/anti-realism debate are theories of truth conditions. In a slogan, for many approaches to truth, a theory of truth is a theory of truth conditions.

Any theory that provides a substantial account of truth conditions can offer a simple account of truth values: a truth-bearer provides truth conditions, and it is true if and only if the actual way things are is among them. Because of this, any such theory will imply a strong, but very particular, biconditional, close in form to the Tarski biconditionals. It can be made most vivid if we think of propositions as sets of truth conditions. Let p be a proposition, i.e., a set of truth conditions, and let a be the ‘actual world’, the condition that actually obtains. Then we can almost trivially see:

p  is true if and only if  a ∈ p .

This is presumably necessary. But it is important to observe that it is in one respect crucially different from the genuine Tarski biconditionals. It makes no use of a non-quoted sentence, or in fact any sentence at all. It does not have the disquotational character of the Tarski biconditionals.

Though this may look like a principle that deflationists should applaud, it is not. Rather, it shows that deflationists cannot really hold a truth-conditional view of content at all. If they do, then they inter alia have a non-deflationary theory of truth, simply by linking truth value to truth conditions through the above biconditional. It is typical of thoroughgoing deflationist theories to present a non-truth-conditional theory of the contents of sentences: a non-truth-conditional account of what makes truth-bearers representational. We take it this is what is offered, for instance, by the use theory of propositions in Horwich (1990). It is certainly one of the leading ideas of Field (1986); Field (1994), which explore how a conceptual role account of content would ground a deflationist view of truth. Once one has a non-truth-conditional account of content, it is then possible to add a deflationist truth predicate, and use this to give purely deflationist statements of truth conditions. But the starting point must be a non-truth-conditional view of what makes truth-bearers representational.

Both deflationists and anti-realists start with something other than correspondence truth conditions. But whereas an anti-realist will propose a different theory of truth conditions, a deflationists will start with an account of content which is not a theory of truth conditions at all. The deflationist will then propose that the truth predicate, given by the Tarski biconditionals, is an additional device, not for understanding content, but for disquotation. It is a useful device, as we discussed in section 5.3, but it has nothing to do with content. To a deflationist, the representational properties of truth-bearers have nothing to do with truth.

It has been an influential idea, since the seminal work of Davidson (e.g., 1967), to see a Tarskian theory of truth as a theory of meaning. At least, as we have seen, a Tarskian theory can be seen as showing how the truth conditions of a sentence are determined by the semantic properties of its parts. More generally, as we see in much of the work of Davidson and of Dummett (e.g., 1959; 1976; 1983; 1991), giving a theory of truth conditions can be understood as a crucial part of giving a theory of meaning. Thus, any theory of truth that falls into the broad category of those which are theories of truth conditions can be seen as part of a theory of meaning.

A number of commentators on Tarski (e.g., Etchemendy, 1988; Soames, 1984) have observed that the Tarskian apparatus needs to be understood in a particular way to make it suitable for giving a theory of meaning. Tarski's work is often taken to show how to define a truth predicate. If it is so used, then whether or not a sentence is true becomes, in essence, a truth of mathematics. Presumably what truth conditions sentences of a natural language have is a contingent matter, so a truth predicate defined in this way cannot be used to give a theory of meaning for them. But the Tarskian apparatus need not be used just to explicitly define truth. The recursive characterization of truth can be used to state the semantic properties of sentences and their constituents, as a theory of meaning should. In such an application, truth is not taken to be explicitly defined, but rather the truth conditions of sentences are taken to be described. (See Heck, 1997 for more discussion.)

Inspired by Quine (e.g., 1960), Davidson himself is well known for taking a different approach to using a theory of truth as a theory of meaning than is implicit in Field (1972). Whereas a Field-inspired approach is based on a causal account of reference, Davidson (e.g., 1973) proposes a process of radical interpretation in which an interpreter builds a Tarskian theory to interpret a speaker as holding beliefs which are consistent, coherent, and largely true.

This led Davidson (1986) to argue that most of our beliefs are true—a conclusion that squares well with the coherence theory of truth. This is a weaker claim than the neo-classical coherence theory would make. It does not insist that all the members of any coherent set of beliefs are true, or that truth simply consists in being a member of such a coherent set. But all the same, the conclusion that most of our beliefs are true, because their contents are to be understood through a process of radical interpretation which will make them a coherent and rational system, has a clear affinity with the neo-classical coherence theory.

At the same time, Davidson insists that this observation is compatible with a kind of correspondence theory of truth. Indeed, insofar as the Tarskian theory of truth provides a correspondence theory, radical interpretation builds a correspondence theory of truth into its account of content. As we have seen, whether or not this really amounts to a correspondence theory is disputed. As we saw in section 3.1, the Tarskian theory by itself is weaker than the kind of theory proposed by Field (1972); as we saw in section 4.2, it is compatible with anti-realist views of truth. Nonetheless, the Tarskian clauses themselves state more of about the relation of word-to-world than the neo-classical coherence theory anticipated, which leads Davidson to the conclusion that coherence results in correspondence.

For more on Davidson, see the entry on Donald Davidson .

The relation between truth and meaning is not the only place where truth and language relate closely. Another is the idea, also much-stressed in the writings of Dummett (e.g., 1959), of the relation between truth and assertion. Again, it fits into a platitude:

Truth is the aim of assertion.

A person making an assertion, the platitude holds, aims to say something true.

It is easy to cast this platitude in a way that appears false. Surely, many speakers do not aim to say something true. Any speaker who lies does not. Any speaker whose aim is to flatter, or to deceive, aims at something other than truth.

The motivation for the truth-assertion platitude is rather different. It looks at assertion as a practice, in which certain rules are constitutive . As is often noted, the natural parallel here is with games, like chess or baseball, which are defined by certain rules. The platitude holds that it is constitutive of the practice of making assertions that assertions aim at truth. An assertion by its nature presents what it is saying as true, and any assertion which fails to be true is ipso facto liable to criticism, whether or not the person making the assertion themself wished to have said something true or to have lied.

Dummett's original discussion of this idea was partially a criticism of deflationism (in particular, of views of Strawson, 1950). The idea that we fully explain the concept of truth by way of the Tarski biconditionals is challenged by the claim that the truth-assertion platitude is fundamental to truth. As Dummett there put it, what is left out by the Tarski biconditionals, and captured by the truth-assertion platitude, is the point of the concept of truth, or what the concept is used for. (For further discussion, see Glanzberg, 2003a and Wright, 1992.)

Whether or not assertion has such constitutive rules is, of course, controversial. But among those who accept that it does, the place of truth in the constitutive rules is itself controversial. The leading alternative, defended by Williamson (1996), is that knowledge, not truth, is fundamental to the constitutive rules of assertion. Williamson defends an account of assertion based on the rule that one must assert only what one knows.

In 2019 he was awarded the George Orwell Award for Distinguished Contribution to Honesty and Clarity in Public Language. He is the author of Truth in Context: An Essay on Pluralism and Objectivity and True to Life: Why Truth Matters , both published by the MIT Press.

Jeremy Wyatt is Lecturer in Philosophy at the University of Waikato in New Zealand.

Junyeol Kim is Visiting Assistant Professor in Philosophy at the University of Connecticut.

Nathan Kellen is Visiting Assistant Professor in Philosophy at Kansas State University.

The definitive and essential collection of classic and new essays on analytic theories of truth, revised and updated, with seventeen new chapters.

The question “What is truth?” is so philosophical that it can seem rhetorical. Yet truth matters, especially in a “post-truth” society in which lies are tolerated and facts are ignored. If we want to understand why truth matters, we first need to understand what it is. The Nature of Truth offers the definitive collection of classic and contemporary essays on analytic theories of truth. This second edition has been extensively revised and updated, incorporating both historically central readings on truth's nature as well as up-to-the-moment contemporary essays. Seventeen new chapters reflect the current trajectory of research on truth.

Highlights include new essays by Ruth Millikan and Gila Sher on correspondence theories; a new essay on Peirce's theory by Cheryl Misak; seven new essays on deflationism, laying out both theories and critiques; a new essay by Jamin Asay on primitivist theories; and a new defense by Kevin Scharp of his replacement theory, coupled with a probing critique of replacement theories by Alexis Burgess. Classic essays include selections by J. L. Austin, Donald Davidson, William James, W. V. O. Quine, and Alfred Tarski.

Truth, Meaning and Realism: Essays in the Philosophy of Thought

A. C. Grayling, Truth, Meaning and Realism: Essays in the Philosophy of Thought , Continuum, 2007, 173pp., $19.95 (pbk), ISBN 9781847061546.

Reviewed by Alexander Miller, University of Birmingham

This volume is a collection of revised versions of ten essays apparently written in the 1980s or thereabouts, mainly as invited contributions to conferences. As Grayling admits in his preface, "All the papers are of their time". British philosophy in the 1970s and 1980s was dominated by an approach to the debate between realism and antirealism that was associated with Oxford and championed by Michael Dummett, and according to which the key issue was whether the theory of meaning should take as its central concept the notion of truth or the notion of assertibility , with realism favouring the former and antirealism favouring the latter. Much of the book concerns the realism debate conceived in these terms, and although there are also extended discussions of Putnam's twin-earth examples these are mainly in the context of an exchange with David Wiggins. Grayling's essays are thus also very much "of their place" (Oxford) as well as of their time (1980s).

Although in his early works Dummett had defended the idea that assertibility, and not truth, should be the central concept of the theory of meaning, in later work he -- and Crispin Wright -- suggested that antirealism could after all take the notion of truth to be the central notion of the theory of meaning so long as it was an epistemically constrained notion. Given this way of formulating antirealism there is no need to argue that the notion of assertion can be explained in terms that don't presuppose the notion of truth: even the antirealist can admit that it is a platitude that "to assert is to present as true".

In Essay 1, Grayling puts forward a view of assertion that contrasts with the approach of Wright and the later Dummett. Whereas the Wright-later Dummett view sees the aim of assertion as "the presentation of or laying claim to truth" (p.10), Grayling sees it as "the realisation of certain cognitive and practical goals" (ibid.).

Essay 2 proposes a recasting of the debate between realism and antirealism. Grayling suggests that (a) properly understood realism is not a metaphysical but an epistemological thesis: "that the domains or entities to which ontological commitment is made exist independently of knowledge of them" (p.26); and that (b) it is in fact a second-order debate about whether the realistic commitments of ordinary, first-order discourse are literally true or not, and as such has no implications for "logic, linguistic practice, or mundane metaphysics" (p.30). Grayling returns to these issues in Essays 8 and 9.

An alternative to deflationary and indefinabilist conceptions of truth is offered in Essay 3: "The predicate 'is true' is a lazy predicate. It holds a place for more precise predicates, denoting evaluatory properties appropriate to the discourse in which possession of those properties is valued" (p.32). On this view "there are, literally, different kinds of truth, individuated by subject-matter" (p.36). Grayling backs this up in Essay 4 (which, like Essay 3, is a reworked chapter from Grayling's An Introduction to Philosophical Logic , first published in 1982) with a critique of the indefinabilist position Davidson recommends in "The Folly of Trying to Define Truth". This essay also argues that Davidson's "The Coherence Theory of Truth and Knowledge" fails to yield a satisfying account of objectivity: in particular "the principle of charity is questionable beyond its heuristic applications" (p.49).

Putnam's famous "twin-earth" argument appears to some to establish that it is essential to Jones's thinking the thought that someone is drinking water in the next room that there is (or has been) some H 2 0 in Jones's environment. In Essay 5 Grayling considers Wiggins's attempt to fuse this construal of Putnam's insight -- "the extension-involvingness of natural kind terms" (p.62) -- with a Fregean theory distinguishing between the sense and reference of such a term. For Wiggins,

Taking the sense of a name as its mode of presentation of an object means that we have two things … : an object that the name presents, and a way in which it is presented. This latter [is] the 'conception' of the object … 'a body of information' -- typically open-ended and imperfect, and hence rarely if ever condensable into a complete description of the object -- in which the object itself plays a role (p.62),

and something similar holds for natural kind terms: "the sense of a natural kind term is correlative to a recognitional conception that is unspecifiable except as the conception of things like this, that and the other specimens exemplifying the concept that this conception is a conception of" (p.65). Grayling suggests that instead of taking senses to be "correlative" to "conceptions" we should instead identify senses with conceptions: "a term's sense is: an open-ended extensible body of information, possession of which enables speakers to identify the term's reference" (p.69). However, this modified account has consequences for the notion of extension-involving sense:

on the minimum specification given for the grasp of the sense of a concept-word, any concept word which applies to nothing retains its sense because what is known by one who understands it is what would count as an exemplary instance of its application if ever one were offered. (p.74)

In consequence, Wiggins was wrong to take it "that the extension-involvingness constraint ensured the realism of the reality-involvingness he took this to entail" (p.75). Related matters are pursued in Essay 6. Grayling rejects Frege's "strong objectivism" about sense, and argues that since the publicity of sense "is essentially a matter of speakers' mutual constrainings of use", it is best construed in terms of "intersubjective agreement in use" (p.85). This has implications for the externalist arguments of Putnam and Burge. Although it is true that meanings are not in the head of any single speaker, "they are in our heads, collectively understood … meaning is the artefact of intersubjectively constituted conventions governing the use of sounds and marks to communicate, and therefore resides in the language itself" (p.89). This shows -- contra Putnam -- that "facts about the physical environment of language-use are not essential to meaning" (p.89). Grayling reaches this conclusion by reflecting on what he calls an "Explicit Speaker", an idealised speaker who knows everything contained in "some best and latest dictionary [which] pooled a community's knowledge of meanings" (p.87). It follows that

when he [an individual speaker with the linguistic community's best joint knowledge at his disposal] says 'water' he intends to refer to water, that is, H 2 0, or if he lives on twin-earth, then to water on twin-earth, that is, XYZ; and so in either case his grasp of the expression's meaning determines its extension, and the psychological state in which his grasp of the meaning consists is broad. But this is not because it is related, causally or in some other way, to water, but rather to theories of water, because he is speaking in conformity with the best dictionary, that is, with the fullest available knowledge of meaning, in accord with the best current theories held by the linguistic community. (p.88)

Grayling does not consider the obvious reply that a defender of Putnam might give: that a 10 th century English peasant's application of "water" to a sample of XYZ is incorrect, and clearly not because of anything to do with the best current theory held by his linguistic community. Moreover, it appears to beg the question against Putnam to assume that, in the late-20 th century scenario that Grayling is concerned with, facts about the physical environment are not essential to grasp the meanings of some of the expressions that appear in "the best current theories held by the linguistic community".

The "Explicit Speaker" reappears in Essay 7. As Grayling advertises in the preface, this chapter suggests that " point is the driving force in interpretation of implicatures by competent speakers of a natural language" (p.vi), and that "this simple insight reveals certain puzzles to be artefacts of inexplictness" (ibid.). According to Grayling:

An Explicit Speaker of his language is one who so uses it whenever he makes an assertion (and mutatis mutandis for other kinds of utterance) he: (1) expresses his intended meaning as fully as, if not more fully than, his audience needs in the circumstances; (2) expresses his intended meaning as exactly as, if not more exactly than, his audience, etc; and (3) is as epistemically cautious as the circumstances do or might require, if not more so, with respect to the claims made or presupposed by what he says. (p.93)

Grayling proposes to deploy this notion of an Explicit Speaker to shed light on the analogues in natural language of the logical constants, presupposition-failure in uses of the likes of "Jones omitted to turn out the light", the distinction between referential and attributive uses of definite descriptions, and Putnam's use of twin-earth type examples. This chapter is difficult to follow. Although it is titled "Explicit Speaker Theory", and although the expression "Explicit Speaker Theory" is mentioned throughout, Grayling never gives a clear and explicit statement of what the theory actually is. The reader is left to work this out from inexplicit hints. We are told, for example, that according to Explicit Speaker Theory "the crux in meaning is the point, which is to be explained in terms of speakers' intentions to mean something on an occasion" (p.92), that "conventional meaning is to be characterised as the dry residue of speakers' meanings, agreed in the language community under constraints of publicity and stability" (ibid.), that "the meanings of expressions in a language are the agreed dry residue of speakers' meanings" (p.105), and that "what the Explicit Speaker does [when he says "the man whom I take to be drinking champagne is happy tonight"] is what all speakers are enthymematically doing anyway" (p.102). (Grayling does not attempt to explain what it is to do something enthymematically: again, the reader is left to work this out for himself.) In the light of this, readers with less sunny temperaments than the present reviewer are likely to be irritated by comments like "One should surely recognise all this as obvious" (p.100).

That Essay 8 is very much of its time and place is evident from its characterisation as "current orthodoxy" of the view that the realism/antirealism dispute is a debate about whether linguistic understanding is a matter of grasp of epistemically unconstrained truth-conditions or a matter of grasp of assertion conditions. For "current orthodoxy" read "orthodoxy in Oxford in the 1980s", and -- accordingly -- the essay is largely taken up with a discussion of Dummett's analysis of realism as the view that grasp of sentence-meaning is grasp of potentially evidence-transcendent truth-conditions. Grayling argues that rather than attempting in this way to bring all realist/antirealist controversies under one label, we should instead "recognise that they are controversies of different kinds" (p.126). This point is now well-taken -- and indeed defended -- even by philosophers out of the Dummettian stable (cf. Crispin Wright, Truth and Objectivity (Harvard University Press 1992)). However, in contrast to Wright, Grayling argues not that we can develop different realism-relevant considerations that can be brought to bear in different combinations as we move across different discourses, but rather that "we do well to restrict talk of realism to the case where controversy concerns unmetaphorical claims about the knowledge-independent existence of entities or realms of entities -- namely, the 'external world' case" (p.126).

Grayling's argument for this surprising claim is unconvincing. Dummett argues that realism is most fundamentally a semantic thesis, "a doctrine about the sort of thing that makes our statements true when they are true" (quoted by Grayling on p.120), since in some cases a straightforwardly ontological characterisation in terms of the existence of entities is not possible because there are no entities for the realist and antirealist to debate about (Dummett mentions realism about the future and realism about ethics as examples). Grayling argues against this that the semantic thesis is actually less fundamental than realism characterised in metaphysical and epistemological terms on the grounds that Dummett "goes on to unpack the expression 'sort of thing' in a way which shows that its being a semantic thesis comes courtesy of something else" (p.120). To display this Grayling quotes the following passage from Dummett:

the fundamental thesis of realism, so regarded, is that we really do succeed in referring to external objects, existing independently of our knowledge of them, and that the statements we make about them are rendered true or false by an objective reality the constitution of which is, again, independent of our knowledge. (Note that this is not, as Grayling refers to it, on p.55 of Dummett's 1982 "Realism" article, but actually on p.104.)

Grayling takes the reference to external objects in this latter characterisation to show that the semantic characterisation of realism presupposes the ontological characterisation rather than, as Dummett has it, vice versa. It then follows from this that "what we should say about those 'realisms' which are not readily classifiable in terms of entities is, simply, and on Dummett's own reasoning, that they are not realisms" (p.125), and it is this that leads in part to Grayling's restriction of talk of realism to the 'external world' case.

But this is an uncharitable interpretation of Dummett. I take it that what Dummett is saying in the passage quoted by Grayling is actually along the following lines: "the fundamental thesis of realism, so regarded, is that in cases where there is a relevant class of entities whose existence can be a matter of debate , the statements we make about them are rendered true or false by an objective reality the constitution of which is independent of our knowledge, so that in this sense we really do succeed in referring to external objects, existing independently of our knowledge of them; and that in cases where there is no relevant class of entities whose existence can be a matter of debate , the canonical statements of the discourse concerned are rendered true or false by an objective reality the constitution of which is independent of our knowledge". Read in this more charitable way it is clear that the class of entities mentioned is secondary to the mention of knowledge-independent truth, and so there is no implication that talk of realism should be restricted to the "external world" case, so that the way is left open for a Wright-style broadening of the realist/antirealist canvass.

Essay 9 is an extended discussion of McGinn, Nagel and McFetridge on the realism debate, while the final Essay 10 offers some brief reflections on evidence and judgement.

It is not straightforward to appraise this collection, as it is not clear what its target audience is. The various debates have moved on quite a way since Grayling's conference papers were written, and I can't help feeling that they should have been updated and submitted to the rigours of peer-review in the journals before being issued in a collection. To be fair to Grayling, though, he does attempt to pre-empt this kind of worry in his preface, where he points to the "exploratory character" of the essays and says that he "in no case take[s] them to be remotely near a final word on the debates they relate to" (p.v). But I'm not sure that this is enough to get Grayling off the hook. My main problem with the book is not that it is exploratory (there's nothing wrong with that), or that its approach is parochial and somewhat dated, but that the writing style displays some of the worst vices of philosophical writing a la 1980s Oxford, where writing clearly and succinctly appears to be regarded as a mark of superficiality, and where as you get nearer to the nub of an argument, the cruder the stylistic barbarities become. The following example -- of a single sentence! -- from Essay 5 is, unfortunately, not atypical:

Generalising from natural kind terms, we might wish to say that concept words which, in Frege's terminology, refer to empty concepts, can nevertheless be understood, because we can be (so to say) lexically exposed to -- it is more accurate to say: given an understanding of what it would be for something to fall into -- the extensions they would, in better or fuller worlds, have. (p.74)

I'm here reminded of Schopenhauer's comment that "when parentheses are inserted into sentences that have been broken up to accommodate them" the result is "unnecessary and wanton confusion" ( Essays and Aphorisms , trans. R.J. Hollingdale (Penguin 1970), p.207). At any rate, the cause of serious philosophy is not furthered by the poor attempt at Henry James impersonation. Grayling writes:

Too many gifted colleagues publish too little for fear of having every nut and bolt tightened into place; those who venture ideas as if they were letters to friends, trying out a way of thinking about something, and knowing that they will learn from the mistakes they make, do more both for the conversation and themselves thereby. (p.v)

Far be it from me to dictate Grayling's epistolary habits, but if his style in this book is typical of the way he writes to his friends, I'll give his collected correspondence a miss.

Questions about truth and falsity saturate our existence as humans. While we may not always know what is true, we have intuitive ideas of what it would mean for something to be true and work very hard to get “closer” to it. We regularly make claims about what is true seemingly with little to no difficulty. Yet we find ourselves in a constant battle with falsehoods. Our work, our love lives, and even our most cherished recreational times are laden with discovering truth over falsehood. Is that theory true? Is my spouse lying to me? Did the goalie actually deserve that yellow card? So while truth may be an idea we use readily, getting to the truth is surprisingly difficult. Ironically, even definitions of truth that philosophers have developed fall prey to the question, “Are they true?” Still, a definition is as good a place to start as any so here’s one: truth is a statement about the way the world actually is. Let’s explore how good that definition is!

Elusive Truth

Suppose you examine an apple and determine that it’s red, sweet, smooth and crunchy. You might claim this is what the apple  is . Put another way, you’ve made  truth claims  about the apple and seemingly made statements about  real  properties of the apple. But immediate problems arise. Let’s suppose your friend is color blind (this is unknown to you or her) and when she looks at the apple, she says that the apple is a dull greenish color. She also makes a truth claim about the color of the apple but it’s different than your truth claim. What color is the apple?

Well, you might respond, that’s an easy problem to solve. It’s  actually  red because we’ve stipulated that your friend has an anomaly in her truth-gathering equipment (vision) and even though we may not know she has it, the fact that she does means her perception of reality is incorrect. But now let’s suppose  everyone  is color blind and we all see “red” apples as green? Now no one has access to the “real” color of the apple. Again, the response might be that that this is a  knowledge  problem, not a truth problem. The apple really  is  red but we all  believe  it’s green. But notice that the truth of the apple’s color has little role to play in what we believe. No one knows what the truth is and so it plays no role in our epistemology.

The challenge is that our view of truth is very closely tied to our perspective on what is true. This means that in the end, we may be able to come up with a reasonable definition of truth, but if we decide that no one can get to what is true (that is,  know  truth), what good is the definition? Even more problematic is that our perspective will even influence our ability to come up with a definition! These are no small concerns and we’ll explore some responses below.

Some Preliminaries

Epistemologists (people who study truth, belief and knowledge) use the following concepts as the framework for their study of truth.

Propositions . A common technical definition of a proposition (credited to Peter van Inwagen) is “a non-linguistic bearer of truth value.” A proposition is a representation of the world or a way the world could possibly be and propositions are either true or false. Propositions are different than sentences . Sentences are symbolic, linguistic representations of propositions. Okay, that’s all very technical. What does it mean?

Let’s take the sentence, “The moon has craters.” This is an English sentence that supposedly states some fact about the world or reality. Because it’s in English, we say it’s “linguistic” or language-based. Specifically, we can describe the sentence’s properties as having four words and 17 letters, it’s in the English language written in 11 point font and it’s black. I could write the same sentence like this:

The moon has craters .

This one still has the same number of words and letters and it’s in English. But it is in 18 point font and is written in blue. Now let’s take this sentence, “La luna tiene cráteres.” This sentence has four words but 19 letters. It’s written in 11 point font and is black but it’s Spanish. What do all three sentences have in common? Well, they all express the same idea or meaning and we could say the same “truth.” We could express the same idea in Swahili, semaphore, Morse code, or any other symbolic system that conveys meaning.

Notice that the symbols themselves are neither true nor false. The meaning the sentences represent is either true or false. This “other thing” the sentences represent are propositions. Put another way, the common property true of all sentences that express the same truth is what philosophers call the propositional content of the sentences or “the proposition.” Now we can better understand the idea behind “non-linguistic bearer of truth value.” Propositions are non-linguistic because they aren’t written or spoken in a language. They bear truth because they are the things that are true or false. This is what allows them to be expressed or “exemplified” in a variety of different symbolic systems like language-based sentences. When it comes to understanding truth, many philosophers believe propositions are at the center.

Belief . Beliefs are things (at least) people have. They don’t exist outside the mind. Some philosophers say beliefs are “dispositional.” That is, they incline a person to behave in a way as if the thing they believe is true. So a belief, simply, is a proposition that a person accepts as representing the way the world actually is. Beliefs can be about false propositions and thus be “wrong” because the person accepts them as true. This is a critical distinction. While a proposition has to be true or false, beliefs can be about true or false propositions even though a person always accepts them as true.

Some philosophers attempt to define truth “mind-independently.” That means, they want to come up with a definition that doesn’t depend on whether humans can actually believe or know what is true. Truth is viewed as independent of our minds and they seek a definition of it that captures this. Other philosophers have developed theories that keep people at the center. That is, truth and belief are considered together and are inseparable. I will try to make the relevance of the “epistemic” vs. “independent” views of truth relevant below.

Knowledge . Knowledge is belief in a true proposition that a person is justified in holding as true. The conditions under which a person is justified is somewhat complex and there are many theories about when the conditions are met. Theories of knowledge attempt to describe when a person is in a “right” cognitive relationship with true propositions. I describe some theories of knowledge and some of the challenges in understanding when a person knows in an article for Philosophy News called “ What is Knowledge? “

Common Definitions

The coherence view of truth.

The main idea behind this view is that a belief is true if it “coheres” or is consistent with other things a person believes. For example, a fact a person believes, say “grass is green” is true if that belief is consistent with other things the person believes like the definition of green and whether grass exists and the like. It also depends on the interpretation of the main terms in those other beliefs. Suppose you’ve always lived in a region covered with snow and never saw grass or formed beliefs about this strange plant life. The claim “grass is green” would not cohere with other beliefs because you have no beliefs that include the concept “grass.” The claim, “grass is green” would be nonsense because it contains a nonsensical term. You’ve never formed a belief about grass so there’s nothing for this new belief to cohere with.

As you can see, coherence theories typically are described in terms of beliefs. This puts coherence theories in the “epistemic” view of truth. This is because, coherence theorists claim, we can only ground a given belief on other things we believe. We cannot “stand outside” our own belief system to compare our beliefs with the actual world. If I believe Booth shot Lincoln, I can only determine if that belief is truth based on other things I believe like “Wikipedia provides accurate information” or “My professor knows history and communicates it well” or “Uncle John sure was a scoundrel.” These are other beliefs and serve as a basis for my original belief.

Thus truth is essentially epistemic since any other model requires a type of access to the “real world” we simply can’t have. As philosopher Donald Davidson describes the situation, “If coherence is a test of truth, there is a direct connection with epistemology, for we have reason to believe many of our beliefs cohere with many others, and in that case we have reason to believe many of our beliefs are true.” (Davidson, 2000)

The Correspondence Theory of Truth

Arguably the more widely-held view of truth, philosophers who argue for the correspondence theory hold that there is a world external to our beliefs that is somehow accessible to the human mind. Specifically, correspondence theorists hold that there are a set of “truth-bearing” representations (propositions) about the world that align to or correspond with reality. When a proposition aligns to the way the world actually is, the proposition is said to be true. Truth, on this view, is that correspondence relation.

Take this proposition: “The Seattle Seahawks won Super Bowl 48 in 2014.” The proposition is true if in fact the Seahawks did win super Bowl 48 in 2014 (they did) and false if they didn’t.

The correspondence theory only lays out the condition for truth in terms of propositions and the way the world actually is. This definition does not involve beliefs that people have. Propositions are true or false regardless of whether anyone believes them. Just think of a proposition as a way the world possibly could be: “The Seahawks won Super Bowl 48” or “The Seahawks lost Super Bowl 48” — both propositions possibly are true. True propositions are those that correspond to what actually happened.

Postmodernism

Postmodern thought covers a wide theoretical area but informs modern epistemology particularly when it comes to truth. In simple terms, postmodernists describe truth not as a relationship outside of the human mind that we can align belief to but as a product of belief. We never access reality because we can never get outside our own beliefs to do so. Our beliefs function as filters that keep reality (if such a thing exists) beyond us. Since we can never access reality, it does no good to describe knowledge or truth in terms of reality because there’s nothing we can actually say about reality that’s meaningful. Truth then is constructed by what we perceive and ultimately believe.

Immanuel Kant

I’m inclined to earmark the foundation of postmodern thought with the work of Immanuel Kant, specifically with his work The Critique of Pure Reason . In my view, Kant was at the gateway of postmodern thought. He wasn’t a postmodernist himself but provided the framework for what later developed.

Kant makes a foundational distinction between the “objects” of subjective experience and the “objects” of “reality.” He labels the former phenomena and that latter noumena . The noumena for Kant are things in themselves ( ding an sich ). These exist outside of and separate from the mind. These are what we might call “reality” or actual states of affairs similar to what we saw in the correspondence theory above. But for Kant, the noumena are entirely unknowable in and of themselves . However, the noumena give rise to the phenomena or are the occasion by which we come to know the phenomena.

The phenomena make up the world we know, the world “for us” ( für uns ). This is the world of rocks, trees, books, tables, and any other objects we access through the five senses. This is the world of our experience. This world, however, does not exist apart from our experience. It is essentially experiential. Kant expressed this idea as follows: the world as we know it is “phenomenally real but transcendentally ideal.” That is, objects that we believe exist in the world are a “real” part of our subjective experience but they do not exist apart from that subjective experience and don’t transcend the beliefs we have. The noumena are “transcendentally real” or they exist in and of themselves but are never experienced directly or even indirectly.

The noumena are given form and shape by what Kant described as categories of the mind and this ‘ordering’ gives rise to phenomenal objects. This is where it relates to truth: phenomenal objects are not analogues, copies, representations or any such thing of the noumena. The noumena gives rise to the phenomena but in no way resembles them. Scholars have spent countless hours trying to understand Kant on this point since it seems like the mind interacts with the noumena in some way. But Kant does seem to be clear that the mind never experiences the noumena directly and the phenomena in no way represents the noumena.

We can now see the beginnings of postmodern thought. If we understand the noumena as “reality” and the phenomena as the world we experience, we can see that we never get past our experience to reality itself. It’s not like a photograph which represents a person and by seeing the photograph we can have some understanding of what the “real person” actually looks like. Rather (to use an admittedly clumsy example) it’s like being in love. We can readily have the experience and we know the brain is involved but we have no idea how it works. By experiencing the euphoria of being in love, we learn nothing about how the brain works.

On this view then, what is truth? Abstractly we might say truth is found in the noumena since that’s reality. But postmodernists have taken Kant’s idea further and argued that since we can’t say anything about the noumena, why bother with them at all? Kant didn’t provided a good reason to believe the noumena exist but seems to have asserted their existence because, after all, something was needed to give rise to the phenomena. Postmodernists just get rid of this extra baggage and focus solely on what we experience.

Perspective and Truth

Further, everyone’s experience of the world is a bit different–we all have different life experiences, background beliefs, personalities and dispositions, and even genetics that shape our view of the world. This makes it impossible, say the postmodernists, to declare an “absolute truth” about much of anything since our view of the world is a product of our individual perspective. Some say that our worldview makes up a set of lenses or a filter through which we interpret everything and we can’t remove those lenses. Interpretation and perspective are key ideas in postmodern thought and are contrasted with “simple seeing” or a purely objective view of reality. Postmodernists think simple seeing is impossible.

We can see some similarities here to the coherence theory of truth with its web of interconnected and mutually supported beliefs. On the coherence theory, coherence among beliefs gives us reason to hold that what we believe corresponds to some external reality. In postmodernism there is nothing for our beliefs to correspond to or if there is, our beliefs never get beyond the limits of our minds to enable us to make any claims about that reality.

Community Agreement

Postmodernism differs from radical subjectivism (truth is centered only in what an individual experiences) by allowing that there might be “community agreement” for some truth claims. The idea is that two or more people may be able to agree on a particular truth claim and form a shared agreement. To be clear, the perspective is not true because they agree it maps or corresponds to reality. But since the members of the group all agree that a given proposition or argument works in some practical way, or has explanatory power (seems to explain some particular thing), or has strong intuitive force for them, they can use this shared agreement to form a knowledge community.

When you think about it, this is how things tend to work. A scientist discovers something she takes to be true and writes a paper explaining why she thinks it’s true. Other scientists read her paper, run their own experiments and either validate her claims or are unable to invalidate her claims. These scientists then declare the theory “valid” or “significant” or give it some other stamp of approval. In most cases, this does not mean the theory is immune from falsification or to being disproved–it’s not absolute. It just means that the majority of the scientific community that have studied the theory agree that it’s true given what they currently understand. This shared agreement creates a communal “truth” for those scientists. This is what led Richard Rorty to state the oft-quoted phrase, “Truth is what my colleagues will let me get away with.”

What is Truth?

So we have some theories but it seems we’re no closer to answering our question. Which theory is true? Kant surely was on to something when he claimed that we have to start with our beliefs if for no other reason than that it seems impossible to deny. Any “reality” statement recast as a belief statement seems to be an exercise that adds specificity. But the reverse isn’t truth. For example, the claim, “Harvard’s library contains a copy of the Oxford English Dictionary” can readily be recast as “I believe Harvard’s library contains a copy of the Oxford English Dictionary” we naturally take this second statement as adding clarity to what we meant by the first. But if we restate, “I believe Harvard’s library contains a copy of the Oxford English Dictionary” as “Harvard’s library contains a copy of the Oxford English Dictionary” we lose the meaning of the first statement. We can see this if we add the additional phrase, “but I don’t believe it.” The “reality” statement is supposed to make a claim about the Harvard library but without the belief qualifier, we have no way to access its truth condition. In other words, the only way to get at the world is through our minds and our minds are filled with beliefs and only beliefs. If you object and claim that minds can be filled with true propositions, isn’t that something you believe?

So the question then becomes, do our beliefs correspond to the way the world actually is—do we access the noumena—or do we filter everything such that our beliefs do not correspond

Practical Concerns

Philosophers are supposed to love wisdom and wisdom is more oriented towards the practical than the theoretical. This article has been largely about a theoretical view of truth so how do we apply it? Most people don’t spend a whole lot of time thinking about what truth is but tend to get by in the world without that understanding. That’s probably because the world seems to impose itself on us rather than being subject to some theory we might come up with about how it has to operate. We all need food, water and shelter, meaning, friendship, and some purpose that compels us to get out of bed in the morning. This is a kind of practical truth that is not subject to the fluidity of philosophical theory.

Even so, we all contend with truth claims on a daily basis. We have to make decisions about what matters. Maybe you’re deeply concerned about politics and what politicians are claiming or what policy should be supported or overturned. Perhaps you care about which athlete should be traded or whether you should eat meat or support the goods produced by a large corporation. You may want to know if God exists and if so, which one. You probably care what your friends or loved ones are saying and whether you can count on them or invest in their relationship. In each of these cases, you will apply a theory of truth whether you realize it or not and so a little reflection on what you think about truth will be important.

Your view of truth will impact how you show up at work and impacts the decisions you make about how to raise your children or deal with a conflict. For example, suppose you’re faced with a complex question at work about something you’re responsible for. You need to decide whether to ship a product or do more testing. If you’re a postmodernist, your worldview may cause you to be more tentative about the conclusions you’re drawing about the product’s readiness because you understand that your interpretation of the facts you have about the product may be clouded by your own background beliefs. Because of this, you may seek more input or seek more consensus before you move forward. You may find yourself silently scoffing at your boss who makes absolute decisions about the “right” way to move forward because you believe there is no “right” way to do much of anything. There’s just each person’s interpretation of what is right and whoever has the loudest voice or exerts the most force wins.

An engineer may disagree here. She may argue, as an example, that there is a “right” way to build an airplane and a lot of wrong ways and years of aviation history documents both. Here is an instance where the world imposes itself on us: airplanes built with wings and that follow specific rules of aerodynamics fly and machines that don’t follow those “laws” don’t. Further most of us would rather fly in airplanes built by engineers that have more of a correspondence view of truth. We want to believe that the engineers that built the plane we’re in understand aerodynamics and built a plane that corresponds with the propositions that make up the laws of aerodynamics.

Your view of truth matters. You may be a correspondence theorist when it comes to airplanes but a postmodernist when it comes to ethics or politics. But why hold different views of truth for different aspects of your life? This is where a theory comes in. As you reflect on the problems posed by airplanes and ethics, the readiness of your product to be delivered to consumers and the readiness of your child to be loosed upon the world, about what makes you happy and about your responsibility to your fellow man, you will develop a theory of truth that will help you navigate these situations with more clarity and consistency.

• Postmodernism

The pursuit of truth is often thought to be "intrinsically" valuable. Scientists and philosophers, who eschew religious rationales for their life's work, take the pursuit of truth to be obviously a worthwhile enterprise. But what's so great about truth? Sure, it's good to know what's for lunch, or the nature of the disease that plagues you, but is there any intrinsic or instrumental value in knowing how far away the farthest stars are? Or whether Milton's greatest works were written while he had a headache? Or what the next layer of basic particles are like? Truth telling on Philosophy Talk with Simon Blackburn, author of  Truth: A Guide.

Listening Notes

What's so valuable about truth? Ken thinks that the value of truth is obvious. Having true beliefs help us act so as to satisfy our desires. John points out that sometimes the truth can be harmful, such as knowing where drugs are being sold. There are a lot of truths that are irrelevant or trivial. There are also depressing truths. Ken thinks that you can't separate truth from believing because when we believe something, we take it to be true. Ken introduces the guest, Simon Blackburn, professor at Cambridge. John asks Blackburn to explain the nature of truth. Blackburn explains minimalism about truth, which says that there is no general answer about truth. The correspondence theory of truth says that there is some fact that makes a judgment true. However, there is no higher-order verification of this judgment. Another view is the pragmatist theory which says that the truth is valuable because it is useful.

What is the postmodernists' problem with truth? Blackburn says that the general idea goes back to Nietzsche and it is that our judgments and beliefs are formed and shaped by various forces beyond our control. Ken says that we would get around this if we had some method of tracking the truth. Blackburn says that the correspondence theory of truth works great when we are working with a straightforward representation of the world that we understand. How do we discern truth from falsehood? Blackburn thinks that is a skill that requires a lot of practice.

Some truths hurt us and some falsehoods are comforting. Should we always seek out truth for its own sake? There are a bunch of useless truths, such as the composition of dirt on Mars. Blackburn thinks that the useful falsehood is a hard idea to dispel. According to many psychologists, most people think they are about 15% smarter or good-looking than they actually are, and that keeps many people from being depressed. Nietzsche was moved to his relativism by perspectivism, which says that we view the world from our own perspective. Blackburn doesn't think that perspectivism leads to relativism because the visual metaphor breaks down.

It is I natural to understand that academic work requires time, effort and focus. Writing essays has often been challenging for me due to the need for research, structuring the material, and clear argumentation. However, there is always a way out. Using nursing school papers that I found from a trusted resource helped me overcome many challenges. Agree, the documents of the nursing school contain various reports, statistical data, documents on educational and methodological work, career guidance programs, as well as materials related to professional practice and the training of future medical specialists, therefore, in my opinion, the expert who helped me understand all the intricacies of academic work gave me the necessary knowledge base that I needed in my future work.

Of Truth, by Francis Bacon

"Of Truth" is the opening essay in the final edition of the philosopher, statesman and jurist  Francis Bacon 's "Essays or Counsels, Civil and Moral" (1625). In this essay, as associate professor of philosophy Svetozar Minkov points out, Bacon addresses the question of "whether it is worse to lie to others or to oneself--to possess truth (and lie, when necessary, to others) or to think one possesses the truth but be mistaken and hence unintentionally convey falsehoods to both oneself and to others" ("Francis Bacon's 'Inquiry Touching Human Nature,'" 2010). In "Of Truth," Bacon argues that people have a natural inclination to lie to others: "a natural though corrupt love, of the lie itself."

"What is truth?" said jesting Pilate, and would not stay for an answer. Certainly, there be that delight in giddiness, and count it a bondage to fix a belief, affecting free-will in thinking as well as in acting. And though the sects of philosophers of that kind be gone, yet there remain certain discoursing wits which are of the same veins, though there be not so much blood in them as was in those of the ancients. But it is not only the difficulty and labor which men take in finding out of truth, nor again that when it is found it imposeth upon men's thoughts, that doth bring lies in favor, but a natural though corrupt love of the lie itself. One of the later school of the Grecians examineth the matter, and is at a stand to think what should be in it, that men should love lies where neither they make for pleasure, as with poets, nor for advantage, as with the merchant; but for the lie's sake. But I cannot tell: this same truth is a naked and open daylight that doth not show the masques and mummeries and triumphs of the world half so stately and daintily as candle-lights. Truth may perhaps come to the price of a pearl that showeth best by day; but it will not rise to the price of a diamond or carbuncle, that showeth best in varied lights. A mixture of a lie doth ever add pleasure. Doth any man doubt that if there were taken out of men's minds vain opinions, flattering hopes, false valuations, imaginations as one would, and the like, but it would leave the minds of a number of men poor shrunken things, full of melancholy and indisposition, and unpleasing to themselves? One of the fathers, in great severity, called poesy vinum daemonum [the wine of devils] because it filleth the imagination, and yet it is but with the shadow of a lie. But it is not the lie that passeth through the mind, but the lie that sinketh in and settleth in it that doth the hurt, such as we spake of before. But howsoever these things are thus in men's depraved judgments and affections, yet truth, which only doth judge itself, teacheth that the inquiry of truth, which is the love-making or wooing of it; the knowledge of truth, which is the presence of it; and the belief of truth, which is the enjoying of it, is the sovereign good of human nature. The first creature of God in the works of the days was the light of the sense; the last was the light of reason; and his Sabbath work ever since is the illumination of his spirit. First he breathed light upon the face of the matter, or chaos; then he breathed light into the face of man; and still he breatheth and inspireth light into the face of his chosen. The poet that beautified the sect that was otherwise inferior to the rest, saith yet excellently well, "It is a pleasure to stand upon the shore, and to see ships tossed upon the sea; a pleasure to stand in the window of a castle, and to see a battle and the adventures thereof below; but no pleasure is comparable to the standing upon the vantage ground of truth (a hill not to be commanded, and where the air is always clear and serene), and to see the errors and wanderings and mists and tempests in the vale below"*; so always that this prospect be with pity, and not with swelling or pride. Certainly it is heaven upon earth to have a man's mind move in charity, rest in providence, and turn upon the poles of truth.

To pass from theological and philosophical truth to the truth of civil business: it will be acknowledged, even by those that practice it not, that clear and round dealing is the honor of man's nature, and that mixture of falsehood is like alloy in coin of gold and silver, which may make the metal work the better, but it embaseth it. For these winding and crooked courses are the goings of the serpent, which goeth basely upon the belly and not upon the feet. There is no vice that doth so cover a man with shame as to be found false and perfidious; and therefore Montaigne saith prettily, when he inquired the reason why the word of the lie should be such a disgrace and such an odious charge. Saith he, "If it be well weighed, to say that a man lieth, is as much as to say that he is brave towards God, and a coward towards man." For a lie faces God, and shrinks from man. Surely the wickedness of falsehood and breach of faith cannot possibly be so highly expressed as in that it shall be the last peal to call the judgments of God upon the generations of men: it being foretold that when Christ cometh, "He shall not find faith upon the earth."

*Bacon's paraphrase of the opening lines of Book II of "On the Nature of Things" by Roman poet Titus Lucretius Carus.

Needs, Values, Truth: Essays in the Philosophy of Value

• Cite Icon Cite
• Permissions Icon Permissions

Needs, Values, Truth brings together of some of the most important and influential writings by a leading contemporary philosopher, David Wiggins; they are drawn from twenty-five years of his work in the broad area of the philosophy of value. The author passes to and fro between problems of ethics, meta-ethics, philosophy of mind, and philosophy of logic and language. The following themes are prominent: the elucidation of the ideas of truth, objectivity, subjectivity and intersubjectivity the scope and limits of the attribution of the status of plain truth among the judgements of morals, politics and aesthetics the compatibility of moral cognitivism both with criticism and with a 'no-foundations' view of morals, politics and aesthetics the part played in the fixation of the sense of evaluative language by the antecedent possibility of agreement not only in judgements but also (the Humean addendum) in sentiments the philosophical ineliminability of explanations that explain a subject's thought by vindicating it, and the indispensability of evaluative and subjective categories to such vindications the irreplaceability and irreducibility for practical or valuational thinking of such ideas as those of need, self and metaphysical freedom. For this third edition the author has added a new essay on incommensurability, in addition to making minor revisions to the existing text. The volume will stand as a definitive summation of his work in this area.

1.1 What Is Philosophy?

Learning objectives.

By the end of this section, you will be able to:

• Identify sages (early philosophers) across historical traditions.
• Explain the connection between ancient philosophy and the origin of the sciences.
• Describe philosophy as a discipline that makes coherent sense of a whole.
• Summarize the broad and diverse origins of philosophy.

It is difficult to define philosophy. In fact, to do so is itself a philosophical activity, since philosophers are attempting to gain the broadest and most fundamental conception of the world as it exists. The world includes nature, consciousness, morality, beauty, and social organizations. So the content available for philosophy is both broad and deep. Because of its very nature, philosophy considers a range of subjects, and philosophers cannot automatically rule anything out. Whereas other disciplines allow for basic assumptions, philosophers cannot be bound by such assumptions. This open-endedness makes philosophy a somewhat awkward and confusing subject for students. There are no easy answers to the questions of what philosophy studies or how one does philosophy. Nevertheless, in this chapter, we can make some progress on these questions by (1) looking at past examples of philosophers, (2) considering one compelling definition of philosophy, and (3) looking at the way academic philosophers today actually practice philosophy.

Historical Origins of Philosophy

One way to begin to understand philosophy is to look at its history. The historical origins of philosophical thinking and exploration vary around the globe. The word philosophy derives from ancient Greek, in which the philosopher is a lover or pursuer ( philia ) of wisdom ( sophia ). But the earliest Greek philosophers were not known as philosophers; they were simply known as sages . The sage tradition provides an early glimpse of philosophical thought in action. Sages are sometimes associated with mathematical and scientific discoveries and at other times with their political impact. What unites these figures is that they demonstrate a willingness to be skeptical of traditions, a curiosity about the natural world and our place in it, and a commitment to applying reason to understand nature, human nature, and society better. The overview of the sage tradition that follows will give you a taste of philosophy’s broad ambitions as well as its focus on complex relations between different areas of human knowledge. There are some examples of women who made contributions to philosophy and the sage tradition in Greece, India, and China, but these were patriarchal societies that did not provide many opportunities for women to participate in philosophical and political discussions.

The Sages of India, China, Africa, and Greece

In classical Indian philosophy and religion, sages play a central role in both religious mythology and in the practice of passing down teaching and instruction through generations. The Seven Sages, or Saptarishi (seven rishis in the Sanskrit language), play an important role in sanatana dharma , the eternal duties that have come to be identified with Hinduism but that predate the establishment of the religion. The Seven Sages are partially considered wise men and are said to be the authors of the ancient Indian texts known as the Vedas . But they are partly mythic figures as well, who are said to have descended from the gods and whose reincarnation marks the passing of each age of Manu (age of man or epoch of humanity). The rishis tended to live monastic lives, and together they are thought of as the spiritual and practical forerunners of Indian gurus or teachers, even up to today. They derive their wisdom, in part, from spiritual forces, but also from tapas , or the meditative, ascetic, and spiritual practices they perform to gain control over their bodies and minds. The stories of the rishis are part of the teachings that constitute spiritual and philosophical practice in contemporary Hinduism.

Figure 1.2 depicts a scene from the Matsya Purana, where Manu, the first man whose succession marks the prehistorical ages of Earth, sits with the Seven Sages in a boat to protect them from a mythic flood that is said to have submerged the world. The king of serpents guides the boat, which is said to have also contained seeds, plants, and animals saved by Manu from the flood.

Despite the fact that classical Indian culture is patriarchal, women figures play an important role in the earliest writings of the Vedic tradition (the classical Indian religious and philosophical tradition). These women figures are partly connected to the Indian conception of the fundamental forces of nature—energy, ability, strength, effort, and power—as feminine. This aspect of God was thought to be present at the creation of the world. The Rig Veda, the oldest Vedic writings, contains hymns that tell the story of Ghosha, a daughter of Rishi Kakshivan, who had a debilitating skin condition (probably leprosy) but devoted herself to spiritual practices to learn how to heal herself and eventually marry. Another woman, Maitreyi, is said to have married the Rishi Yajnavalkya (himself a god who was cast into mortality by a rival) for the purpose of continuing her spiritual training. She was a devoted ascetic and is said to have composed 10 of the hymns in the Rig Veda. Additionally, there is a famous dialogue between Maitreyi and Yajnavalkya in the Upanishads (another early, foundational collection of texts in the Vedic tradition) about attachment to material possessions, which cannot give a person happiness, and the achievement of ultimate bliss through knowledge of the Absolute (God).

Another woman sage named Gargi also participates in a celebrated dialogue with Yajnavalkya on natural philosophy and the fundamental elements and forces of the universe. Gargi is characterized as one of the most knowledgeable sages on the topic, though she ultimately concedes that Yajnavalkya has greater knowledge. In these brief episodes, these ancient Indian texts record instances of key women who attained a level of enlightenment and learning similar to their male counterparts. Unfortunately, this early equality between the sexes did not last. Over time Indian culture became more patriarchal, confining women to a dependent and subservient role. Perhaps the most dramatic and cruel example of the effects of Indian patriarchy was the ritual practice of sati , in which a widow would sometimes immolate herself, partly in recognition of the “fact” that following the death of her husband, her current life on Earth served no further purpose (Rout 2016). Neither a widow’s in-laws nor society recognized her value.

In similar fashion to the Indian tradition, the sage ( sheng ) tradition is important for Chinese philosophy . Confucius , one of the greatest Chinese writers, often refers to ancient sages, emphasizing their importance for their discovery of technical skills essential to human civilization, for their role as rulers and wise leaders, and for their wisdom. This emphasis is in alignment with the Confucian appeal to a well-ordered state under the guidance of a “ philosopher-king .” This point of view can be seen in early sage figures identified by one of the greatest classical authors in the Chinese tradition, as the “Nest Builder” and “Fire Maker” or, in another case, the “Flood Controller.” These names identify wise individuals with early technological discoveries. The Book of Changes , a classical Chinese text, identifies the Five (mythic) Emperors as sages, including Yao and Shun, who are said to have built canoes and oars, attached carts to oxen, built double gates for defense, and fashioned bows and arrows (Cheng 1983). Emperor Shun is also said to have ruled during the time of a great flood, when all of China was submerged. Yü is credited with having saved civilization by building canals and dams.

These figures are praised not only for their political wisdom and long rule, but also for their filial piety and devotion to work. For instance, Mencius, a Confucian philosopher, relates a story of Shun’s care for his blind father and wicked stepmother, while Yü is praised for his selfless devotion to work. In these ways, the Chinese philosophical traditions, such as Confucianism and Mohism, associate key values of their philosophical enterprises with the great sages of their history. Whether the sages were, in fact, actual people or, as many scholars have concluded, mythical forebearers, they possessed the essential human virtue of listening and responding to divine voices. This attribute can be inferred from the Chinese script for sheng , which bears the symbol of an ear as a prominent feature. So the sage is one who listens to insight from the heavens and then is capable of sharing that wisdom or acting upon it to the benefit of his society (Cheng 1983). This idea is similar to one found in the Indian tradition, where the most important texts, the Vedas, are known as shruti , or works that were heard through divine revelation and only later written down.

Although Confucianism is a venerable world philosophy, it is also highly patriarchal and resulted in the widespread subordination of women. The position of women in China began to change only after the Communist Revolution (1945–1952). While some accounts of Confucianism characterize men and women as emblematic of two opposing forces in the natural world, the Yin and Yang, this view of the sexes developed over time and was not consistently applied. Chinese women did see a measure of independence and freedom with the influence of Buddhism and Daoism, each of which had a more liberal view of the role of women (Adler 2006).

A detailed and important study of the sage tradition in Africa is provided by Henry Odera Oruka (1990), who makes the case that prominent folk sages in African tribal history developed complex philosophical ideas. Oruka interviewed tribal Africans identified by their communities as sages, and he recorded their sayings and ideas, confining himself to those sayings that demonstrated “a rational method of inquiry into the real nature of things” (Oruka 1990, 150). He recognized a tension in what made these sages philosophically interesting: they articulated the received wisdom of their tradition and culture while at the same time maintaining a critical distance from that culture, seeking a rational justification for the beliefs held by the culture.

Connections

The chapter on the early history of philosophy covers this topic in greater detail.

Among the ancient Greeks, it is common to identify seven sages. The best-known account is provided by Diogenes Laërtius, whose text Lives and Opinions of Eminent Philosophers is a canonical resource on early Greek philosophy. The first and most important sage is Thales of Miletus . Thales traveled to Egypt to study with the Egyptian priests, where he became one of the first Greeks to learn astronomy. He is known for bringing back to Greece knowledge of the calendar, dividing the year into 365 days, tracking the progress of the sun from solstice to solstice, and—somewhat dramatically—predicting a solar eclipse in 585 BCE. The eclipse occurred on the day of a battle between the Medes and Lydians. It is possible that Thales used knowledge of Babylonian astronomical records to guess the year and location of the eclipse. This mathematical and astronomical feat is one of Thales’s several claims to sagacity. In addition, he is said to have calculated the height of the pyramids using the basic geometry of similar triangles and measuring shadows at a certain time of day. He is also reported to have predicted a particularly good year for olives: he bought up all the olive presses and then made a fortune selling those presses to farmers wanting to turn their olives into oil. Together, these scientific and technical achievements suggest that at least part of Thales’s wisdom can be attributed to a very practical, scientific, and mathematical knowledge of the natural world. If that were all Thales was known for, he might be called the first scientist or engineer. But he also made more basic claims about the nature and composition of the universe; for instance, he claimed that all matter was fundamentally made of up water. He also argued that everything that moved on its own possessed a soul and that the soul itself was immortal. These claims demonstrate a concern about the fundamental nature of reality.

Another of the seven sages was Solon , a famed political leader. He introduced the “Law of Release” to Athens, which cancelled all personal debts and freed indentured servants, or “debt-slaves” who had been consigned to service based on a personal debt they were unable to repay. In addition, he established a constitutional government in Athens with a representative body, a procedure for taxation, and a series of economic reforms. He was widely admired as a political leader but voluntarily stepped down so that he would not become a tyrant. He was finally forced to flee Athens when he was unable to persuade the members of the Assembly (the ruling body) to resist the rising tyranny of one of his relatives, Pisistratus. When he arrived in exile, he was reportedly asked whom he considered to be happy, to which he replied, “One ought to count no man happy until he is dead.” Aristotle interpreted this statement to mean that happiness was not a momentary experience, but a quality reflective of someone’s entire life.

Beginnings of Natural Philosophy

The sage tradition is a largely prehistoric tradition that provides a narrative about how intellect, wisdom, piety, and virtue led to the innovations central to flourishing of ancient civilizations. Particularly in Greece, the sage tradition blends into a period of natural philosophy, where ancient scientists or philosophers try to explain nature using rational methods. Several of the early Greek schools of philosophy were centered on their respective views of nature. Followers of Thales, known as the Milesians , were particularly interested in the underlying causes of natural change. Why does water turn to ice? What happens when winter passes into spring? Why does it seem like the stars and planets orbit Earth in predictable patterns? From Aristotle we know that Thales thought there was a difference between material elements that participate in change and elements that contain their own source of motion. This early use of the term element did not have the same meaning as the scientific meaning of the word today in a field like chemistry. But Thales thought material elements bear some fundamental connection to water in that they have the capacity to move and alter their state. By contrast, other elements had their own internal source of motion, of which he cites the magnet and amber (which exhibits forces of static electricity when rubbed against other materials). He said that these elements have “soul.” This notion of soul, as a principle of internal motion, was influential across ancient and medieval natural philosophy. In fact, the English language words animal and animation are derived from the Latin word for soul ( anima ).

Similarly, early thinkers like Xenophanes began to formulate explanations for natural phenomena. For instance, he explained rainbows, the sun, the moon, and St. Elmo’s fire (luminous, electrical discharges) as apparitions of the clouds. This form of explanation, describing some apparent phenomenon as the result of an underlying mechanism, is paradigmatic of scientific explanation even today. Parmenides, the founder of the Eleatic school of philosophy, used logic to conclude that whatever fundamentally exists must be unchanging because if it ever did change, then at least some aspect of it would cease to exist. But that would imply that what exists could not exist—which seems to defy logic. Parmenides is not saying that there is no change, but that the changes we observe are a kind of illusion. Indeed, this point of view was highly influential, not only for Plato and Aristotle, but also for the early atomists, like Democritus , who held that all perceived qualities are merely human conventions. Underlying all these appearances, Democritus reasoned, are only atomic, unchanging bits of matter flowing through a void. While this ancient Greek view of atoms is quite different from the modern model of atoms, the very idea that every observable phenomenon has a basis in underlying pieces of matter in various configurations clearly connects modern science to the earliest Greek philosophers.

Along these lines, the Pythagoreans provide a very interesting example of a community of philosophers engaged in understanding the natural world and how best to live in it. You may be familiar with Pythagoras from his Pythagorean theorem, a key principle in geometry establishing a relationship between the sides of a right-angled triangle. Specifically, the square formed by the hypotenuse (the side opposite the right angle) is equal to the sum of the two squares formed by the remaining two sides. In the figure below, the area of the square formed by c is equal to the sum of the areas of the squares formed by a and b. The figure represents how Pythagoras would have conceptualized the theorem.

The Pythagoreans were excellent mathematicians, but they were more interested in how mathematics explained the natural world. In particular, Pythagoras recognized relationships between line segments and shapes, such as the Pythagorean theorem describes, but also between numbers and sounds, by virtue of harmonics and the intervals between notes. Similar regularities can be found in astronomy. As a result, Pythagoras reasoned that all of nature is generated according to mathematical regularities. This view led the Pythagoreans to believe that there was a unified, rational structure to the universe, that the planets and stars exhibit harmonic properties and may even produce music, that musical tones and harmonies could have healing powers, that the soul is immortal and continuously reincarnated, and that animals possess souls that ought to be respected and valued. As a result, the Pythagorean community was defined by serious scholarship as well as strict rules about diet, clothing, and behavior.

Additionally, in the early Pythagorean communities, it was possible for women to participate and contribute to philosophical thought and discovery. Pythagoras himself was said to have been inspired to study philosophy by the Delphic priestess Themistoclea. His wife Theano is credited with contributing to important discoveries in the realms of numbers and optics. She is said to have written a treatise, On Piety , which further applies Pythagorean philosophy to various aspects of practical life (Waithe 1987). Myia, the daughter of this illustrious couple, was also an active and productive part of the community. At least one of her letters has survived in which she discusses the application of Pythagorean philosophy to motherhood. The Pythagorean school is an example of how early philosophical and scientific thinking combines with religious, cultural, and ethical beliefs and practices to embrace many different aspects of life.

How It All Hangs Together

Closer to the present day, in 1962, Wilfrid Sellars , a highly influential 20th-century American philosopher, wrote a chapter called “Philosophy and the Scientific Image of Man” in Frontiers of Science and Philosophy . He opens the essay with a dramatic and concise description of philosophy: “The aim of philosophy, abstractly formulated, is to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term.” If we spend some time trying to understand what Sellars means by this definition, we will be in a better position to understand the academic discipline of philosophy. First, Sellars emphasizes that philosophy’s goal is to understand a very wide range of topics—in fact, the widest possible range. That is to say, philosophers are committed to understanding everything insofar as it can be understood. This is important because it means that, on principle, philosophers cannot rule out any topic of study. However, for a philosopher not every topic of study deserves equal attention. Some things, like conspiracy theories or paranoid delusions, are not worth studying because they are not real. It may be worth understanding why some people are prone to paranoid delusions or conspiratorial thinking, but the content of these ideas is not worth investigating. Other things may be factually true, such as the daily change in number of the grains of sand on a particular stretch of beach, but they are not worth studying because knowing that information will not teach us about how things hang together. So a philosopher chooses to study things that are informative and interesting—things that provide a better understanding of the world and our place in it.

To make judgments about which areas are interesting or worthy of study, philosophers need to cultivate a special skill. Sellars describes this philosophical skill as a kind of know-how (a practical, engaged type of knowledge, similar to riding a bike or learning to swim). Philosophical know-how, Sellars says, has to do with knowing your way around the world of concepts and being able to understand and think about how concepts connect, link up, support, and rely upon one another—in short, how things hang together. Knowing one’s way around the world of concepts also involves knowing where to look to find interesting discoveries and which places to avoid, much like a good fisherman knows where to cast his line. Sellars acknowledges that other academics and scientists know their way around the concepts in their field of study much like philosophers do. The difference is that these other inquirers confine themselves to a specific field of study or a particular subject matter, while philosophers want to understand the whole. Sellars thinks that this philosophical skill is most clearly demonstrated when we try to understand the connection between the natural world as we experience it directly (the “manifest image”) and the natural world as science explains it (the “scientific image”). He suggests that we gain an understanding of the nature of philosophy by trying to reconcile these two pictures of the world that most people understand independently.

Read Like a Philosopher

“philosophy and the scientific image of man”.

This essay, “ Philosophy and the Scientific Image of Man ” by Wilfrid Sellars, has been republished several times and can be found online. Read through the essay with particular focus on the first section. Consider the following study questions:

• What is the difference between knowing how and knowing that? Are these concepts always distinct? What does it mean for philosophical knowledge to be a kind of know-how?
• What do you think Sellars means when he says that philosophers “have turned other special subject-matters to non-philosophers over the past 2500 years”?
• Sellars describes philosophy as “bringing a picture into focus,” but he is also careful to recognize challenges with this metaphor as it relates to the body of human knowledge. What are those challenges? Why is it difficult to imagine all of human knowledge as a picture or image?
• What is the scientific image of man in the world? What is the manifest image of man in the world? How are they different? And why are these two images the primary images that need to be brought into focus so that philosophy may have an eye on the whole?

Unlike other subjects that have clearly defined subject matter boundaries and relatively clear methods of exploration and analysis, philosophy intentionally lacks clear boundaries or methods. For instance, your biology textbook will tell you that biology is the “science of life.” The boundaries of biology are fairly clear: it is an experimental science that studies living things and the associated material necessary for life. Similarly, biology has relatively well-defined methods. Biologists, like other experimental scientists, broadly follow something called the “scientific method.” This is a bit of a misnomer, unfortunately, because there is no single method that all the experimental sciences follow. Nevertheless, biologists have a range of methods and practices, including observation, experimentation, and theory comparison and analysis, that are fairly well established and well known among practitioners. Philosophy doesn’t have such easy prescriptions—and for good reason. Philosophers are interested in gaining the broadest possible understanding of things, whether that be nature, what is possible, morals, aesthetics, political organizations, or any other field or concept.
