1)Validity deals with internal the proprieties of arguments. For a valid argument we supposing that if the premises are true - the conclusion must be true.

3. Valid vs Invalid Arguments. An argument has to satisfy the Logic Condition in order for it to qualify as a good argument. But there are two importantly different ways in which an argument can satisfy the Logic Condition. One way is if the argument is valid. Another way is if the argument is strong. "Validity" and "strength" are technical ...

There is a loose, hand-waving section on what this sense of validity means. In most texts, this is the HEART of critical thinking. How to tell valid from invalid arguments. At yet other times, there is a third use of the term validity. A viewpoint is more or less valid based upon the support it receives from arguments in favor of it.

Validity and Soundness. A deductive argument is said to be valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. Otherwise, a deductive argument is said to be invalid. A deductive argument is sound if and only if it is both valid, and all of its premises are ...

Critical Thinking. Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms ...

2. Logic and the Study of Arguments. If we want to study how we ought to reason (normative) we should start by looking at the primary way that we do reason (descriptive): through the use of arguments. In order to develop a theory of good reasoning, we will start with an account of what an argument is and then proceed to talk about what ...

In critical thinking and logic, 'argument' has a particular meaning. It refers to a set of statements, consisting of one conclusion and one or more premises.

We know that all humans die, so that's tight evidence. This argument would be a very good argument; it is valid (i.e the conclusion necessarily follows the premises) and it is sound (i.e. all the premises are true). Inductive Arguments: in an inductive argument the conclusion likely (at best) follows the premises. Let's have an example:

An argument is valid if and only if there is no logically possible situation where all the premises are true and the conclusion is false at the same time. The idea of validity provides a more precise explication of what it is for a conclusion to follow from the premises. Applying this definition, we can see that the first argument above is ...
