Authority. The opinions of those with significant experience, highly trained or possessing an advanced degree are often considered a form of proof. Their knowledge and familiarity within a given field or area of knowledge command respect and allow their statements to be criteria of truth.

What does validity mean in logic?

validity, In logic, the property of an argument consisting in the fact that the truth of the premises logically guarantees the truth of the conclusion. Whenever the premises are true, the conclusion must be true, because of the form of the argument.

What is the technical difference between a true argument and a valid argument?

--- An argument is valid if the truth of the conclusion follows from the truth of the premises. That is, an argument is valid if, when all the premises are true, the conclusion is necessarily true. The argument given above is valid, because if the two premises are both true, then the conclusion must be true.

How is the truth of a proposition related to the validity of an argument?

Its validity refers to the relation between its propositions—between the set of propositions that serve as the premises and the one proposition that serves as the conclusion of that argument. If the conclusion follows with logical necessity from the premises, we say that the argument is valid.

What is the relationship between soundness and validity?

A good argument is not only valid, but also sound. Soundness is defined in terms of validity, so since we have already defined validity, we can now rely on it to define soundness. A sound argument is a valid argument that has all true premises. That means that the conclusion of a sound argument will always be true.

What is the difference between valid and invalid argument?

Valid: an argument is valid if and only if it is necessary that if all of the premises are true, then the conclusion is true; if all the premises are true, then the conclusion must be true; it is impossible that all the premises are true and the conclusion is false. Invalid: an argument that is not valid.

How do you determine the validity of an argument?

Work out the truth-values of premises and conclusion on each row. Check to see if there are any rows on which all of the premises are true and the conclusion false (counterexamples). If there are any counterexample rows, the argument is formally invalid. If there are none, it's formally valid.
