Deductive Form: The premises are intended to provide conclusive reasons or proof of the conclusion. Inductive Form: The premises are intended to provide compelling but not conclusive reasons for the conclusion. Definitions these definitions are just two different ways of saying the same thing. Validity in the technical sense just defined applies only to arguments, never to individual claims.
If some argument is valid, then every argument with the same structure is also valid. If an argument has one or more false premises or it is not valid, then the argument is not sound. A valid argument must have a true conclusion. So it is possible for a valid argument to have a false conclusion as long as at least one premise is false.
A sound argument must have a true conclusion. TRUE : If an argument is sound, then it is valid and has all true premises. Since it is valid, the argument is such that if all the premises are true, then the conclusion must be true.
A sound argument really does have all true premises so it does actually follow that its conclusion must be true. If a valid argument has a false conclusion, then at least one premise must be false. Our hypothesis is that the function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade. Reasoning so motivated can distort evaluations and attitudes and allow erroneous beliefs to persist. They may result from innocent errors in reasoning, or be used deliberately to mislead others.
Taking logical fallacies at face value can lead you to make poor decisions based on unsound arguments. And using them yourself — even by mistake — can damage your reputation.
