- the TRADITIONAL term used in DEDUCTIVE LOGIC for an argument with a specific structure that includes two PROPOSITIONS and a conclusion. On the basis of its formal structure a syllogism may be judged logically VALID. If the propositions are also true in terms of their correspondence to REALITY, then the syllogism is deemed sound. An example of a valid syllogism would beAll pigs have wings; All winged things fly; therefore pigs fly. This would be valid but is clearly untrue and therefore unsound. A sound syllogism would be one such as the classic exampleAll men are mortal; Socrates is a man; therefore Socrates is mortal.
