A kind of → deductive reasoning whereby from two initial → propositions (two → premises) a third related proposition (→ conclusion) is derived. The typical form of a → categorical syllogism is "A is B;" "C is A;" "Therefore, C is B." For example, "All humans are mortal." "John is human." "Therefore, John is mortal." "Mortal" (B) is called the → major term; it occurs in the first premise and is the → predicate of the conclusion. "John" (C), the subject of the conclusion, is called the → minor term. "Human," which is common to both premises and is excluded from the conclusion, is called the → middle term. See also → Aristotelian forms. Syllogism is purely formal. It does not enrich knowledge, but gives a new presentation to what is already known. It is also possible to have a logically valid syllogism based on → absurd premises. For example, "All cats are mammals." "All cats are animals." "Therefore, all animals are mammals." Syllogism, representing the earliest branch of → formal logic, was developed in its original form by Aristotle in his Organon (Prior Analytics) about 350 BC.
