EXTREMES, in Logic, denote the two extreme terms of the conclusion of a syllogism; viz. the predicate and subject. They are called extremes, from their relation to another term, which is a medium or mean between them. The predicate, as being likewise had in the first proposition, is called the majus extremum, greater extreme; and the subject, as being put in the second or minor proposition, is called the minus extremum, lesser extreme. Thus, in the syllogism, man is an animal; Peter is a man, therefore Peter is an animal; the word animal is the greater extreme, Peter the less extreme, and man the medium. See SYLLOGISM.
