 The rules governing the distribution of terms in a sentence are given as part of his account of common personal supposition. A term is distributed in a sentence if it is taken to refer to everything it signifies, such as if the term is in the scope of a universal quantifier. To indicate when a term is distributed he gives five rules, according to which universals distribute subjects, negatives distribute predicates, and no other terms are distributed. If we stay within the square of opposition (Buridan’s theory of distribution, and hence his syllogistic, has wide application, extending far beyond the traditional A, E, I, and O sentences), this implies that universal affirmative sentences have their subject terms distributed, universal negatives have both terms distributed, particular affirmatives have neither term distributed, and particular negatives have only their predicate terms distributed. (For an influential criticism of this theory of distribution see Geach 1962, and King 1985 for a reply.)
