Just as modern logicians have built up an elaborate body of thought by introducing one complication after another into the elementary propositional calculus, so logicians of the older type introduced one complication after another into the elementary theory of categorical syllogism. The first section of this chapter describes negative terms in Boethius and Augustus de Morgan. The second section defines the rules of equipollence. The third section considers syllogistic with conjunctive and alternative terms. The last section discusses the quantification of the predicate.

Keywords: negative terms; Boethius; Augustus de Morgan; equipollence; syllogistic; quantification
