Abstract

Quite a number of contemporary students of logic tend to consider Aristotle's logic mainly from a formal point of view. Richard Patterson, on the other hand, attempts to show that Aristotle's system of logic as well as his modal logic must be studied in the light of his fundamental theory of syntax and his metaphysics. Even if all of Aristotle's modal logic has not been accepted in the West, the ideas underpinning it are those of his syllogistic logic. Patterson observes that, in his modal logic, Aristotle uses modal copulae rather than modal predicates.
