Abstract

Peter Geach has charged Aristotle with the sin of corrupting logic by initiating a process which led to the view that a sentence consists logically of just two names. This charge can only result from a clearly mistaken view of Aristotle's theory of logical syntax. Aristotle, unlike Geach, was careful to distinguish subjects from subject-terms and predicates from predicate-terms. He took both subjects and predicates as syntactical complexes. Geach, following Frege, holds a very different theory of logical syntax which takes predicates, but not subjects, as syntactically complex.
