Identity theory of predication

Theory that subject/predicate statements are really identity statements, so that ‘X is red’ means ‘X is identical with some red thing’.

This is in effect the same as the theory Geach traces back to Aristotle (384-322 BC), but which is criticized even earlier by Plato (c.427-c.347 BC) in the Sophist, and treats predation in terms of a two-term theory, two-name theory, and two-class theory.
