[catalogued under 5. Theory of Logic / I. Semantics of Logic / 6. Intensionalism]

Full Idea

Intension cannot be identified with meaning. ..'Cube' and 'regular polyhedron with six square faces' are logically equivalent predicates. The intension is the same (the function giving the cubes in any possible world) but there is a difference of meaning.

Gist of Idea

Intension is not meaning, as 'cube' and 'square-faced polyhedron' are intensionally the same
