Full Idea

Intensional logic aims to capture necessary relations between certain predicates, such as that 'green all over' and 'red all over' cannot be co-instantiated. Each predicate is allocated a set of points in logical space, and every object has one point.

Gist of Idea

Intensional logic maps logical space, showing which predicates are compatible or incompatible
