[from 'LOT 2' by Jerry A. Fodor, in 19. Language / B. Reference / 1. Reference theories ]

Full Idea

The representation of 'morning star' must be different from 'evening star' because their tokens differ in their causal powers.

Gist of Idea

Co-referring terms differ if they have different causal powers

A Reaction

This is Fodor trying to avoid the standard Fregean move of proposing that there are 'senses' as well as references. See Idea 12629. If these two terms have the same extension, they are the same concept? They 'seem' to have two referents.
