Single Idea 12638

[filed under theme 18. Thought / D. Concepts / 3. Ontology of Concepts / c. Fregean concepts ]

Full Idea

How are we to understand the connection between the identity of a concept and its causal powers if concepts are (or have) senses? Answer: I haven't a clue.

Gist of Idea

If concepts have sense, we can't see the connection to their causal powers

A Reaction

This seems to be the key to Fodor's attack on Peacocke and other Fregeans - that while they pay lip-service to the project of naturalising thought, they are actually committing us to some sort of neo-platonism, by losing the causal links. See Idea 12636.
