Full Idea
I now think, following Lycan, that my Causal theory of mentality would be strengthened (perhaps eliminating some potential counter-examples) by the addition of a teleological element.
Clarification
'Teleology' involves purpose
Gist of Idea
A causal theory of mentality would be improved by a teleological element

A Reaction
For Lycan, see Idea 6533. Armstrong has begun to realise that merely specifying the causal role of a mental state is too thin as an explanation. Teleology widens the notion of function. I also want to know about the properties that make it possible.
