It's Georges Rey. I know because I sat through an entire class that he taught once. I think I also read his book, Contemporary philosophy of mind: a contentiously classical approach, during that time, but I don't recall learning anything from it.

Can someone who has actually read the paper (I don't feel like it) tell me whether it has the same upshot as the earlier version I seem to remember, viz. that people only pretend to believe in God? (It's possible I've got this mixed up with something else.)
