Perhaps I should state it in a slightly different way. There is no reason for me or anyone else to doubt the clear perception we have of our own free will. Prove to me scientifically that it does not exist, that it is some kind of illusion that all human beings experience.

Fair enough. I'm glad you agree it's an empirical question.

Having got that concession from you, I'll tell you I actually don't agree with Chu-Carroll's analysis. Of course everything is definition-dependent here, but in essence, I don't think free will is an illusion. Rather, I think the opposition of determinism to free will is just mistaken. Determinism does not imply no free will. This position is called compatibilism.

What Chu-Carroll is saying is that free will is not some weird force outside physics that thaumaturgically makes an electron zig instead of zag, causing the miracle of choice. I agree up to there. So if that's what you call free will, then it is an illusion. He then implies "there is no free will." Indeed, not under that definition.

But that's not what I call free will.

See Daniel Dennett's "Elbow Room;" also search this site for "Free Will." Eliezer has done some excellent writing on the subject.
