I said I didn’t want to say anything about free will, and I still don’t, but Massimo Pigliucci weighed in, and Jerry Coyne responded, and so did Sean Carroll, and of course I created a free will thread for everyone else to talk about it, so I guess there’s a fair bit of momentum behind it all.

I don’t understand why free will was getting all tangled up in indeterminacy vs. determinism, since that seems to be a completely independent issue. I’ll sum up my opinion by agreeing with Jerry Coyne:

Of course, whether the laws of physics are deterministic or probabilistic is, to me, irrelevant to whether there’s free will, which in my take means that we can override the laws of physics with some intangible “will” that allows us to make different decisions given identical configurations of the molecules of the universe. That kind of dualism is palpable nonsense, of course, which is why I think the commonsense notion of free will is wrong.

My mind is a product of the physical properties of my brain; it is not above them or beyond them or somehow independent of them. It doesn’t even make sense to talk about “me”, which is ultimately simply yet another emergent property of the substrate of the brain, modifying the how the brain acts. It is how the brain acts.

I think consciousness is a product of self-referential modeling of how decisions are made in the brain in the absence of any specific information about the mechanisms of decision-making — it’s an illusion generated by a high-level ‘theory of mind’ module that generates highly simplified, highly derived models of how brains work that also happens to be applied to our own brain.
