> You brain has hallucinated not just the outside world, but your internal world as well.

Very interesting. I agree with these statements--yet I also think they are perfectly consistent with people making choices. In your ultra-physicalist language, human brains hallucinating "the outside world" and "the internal world" are just part of the causal processes that happen inside those brains. And those causal processes still have effects outside those brains even so.

Those causal processes still have effects outside those brains does not remove the idea that your brain only exists because of external causal events, and your brain is only reacting to those external causal events. At no point is there a spontaneous reaction that is unpredictable according to the known laws of physics, therefore, you don't have free will.

> your brain is only reacting to those external causal events

No, it isn't "only reacting". It is processing the incoming causal events, in a very complex way that "only reacting" doesn't even begin to scratch the surface of describing.

> At no point is there a spontaneous reaction that is unpredictable according to the known laws of physics, therefore, you don't have free will.

This definition of "free will" is pointless. Obviously nobody can violate the laws of physics, so if "free will" means violating the laws of physics, of course it's impossible. But nobody cares about that kind of "free will". The kind of free will people care about is having their right to make choices respected. Your metaphysical claims do not address that at all; and from what I can gather of your image of what society should be, it would be a horror worse than the worst tyrannies in history.

[Layke1123]

You can't claim it that "only reacting" doesn't help explain the process because at the end of they day, you, nor I, can exactly explain how consciousness works. The only evidence we have to likely explain it is that it likely is a cause and effect system like EVERYTHING we can observe externally so far.

And again, just because you claim my world view would be tyrannical DOES NOT make it true. My definition of free will is the common understanding of free will that you are trying to redefine to fit your world view.

[pdonis]

> it likely is a cause and effect system

Of course consciousness is a cause and effect system like everything else. I have never claimed otherwise, and the viewpoint I am defending certainly does not require otherwise.

> My definition of free will is the common understanding of free will

The common understanding of free will is that people can make choices and that those choices affect what happens to them. That can be true even in the deterministic universe you say you believe in.

[Layke1123]

It is not free will in the sense that you can spontaneously decide it for yourself. I can choose to eat vanilla yogurt or plain yogurt. That is the narrative my brain hallucinates. The reality behind the illusion is that the choice was made before I even am aware of the "story I tell myself" that I chose one or the other.

> It is not free will in the sense that you can spontaneously decide it for yourself.

If "spontaneously" means "outside of the laws of physics", then of course I agree. I just don't think that kind of "free will" is the only possible kind of free will, nor do I think that impossible kind of free will is the kind of free will that matters.

> I can choose to eat vanilla yogurt or plain yogurt. That is the narrative my brain hallucinates. The reality behind the illusion is that the choice was made before I even am aware of the "story I tell myself" that I chose one or the other.

Of course this is true in the sense that, as far as we can tell, the brain process of you being aware of your choice happens either at the same time as, or after, the brain process that makes your choice. But so what? All those processes are still happening in your brain.

Compare what you just described with this scenario: you want vanilla yogurt, but I force you to have plain yogurt instead because I believe it's healthier for you. Here there are still processes happening in your brain, which, if I weren't there, might well have led to you eating vanilla yogurt--but because I am there and I force you to eat plain yogurt, your brain processes do not determine what kind of yogurt you eat--instead, my brain processes do.

Do you see any meaningful difference between those scenarios? I sure do. (And note that I think that difference is meaningful even if it is true that the plain yogurt would be healthier.) If you don't, then we have a fundamental disagreement that I don't think any discussion can resolve.
