 So how about metaphysical determinism for the human well? Cause and effect, everything in the mind has a physical correlate, you've told us. You're a Darwinian, the natural world is ruled by something like cause and effect, and the laws of nature haven't changed. So our minds are fully determined? Well, you didn't say yes. Yes, well, they may not be for any practical purpose determined in the sense that there may be processes that are chaotic, that are non-linear, where some ions zig instead of zag because of Brownian movement or maybe even quantum phenomena. And as a result, the whole system might behave in one way or another. That is physically determined, but for all practical purposes random, it may be so complex that it might be like the weather taken to several higher degrees that in theory perhaps Laplace's demon would be able to tell us what each of us will do next. But some things that are true in theory are so mind-bogglingly complicated that they may as well not be true in theory. So yeah, I don't think there's any miracle that goes on in the brain when we make a decision. In that sense, we're determined, on the other hand, there is so much unpredictability or non-linearity that for all intents and purposes we're not determined.
