In this thread, I have been defending the position that free will should be defined in a way that makes it compatible with determinism. This is the position taken by compatibilists such as Daniel Dennett. However, there are other defenses of compatibilism out there besides Dennett, and I think that Christian List is a rising young philosopher who has taken a slightly different approach, especially in his well-received book Why Free Will is Real. I have not read this book yet, but you can get an idea of how List approaches the debate in this relatively short essay by him:
Basically, he attacks the popular reductionist approach that people take when they try to claim that free will is an illusion or not real. Another word for this kind of attack on so-called "folk psychology" is Eliminative Materialism, although I don't know whether List gets into such terminology in his writings. List points out that the field of psychology has not been replaced by neuropsychological reductionism because there is a need to describe mental processes at a higher level just in order to be able to study them scientifically. Reductionism may help to explain some aspect of the high level mental activity, but it isn't helpful in answering every question that one has about that activity. To put it another way, being a physicist may explain a lot about the nuts and bolts of how objects interact with each other, but it isn't necessary to be a physicist to be a good auto mechanic. The field of physics isn't equipped to describe what went wrong with your car in a useful way, and you wouldn't go to a scientist to get it repaired. You would go to a mechanic. That's not to say that physicists have nothing useful to say about what makes automobiles run. Similarly, determinism is useful in describing the nature of how the material world behaves, but it is too low level to be useful in explaining how humans behave when they make choices.
Anyway, I recommend that people take a look at the essay cited above rather than just rely on my description of List's arguments.
