I'm a dualist but for the sake of argument, one approach is to claim that however the brain functions, it should be explainable by physics, and if physics is computable, then it should in principle be simulable by a Turing Machine.

The question of whether physics is computable is a fascinating one I'd really like to see solved before I die.

[nirai]

Physics is most probably computable, since people created it; the real question is whether the world is (Turing) computable, and from my point of view it is clearly not. I find it remarkable that most people believe it is or that it might be.
