In my opinion computationalism is the only non-mysterious explanation of how the mind/brain works in principle. By "computationalism" I mean either any process that can be expressed by reducing formulas in the untyped lambda calculus, or, alternatively, all processes that can be expressed in some parallel approach to computation like the pi calculus. (I've never seen a conclusive argument why the "software" running on the mind/brain must be parallel, though. But there could be such an argument.) What alternatives are there? Other versions of functionalism seem to boil down to computationalism in the end - although the final verdict on this matter is open. Penrose's quantum approach is falsifiable, which is great, but there is not much evidence for it. Dualism is not compatible with modern physics, suffers from a variety of homunculus problems, and even if it was true, computationalism of the mind would still be the best explanation. (Computationalism does not imply physicalism, although most computationalists are physicalists.) Hypercomputation presumes ordinary computation, most hypercomputers are physically impossible, and there is no evidence that the mind/brain is a hypercomputer anyway. In any case the article does not define computationalism, so it's pointless.
