But it's all physics, and either the physics is computable or it isn't. If the brain is not computable then there are physical process in it which are not computable. It may be the case; there is no a priori reason to assume that physics is computable, and the notion of non-computable functions is a legitimate one in mathematics. However, there is nothing in human behaviour that gives any indication of the computability of the physics in the brain. There is nothing conceptually or empirically in "sense" or "entropy" or the other terms you use to indicate whether the physics underlying them is computable or not. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
