Which is the error of the materialist. > or "It's all simulated inside arithmetic" have perfect explanatory power. Not at all. This is refuted by Mechanism (Descartes, Darwin, Turing, …). The physical universe is NOT simulated by any computer, given that it arises from a non computable (non simulable) statistics on all simulations. It might be, or not, relatively well approximable by some computations, but that’s all we can hope.
