Abstract

John Searle claims that reasoning requires libertarian free will. He hopes this can be reconciled with a naturalistic neuroscience through a sophisticated theory of emergence, which includes indeterminism, and topdown causation. This is allegedly naturalistic because each mental state is causally reducible to a realizing neuronal state. I argue that Searle’s theory fails to overcome four main problems and cannot account for reasoning without implicit appeal to nonnaturalistic entities.
