Abstract
Carruthers’s central project in Phenomenal Consciousness is to naturalize consciousness. Given the vast success of naturalism in science, he maintains that we should require powerful reasons to abandon it when constructing philosophical theories of consciousness. Unsurprisingly, he then argues that there are no such reasons. In particular, he claims that the well-known arguments of Thomas Nagel and Frank Jackson fail, as do inverted and absent qualia arguments. Carruthers’s main strategy for defusing these arguments involves first distinguishing a “thin” notion of property from a “thick” notion of property and then arguing that the various antinaturalistic arguments conflate these two different notions. Although he admits that the antinaturalist may not find these considerations wholly convincing, he construes the dialectical situation in such a way as to relieve him of any obligation to do more. As long as it can be shown that the antinaturalistic arguments are not obviously successful, which he takes himself to have done, Carruthers claims that the presumption in favor of naturalism remains. Thus, a theory of consciousness must be compatible with the following two naturalistic claims: first, all mental events occur in accordance with causal laws; and second, all mental events can be given a reductive explanation in physical terms.
