Naturalism (philosophy)

Naturalism is any of several philosophical stances, typically those descended from materialism and pragmatism, that does not distinguish between the supernatural and the natural. It does not claim that phenomena or hypotheses commonly labeled supernatural necessarily do not exist or are wrong, but insists that they are not inherently different from any other hypotheses or phenomena and can be studied by the same methods.

Naturalism and philosophy of mind

There is currently some dispute over whether naturalism rules out certain areas of philosophy altogether, such as semantics, ethics, aesthetics, or excludes the use of mentalistic vocabulary ("believes," "thinks,") in philosophy of mind. Quine avoided most of these topics, but some recent thinkers have argued that even though (according to them) mentalistic descriptions and value judgements cannot be systematically translated into physicalistic descriptions, they also do not need to presuppose the existence of anything other than physical phenomena.

Donald Davidson, for example, has argued that individual mental states can (must, in fact) be identical with individual brain states, even though a given kind of mental state (belief in Santa Claus) might not be systematically identified with a given kind of brain state (a particular pattern of neural firings): the former weakly "supervenes" upon the latter. The implication is that naturalism can leave non-physical vocabulary intact where the use of that vocabulary can be explained naturalistically; McDowell has dubbed this level of discourse "second nature."
