Abstract

This article considers a Quine-Dennett style of argument from the indeterminacy of intentional content against the reducibility of mental states to neurological states. The most compelling version of such an argument, I suggest, is one that exploits a semantic anti-realist notion of truth; this holds out the promise of a relatively sophisticated story about the respects in which mental state attributions may be true or false of physical systems, without those states themselves being physical states.
