Abstract

The current orthodoxy in the philosophy of mind can be thought of as a kind of third-person imperialism, viz. the view that consciousness, like other natural phenomena, will yield to scientific explanation at some level of analysis. Among its dissenters are a group of antireductionists and antimaterialists who advocate a kind of first-person isolationism, viz. the view that consciousness, unlike other natural phenomena, will fail to yield to scientific explanation at any level of analysis. In its various forms, the latter view is based on arguments that identify first-person phenomena, such as subjectivity and qualia, that no third-person approach to consciousness can explain. ;I argue that neither subjectivity nor qualia constitute insuperable obstacles for scientific explanations of consciousness. By identifying a set of persistent ambiguities within the subjectivity-based arguments of antiphysicalists, I provide a general framework for systematically locating fallacies within them. I then examine the common antiphysicalist assumption that the meanings of phenomenal concepts are fully determined by the conscious mental states to which they refer. By showing how it results in a commitment to the existence of essentially private language, I contend that this assumption is indefensible, and that antiphysicalist arguments that rely on it are therefore unsound. ;I then argue that qualia are intrinsic, basic, and subjective properties of conscious mental states, and that, contrary to antireductionists' suggestions, this higher-order classification is compatible with qualia reduction. I show this compatibility by examining the putative higher-order properties of qualia and comparing them to the higher-order properties characteristic of connectionist models of cognitive processes. I contend that the higher-order properties characteristic of connectionist networks approximate the putative higher-order properties of qualia sufficiently well to conclude that qualia reductionism can accommodate claims that qualia are intrinsic, basic, and subjective properties, and explain the motivating intuitions for those claims generated by inverted, absent, and alien qualia thought experiments. In this way I argue that the putative higher-order classifications of qualia not only fail to defeat qualia reduction but, ironically, turn out to support it
