Abstract

Phenomenal concepts are the concepts that we deploy when – but arguably not only when – we introspectively examine, focus on, or take notice of the phenomenal character of our experiences. They refer to phenomenal properties (or qualities) and they do so in a subjective (first-personal) and direct (non-relational) manner. It is through the use of such concepts that the phenomenal character of our experiences is made salient to us. Discourse about the nature of phenomenal concepts plays an important role in the philosophy of mind. For one, phenomenal concepts have been used to explain the epistemological relation that holds between a subject and her conscious mental states. Most prominently, however, discussions of phenomenal concepts figure in the on-going and multifaceted debate concerning the metaphysical status of consciousness. Even though some theorists have utilized phenomenal concepts in arguments purporting to show that consciousness is ontologically distinct from physical entities and processes, most accounts of phenomenal concepts are advanced having the opposite objective in mind: a proper articulation of the nature of phenomenal concepts, it is held, can defend the view that consciousness is physical against epistemic arguments to the contrary. The present entry focuses on the nature of phenomenal concepts as this is articulated and developed in attempts to defend the contention that conscious states are identical to (realized by, metaphysically necessitated by, or supervenient upon) physical states.
