physical-functional concepts." Papineau (2002, pp. 97-102 & pp. 179-180) argues that phenomenal concepts and physical/functional concepts lack inferential connections to one another. Carruthers & Veillet (2007, p. 213) insists that phenomenal concepts "are conceptually isolated from any other concepts that we possess, lacking any a-priori connections with non-phenomenal concepts of any type (and in particular, lacking such connections with any physical, functional, or intentional concepts)." Block (1990 offers several arguments for the conclusion that the qualitative aspects of experience, or P-consciousness, lack conceptual connections to functional structure.
