Phenomenal, access and reflexive consciousness: The missing “blocks” in Ned Block’s typology

Abstract

This paper adds five “blocks” (cells) to Ned Block’s 2-by-2 P- and A-Consciousness typology, by converting “phenomenal” and “access” into two orthogonal dimensions of Primary Conscious, and by introducing gradations along each dimension, with P0 (no phenomenal experience), P1 (attenuated phenomenal experience), and P2 (full phenomenal experience); and A0 (no access of mental content to either involuntary or voluntary cognitive/behavioral responses), A1 (access of mental content to involuntary responses), and A2 (access of mental content also to voluntary responses). This leads to a 3x3, 9-block grid, with Phenomenality on the X-axis and Access on the Y-axis. Each combination of P and A is examined for known conscious states. It is concluded that there are no known phenomenal states without at least A1 or A2 access. Neither are there states with A2 access without P2 phenomenality. At the end of the paper, Block’s concept of Reflexive Consciousness is introduced tantalizingly as a third (Z) dimension for consciousness in humans.
