The Distinction: Two Kinds of Consciousness
Block's seminal contribution: differentiating between two distinct forms of consciousness, crucial for understanding mental experience.
P-consciousness (Phenomenal)
A-consciousness (Access)

This distinction highlights that while we might access information about our experiences, the subjective feeling itself is a separate,

The Blockhead Experiment
A Powerful Critique of Functionalism
Block's "Blockhead" thought experiment challenges the functionalist view that
mental states are simply functional states.

Against Reductionism:
Consciousness Beyond
Computation
"Consciousness is not reducible to mere computations or neural processes. It
has a subjective, experiential dimension that cannot be fully captured by these
alone."
Ned Block fundamentally challenges the idea that consciousness can be entirely
explained away by reducing it to its physical components or computational
functions.
He contends that while brain processes are essential, they do not fully account
for the qualitative, subjective nature of phenomenal consciousness.
Block emphasizes that reducing consciousness to neural activity alone
overlooks the crucial 'what it's like' aspect of experience.
