"Consciousness matters. Arguably it matters more than anything. The purpose of this book is to build towards an explanation of just what the matter is."
Nicholas Humphrey begins this compelling exploration of the biggest of big questions with a challenge to the reader, and himself. What's involved in "seeing red"? What is it like for us to see someone else seeing something red? Seeing a red screen tells us a fact about something in the world. But it also creates a new fact - a sensation in each of our minds, the feeling of redness.
