Consciousness Isn’t a Mystery. It’s Matter.

Every day, it seems, some verifiably intelligent person tells us that we don’t know what consciousness is. The nature of consciousness, they say, is an awesome mystery. It’s the ultimate hard problem. The current Wikipedia entry is typical: Consciousness “is the most mysterious aspect of our lives”; philosophers “have struggled to comprehend the nature of consciousness.”

I find this odd because we know exactly what consciousness is — where by “consciousness” I mean what most people mean in this debate: experience of any kind whatever. It’s the most familiar thing there is, whether it’s experience of emotion, pain, understanding what someone is saying, seeing, hearing, touching, tasting or feeling. It is in fact the only thing in the universe whose ultimate intrinsic nature we can claim to know. It is utterly unmysterious.

The nature of physical stuff, by contrast, is deeply mysterious, and physics grows stranger by the hour. (Richard Feynman’s remark about quantum theory — “I think I can safely say that nobody understands quantum mechanics” — seems as true as ever.) Or rather, more carefully: The nature of physical stuff is mysterious except insofar as consciousness is itself a form of physical stuff. This point, which is at first extremely startling, was well put by Bertrand Russell in the 1950s in his essay “Mind and Matter”: “We know nothing about the intrinsic quality of physical events,” he wrote, “except when these are mental events that we directly experience.” In having conscious experience, he claims, we learn something about the intrinsic nature of physical stuff, for conscious experience is itself a form of physical stuff.
