B Side

"And once physicists got down to the serious business of building bombs, we were apparently returned to a universe of objects—and to a style of discourse, across all branches of science and philosophy, that made the mind seem ripe for reduction to the 'physical' world."

Absolutely nothing about a brain, when surveyed as a physical system, suggests that it is a locus of experience.

Consciousness—the sheer fact that this universe is illuminated by sentience—is precisely what unconsciousness is not. And I believe that no description of unconscious complexity will fully account for it. It seems to me that just as “something” and “nothing,” however juxtaposed, can do no explanatory work, an analysis of purely physical processes will never yield a picture of consciousness. However, this is not to say that some other thesis about consciousness must be true. Consciousness may very well be the lawful product of unconscious information processing. But I don’t know what that sentence means—and I don’t think anyone else does either.
