The three-pound organ in your skull - with its pink consistency of Jell-o - is an alien kind of computational material. It is composed of miniaturized, self-configuring parts, and it vastly outstrips anything we've dreamt of building.

Awareness of your surroundings occurs only when sensory inputs violate expectations. When the world is successfully predicted away, awareness is not needed because the brain is doing its job well.

Every atom in your body is the same quark in different places at the same moment in time.

When one part of the brain makes a choice, other parts can quickly invent a story to explain why. If you show the command "Walk" to the right hemisphere (the one without language), the patient will get up and start walking. If you stop him and ask why he's leaving, his left hemisphere, cooking up an answer, will say something like "I was going to get a drink of water."

If you cannot always elicit a straight answer from the unconscious brain, how can you access its knowledge? Sometimes the trick is merely to probe what your gut is telling you. So the next time a friend laments that she cannot decide between two options, tell her the easiest way to solve her problem: flip a coin. She should specify which option belongs to heads and which to tails, and then let the coin fly. The important part is to assess her gut feeling after the coin lands. If she feels a subtle sense of relief at being "told" what to do by the coin, that's the right choice for her.

All life will die, all mind will cease, and it will all be as if it had never happened. That, to be honest, is the goal to which evolution is traveling, that is the "benevolent" end of the furious living and furious dying.

Visual cortex is fundamentally a machine whose job is to generate a model of the world.
