from "You are not your brain," by Alva Noe (interviewed by Gordy Slack), Salon, 25 March 2009 :: via 3quarksdaily

It’s one thing to say you wouldn’t be you if not for your brain, that your brain is critical to what you are. But I could say that about your upbringing and your culture, too. It’s another thing entirely to say that you are your brain.

I don’t reject the idea that the brain is necessary for consciousness; but I do reject the argument that it is sufficient. That’s just a fancy, contemporary version of the old philosophical idea that our true selves are interior, cut off from the outside world, only accidentally situated in the world. The view I’m attacking claims that neural activity is enough to explain consciousness, that you could have consciousness in a petri dish. It supposes that consciousness happens inside the brain the way digestion occurs inside the GI tract. But consciousness is not like digestion; it doesn’t happen inside of us. It is something we do, something we achieve. It’s more like dance than it is like digestion.

Even if we had a perfect way of observing exactly what a brain was doing, we would never be able to understand how it made us have the kinds of experiences we do. The experiences just aren’t happening inside our skulls. Trying to understand consciousness in neural terms alone is like trying to understand a car driving down the road only in terms of its engine. It’s bad philosophy masquerading as science….

Just as an engine is necessary in a car. But an engine doesn’t “give rise” to driving; driving isn’t something that happens inside the engine. The engine contributes to the car’s ability to drive. Consciousness is more like driving than our philosophical tradition leads us to expect. To be conscious is to have a world. The fact is, you and I don’t have what it takes to make a world on our own. We find the world, we don’t make it in our brains.

The brain is essential for our lives, physiology, health and experience. But the idea that it is the whole story, or even the key to understanding the story, is not a scientific conclusion. It’s a prejudice. Consciousness requires the joint operation of the brain, the body and the world.
