I call myself a Possibilian: I'm open to...ideas that we don't have any way of testing right now.

The first lesson about trusting your senses is: don't. Just because you believe something to be true, just because you know it's true, that doesn't mean it is true.

The brain runs its show incognito.

The continuous networks of neural circuitry accomplish their functions using multiple, independently discovered strategies. The brain lends itself well to the complexity of the world, but poorly to clear-cut cartography.

Consciousness is the smallest player in the operations of the brain.

Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.

When the brain activity is kindled in the right spot, people hear voices. If a physician prescribes an anti-epileptic medication, the seizures go away and the voices disappear. Our reality depends on what our biology is up to.
