Global warming is a deadly threat precisely because it fails to trip the brain's alarm, leaving us soundly asleep in a burning bed.

The eye and brain are conspirators, and, like most conspiracies, theirs is negotiated behind closed doors, in the back room, outside of our awareness.

The fact that we often judge the pleasure of an experience by its ending can cause us to make some curious choices.

The brain and the eye may have a contractual relationship in which the brain has agreed to believe what the eye sees, but in return the eye has agreed to look for what the brain wants.

Everyone who has observed human behavior for more than thirty continuous seconds seems to have noticed that people are strongly, perhaps even primarily, perhaps even single-mindedly, motivated to feel happy.

Few of us can accurately gauge how we will feel tomorrow or next week. That's why when you go to the supermarket on an empty stomach, you'll buy too much, and if you shop after a big meal, you'll buy too little.

We humans can look deep into future and predict what will happen, but then turn around and do nothing about it.
