Human beings are works in progress that mistakenly think they're finished.

I have everything that I could possibly want in life, from a gorgeous granddaughter and a wonderful wife, brilliant students, the best job anyone could hope for, and about half of my hair. Not the half I would have kept, but no one consulted me.

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

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 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.

Impact is rewarding. Mattering makes us happy.

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