Cats - a standing rebuke to behavioural scientists . . . least human of all creatures.

I don't want to be reincarnated, that's for sure. When you've had rewarding experiences in your life - a loving family, friends - you don't need additional reassurances that you're going to do something with a new cast of characters. I'd just as soon pass.

If we are to be destroyed we will do it ourselves by warfare with thermonuclear weaponry.

Left to ourselves, mechanistic and autonomic, we hanker for friends.

For total greed, rapacity, heartlessness, and irresponsibility there is nothing to match a nation.

I do not agree with this century's fashion of running down the human species as a failed try, a doomed sport. At our worst, we may be going through the early stages of adolescence, and everyone remembers what that is like.

There's really no such thing as the agony of dying. I'm quite sure that pain is shut off at the moment of death. You see, something happens when the body knows it's about to go. Peptide hormones are released by cells in the hypothalamus and pituitary gland. Endorphins. They attach themselves to the cells responsible for feeling pain.
