Common sense is merely unaided intuition, and unaided intuition is reasoning performed in the absense of instruments and the tested knowledge of science. Common sense tells us that massive satellites cannot hang suspended 36,000 kilometers above the one point on the earth's surface, but they do.

We are not afraid of predators, we're transfixed by them, prone to weave stories and fables and chatter endlessly about them, because fascination creates preparedness, and preparedness, survival. In a deeply tribal way, we love our monsters.

Human nature is deeper and broader than the artificial contrivance of any existing culture.

The laws of biology are written in the language of diversity.

An individual ant, even though it has a brain about a millionth of a size of a human being's, can learn a maze; the kind we use is a simple rat maze in a laboratory. They can learn it about one-half as fast as a rat.

The human race is not divided into two opposing camps of good and evil. It is made up of those who are capable of learning and those who are incapable of doing so.
