We think of our eyes as video cameras and our brains as blank tapes to be filled with sensory inputs.

Humans are, by nature, pattern-seeking, storytelling animals, and we are quite adept at telling stories about patterns whether they exist or not.

People have a hard time accepting free-market economics for the same reason they have a hard time accepting evolution: it is counterintuitive. Life looks intelligently designed, so our natural inclination is to infer that there must be an intelligent designer--a God. Similarly, the economy looks designed, so our natural inclination is to infer that we need a designer--a government. In fact, emergence and complexity theory explains how the principles of self-organization and emergence cause complex systems to arise from simple systems without a top-down designer.

Science is not the affirmation of a set of beliefs but a process of inquiry aimed at building a testable body of knowledge constantly open to rejection or confirmation. In science, knowledge is fluid and certainty fleeting. That is at the heart of its limitations. It is also its greatest strength.

We know evolution happened not because of transitional fossils such as A. natans but because of the convergence of evidence from such diverse fields as geology, paleontology, biogeography, comparative anatomy and physiology, molecular biology, genetics, and many more.

The question itself [of UFOs] I think is legitimate. It's interesting, it's fascinating. It's mythic in scale and one of the grand questions. It's like the God question or, you know, the meaning-of-life question. It's one of those, on that scale. So you'd have to be made of wood not to be interested and, you know, have they come here? Are they up there?

I’m a skeptic not because I do not want to believe, but because I want to know.
