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?

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.

The fate of the paranormal is to become the normal as our horizons of understanding expand.

Scientific prayer makes God a celestial lab rat, leading to bad science and worse religion.

In science, if an idea is not falsifiable, it is not that it is wrong, it is that we cannot determine if it is wrong, and thus it is not even wrong.

Science is a set of methods designed to describe and interpret observed or inferred phenomenon, past or present, and aimed at building a testable body of knowledge open to rejection or confirmation.

Skepticism is not a position; it's a process.
