We have become, by the power of a glorious evolutionary accident called intelligence, the stewards of life's continuity on earth. We did not ask for this role, but we cannot abjure it. We may not be suited to it, but here we are.

Everything comes to us in fifteen-second sound bites and photo opportunities. All possibility for ambiguity - the most precious trait of any adequate analysis - is erased.

Creationist critics often charge that evolution cannot be tested, and therefore cannot be viewed as a properly scientific subject at all. This claim is rhetorical nonsense.

Goethe died in 1832. As you know, Goethe was very active in science. In fact, he did some very good scientific work in plant morphology and mineralogy. But he was quite bitter at the way in which many scientists refused to grant him a hearing because he was a poet and therefore, they felt, he couldn't be serious.

What's important is that all human knowledge be made available to all intelligent people who want to learn it.

What you see is that the most outstanding feature of life's history is a constant domination by bacteria.
