Theology is the post hoc rationalization of what you want to believe.

Can a geology teacher blithely tell his students that the earth is flat, or a European history professor that the Holocaust didn't happen? That's not academic freedom, but dereliction of duty.

Because of the hegemony of fundamentalist religion in the United States, this country has been among the most resistant to the fact of human evolution.

If the history of science teaches us anything, it is that what conquers our ignorance is research, not giving up and attributing our ignorance to the miraculous work of a creator.

The biogeographic evidence for evolution is now so powerful that I have never seen a creationist book, article, or lecture that has tried to refute it. Creationists simply pretend that the evidence doesn't exist.

The fact that both Jews and Christians ignore some of God's or Jesus's commands, but scrupulously obey others, is absolute proof that people pick and choose their morality not on the basis of its divine source, but because it comports with some innate morality that they derived from other sources.

All scientific progress requires a climate of strong skepticism.
