Some believers are fundamentalists about everything, but every believer is a fundamentalist about something.

If you can't think of an observation that could disprove a theory, that theory simply isn't scientific.

A well-understood and testable hypothesis like sexual selection surely trumps an untestable appeal to the inscrutable caprices of a creator.

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.

In the end theologians are jealous of science, for they are aware that it has greater authority than do their own ways of finding "truth": dogma, authority, and revelation. Science does find truth, faith does not.

We don't have faith in reason; we use reason because, unlike revelation, it produces results and understanding. Even discussing why we should use reason employs reason!
