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!

All scientific progress requires a climate of strong skepticism.

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.

We are the one creature to whom natural selection has bequeathed a brain complex enough to comprehend the laws that govern the universe. And we should be proud that we are the only species that has figured how we came to be.

Faith is a padlock of the mind, and few keys can open it.

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