Like Dennett said in an interview in this same section:
There are tousands of religions. A theist claims that all of them are untrue except for one. An atheist is just willing to go that last, extra step and declare them all wrong.
It doesn't require faith to NOT believe in something. Or even to "feel" that you are correct to do so. It doesn't require faith to accept scientific findings. The process of scientific discovery is designed to combat the need for faith. Its claims are falsifiable, and it makes no pretentions that any findings are final. All theory is subject to betterment. And this is the facet of science that distinguishes it from religion. With religion, all knowledge is handed down from a divine source and is final. When evidence contradicts those unmovable truths, you have to employ faith to combat the natural urge to accept observation. Science gladly changes over time, always attempting to get closer to an objective truth, even if such a goal is impossible. It doesn't even require any faith to accept this system as superior, just an understanding.
Science only seems to require faith when you are on the outside, with no understanding of the process, and no comprehension of the results. It is like technology that appears to be magical when you don't understand the underlying mechanisms.
