By Tom Flynn
Atheists may be hot on today's best-seller lists, but nonbelievers have always played an important role in shaping moral and political thought. Explore this gallery for profiles of selected atheists, agnostics, and freethinkers featured in the documentary A Brief History of Disbelief, airing in early May on PBS (watch a video clip).
Tom Flynn is media director of the Center for Inquiry, editor of the secular humanist magazine Free Inquiry, and editor of the forthcoming New Encyclopedia of Unbelief.
