In a lecture at the Center for Naturalism, author Daniel C. Dennett uses the "meme" theory to suggest how some ideas survive selection, and argues for mandatory education in world religions. While few would doubt the importance of understanding religion from a social perspective, some "bristle at anyone who wants to investigate their practices and beliefs in a scientific manner." (from the jacket cover). The book upon which the lecture is based, Breaking the Spell, is also available in the library's catalog.
