For decades, Richard Dawkins was known for his work as an evolutionary biologist, but with this impassioned 2006 rebuttal of religion, he became the leading figure of the New Atheism. Taking aim at creationism and intelligent design, Dawkins also calls out the dangers of fundamentalism—from the Crusades to 9/11—noting how religious dogma has been used to limit the rights of women, children, and homosexuals. Building a case for atheism, Dawkins argues that non-believers can live happy and moral lives, appreciating the wonders of the universe without recourse to unfounded supernatural beliefs.
