This important and timely book delivers a startling analysis of the clash of faith and reason in today's world. Harris offers a vivid historical tour of mankind's willingness to suspend reason in favor of religious beliefs, even when those beliefs are used to justify harmful behavior and sometimes heinous crimes. He asserts that in the shadow of weapons of mass destruction, we can no longer tolerate views that pit one true god against another. Most controversially, he argues that we cannot afford moderate lip service to religion—an accommodation that only blinds us to the real perils of fundamentalism.
