Richard Dawkins, a leading evolutionary biologist and author of many now-classic works of science and philosophy, has always stated unequivocally that belief in God is an irrationality that has caused many social ills. In this book, he offers a fierce critique of the idea of God in all its forms, from the sex-obsessed, callous tyrant of the Old Testament to the more mild, yet equally irrational, Celestial Watchmaker favored by some Enlightenment thinkers. He dismantles the main arguments in favor of religion and demonstrates that the existence of a higher being is an absolutely improbable scenario. He describes how religion fuels war, fosters intolerance, and abuses the minds and souls of children. The God Delusion is a fascinating polemic with dazzling arguments, a must-read for anyone interested in this emotionally charged and very important issue.
