With his unique brand of erudition and wit, Christopher Hitchens describes the ways in which religion is man-made. "God did not make us," he says. "We made God." He explains the ways in which religion is immoral: We damage our children by indoctrinating them. It is a cause of sexual repression, violence, and ignorance. It is a distortion of our origins and the cosmos. In the place of religion, Hitchens offers the promise of a new enlightenment through science and reason, a realm in which hope and wonder can be found through a strand of DNA or a gaze through the Hubble Telescope. As Hitchens sees it, you needn't get the blues once you discover the heavens are empty.
