"Forty-four percent of the American population is convinced that Jesus will return to judge the living and the dead sometime in the next 50 years," writes Sam Harris, who argues that politicians who subscribe to this belief could cause untold harm. After publishing The End of Faith, Harris received thousands of unhappy letters from believers. By way of reply, Harris offers a measured refutation of the beliefs that form the core of fundamentalist Christianity. Addressing current topics ranging from intelligent design and stem-cell research to the connections between religion and violence, Harris challenges the influence that faith has on public life in the United States.
