Book Description: In this highly anticipated new book, the bestselling author of The End of Faith and Letter to a Christian Nation call for an end to religionâ€™s monopoly on morality and human values. The End of Faith ignited a worldwide debate about the validity of religion. In the aftermath, Sam Harris discovered that most people, from secular scientists to religious fundamentalists, agree on one point: Science has nothing to say on the subject of human values. Indeed, scienceâ€™s failure to address questions of meaning and morality has become the primary justification for religious faith. Now, in this explosive new book, Harris tears down the wall between scientific facts and human values. Bringing a fresh, secular perspective to age-old questions of right and wrong, and good and evil, Harris shows that we know enough about the human brain and its relationship to events in the world to say that there are right and wrong answers to the most pressing questions of human life. Because such answers exist, cultural relativism is simply falseâ€”and comes at increasing costs to humanity. And just as there is no such thing as Christian physics or Muslim algebra, there can be no Christian or Muslim morality. Using his expertise in philosophy and neuroscience, along with his experience on the front lines of our â€śculture wars,â€ť Harris delivers a game-changing argument about the future of science and about the real basis of human cooperation.
