Sam Harris has 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, science's failure to address questions of meaning and morality has become the primary justification for religious faith. The underlying claim is that while science is the best authority on the workings of the physical universe, religion is the best authority on meaning, values, morality, and leading a good life. Sam Harris shows us that this is not only untrue; it cannot possibly be true. 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 how it reacts 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, moral relativism is simply false - and comes at increasing cost to humanity. Using his expertise in philosophy and neuroscience, along with his experience on the front lines of the cultural war between science and religion, in "The Moral Landscape" Harris delivers an explosive argument about the future of science, and about the real basis of human relationships.
