Sam Harris on using reason to build our morality

Many philosophers draw a hard line between the worlds of facts and values, but not Sam Harris. In this thought-provoking conversation with Chris, he makes the case that reason can indeed answer moral questions, and then explores the many controversies that emerge from that claim. Moral superiority? Cultural superiority? How about moral progress? Chris and Sam dig in to discuss the right ways to think about defining right from wrong, and reason’s role in it all.
