Who Says Science has Nothing to Say About Morality?

I think Sam Harris is of immense importance as a philosopher because he has challenged David Hume’s classic assertion that you can’t get an ought from an is. That is to say Mr. Harris shows that there are descriptive facts about the way the world is that can tell us how the world ought to be. His book The Moral Landscape is an invaluable addition to the annals of moral philosophy and therefore political philosophy.
