Scientific Morality

Sam Harris, author of The End of Faith and Letter to a Christian Nation, presented a TED talk called "Science can answer moral questions" earlier this month. While Harris' disdain for religion is evident and may consequently offend some people, I think his examination of the common themes in human values reaches an important conclusion:

"Values are a certain kind of fact. They are facts about the well-being of conscious creatures. Why is it that we don't have ethical obligations toward rocks? Why don't we feel compassion for rocks? It's because we don't think rocks can suffer. And if we're more concerned about our fellow primates than we are about insects, as indeed we are, it's because we think they're exposed to a greater range of potential happiness and suffering. Now, the crucial thing to notice here is that this is a factual claim. This is something we could be right or wrong about. If we've misconstrued the relationship between biological complexity and the possibilities of experience, well then we could be wrong about the inner lives of insects."
