Neo-atheist Sam Harris delivers a lecture on morality in which he argues, sometimes sensibly, against moral relativism. Unfortunately, he seeks to ground his argument in the belief that somehow science can tell us what is objectively right and what is objectively wrong. He sets human flourishing as his summum bonum and then argues that whatever promotes that flourishing is right and whatever impedes it is wrong.
But why should we think that human flourishing is the summum bonum? His answer seems to be because we just feel that it is, and anyone who doesn't feel this way is wrong. Not only is this unpersuasive, it also leaves unanswered the question of why, if flourishing is indeed the greatest good we can pursue, I shouldn't pursue it just for myself or why our nation shouldn't pursue it at the expense of other nations. Why should anyone care about the flourishing of others? Why is it wrong to subordinate other people's flourishing to my own? And if death is the end what does it matter how we live anyway? Why not maximize whatever pleasures are to be found in life and let other people take care of themselves?
Harris, unfortunately, doesn't address those questions, but they really are at the heart of the metaethical debate between theists and atheists. Atheism has no answer to questions like why I should care for the poor, or why we should conserve the earth's resources, or why I should contribute to Haitian earthquake relief. The fact is that there's simply no reason why one should sacrifice anything for others unless it's in his own self-interest somehow to do so.
Here's Harris' lecture:
It's a peculiarity among science-oriented atheists like Harris that they so often argue that we should all behave in certain ways because, well, it feels to them like we should. The oddest thing about the lecture, though, is that he was given a standing ovation at its conclusion. Having listened to nothing significant for twenty five minutes or so the audience jumped to their feet to express their approval. Pretty funny.
