Militant atheist Sam Harris has a new book out: "The Moral Landscape: How Science Can Determine Human Values". An excerpt was published in today's Post. I haven't read the book yet but from the excerpt, it appears that Harris has been engaging in some fanciful speculation that "science", neuro-science in particular, will someday be capable of producing objective answers to ethical and moral questions. Apparently the "correctness" of these answers would be produced based on their utility in improving (or otherwise) our "well-being". This sounds at least as dubious as the notion socialists fervently cling to, despite all the evidence to the contrary, that it is possible for governments to comprehend all the variables necessary to control ecomomic systems to the net benefit of human "well-being".
An atheist and Harris fan provides a particularly thoughtful review. There's a good debate in the comments to his review too.
