Am currently writing what is likely to be a very, very long review of The Moral Landscape (yes, it'll eventually be available online). I feel that I'm only scratching the surface, no matter how much detail I go into. Really, my practical viewpoint isn't very far from that of Sam Harris. Where we do disagree, unfortunately, is on matters that are quite fundamental, yet rather subtle. I'm finding myself having to explain quite a lot of this stuff, but there will still be many arguments in the book that I don't have the time or space to deal with.
Anyway, that's where my brain has gone, just at the moment. It'll be back.
