I think you should all visit Martin's blog; I wish I had been there in Australia for this convention. I have never been to Australia and it's one of the places I'd like to visit. Martin comments on a talk by Sam Harris that certainly seemed very interesting. As you all know, I'm not crazy about Sam but he is an important figure for atheists and from what Martin says, his talk on death (he changed from "free will" to "death"; I'm glad he gave the free will thing a rest; death, we can all agree on: it exists) was very good. Martin wrote some good blogs on Sam's talk. Start here.
