I’ve added another engagement in London on 9 June: An evening with Richard Dawkins and PZ Myers. There will be a steel cage. Two enter, one leaves. We’ll settle who will be Emperor of the Atheists, finally.

Well, actually, it will just be a pleasant conversation, hosted by the British Humanist Association. If you’re interested in listening to chit-chat between two godless biologists who mostly agree on everything, get your tickets soon — they’ll probably sell out fast.
