The Messiah will be on In Our Time to discuss the evolutionary origins of altruism. They are pretty good about getting the archive up in a day or so. Interesting that they illustrate the idea with Mr. a priori Kant, or am I being pretentious and misunderstanding Kant? I simply suspect that Dawkins will argue and elucidate an evolutionarily beneficial situationalism.
Matthew 10:34 “Think not that I am come to send peace on earth: I came not to send peace, but a sword.”
