It seems that the first argument made here last fall by Godlessons, in which he argued that there is a contradiction between God’s omniscience (at least if that means knowing the future perfectly) and his omnipotence, is one put forward by Richard Dawkins in The God Delusion. All this time I thought it was just a very silly argument made up by some unthinking dude on the internet when it turns out instead that it’s “a very weak challenge coming from a superior intellect,” to quote Greg Koukl.
