"All religions must, at their core, look forward to the end of this world and to the longed-for moment when all will be revealed and when the sheep will be divided from the goats, or whatever other bucolic Bronze-Age desert analogy might seem apt. (In Papua New Guinea, where as in most tropical climes there are no sheep, the Christians use the most valued animal of the locals and refer to the congregation as "swine." Flock, herd: what difference does it make?) Against this insane eschatology, with its death wish and its deep contempt for the life of the mind, atheists have always argued that this world is all that we have, and that our duty is to one another to make the very most and best of it. Theism cannot coexist with this unexceptionable conclusion."
