"Next time round Hitler will be a machine, developed by male conquest as the most efficient method of subduing the peoples of the earth. Our only hope is that we have yet time to breed a generation which cannot be ruled in such a way or seek such a way to rule. We have no more need of great generals, for war is no longer fought by men but by machines against men. Machines are not mortal nor do they feel pain, so they must perforce win the war, unless the last of the fantasy heroes can acknowledge his weakness and his terror, and beg pardon."
