Any system which allows men to choose their own future will end by choosing safety and mediocrity, and in such a Reality the stars are out of reach.
Isaac AsimovEvery period of human development has had its own particular type of human conflict---its own variety of problem that, apparently, could be settled only by force. And each time, frustratingly enough, force never really settled the problem. Instead, it persisted through a series of conflicts, then vanished of itself---what's the expression---ah, yes, 'not with a bang, but a whimper,' as the economic and social environment changed. And then, new problems, and a new series of wars.
