As the months of agony advanced, there was bred in the warring peoples a genuine and even passionate will for peace and a united world. Out of the conflict of the tribes arose, at least for a while, a spirit loftier than tribalism. But this fervour lacked as yet clear guidance, lacked even the courage of conviction.

Socrates woke to the ideal of dispassionate intelligence, Jesus to the ideal of passionate yet self-oblivious worship. Socrates urged intellectual integrity, Jesus integrity of will. Each, of course, though starting with a different emphasis, involved the other.
Unfortunately both these ideals demanded of the human brain a degree of vitality and coherence of which the nervous system of the First Men was never really capable.

Today we should welcome, and even study, every serious attempt to envisage the future of our race; not merely in order to grasp the very diverse and often tragic possibilities that confront us, but also that we may familiarize ourselves with the certainty that many of our most cherished ideals would seem puerile to more developed minds. To romance of the far future, then, is to attempt to see the human race in its cosmic setting, and to mould our hearts to entertain new values.
