They were the misfits of the world, the outcasts, for they deviated from the norm of humanity as established through all of history. Yet it was this very deviation which made them the hope of all mankind. Ordinary human beings—the kind of human beings who had brought the race this far—were not enough today. The ordinary humans had pushed the culture forward as far as they could push it. It had served its purpose; it had brought the ordinary human as far as he could go. Now the race evolved. Now new abilities had awoke and grown—exactly as the creatures of the Earth had evolved and specialized and then evolved again from that first moment when the first feeble spark of life had come into being in the seething chemical bath of a new and madcap planet.
Twisted brains, the normal people called them; magic people, dwellers of the darkness—and could anyone say no to this? For each people set its standards for each generation and these standards and these norms were not set by any universal rule, by no all-encompassing yardstick, but by what amounted to majority agreement, with the choice arrived at through all the prejudice and bias, all the faulty thinking and the unstable logic to which all intelligence is prone.
