"Then, from nowhere, we were invaded and utterly defeated by an alien people who used the precise laws of science we had scorned. Furthermore, we saw them ridicule our principles as semi-religious rituals of a savage culture. In the invasion less than a tenth of mankind survived. We were herded into the treaty areas, with no government and no real leadership. Some of us had been teachers before the war; the survivors looked to us to preserve the spirit and the ideals of man. "We had to make a selective choice, Lanny. We had no books, no written records, no way to preserve the whole of the past. The teachers in all the treaty areas quickly established contact by courier. The lesson of the invasion had taught us a great deal. Men had been imprisoned by one scientific dogma, which had produced a mechanized and neurotic world. The Almost-men were trapped by another that had produced the same end result. "So we had our first objective: to teach our children the supreme dignity, the magnificent godliness, of the rational mind. We didn't tell you what to think--which had been our mistake in the past--but simply the vital necessity of rational thought. We taught you that the mind was the integrating factor in the universe; everything else was chaos, without objectivity or direction, until it was controlled by mind. After that, we jammed your brains with data from every field of knowledge that had ever been explored by man. That's why we interchanged couriers so frequently. In our world we had been specialists; we had to share the facts among ourselves so the new breed might have them all." Far away they heard the dull thunder of an explosion. Lanny's head jerked up. Pendillo coughed up blood again, but there was a satisfied smile on his lips. "That will be Gill and the boys from the treaty area," he sighed. "Arriving right on schedule. We've forced them to attack the city without weapons; to survive, they'll have to make the same mental reintegration that you did, Lanny." "How could you have been so sure, father, that we would be able to--to handle the matter-energy units the way we do?" "We weren't, my son. We were sure of nothing. We only knew that you were the first generation whose minds had been set completely free. Nobody had done any of your thinking for you. If any man is equipped to solve problems, you are--you of the new breed." "But why couldn't you learn the same techniques yourselves? Why can't you save yourself now, father?" "Because we belong in the old world. Because the technique is only an application of the data you know, Lanny; that is something you have worked out for yourselves. We could give you the theory; we were incapable of following it through your minds."
