New Athens was not a natural and spontaneous growth like the city whose name it bore. Everything about the Colony was deliberately planned, as the result of many years of study by a group of very remarkable men. It had begun as an open conspiracy against the Overlords, an implicit challenge to their policy if not to their power. At first the Colony’s sponsors had been more than half certain that Karellen would neatly frustrate them, but the Supervisor had done nothing — absolutely nothing. This was not quite as reassuring as might have been expected. Karellen had plenty of time: he might be preparing a delayed counterstroke. Or he might be so certain of the project’s failure that he felt no need to take any action against it.

That the Colony would fail had been the prediction of most people. Yet even in the past, long before any real knowledge of social dynamics had existed, there had been many communities devoted to special religious or philosophical ends. It was true that their mortality rate had been high, but some had survived. And the foundations of New Athens were as secure as modern science could make them. There were many reasons for choosing an island site. Not the least important were psychological. In an age of universal air transport, the ocean meant nothing as a physical barrier, but it still gave a sense of isolation. Moreover, a limited land area made it impossible for too many people to live in the Colony. The maximum population was fixed at a hundred thousand: more than that, and the advantages inherent in a small, compact community would be lost. One of the aims of the founders was that any member of New Athens should know all the other citizens who shared his interests — and as many as one or two per cent of the remainder as well.

The man who had been the driving force behind New Athens was a Jew. And, like Moses, he had never lived to enter his promised land, for the Colony had been founded three years after his death.

He had been born in Israel, the last independent nation ever to come into existence — and, therefore, the shortest lived. The end of national sovereignty had been felt here perhaps more bitterly than anywhere else, for it is hard to lose a dream which one has just achieved after centuries of striving.

Ben Salomon was no fanatic, but the memories of his childhood must have determined, to no small extent, the philosophy he was to put into practice. He could just remember what the world had been before the advent of the Overlords, and had no wish to return to it. Like not a few other intelligent and well-meaning men, he could appreciate all that Karellen had done for the human race, while still being unhappy about the Supervisor’s ultimate plans. Was it possible, he sometimes said to himself that despite all their enormous intelligence the Overlords did not really understand mankind, and were making a terrible mistake from the best of motives? Suppose, in their altruistic passion for justice and order, they had determined to reform the world, but had not realized that they were destroying the soul of man?

The decline had barely started, yet the first symptoms of decay were not hard to discover. Salomon was no artist, but he had an acute appreciation of art and knew that his age could not match the achievements of previous centuries in any single field. Perhaps matters would right themselves in due course, when the shock of encountering the Overlord civilization had worn off. But it might not, and a prudent man would consider taking out an insurance policy.

New Athens was that policy. Its establishment had taken twenty years and some billions of Pounds Decimal — a relatively trivial factor, therefore, of the world’s total wealth. Nothing had happened for the first fifteen years: everything had happened in the last five.

Salomon’s task would have been impossible had he not been able to convince a handful of the world’s most famous artists that his plan was sound. They had sympathized because it appealed to their egos, not because it was important for the race. But, once convinced, the world had listened to them and given both moral and material support. Behind this spectacular facade of temperamental talent the real architects of the Colony had laid their plans.

A society consists of human beings whose behaviour as individuals is unpredictable. But if one takes enough of the basic units, then certain laws begin to appear — as was discovered long ago by life-insurance companies. No one can tell what individuals will die in a given time — yet the total number of deaths can be predicted with considerable accuracy.

There are other, subtler laws, first glimpsed in the early twentieth century by mathematicians such as Weiner and Rashavesky. They had argued that such events as economic depressions, the results of armament races, the stability of social groups, political elections, and so on could be analyzed by the correct mathematical techniques. The great difficulty was the enormous number of variables, many of them hard to define in numerical terms. One could not draw a set of curves and state definitely: “When this line is reached, it will mean war.” And one could never wholly allow for such utterly unpredictable events as the assassination of a key figure or the effects of some new scientific discovery — still less such natural catastrophes as earthquakes or floods, which might haves profound effect on large numbers of people and the social groups in which they lived.
