been here. Those of us who came first are almost like the people on Phaedra—some ways. The younger people are inclined to be suspicious of us because we ... try to guide them." "If you're confiding that you think there may be two sides to this war," Calhoun told her, "you are quite right. But see what your husband can do about gathering some of the hunting-and-fishing members of the community. I've got to get back to my ship." He got himself driven back to the landing-grid. Walker did not drive him, but another of the now-suspect men of twenty-five or so, from the shelter village of the first-landed colonists. He was one of those who'd worked with Walker from the beginning and with him had been most embittered. Now he found himself almost a member of an older generation. He was still bitter against the people of Phaedra, but— "This whole business is a mess!" he said darkly as he drove through the nearly deserted city toward the landing-grid. "We've got to figure out a way to organize things that'll be better than the old way. But no organization at all is no good, either! We've got some tough young characters who like it this way, but they've got to be tamed down!" Calhoun had his own unsettling suspicions. There have always been splendid ideas of social systems which will make earthly paradises for their inhabitants. Here, by happen-chance, there had come to be a world inhabited only by the young. He tried to put aside, for the moment, what he was unhappily sure he'd find out back at the ship. He tried to think about this seemingly perfect opportunity for a new and better organization of human lives. But he couldn't believe in it. Culture-instinct theory is pretty well worked out. The Med Service considered it proven that the basic pattern of human societies is instinctual rather than evolved by trial and error. The individual human being passes through a series of instinct-patterns which fit him at different times to perform different functions in a social organization which can vary but never change its kind. It has to make use of the successive functions its members are driven by instinct to perform. If it does not use its members, or give scope to their instincts, it cannot survive. The more lethal attempts at novel societies tried not only to make all their members alike, but tried to make them all alike at all ages. Which could not work. Calhoun thought unhappily of the tests he meant to make in the Med ship. As the ground-car swerved into the great
