On Earth, gradually learned through trial and error, experimental colonists were not picked for their jobs because of flexible, incisive, or brilliant minds. Quite the contrary. The basic test of a successful colonist was endurance—the endurance of hardship, privation, the stoic indifference to conditions of discomfort, monotony, pain, uncleanliness, immodesty—conditions which would send a more imaginative or sensitive temperament into a downward-spiraling syndrome of failure. They were the kind of men and women who, on Earth in an earlier time, had been able to endure the harshness of the sea, of arctic cold, jungle disease, desert heat; to make those first steps in taming a hostile environment, so that men with less endurance, but with more delicately poised and sensitive minds, following them might then endure.

It was characteristic of such men and women, even under Earth conditions, that they seldom questioned their reasons for these things. They simply went, and endured, and tamed. Even on Earth, when the taming had been done, they moved on. This was the stuff of the experimental colonist.

Now, here, that temperament still persisted. They had fled in panic, but now they had returned to their original purpose—to endure. It was enough.

Louie was to learn, in disappointment, that failure to be curious about scientific reasoning was usually accompanied by an equal failure to be curious about philosophical implications. They listened idly to his exhortations, but their eyes did not light with fire nor cloud with doubt. They simply wandered away after a time and ate or slept.

In the evening of that second day, Cal sat with Tom and Jed down by the bank of the river where the sky was clear and the stars beginning to shine. They were talking quietly of home, of Eden, of the colonists who, more and more, seemed to take on the character of a contented herd of animals. So far there had been no attempt of the old males to drive the young ones out of the herd, destroy them, but that might come in time; as surely as the old males on Earth by tacit agreement on both sides, were always able to work up a war for the purpose of weeding out and destroying lusty young male competition.

They were talking of the curious fact that all three of them seemed able to continue thinking in a straight line, hold their minds to a subject, while all the rest grew more vague, less retentive, more content to live from moment to moment, without concern for past or future.

Except Louie. He too seemed able to hold his thinking in a straight line, one tangential to theirs. He seemed, in these hours, to have turned wholly mystical, to a stronger belief that they were being watched and cared for by some higher power, and that this was for a purpose. Yet not so tangential, for Cal had come to the same conclusion, although his interpretation differed.

"I can't doubt that there is an intelligent direction of this peculiar co-ordinate system," he said to Tom and Jed. "But I must doubt it is supernatural in the way Louie interprets. Anything appears to be magic when we don't understand how it happens, and becomes science when we do."

He paused, and looked at his companions' faces in the starshine. They were quiet, reposed, listening.

"Ever since man got up off the bottom of his ocean of air," he said, "and out into space, we've been prepared to run into some form of intelligence which doesn't behave the way we do. Not prepared to do anything about it, you understand," he said with a shrug. "Just theoretically prepared that it might happen. It was a possibility. Now it does seem to have happened. E McGinnis asked me, before I left Earth, if I thought Eden was an alluring trap, especially baited to catch some human beings. It begins to appear that it is."
