Jason couldn't go to sleep. He couldn't quit thinking about the Principle. What had started him to thinking on it he did not know, and as an exercise that might shake him loose from it, he tried to backtrack in his mind to the point where he had first begun his speculations, but the area was fogged and he could not get to the beginning of it and the wondering went on.
He should get to sleep, he told himself. Thatcher would wake him early in the morning and with John he'd set off down the path to Horace Red Cloud's camp. He looked forward to traveling up the river, for it would be interesting—it had been a long time since he had gone far from home—but no matter how interesting it might be, it would be a hard day for him and he needed sleep.
He tried counting sheep and tried adding a column of imaginary figures, but the sheep refused to jump and the figures faded off into the nothingness from which he'd summoned them and he was left with the worry and the wonder of the Principle.
If the universe were steady-state, if it had no beginning and would not have an end, if it had always existed and would continue to exist, at what point in this foreverness had the Principle come into being—or was it, as well as the universe, a foreverness? And if the universe were evolutionary, starting at a certain time and place and destined to come to an end at a certain time and place, had the Principle been there and waiting, a strangeness out of nothingness, or had it evolved only at a later time and from what had it evolved? And why this galaxy, he wondered—why had the Principle chosen to reside within this galaxy, when there were billions of other galaxies that could have been its home? Had it come into being in this galaxy and stayed here, and if that should be the case, what unique characteristics did this galaxy offer to trigger its appearance? Or was it a much larger thing than anyone might imagine, was the manifestation of it in this galaxy only an outpost of a much greater central unity?
It was all absurd, of course. There was no way in which he could find an answer; no means by which he could arrive at even a logical suspicion of what had really happened. He didn't have the data; no one had the data. The only one that would know would be the Principle itself. The whole procedure of his thinking, Jason knew, was an imbecilic exercise; there was no compelling reason for him to seek an answer. And yet his mind bored on and on and he could not stop it, hanging with desperation to an impossibility to which it never should have paid attention.
He turned over restlessly and tried to burrow his head deeper into the pillow.
"Jason," said Martha, out of the darkness, "are you asleep?"
He mumbled to her. "Almost," he said. "Almost."
