He was sketching out notes for a series of hypotheses which led to a coherent theory of Simultaneity. But that began to seem a petty goal; there was a much greater one, a unified theory of Time, to be reached, if he could just get to it. He felt that he was in a locked room in the middle of a great open country: it was all around him, if he could find the way out, the way clear. The intuition became an obsession. During that autumn and winter he got more and more out of the habit of sleeping. A couple of hours at night and a couple more sometime during the day were enough for him, and such naps were not the kind of profound sleep he had always had before, but almost a waking on another level, they were so full of dreams. He dreamed vividly, and the dreams were part of his work. He saw time turn back upon itself, a river flowing upward to the spring. He held the contemporaneity of two moments in his left and right hands; as he moved them apart he smiled to see the moments separate like dividing soap bubbles. He got up and scribbled down, without really waking, the mathematical formula that had been eluding him for days. He saw space shrink in upon him like the walls of a collapsing sphere driving in and in towards a central void, closing, closing, and he woke with a scream for help locked in his throat, struggling in silence to escape from the knowledge of his own external emptiness.

On a cold afternoon late in winter he stopped in at the physics office on his way home from the library to see if there were any letters for him in the pickup box. He had no reason to expect any, since he had never written any of his friends at Northsetting Regional; but he hadn’t been feeling very well for a couple of days; he had disproved some of his own most beautiful hypotheses and brought himself after half a year’s hard work right around to where he had started from, the phasic model was simply too vague to be useful, his throat felt sore, he wished there was a letter from somebody he knew, or maybe somebody in the physics office to say hello to, at least. But nobody was there except Sabul.

“Look here, Shevek.”

He looked at the book the older man held out: a thin book, bound in green, the Circle of Life on the cover. He took it and looked at the title page: “A Critique of Atro’s Infinite Sequency Hypothesis.” It was his essay, Atro’s acknowledgment and defense, and his reply. It had all been translated or retranslated into Pravic, and printed by the PDC presses in Abbenay. There were two authors’ names: Sabul, Shevek.

Sabul craned his neck over the copy Shevek held, and gloated. His growl became throaty and chuckling. “We’ve finished Atro. Finished him, the damned profiteer! Now let them try to talk about ‘puerile imprecision’!” Sabul had nursed ten years’ resentment against the Physics Review of Ieu Eun University, which had referred to his theoretical work as “crippled by provincialism and the puerile imprecision with which Odonian dogma infects every area of thought.” “They’ll see who’s provincial now!” he said, grinning. In nearly a year’s acquaintance Shevek could not recall having seen him smile.
