He knew that he was very near achieving the General Temporal Theory that the Ioti wanted so badly for their spaceflight and their prestige. He knew also that he had not achieved it and might never do so. He had never admitted either fact clearly to anyone. Before he left Anarres, he had thought the thing was in his grasp. ... He wasn't quite sure he was ready to publish. There was something not quite right, something that needed a little refining. As he had been working ten years on the theory, it wouldn't hurt to take a little longer, to get it polished perfectly smooth. The little something not quite right kept looking wronger. A little flaw in the reasoning. A big flaw. A crack right through the foundations...The night before he left Anarres he had burned every paper he had on the General Theory. He had come to Urras with nothing. For half a year he had, in their terms, been bluffing them. Or had he been bluffing himself?
