"And he worked"

"Gradually the sunlight entered, shifted across the papers on the table, across his hands on the papers, and filled the room with radiance. And he worked. The false starts and futilities of the past years proved themselves to be groundwork, foundations, laid in the dark but well laid. On these, methodically and carefully but with a deftness and certainty that seemed nothing of his own but a knowledge working through him, using him as its vehicle, he built up the beautiful steadfast structure of the Principles of Simultaneity."

Ursula K. LeGuin, The Dispossessed
