On finishing

Seneca wrote his letters to Lucilius near the end of his life, after Nero had pushed him from the center of Roman power toward retirement and, eventually, a forced death. He was an old man taking stock, walking his own aging estate, noticing which trees he had planted and which had grown wild. The letters are the work of someone deliberately closing accounts: not rushing, but treating each day as something that could stand complete on its own, whole rather than merely unfinished.

This week the novelist Colson Whitehead published Cool Machine, the third and final book of his Harlem Trilogy, following the furniture dealer Ray Carney out of the 1970s and into 1980s New York. It is the end of a project he has carried across years and three separate novels. There is a particular difficulty in finishing something long: the temptation to keep adding, to defer the ending, to treat completion as a kind of small death. Seneca's counsel cuts the other way. A thing brought to a close is not diminished. It is made whole.
