Barnes never starts with characters. ‘I start with a situation, a moral error, and then I ask who it happens to.’ He described books as animals, with a structural exoskeleton—‘You have the idea of head, body, tail’—and mushier insides that the author must fill in. For ‘The Sense of an Ending,’ he’d originally envisioned a book with a long body and short head—‘a 3:1 ratio of set-up to pay-off’—but, in the course of writing, the body had shortened and the head had lengthened.
The germ of the book was a series of e-mails he exchanged with his brother, Jonathan Barnes, a professor of ancient Greek philosophy. Julian had written to Jonathan in an attempt to excavate details of their shared history such as how their grandfather killed chickens. Jonathan had replied, ‘I don’t think much of memory as a guide to the past.’ Over several years, Julian considered his brother’s point-of-view, and ending up writing a book about time and the tendency of humans, as time accumulates, to narrate our lives into shapes that the primary sources, were we ever to consult them, might belie.
