If this particular book is not giving me pleasure now, it may give me pleasure later, if I allow it to do so. Maybe it’s just starting slowly but will pick up speed; maybe I haven’t fully grasped the idiom it’s working in but eventually will figure it out; maybe the problem is not with the book but with my own powers of concentration because I slept fitfully last night….

Many maybes. But in any case, I have to decide whether to persevere, and for a long time my default position was to continue. Indeed, I was twenty years old before I failed to finish a book I had started: it was The Recognitions, a novel by William Gaddis, and I gave up, after an extended period of moral paralysis, at page 666. That day I grieved, feeling that I had been forced from some noble pedestal; but I woke up the next morning with my soul singing. After all, though I would never get back the hours I had devoted to those 666 pages, the hours I would have spent ploughing through the remaining four hundred were mine to spend as I would. I had been granted time as a pure and sweet gift.

Of course, once you have abandoned a book after more than six hundred pages, abandoning one after fifty seems trivial. But for me that wasn’t a bad thing. I needed to overcome the sense of duty that had marched me through so many books before the ultimately liberating, if at the time miserable, experience of The Recognitions; and I needed to learn, as I eventually did, that if I set a book aside today I am not thereby forbidding myself to return to it later — nor am I promising to do so.
