Mark O'Connell over at the Millions:
[T]hree or four years ago, something changed. For some reason I can’t recall (probably a longish lapse in productivity on my thesis) I set myself the task of reading a Great Big Important Novel. For another reason I can’t recall (probably the fact that it had been sitting on a shelf for years, its pages turning the sullen yellow of neglected great books), I settled on Gravity’s Rainbow. I can’t say that I enjoyed every minute of it, or even that I enjoyed all that much of it at all, but I can say that by the time I got to the end of it I was glad to have read it. Not just glad that I had finally finished it, but that I had started it and seen it through. I felt as though I had been through something major, as though I had not merely experienced something but done something, and that the doing and the experiencing were inseparable in the way that is peculiar to the act of reading. And I’ve had that same feeling, I realize, with almost every very long novel I’ve read before or since.
You finish the last page of a book like Gravity’s Rainbow and—even if you’ve spent much of it in a state of bewilderment or frustration or irritation—you think to yourself, “that was monumental.” But it strikes me that this sense of monumentality, this gratified speechlessness that we tend to feel at such moments of closure and valediction, has at least as much to do with our own sense of achievement in having read the thing as it does with a sense of the author’s achievement in having written it. When you read the kind of novel that promises to increase the strength of your upper-body as much as the height of your brow—a Ulysses or a Brothers Karamazov or a Gravity’s Rainbow—there’s an awe about the scale of the work which, rightly, informs your response to it but which, more problematically, is often difficult to separate from an awe at the fact of your own surmounting of it.
The upshot of this, I think, is that the greatness of a novel in the mind of its readers is often alloyed with those readers’ sense of their own greatness (as readers) for having conquered it. I don’t think William Gaddis’s The Recognitions, for instance, is nearly as fantastic a novel as people often claim it is. But it is one of the most memorable and monumental experiences of my reading life. And these are the reasons why: because the thing was just so long; because I had such a hard time with it; and because I eventually finished it.
