Chekhov once said, “Art doesn’t have to solve problems, it only has to formulate them correctly.” “Formulate them correctly” might be taken to mean: “make us feel the problem fully, without denying any part of it.

When a writer subjects us to a non-normative event—a physical implausibility, the use of markedly elevated language (or markedly vernacular language), or a series of lengthy digressions in a Russian pub in which the people keep freezing in midaction for several pages so that each can be described at length, in turn—he pays a price: our reading energy drops. (We get suspicious and resistant.) But if it doesn’t drop fatally, and if, later, we see that this was all part of the plan—if what seemed a failure of craft turns out to be integral to the story’s meaning (that is, it seems that he “meant to do that”)—then all is forgiven and we might even understand the profitable exploitation of that apparent excess as a form of virtuosity.

This is a big moment for any artist (this moment of combined triumph and disappointment), when we have to decide whether to accept a work of art that we have to admit we weren’t in control of as we made it and of which we’re not entirely sure we approve. It is less, less than we wanted it to be, and yet it’s more, too—it’s small and a bit pathetic, judged against the work of the great masters, but there it is, all ours.

And let’s note that we’re only asking these questions (which, in turn, are causing the story to ask questions about the nature of love) because the length of each relationship was specified by the story and because Chekhov “remembered” or “took the trouble” to vary this parameter.

Gogol was a strange creature,” Nabokov wrote, “but genius is always strange; it is only your healthy second-rater who seems to the grateful reader to be a wise old friend, nicely developing the reader’s own notions of life.” Tolstoy and Chekhov, Nabokov said, also had their “moments of irrational insight” that produced an abrupt moment of “focal shift,” but in Gogol “this shifting is the very basis of his art.
