On presentiment

Our narrator, and in this instance I am sure the author too, explains the nature of presentiment, which is fine if you forget all the instances when it has no effect.  Expressed far more elegantly by Proust, of course:

“I should very much like, if you have such a thing, a photograph of the little picture of Miss Sacripant. ‘Sacripant’—that’s not a real name, surely?” “It is the name of a character the sitter played in a stupid little musical comedy.” “But, I assure you, sir, I have never set eyes on her; you look as though you thought that I knew her.” Elstir was silent. “It isn’t Mme. Swann, before she was married?” I hazarded, in one of those sudden fortuitous stumblings upon the truth, which are rare enough in all conscience, and yet give, in the long run, a certain cumulative support to the theory of presentiments, provided that one takes care to forget all the wrong guesses that would invalidate it.
