To speculate about whether Proust was a snob is as superfluous as debating the degree of Joyce’s egotism, though we could construct an argument that Proust would have been unfitted to dissect the society of Recherche without a social climber’s desire. And Joyce writing in A Portrait that the “artist, like the God of the creation, remains within or behind or beyond or above his handiwork, invisible, refined out of existence, indifferent, paring his fingernails” feels more like his defence of a narcissistic narrator than a personal attitude. Neither quality detracts from the brilliance of either writer, and arguably both characteristics are disproportionally present among writers of the time (or perhaps any time).
Both qualities are in the foreground of the story Joyce told Frank Budgen (Further Recollections of James Joyce, 1955) of being introduced to Proust at a supper party for Stravinsky and Diaghilev. “Our talk consisted solely of the word ‘No.’ Proust asked me if I knew the duc de so-and-so. I said, ‘No.’ Our hostess [although observers claim this question came from Joyce] asked Proust if he had read such and such a piece of Ulysses. Proust said, ‘No,’ And so on.”
Though the two men apparently sat beside each other and later shared a cab home, no written record exists of their encounter, though there is no shortage of biographical speculation about conversations about health and truffles.
