“The Vinteuil sonata could tell Swann of the charm of certain nights in the Bois de Boulogne, about which it would have been pointless to ask Odette, although she had been no less with him on those nights than the little phrase. But she had only been sitting beside him (whereas the theme by Vinteuil was inside him); and even if she had been gifted with vastly greater understanding, she would have been unable to see what cannot be externalized for anyone”
