“Today I was on the Rue Laffette where the art dealers are. There is so much of interest to see here. You know the things that you call 'the artistic' in art. The French possess to a high degree this sense of not having to bring everything to a pitch of perfection. The mobility in their nature really comes to their aid there. We Germans always obediently paint our pictures from top till bottom, and are much to ponderous to do the little oil-sketches and improvisations which so often say more than a finished painting.”
