"We have reached that delightful moment when 'Impressionism' is about to be born, when its light is still only a hint, a caress, in the silvery snows of Monet or in the pale skies of Pissarro. Ah, how one would like to prolong this moment of hesitation for ever, this moment of transition, when transparent blue shadows are putting black shadows to flight and bitumen disappears!"

“My dear Duret, I went to see Monet yesterday. I found him heart-broken and completely on the rocks. He asked me to find him someone who would take from ten to twenty of his paintings at their choice, for 111 fr. apiece. Shall we do it between us, making 500 fr. each? Naturally, no one, least of all he, must know that it is we who are doing it..”

“You would hardly believe, my dear fellow, how difficult it is to clap a solitary figure on a canvas and to concentrate the entire interest on that one solitary figure without it ceasing to be lively and full.. .Your portrait is an outstandingly sincere work. I remember as though it were yesterday the rapid, summary fashion in which I dealt with the glove of the ungloved hand. And when you said to me, at that very moment, 'Please not another touch', I felt we were so perfectly attuned that I couldn't resist the impulse to embrace you. Ah! Heaven send that no one takes it into his head later on to stick that portrait into a public collection!”

“I was painting modern Paris while you were still painting Greek athletes..”

“You can do plein-air painting indoors, by painting white in the morning, lilac during the day and orange tones in the evening.”

“He has no talent at all, that boy! You, who are his friend, tell him please to give up painting.”

“Ah! Women.. .I met one yesterday on the Pont de l'Europe . She was walking the way only a Parisienne knows how to walk, but with an extra something, even more assured. I'll remember that. There are some things that will always be engraved on my mind.”
