Portraiture may be all right for a man in his youth, but after forty I believe that manual dexterity deserts one, and, besides, the color-sense is less acute. Youth can better stand the exactions of a personal kind that are inseparable from portraiture. I have had enough of it".
• "Make the best of an emergency".
• "It is certain that at certain times talent entirely overcomes thought or poetry".
• "A person with normal eyesight would have nothing to know in the way of 'Impressionism' unless he were in a blinding light or in the dusk or dark".
