"Paul Gauguin, that curious artist, that alien whose mien and the look in whose eyes vaguely remind one of Rembrandt's 'Portrait of a Man' in the Galerie Lacaze — this friend of mine likes to make one feel that 'a good picture is equivalent to a good deed'; not that he says so, but it is difficult to be on intimate terms with him without being aware of a certain moral responsibility. A few days before we parted, when illness forced me to enter an asylum, I tried to paint 'his empty place'. It is a study of his armchair of dark, red-brown wood, the seat of greenish straw, and in the absent person's place a lighted candlestick and some modern novels."

"Gauguin, if he'll accept it, you [Theo] shall give him a version of the [painting] 'Berceuse' (see:https://commons.wikimedia.org/wiki/File:La_Berceuse.jpg that wasn't mounted on a stretching frame, and to Bernard too, as a token of friendship. But if Gauguin wants sunflowers it's only absolutely fair that he gives you something that you like as much in exchange. Gauguin himself above all liked the sunflowers later, when he had seen them for a long time."

"Gauguin interests me very much as a man — very much. For a long time now it has seemed to me that in our nasty profession of painting we are most sorely in need of men with the hands and the stomachs of workmen. More natural tastes — more loving and more charitable temperaments — than the decadent dandies of the Parisian boulevards have. Well, here we are without the slightest doubt in the presence of a virgin creature with savage instincts. With Gauguin blood and sex prevail over ambition."

"[..according to Gauguin] the impression of nature must be wedded to the aesthetic sentiment which chooses, arranges, simplifies and synthesizes. The painter ought not to rest until he has given birth to the child of his imagination.. ..begotten in a union of his mind with reality. Gauguin insisted on a logical construction of composition, on a harmonious apportionment of light and dark colors, the simplification of forms and proportions, so as to endow the outline's of forms with a powerful and eloquent expression.. ..He also insisted upon luminous and pure colors."
