If we study Japanese art, you see a man who is undoubtedly wise, philosophic and intelligent who spends his time how? In studying the distance between the earth and the moon? No. In studying the policy of Bismarck? No. He studies a single blade of grass..

Recently I've been working very hard and quickly; in this way I try to express the desperately fast passage of things in modern life.

Yesterday, in the rain, I painted a large landscape with fields as far as the eye can see, viewed from a height, different kinds of greenery, a dark green field of potatoes, the rich purple earth between the regular rows of plants, to one side a field of peas white with bloom, a field of clover with pink flowers and the little figure of a mower, a field of tall, ripe, fawn-coloured grass, then some wheat, some poplars, on the horizon a last line of blue hills at the foot of which a train is passing, leaving an immense trail of white smoke over the greenery. A white road crosses the canvas, on the road a little carriage and some white houses with bright red roofs alongside a road. Fine drizzle streaks the whole with blue or grey lines.

I have [drawings of] about twelve figures of diggers and men who are working in a potato field, and I wonder if I could not make something of it, you have still a few, for instance, a man who fills a bag with potatoes. Well, I do not know for sure, but sooner or later I shall accomplish that, for I looked at it so attentively this summer, and here in the dunes I could make a good study of the earth and the sky, and then boldly put in the figures.

Now I'm working on [a painting of the hospital ward. In the foreground a big black stove around which a few grey or black shapes of patients, then behind the very long ward, tiled with red with the two rows of white beds, the walls white, but a lilac or green white, and the windows with pink curtains, with green curtains, and in the background two figures of nuns in black and white. The ceiling is violet with large beams. I had read an article on Dostoevsky, who had written a book, 'Souvenirs de la maison des morts' and that spurred me on to begin work again on a large study that I'd begun in the fever ward in Arles. But it's annoying to paint figures without models. I've read another of Carmen Sylva's ideas, which is very true: when you suffer a lot – you see everybody at a great distance, and as if at the far end of an immense arena – the very voices seem to come from a long way off. I've experienced this in these crises to such a point that all the people I see then seem to me, even if I recognize them – which isn't always the case – to come from very far away and to be entirely different from what they are in reality..

And although it was in a hospital that she lay and I sat next to her — it is always that eternal poetry of Christmas night with the infant in the stable, as the old Dutch painters conceived it and MIllet and Breton — a light in the darkness, the brightness in the middle of a dark night. And so I hung a large etching after Rembrandt over it, the two women by the cradle, one of them reading from the Bible by candlelight, while the great shadows cast a deep chiaroscuro over the whole room.

If one wants to be active, one mustn’t be afraid to do something wrong sometimes, not afraid to lapse into some mistakes. To be good — many people think that they’ll achieve it by doing no harm — and that’s a lie… That leads to stagnation, to mediocrity. Just slap something on it when you see a blank canvas staring at you with a sort of imbecility.

To stroll on wharves, and in alleys and in streets and in the houses, waiting-rooms, even saloons, that is not a pleasant pastime unless for an artist. As such, one would rather be in the dirtiest place where there is something to draw, than at a tea party with charming ladies. Unless one wants to draw ladies, then a tea party is all right even for an artist.

At present I have a portrait of a woman [Madame Roulin].. .Which I've called 'la berceuse', . .It's a woman dressed in green (bust olive green and the skirt pale Veronese green). Her hair is entirely orange and in plaits. The complexion worked up in chrome yellow, with a few broken tones, of course, in order to model. The hands that hold the cradle cord ditto ditto. The background is vermilion at the bottom (simply representing a tiled floor or brick floor). The wall is covered with wallpaper, obviously calculated by me in connection with the rest of the colours. This wallpaper is blue-green with pink dahlias and dotted with orange and with ultramarine.. .Whether I've actually sung a lullaby with colour I leave to the critics..
