Painting from nature is not copying the object, it is realizing sensations. - Paul Cézanne

In that Renaissance (Cellini, Tintoretto, Titian..) there was an explosion of unique truthfulness, a love of painting and form.. .Then come the Jesuits and everything is formal; everything has to be taught and learned. It required a revolution for nature to be rediscovered; for Delacroix to paint his beach at Etratat, Corot his roman rubble, Gustave Courbet his forest scenes and his waves. And how miserable slow that revolution was, how many stages it had to go through!.. .These artists had not yet discovered that nature has more to do with depth than with surfaces. I can tell you, you can do things to the surface.. ..but by going deep you automatically go to the truth. You feel a healthy need to be truthful. You'd rather strip your canvas right down than invent or imagine a detail. You want to know.

Monet's cliffs (at Etretat) will survive as a prodigious series, as will a hundred others of his canvases.. .He'll be in the Louvre, for sure, alongside Constable and Turner. Damn it, he's even greater. He painted the iridescence of the earth. He's painted water. Remember those Rouen cathedrals.. .But where everything slips away in these pictures of Monet's, nowadays we must insert a solidity, a framework..

There is, in a apple, in a head, a culminating point, and this point - in spite of the effect, the tremendous effect: shadow or light, sensations of colour - is always the one nearest to the eye. The edge of objects recede to another point placed on your horizon. This is my great principle, my conviction, my discovery. The eye must concentrate, grasp the subject, and the brain will find a means to express it..
