“Art furnishes us with eyes and hands and above all the good conscience to be able to turn ourselves into such a phenomenon.”

1984, p. 5
L’Art Corporel, 1979

Nobel lecture (1970)
Context: We, holding Art in our hands, confidently consider ourselves to be its masters; boldly we direct it, we renew, reform and manifest it; we sell it for money, use it to please those in power; turn to it at one moment for amusement — right down to popular songs and night-clubs, and at another — grabbing the nearest weapon, cork or cudgel — for the passing needs of politics and for narrow-minded social ends. But art is not defiled by our efforts, neither does it thereby depart from its true nature, but on each occasion and in each application it gives to us a part of its secret inner light.

Variant: Art enables us to find ourselves and loose ourselves at the same time.

Context: By art alone we are able to get outside ourselves, to know what another sees of this universe which for him is not ours, the landscapes of which would remain as unknown to us as those of the moon. Thanks to art, instead of seeing one world, our own, we see it multiplied and as many original artists as there are, so many worlds are at our disposal, differing more widely from each other than those which roll round the infinite and which, whether their name be Rembrandt or Vermeer, send us their unique rays many centuries after the hearth from which they emanate is extinguished.This labour of the artist to discover a means of apprehending beneath matter and experience, beneath words, something different from their appearance, is of an exactly contrary nature to the operation in which pride, passion, intelligence and habit are constantly engaged within us when we spend our lives without self-communion, accumulating as though to hide our true impressions, the terminology for practical ends which we falsely call life.

I Think I'll Sit This One Out (1939)
Context: Socialism may be all right when men are fit to be socialists. The way may be hard and slow, but until we take it we shall find that the so-called Socialist state degenerates and Fascism as rapidly as the pacifist with warm hearts to generate into militarists with fevered brows.
Marxism, like fascism and capitalism is materialism. The love of material goods above all others is as animal as of love of war. The love of justice above material goods must save us in the end it saved we may be.
