It was the desire for living, vital expression…. which built Gothic cathedrals, which created Mozart sonatas. I believe it is going to stay that way for long time to come.
The new discovery that I have made in painting is the following. There are chords of colors, let's say a certain red and green, which move, shimmer when you look at them. Now if you're looking at a tree in a landscape, you can either look at the tree, or at the landscape, but not both, because of the stereoscopic effect. Now, when you are painting something three-dimensional, the chromatic sound which shimmers is the three-dimensional effect of colour, and when you paint a landscape, and the green foliage shimmers a little with the blue sky showing through it, that happens because the green is on a different plane from the sky in nature too. Finding the space-shaping energies of colour, instead of contenting ourselves with a dead chiaroascuro, is our finest task.
Cubism, Futurism, Expressionism, abstract painting, are only names given to a change which our artistic thinking wants to make and is thinking. Nobody has ever painted fallen raindrops suspended in the air, they've always been depicted as streaks (even the cave-men drew herds of reindeer in the same way). Now people are painting cabs rattling, lights flickering, people dancing, all-in the same way (this is how we all see movement). That is thew whole frightfully simple secret of Futurism. Its very easy to prove its artistic feasibility, for all the philosophizing that has been raised against it. Space, surface and time are different things, which ought not to be mixed together, is the continuous cry. If only it were possible to separate them. I can't do it.
