"The commitment I have made is terrible and the plastic means appear and disappear at the moment of implementation. It's terrible.. .And the chaos of will? What law? It’s terrible.. .Then I struggle with sculpture: I work, work and work and I don't know what I give. Is it interior? Is it exterior? Is it sensation? Is it delirium? Is it brain? Analysis? Synthesis? I don't know what the f... it is! Forms on forms.. confusion.. .The Cubists are wrong. Picasso is wrong. The academics are wrong. We're all a bunch of d..heads."

“While the impressionists make a table to give one particular moment and subordinate the life of the table to its resemblance to this moment, we synthesize every moment and thus build the table.”

“'The street enters the house'.”

“..continued to paint objects motionless, frozen, and all the static aspects of Nature; they worship the traditionalism of w:Poussin, of w:Ingres, of Corot, ageing and petrifying their art with an obstinate attachment to the past, which to our eyes remains totally incomprehensible.”

“A horse in movement is not a stationary horse that moves but a horse in a movement, which is to say something other, that should be conceived and expressed as something completely different. It is a question of conceiving objects in movement over and above the motion they carry within themselves. That is, a question of finding a form which is the expression of this new absolute.. .A question of studying the aspects that life has taken on in haste and in consequent simultaneity.”

“With this new tendency the Cubists dubbed Impressionism of forms according to Appolinaire, is entering a final and glorious phase: ..Orphism, pure painting, simultaneity. And there you have it, as many obvious plagiarisms of what has formed, from its earliest appearances, the essence of Futurist painting and sculpture.. ..But we insist on sorting things out. Orphism , let us say it right away, is just an elegant masquerade of the basic principles of Futurist painting. This new trend simply illustrates the profit that our French colleagues managed to driver from our first Futurist exhibition in Paris.”

“Let us explain again by examples. In painting a person on a balcony, seen from inside the room do not limit the scene to what the square of the window renders visible; we try to render the sum total of visual sensations which the person on the balcony has experienced; the sun-baked throng in the street, the double row of houses which stretch to right and left, the beflowered balconies etc. This implies the simultaneity of the ambient, and, therefore, the dislocation and the dislocation and dismemberment of objects, the scattering and fusion of details, freed from accepted logic and independent from one another. In order to make the spectator live in the center of the picture, as we express it in our manifesto the picture must be the synthesis of what one remembers and what one sees. You must render the invisible which stirs lives beyond intervening obstacles, what we have on the right, or the left, or behind us, and not merely the small square of life artificially compressed, as it were, by the wings of a stage set. We have declared in our manifesto that what must be rendered is the dynamic sensation, that is to say, the particular rhythm of each object, its inclination, its movement, or more exactly, its interior force.”
