What we cannot express by the art of thinking, by the art of Science o — Naum Gabo

"No new artistic system will withstand the pressure of a growing new culture until the very foundation of Art will be erected on the real laws of life. Until all artists will say with us... All is a fiction... only life and its laws are authentic and in life only the active is beautiful and wise and strong and right, for life does not know beauty as an aesthetic measure... efficacious existence is the highest beauty. Life knows neither good nor bad nor justice as a measure of morals... need is the highest and most just of all morals. Life does not know rationally abstracted truths as a measure of cognizance, deed is the highest and surest of truths. Those are the laws of life. Can art withstand these laws if it is built on an abstraction, on mirage, and fiction?..."

"[The Constructive idea..] has revealed a universal law that the elements of a visual art such as lines, colours, shapes, possess their own forces of expression independent of any association with the external aspects of the world; that their life and action are self-conditioned psychological phenomena rooted in human nature; that those elements are not chosen by convention by any utilitarian or other reason as words and figures are, they are not merely abstract signs, but they are immediately and organically bound up with human emotions. The revelation of this fundamental law has opened up a vast field in art giving the possibility of expression to those human impulses and emotions which have been neglected."

"Up to now sculptors have preferred the mass and neglected or paid little attention to such an important component of mass as space.. ..we consider it as an absolute sculptural element. I do not hesitate to affirm that the perception of space is a primary natural sense which belongs to the basic senses of our psychology"

"..adding Space perception to the perception of Masses, emphasizing it and forming it, we enrich the expression of Mass.. ..through the contrast between them whereby Mass retains its solidity and Space its extension."

"There is no indication of success up to now in the bringing together of art and science. To achieve success the artist must be spiritually at home in the field of science so he can think and feel in the same way as the scientist. A spiritual union, not a technical one, is requested."

"Science looks and observes and art see and foresees. Every great scientist has experienced a moment when the artist in him saved the scientist."
