A white square floating weightlessly in a white field, Suprematist Composition: White on White was one of the most radical paintings of its day: a geometric abstraction without reference to external reality. Yet the picture is not impersonal: we see the artist's hand in the texture of the paint, and in the subtle variations of the whites. The square is not exactly symmetrical, and its lines, imprecisely ruled, have a breathing quality, generating a feeling not of borders defining a shape but of a space without limits.

After the Revolution, Russian intellectuals hoped that human reason and modern technology would engineer a perfect society. Malevich was fascinated with technology, and particularly with the airplane, instrument of the human yearning to break the bounds of earth. He studied aerial photography, and wanted White on White to create a sense of floating and transcendence. White was for Malevich the color of infinity, and signified a realm of higher feeling.

For Malevich, that realm, a utopian world of pure form, was attainable only through nonobjective art. Indeed, he named his theory of art Suprematism to signify "the supremacy of pure feeling or perception in the pictorial arts"; and pure perception demanded that a picture's forms "have nothing in common with nature." Malevich imagined Suprematism as a universal language that would free viewers from the material world.
