And then, as you can see, I give greater and greater importance to the materials I use in my work [c. 1936]. A rich and vigorous material seems necessary to me in order to give the viewer that smack in the face that must happen before reflection intervenes. In this way, poetry is expressed through a plastic medium, and it speaks its own language.

... the fact is, they are sculptures, since they show the relationship of object to object and that is the idea and purpose of a sculpture. I’ve got nothing against ‘poetry,’ but it’s only resonance and tempo. Each of my works is perhaps also indeed a poetic sculpture. It’s not that I think it’s a bad word, poetry, but I’m not a poet, since a poet is concerned with the relationship of human beings to human beings.

Architecture is treated as crystallisation; sculpture, as the organic modelling of the material in its sensuous and spatial totality; painting, as the coloured surface and line; while in music, space, as such, passes into the point of time possessed of content within itself, until finally the external medium is in poetry depressed into complete insignificance.

The relationship of volumes, lines, and colors demands absolute orchestration and order. These values are all unquestionable influential; they have extended into modern objects such as airplanes, automobiles, farm machines, etc. Today we are in competition with the 'beautiful object'; it is undeniable. Sometimes its plastic qualities make it beautiful in itself and consequently unusable; one can only fold one's arms and admire it. There is also today an astonishing art of window display. Certain store windows are highly organized spectacles.. .If, pushing things to extremes, the majority of manufactured objects and 'stored spectacles' were beautiful and had plasticity, we artists would no longer have any reason to exist.

A thought that has found a plastic expression must continue to expand in keeping with its own plastic idiom. A plastic idea must be expressed with plastic means just as a musical idea is expressed with musical means, or a literary idea with verbal means. Neither music nor literature are wholly translatable into other art forms; and so a plastic art cannot be created through a superimposed literary meaning. The artist who attempts to do so produces nothing more than a show-booth. He contents himself with visual story-telling. He subjects himself to a mechanistic kind of thinking which disintegrates into fragments.

Sculpture and painting are moments of life. Poetry is life itself.

Light and space ... are the sculptor's materials as much as wood or stone ... I feel that I can relate my work more easily, in the open air, to the climate and the landscape.

The philosophy which underlines my work is based on change, continuity and the search for measures in natural order. The value of a sculpture relies on its own existence through time, independent of its creator and should usually speak for itself. It should beckon you to walk into its space, to travel its surface and edge, to sense, to touch, to peer into and ponder. As you leave it should invite you to return another time so that it can communicate further.

I approach each building as a sculptural object, a spatial container, a space with light and air, a response to context and appropriateness of feeling and spirit. To this container, this sculpture, the user brings his baggage, his program, and interacts with it to accommodate his needs. If he can't do that, I've failed.
