"Already in 1915, Sophie Taeuber [his wife] divides the surface of her aquarelle into squares and rectangles which she then juxtaposes horizontally and perpendicularly [as Mondrian, Itten and Paul Klee did in the same period]. She constructs them as if they were masonry work. The colors are luminous, ranging from the raw yellow to deep red or blue."

"Automatic poetry comes straight out of the poet's bowels or out of any other of his organs that has accumulated reserves.. .He crows, swears, moans, stammers, yodels, according to his mood.. .His poems are like nature; they stink, laugh, and rhyme like nature. Foolishness, or at least what men calls foolishness is as precious to him as a sublime piece of rhetoric. For in nature a broken twig is equal in beauty and importance to the clouds and the stars."

"Structures of lines, surfaces, forms, colours. They try to approach the eternal, the inexpressible above men. They are a denial of human egotism. They are the hatred of human immodesty, the hatred of images, of paintings.. Wisdom [is] the feeling for the coming reality, the mystical, the definite indefinite, the greatest definite."

"I wanted to find another order, another value for man in nature. He should no longer be the measure of all things, nor should everything be compared with him, but, on the contrary, all things, and man as well, should be like nature, without measure. I wanted to create new appearances, to extract new forms from man. This is made clear in my objects from 1917."

"We do not wish to copy nature. We do not want to reproduce, we want to produce. We want to produce as a plant produces a fruit and does not itself reproduce. We want to produce directly and without meditation. As there is not the least trace of abstraction in this art, we will call it concrete art."

"Dada was given the Venus of Milo a clyster and has allowed the Laocoön and his sons to rest awhile, after thousands of years of struggle with the good sausage Python. The philosophers are of less use to Dada than an old toothbrush, and it leaves them on the scrap heap for the great leaders of the world."

"I tried to be natural, in other words the exact opposite of what drawing teachers call 'faithful to nature'. I made my first experiments with free form."

"By the time I was 16, the everlasting copying of stuffed birds and withered flowers at the Strasbourg School of Applied Art not only poisoned drawing for me but destroyed my taste for all artistic activity. I took refuge in poetry."

"It was Sophie [Taeuber] who, by the example of her work and her life, both of them bathed in clarity, showed me the right way. In her world, the high and the low, the light and the dark, the eternal and the ephemeral, are balanced in prefect equilibrium."

"In 1915 Sophie Taeuber and I carried out our first works in the simplest forms, using painting, embroidery and pasted paper [without using oil colors to avoid any reference with usual painting]. These were probably the first manifestations of their kind, pictures that were their own reality, without meaning or cerebral intention. We rejected everything in the nature of a copy or a description, in order to give free flow to what was elemental and spontaneous."

"A deep and serene silence filled her structures composed of colors and surfaces. The exclusive use of horizontal and vertical rectangular planes in the work of art, the extreme simplification, exerted a decisive influence on my work. Here I found, stripped down to the limit, the essential elements of all earthly constructions: the bursting, upward surge of the lines and the planes toward the sky, the verticality of pure life, and the vast equilibrium, the sheer horizontality and expansiveness of dreamlike peace. Her work was for me a symbol of a divinely built 'house' which man in his vanity has ravaged and sullied."

"The man who speaks and writes about art should refrain from censuring or pontificating. He will thus avoid doing anything foolish, for in the presence of primordial depth all art is but dream and nature."
