"Art alone makes life possible – this is how radically I should like to formulate it. I would say that without art man is inconceivable in physiological terms."

“This is precisely what the shaman does in order to bring about change and development: his nature is therapeutic.”

“Even the act of peeling a potato can be an artistic act if it is consciously done.”

“In discussing his work it is necessary to avoid overrating his silence. I hold him in a very high esteem, but I have to reject his silence. Duchamp was simply finished. He had run out of ideas; he was unable to come up with anything important.. .I would say that even the bourgeois tendencies in Duchamp's work – i.e., a form of provocative, bohemian behavior intended to 'épater le bourgeois'- follow the same path. Duchamp started out from here and wanted to shock the bourgeoisie, and because of that he destroyed his creative powers.. .The content of Duchamp's silence refers to the aim of leaving the subconscious passive, of developing it. This is the aspect of Duchamp, which is related to Surrealism. The surrealists asserted that they could live with their subconscious; they thought they were above reality, but instead they were beneath it. They thought they could fish in muddy waters.. ..but to my mind, the images which emerged have a repressive effect.”

“Directly after the interviews his holiness the 14th Dalai Lama of Tibet had given me in Dharamsala, I enthusiastically informed Joseph Beuys how struck I was by the similarity in the viewpoint of His Holiness the Dalai Lama and the ideas that he himself had been working towards in his 'Social Sculpture' for the last fifteen years. I was able to come to this conclusion because my questions in the first interview with his Holiness had for a large part been inspired by the subjects Joseph Beuys had put to discussion first through his 'Organisation for a Direct Democracy', and then through his 'Free international University,' the ecological 'Green movement' and the political party 'The Greens'. The immediate reply from Joseph Beuys to my remark was that 'he would very much want to set up a permanent co-operation with His Holiness the Dalai Lama'.”

“My intention: healthy chaos, healthy amorphousness in a known medium which consciously warmed a cold, torpid form from the past, a convention of society, and which makes possible future forms.”

“He asked me for my participation and I rejected the plan to make a kind of sculpture there in this old way, to make in a kind of special place this special modern sculpture. I told him that my idea would be this time to plant seven thousand oaks in Kassel, seven thousand trees. And to mark every tree with a little stone, so that everybody after three, two, five or six hundred years can still see that in 1982 there was an activity. After the radical destruction of the forests here in Germany for all this technological nonsense, that there was an impulse that came in the same time, to plant seven thousand oaks. This is such a kind of activity during the Documenta , that has to do with the 'Documenta', but is a real other thing in the conventional understanding of art.”
