'Art or anti-art?' was the question I asked when I returned from Munich in 1912 and decided to abandon pure painting or painting for its own sake. I thought of introducing elements alien to painting as the only way out of a pictorial and chromatic dead end.

Everything important that I have done can be put into a little suitcase.

All painting, beginning with Impressionism, is antiscientific, even Seurat. I was interested in introducing the precise and exact aspect of science, which hadn't often been done, or at least hadn't been talked about very much.
