A painting or sculpture not modelled on any real object is every bit as concrete and sensuous as a leaf or a stone... but it is an incomplete art which privileges the intellect to the detriment of the senses.

To be full of joy when looking at an oeuvre is not a little thing.

The important thing about Dada, it seems to me, is that Dadaists despised what is commonly regarded as art, but put the whole universe on the lofty throne of art.

We attempted perfection; we wanted an object to be without flaw, so we cut the papers with a razor, pasted them down meticulously, but it buckled and was ruined... that is why we decided to tear prewrinkled paper, so that in the finished work of art imperfection would be an integral part, as if at birth death were built in.

I use very little red. I use blue, yellow, a little green, but especially... black, white and grey. There is a certain need in me for communication with human beings. Black and white is writing.
