Marcel Duchamp
French Artist
Since Courbet, it's been believed that painting is addressed to the retina. That was everyone's error. The retinal shudder! Before, painting had other functions: it could be religious, philosophical, moral... our whole century is completely retinal, except for the Surrealists, who tried to go outside it somewhat.
Quote examples
Marcel Duchamp
French Artist
The last hundred years have been retinal; even the cubists were. The surrealists tried to free themselves, and earlier so had the dadaists, but unfortunately, these latter were nihilists and didn't produce enough to prove their point, which, by the way, they didn't have to prove - according to their theory.

Marcel Duchamp
French Artist
In French, there is an old expression, la patte, meaning the artist's touch, his personal style, his 'paw'. I wanted to get away from la patte and from all that retinal painting.
