I have observed among the pictures submitted here quite a few paintings which make one actually come to the conclusion that the eye shows things differently to certain human beings than the way they really are, that is, that there really are men who see the present population of our nation only as rotten cretins; who, on principle, see meadows blue, skies green, clouds sulphur yellow, and so on—or, as they say, experience them as such. I do not want to enter into an argument here about the question of whether the persons concerned really do or do not see or feel in such a way, but in the name of the German people, I want to forbid these pitiful misfortunates who quite obviously suffer from an eye disease, to try vehemently to foist these products of their misinterpretation upon the age we live in, or even to wish to present them as “Art.”   ~Adolph Hitler, 1937
