The war was a mirror; it reflected man's every virtue and every vice, and if you looked closely, like an artist at his drawings, it showed up both with unusual clarity.

In public buildings set aside for the care and maintenance of the goods of the middle ages, a staff of civil service art attendants praise all the dead, irrelevant scribblings and scrawlings that, at best, have only historical interest for idiots and layabouts.

The bourgeoisie and the petty bourgeoisie have armed themselves against the rising proletariat with, among other things, culture. It's an old ploy of the bourgeoisie. They keep a standing art to defend their collapsing culture.

In 1916, when Johnny Heartfield and I invented photomontage in my studio at the south end of the town at five o'clock one May morning, we had no idea of the immense possibilities, or of the thorny but successful career, that awaited the new invention. On a piece of cardboard we pasted a mishmash of advertisements for hernia belts, student song books and dog food, labels from schnaps and wine bottles, and photographs from picture papers, cut up at will in such a way as to say, in pictures, what would have been banned by the censors if we had said it in words.

Very little changed fundamentally, except that the proud German soldier had turned into a defeated bundle of misery and the great German army had disintegrated.

In 1916 I was discharged from military service, or rather, given a sort of leave of absence on the understanding that I might be recalled within a few months. And so I was a free man, at least for a while.

My drawings and paintings were done as an act of protest; I was trying by means of my work to convince the world that it is ugly, sick and hypocritical.
