Art is not a substitute religion: it is a religion (in the true sense of the word: 'binding back', 'binding' to the unknowable, transcending reason, transcendent being). But the church is no longer adequate as a means of affording experience of the transcendental, and of making religion real - and so art has been transformed from a means into the sole provider of religion: which means religion itself.

The photograph is the only picture that can truly convey information, even if it is technically faulty and the object can barely be identified. A painting of a murder is of no interest whatever; but a photograph of a murder fascinates everyone.

When I look back on the townscapes now, they do seem to me to recall certain images of the destruction of Dresden during the war.

If, while I'm painting, I distort or destroy a motif, it is not a planned or conscious act, but rather it has a different justification: I see the motif, the way I painted it, is somehow ugly or unbearable. Then I try to follow my feelings and make it attractive. And that means a process of painting, changing or destroying - for however long it takes - until I think it has improved. And I don't demand an explanation from myself as to why this is so.

Turning to the colour-classification methodology: The starting point are the four pure colours red, yellow, green and blue; their in-between shades and scales of brightness result in colour schemes containing 16, 64, 256 and 1,024 shades. More colours would be pointless because it wouldn't be possible to distinguish between them clearly.

I originally came from Dresden, where Socialist Realism prevailed. Konrad Lueg and I came up with it, for the most part ironically, since I now live in capitalism. It was certainly 'realism', but in another form - the capitalist form, as it were. It wasn't meant that seriously. It was more a slogan for that particular Happening at a furniture store.

In 1981, I think, for the Kunsthalle in Düsseldorf. Before that I designed a mirror room for Kasper König's Westkunst show, but it was never built. All that exists is the design - four mirrors for one room.
