There is sorrow, but I hope one can see that it is sorrow for the people who died so young and so crazy, for nothing. I have respect for them, but also for their wishes, or for the power of their wishes. Because they tried to change the stupid things in the world.

I have no motif, only motivation. I believe that motivation is the real thing, the natural thing, and that the motif is old-fashioned, even reactionary (as stupid as the question about the meaning of life)

It was not possible for us to produce the same optimism and the same kind of humour or irony. Actually, it was not irony. Lichtenstein is not ironic but he does have a special kind of humour. That's how I could describe it: humour and optimism. For Polke and me, everything was more fragmented. But how it was broken up is hard to describe.

Above all, it's never blind chance: it's a chance that is always planned, but also always surprising. And I need it in order to carry on, in order to eradicate my mistakes, to destroy what I've worked out wrong, to introduce something different and disruptive. I'm often astonished to find how much better chance is than I am.

I believe that you always have to believe. It's the only way; after all we both believe that we will do this exhibition. But I can't believe in God, as such, he's either too big or too small for me, and always incomprehensible, unbelievable.

I didn't actually know what the protesters in the West really wanted. It was fantastic here, so much freedom, and that was what they were calling musty, middle-class, and fascistic, a bleak period. Bleak was what the GDR was, and it alone had adopted, almost unchanged, Nazi Germany's methods of intimidation and ideas about propaganda and the use of force.

Theory has nothing to do with a work of art. Pictures which are interpretable, and which contain a meaning, are bad pictures. A picture presents itself as the Unmanageable, the Illogical, the Meaningless. It demonstrates the endless multiplicity of aspects; it takes away our certainty, because it deprives a thing of its meaning and its name. It shows us the thing in all the manifold significance and infinite variety that preclude the emergence of any single meaning and view.
