I believe that the quintessential task of every painter in any time has been to concentrate on the essential.

The desire to please is maligned, unfairly. There are many sides to it. First of all, pictures have to arouse interest before people will even look at them, and then they have to show something that holds that interst - and naturally they have to be presentable, just as a song has to be sung well, otherwise people run away. One mustn't underrate this quality, and I have always been delighted when my pieces have also appealed to the museum guards, the laymen.

I'm never really sure what that word means, but however inaccurately I use it, 'classical' was always my ideal, as long as I can remember, and something of that has always stayed with me, to this day. Of course, there were difficulties, because in comparison to my ideal, I didn't even come close.

I see the bomber pictures as an anti-war statement... which they aren't - at all. Pictures like that don't do anything to combat war. They only show one tiny aspect of the subject of war - maybe only my own childish feelings of fear and fascination with war and with weapons of that kind.

Without form, communication stops... without form, you have everybody burbling on to themselves, whenever and however, things that no one else can understand and - rightly - no one else is interested in.

The paint for the grey paintings was mixed beforehand and then applied with different implements - sometimes a roller, sometimes a brush. It was only after painting them that I sometimes felt that the grey was not yet satisfactory and that another layer of paint was needed.

Almost every work of art is an analogy. When I make a representation of something, this too is an analogy to what exists; I make an effort to get a grip on the thing by depicting it. I prefer to steer clear of anything aesthetic, so as not to set obstacles in my own way and not to have the problem of people saying: 'Ah, yes, that's how he sees the world, that's his interpretation.'
