I wanted to say something different: the pictures are also a leave-taking, in several respects. Factually: these specific persons are dead; as a general statement, death is leave-taking. And then ideologically: a leave-taking from a specific doctrine of salvation and, beyond that, from the illusion that unacceptable circumstances of life can be changed by this conventional expedient of violent struggle.

Architecture was, or is, a kind of hobby, an inclination I have to fiddling around and building things. Putting up shelves or cupboards, or making tools, or designing houses ... it always has a functional or social motivation. If social changes are in the air, I am gripped immediately by the desire to build, and I think that I accelerate or anticipate changes in my life by doing so, at least in draft. In the case of my house, that was anticipation: in other words, first build, then change one's life.

But my motivation was more a matter of wanting to create order - to keep track of things. All those boxes full of photographs and sketches weigh you down, because they have something unfinished, incomplete, about them. So it's better to present the usable material in an orderly fashion and throw the other stuff away. That's how the Atlas came to be, and I exhibited it a few times.

To me, grey is the welcome and only possible equivalent for indifference, noncommitment, absence of opinion, absence of shape. But grey, like formlessness and the rest, can be real only as an idea, and so all I can do is create a colour nuance that means grey but is not it. The painting is then a mixture of grey as a fiction and grey as a visible, designated area of colour.

I do not mistrust reality, of which I know next to nothing, but I am suspicious regarding the image of reality which our senses convey to us, and which is incomplete and limited. Our eyes have developed such as to survive. It is merely coincidence that we can see stars with them, as well.

I believe that art has a kind of rightness, as in music, when we hear whether or not a note is false

I started doing 'figures', then, one day, all of a sudden, I started doing abstraction. And then I started doing both. But it was never really a conscious decision. It was simply a question of desire. In fact, I really prefer making figurative work, but the figure is difficult. So to work around the difficulty I take a break and paint abstractly. Which I really like, by the way, because it allows me to make beautiful paintings.
