I have always said that, with any sculpture, you have to be able to say, 'although this is not a ready-made, it could be one'. That's what a sculpture has to look like. It must have a certain relation to reality. I mean, not airy-fairy, let alone fabricated, so aloof and polite... And I don't see this aspect in many artists' work. Often, my feeling is that they think something up that is supposed to be art. That's not what I want at all. Rather, a sculpture is really a photo – although it can be shifted, it must still always have an aspect that reality has too.
