A work will be treated as art within a certain circle – that is, within the circle of let's say ten thousand people. There are about ten thousand in the world today who are prepared to take it on face value if you present anything to them as art, they deal with it straight on as art and tell you whether it stimulates them, moves them, or not. Some of them might even buy it... Anyway, it seems to me that within that ring of ten thousand, fortunately, that sincerity issue [the issue, is something art or not] is over. The reason why that issue failed is that it became obvious no one would live a life of art, a life of poverty, just to pull somebody's legs. In other words, there were compensating sacrifices for what people did.
