For example, in England, we teach about Expressionism, but it is not the same in England as it is in Germany, because Expressionism is more important in the history of German art. So although it is the same history, the emphasis is different.

It is very important to develop the thing that you are naturally good at, that you are truly interested in.

There is a complete difference between art and the art market. Prices are high now for the simple reason that there are people are willing to pay them. The market dominates the art world today because at the moment collectors call the shots. Like everything else that won't last forever.

I thought the objects we value least because they were ubiquitous were actually the most extraordinary.

I think that the exchange is very important. Before I did the exhibition in Shanghai, I was a judge for the John Moores Painting Prize and that was very interesting for me, because some of the judges are Chinese and some are British, and we look at the work together. It was fascinating that most of the time we were in complete agreement, but some of the time we were not. People send their works from all over China. For a foreigner, this gave me a very good picture about what is happening in China and its art today.

When I started teaching in the late 60s, in a time of student revolutions and changes, they changed in question of society and authority.

[I] don't want people to see it [paintings] as a specific intention on my part. If somebody has that interest in these objects, of course they can see that, but from my own point of view, I'd rather stay as neutral as possible.
