I used to think of that line in Allen Ginsberg's 'Howl', about the 'sad cup of coffee'.. ..I have had cold coffee and hot coffee and lousy coffee, But I've never had a sad cup of coffee.

People ask me, 'Don't you ever run out of ideas?' In the first place I don't use ideas. Every time I have an idea it's too limiting, and usually turns out to be a disappointment. But I haven't run out of curiosity.

An empty canvas is full only if you want it to be full.

I don't like masterpieces having one-night stands in collectors' homes between auctions.

For the first time, I wasn't embarrassed by the look of beauty, of elegance, because when you see someone who has only one rag as their property, but it happens to be beautiful and pink and silk, beauty doesn't have to be separated... I have always said that you shouldn't have biases, you shouldn't have prejudices. But before that [before his trip to India, circa 1975] I'd never been able to use purple, because it was too beautiful.

There was something about the self-confession and self-confusion of Abstract expressionism - as though the man and the work were the same - that personally always put me off because at that time my focus was in the opposite direction.
