心理学是科学，教学是艺术；科学永远不会直接从自身产生艺术。
Psychology is a science, and teaching is an art; and sciences never generate arts directly out of themselves.
我相信，我能将世界上所有的艺术和科学统一为一个伟大的整体的日子不会太远。
The documenta must always be a risk, never a routine.
I never try to predict the market; I just try to be prepared for whatever it does.
I think it's important to take risks in life. If you don't take risks, you'll never grow.
作家必须是一个永远的外来者，一个所有权力的批评者。
The final purpose of art is to intensify, even, if necessary, to exacerbate, the moral consciousness of people.
