下述评论的某些部分曾以不同形式包含在我不久前给几所大学、学院和研究生班作的演讲之中。一位著名诗人兼版画艺术评论家曾是我某次演讲的听众。后来,这位评论家对我说:“你们毁了我们,彻底毁了我们的事业,你们使我的朋友和我都变成了过时的废物。”我说,我既不相信果真如此,也完全没有这种意图。 Some parts of the comments below were in various forms included in my recent lectures given to several universities, colleges and graduate classes. A famous poet and print art critic was once my listener for a speech. Later, the critic said to me: “You have ruined us and completely ruined our cause, and you have turned my friends and I into outdated wastes.” I said I did not believe it or not There is no such intention.
