excerpt fron "Chuang-tse" - Burton Watson translator

"The understanding of the men of ancient times went a long way. How far did it go? To the point where some of them believed that things have never existed - so far, to the end, where nothing can be added. Those at the next stage thought that things exist but recognized no boundaries among them. Those at the next stage thought there were boundaries but recognized no right and wrong. Because right and wrong appeared, the Way was injured, and because the Way was injured, love became complete."
