Zhuang Zhou Dreams of a Butterfly
Zhuangzi records that he once dreamed he had become a butterfly, fluttering and dancing, wholly forgetting he was Zhuang Zhou; on waking he was plainly Zhuang Zhou again, and did not know whether Zhuang Zhou had dreamed the butterfly, or the butterfly had dreamed Zhuang Zhou. This parable explores the relativity of the boundary between reality and illusion, self and things, one of the most widely told epistemological images in the history of Chinese philosophy.
"You Are Not a Fish; How Do You Know the Joy of Fish?"
Zhuangzi and his friend Huizi were strolling on a bridge over the Hao River, and Zhuangzi, seeing the fish swimming freely in the water, sighed that "the fish are happy." Huizi challenged, "You are not a fish; how do you know the joy of fish?" Zhuangzi retorted, "You are not I; how do you know that I do not know the joy of fish?" This famous "debate on the Hao" explores the epistemological difficulty of "whether one can truly know another’s inner experience," and is still a classic case in the teaching of Chinese philosophy for discussing the problem of "intersubjectivity."
