““Once upon a time, Zhuang Zhou dreamed he was a butterfly, a butterfly flitting about happily, enjoying himself. He did not know that he was Zhou. Suddenly he awoke, and was palpably Zhou. He did not know whether he was Zhou, who had dreamed of being a butterfly, or a butterfly dreaming that he was Zhou. Now, there must be a difference between Zhou and the butterfly. This is called the transformation of things.””
