``Chuang Tzu'' means ``Master Chuang''; his personal name was Chou, and he was a Taoist philosopher of the fourth century BC, contemporary with Plato and Aristotle. He was, according to the Records of the Historian, from a place called Meng, where he was ``an official in the lacquer garden.'' (No one is very sure what that means.) China at the time was fragmented into a number of incessantly-fighting kingdoms --- the era is known as the ``Warring States Period'' --- and it is thought that Meng was in the state of Sung. Chuang Chou is also recorded as being a member of the Chi-Hsia academy maintained by the larger and more advanced state of Ch'i, along with many of his most famous philosophical contemporaries, like Mencius and Hui Shih. Beyond this, we know exactly nothing about the life of Chuang Chou.
