, both great thinkers, the one more of a moralist, and the other more of a metaphysician. When and how, if they were ever more akin than they came to be; their divergence took place, are difficult questions on which it may be well to make some remarks after we have tried to set forth the most important principles of Taoism.

Those principles have to be learned from the treatise of Laozi and the writings of Chuang-tzŭ . We can hardly say that the Taoism taught in them is the Taoism now current in China, or that has been current in it for many centuries; but in an inquiry into the nature and origin of religions these are the authorities that must be consulted for Taoism, and whose evidence must be accepted. The treatise, Actions and the Responses to Them , will show one of the phases of it at a much later period.
