Condensed into a single phrase, the injunction of Lao Tzu to mankind is, Follow Nature. This Is a good practical equivalent for the Chinese expression, Get hold of Tao, although Tao does not exactly correspond to the word Nature, as Ordinarily used by us to denote the sum of phenomena in this ever-changing universe. It seems to me, however, that the conception of Tao must have been reached, originally, through this channel. Lao Tzii, interpreting the plain facts of Nature before his eyes, concludes that behind her manifold workings there exists an ultimate Reality which in its essence is unfathom able and unknowable, yet manifests itself in laws of unfailing regularity. To this Essential Princi ple, this Power underlying the sensible phenomena of Nature, he gives, tentatively and with hesita tion, the name of Tao, the Way, though fully realising the inadequacy of any name to express the idea of that which is beyond all power of comprehension.
