1. The Doctrine of the Mean is a work not easy to understand. 'It first,' says the philosopher Chang, 'speaks of one principle; it next spreads this out and embraces all things; finally, it returns and gathers them up under the one principle. Unroll it and it fills the universe; roll it up, and it retires and lies hid in secrecy [2].' There is this advantage, however, to the student of it, that more than most other Chinese Treatises it has a beginning, a middle, and an end. The first chapter stands to all that follows in the character of a text, containing several propositions of which we have the expansion or development. If that development were satisfactory, we should be able to bring our own minds en rapport with that of the author. Unfortunately it is not so. As a writer he belongs to the intuitional school more than to the logical. This is well put in the 'Continuation of the General Examination of Literary Monuments and Learned Men,'-- 'The philosopher Tsang reached his conclusions by following in the train of things, watch- 1 See the 四書拓餘說, art. 中庸. 2 See the Introductory note of Chu Hsi. ing and examining; whereas Tsze-sze proceeds directly and reaches to Heavenly virtue. His was a mysterious power of discernment, approaching to that of Yen Hui [1].' We must take the Book and the author, however, as we have them, and get to their meaning, if we can, by assiduous examination and reflection. 2. 'Man has received his nature from Heaven. Conduct in accordance with that nature constitutes what is right and true,-- is a pursuing of the proper Path. The cultivation or regulation of that path is what is called Instruction.' It is with these axioms that the Treatise commences, and from such an introduction we might expect that the writer would go on to unfold the various principles of duty, derived from an analysis of man's moral constitution. Confining himself, however, to the second axiom, he proceeds to say that 'the path may not for an instant be left, and that the superior man is cautious and careful in reference to what he does not see, and fearful and apprehensive in reference to what he does not hear. There is nothing more visible than what is secret, and nothing more manifest than what is minute, and therefore the superior man is watchful over his aloneness.' This is not all very plain. Comparing it with the sixth chapter of Commentary in the Great Learning, it seems to inculcate what is there called 'making the thoughts sincere.' The passage contains an admonition about equivalent to that of Solomon,-- 'Keep thy heart with all diligence, for out of it are the issues of life.' The next paragraph seems to speak of the nature and the path under other names. 'While there are no movements of pleasure, anger, sorrow, or joy, we have what may be called the state of equilibrium. When those feelings have been moved, and they all act in the due degree, we have what may be called the state of harmony.
