smell [1].' How are we to attain this state? Here the Chinese moralist fails us. According to Chu Hsi's arrangement of the Treatise, there is only one sentence from which we can frame a reply to the above question. 'Therefore,' it is said, 'the superior man must be watchful over himself when he is alone [2].' Following. Chu's sixth chapter of commentary, and forming, we may say, part of it, we have in the old arrangement of the Great Learning all the passages which he has distributed so as to form the previous five chapters. But even from the examination of them, we do not obtain the information which we desire on this momentous inquiry. 8. Indeed, the more I study the Work, the more satisfied I become, that from the conclusion of what is now called the chapter of classical text to the sixth chapter of commentary, we have only a few fragments, which it is of no use trying to arrange, so as fairly to exhibit the plan of the author. According to his method, the chapter on the connexion between making the thoughts sincere and so rectifying the mental nature, should be preceded by one on the completion of knowledge as the means of making the thoughts sincere, and that again by one on the completion of knowledge by the investigation of things, or whatever else the phrase ko wu may mean. I am less concerned for the loss and injury which this part of the Work has suffered, because the subject of the connexion between intelligence and virtue is very fully exhibited in the Doctrine of the Mean, and will come under our notice in the review of that Treatise. The manner in which Chu Hsi has endeavoured to supply the blank about the perfecting of knowledge by the investigation of things is too extravagant. 'The Learning for Adults,' he says, 'at the outset of its lessons, instructs the learner, in regard to all things in the world, to proceed from what knowledge he has of their principles, and pursue his investigation of them, till he reaches the extreme point. After exerting himself for a long time, he will suddenly find himself possessed of a wide and far-reaching penetration. Then, the qualities of all things, whether external or internal, the subtle or the coarse, will be apprehended, and the mind, in its entire substance and its relations to things, will be perfectly intelligent. This is called the investigation of things. This is called the perfection of knowledge [3].' And knowledge must be thus perfected before we can achieve the sincerity of our thoughts, and the rectifying of our hearts! 1 Comm. vi. 1. 2 Comm. vi. 2. 3 Suppl. to Comm. Ch. v.
