That is, if we proceed from the concrete to the abstract. Given a large or a small thing, there is no limit to the smallness or greatness with which each may be respectively compared. The infinitesimal is a subdivision of the small; the colossal is an extension of the great. In this sense the two fall into different categories. "Both small and great things must equally possess form. The mind cannot picture to itself a thing without form, nor conceive a form of unlimited dimensions. The greatness of anything may be a topic of discussion, or the smallness of anything may be mentally realized. But that which can be neither a topic of discussion nor be realized mentally, can be neither great nor small. "Therefore, the truly great man, although he does not injure others, does not credit himself with charity and mercy. These are natural to him. He seeks not gain, but does not despise his followers who do. He struggles not for wealth, but does not take credit for letting it alone. He asks help from no man, but takes no credit for his self-reliance, neither does he despise those who seek preferment through friends. He acts differently from the vulgar crowd, but takes no credit for his exceptionality; nor because others act with the majority does he despise them as hypocrites. The ranks and emoluments of the world are to him no cause for joy; its punishments and shame no cause for disgrace. He knows that positive and negative cannot be distinguished, What is positive under certain conditions will be negative under others. These terms are in fact identical. See ch. ii. that great and small cannot be defined. They are infinite. "I have heard say, the man of TAO has no reputation; perfect virtue acquires nothing; the truly great man ignores self;--this is the height of self-discipline." Clause 2 of the above quotation appears with variations in ch. xxxviii of the _Tao-Te-Ching_. The variations settle the correctness of the rendering already given in _The Remains of Lao Tzŭ_, p. 26. "But how then," asked the Spirit of the River, "are the internal and external extremes of value and worthlessness, of greatness and smallness, to be determined?" With no standard of measurement. "From the point of view of TAO," replied the Spirit of the Ocean, "there are no such extremes of value or worthlessness. Men individually value themselves and hold others cheap. The world collectively withholds from the individual the right of appraising himself. "If we say that a thing is great or small because it is relatively great or small, then there is nothing in all creation which is not great, nothing which is not small. To know that the universe is but as a tare-seed, and that the tip of a hair is a mountain,--this is the expression of relativity.
