Chapter 33, Part 2D - Chuang Tzu

The disciples of Hsiang-li Ch'in, the followers of Wu Hou, and the Mo-ists of the south such as K'u Huo, Chi Ch'ih, Teng Ling-tzu, and their like all recite the Mo-ist canon, and yet they quarrel and disagree in their interpretations, calling each other "Mo-ist factionalists."

In their discussions of "hard" and "white," "difference" and "sameness," they attack back and forth; in their disquisitions on the incompatibility of "odd" and "even" they exchange volleys of refutation. They regard the Grand Master of their sect as a sage, each sect trying to make its Grand Master the recognized head of the school in hopes that his authority will be acknowledged by later ages, but down to the present the dispute remains unresolved.

Mo Ti and Ch'in Ku-li were all right in their ideas but wrong in their practices, with the result that the Mo-ists of later ages have felt obliged to subject themselves to hardship "till there is no down left on their calves, no hair on their shins" - their only thought being to outdo one another. Such efforts represent the height of confusion, the lowest degree of order.

Nevertheless, Mo Tzu was one who had a true love for the world. He failed to achieve all he aimed for, yet, wasted and worn with exhaustion, he never ceased trying. He was indeed a gentleman of ability!
