In matters of conduct, the gentleman does not esteem feats that are difficult but improper. In matters of argument, he does not esteem improper inquiries. In matters of reputation, he does not esteem improper fame. Only what is proper does he esteem. To cast oneself into a river while clutching a heavy stone is a difficult thing to do, but Shentu Di could do it.¹ However, the gentleman does not esteem such conduct because it does not accord with ritual and yi.
Claims such as “Mountains and valley are level”, Heaven and Earth lie even”, “Qi and Qin are adjacent”, “It enters the ear and comes out the mouth”, “Women have whiskers”, “Eggs have feathers” — These are difficult arguments to propound, but Hui Shi and Deng Xi could do it. However, the gentleman does not esteem such arguments, because they do not accord with ritual and yi.

Robber Xhi was terrifying enough to make people stutter, but his reputation is widely known like the sun and moon and is ceaselessly handed down together with that of the Sages Shun and Yu.³ However, the gentleman does not esteem such reputation because it does not accord with ritual and yi. 

And so, I say: In matters of conduct, the gentleman does not esteem feats that are difficult but improper. In matters of argument, he does not esteem improper inquiries. In matters of reputation, he does not esteem improper fame. Only what is proper does he esteem. The Odes say; He does have many a good thing,/ But only with the right timing.
This expresses my meaning.
