The virtue of a superior man is like the wind; the virtue of an inferior man is like grass. When the wind blows over the grass, it is sure to bend.
To know what one knows, and to know what one does not know, is true knowledge. Some may speak on matters they do not know, but I do not do so. One should listen much and choose the good to follow; observe much and retain it in memory. I cannot claim to be a sage, but I can practice without being wearied, and teach without being tired. In learning, one should feel as if one were not catching up, and fear losing what one has gained.
One should be quick in learning and not ashamed to ask questions of those of lower rank.
One with ability should ask those without ability; one with much knowledge should ask those with little. Possessing, one should act as if possessing nothing; being full, one should act as if empty. Even if offended, one should not retaliate. One is inspired by the Odes, established by Ritual, and perfected by Music. One should aim at the Way, stand on Virtue, rely on Benevolence, and roam among the Arts. Do not open the gate until the student is eager; do not make clear the point until the student is on the verge of expressing it.
If, when I lift one corner, the student cannot infer the other three, I do not repeat myself.
He who knows it is not equal to he who loves it; he who loves it is not equal to he who delights in it. I once went a whole day without eating and a whole night without sleeping, pondering, but found it useless; it is better to learn. To learn without thinking is misleading; to think without learning is perilous. If all hate him, one must examine the case; if all love him, one must also examine the case.
