"The learning of the gentleman enters through his ears, fastens to his heart, spreads through his four limbs, and manifests itself in his actions. ... The learning of the petty person enters through his ears and passes out his mouth. From mouth to ears is only four inches—how could it be enough to improve a whole body much larger than that?"

“A questioner asks: If human nature is evil, then where do ritual and rightness come from? I reply: ritual and rightness are always created by the conscious activity of the sages.”

“Learning proceeds until death and only then does it stop. ... Its purpose cannot be given up for even a moment. To pursue it is to be human, to give it up to be a beast.”

“The gentleman knows that whatever is imperfect and unrefined does not deserve praise. ... He makes his eyes not want to see what is not right, makes his ears not want to hear what is not right, makes his mouth not want to speak what is not right, and makes his heart not want to deliberate over what is not right. ... For this reason, power and profit cannot sway him, the masses cannot shift him, and nothing in the world can shake him.”

“In order to properly understand the big picture, everyone should fear becoming mentally clouded and obsessed with one small section of truth.”

“If an action ... involves little profit but much righteousness, do it.”

“One whose intentions and thoughts are cultivated will disregard wealth and nobility. One whose greatest concern is for the Way and righteousness will take lightly kings and dukes. It is simply that when one examines oneself on the inside, external goods carry little weight. A saying goes, "The gentleman makes things his servants. The petty man is servant to things.”
