Jin Xin II · Passage 31 / 38 · 孟子 7B.31
Mencius 7B.31: extend what people already cannot bear
Benevolence and righteousness are not manufactured from nothing. They grow by extending limits and sensitivities that already exist in every person.
孟子曰:「人皆有所不忍,達之於其所忍,仁也;人皆有所不為,達之於其所為,義也。人能充『無欲害人』之心,而仁不可勝用也。人能充『無穿窬』之心,而義不可勝用也。人能充無受爾汝之實,無所往而不為義也。士未可以言而言,是以言餂之也;可以言而不言,是以不言餂之也。是皆穿逾之類也。」
Mencius said, 'All men have some things which they cannot bear; extend that feeling to what they can bear, and benevolence will be the result. All men have some things which they will not do; extend that feeling to the things which they do, and righteousness will be the result. If a man can give full development to the feeling which makes him shrink from injuring others, his benevolence will be more than can be called into practice. If he can give full development to the feeling which refuses to break through, or jump over, a wall, his righteousness will be more than can be called into practice. If he can give full development to the real feeling of dislike with which he receives the salutation, "Thou," "Thou," he will act righteously in all places and circumstances. When a scholar speaks what he ought not to speak, by guile of speech seeking to gain some end; and when he does not speak what he ought to speak, by guile of silence seeking to gain some end; both these cases are of a piece with breaking through a neighbour's wall.'

Central question
Why does Mencius say that benevolence and righteousness can be developed from what all people already cannot bear and will not do?
Direct answer
Because he thinks morality is not externally installed but internally extended. Everyone already has some lines they cannot cross; the question is whether those lines are expanded and stabilized.
First principle
Real moral growth does not create a new person from zero. It extends the boundaries and sensitivities that are already present in the heart.
Why it matters
This passage serves searches around extension of moral feeling, what one cannot bear, and Mencius on the inner beginnings of benevolence and righteousness.

Citation note
Do not mistake it for easy moral optimism. Mencius is not saying goodness will spread automatically, only that the starting point is already there and must be deliberately extended.
