《孟子·公孙丑上》2A.6:孺子将入于井与四端

孟子用“孺子将入于井”证明同情不是表演出来的社会姿态,而是人人本有的四端开端,也是仁政的心理根据。这章也适合放回四端、性善与王道根据这一问题链中理解。

孟子曰:「人皆有不忍人之心。先王有不忍人之心,斯有不忍人之政矣。以不忍人之心,行不忍人之政,治天下可运之掌上。所以谓人皆有不忍人之心者,今人乍见孺子将入于井,皆有怵惕恻隐之心;非所以内交于孺子之父母也,非所以要誉于乡党朋友也,非恶其声而然也。由是观之,无恻隐之心,非人也。无羞恶之心,非人也。无辞让之心,非人也。无是非之心,非人也。恻隐之心,仁之端也;羞恶之心,义之端也;辞让之心,礼之端也;是非之心,智之端也。人之有是四端也,犹其有四体也。有是四端而自谓不能者,自贼者也;谓其君不能者,贼其君者也。凡有四端于我者,知皆扩而充之矣,若火之始然,泉之始达。茍能充之,足以保四海;茍不充之,不足以事父母。」

英文参考译文

Mencius said, 'All men have a mind which cannot bear to see the sufferings of others. 'The ancient kings had this commiserating mind, and they, as a matter of course, had likewise a commiserating government. When with a commiserating mind was practised a commiserating government, to rule the kingdom was as easy a matter as to make anything go round in the palm. When I say that all men have a mind which cannot bear to see the sufferings of others, my meaning may be illustrated thus: even now-a-days, if men suddenly see a child about to fall into a well, they will without exception experience a feeling of alarm and distress. They will feel so, not as a ground on which they may gain the favour of the child's parents, nor as a ground on which they may seek the praise of their neighbours and friends, nor from a dislike to the reputation of having been unmoved by such a thing. From this case we may perceive that the feeling of commiseration is essential to man, that the feeling of shame and dislike is essential to man, that the feeling of modesty and complaisance is essential to man, and that the feeling of approving and disapproving is essential to man. The feeling of commiseration is the principle of benevolence. The feeling of shame and dislike is the principle of righteousness. The feeling of modesty and complaisance is the principle of propriety. The feeling of approving and disapproving is the principle of knowledge. Men have these four principles just as they have their four limbs. When men, having these four principles, yet say of themselves that they cannot develop them, they play the thief with themselves, and he who says of his prince that he cannot develop them plays the thief with his prince. Since all men have these four principles in themselves, let them know to give them all their development and completion, and the issue will be like that of fire which has begun to burn, or that of a spring which has begun to find vent. Let them have their complete development, and they will suffice to love and protect all within the four seas. Let them be denied that development, and they will not suffice for a man to serve his parents with.'

核心问题

为什么孟子要用“孺子将入于井”的场景来论证人性?

因为这个瞬间能尽量排除利益、名声和关系计算。如果人仍会先起怵惕恻隐之心,就说明仁的开端先于外部奖惩存在。
