The Child at the Well
In one line Mencius held that human nature is good: anyone who sees a child about to fall into a well feels alarm.
Mencius was a Confucian thinker of the fourth century BCE. He argued that human nature is good. His best-known argument is a thought experiment: anyone who suddenly sees a small child about to fall into a well feels alarm and compassion. Not to win the parents’ favor or the praise of neighbors, but at once.
He called such responses sprouts. Compassion is the sprout of benevolence, shame of righteousness, deference of propriety, and the sense of right and wrong of wisdom. Sprouts are real but small. They have to be cultivated, or they wither.
His parable of Ox Mountain makes the point: the hill was once wooded, but axes and grazing left it bare, and people now think bareness is its nature. A person who does wrong has been stripped in the same way.
Go deeper
Mencius told King Xuan of Qi that a king who spared an ox from slaughter because he could not bear its frightened look already had the heart needed to rule well. The task was to extend that feeling to his people. Mencius also argued that a ruler who ruins his people loses the right to rule and may rightly be removed, a bold claim for his time.
The new volunteer
Tomas joins a food bank expecting to hand out boxes. He finds himself moved by an elderly man’s thanks, a feeling he had not expected.
He comes back the next week, and the next. The feeling grows into a habit of care that shapes how he treats people at work too. The sprout was there; practice grew it.
Try this today Notice one moment today when you felt for someone, and do one small thing to grow it.
