辩德

原文

知人者智，自知者明。胜人者有力，自胜者强。知足者富。强行者有志。不失其所者久。死而不亡者寿。

王弼注

知人者智，自知者明。知人者，智而已矣，未若自知者超智之上也。胜人者有力，自胜者强。胜人者，有力而已矣，未若自胜者无物以损其力，用其智于人，未若用其智于己也。用其力于人，未若用其力于己也。明用于己，则物无避焉，力用于己，则物无改焉。知足者富。知足自不失，故富也。强行者有志。勤能行之，其志必获，故曰强行者有志矣。不失其所者久。以明自察，量力而行，不失其所，必获久长矣。死而不亡者寿。虽死而以为生之道，不亡乃得全其寿，身没而道犹存，况身存而道不卒乎。

英文 · James Legge

(Discriminating between attributes) He who knows other men is discerning; he who knows himself is intelligent. He who overcomes others is strong; he who overcomes himself is mighty. He who is satisfied with his lot is rich; he who goes on acting with energy has a (firm) will. He who does not fail in the requirements of his position, continues long; he who dies and yet does not perish, has longevity.
