第三十三章
辩德
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

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.
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。
