原文
曾子曰：“吾日三省吾身。为人谋，而不忠乎？与朋友交，而不信乎？传，不习乎？”
英译
Tseng Tzu said, "I review my behavior several times a day to discover whether it happened that I served somebody, yet I disobeyed the loyalty; or I affiliated with some friends, yet I violated the honesty; or I tried to instruct some pupils in something, yet I was not learned about it."
