未经审视的生活不值得过。

The merit of Marx is that he suddenly produces a qualitative change in the history of social thought. He interprets history, understands its dynamic, predicts the future, but in addition to predicting it, he expresses a revolutionary concept: the world must not only be interpreted, it must be transformed.

释义：跟交情浅的朋友说过深的话题，是愚蠢的；生活贫困的人总是希望得到富贵者的施舍，是糊涂的；没有取得他人的信任就进献忠言，会被误解为批评。
