马克思的功绩在于他忽然在社会思想史上产生了一个质的变化。他解释历史，理解其动力，预测未来，但除了预测之外，他还表达了一个革命性的概念：世界不仅必须被解释，还必须被改变。
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.
