Abstract: The logic of humanism in Paris Manuscripts is the overall and macroscopic framework of Karl Marxs critique of the estranged labor while the logic of materialism is the specific microscopic framework of his critique of the labor to earn a living. Although Marxs concept of labor fulfills the governance of dual logic， the logic of humanism， which takes the core status， makes the critical labor theory hover between the inevitability and the actuality in embarrassment and has to declare the failure in theoretical purpose and evolution path of Paris Manuscripts. However， in any case， the basic characteristics of Marxs labor concept in “Paris Period” still carry important implications to the modernity process of Chinese society.

Key words: Karl Marx, Paris Manuscripts, labor, logic of humanism, logic of materialism
