1844 "Economics-Philosophy Manuscript" is an unfinished manuscript written by Marx in his youth to sum up his thoughts and clarify his thinking problems. It consists of three parts. This is a book about political economy and philosophy. But "alienated labor" and "* * * productism" contain rich and profound economic thoughts, so they occupy an extremely important position in the history of Marxist economics. Although the Manuscript still leaves traces of Feuerbach's humanism in the expression of some problems, it expounds the origin of economy and economics from the perspective of productive labor practice for the first time, which opens up a new road for the study of economics. In this sense, Manuscript is the glorious starting point of Marxist economics.
