Philosophers just explain the world in diverse ways,while ignoring the problem of changing the world.Explaining the world is based on the matter of fact,while changing the world on a matter of value.Based on the scientific view of practice,starting from human sensibility and object activities,Marx inherited and transformed dialectics from Hegel,created the dialectic of labor in anthropology,truly unified factual and value judgment,realizing the convergence of facts and values.In the meanwhile,Marx also established the internal connection between science and ethics,and built a combination of"be"and"should".
