Abstract: From Freud's works published now,we can see that his understanding of Mose mainly includes two aspects:one is to analyze from aesthetics and arts,the other is to analyze from religious science,religious history,ethics and psychology.For the former,he made a thorough analysis of Mose mainly based on the statue of Mos;for the latter,he mainly investigated a series of issues such as the source,birth and the background of growth-up of Mose's name,Mose and the foundation of Judaism.Through his analysis of the two aspects,he realized his purpose of criticizing religion by analyzing Mose,moreover,his study of Mose does not only include his critic about Judaism,but also include his critic about Christianity and other religions.And the main purpose of his critic is to pay attention to human and the fate of human.
