| The existence of the thinking, different age has different interpretation of the philosopher. Marx and Sartre live in different historical stages of capitalism, about the existence of the meanings are also different. Marx holds that a man’s existence is social and Sartre think people exist is a subjective consciousness. In the research method, Marx stood in the social and historical development point of view, in the previous critical inheritance, and on the basis of dialectical, abstract and empirical combination of the study of human nature of existence, and the practice in that the people and the social development in an important role. Sartre, the use of the phenomenological research methods, through the phenomenological reductive way back to thing itself, the replacement and Sartre the core of human dialectics, through the intentionality method, and it is the existence of the study will be the subjectivity of the people as the starting point, in the study through the intuitionist method, as the subjectivity of the principle will Sartre’s person’s existence intentionality method further development, will eventually object unity and subjective consciousness.Marx and Sartre all live in capitalist society, Just live in capitalist society two different stage. Because about man’s existence the starting point of the different, resulting in about the existence of the core concepts such as people, alienation of the human’s practice, the freedom of the individual and the definition of the different also. So, although Marx and Sartre focused on the people, and made, but in about man’s existence issue with essence of but don’t, so, Sartre’s existentialism can’t fill Marx’s "study of person’s lack". |
