Humanbeing and concreteness in Gabriel Marcel

In this work we investigated the place and importance of man in the philosophy of Gabriel Marcel, and in this context, what the concept of concreteness means. The developments in science and technology together with the modern era on the one hand seem to undertake a role that facilitates human life; on the other hand, it brings the danger of decentralising the human being. In other words, people seem to be the subject but in reality they become to be an object. As a member of the existential thinkers who are aware of this danger, Marcel discusses this tragic existence of man in the context in his specific philosophical terminology and tries to make it meaningful in his harmony. According to Marcel human being has forgotten to question his being and he has become alienated to himself. Among the events of the ages, man has been captivated by his possesions and is stuck on them with an uncontrolled desire. Marcel set out on the basis of man's life practice and puts the concreteness of existence against all kinds of abstraction and conceptual content, abstaining from the traditional sense of life and experience since he puts a new meaning to them. All these concepts realization inevitably needs an intersubjects relationship. And the concreteness concept of Marcel shows us on which basis this intersubjects relationships should be built.
