The concept of freedom in Sartre's "Being and nothingness"

The main subject of Sartre's philosophy is the conception of freedom that appears in human existence and man's relationship with the world and it does not fell from favor at all. Therefore, it seems necessary to delibarete on the concept of freedom in such a thesis which is about Sartre. Accordingly, in this study, generally it will be tried to mention of his concept of freedom and the point of being on the basis of what are lying on his thought's foundation. In this context, firstly, it will be mentioned of some important figures and their philosophical thoughts which influenced Sartre's idea in the philosophy of history, then it will be discussed how Sartre commented on Being and connected with that it will be focused on the concept of "nothingness" which emerges in the direction of questioning the deep meaning of the relationship between man and the world of objects and it will be dealt what kind of relationship there is between the human actualization and the concomittants concepts like 'nausea' and 'throwness' and freedom. Finally I argue that, according to Sartre, freedom is the foundation of man and it means that understanding of human existence is to understand freedom coordinately. For Sartre argues that what we call freedom is not a human being added to or acquired / acquired; This freedom expresses that it is a freedom that emerges from human nothingness and is always connected to human existence.
