This article intends to show how, on the basis of the notion of "communicating neighborhood" established by Franklin Leopoldo e Silva, we may understand the main themes of Sartre's philosophy and the relations between them, e.g., the relations between metaphysics and history, subject and object, absolute and concrete (freedom), and aesthetic and ethics. By extending an expression initially established for the relation between philosophy and literature in Sartre, we intend to show that the notions of ambiguity and tension are essential as a key to all of Sartre's thought.
