Jean-Paul Sartre uses his play No Exit to explore many of the existentialist themes discussed in his philosophical treatise Being and Nothingness. Most prominently, No Exit focuses on the ideas of competitive subjectivity, the look and others, objectification, and bad faith. One of the characters in this play – Inez Serrano – comes close to having the perspective of an existentialist, maybe even that of Sartre himself. Her advice to her companions in hell resembles Sartre’s arguments Sartre in Being and Nothingness.
The character of Inez embodies the opinions and ideas of Jean-Paul Sartre.
