Critique of Dialectical Reason: Critique of Dialectical Reason (French: "Critique de la raison dialectique" ) is a 1960 book by the philosopher Jean-Paul Sartre, in which the author further develops the existentialist Marxism he first expounded in his essay "Search for a Method" (1957).  "Critique of Dialectical Reason" and "Search for a Method" were written as a common manuscript, with Sartre intending the former to logically precede the latter.  Sartre's second large-scale philosophical treatise, "Being and Nothingness" (1943) having been the first, "Critique of Dialectical Reason" has been seen by some as an abandonment of Sartre's original existentialism, while others have seen it as a continuation and elaboration of his earlier work.  It was translated into English by Alan Sheridan-Smith.

Saint Genet: Saint Genet, Actor and Martyr (French: "Saint Genet, comédien et martyr" ) is a book by the French philosopher Jean-Paul Sartre about the writer Jean Genet especially on his "The Thief's Journal".  It was first published in 1952.  Sartre described it as an attempt "to prove that genius is not a gift but the way out that one invents in desperate cases."  Sartre also based his character Goetz in his play "The Devil and the Good Lord" (1951) on his analysis of Genet's psychology and morality.  Sartre has been credited by David M. Halperin with providing, "a brilliant, subtle, and thoroughgoing study of the unique subjectivity and gender positioning of gay men".

The Transcendence of the Ego: The Transcendence of the Ego (French: "La Transcendance de l'ego: Esquisse d'une description phénomenologique" ) is a philosophical and psychological essay written by Jean-Paul Sartre in 1934 and published in 1936.  The essay demonstrates Sartre’s transition from traditional phenomenological thinking and most notably his break from Edmund Husserl’s school of thought (phenomenology), and into his own.  This transition is more apparent after Sartre’s military service from 1939 where we observe a rather more sympathetic view of being in the world, a topic that is dealt with in much greater detail in his 1943 work "Being and Nothingness".  This essay begins Sartre's study and hybridisation of phenomenology and ontology.
