 Sartre, too, is subject to Camus’s criticisms—and not just politically as will be described in the following section. Although some of the ideas in The Myth of Sisyphus drew on Sartre’s Nausea (as noted above), in 1942 Sartre was not yet regarded as an “existentialist”. But as Sartre’s philosophy developed, he went on to explore how human activity constitutes a meaningful world from the brute, meaningless existence unveiled in his  novel[2]  (Aronson 1980, 71–88). In the process, the absurdity of Nausea becomes the contingency of Being and Nothingness, the fact that humans and things are simply there with no explanation or reason. As Sartre described it, the absurd is “the universal contingency of being which is, but which is not the basis of its being; the absurd is the given, the unjustifiable, primordial quality of existence” (quoted in Sagi 2002, 57). Having rooted human existence in such contingency, Sartre goes on to describe other fundamental structures of existence, core human projects, and characteristic patterns of behavior, including freedom and bad faith, all of which arise on this basis. The original contingency leads to our desire to undo it, to the futile project to “found being,” in other words the “useless passion” of the project to become God.
