Abstract
At the end of Being and Nothingness, Sartre defines the spirit of seriousness in the following way: “The spirit of seriousness has two characteristics: it considers values as transcendent givens independent of human subjectivity, and it transfers the quality of ‘desirable’ from the ontological structure of things to their simple material constitution.” My aim in this paper is to show how Sartre is susceptible to a tu quoque in terms of how he describes the threataspect of the world of objects. That is, in works such as Nausea, Sartre appears to regard the world of objects as inherently threatening, and thus he has transferred the quality of threatening from the ontological structure of things to their simple material constitution
