This article offers a reading of Jean-Paul Sartre’s phenomenology in light of Jean-Luc Marion’s more recent phenomenology. It may seem odd to compare Sartre to Marion, given that Sartre is well-known for his avowed atheism and his account of intentionality while Marion is primarily known for his work on religious phenomena and counter-intentionality. However, this article shows that there are many ways in which Sartre anticipates Marion’s work on phenomenological reduction and excessive phenomenality. By reading Sartre’s phenomenology in light of (...) Marion’s, and particularly Sartre’s analysis of the viscous slime in Being and Nothingness in relation to Marion’s account of ‘saturated phenomena’, this article presents a fresh interpretation of Sartre as a phenomenologist who has invaluable insights not only on the structures of consciousness and phenomenality, but also for the contemporary theoretical interest in the relationship between human and nonhuman entities.
