This paper takes the movement of transcendence in Sartre and examines it in relation to another understanding of transcendence in relation to God circulating in Paris in Sartre’s formative years: that of Karl Jaspers. Through exploring the transmission and reception of Jaspers' thought in French philosophy, different understandings can be advanced as to why he engages with the figure of God as that which we transcend towards, however impossibly, and why he counts Jaspers as a Catholic existentialist.
