Sartre's Absent God

Sartre's memoir Words turns on his mid-life realisation that, although he had abandoned belief in God, he had hitherto based his work on a religious model. From this point God no longer appears as a primary reference in his writings. This is in sharp contrast with the pervasive presence of God in earlier works, especially in his ontology and related reflections on ethics. In ontology Sartre was particularly concerned with the Cartesian idea of the creator God as ens causa sui. Adapting this to his own system, he uses the idea of causa sui to mark the absolute (but non-substantial) existence of for-itself being (consciousness) as separate from the uncreated plenitude of in-itself being. He then argues that the idea of God as a consciousness that founds its own being is an impossible synthesis of the for-itself and the in-itself. The idea nonetheless remains fundamental for consciousness, for desire, which arises in response to lack, ultimately the lack of in-itself being, reflects an original choice that leads to constant striving towards the impossible goal of being God. This theme haunts the ontology from beginning to end. Sartre offers a system to rival Descartes or Leibniz, but adopts a quasi-religious framework of salvation in which, apart from the promise of a possible escape from ontological destiny, human beings are condemned to futility. In ethics he explores the idea of conversion from original choice to an authentic choice of freedom, but fails to break out of the closed framework set by the ontology.
