Despite the atheism which was axiomatic for his approach to philosophy and life itself, in an interview with Simone de Beauvoir from 1974, Sartre made the following curious remark:
I do not feel that I am the product of chance, a speck of dust in the universe, but someone who was expected, prepared, prefigured. In short, a being whom only a Creator could put here: and this idea of a creating hand refers to God.
Then again, as a student of mine once said to me during a class I was teaching on Hegel, people say all sorts of things when they are drunk.
