Sartre saw philosophy as lacking a genuinely atheist system and aimed to supply it.

Evidence

In one of his transcribed conversations with Beauvoir, he said to her, ‘It seems to me that a great atheist, truly atheist philosophy was something philosophy lacked. And that it was in this direction that one should now endeavour to work.’ Beauvoir replied, ‘To put it briefly, you wanted to make a philosophy of man.’ — Sarah Bakewell, At the Existentialist Café, 1018
