This essay addresses ‘the God‐haunted Atheist paradox’ in Sartre's early philosophy and argues against a series of efforts to show that Sartre maintains a ‘secular theology’. It shows that if Sartre's ontology is correct, the God of ‘classic theism’ cannot possibly exist. It argues against two sophisticated efforts to show that theological influences infiltrate Sartre's early ontology and permeate his moral psychology. It also rejects the claim that Sartre's (Existentialism is a Humanism, 1946/2007, Yale University Press) distinction between secular and (...) religious existentialism ‘has no basis in fact’. It shows that Sartre appropriates religious language in order to give debunking secular explanations for religious phenomena and that he inverts traditional Christian values. It concludes that Sartre is an anti‐theologian. (shrink)
