Another group of existentialists, which includes Sartre and his groundbreaking German predecessor Martin Heidegger. Sartre argues that atheistic existentialism is defined by the belief that, for humans, “existence precedes essence.” While Sartre rejects the existence of God, at the end of his lecture he suggests that “even if God were to exist, it would make no difference.” Rather, atheist existentialists believe that humans are morally responsible for their actions and beliefs regardless of God’s existence and still need to “rediscover” themselves either way.
