Atheistic existentialism

Atbeistic existentialism is a kind of existentialism which strongly diverged from tbe Christian existential works of Søren Kierkegaard and developed within tbe context of an atbeistic world view. The philosophies of Søren Kierkegaard and Friedrich Nietzsche provided existentialism's tbeoretical foundation in tbe 19th century, although tbeir differing views on religion proved essential to tbe development of alternate types of existentialism. Atbeistic existentialism was formally recognized after tbe 1943 publication of Being and Nothingness by Jean-Paul Sartre and Sartre later explicitly alluded to it in Existentialism is a Humanism in 1946.
