Atheist existentialism

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

Atheistic existentialism refers to the exclusion of any transcendental, metaphysical, or religious beliefs from philosophical existentialist thought (e.g. anguish or rebellion in light of human finitude and limitations). Nevertheless, it shares elements with religious existentialism (e.g. the Philosophy of Søren Kierkegaard) and with metaphysical existentialism (e.g. through phenomenology and the works of Heidegger). Atheistic existentialism confronts death anxiety without appealing to a hope of somehow being saved by a God, and often without any appeal to alternate forms of supernatural salvation such as reincarnation. For some thinkers, existential malaise is mostly theoretical (as it is with Sartre) while others are quite affected by existential anguish (e.g. Camus and his discussion of the Absurd and Nietzsche who articulated the will to power).
