Dualism (Indian philosophy)
Another form of dualism in Hindu philosophy is found in the Dvaita ("dualism") Vedanta school, which regards God and the world as two realities with distinct essences; this is a form of theistic dualism. By contrast, schools such as Advaita ("nondualism") Vedanta embrace absolute monism and regard dualism as an illusion ("maya").
Atheistic existentialism
Albert Camus writes of dualisms—between happiness and sadness—as well as life and death. In "The Myth of Sisyphus", such dualism becomes paradoxical because humans greatly value their existence while at the same time being aware of their mortality. Camus believes it is human nature to have difficulty reconciling these paradoxes; and indeed, he believed humankind must accept what he called "the Absurd". On the other hand, Camus is not strictly an existential atheist because the acceptance of "the Absurd" implies neither the existence of God nor the nonexistence of God (compare agnosticism).
