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").
Philosophy of religion
World Religions put forth various theories which affirm life after death and different kinds of postmortem existence. This is often tied to belief in an immortal individual soul or self (Sanskrit: atman) separate from the body which survives death, as defended by Plato, Descartes, Monotheistic religions like Christianity and many Indian philosophers. This view is also a position on the mind body problem, mainly, dualism. This view then must show not only that dualism is true and that souls exist, but also that souls survive death. As Kant famously argued, the mere existence of a soul does not prove its immortality, for one could conceive that a soul, even if it is totally simple, could still fade away or lose its intensity. H.H. Price is one modern philosopher who has speculated at length about what it would be like to be a disembodied soul after death.
