Egotheism is deification of the self, or the view that the idea of God is nothing more than a conception of the self. The latter position presupposes the impossibility of divine revelation. As such, it is a denial of the validity of faith and most theistic traditions, except for deism.
Identification of the self with the divine, is a tenet of Hinduism (Atman as the "true self").
