rather of convergent origin. They are related to a dualistic organization of society (moieties); in some cultures, the social organization may have ceased to exist, but mythology preserves the memory in more and more disguised ways. Moral dualism Moral dualism is the belief of the great complement or conflict between the benevolent and the malevolent. Like ditheism/bitheism (see below), moral dualism does not imply the absence of monist or monotheistic principles. Moral dualism simply implies that there are two moral opposites at work, independent of any interpretation of what might be "moral" and—unlike ditheism/bitheism—independent of how these may be represented. For example, Mazdaism (Mazdean Zoroastrianism) is both dualistic and monotheistic (but not monist by definition) since in that philosophy God—the Creator—is purely good, and the antithesis—which is also uncreated–is an absolute one. Mandaeism is monotheistic and Gnostic and in its cosmology, the World of Light () that is good, is contrasted with the World of Darkness or underworld (alma d-hšuka) that is evil. Zurvanism (Zurvanite Zoroastrianism) and Manichaeism are representative of dualistic and monist philosophies since each has a supreme and transcendental First Principle from which the two equal-but-opposite entities then emanate. This is also true for the lesser-known Christian gnostic religions, such as Bogomils, Catharism, and so on. More complex forms of monist dualism also exist, for instance in Hermeticism, where Nous "thought"—that is described to have created man—brings forth both good and evil, dependent on interpretation, whether it receives prompting from the God or from the Demon. Duality with pluralism is considered a logical fallacy. History Moral dualism began as a theological belief. Dualism was first seen implicitly in Egyptian religious beliefs by the contrast of the gods Set (disorder, death) and Osiris (order, life). The first explicit conception of dualism came from the Ancient Persian religion of Zoroastrianism around the mid-fifth century BC. Zoroastrianism is a monotheistic religion that believes that Ahura Mazda is the eternal creator of all good things. Any violations of Ahura Mazda's order arise from druj, which is everything uncreated. From this comes a significant choice for humans to make. Either they fully participate in human life for Ahura Mazda or they do not and give druj power. Personal dualism is even more distinct in the beliefs of later religions. The religious dualism of Christianity between good and evil is not a perfect dualism as God (good) will inevitably destroy Satan (evil). Early
