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.
[6][7] 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.
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.
Dualism was first seen implicitly in Egyptian religious beliefs by the contrast of the gods Set (disorder, death) and Osiris (order, life).
One well-known example of a bitheistic or duotheistic theology based on gender polarity is found in the neopagan religion of Wicca.
However, there is also a ditheistic theme within traditional Wicca, as the Horned God has dual aspects of bright and dark - relating to day/night, summer/winter - expressed as the Oak King and the Holly King, who in Wiccan myth and ritual are said to engage in battle twice a year for the hand of the Goddess, resulting in the changing seasons.
(Within Wicca, bright and dark do not correspond to notions of "good" and "evil" but are aspects of the natural world, much like yin and yang in Taoism.)
However, bitheistic and ditheistic principles are not always so easily contrastable, for instance in a system where one god is the representative of summer and drought and the other of winter and rain/fertility (cf.
Marcionism, an early Christian sect, held that the Old and New Testaments were the work of two opposing gods: both were First Principles, but of different religions.
[12][1] Zoroastrianism or "Mazdayasna" is one of the world's oldest continuously-practiced religions, based on the teachings of the Iranian-speaking prophet Zoroaster.
Christian dualism refers to the belief that God and creation are distinct, but interrelated through an indivisible bond.
[1] However, Gnosticism is a diverse, syncretistic religious movement consisting of various belief systems generally united in a belief in a distinction between a supreme, transcendent God and a blind, evil demiurge responsible for creating the material universe, thereby trapping the divine spark within matter.
[25] The problem of evil is difficult to reconcile with absolute monism, and has prompted some Christian sects to veer towards dualism.
This tradition of Christian dualism, founded by Constantine-Silvanus, argued that the universe was created through evil and separate from a moral God.
In any case, the Roman Catholic Church denounced the Cathars as heretics, and sought to crush the movement in the 13th century.
[27] The Dvaita Vedanta school of Indian philosophy espouses a dualism between God and the universe by theorizing the existence of two separate realities.
The distinguishing factor of this philosophy as opposed to Advaita Vedanta (monistic conclusion of Vedas) is that God takes on a personal role and is seen as a real eternal entity that governs and controls the universe.
[29] Alternatively, dualism can mean the tendency of humans to perceive and understand the world as being divided into two overarching categories.
This form of ontological dualism exists in Taoism and Confucianism and a foundational theory within Traditional Chinese medicine, beliefs that divide the universe into the complementary oppositions of yin and yang.
[30] In traditions such as classical Hinduism (Samkhya, Yoga, Vaisheshika and the later Vedanta schools, which accepted the theory of Gunas), Chinese Pure land and Zen Buddhism or Islamic Sufism, a key to enlightenment is "transcending" this sort of dualistic thinking, without merely substituting dualism with monism or pluralism.
[31] Some of the common associations with yang and yin, respectively, are: male and female, light and dark, active and passive, motion and stillness.
[31] The yin and yang symbol actually has very little to do with Western dualism; instead it represents the philosophy of balance, where two opposites co-exist in harmony and are able to transmute into each other.
[33] Among others, also dualistic myths were investigated in researches which tried to compare the mythologies of Siberian peoples and settle the problem of their origins.
[38] It must be admitted that, for Kets, neither dualistic organization of society[39] nor cosmological dualism[40] has been researched thoroughly: if such features existed at all, they have either weakened or remained largely undiscovered;[39] although there are some reports on division into two exogamous patrilinear moieties,[41] folklore on conflicts of mythological figures, and also on cooperation of two beings in creating the land:[40] the diving of the water fowl.
[42] If we include dualistic cosmologies meant in broad sense, not restricted to certain concrete motifs, then we find that they are much more widespread, they exist not only among some Siberian peoples, but there are examples in each inhabited continent.
