The term dualism has several uses:

Theological usage ("Western"/"theistic")
Main Article: Theology
In theology, dualism can refer to ditheism: the belief that there are two basic principles in the universe, usually personified as deities, that work in polar opposition to each other. For example, one god is good, the other evil; or one god works for order, the other for chaos. Both the Zoroastrian religion, three millennia old and still extant, and the essentially dead gnostic religion (and its variations such as, Manichaeism, Bogomils, Catharism, etc.) are dualistic, as is Mandaeanism. The third-century Christian heretic Marcion of Sinope held that the Old and New Testaments were the work of two opposing gods. The Christian conflict between God (the source of all good) and Satan (the source of all evil) is sometimes described in dualistic terms.
Theological usage ("Eastern"/"mystic")
Main Article: Mysticism
Alternatively, dualism can mean the tendency of humans to perceive and understand the world as being divided into just two categories. In this sense, it is dualistic when one perceives a tree as a thing separate from everything surrounding it, or when one perceives a "self" that is distinct from the rest of the world. In traditions such as Zen, a key to enlightenment is "overcoming" this sort of dualism, without merely substituting it with monism or pluralism.
In orthodox Indian philosophy, on the other hand, monism is explicitly affirmed by advaita vedanta, while it is rejected in favor of the dualism or pluralism of Dvaita; other schools, such as Vishishtadvaita and bhedabheda try to find routes in between.
The complementary aspects of masculinity and femininity are revered by certain Neo-pagan religions.
Usage in philosophy of mind
Main Article: Mind dualism
In philosophy of mind, dualism is any of a narrow variety of views about the relationship between mind and matter, which are seen as totally different kinds of things. This type of dualism is sometimes referred to as "mind and body". This is in contrast to monism, which views mind and matter as being ultimately the same kind of thing. See also Cartesian dualism, substance dualism, epiphenomenalism.
Usage in philosophy of science
Main Article: The problem of other minds
In philosophy of science, dualism often refers to the dichotomy between the "subject" (the observer) and the "object" (the observed). Some critics of Western science see this kind of dualism as a fatal flaw in science. In part, this has something to do with potentially complicated interactions between the subject and the object, of the sort discussed in the social construction literature.
Usage in physics
Main Article: Wave-particle duality
In physics, dualism refers generally to the duality of waves and particles.
