Monotheism is the belief in the existence of one god or, stated in other terms, that God is one. As such it is distinguished from polytheism, the belief in the existence of a number of gods, and atheism, the denial of the belief in any god or gods at all. The God of monotheism is the one real god that is believed to exist or, in any case, that is acknowledged as such. His essence and character are believed to be unique and fundamentally different from all other beings that can be considered more or less comparable; e.g., the gods of other religions. The religious term monotheism is not identical with the philosophical term monism, referring to the view that the universe has its origin in one basic principle (e.g., mind, matter) and that its structure is one unitary whole in accordance with this principle; that is, that there is only a single kind of reality, whereas, for monotheism, there are two basically different realities: God and the universe.
