pantheism, the doctrine that the universe conceived of as a whole is God and, conversely, that there is no God but the combined substance, forces, and laws that are manifested in the existing universe. The cognate doctrine of panentheism asserts that God includes the universe as a part though not the whole of his being.
Both “pantheism” and “panentheism” are terms of recent origin, coined to describe certain views of the relationship between God and the world that are different from that of traditional theism. As reflected in the prefix “pan-” (Greek pas, “all”), both of the terms stress the all-embracing inclusiveness of God, as compared with his separateness as emphasized in many versions of theism. On the other hand, pantheism and panentheism, since they stress the theme of immanence—i.e., of the indwelling presence of God—are themselves versions of theism conceived in its broadest meaning. Pantheism stresses the identity between God and the world, panentheism (Greek en, “in”) that the world is included in God but that God is more than the world.
The adjective “pantheist” was introduced by the Irish Deist John Toland in the book Socinianism Truly Stated (1705). The noun “pantheism” was first used in 1709 by one of Toland’s opponents. The term “panentheism” appeared much later, in 1828. Although the terms are recent, they have been applied retrospectively to alternative views of the divine being as found in the entire philosophical traditions of both East and West.
