Pantheism

Pantheism is a word derived from the Greek roots pan (meaning "all") and theos (meaning "God"). It is the belief that everything composes an all-encompassing, immanent God, or that the Universe (or Nature) is identical with divinity. Pantheists thus do not believe in a personal or anthropomorphic god, but differ in exact interpretation of the term.

Pantheism was popularized in the modern era as both a theology and philosophy based on the work of Baruch Spinoza, whose treatise, Ethics, was an answer to Descartes' famous dualist theory that the body and spirit are separate. Spinoza held that the two are the same, and this monism is a fundamental quality of his philosophy. He was described as a "God-intoxicated man," and used the word God to describe the unity of all substance. Though the term Pantheism was not coined until after his death, Spinoza is regarded as the most celebrated advocate of pantheism.
