The classical realist objectively notes that being is analogous . God's existence, which is identical with his essence, does not exhaust all the possibilities of existence since there exist natures which possess existence, not in their own right as natures, but by participation in existence from God who is existence itself. It is true that whatever is real is one, but this unity is analogous. God is one in the purest ontological unity. The cosmos is one accidentally as a union of many substances.
Man is one in species, but many in individuals.
This man is one as a person, but many in the potential parts that compose him physically. Materialism Must be Rejected Materialism as a philosophy is repugnant to reason. Materialism holds that everything is one kind of being, namely matter, and that matter is eternal and unproduced. The atomism of Leucippus and Democritus is the first known formulation of the materialistic philosophy. These ancient Greeks were the first to maintain in a philosophical system that the totality of reality is purely material.
