PLURALISM. — In opposition to monism (q.v.), it is the doctrine according to which reality is constituted by multiple and diverse entities.
Aristotelian philosophy may be called pluralistic, as it admits a distinction in nature between the Unmoved Mover and the separate Intelligences on the one hand, and the corporeal world on the other; and even within each of these two spheres, it admits the existence of different entities, specified by substantial form. All Scholastic philosophies are pluralistic; in the modern era, Leibnizian philosophy is pluralistic, for which the monads, the primary substances that underlie reality, are specifically diverse and irreducible to one another. Pluralistic are all those contemporary philosophies that oppose the reduction of reality to a single type: to matter alone or to spirit alone; e.g., the philosophy of H. Lotze (*Metaphysik*, Leipzig 1841), of W. James (*A Pluralistic Universe*, New York – London 1909).
