Nominalists, Nominalism [from Latin
nomen name] In the 11th century, Scholastic controversy arose between the Nominalists and Realists, as to whether substantive reality should be ascribed to particulars or to universals. The Nominalists held that nothing exists but individuals, and that universals are mere names invented to express the qualities of particular things. Thus the conception "man" is a mere abstract idea, a figment of the mind, devised to express certain qualities which we have abstracted from our experience of individual men, but having no existence except as a name. The Realists, on the contrary, maintained that universals alone have substantive reality, and that they exist independently of, and prior to, the individuals, which are derivative from them or expressive of them. The controversy dates back to Aristotle's question as to whether genera, species, and abstract nouns are real or only convenient abstractions and ways of speaking.
Intermediate between these doctrines is that of the Conceptualists, identified with the name of Abelard, who held that universals, while they exist only in the mind, yet correspond to real similarities in things, which previous to creation existed in the mind of God. These notions are well illustrated by the question as to the meaning of such words as motion, force, heat, or light. Are the things studied by science under those names generalizing terms, existing only in the mind and posterior to the objects which manifest them; or are they realities in themselves, prior to the objects, and of which the objects are manifestations?
