Nominalism. The position opposed to realism, denying the reality of all
universals. The more moderate nominalists, of whom Ockham is the
representative, only rejected the independent existence of these, but
admitted that there were such conceptions in the mind. (See
Conceptualism.) The extreme nominalists such as probably Roscelin, and
certainly Hobbes, Berkeley, and Hume, denied even the latter position.
