THIS IS THE FORMULATION OF THE one antipathy by modern 'nominalistic' metaphysics, as Grice has it in "Actions and Events" (PPQ, vol. 67, p. 2):

"In recent times," he writes, after reviewing the Ontolgical exhuberance of R. Robinson ("You name it") and the solitary confinement of "The Kingdom of Prussia", as reported by Broad, "there has been a strong tendency to restrict recognition [of existence] to individual entities, excluding of course, all abstract entities except sets" (p. 2)
