ABSTRACT
AS Nelson Goodman has rightly pointed out, the distinction between abstract and concrete is not the same as that between universal and particular (The Structure of Appearance (SA), pp. 200–201). Since, however, Goodman's definitions of these terms are rigged in the midst of his rather peculiar reconstruction, Bince those definitions therefore involve the use of the term “coneretum” in the definiens, and since the term “concretum” involves a possibly dubious maneuver in its explication (cf. “A Query to Mr. Goodman” by the present writer, Philosophical Studies, December 1957, pp. 81–85), I prefer to formulate my own explication of “concrete” and “abstract.”
