Reading edition
The abstract term is coined for the express purpose of marking one part of a cluster simultaneously present to the mind, and fixing attention upon it without the other parts—but the concrete term is often made to serve the same purpose, by means of the adverb quatenus, κάθοσον, ᾗ &c. These phrases are frequent both in Plato and Aristotle: the stock of abstract terms was in their day comparatively small. It is needless to multiply illustrations of that which pervades the compositions of both: a very good one appears in Plato, Republ. I., p. 340 D, 341 C, 342.
