Supposing for the present that these are two separate conceptions (for I am not yet prepared to give my own opinion); what prevents the existence of still a third—which is none the less a Good? I remarked a little while ago that a “field” was one thing, and the “possession of a field” another; of course, for possessor and possessed are of different natures; the latter is the land, and the former is the man who owns the land. But with regard to the point now under discussion, both are of the same nature—the possessor of wisdom, and wisdom itself.
