"some certain man," yet is in no subject. Others, again, are in a subject, yet are not predicated of any subject, (I mean by a thing being in a subject, that which is in any thing not as a part, but which cannot subsist without that in which it is,) as "a certain grammatical art" is in a subject, "the soul," but is not predicated of any; and "this white thing" is in a subject, "the body," (for all "colour" is in "body,") but is predicated of no subject. But some things are both predicated of and are in a subject, as "science" is in a subject—"the soul," but is predicated of a subject, namely, "grammar." Lastly, some are neither in, nor are predicated of, any subject, as "a certain man" and "a certain horse," for nothing of this sort is either in, or predicated of, a certain subject. 3. Individuals, not predicated of a subject. In short, individuals, and whatever is one in number, are predicated of no subject, but nothing prevents some of them from being in a subject, for "a certain grammatical art" is amongst those things which are in a subject, but is not predicated of any subject.
Chap. III.—Of the connexion between Predicate and Subject.
- ↑ Genera, species, and differences, differ according to their predicaments, hence in each predicament, there are genera, species, and differences. Those genera also, have a mutual arrangement, one of which is under the other, as "flying" under "animal," but those are not mutually arranged, one of which, is not ranked under the other, as "animal" and "science." Upon the application of this general rule, see Whately and Hill's Logic, especially the latter, in respect to summa and subaltern genera, and their cognates, pages 56, 57. Properly speaking, there can be only one highest genus, namely, Being; though relatively a subaltern term, may at any time, be assumed as the summum genus, as "substance," "animal," etc.
