The logical division of Things and their Attributes

Of things talked about:

• some are enunciated after a complex way
  • An example is:
    • “A man runs”
    • “A man conquers”
• others after an incomplex way
  • Examples are:
    • “man,” “ox,” “runs,” “conquers”

Likewise also some things are predicated of a certain subject, yet are in no subject, as “the man” is predicated of a subject, i. e. of “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.

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.
