CHAP. IV. Of the Five Ʋniversals, or Predicables.
I. There is a twofold Genus of Beings or Entities. WE are to suppose in the first Place, that there are Beings that have some reality in the Nature of things; and whose Attributes belong to them, whether the Understanding think so or not. Such are all Substances, and all Attributes or Modes, which denominate or vary them. Others again derive all the Being they have from the In∣tellect, on the operation whereof they so depend, as to vanish away upon its Cessation; as are all those which are called Entia Rationis (Entities of Reason) in the Schools.
II. Universals are only Modes of Thinking. In the Second place we are to suppose, that no∣thing else is to be understood by the word Uni∣versal, than that which agrees or is attributable to many things; as the word Substance, which agrees to Body and Spirit. Wherefore all Universals are in our Understanding, and to speak properly, are only Modes of Thinking. For seeing all Na∣tural things are Singular and distinct from each other, these Universals can have no Unity, but what our Understanding gives them. By Example, Two Lines if separately consider'd, cannot be said to agree in the Notion of a Line; because in the Conception of the one, is included the Negation of the other; wherefore to the end they may agree, we must first frame an Idea, which may serve us for the conceiving of all Lines that are like one another. Thus we put some Common Name upon all those things which are represented by an Idea, which Name is commonly called an Universal. And thus that famous Number of Universals, which hath rack'd so many Brains, may easily be salved.
III. How Uni∣versals are formed. For Example, When we consider Substance extended in Length, Breadth and Depth, we frame an Idea of it, and call it the Idea of a Body, which afterwards is of use to us for the representing of all Bodies to our Mind. But seeing that many of them are distinguish'd by Species, as into Living Bodies
