I. If no part of the Division agrees to a thing, neither doth the thing divided agree with it.
Thus, because the notion neither of a Spirit nor Body, doth agree to Substantial Forms (save only the Soul of Man.) Therefore, Substantial Forms cannot be Substances.
II. Every Division must be entire, that is, it Enumerates all and every Part belonging to a thing.
For should any part belonging to a thing, be omitted in the Division, there could not be an Adequate Enumeration of the Parts, neither con∣sequently would the thing, by means of such a Division, be distinctly perceived. Thus the Di∣vision of a Man into Sound and Sick, is not Ade∣quate, because there is a kind of Middle State, as, is that of a Man, that is recovering from Sickness. But the Division of Hand into Right and Left; of a Line into Right and Crooked; of a Number into Even and Odd, is Adequate because it Enu∣merates all and every Part.
III. The Parts of a Division must be opposit.
This Axiom follows from the foregoing. Thus things are better divided into Material and Immate∣rial, than into Visible and Invisible; because some Invisible things, as a very clear Air, and our Breath, are not by nature distinct from Visibles.
