Of the Distinction of Things in General

After considering the production of creatures, we come to the consideration of the distinction of things. This consideration will be threefold—first, of the distinction of things in general; secondly, of the distinction of good and evil; thirdly, of the distinction of the spiritual and corporeal creature.

Under the first head, there are three points of inquiry:

(1) The multitude or distinction of things.

(2) Their inequality.

(3) The unity of the world.
