produced: for in the act of coming into being the imperfect must be made before the perfect: and it is impossible that anything should be created, save by God alone.
In proof whereof it must be borne in mind that the higher the cause, the more numerous the objects to which its causation extends. Now the underlying principle in things is always more universal than that which informs and restricts it; thus, being is more universal than living, living than understanding, matter than form. The more widely, then, one thing underlies others, the more directly does that thing proceed from a higher cause. Thus the thing that underlies primarily all things, belongs properly to the causality of the supreme cause. Therefore no secondary cause can produce anything, unless there is presupposed in the thing produced something that is caused by a higher cause. But creation is the production of a thing in its entire substance, nothing being presupposed either uncreated or created. Hence it remains that nothing can create except God alone, Who is the first cause. Therefore, in order to show that all bodies were created immediately by God, Moses said: "In the beginning God created heaven and earth."
Reply Obj. 1: In the production of things an order exists, but not such that one creature is created by another, for that is impossible; but rather such that by the Divine wisdom diverse grades are constituted in creatures.
Reply Obj. 2: God Himself, though one, has knowledge of many and different things without detriment to the simplicity of His nature, as has been shown above (Q. 15, A. 2); so that by His wisdom He is the cause of diverse things as known by Him, even as an artificer, by apprehending diverse forms, produces diverse works of art.
Reply Obj. 3: The amount of the power of an agent is measured not only by the thing made, but also by the manner of making it; for one and the same thing is made in one way by a higher power, in another by a lower. But the production of finite things, where nothing is presupposed as existing, is the work of infinite power, and, as such, can belong to no creature.
FOURTH ARTICLE [I, Q. 65, Art. 4]
Whether the Forms of Bodies Are from the Angels?
Objection 1: It would seem that the forms of bodies come from the angels. For Boethius says (De Trin. i): "From forms that are without matter come the forms that are in matter." But forms that are without matter are spiritual substances, and forms that are in matter are the forms of bodies. Therefore, the forms of bodies are from spiritual substances.
Obj. 2: Further, all that is such by participation is reduced to that which is such by its essence. But spiritual substances are forms essentially, whereas corporeal creatures have forms by participation. Therefore the forms of corporeal things are derived from spiritual substances.
Obj. 3: Further, spiritual substances have more power of causation than the heavenly bodies. But the heavenly bodies give form to things here below, for which reason they are said to cause generation and corruption. Much more, therefore, are material forms derived from spiritual substances.
On the contrary, Augustine says (De Trin. iii, 8): "We must not suppose that this corporeal matter serves the angels at their nod, but rather that it obeys God thus." But corporeal matter may be said thus to serve that from which it receives its form. Corporeal forms, then, are not from the angels, but from God.
