hings are immediately governed by God?

Objection 1: It would seem that all things are governed by God
immediately. For Gregory of Nyssa (Nemesius, De Nat. Hom.) reproves
the opinion of Plato who divides providence into three parts. The
first he ascribes to the supreme god, who watches over heavenly
things and all universals; the second providence he attributes to
the secondary deities, who go the round of the heavens to watch over
generation and corruption; while he ascribes a third providence to
certain spirits who are guardians on earth of human actions.
Therefore it seems that all things are immediately governed by God.

Obj. 2: Further, it is better that a thing be done by one, if
possible, than by many, as the Philosopher says (Phys. viii, 6). But
God can by Himself govern all things without any intermediary cause.
Therefore it seems that He governs all things immediately.

Obj. 3: Further, in God nothing is defective or imperfect. But it
seems to be imperfect in a ruler to govern by means of others; thus
an earthly king, by reason of his not being able to do everything
himself, and because he cannot be everywhere at the same time,
requires to govern by means of ministers. Therefore God governs all
things immediately.

_On the contrary,_ Augustine says (De Trin. iii, 4): "As the lower
and grosser bodies are ruled in a certain orderly way by bodies of
greater subtlety and power; so all bodies are ruled by the rational
spirit of life; and the sinful and unfaithful spirit is ruled by the
good and just spirit of life; and this spirit by God Himself."

_I answer that,_ In government there are two things to be considered;
the design of government, which is providence itself; and the
execution of the design. As to the design of government, God governs
all things immediately; whereas in its execution, He governs some
things by means of others.

The reason of this is that as God is the very essence of goodness,
so everything must be attributed to God in its highest degree of
goodness. Now the highest degree of goodness in any practical order,
design or knowledge (and such is the design of government) consists
in knowing the individuals acted upon; as the best physician is not
the one who can only give his attention to general principles, but
who can consider the least details; and so on in other things.
Therefore we must say that God has the design of the government of
all things, even of the very least.
