THIRD ARTICLE [I, Q. 109, Art. 3]

Whether There Is Enlightenment in the Demons?

Objection 1: It would seem that enlightenment is in the demons. For

enlightenment means the manifestation of the truth. But one demon can

manifest truth to another, because the superior excel in natural

knowledge. Therefore the superior demons can enlighten the inferior.

Obj. 2: Further, a body abounding in light can enlighten a body

deficient in light, as the sun enlightens the moon. But the superior

demons abound in the participation of natural light. Therefore it

seems that the superior demons can enlighten the inferior.

_On the contrary,_ Enlightenment is not without cleansing and

perfecting, as stated above (Q. 106, A. 1). But to cleanse does

not befit the demons, according to the words: "What can be made clean

by the unclean?" (Ecclus. 34:4). Therefore neither can they enlighten.

_I answer that,_ There can be no enlightenment properly speaking among

the demons. For, as above explained (Q. 107, A. 2), enlightenment

properly speaking is the manifestation of the truth in reference to

God, Who enlightens every intellect. Another kind of manifestation of

the truth is speech, as when one angel manifests his concept to

another. Now the demon's perversity does not lead one to order another

to God, but rather to lead away from the Divine order; and so one

demon does not enlighten another; but one can make known his mental

concept to another by way of speech.

Reply Obj. 1: Not every kind of manifestation of the truth is

enlightenment, but only that which is above described.

Reply Obj. 2: According to what belongs to natural knowledge, there

is no necessary manifestation of the truth either in the angels, or

in the demons, because, as above explained (Q. 55, A. 2; Q. 58, A. 2;

Q. 79, A. 2), they know from the first all that belongs to their

natural knowledge. So the greater fulness of natural light in the

superior demons does not prove that they can enlighten others.
