account of the existence of things in
the angelic mind.

_On the contrary,_ Augustine (Gen. ad lit. iv, 22, 31; De Civ. Dei
xii, 7, 20) divides the knowledge of the angels into morning and
evening knowledge.

_I answer that,_ The expression "morning" and "evening" knowledge was
devised by Augustine; who interprets the six days wherein God made all
things, not as ordinary days measured by the solar circuit, since the
sun was only made on the fourth day, but as one day, namely, the day
of angelic knowledge as directed to six classes of things. As in the
ordinary day, morning is the beginning, and evening the close of day,
so, their knowledge of the primordial being of things is called
morning knowledge; and this is according as things exist in the Word.
But their knowledge of the very being of the thing created, as it
stands in its own nature, is termed evening knowledge; because the
being of things flows from the Word, as from a kind of primordial
principle; and this flow is terminated in the being which they have in
themselves.

Reply Obj. 1: Evening and morning knowledge in the angelic knowledge
are not taken as compared to an admixture of darkness, but as
compared to beginning and end. Or else it can be said, as Augustine
puts it (Gen. ad lit. iv, 23), that there is nothing to prevent us
from calling something light in comparison with one thing, and
darkness with respect to another. In the same way the life of the
faithful and the just is called light in comparison with the wicked,
according to Eph. 5:8: "You were heretofore darkness; but now, light
in the Lord": yet this very life of the faithful, when set in
contrast to the life of glory, is termed darkness, according to 2
Pet. 1:19: "You have the firm prophetic word, whereunto you do well
to attend, as to a light that shineth in a dark place." So the
angel's knowledge by which he knows things in their own nature, is
day in comparison with ignorance or error; yet it is dark in
comparison with the vision of the Word.

Reply Obj. 2: The morning and evening knowledge belong to the day,
that is, to the enlightened angels, who are quite apart from the
darkness, that is, from the evil spirits. The good angels, while
knowing the creature, do not adhere to it, for that would be to turn
to darkness and to night; but they refer this back to the praise of
God, in Whom, as in their principle, they know all things.
Consequently after "evening" there is no night, but "morni
