THE "SUMMA THEOLOGICA"

QUESTION XlV.
OF GOD'S KNOWLEDGE.
(In Sixtee_ Articles.)
HAVING considered what belongs to the divine substance,
we have now to treat of God's operation. And since one
kind of operation is immanent, and another kind of operation
proceeds to the exterior effect, we treat first of knowledge
and of will (for understanding abides in the intelligent
agent, and will is in the one who wills); and afterwards of
the power of God, the principle of the divine operation as
proceeding to the exterior effect. Now because to understand
is a kind of life, after treating of the divine knowledge,
we consider the divine life. And as knowledge concerns
truth, we consider truth and falsehood. Further, as everything
known is in the knower, and the types of things
as existing in the knowledge of God are called ideas, to the
consideration of knowledge will be added the treatment
of ideas.
Concerning knowledge, there are sixteen points for inquiry:
(1) Whether there is knowledge in God ? (2) Whether
GOd understands Himself ? (3) Whether He comprehends
Himself ? (4) Whether His understanding is His substance
? (5) Whether He understands other things besides
Himself ? (6) Whether He has a proper knowledge of
them ? (7) Whether the knowledge of God is discursive ?
(8) Whether the knowledge of God is the cause of things ?
(9) Whether God has knowledge of non-existing things ?
(IO) Whether He has knowledge of evil ? (II) Whether
He has knowledge of individual things ? (12) Whether
He knows the infinite ? (13) Whether He knows future
contingent things ? (14) Whether He knows enunciable
