Having treated of God's existence (Q2) and what we can know of His essence (QQ3-13), we turn now to consider His operations, beginning with five questions on the operations of His intellect:
God's knowledge (Q14).
The ideas (Q15), which exist in His knowledge.
Truth (Q16) in God, for knowledge is of things that are true.
Falsity (Q17) in God.
The life of God (Q18), since to understand belongs to living beings.
