The life of God (18), since to understand belongs to living beings. Truth (16) in God, for knowledge is of things that are true. The ideas (15), which exist in His knowledge. OPERATIONS (INTELLECT): God's knowledge (14). His immutability (9), and His eternity (10) following on His immutability. His perfection: and because everything in so far as it is perfect is called good, we shall speak of His goodness (6)-and goodness in general (5)-as well as His perfection (4). His simplicity (3) or lack of composition. So to study Him, we study what He has not-such as composition and motion.
