if not complementary, neither can they be parts. But God being by nature rich in pity, in consequence of His own goodness, cares for us, though neither portions of Himself, nor by nature His children. And this is the greatest proof of the goodness of God: that such being our relation to Him, and being by nature wholly estranged. He nevertheless cares for us. For the affection in animals to their progeny is natural, and the friendship of kindred minds is the result of intimacy. But the mercy of God is rich toward us, who are in no respect related to Him; I say either in our essence or nature, or in the peculiar energy of our essence, but only in our being the work of His will.

"Transgressions catch a man; and in the cords of his own sins each one is bound."[1] And God is without blame. And in reality, "blessed is the man who feareth alway through piety."[2]
CHAPTER XVII.
ON THE VARIOUS KINDS OF KNOWLEDGE.
As, then, Knowledge (ἐπιστήμη) is an intellectual state, from which results the act of knowing, and becomes apprehension irrefragable by reason; so also ignorance is a receding impression, which can be dislodged by reason. And that which is overthrown as well as that which is elaborated by reason, is in our power. Akin to Knowledge is experience, cognition (εἴδησις), Comprehension (σύνεσις), perception, and Science. Cognition (εἴδησις) is the knowledge of universals by species; and Experience is comprehensive knowledge, which investigates the nature of each thing. Perception (νόησις) is the knowledge of intellectual objects; and Comprehension (σύνεσις) is the knowledge of what is compared, or a comparison that cannot be annulled, or the faculty of comparing the
