168. As few know anything about the enlightenment in which the understanding of a man is who is taught by the Lord, something will be said of it. There is inner and outer enlightenment from the Lord, and inner and outer enlightenment from oneself. Inner enlightenment from the Lord consists in man's perceiving on first hearing something whether it is true or not; outer enlightenment consists in thought from this. Inner enlightenment from oneself is simply from confirmation and outer enlightenment merely from information. We will say something of each. [2] By inner enlightenment from the Lord a rational person perceives about many things the moment he hears them whether they are true or not; for example, that love is the life of faith or that faith lives by love. By interior enlightenment a person also perceives that a man wills what he loves and does what he wills, consequently that to love is to do; again, that a man wills and does whatever he believes from love, and therefore to have faith is also to do; and that the impious man cannot have love for God or faith then in Him. By inner enlightenment a rational man also perceives the following truths at once on hearing them: God is one; He is omnipresent; all good is from Him; all things have relation to good and truth; all good is from good itself and all truth from truth itself. A man perceives these and other similar truths inwardly in himself on hearing them and does so because he possesses a rationality which is in heaven's enlightening light. [3] Outer enlightenment is enlightenment of one's thought from this inner enlightenment. One's thought is in this enlightenment so far as it remains in the perception it has from inner enlightenment and so far as it possesses knowledge of good and truth, for it gets from this knowledge reasons confirming it. Thought from outer enlightenment sees a matter on both sides; on the one, it sees reasons which confirm it, and on the other, the appearances that weaken it; it dispels these and assembles the reasons. [4] Inner enlightenment from oneself, however, is quite different. By it one regards a matter on one side only, and having confirmed it sees it in light apparently like that just spoken of, but it is a wintry light. For example, a judge who judges unjustly in view of gifts or gain, once he has confirmed the judgment by law and reason sees in it nothing but justice. Some judges see the injustice but not wanting to see it, they keep it out of sight and blind themselves and so do not see. The same is true of a judge who renders judgments out of friendship, or to gain favor, or on account of relationship.
