Selection from Divine Providence ~ Emanuel Swedenborg
As few know anything about the enlightenment that the understanding of a man who is taught by the Lord is in, something shall be said about it.There is an interior and an exterior enlightenment from the Lord; and there is an interior and an exterior enlightenment from man.
A man who is rational from interior enlightenment from the Lord immediately perceives, when he hears them, whether many things are true or not true; for example, that love is the life of faith, that is, that faith lives from love. Also by interior enlightenment man perceives that whatever one loves he wills, and what he wills he does, consequently that to love is to do; and again, that whatever man believes from love, this too he wills and does, consequently to have faith is to do; also that a wicked man cannot have love of God, thus neither faith in God.
By interior enlightenment a rational man perceives as soon as he hears it that God is One; that He is omnipresent; that all good is from Him; also that all things have relation to good and truth; and that all good is from Good itself, and all truth from Truth itself. Man perceives these things and other like things interiorly in himself when he hears them; and he has this perception because he has rationality that is in the light of heaven, which gives enlightenment.
Exterior enlightenment is an enlightenment of the thought that is from the interior enlightenment; and the thought is in such enlightenment so far as it continues in the perception that it has from interior enlightenment, and also so far as it has knowledges of truth and good; for from these it draws the reasons by means of which it confirms. Thought from this exterior enlightenment sees a thing from both sides; on the one it sees the reasons that confirm, on the other the appearances that invalidate; the latter it disperses, the former it collects.
Interior enlightenment from man is wholly different. By it man sees a subject on one side and not on the other; and when he has confirmed it he sees it in a light apparently like the light spoken of above, but it is a winter light. For example, a judge who judges unjustly because of gifts or for the sake of gain, when he has confirmed his decision by the laws and by reasons, sees nothing but justice in it. To some the injustice may be evident, but as they do not wish to see it they mystify and blind themselves, and thus do not see. The same is true of a judge who is influenced in his decisions by friendship, or by a desire to gain favor, or by the ties of relationship.
Such men regard in the same way every thing that they hear from the lips of a man in authority, or a man of celebrity, or that they have hatched out from their own intelligence. They are rationally blind; for they have their vision from falsities, which they confirm; and falsity closes the sight, while truth opens it. Such see no truth from the light of truth, and no justice from a love of justice, but only from the light of confirmation, which is a delusive light. In the spiritual world they appear like faces without heads, or like faces that resemble human faces behind which there are wooden heads; and they are called rational animals, because they have rationality potentially. Those have exterior enlightenment from man, who think and talk from mere knowledge impressed on the memory. Such are scarcely able to confirm any thing from themselves.
