19. No one who, from confirmation and life, is in evil and in the falsity from it, can know what good and truth are; for he believes his own evil to be good, and thus his falsity to be truth. But every one who, by confirmation and life, is in good and in the truth from it, can know what evil and falsity are. The reason is, that all good, with its truth, is in its essence heavenly: and what is not in its essence heavenly, is still from a heavenly origin; but all evil, with its falsity, is in its essence hellish, and what is not hellish in its essence, is still hellish by origin; and everything heavenly is in light, but everything hellish in darkness.
