19. No one who by conviction and manner of life has chosen evil and the falsity which comes of it can know what good and truth are, because he believes that his own evil is good and thus that his own falsity is truth. However, everyone who by conviction and manner of life has chosen good and the truth which comes of it can know what evil and falsity are. The reason is that all good, and the truth which comes of it, is in its essence heavenly, and that which is not in its essence heavenly is still of heavenly origin. But all evil and the falsity which comes of it is in its essence hellish, and what is not in its essence hellish still comes from that origin. Everything heavenly is bathed in light and everything hellish is sunk in darkness.
