...Though exposed to the same anguish, virtue and vice are not the same thing. For as the same fire causes gold to glow brightly, and chaff to smoke; and under the same flail the straw is beaten small, while the grain is cleansed; and as the lees are not mixed with the oil, though squeezed out of the vat by the same pressure, so the same violence of affliction proves, purges, clarifies the good, but damns, ruins, exterminates the wicked.
