Many person might have achieved wisdom had they not supposed that they already possessed it.
Seneca the YoungerWhat if a man save my life with a draught that was prepared to poison me? The providence of the issue does not at all discharge the obliquity of the intent. And the same reason holds good even in religion itself. It is not the incense, or the offering that is acceptable to God, but the purity and devotion of the worshipper.
