Whether folly is a sin?

❌ Objection 1 : It would seem that folly is not a sin. For no sin arises in us from nature. But some are fools naturally. Therefore folly is not a sin.

❌ Objection 2 : Further, "Every sin is voluntary," according to Augustine (De Vera Relig. xiv). But folly is not voluntary. Therefore it is not a sin.

❌ Objection 3 : Further, every sin is contrary to a Divine precept. But folly is not contrary to any precept. Therefore folly is not a sin.
