Whether prudence of the flesh is a sin?

❌ Objection 1 : It would seem that prudence of the flesh is not a sin. For prudence is more excellent than the other moral virtues, since it governs them all. But no justice or temperance is sinful. Neither therefore is any prudence a sin.

❌ Objection 2 : Further, it is not a sin to act prudently for an end which it is lawful to love. But it is lawful to love the flesh, "for no man ever hated his own flesh" (Eph. 5:29). Therefore prudence of the flesh is not a sin.

❌ Objection 3 : Further, just as man is tempted by the flesh, so too is he tempted by the world and the devil. But no prudence of the world, or of the devil is accounted a sin. Therefore neither should any prudence of the flesh be accounted among sins.
