But it is a great error to take this passion either for a companion or for an assistant to virtue; that makes a man incapable of those necessary counsels by which virtue is to govern herself. Those are false and inauspicious powers, and destructive of themselves, which arise only from the accession and fervor of disease. Reason judges according to right; anger will have every thing seem right, whatever it does, and when it has once pitched upon a mistake, it is never to be convinced, but prefers a pertinacity, even in the greatest evil, before the most necessary repentance.
