90. Let anger be guarded against. Cic. de Off. I. 25, § 89. If it cannot, however, be averted, let it be kept within bounds. For indignation is a terrible incentive to sin. It disorders the mind to such an extent as to leave no room for reason. The first thing, therefore, to aim at, if possible, is to make tranquillity of character our natural disposition by constant practice, by desire for better things, by fixed determination. But since passion is to a large extent implanted in our nature and character, so that it cannot be uprooted and avoided, it must be checked by reason, if, that is, it can be foreseen. And if the mind has already been filled with indignation before it could be foreseen or provided against in any way, we must consider how to conquer the passion of the mind, how to restrain our anger, that it may no more be so filled.
