and to desire unlawful pleasures. Yet, for all that, we do not of necessity sin. We sin when we yield to these tendencies and do what they suggest. The simple proneness to evil, devoid of all wilful yielding is therefore not wrong. Why? Because we cannot help it; that is a good and sufficient reason.

These passions may lie dormant in our nature without soliciting to evil; they may, at any moment, awake to action with or without provocation. The sight of an enemy or the thought of a wrong may stir up anger; pride may be aroused by flattery, applause or even compliments; the demon of lust may make its presence known and felt for a good reason, for a slight reason, or for no reason at all; gluttony shows its head at the sight of food or drink, etc.
