审慎, 节制, 坚韧, 与正义

Prudence is the knowledge of what is to be desired and what is to be avoided.

Fortitude is the disposition of the soul by which we have no fear of misfortune or of the loss of things that are not in our power.

Temperance is the disposition that checks and restrains the desire for things that it is wicked to desire.

Justice is the virtue by which all people are given their due.

People are happy when they love their own good will, in comparison with which they scorn everything that is called good but can be lost even though one wills to retain it.

Even if we have never been wise, it is by the will that we lead and deserve a praiseworthy and happy life, or a contemptible and unhappy one.

So if by our good will we love and embrace that will, and prefer it to everything that we cannot retain simply by willy to retain it, then, as the argument showed, we will possess those very virtues that constitute an upright and honorable life. From this it follows that all who will to live upright and honorable lives, if they will this more than they will transitory goods, attain such a great good so easily that they have it by the very act of willing to have it.
