If Fortune makes a wicked man prosperous and a good man poor, there is no need to wonder. For the wicked regard wealth as everything, the good as nothing. And the good fortune of the bad cannot take away their badness, while virtue alone will be enough for the good. X. _Concerning Virtue and Vice._ The doctrine of Virtue and Vice depends on that of the Soul. When the irrational soul enters into the body and immediately produces Fight and Desire, the rational soul, put in authority over all these, makes the soul tripartite, composed of Reason, Fight, and Desire. Virtue in the region of Reason is Wisdom, in the region of Fight is Courage, in the region of Desire it is Temperance: the virtue of the whole Soul is Righteousness. It is for Reason to judge what is right, for Fight in obedience to Reason to despise things that appear terrible, for Desire to pursue not the apparently desirable, but, that which is with Reason desirable. When these things are so, we have a righteous life; for righteousness in matters of property is but a small part of virtue. And thus we shall find all four virtues in properly trained men, but among the untrained one may be brave and unjust, another temperate and stupid, another prudent and unprincipled. Indeed these qualities should not be called Virtues when they are devoid of Reason and imperfect and found in irrational beings. Vice should be regarded as consisting of the opposite elements. In Reason it is Folly, in Fight, Cowardice, in Desire, Intemperance, in the whole soul, Unrighteousness. The virtues are produced by the right social organization and by good rearing and education, the vices by the opposite. XI. _Concerning right and wrong Social Organization._[214:1] Constitutions also depend on the tripartite nature of the Soul. The rulers are analogous to Reason, the soldiers to Fight, the common folk to Desires. Where all things are done according to Reason and the best man in the nation rules, it is a Kingdom; where more than one rule according to Reason and Fight, it is an Aristocracy; where the government is according to Desire and offices depend on money, that constitution is called a Timocracy. The contraries are: to Kingdom tyranny, for Kingdom does all things with the guidance of reason and tyranny nothing; to Aristocracy oligarchy, when not the best people but a few of the worst are rulers; to Timocracy democracy, when not the rich but the common folk possess the whole power. XII. _The origin of evil things; and that there is no positive evil._ The Gods being good and making all things, how do evils exist in the world? Or perhaps it is better first to state the fact that, the Gods being good and making all things, there is no positive evil, it only comes by absence of good; just as darkness itself does not exist, but only comes about by absence of light.
