Book 3
1.89
Beauty has three divisions. The first is the object of praise, as of form fair to see. Another is serviceable; thus an instrument, a house and the like are beautiful for use. Other things again which relate to customs and pursuits and the like are beautiful because beneficial. Of beauty, then, one kind is matter for praise, another is for use, and another for the benefit it procures.
1.90
The soul has three divisions. One part of it is rational, another appetitive, and a third irascible. Of these the rational part is the cause of purpose, reflection, understanding and the like. The appetitive part of the soul is the cause of desire of eating, sexual indulgence and the like, while the irascible part is the cause of courage, of pleasure and pain, and of anger. Thus one part of the soul is rational, another appetitive, and a third irascible.
1.90
Of perfect virtue there are four species: prudence, justice, bravery and temperance.
1.91
Of these prudence is the cause of right conduct, justice of just dealing in partnerships and commercial transactions. Bravery is the cause which makes a man not give way but stand his ground in alarms and perils. Temperance causes mastery over desires, so that we are never enslaved by any pleasure, but lead an orderly life. Thus virtue includes first prudence, next justice, thirdly bravery, and lastly temperance.
1.91
Rule has five divisions, one that which is according to law, another according to nature, another according to custom, a fourth by birth, a fifth by force.
