(1) Every virtue is perfected, as was shown by us in the beginning, from reason, deliberate choice, and power. Each of these, however, is not by itself a part of virtue, but the cause of it. Such therefore, as have the intellective and gnostic part of virtue , are denominated skilful and intelligent; but such as have the ethical and pre-elective part of it, are denominated useful and equitable. Since however, man is naturally adapted to act unjustly from exciting causes; and these are three, the love of pleasure in corporeal enjoyments; avarice, in the accumulation of wealth; and ambition, in surpassing those that are equal and similar to him;—this being the case, it is necessary to know, that it is possible to oppose to these such things as procure fear, shame, and desire in men; viz. fear through the laws, shame through the Gods, and desire through the energies of reason. Hence, it is necessary that youth should be taught from the first to honor the Gods and the laws. For from these, it will be manifest, that every human work, and every kind of human life, by the participation of sanctity and piety, will sail prosperously [over the sea of generation].

(3) Since however, the virtue of manners is conversant with the passions, but of the passions pleasure and pain are supreme, it is evident that virtue does not consist in extirpating the passions of the soul, pleasure and pain, but in co-harmonizing them. For neither does health, which is a certain apt mixture of the powers of the body, consist in expelling the cold and the hot, the moist and the dry; but in these being [appropriately] mingled together. For it is as it were, a certain symmetry of these. Thus too, in music, concord does not consist in expelling the sharp and the flat; but when these are co-harmonized, then concord is produced, and dissonance is exterminated. In a similar manner, the hot and the cold, the moist and the dry, being harmoniously mingled together, health is produced, and disease destroyed.

But when anger, and desire are co-harmonized, the vices and the [other] passions are extirpated, and the virtues and manners are ingenerated. Deliberate choice however, in beautiful conduct, is the greatest peculiarity of the virtue of manners. For it is possible to use reason and power without virtue; but it is not possible to use deliberate choice without it. For deliberate choice indicates the dignity of manners. Hence also, the reasoning power subduing by force anger and desire, produces continence and endurance. And again, when the reasoning power is violently dethroned by the irrational parts, then incontinence and effeminacy are produced. Such dispositions however, of the soul as these, are half-perfect virtues, and half-perfect vices. For the reasoning power of the soul is [according to its natural subsistence] in a healthy, but the irrational parts are in a diseased condition.

And so far indeed, as anger and desire are governed and led by the rational part of the soul, continence and endurance become virtues; but so far as this is effected by violence, and not voluntarily, they become vices. For it is necessary that virtue should perform such things as are fit, not with pain, but with pleasure. Again, so far as anger and desire govern the reasoning power, effeminacy and incontinence are produced, which are certain vices. But so far, as they gratify the passions with pain, knowing that they are erroneous, in consequence of the eye of the soul being sane,—so far as this is the case, they are not vices. Hence, it is evident that virtue must necessarily perform what is fit voluntarily; that which is involuntary indeed, not being without pain and fear; and that which is voluntary, not subsisting without pleasure and delight.

(1) The order of the soul subsists in such a way, that one part of it is the reasoning power, another is anger, and another is desire. And the reasoning power, indeed, has dominion over knowledge; anger over impetus; and desire intrepidly rules over the appetitions of the soul. When therefore these three parts pass into one, and exhibit one appropriate composition, then virtue and concord are produced in the soul. But when they are divulsed from each other by sedition, then vice and discord are produced in the soul. It is necessary, however, that virtue should have these three things, viz. reason, power, and deliberate choice. The virtue, therefore, of the reasoning power of the soul is prudence; for it is a habit of judging and contemplating.

But the virtue of the irascible part, is fortitude; for it is a habit of resisting, and enduring things of a dreadful nature. And the virtue of the epithymetic or appetitive part is temperance; for it is a moderation and detention of the pleasures which arise through the body. But the virtue of the whole soul is justice. For men indeed become bad, either through vice, or through incontinence, or through a natural ferocity. But they injure each other, either through gain, or through pleasure, or through ambition. Vice, therefore, more appropriately belongs to the reasoning part of the soul. For prudence indeed is similar to art; but vice to pernicious art. For it invents contrivances for the purpose of acting unjustly.

But incontinence rather pertains to the appetitive part of the soul. For continence consists in subduing, and incontinence in not subduing pleasures. And ferocity pertains to the irascible part of the soul. For when some one, through acting ill from desire, is gratified not as a man should be, but as a wild beast, then a thing of this kind is denominated ferocity. The effects also of these dispositions are consequent to the things for the sake of which they are performed. For avarice is consequent to vice; but vice is consequent to the reasoning part of the soul. And ambition, indeed, follows from the irascible part; and this becoming excessive, generates ferocity. Again, pleasure pertains to the appetitive part; but this being sought after more vehemently, generates incontinence. Hence, since the acting unjustly is produced from so many causes, it is evident that acting justly is effected through an equal number of causes. For virtue, indeed, is naturally beneficent and profitable; but vice is productive of evil, and is noxious.

(429) about the nature of things to be feared and not to be feared in which our legislator educated them; and this is what you term courage. I should like to hear what you are saying once more, for I do not think that I perfectly understand you. I mean that courage is a kind of salvation. Salvation of what? Of the opinion respecting things to be feared, what they are and of what nature, which the law implants through education; and I mean by the words ‘under all circumstances’ to intimate that in pleasure or in pain, or under the influence of desire or fear, a man preserves, and does not lose this opinion. Shall I give you an illustration? If you please. You know, I said, that dyers, when they want to dye wool for making the true sea-purple, begin by selecting their white colour first; this they prepare and dress with much care and pains, in order that the white ground may take the purple hue in full perfection. The dyeing then proceeds; and whatever is dyed in this manner becomes a fast colour, and no washing either with lyes or without them can take away the bloom. But, when the ground has not been duly prepared, you will have noticed how poor is the look either of purple or of any other colour. Yes, he said; I know that they have a washed-out and ridiculous appearance. Then now, I said, you will understand what our object was

(590) And this is clearly seen to be the intention of the law, which is the ally of the whole city; and is seen also in the authority which we exercise over children, and the refusal to let them be free until we have established in them a principle analogous to the constitution of a state, and by cultivation of this higher element have set up in their hearts a guardian and ruler like our own, and when this is done they may go their ways. Yes, he said, the purpose of the law is manifest. From what point of view, then, and on what ground can we say that a man is profited by injustice or intemperance or other baseness, which will make him a worse man, even though he acquire money or power by his wickedness? From no point of view at all. What shall he profit, if his injustice be undetected and unpunished? He who is undetected only gets worse, whereas he who is detected and punished has the brutal part of his nature silenced and humanized; the gentler element in him is liberated, and his whole soul is perfected and ennobled by the acquirement of justice and temperance and wisdom, more than the body ever is by receiving gifts of beauty, strength and health, in proportion as the soul is more honourable than the body. Certainly, he said.

(5) Universally therefore, virtue is a certain co-adaptation of the irrational parts of the soul to the rational part. Virtue however, is produced through pleasure and pain receiving the boundary of that which is fit. For true virtue is nothing else than the habit of that which is fit. But the fit, or the decorous, is that which ought to be; and the unfit, or indecorous, is that which ought not to be. Of the indecorous however, there are two species, viz. excess and defect. And excess indeed, is more than is fit; but defect is less than is fit. But since the fit is that which ought to be, it is both a summit and a middle. It is a summit indeed, because it neither requires ablation, nor addition; but it is a middle, because it subsists between excess and defect.

The fit, however, and the unfit, are to each other as the equal and the unequal that which is arranged, and that which is without arrangement; and both the two former and the two latter are finite and infinite. On this account, the parts of the unequal are referred to the middle, but not to each other. For the angle is called obtuse which is greater than a right angle; but that is called acute, which is less than a right angle. The right line also [in a circle] is greater, which surpasses that which is drawn from the center. And the day is longer indeed, which exceeds that of the equinox. Diseases, likewise, of the body are generated, through the body becoming more hot or more cold [than is proper].

For that which is more hot [than is fit] exceeds moderation; and that which is more cold [than is fit] is below mediocrity. The soul also, and such things as pertain to it, have this disposition and analogy. For audacity indeed, is an excess of the decorous in the endurance of things of a dreadful nature; but timidity is a deficiency of the, decorous. And prodigality is an excess of what is fit in the expenditure of money; but illiberality is a deficiency in this. And rage indeed, is an excess of the decorous in the impulse of the irascible part of the soul; but insensibility is a deficiency of this. The same reasoning likewise applies to the opposition of the other dispositions of the soul.

It is necessary however, that virtue, since it is a habit of the decorous, and a medium of the passions, should neither be [wholly] impassive, nor immoderately passive. For impassivity indeed, causes the soul to be unimpelled, and to be without an enthusiastic tendency to the beautiful in conduct; but immoderate passivity causes it to be full of perturbation, and inconsiderate. It is necessary therefore, that passion should so present itself to the view, in virtue, as shadow and outline in a picture. For the animated and the delicate, and that which imitates the truth, in conjunction with goodness of colors, are especially effected in a picture through these [i. e. through shadow and outline]. But the passions of the soul are animated by the natural incitation and enthusiasm of virtue.

For virtue is generated from the passions, and when generated, again subsists together with them; just as that which is well harmonized consists of the sharp and the flat, that which is well mingled consists of the hot and the cold, and that which is in equilibrium derives its equality of weight from the heavy and the light. It is not therefore necessary to take away the passions of the soul; for neither would this be profitable; but it is requisite that they should be co-harmonized with the rational part, in conjunction with fitness and mediocrity.
