(1) The virtue of man is the perfection of the nature of man. For every being becomes perfect, and arrives at the summit of excellence according to the proper nature of its virtue. Thus the virtue of a horse, is that which leads the nature of a horse to its summit. And the same reasoning is applicable to the several parts of a thing. Thus the virtue of the eyes is acuteness of vision: and this in the nature of the eyes is the summit. The virtue of the ears also, is acuteness of hearing: and this is the summit of the nature of the ears. Thus too, the virtue of the feet is swiftness: and this is the summit of the nature of the feet.

It is necessary however, that every virtue should have these three things, reason, power, and deliberate choice; reason indeed, by which it judges and contemplates; power, by which it prohibits and vanquishes; and deliberate choice, by which it loves and delights in [what is proper]. To judge therefore, and contemplate, pertain to the dianoetic part of the soul; but to prohibit and vanquish are the peculiarity of the irrational part of the soul; and to love and delight in what is proper, pertain to both the rational and irrational parts. For deliberate choice consists of dianoia [or the discursive energy of reason] and appetite. Dianoia therefore, belongs to the rational, but appetite to the irrational part of the soul. The multitude however, of all the virtues, may be perceived from the parts of the soul; and in a similar manner the generation and nature of virtue.

For of the parts of the soul, there are two that rank as the first, viz. the rational and the irrational parts. And the rational part indeed, is that by which we judge and contemplate; but the irrational part is that by which we are impelled and desire. These however, are either concordant or discordant with each other. But the contest and dissonance between them, are produced through excess and defect. It is evident therefore, that when the rational vanquishes the irrational part of the soul, endurance and continence are produced; and that when the former leads, and the latter follows, and both accord with each other, then virtue is generated. Hence, endurance and continence are generated accompanied with pain; but endurance resists pain, and continence pleasure.

Incontinence however, and effeminacy, neither resist nor vanquish [pleasure]. And on this account it happens that men fly from good through pain, but reject it through pleasure. Praise likewise, and blame, and every thing beautiful in human conduct are produced in these parts of the soul. And in short, the nature of virtue derives its subsistence after this manner.

(1) The principles of all virtue are three; knowledge, power, and deliberate choice. And knowledge indeed, is that by which we contemplate and form a judgment of things; power is as it were a certain strength of the nature from which we derive our subsistence, and is that which gives stability to our actions; and deliberate choice is as it were certain hands of the soul by which we are impelled to, and lay hold on the objects of our choice. The order of the soul also subsists as follows: One part of it is the reasoning power, another part is anger, and another is desire. And the reasoning power indeed, is that which has dominion over knowledge; anger is that which rules over the ardent impulses of the soul; and desire is that which willingly rules over appetite.

When therefore, these three pass into one, so as to exhibit one co-adaptation, then virtue and concord are produced in the soul; but when they are seditious, and divulsed from each other, then vice and discord are generated in the soul. And when the reasoning power prevails over the irrational parts of the soul, then endurance and continence are produced; endurance indeed, in the retention of pains; but continence in the abstinence from pleasures. But when the irrational parts of the soul prevail over the reasoning power, then effeminacy and incontinence are produced; effeminacy indeed, in flying from pain; but incontinence, in the being vanquished by pleasures. When however, the better part of the soul governs, but the less excellent part is governed; and the former leads, but the latter follows, and both consent, and are concordant with each other, then virtue and every good are generated in the whole soul.

When likewise the appetitive follows the reasoning part of the soul, then temperance is produced; but when this is the case with the irascible part, fortitude is produced; and when it takes place in all the parts of the soul, then justice is the result. For justice is that which separates all the vices and all the virtues of the soul from each other. And justice is a certain established order of the apt conjunction of the parts of the soul, and perfect and supreme virtue. For every good is contained in this; but the other goods of the soul cannot subsist without this. Hence justice possesses great strength both among Gods and men. For this virtue contains the bond by which the whole and the universe are held together, and also by which Gods and men are connected.

Justice therefore, is said to be Themis among the celestial, but Dice among the terrestrial Gods; and Law among men. These assertions however, are indications and symbols, that justice is the supreme virtue. Hence virtue, when it consists in contemplating and judging, is called prudence; when in sustaining things of a dreadful nature, it is denominated fortitude; when in restraining pleasure, temperance; and when in abstaining from gain, and from injuring our neighbours, justice.

(2) Since, however, of the parts of the soul, one is the leader, but the other follows, and the virtues and the vices subsist about these, and in these; it is evident that with respect to the virtues also, some are leaders, others are followers, and others, are composed from these. And the leaders, indeed, are such as prudence; but the followers are such as fortitude and temperance; and the composites from these, are such as justice. The passions, however, are the matter of virtue; for the virtues subsist about, and in these. But of the passions, one is voluntary, but another is involuntary. And the voluntary, indeed, is pleasure; but the involuntary is pain. Men also, who have the political virtues, give intension and remission to these, co-harmonizing the other parts of the soul, to that part which possesses reason.

But the boundary of this co-adaptation, is for intellect not to be prevented from accomplishing its proper work, either by indigence, or excess. For that which is less excellent, is co-arranged for the sake of that which is more excellent. Thus in the world, every part that is always passive, subsists for the sake of that which is always moved. And in the conjunction of animals, the female subsists for the sake of the male. For the latter sows, generating a soul; but the former alone imparts matter to that which is generated. In the soul however, the irrational subsists for the sake of the rational part. For anger and desire are co-arranged in subserviency to the first part of the soul; the former as a certain satellite, and guardian of the body; but the latter as a dispensator and provident curator of necessary wants.

But intellect being established in the highest summit of the body, and having a prospect in that which is on all sides splendid and transparent, investigates the wisdom of [real] beings. And this is the work of it according to nature, viz. having investigated, and obtained the possession [of truth] to follow those beings who are more excellent and more honorable than itself. For the knowledge of things divine and most honorable, is the principle, cause, and rule of human blessedness .

(2) But it is clear to every one that piety, which teaches to worship and honour, is the highest and oldest cause; and the law itself exhibits justice, and teaches wisdom, by abstinence from sensible images, and by inviting to the Maker and Father of the universe. And from this sentiment, as from a fountain, all intelligence increases. "For the sacrifices of the wicked are abomination to the Lord; but the prayers of the upright are acceptable before Him," since "righteousness is more acceptable before God than sacrifice." Such also as the following we find in Isaiah: "To what purpose to me is the multitude of your sacrifices? saith the Lord;" and the whole section. "Break every bond of wickedness; for this is the sacrifice that is acceptable to the Lord, a contrite heart that seeks its Maker." "Deceitful balances are abomination before God; but a just balance is acceptable to Him." Thence Pythagoras exhorts "not to step over the balance;" and the profession of heresies is called deceitful righteousness; and "the tongue of the unjust shall be destroyed, but the mouth of the righteous droppeth wisdom." "For they call the wise and prudent worthless." But it were tedious to adduce testimonies respecting these virtues, since the whole Scripture celebrates them. Since, then, they define manliness to be knowledge of things formidable, and not formidable, and what is intermediate; and temperance to be a state of mind which by choosing and avoiding preserves the judgments of wisdom; and conjoined with manliness is patience, which is called endurance, the knowledge of what is bearable and what is unbearable; and magnanimity is the knowledge which rises superior to circumstances. With temperance also is conjoined caution, which is avoidance in accordance with reason. And observance of the commandments, which is the innoxious keeping of them, is the attainment of a secure life. And there is no endurance without manliness, nor the exercise of self-restraint without temperance. And these virtues follow one another; and with whom are the sequences of the virtues, with him is also salvation, which is the keeping of the state of well-being. Rightly, therefore, in treating of these virtues, we shall inquire into them all; for he that has one virtue gnostically, by reason of their accompanying each other, has them all. Self-restraint is that quality which does not overstep what appears in accordance with right reason. He exercises self-restraint, who curbs the impulses that are contrary to right reason, or curbs himself so as not to indulge in desires contrary to right reason. Temperance, too, is not without manliness; since from the commandments spring both wisdom, which follows God who enjoins, and that which imitates the divine character, namely righteousness; in virtue of which, in the exercise of self-restraint, we address ourselves in purity to piety and the course of conduct thence resulting, in conformity with God; being assimilated to the Lord as far as is possible for us beings mortal in nature. And this is being just and holy with wisdom; for the Divinity needs nothing and suffers nothing; whence it is not, strictly speaking, capable of self-restraint, for it is never subjected to perturbation, over which to exercise control; while our nature, being capable of perturbation, needs self-constraint, by which disciplining itself to the need of little, it endeavours to approximate in character to the divine nature. For the good man, standing as the boundary between an immortal and a mortal nature, has few needs; having wants in consequence of his body, and his birth itself, but taught by rational self-control to want few things.

(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].

(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.

(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.

(12) Further, also, the philosophers regard the virtues as habits, dispositions, and sciences. And as knowledge (gnosis) is not born with men, but is acquired, and the acquiring of it in its elements demands application, and training, and progress; and then from incessant practice it passes into a habit; so, when perfected in the mystic habit, it abides, being infallible through love. For not only has he apprehended the first Cause, and the Cause produced by it, and is sure about them, possessing firmly firm and irrefragable and immoveable reasons; but also respecting what is good and what is evil, and respecting all production, and to speak comprehensively, respecting all about Which the Lord has spoken, he has learned, from the truth itself, the most exact truth from the foundation of the world to the end. Not preferring to the truth itself what appears plausible, or, according to Hellenic reasoning, necessary; but what has been spoken by the Lord he accepts as clear and evident, though concealed from others; and he has already received the knowledge of all things. And the oracles we possess give their utterances respecting what exists, as it is; and respecting what is future, as it shall be; and respecting what is past, as it was.

(2) Moreover, of perfect men there are two differences. For some of them are naturally perfect; but others are perfect according to life. And those indeed alone that are good, are naturally perfect. But these are such as possess virtue. For the virtue of the nature of every thing is a summit and perfection. Thus the virtue of the eye is the summit and perfection of the nature of the eye. But the virtue of man is the summit and perfection of the nature of man. Those also are perfect according to life, who are not only good, but happy. For felicity, indeed, is the perfection of human life. But human, life is a system of actions: and: felicity gives completion to the actions.

Virtue also and fortune give completion to actions; virtue, indeed, according to use; but good fortune according to prosperity. God therefore is neither good through learning virtue from any one, nor is he happy through being attended by good fortune. For he is good by nature, and happy by nature, and always was and will be, and will never cease to be, such; since he is incorruptible, and naturally good. But man is neither happy nor good by nature, but requires discipline and providential care. And in order to become good, indeed; he requires virtue; but in order to become happy, good fortune. On this account, human felicity summarily consists of these two things, viz. of praise, and the predication of beatitude.

Of praise indeed, from virtue; but of the predication of beatitude, from prosperity. It possesses virtue therefore, through a divine destiny, but prosperity through a mortal allotment. But mortal are suspended from divine concerns, and terrestrial from such as are celestial. Things subordinate, also, are suspended from such as are more excellent. And on this account, the good man who follows the Gods is happy; but he who follows mortal natures is miserable. For to him who possesses wisdom, prosperity is good and useful. It is good, indeed, through his knowledge of the use of it; but it is useful, through his co-operating with actions. It is beautiful, therefore, when prosperity is present with intellect, and when sailing as it were with a prosperous wind, actions are performed looking to virtue; just as a pilot looks to the motions of the stars. For thus, he who does this will not only follow God, but will also co-arrange human with divine good.

(585) mind and all the different kinds of virtue? Put the question in this way:—Which has a more pure being—that which is concerned with the invariable, the immortal, and the true, and is of such a nature, and is found in such natures; or that which is concerned with and found in the variable and mortal, and is itself variable and mortal? Far purer, he replied, is the being of that which is concerned with the invariable. And does the essence of the invariable partake of knowledge in the same degree as of essence? Yes, of knowledge in the same degree. And of truth in the same degree? Yes. And, conversely, that which has less of truth will also have less of essence? Necessarily. Then, in general, those kinds of things which are in the service of the body have less of truth and essence than those which are in the service of the soul? Far less. And has not the body itself less of truth and essence than the soul? Yes. What is filled with more real existence, and actually has a more real existence, is more really filled than that which is filled with less real existence and is less real? Of course. And if there be a pleasure in being filled with that which is according to nature, that which is more really filled with more real being will more really and truly enjoy true pleasure; whereas that which participates in less real being will be less truly and surely satisfied, and will participate in an illusory and less real pleasure? Unquestionably.
