From Theages, in his Treatise “On the Virtues”:
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.
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,1 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.
From Metopus, in his Treatise “Concerning Virtue”:
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 irrational2 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.
The species however, and the parts of it, may be surveyed as follows: Since there are two parts of the soul, the rational and the irrational; the latter is divided into the irascible and appetitive. 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. And of this, that which is as it were adapted to defend us, and revenge incidental molestations, is denominated the irascible part; but that which is as it were orectic of, and desires to preserve the proper constitution of the body, is the appetitive part. It is evident therefore, that the multitude of the virtues, their differences, and their peculiarities, follow conformably to these parts of the soul.
From Clinias:
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,3 are denominated skilful and intelligent; but such as have the ethical and pre-elective part of it, are denominated useful and equitable.4 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].
From Theages, in his Treatise “On the Virtues”:
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 nature5 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.
Moreover, the arrangement of virtue according to right reason, and the transgression of it contrary to right reason, produce [in the former case] a tendency to the decorous as the final mark, and [in the latter] the frustration of it. The decorous however, is that which ought to be. But this does not require either addition or ablation; since it is that which it is requisite to be. But of the indecorous there are two species; one of which is excess, and the other defect. And excess indeed, is more, but deficiency is less, than is decorous. Virtue also, is a certain habit of the decorous. Hence it is directly, both a summit and a medium. For thus, things that are decorous are both media and summits. They are media indeed, because they fall between excess and deficiency; but they are summits, because they do not require either addition or ablation. For they are the very things themselves which they ought to be.
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.
By division also it will at the same time be found that this is the case. For knowledge and the perception of things, are the province of the rational part of the soul; but power pertains to the irrational part. For not to be able to resist pain, or to vanquish pleasure, is the peculiarity of the irrational part of the soul. But deliberate choice subsists in both these, viz. in the rational, and also in the irrational part. For it consists of dianoia and appetite; of which, dianoia indeed, pertains to the rational, but appetite to the irrational part. Hence every virtue consists in a co-adaptation of the parts of the soul; and both will and deliberate choice, entirely subsist in virtue.
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.6 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.
1. i.e. In the etherial vehicle of the soul, which when the soul energizes intellectually is spherical, and is moved circularly. This vehicle also is αὐγοειδής, or luciform, throughout diaphanous, and of a star-like nature. Hence Marcus Antoninus beautifully observes:
σφᾶιρᾰ ψυχῆς αὐτοειδής, (lege αὐγοειδής) ὄταν μήτε ἐκτείνηται ἐπι τι, μήτε ἔσω συντρέχῃ μήτε συνιζάνῃ, ἀλλά φῶτι λαμπήται, ῳ τὴν ἀλήθειαν ὄρᾳ τὴν πάντων, καὶ τὴν ἐν αὐτῃ. Lib. II.
i.e. The sphere of the soul is then luciform, when the soul is neither extended to anything [external] nor inwardly concurs with it, nor is depressed by it, but is illuminated with a light by which she sees the truth of all things, and the truth that is in herself.”
2. M. Meibomius observes, that Canter did not see that λογιστικω should be written in this place for ἄλογω. Canter however was right in retaining ἀλογω. For the dianoetic is the same with the logistic part of the soul; and it is evident that a part of the soul different from the dianoetic is here intended to be signified. Besides, as Aristotle shows in his Nicomachean Ethics, when the irrational becomes obedient to the rational part of the soul, the former then prohibits and vanquishes base appetites in conjunction with the latter.
3. viz. Such as have the theoretic virtues.
4. i.e. Such as have the ethical and political virtues.
5. The original is, ἁ δὲ δύναμις, οἱον ἀλκά τις τω σκάνεος ᾁ ὑφιστάμὲθα, καὶ εμμένομες τοις πράγμασιν. This sentence in its present state is certainly unintelligible. For σκάνεος therefore, I read φύσεως, and then the sense will be as in the above translation. The version of Canter is certainly absurd; for it is “Facultas tanquam robur et causæ, quo ferimus, et in rebus permanemus.” And Gale, as usual, takes no notice of the absurdity.
6. viz. The equal and that which is arranged, belong to the order of bound, and the unequal and that which is without arrangement, to the order of infinity. And bound and infinity are the two great principles of things after the ineffable cause of all. See the third book of my translation of Proclus, On the Theology of Plato.
