(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.

(1) It appears to me that the justice which subsists among men, may be called the mother and the nurse of the other virtues. For without this a man can neither be temperate, nor brave, nor prudent. For it is the harmony and peace, in conjunction with elegance, of the whole soul. The strength however of this virtue will become more manifest, if we direct our attention to the other habits. For they have a partial utility, and which is referred to one thing; but this is referred to whole systems, and to a multitude. In the world therefore, it conducts the whole government of things, and is providence, harmony, and Dice, by the decree of a certain genus of Gods.

But in a city it is justly called peace, and equitable legislation. And in a house, it is the concord between the husband and wife; the benevolence of the servant towards the master; and the anxious care of the master for the welfare of the servant. In the body likewise, which is the first and dearest thing to all animals, [so far as they are animals,] it is the health and intireness of all the parts. But in the soul, it is the wisdom, which among men subsists from science and justice. If therefore, this virtue thus disciplines and saves both the whole and the parts [of every thing] rendering things concordant and familiar with each other, how is it possible it should not be called by the decision of all men, the mother and the nurse of all things?

(2) Let us begin with virtue and vice in the Soul. What has really occurred when, as we say, vice is present? In speaking of extirpating evil and implanting goodness, of introducing order and beauty to replace a former ugliness, we talk in terms of real things in the Soul.

Now when we make virtue a harmony, and vice a breach of harmony, we accept an opinion approved by the ancients; and the theory helps us decidedly to our solution. For if virtue is simply a natural concordance among the phases of the Soul, and vice simply a discord, then there is no further question of any foreign presence; harmony would be the result of every distinct phase or faculty joining in, true to itself; discord would mean that not all chimed in at their best and truest. Consider, for example, the performers in a choral dance; they sing together though each one has his particular part, and sometimes one voice is heard while the others are silent; and each brings to the chorus something of his own; it is not enough that all lift their voices together; each must sing, choicely, his own part to the music set for him. Exactly so in the case of the Soul; there will be harmony when each faculty performs its appropriate part.

Yes: but this very harmony constituting the virtue of the Soul must depend upon a previous virtue, that of each several faculty within itself; and before there can be the vice of discord there must be the vice of the single parts, and these can be bad only by the actual presence of vice as they can be good only by the presence of virtue. It is true that no presence is affirmed when vice is identified with ignorance in the reasoning faculty of the Soul; ignorance is not a positive thing; but in the presence of false judgements- the main cause of vice- must it not be admitted that something positive has entered into the Soul, something perverting the reasoning faculty? So, the initiative faculty; is it not, itself, altered as one varies between timidity and boldness? And the desiring faculty, similarly, as it runs wild or accepts control?

Our teaching is that when the particular faculty is sound it performs the reasonable act of its essential nature, obeying the reasoning faculty in it which derives from the Intellectual Principle and communicates to the rest. And this following of reason is not the acceptance of an imposed shape; it is like using the eyes; the Soul sees by its act, that of looking towards reason. The faculty of sight in the performance of its act is essentially what it was when it lay latent; its act is not a change in it, but simply its entering into the relation that belongs to its essential character; it knows- that is, sees- without suffering any change: so, precisely, the reasoning phase of the Soul stands towards the Intellectual Principle; this it sees by its very essence; this vision is its knowing faculty; it takes in no stamp, no impression; all that enters it is the object of vision- possessed, once more, without possession; it possesses by the fact of knowing but "without possession" in the sense that there is no incorporation of anything left behind by the object of vision, like the impression of the seal on sealing-wax.

And note that we do not appeal to stored-up impressions to account for memory: we think of the mind awakening its powers in such a way as to possess something not present to it.

Very good: but is it not different before and after acquiring the memory?

Be it so; but it has suffered no change- unless we are to think of the mere progress from latency to actuality as change- nothing has been introduced into the mind; it has simply achieved the Act dictated by its nature.

It is universally true that the characteristic Act of immaterial entities is performed without any change in them- otherwise they would at last be worn away- theirs is the Act of the unmoving; where act means suffering change, there is Matter: an immaterial Being would have no ground of permanence if its very Act changed it.

Thus in the case of Sight, the seeing faculty is in act but the material organ alone suffers change: judgements are similar to visual experiences.

But how explain the alternation of timidity and daring in the initiative faculty?

Timidity would come by the failure to look towards the Reason-Principle or by looking towards some inferior phase of it or by some defect in the organs of action- some lack or flaw in the bodily equipment- or by outside prevention of the natural act or by the mere absence of adequate stimulus: boldness would arise from the reverse conditions: neither implies any change, or even any experience, in the Soul.

So with the faculty of desire: what we call loose living is caused by its acting unaccompanied; it has done all of itself; the other faculties, whose business it is to make their presence felt in control and to point the right way, have lain in abeyance; the Seer in the Soul was occupied elsewhere, for, though not always at least sometimes, it has leisure for a certain degree of contemplation of other concerns.

Often, moreover, the vice of the desiring faculty will be merely some ill condition of the body, and its virtue, bodily soundness; thus there would again be no question of anything imported into the Soul.

(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 .
