Plutarch De Virtute Morali 4

[4] As for those who wonder how it should come to pass, that that which is irrational in itself should yet become obsequious to the dictates of right reason, they seem to me not to have duly considered the force and power of reason, how great and extensive it is, and how far it is able to carry and extend its authority and command, not so much by harsh and arbitrary methods, as by soft and gentle means, which persuade more and gain obedience sooner than all the severities and violences in the world. For even the spirits, the nerves, bones, and other parts of the body are destitute of reason; but yet no sooner do they feel the least motion of the will, reason shaking (as it were), though never so gently, the reins, but all of them observe their proper order, agree together, and pay a ready obedience. As, for instance, the feet, if the impulse of the mind be to run, immediately betake themselves to their office; or if the motion of the will be for the throwing or lifting up of any thing, the hands in a moment fall to their business. And this sympathy or consent of the brutal faculties to right reason, and the ready conformity of them thereto, Homer has most admirably expressed in these verses: Under such perfect subjection to his reason and judgment had he even his spirits, his blood, and his tears. A most evident proof of this matter we have also from hence, that our natural desires and motions are as soon repressed and. quieted as we know we are either by reason or law forbidden to approach the fair ones we at the first view had so great a passion for; a thing which most commonly happens to those who are apt to fall in love at sight with beautiful women, without knowing or examining who they are; for no sooner do they afterwards find their error, by discovering the person with whose charms they were before captivated to be a sister or a daughter, but their flame is presently extinguished by the interposition of reason. And flesh and blood are immediately brought into order, and become obedient to the judgment. It often falls out likewise that, after we have eaten some kinds of meat or fish finely dressed, and by that means artificially disguised, with great pleasure and a very good stomach, at the first moment we understand they were either unclean, or unlawful and forbidden, our judgment being thereby shocked, we feel not only remorse and trouble in our mind, but the conceit reaches farther, and our whole frame is disordered by the nauseous qualms and vomitings thereby occasioned. I fear I should be thought on purpose to hunt after too far-fetched and youthful instances to insert in this discourse, if I should take notice of the lute, the harp, the pipe and flute, and such like musical instruments invented by art, and adapted to the raising or allaying of human passions; which, though they are void of life and sense, do yet most readily accommodate themselves to the judgment, to our passions and our manners, either indulging our melancholy, increasing our mirth, or feeding our wantonness, as we happen at that time to be disposed. And therefore it is reported of Zeno himself, that, going one day to the theatre to hear Amoebeus sing to the lute, he called to his scholars, Come, says he, let us go and learn what harmony and music the guts and sinews of beasts, nay even wood and bones are capable of, by the help of numbers, proportion, and order.

But to let these things pass, I would gladly know of them, whether, when they see domestic animals (as dogs, horses, or birds) by use, feeding, and teaching brought to so high a degree of perfection as that they shall utter articulately some senseful words, and by their motions, gestures, and all their actions, shall approve themselves governable, and become useful to us; and when also they find Achilles in Homer encouraging horses, as well as men, to battle;—whether, I say, after all this, they can yet make any wonder or doubt, whether those faculties of the mind to which we owe our anger, our desires, our joys, and our sorrows, be of such a nature that they are capable of being obedient to reason, and so affected by it as to consent and become entirely subject to it; considering especially that these faculties are not seated without us, or separated from us, or formed by any thing which is not in us, or hammered out by force and violence, but, as they have by nature their entire dependence upon the soul, so they are ever conversant and bred up with it, and also receive their final complement and perfection from use, custom, and practice. For this reason the Greeks very properly call manners ἦθος, custom; for they are nothing else, in short, but certain qualities of the irrational and brutal part of the mind, and hence by them are so named, in that this brutal and irrational part of the mind being formed and moulded by right reason, by long custom and use (which they call ἔθος), has these qualities or differences stamped upon it. Not that reason so much as attempts to eradicate our passions and affections, which is neither possible nor expedient, but only to keep them within due bounds, reduce them into good order, and so direct them to a good end; and thus to generate moral virtue, consisting not in a kind of insensibility, or total freedom from passions, but in the well-ordering our passions and keeping them within measure, which she effects by wisdom and prudence, bringing the faculties of that part of the soul where our affections and appetite are seated to a good habit. For these three things are commonly held to be in the soul, namely, a faculty or aptitude, passion, and habit. This aptitude or faculty then is the principle or very matter of passions; as for example, the power or aptitude to be angry, to be ashamed, to be confident and bold, or the like; passion is the actual exercise of that aptitude or faculty, as anger, shame, confidence, or boldness; and habit is the strength, firmness, and establishment of the disposition or faculty in the irrational part of the soul, gotten by continual use and custom, and which, according as the passions are well or ill governed by reason, becomes either virtue or vice.
