Of Moral Virtue by Plutarch

1. My design in this essay is to treat of that virtue which is called and accounted moral, and is chiefly distinguished from the contemplative, in its having for the matter thereof the passions of the mind, and for its form, right reason; and herein to consider the nature of it and how it subsists, and whether that part of the soul wherein it resides be endowed with reason of its own, inherent in itself, or whether it participates of that which is foreign; and if the latter, whether it does this after the manner of those things which are mingled with what is better than themselves, or whether, as being distinct itself but yet under the dominion and superintendency of another, it may be said to partake of the power of the predominant faculty. For that it is possible for virtue to exist and continue altogether independent of matter, and free from all mixture, I take to be most manifest. But in the first place I conceive it may be very useful briefly to run over the opinions of other philosophers, not so much for the vanity of giving an historical account thereof, as that, they being premised, ours may thence receive the greater light and be more firmly established.

2. To begin then with Menedemus of Eretria, he took away both the number and the differences of virtue, by asserting it to be but one, although distinguished by several names; holding that, in the same manner as a mortal and a man are all one, so what we call temperance, fortitude, and justice are but one and the same thing. As for Ariston of Chios, he likewise made virtue to be but one in substance, and called it sanity, which, as it had respect to this or that, was to be variously multiplied and distinguished; just after the same manner as if any one should call our sight, when applied to any white object, by the name of white-look; when to one that is black, by the name of black-look; and so in other matters. For according to him, virtue, when it considers such things as we ought to do or not to do, is called prudence; when it moderates our desires, and prescribes the measure and season for our pleasures, temperance; and when it governs the commerce and mutual contracts of mankind, justice; -in the same manner, for instance, as a knife is one and the same knife still, notwithstanding sometimes it cuts one thing, sometimes another, and just as fire does operate upon different matter, and yet retain the very same nature. Unto which opinion it seems also as if Zeno the Citian did in some measure incline; he defining prudence, while it distributes to every man his own, to be justice; when it teaches what we are to choose and what to reject or avoid, temperance; and with respect to what is to be borne or suffered, fortitude. But it is to be observed, that they who take upon them the defence of Zeno's notions do suppose him to mean science by what he calls prudence. But then Chrysippus, whilst he imagined from every distinct quality a several and peculiar virtue to be formed, before he was aware, raised (as Plato hath it) a whole swarm of virtues never before known or used among the philosophers. For as from brave he derived bravery; from mild, mildness; and from just, justice; so from pleasant he fetched pleasantness; from good, goodness; from grand, grandeur; and from honest, honesty; placing these and all kind of dexterous application of discourse, all kind of facetiousness of conversation, and all witty turns of expression in the number of virtues, thereby over-running philosophy, which requires nothing less, with a multitude of uncouth, absurd, and barbarous terms.

3. However, all these do commonly agree in this one thing, in supposing virtue to be a certain disposition and faculty of the governing and directive part of the soul, of which reason is the cause; or rather to be reason itself, when it consents to what it ought, and is firm and immutable. And they do likewise think, that that part of the soul which is the seat of the passions, and is called brutal or irrational, is not at all distinct by any physical difference from that which is rational; but that this part of the soul (which they call rational and directive), being wholly turned about and changed by its affections and by those several alterations which are wrought in it with respect either to habit or disposition, becometh either vice or virtue, without having any thing in itself that is really brutal or irrational, but is then called brutal or irrational, when by the over-ruling and prevailing violence of our appetites it is hurried on to something absurd and vicious, against the judgment of reason. For passion, according to them, is nothing else but depraved and intemperate reason, that through a perverse and vicious judgment is grown over-vehement and headstrong.
