LAMPRIAS. . Not for my sake, my dear friend, I beseech you; for I desire to understand, in what manner these men bring in evil things before the good, and vice before virtue. DIADUMENUS. It is indeed, sir, a thing worth knowing. They babble indeed much; but in conclusion they say that prudence, being the knowledge of good and evil, would be wholly taken away if there were no evil. For as, if there are truths, it is impossible but there must be some lies also near to them; so it stands with reason, that if there are good things, there must also be evil things. LAMPRIAS. . One of these things is not said amiss; and I think also that the other is not unapprehended by me. For I see a difference here: that which is not true must immediately be false; but that is not of necessity evil which is not good; because that between true and false there is no medium, but between good and evil there is the indifferent. Nor is it of necessity that the one must subsist with the other. For Nature may have good without having any need of evil, but only having that which is neither good nor evil. But if there is any thing to be said by you to the former reason, let us hear it. DIADUMENUS. Many things indeed are said; but at present we shall make use only of what is most necessary. In the first place, it is a folly to imagine that good and evil have their existence for the sake of prudence. For good and evil being already extant, prudence came afterwards; as the art of physic was invented, there being already things wholesome and unwholesome. For good and evil are not therefore extant that there may be prudence; but the faculty by which we judge good and evil that are already in being is named prudence. As sight is a sense distinguishing white from black; which colors were not therefore made that we might have sight, but we rather wanted sight to discern these things. Secondly, when the world shall be set on fire (as the Stoics will have it), there will then no evil be left, but all will then be prudent and wise. There is therefore prudence, though there is no evil; nor is it of necessity for evil to exist that prudence may have a being. But supposing that prudence must always be a knowledge of good and evil, what inconvenience would it be if, evil being taken away, prudence should no longer subsist; but instead of this we should have another virtue, not being the knowledge of good and evil, but of good only? So, if black should be wholly lost from among the colors, and any one should therefore contend that sight is also lost, for that there is no longer the sense of discerning black and white, what should hinder us from answering him: It is no prejudice to us, if we have not what you call sight, but in lieu of that have another sense and faculty, by which we apprehend colors that are white and not white. For I indeed think that neither our taste would be lost, if bitter things were wanting, nor our feeling, if pain were taken away, nor prudence, if evil had no being; but that these senses would remain, to apprehend things sweet and grateful and those that are not so, and prudence to be the science of things good and not good. But let those who think otherwise take the name to themselves, leaving us the thing. DIADUMENUS. Besides all this, what should hinder but there may be an understanding of evil, and an existence of good? As the Gods, I believe, enjoy health, but understand the fever and pleurisy. Since even we, who, as they say, have abundance of evils but no good, are not yet destitute of the knowledge what prudence, what goodness, and what happiness is. And this also would be wonderful, that if virtue were absent, there should be those who could teach us what it is and give us a comprehension of it, while if vice were not extant, it should be impossible to have any understanding of it. For see what these men persuade us who philosophize against the conceptions,—that by folly indeed we comprehend prudence, but prudence without folly cannot so much as comprehend folly itself. DIADUMENUS. And if Nature had absolutely stood in need of the generation of evil, yet might one or two examples of vice have been sufficient; or if you will, it might have been requisite that ten, a thousand, or ten thousand vicious men should be brought forth, and not that the multitude of vices should be so great as to exceed in number the sands of the sea, the dust of the earth, and the feathers of all the various kinds of birds in the world, and yet that there should not be so much all this while as a dream of virtue. Those who in Sparta had the charge of the public halls or eating places called Phiditia, were wont to bring forth two or three Helots drunken and full of wine, that the young men, seeing what drunkenness was, might learn to keep sobriety. But in human life there are many such examples of vice. For there is not any one sober to virtue; but we all stagger up and down, acting shamefully and living miserably. Thus does reason inebriate us, and with so much trouble and madness does it fill us, that we fall in nothing short of those dogs of whom Aesop says, that seeing certain skins swimming on the water, they endeavored to drink the sea up, but burst before they could get at them. For reason also, by which we hope to gain reputation and attain to virtue, does, ere we can reach to it, corrupt and destroy us, being before filled with abundance of heady and bitter vice;—if indeed, as these men say, they who are got even to the uppermost step have no ease, cessation, or breathing from folly and infelicity. DIADUMENUS. But let us see what manner of thing he shows vice to be who says that it was not brought forth unprofitably, and of what use and what a possession he makes it to be to those who have it, writing in his book of right actions, that a wicked man wants nothing, has need of nothing, nothing is useful to him, nothing proper, nothing fit for him. How then is vice useful, with which neither health nor abundance of riches nor advancement in virtue is profitable? Who then does not want these things, of which some are preferable and acceptable, and therefore highly useful, and others are according to Nature, as themselves term them? But (they say) no one has need of them, unless he become wise. Therefore the vicious man does not even stand in need of being made wise. Nor are men hungry and thirsty before they become wise. When thirsty, therefore, they have no need of water, nor when hungry, of bread. Be like to courteous guests, and him Who only fire and shelter asks: does this man now not need entertainment? Nor had he need of a cloak, who said, Give Hipponax a cloak, for I’m stiff with cold. But will you speak a paradox indeed, both extravagant and singular? Say then that a wise man has need of nothing, that he wants nothing, he is fortunate, he is free from want, he is self-sufficient, blessed, perfect. Now what madness is this, that he to whom nothing is wanting has need of the goods he has, but that the vicious indeed wants many things, and stands in need of nothing. For thus indeed says Chrysippus, that the vicious wants but stands not in need; removing the common notions, like chessmen, backwards and forwards. For all men think that having need precedes wanting, esteeming him who stands in need of things that are not at hand or easy to be got, to want them. For no man wants horns or wings, because no man has need of them. But we say that those want arms and money and clothes who are destitute of them, when they have occasion for them. But these men are so desirous of seeming always to say something against the common notions, that for the love of novelty they often depart from their own opinions, as they do here.
