Indeed, of two good things, of which the one is the end and the other belongs to the end, none is ignorant that the end is the greater and perfecter good. Chrysippus also acknowledges this difference, as is manifest from his Third Book of Good Things. For he dissents from those who make science the end, and sets it down.... In his Treatise of Justice, however, he does not think that justice can be preserved, if any one makes pleasure to be the end; but allows it may, if pleasure is not said to be the end, but simply a good. Nor do I think that you need now to hear me repeat his words, since his Third Book of Justice is everywhere to be had. When, therefore, O my friend, they elsewhere say that no one good is greater or less than another, and that what is not the end is equal to the end, they contradict not only the common conceptions, but even their own words. Again, if of two evils, the one when it is present renders us worse, and the other hurts us but renders us not worse, it is against reason not to say that the evil which by its presence renders us worse is greater than that which hurts us but renders us not worse. Now Chrysippus indeed confesses, that there are some fears and sorrows and errors which hurt us, but render us not worse. Read his First Book of Justice against Plato; for in respect of other things, it is worth the while to note the babbling of the man in that place, expounding indifferently all matters and doctrines, as well proper to his own sect as foreign to it.
It is likewise against common sense when he says that there may be two ends or scopes proposed of life, and that all the things we do are not to be referred to one; and yet this is more against common sense, to say that there is an end, and yet that every action is to be referred to another. Nevertheless they must of necessity endure one of these. For if those things which are first according to Nature are not eligible for themselves, but the choice and taking of them agreeably to reason is, and if every one therefore does all his actions for the acquiring the first things according to Nature, then all things which are done must have their reference to this, that the principal things according to Nature may be obtained. But they think that they who aim and aspire to get these things do not have the things themselves as the end, but that to which they must make reference, namely, the choice and not the things. For the end indeed is to choose and receive these things prudently. But the things themselves and the enjoying of them are not the end, but the material ground, having its value only from the choice. For it is my opinion that they both use and write this very expression, to show the difference.
LAMPRIAS. You have exactly related both what they say and in what manner they deliver it.
DIADUMENUS. But observe how it fares with them, as with those that endeavor to leap over their own shadow; for they do not leave behind, but always carry along with them in their speech some absurdity most remote from common sense. For as, if any one should say that he who shoots does all he can, not that he may hit the mark, but that he may do all he can, such a one would rightly be esteemed to speak enigmatically and prodigiously; so these doting dreamers, who contend that the obtaining of natural things is not the end of aiming after natural things, but the taking and choosing them is, and that the desire and endeavor after health is not in every one terminated in the enjoyment of health, but on the contrary, the enjoyment of health is referred to the desire and endeavor after it, and that certain walkings and contentions of speech and suffering incisions and taking of medicines, so they are done by reason, are the end of health, and not health of them, they, I say, trifle like to those who say, Let us sup, that we may offer sacrifice, that we may bathe. But this rather changes order and custom, and all things which these men say carry with them the total subversion and confusion of affairs. Thus, we do not desire to take a walk in fit time that we may digest our meat; but we digest our meat that we may take a walk in fit time. Has Nature also made health for the sake of hellebore, instead of producing hellebore for the sake of health? For what is wanting to bring them to the highest degree of speaking paradoxes, but the saying of such things? What difference is there between him who says that health was made for the sake of medicines and not medicines for the sake of health, and him who makes the choice of medicines and their composition and use more desirable than health itself?—or rather who esteems health not at all desirable, but placing the end in the negotiation about these things, prefers desire to enjoyment, and not enjoyment to desire? For to desire, forsooth (they affirm), is joined the proceeding wisely and discreetly. It is true indeed, we will say, if respect be had to the end, that is, the enjoyment and possession of the things it pursues; but otherwise, it is wholly void of reason, if it does all things for the obtaining of that the enjoyment of which is neither honorable nor happy.
Now, since we are fallen upon this discourse, anything may rather be said to agree with common sense, than that those who have neither received nor have any conception of good do nevertheless desire and pursue it. For you see how Chrysippus drives Ariston into this difficulty, that he should understand an indifference in things inclining neither to good nor to bad, before either good or bad is itself understood; for so indifference will appear to have subsisted even before itself, if the understanding of it cannot be perceived unless good be first understood, while the good is nothing else than this very indifference. Understand now and consider this indifference which the Stoa refutes and calls consent, whence and in what manner it gives us the knowledge of good. For if without good the indifference to that which is not good cannot be understood, much less does the knowing of good things give any intelligence of itself to those who had not before some notion of the good. But as there can be no knowledge of the art of things wholesome and unwholesome in those who have not first some knowledge of the things themselves; so they cannot conceive any notion of the science of good and evil who have not some fore-knowledge of good and evil.
LAMPRIAS. What then is good? DIADUMENUS. Nothing but prudence. LAMPRIAS. And what is prudence? DIADUMENUS. Nothing but the science of good.
LAMPRIAS. There is much then of "Jupiter's Corinth" (that is, much begging the question) admitted into their reasoning. For I would have you let alone the saying about the turning of the pestle, lest you should seem to mock them; although an accident like to that has insinuated itself into their discourse. For it seems that, to the understanding of good, one has need to understand prudence, and to seek for prudence in the understanding of good, being forced always to pursue the one by the other, and thus failing of both; since to the understanding of each we have need of that which cannot be known without the other be first understood.
DIADUMENUS. But there is yet another way, by which you may perceive not only the perversion but the eversion of their discourse, and the reduction of it entirely to nothing. They hold the essence of good to be the reasonable election of things according to Nature. Now the election is not reasonable which is not directed to some end, as has been said before. What, then, is this end? Nothing else, say they, but to reason rightly in the election of things according to Nature. First, then, the conception of good is lost and gone. For to reason rightly in election is an operation proceeding from an habit of right reasoning, and therefore being constrained to get this from the end; and the end not without this, we fail of understanding either of them. Besides, which is more, this reasonable election ought strictly to be a choice of things good and useful, and cooperating to the end; for how can it be reasonable to choose things which are neither convenient nor honorable nor at all eligible? For be it, as they say, a reasonable election of things having a fitness for the causing felicity; see then to what a beautiful and solemn conclusion their discourse brings them. For the end is (it seems), according to them, to reason rightly in the choice of things which are useful in causing us to reason rightly.
LAMPRIAS. When I hear these words, my friend, what is laid down seems to me strangely extravagant; and I farther want to know how this happens.
DIADUMENUS. You must then be more attentive; for it is not for every one to understand this riddle. Hear therefore and answer. Is not the end, according to them, to reason rightly in the election of things according to Nature?
