Now Eudoxus thought Pleasure to be the Chief Good because he saw all, rational and irrational alike, aiming at it: and he argued that, since in all what was the object of choice must be good and what most so the best, the fact of all being drawn to the same thing proved this thing to be the best for all: “For each,” he said, “finds what is good for itself just as it does its proper nourishment, and so that which is good for all, and the object of the aim of all, is their Chief Good.”
(And his theories were received, not so much for their own sake, as because of his excellent moral character; for he was thought to be eminently possessed of perfect self-mastery, and therefore it was not thought that he said these things because he was a lover of Pleasure but that he really was so convinced.)
And he thought his position was not less proved by the argument from the contrary: that is, since Pain was in itself an object of avoidance to all the contrary must be in like manner an object of choice.
Again he urged that that is most choice-worthy which we choose, not by reason of, or with a view to, anything further; and that Pleasure is confessedly of this kind because no one ever goes on to ask to what purpose he is pleased, feeling that Pleasure is in itself choice-worthy.
Again, that when added to any other good it makes it more choice-worthy; as, for instance, to actions of justice, or perfected self-mastery; and good can only be increased by itself.
However, this argument at least seems to prove only that it belongs to the class of goods, and not that it does so more than anything else: for every good is more choicewortby in combination with some other than when taken quite alone. In fact, it is by just such an argument that Plato proves that Pleasure is not the Chief Good: [3] “For,” says he, “the life of Pleasure is more choice-worthy in combination with Practical Wisdom than apart from it; but, if the compound better then simple Pleasure cannot be the Chief Good; because the very Chief Good cannot by any addition become choice-worthy than it is already:” and it is obvious that nothing else can be the Chief Good, which by combination with any of the things in themselves good comes to be more choice-worthy.
What is there then of such a nature? (meaning, of course, whereof we can partake; because that which we are in search of must be such).
As for those who object that “what all aim at is not necessarily good,” I confess I cannot see much in what they say, because what all think we say is. And he who would cut away this ground from under us will not bring forward things more dependable: because if the argument had rested on the desires of irrational creatures there might have been something in what he says, but, since the rational also desire Pleasure, how can his objection be allowed any weight? and it may be that, even in the lower animals, there is some natural good principle above themselves which aims at the good peculiar to them.
Nor does that seem to be sound which is urged respecting the argument from the contrary: I mean, some people say “it does not follow that Pleasure must be good because Pain is evil, since evil may be opposed to evil, and both evil and good to what is indifferent:” now what they say is right enough in itself but does not hold in the present instance. If both Pleasure and Pain were bad both would have been objects of avoidance; or if neither then neither would have been, at all events they must have fared alike: but now men do plainly avoid the one as bad and choose the other as good, and so there is a complete opposition.
Nor again is Pleasure therefore excluded from being good because it does not belong to the class of qualities: [4] the acts of Virtue are not qualities, neither is Happiness [yet surely both are goods].
Again, they say the Chief Good is limited but Pleasure unlimited, in that it admits of degrees.
Now if they judge this from the act of feeling Pleasure then the same thing will apply to justice and all the other virtues, [5] in respect of which clearly it is said that men are more or less of such and such characters (according to the different virtues), they are more just or more brave, or one may practise justice and self-mastery more or less.
If, on the other hand, they judge in respect of the Pleasures themselves then it may be they miss the true cause, namely that some are unmixed and others mixed: for just as health being in itself limited, admits of degrees, why should not Pleasure do so and yet be limited? in the former case we account for it by the fact that there is not the same adjustment of parts in all men, nor one and the same always in the same individual: but health, though relaxed, remains up to a certain point, and differs in degrees; and of course the same may be the case with Pleasure.
Again, assuming the Chief Good to be perfect and all Movements [6] and Generations imperfect, they try to shew that Pleasure is a Movement and a Generation.
Yet they do not seem warranted in saying even that it is a Movement: for to every Movement are thought to belong swiftness and slowness, and if not in itself, as to that of the universe, yet relatively: but to Pleasure neither of these belongs: for though one may have got quickly into the state Pleasure, as into that of anger, one cannot be in the state quickly, [7] nor relatively to the state of any other person; but we can walk or grow, and so on, quickly or slowly.
Of course it is possible to change into the state of Pleasure quickly or slowly, but to act in the state (by which, I mean, have the perception of Pleasure) quickly, is not possible.
And how can it be a Generation? because, according to notions generally held, not anything is generated from anything, but a thing resolves itself into that out of which it was generated: whereas of that of which Pleasure is a Generation Pain is a Destruction.
Again, they say that Pain is a lack of something suitable to nature and Pleasure a supply of it.
But these are affections of the body: now if Pleasure really is a supplying of somewhat suitable to nature, that must feel the Pleasure in which the supply takes place, therefore the body of course: yet this is not thought to be so: neither then is Pleasure a supplying, only a person of course will be pleased when a supply takes place just as he will be pained when he is cut short.
This notion would seem to have arisen out of the Pains and Pleasures connected with natural nourishment; because, when people have felt a lack and so have had Pain first, they, of course, are pleased with the supply of their lack.
But this is not the case with all Pleasures: those attendant on mathematical studies, for instance, are unconnected with any Pain; and of such as attend on the senses those which arise through the sense of Smell; and again, many sounds, and sights, and memories, and hopes: now of what can these be Generations? because there has been here no lack of anything to be afterwards supplied.
And to those who bring forward disgraceful Pleasures we may reply that these are not really pleasant things; for it does not follow because they are pleasant to the ill-disposed that we are to admit that they are pleasant except to them; just as we should not say that those things are really wholesome, or sweet, or bitter, which are so to the sick, or those objects really white which give that impression to people labouring under ophthalmia. [8]
Or we might say thus, that the Pleasures are choice-worthy but not as derived from these sources: just as wealth is, but not as the price of treason; or health, but not on the terms of eating anything however loathsome.
Or again, may we not say that Pleasures differ in kind? those derived from honourable objects, for instance are different from those arising from disgraceful ones; and it is not possible to experience the Pleasure of the just man without being just, or of the musical man without being musical; and so on of others.
The distinction commonly drawn between the friend and the flatterer would seem to show clearly either that Pleasure is not a good, or that there are different kinds of Pleasure: for the former is thought to have good as the object of his intercourse, the latter Pleasure only; and this last is reproached, but the former men praise as having different objects in his intercourse.
Again, no one would choose to live with a child’s intellect all his life through, though receiving the highest possible Pleasure from such objects as children receive it from; or to take Pleasure in doing any of the most disgraceful things, though sure never to be pained.
There are many things also about which we should be diligent even though they brought no Pleasure; as seeing, remembering, knowing, possessing the various Excellences; and the fact that Pleasures do follow on these naturally makes no difference, because we should certainly choose them even though no Pleasure resulted from them.
It seems then to be plain that Pleasure is not the Chief Good, nor is every kind of it choice-worthy: and that there are some choice-worthy in themselves, differing in kind, i.e. in the sources from which they are derived. Let this then suffice by way of an account of the current maxims respecting Pleasure and Pain.
