Pleasure's False Crown
Aristotle
Nicomachean Ethics

Aristotle argues that certain excellences like sight and knowledge are inherently valuable regardless of the pleasure they produce, proving pleasure is not the sole Chief Good.

...ent 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. Chapter III. Now what it is, and how characterised, will be more plain if we take up the subject afresh. An act of Sight is thought to be complete at any moment; that is to say, it lacks nothing the accession of which subsequently will complete its whole nature. Well, Pleasure resembles this: because it is a whole, as one may say; and one could not at any moment of time take a Pleasure whose whole...

Pleasure vs Good

This excerpt directly supports the parent's thesis by enumerating philosophical positions that deny pleasure as the chief good, explicitly stating that 'the Chief Good cannot possibly be Pleasure.' It extends the parent's argument by categorizing different views on pleasure's relation to the good.

...ce Philosopher, since he it is who has to fix the Master-End which is to guide us in dominating any object absolutely evil or good. But we may say more: an enquiry into their nature is absolutely necessary. First, because we maintained that Moral Virtue and Moral Vice are both concerned with Pains and Pleasures: next, because the greater part of mankind assert that Happiness must include Pleasure (which by the way accounts for the word they use, μακάριος; χαίρειν being the root of that word).
Now some hold that no one Pleasure is good, either in itself or as a matter of result, because Good and Pleasure are not identical. Others that some Pleasures are good but the greater number bad. There is yet a third view; granting that every Pleasure is good, still the Chief Good cannot possibly be Pleasure. In support of the first opinion (that Pleasure is utterly not-good) it is urged that: 1. Every Pleasure is a sensible process towards a complete state; but no such process is akin to the end to be attained: e.g. no process of building to the completed house.
2. The man of Perfected Self-Mastery avoids Pleasures. 3. The man of Practical Wisdom aims at avoiding Pain, not at attaining Pleasure. 4. Pleasures are an impediment to thought, and the more so the more keenly they are felt. An obvious instance will readily occur. 5. Pleasure cannot be referred to any Art: and yet every good is the result of some Art. 6. Children and brutes pursue Pleasures. In support of the second (that not all Pleasures are good), That there are some base and matter o...

True vs Apparent Good

This reply shifts the discussion from whether pleasure is the chief good to a more fundamental inquiry into what constitutes 'true good.' It contrasts virtues (like prudence and justice) with commonly esteemed but vulgar goods such as wealth and pleasure, thereby reframing the value axis.

...ainst thine own proper God, and inward spirit. For it is not in any man's power to constrain thee to transgress against him. XI. What is the use that now at this present I make of my soul? Thus from time to time and upon all occasions thou must put this question to thyself; what is now that part of mine which they call the rational mistress part, employed about? Whose soul do I now properly possess? a child's? or a youth's? a woman's? or a tyrant's? some brute, or some wild beast's soul? XII.
What those things are in themselves, which by the greatest part are esteemed good, thou mayest gather even from this. For if a man shall hear things mentioned as good, which are really good indeed, such as are prudence, temperance, justice, fortitude, after so much heard and conceived, he cannot endure to hear of any more, for the word good is properly spoken of them. But as for those which by the vulgar are esteemed good, if he shall hear them mentioned as good, he doth hearken for more. He is well contented to hear, that what is spoken by the comedian, is but familiarly and popularly spoken,...
XIII. All that I consist of, is either form or matter. No corruption can reduce either of these unto nothing: for neither did I of nothing become a subsistent creature. Every part of mine then will by mutation be disposed into a certain part of the whole world, and that in time into another part; and so in infinitum; by which kind of mutation, I also became what I am, and so did they that begot me, and they before them, and so upwards in infinitum. For so we may be allowed to speak, though...

Reason's Sovereign Good

This candidate questions whether human reason can definitively settle the question of the sovereign good, listing a variety of conflicting opinions and suggesting the issue may be beyond reason's capacity. It introduces epistemic uncertainty about achieving certainty on such matters.

...very thing we least understand. Man is to himself the most wonderful object in nature; for he cannot conceive what the body is, still less what the mind is, and least of all how a body should be united to a mind. This is the consummation of his difficulties, and yet it is his very being. Modus quo corporibus adhærent spiritus comprehendi ab hominibus non potest, et hoc tamen homo est.[35] Finally, to complete the proof of our weakness, I shall conclude with these two considerations.... 73
[But perhaps this subject goes beyond the capacity of reason. Let us therefore examine her solutions to problems within her powers. If there be anything to which her own interest must have made her apply herself most seriously, it is the inquiry into her own sovereign good. Let us see, then, wherein these strong and clear-sighted souls have placed it, and whether they agree. One says that the sovereign good consists in virtue, another in pleasure, another in the knowledge of nature, another in truth, Felix qui potuit rerum cognoscere causas, another in total ignorance, another in indolence,...
We are well satisfied. To transpose after the laws to the following title. We must see if this fine philosophy have gained nothing certain from so long and so intent study; perhaps at least the soul will know itself. Let us hear the rulers of the world on this subject. What have they thought of her substance? 394.[38] Have they been more fortunate in locating her? 395.[39] What have they found out about her origin, duration, and departure? 399.[40] Is then the soul too noble a subject for...

Habit's Pleasure Test

This excerpt provides practical guidance on moral development by proposing a test for virtuous habits: one should assess the pleasure or pain that follows actions. It advises that the truly virtuous person not only acts rightly but feels pleasure in doing so, offering a method to cultivate alignment between pleasure and excellence.

...doing plenty of work, and the man who has attained strength is best able to do these: and so it is with the Virtues, for not only do we by abstaining from pleasures come to be perfected in Self-Mastery, but when we have come to be so we can best abstain from them: similarly too with Courage: for it is by accustoming ourselves to despise objects of fear and stand up against them that we come to be brave; and after we have come to be so we shall be best able to stand up against such objects. And
For a test of the formation of the habits we must take the pleasure or pain which succeeds the acts; for he is perfected in Self-Mastery who not only abstains from the bodily pleasures but is glad to do so; whereas he who abstains but is sorry to do it has not Self-Mastery: he again is brave who stands up against danger, either with positive pleasure or at least without any pain; whereas he who does it with pain is not brave. For Moral Virtue has for its object-matter pleasures and pains, because by reason of pleasure we do what is bad, and by reason of pain decline doing what is right (for wh...
Again: since Virtues have to do with actions and feelings, and on every feeling and every action pleasure and pain follow, here again is another proof that Virtue has for its object-matter pleasure and pain. The same is shown also by the fact that punishments are effected through the instrumentality of these; because they are of the nature of remedies, and it is the nature of remedies to be the contraries of the ills they cure. Again, to quote what we said before: every habit of the Soul by its...
