Intellectual Pleasure's Clarity
Arthur Schopenhauer
The Wisdom of Life

The author posits that intellectual pleasures are superior to all others because they are independent of the will's painful desires and lead to the clarity of truth.

...the world can boast. The highest product of Nature is the clearest degree of consciousness, in which the world mirrors itself more plainly and completely than anywhere else. A man endowed with this form of intelligence is in possession of what is noblest and best on earth; and accordingly, he has a source of pleasure in comparison with which all others are small. From his surroundings he asks nothing but leisure for the free enjoyment of what he has got, time, as it were, to polish his diamond.
All other pleasures that are not of the intellect are of a lower kind; for they are, one and all, movements of will--desires, hopes, fears and ambitions, no matter to what directed: they are always satisfied at the cost of pain, and in the case of ambition, generally with more or less of illusion. With intellectual pleasure, on the other hand, truth becomes clearer and clearer. In the realm of intelligence pain has no power. Knowledge is all in all.
Further, intellectual pleasures are accessible entirely and only through the medium of the intelligence, and are limited by its capacity. For all the wit there is in the world is useless to him who has none. Still this advantage is accompanied by a substantial disadvantage; for the whole of Nature shows that with the growth of intelligence comes increased capacity for pain, and it is only with the highest degree of intelligence that suffering reaches its supreme point.] The normal, ordinary...

Intellect's Superfluity

Directly extends Schopenhauer's thesis by specifying that happiness comes from a superfluity of intellect enabling a painless intellectual life, reinforcing the superiority of intellectual pleasures.

...work of art, will acquire a consistency, a permanent intensity, a unity which becomes ever more and more complete; compared with which, a life devoted to the attainment of personal comfort, a life that may broaden indeed, but can never be deepened, makes but a poor show: and yet, as I have said, people make this baser sort of existence an end in itself. The ordinary life of every day, so far as it is not moved by passion, is tedious and insipid; and if it is so moved, it soon becomes painful.
Those alone are happy whom nature has favored with some superfluity of intellect, something beyond what is just necessary to carry out the behests of their will; for it enables them to lead an intellectual life as well, a life unattended by pain and full of vivid interests. Mere leisure, that is to say, intellect unoccupied in the service of the will, is not of itself sufficient: there must be a real superfluity of power, set free from the service of the will and devoted to that of the intellect;
for, as Seneca says, otium sine litteris mors est et vivi hominis sepultura--illiterate leisure is a form of death, a living tomb. Varying with the amount of the superfluity, there will be countless developments in this second life, the life of the mind; it may be the mere collection and labelling of insects, birds, minerals, coins, or the highest achievements of poetry and philosophy. The life of the mind is not only a protection against boredom; it also wards off the pernicious effects of b...

Nicomachean Ethics

Pleasure's Accidental Harm

Counters the parent's claim that intellectual activity is free from pain by noting that intense intellectual exercise can harm physical health, introducing a caveat to the painlessness of the intellect.

...stinct from the process: it is true only in the case of such processes as conduce to the perfecting of the natural state. For which reason it is wrong to say that Pleasure is “a sensible process of production.” For “process etc.” should be substituted “active working of the natural state,” for “sensible” “unimpeded.” The reason of its being thought to be a “process etc.” is that it is good in the highest sense: people confusing “active working” and “process,” whereas they really are distinct.
Next, as to the argument that there are bad Pleasures because some things which are pleasant are also hurtful to health, it is the same as saying that some healthful things are bad for “business.” In this sense, of course, both may be said to be bad, but then this does not make them out to be bad simpliciter: the exercise of the pure Intellect sometimes hurts a man’s health: but what hinders Practical Wisdom or any state whatever is, not the Pleasure peculiar to, but some Pleasure foreign to it: the Pleasures arising from the exercise of the pure Intellect or from learning only promote each.
Next. “No Pleasure is the work of any Art.” What else would you expect? No active working is the work of any Art, only the faculty of so working. Still the perfumer’s Art or the cook’s are thought to belong to Pleasure. Next. “The man of Perfected Self-Mastery avoids Pleasures.” “The man of Practical Wisdom aims at escaping Pain rather than at attaining Pleasure.” “Children and brutes pursue Pleasures.” One answer will do for all. We have already said in what sense all Pleasures are good _...

Confessions

Pain Before Pleasure

Explains the parent's observation that non-intellectual pleasures involve pain by asserting a universal pattern: greater joys are preceded by greater pains, illustrating why will-based pursuits are costly.

...eril there was in the battle, so much the more joy is there in the triumph. The storm tosses the sailors, threatens shipwreck; all wax pale at approaching death; sky and sea are calmed, and they are exceeding joyed, as having been exceeding afraid. A friend is sick, and his pulse threatens danger; all who long for his recovery are sick in mind with him. He is restored, though as yet he walks not with his former strength; yet there is such joy, as was not, when before he walked sound and strong.
Yea, the very pleasures of human life men acquire by difficulties, not those only which fall upon us unlooked for, and against our wills, but even by self-chosen, and pleasure-seeking trouble. Eating and drinking have no pleasure, unless there precede the pinching of hunger and thirst. Men, given to drink, eat certain salt meats, to procure a troublesome heat, which the drink allaying, causes pleasure. It is also ordered that the affianced bride should not at once be given, lest as a husband he should hold cheap whom, as betrothed, he sighed not after. This law holds in foul and accursed joy;...
What means this, O Lord my God, whereas Thou art everlastingly joy to Thyself, and some things around Thee evermore rejoice in Thee? What means this, that this portion of things thus ebbs and flows alternately displeased and reconciled? Is this their allotted measure? Is this all Thou hast assigned to them, whereas from the highest heavens to the lowest earth, from the beginning of the world to the end of ages, from the angel to the worm, from the first motion to the last, Thou settest each in...

Nicomachean Ethics

Pleasure's Insufficient Measure

Shifts the focus from pleasure as the criterion to the intrinsic value of intellectual activities and excellences, arguing that we would choose them even if they brought no pleasure.

...ce 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 the...
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 sa...

The Experienced Judge

Questions the possibility of objective measurement of pleasures, implying that judgments about pleasure quality and quantity rely on subjective consensus, thus problematizing the parent's confidence in ranking pleasures.

...or opportunity for indulging them; and they addict themselves to inferior pleasures, not because they deliberately prefer them, but because they are either the only ones to which they have access, or the only ones which they are any longer capable of enjoying. It may be questioned whether any one who has remained equally susceptible to both classes of pleasures, ever knowingly and calmly preferred the lower; though many, in all ages, have broken down in an ineffectual attempt to combine both.
From this verdict of the only competent judges, I apprehend there can be no appeal. On a question which is the best worth having of two pleasures, or which of two modes of existence is the most grateful to the feelings, apart from its moral attributes and from its consequences, the judgment of those who are qualified by knowledge of both, or, if they differ, that of the majority among them, must be admitted as final. And there needs be the less hesitation to accept this judgment respecting the quality of pleasures, since there is no other tribunal to be referred to even on the question of quan...
Neither pains nor pleasures are homogeneous, and pain is always heterogeneous with pleasure. What is there to decide whether a particular pleasure is worth purchasing at the cost of a particular pain, except the feelings and judgment of the experienced? When, therefore, those feelings and judgment declare the pleasures derived from the higher faculties to be preferable in kind, apart from the question of intensity, to those of which the animal nature, disjoined from the higher faculties, is s...

Mind's Inviolable Space

Offers practical guidance: when experiencing pain or pleasure, attribute them to the senses, and recognize that the mind remains inviolable, aligning with the parent's elevation of the intellect over sensory disturbances.

...XXXIX. That which is a hindrance of the senses, is an evil to the sensitive nature. That which is a hindrance of the appetitive and prosecutive faculty, is an evil to the sensitive nature. As of the sensitive, so of the vegetative constitution, whatsoever is a hindrance unto it, is also in that respect an evil unto the same. And so likewise, whatsoever is a hindrance unto the mind and understanding, must needs be the proper evil of the reasonable nature. Now apply all those things unto thyself.
Do either pain or pleasure seize on thee? Let the senses look to that. Hast thou met with Some obstacle or other in thy purpose and intention? If thou didst propose without due reservation and exception now hath thy reasonable part received a blow indeed But if in general thou didst propose unto thyself what soever might be, thou art not thereby either hurt, nor properly hindered. For in those things that properly belong unto the mind, she cannot be hindered by any man. It is not fire, nor iron; nor the power of a tyrant nor the power of a slandering tongue; nor anything else that can penetrat...
XL. If once round and solid, there is no fear that ever it will change. XLI. Why should I grieve myself; who never did willingly grieve any other! One thing rejoices one and another thing another. As for me, this is my joy, if my understanding be right and sound, as neither averse from any man, nor refusing any of those things which as a man I am subject unto; if I can look upon all things in the world meekly and kindly; accept all things and carry myself towards everything according to to tr...
