The Inner Self
Arthur Schopenhauer
The Wisdom of Life

The author contends that internal intellectual resources are more essential than external possessions, as a thinker finds entertainment in solitude while a dullard suffers even amidst amusements.

...d Youth and Age cannot live together, up to the life of the Genius and the Saint. Health outweighs all other blessings so much that one may really say that a healthy beggar is happier than an ailing king. A quiet and cheerful temperament, happy in the enjoyment of a perfectly sound physique, an intellect clear, lively, penetrating and seeing things as they are, a moderate and gentle will, and therefore a good conscience--these are privileges which no rank or wealth can make up for or replace.
For what a man is in himself, what accompanies him when he is alone, what no one can give or take away, is obviously more essential to him than everything he has in the way of possessions, or even what he may be in the eyes of the world. An intellectual man in complete solitude has excellent entertainment in his own thoughts and fancies, while no amount of diversity or social pleasure, theatres, excursions and amusements, can ward off boredom from a dullard.
A good, temperate, gentle character can be happy in needy circumstances, whilst a covetous, envious and malicious man, even if he be the richest in the world, goes miserable. Nay more; to one who has the constant delight of a special individuality, with a high degree of intellect, most of the pleasures which are run after by mankind are simply superfluous; they are even a trouble and a burden. And so Horace says of himself, that, however many are deprived of the fancy-goods of life, there is on...

Solitude's Revelation

This excerpt directly echoes the parent's claim by illustrating how solitude reveals a person's inner resources: the fool suffers under his own personality while the talented person enriches solitude with thought, reinforcing the contrast between the intellectual and the dullard.

...why a high degree of intellect tends to make a man unsocial. True, if quality of intellect could be made up for by quantity, it might be worth while to live even in the great world; but unfortunately, a hundred fools together will not make one wise man. But the individual who stands at the other end of the scale is no sooner free from the pangs of need than he endeavors to get pastime and society at any cost, taking up with the first person he meets, and avoiding nothing so much as himself.
For in solitude, where every one is thrown upon his own resources, what a man has in himself comes to light; the fool in fine raiment groans under the burden of his miserable personality, a burden which he can never throw off, whilst the man of talent peoples the waste places with his animating thoughts.
Seneca declares that folly is its own burden,--omnis stultitia laborat fastidio sui,--a very true saying, with which may be compared the words of Jesus, the son of Sirach, The life of a fool is worse than death[1]. And, as a rule, it will be found that a man is sociable just in the degree in which he is intellectually poor and generally vulgar. For one's choice in this world does not go much beyond solitude on one side and vulgarity on the other. It is said that the most sociable of all peo...

Pensees

Rest's Unbearable Void

Pascal challenges the parent's assertion that an intellectual person finds ample entertainment in solitude by arguing that complete rest without passions or diversion leads humans to feel their emptiness and despair, implying solitude is inherently insufferable.

...weariness which is felt by us in leaving pursuits to which we are attached. A man dwells at home with pleasure; but if he sees a woman who charms him, or if he enjoys himself in play for five or six days, he is miserable if he returns to his former way of living. Nothing is more common than that. 129 Our nature consists in motion; complete rest is death.[65] 130 Restlessness.--If a soldier, or labourer, complain of the hardship of his lot, set him to do nothing. 131 Weariness.[66]--
Nothing is so insufferable to man as to be completely at rest, without passions, without business, without diversion, without study. He then feels his nothingness, his forlornness, his insufficiency, his dependence, his weakness, his emptiness. There will immediately arise from the depth of his heart weariness, gloom, sadness, fretfulness, vexation, despair.
132 Methinks Cæsar was too old to set about amusing himself with conquering the world.[67] Such sport was good for Augustus or Alexander. They were still young men, and thus difficult to restrain. But Cæsar should have been more mature. 133 Two faces which resemble each other, make us laugh, when together, by their resemblance, though neither of them by itself makes us laugh. 134 How useless is painting, which attracts admiration by the resemblance of things, the originals of which we...

Inward Wealth's Protection

This excerpt explains the psychological mechanism behind the parent's claim: inward wealth of the mind leaves no room for boredom because thought is an inexhaustible activity that constantly engages itself with new material.

...and spirits something to occupy them. The kind of things people choose for this purpose shows that they are not very particular, as witness the miserable pastimes they have recourse to, and their ideas of social pleasure and conversation: or again, the number of people who gossip on the doorstep or gape out of the window. It is mainly because of this inner vacuity of soul that people go in quest of society, diversion, amusement, luxury of every sort, which lead many to extravagance and misery.
Nothing is so good a protection against such misery as inward wealth, the wealth of the mind, because the greater it grows, the less room it leaves for boredom. The inexhaustible activity of thought! Finding ever new material to work upon in the multifarious phenomena of self and nature, and able and ready to form new combinations of them,--there you have something that invigorates the mind, and apart from moments of relaxation, sets it far above the reach of boredom.
[Footnote 1: And the extremes meet; for the lowest state of civilization, a nomad or wandering life, finds its counterpart in the highest, where everyone is at times a tourist. The earlier stage was a case of necessity; the latter is a remedy for boredom.] But, on the other hand, this high degree of intelligence is rooted in a high degree of susceptibility, greater strength of will, greater passionateness; and from the union of these qualities comes an increased capacity for emotion, an enhan...

The Exception's Burden

Nietzsche reframes the issue from one of inner happiness versus boredom to the dynamic between the exceptional individual and the common rule, suggesting the real tension is whether the exception remains isolated or engages with the majority.

...with artistic curiosity, with regard to many a philosopher it is easy to understand the dangerous desire to see him also in his deterioration (deteriorated into a "martyr," into a stage-and-tribune-bawler). Only, that it is necessary with such a desire to be clear WHAT spectacle one will see in any case--merely a satyric play, merely an epilogue farce, merely the continued proof that the long, real tragedy IS AT AN END, supposing that every philosophy has been a long tragedy in its origin. 26.
Every select man strives instinctively for a citadel and a privacy, where he is FREE from the crowd, the many, the majority--where he may forget "men who are the rule," as their exception;--exclusive only of the case in which he is pushed straight to such men by a still stronger instinct, as a discerner in the great and exceptional sense. Whoever, in intercourse with men, does not occasionally glisten in all the green and grey colours of distress, owing to disgust, satiety, sympathy, gloominess, and solitariness, is assuredly not a man of elevated tastes; supposing, however, that he does not v...
The long and serious study of the AVERAGE man--and consequently much disguise, self-overcoming, familiarity, and bad intercourse (all intercourse is bad intercourse except with one's equals):--that constitutes a necessary part of the life-history of every philosopher; perhaps the most disagreeable, odious, and disappointing part. If he is fortunate, however, as a favourite child of knowledge should be, he will meet with suitable auxiliaries who will shorten and lighten his task; I mean so-calle...

Master of Emotions

Nietzsche offers practical guidance on living as a select individual: cultivate tranquility, control one's emotions and appearances, employ politeness, and master virtues including solitude to maintain purity amid impure society.

...tunity and provocation to constant MISUNDERSTANDING. To be able to allow oneself this veritable luxury of taste and morality, one must not live among intellectual imbeciles, but rather among men whose misunderstandings and mistakes amuse by their refinement--or one will have to pay dearly for it!--"He praises me, THEREFORE he acknowledges me to be right"--this asinine method of inference spoils half of the life of us recluses, for it brings the asses into our neighbourhood and friendship. 284.
To live in a vast and proud tranquility; always beyond... To have, or not to have, one's emotions, one's For and Against, according to choice; to lower oneself to them for hours; to SEAT oneself on them as upon horses, and often as upon asses:--for one must know how to make use of their stupidity as well as of their fire. To conserve one's three hundred foregrounds; also one's black spectacles: for there are circumstances when nobody must look into our eyes, still less into our "motives." And to choose for company that roguish and cheerful vice, politeness. And to remain master of one's four v...
285. The greatest events and thoughts--the greatest thoughts, however, are the greatest events--are longest in being comprehended: the generations which are contemporary with them do not EXPERIENCE such events--they live past them. Something happens there as in the realm of stars. The light of the furthest stars is longest in reaching man; and before it has arrived man DENIES--that there are stars there. "How many centuries does a mind require to be understood?"--that is also a standard, one a...
