What I've learned from "The Art of Worldly Wisdom" by Baltasar Gracian

This is a great book of wisdom written by a Spanish Jesuit and baroque prose writer and philosopher. Baltasar Gracián. Gracian was one of the wisest men who lived, and this is the inspiration from his wisdom. For example, 1) When dependence disappears, good behaviour goes with it as well as respect. 2) The best remedy for disturbances is to let them run their course, for so they quiet down. 3) Do not Believe, or Like, lightly. Maturity of mind is best shown in slow belief. 4) Excellence resides in quality not in quantity. The best is always few and rare: much lowers value. 5) To be occupied in what does not concern you is worse than doing nothing.

This is my book summary of The Art of Worldly Wisdom by Baltasar Gracian. My notes are informal. This summary is my favourite passages from the book.

• “The sole advantage of power is that you can do more good”
  is the only rational defence of ambition, and Gracian employs it
• Knowledge and Courage are the elements of Greatness. They give immortality, because they are immortal. Each is as much as he knows, and the wise can do anything. A man without knowledge, a world without light. Wisdom and strength, eyes and hands. Knowledge without courage is sterile.
• The wise man would rather see men needing him than thanking him. To keep them on the threshold of hope is diplomatic, to trust to their gratitude boorish; hope has a good memory, gratitude a bad one. More is to be got from dependence than from courtesy.
• When dependence disappears, good behaviour goes with it as well as respect.
• A bad manner spoils everything, even reason and justice; a good one supplies everything, gilds a No, sweetens truth, and adds a touch of beauty to old age itself. The how plays a large part in affairs, a good manner steals into the affections. Fine behaviour is a joy in life, and a pleasant expression helps out of a difficulty in a remarkable way.
• ’Tis a great thing to know, little to live: no real life without knowledge. There is remarkable cleverness in studying without study, in getting much by means of many, and through them all to become wise.
• Mediocrity obtains more with application than superiority without it. Work is the price which is paid for reputation. What costs little is little worth.
• The rarest individuals depend on their age. It is not every one that finds the age he deserves, and even when he finds it he does not always know how to utilise it. Some men have been worthy of a better century, for every species of good does not always triumph. Things have their period; even excellences are subject to fashion.
• There are rules of luck: it is not all chance with the wise: it can be assisted by care. Some content themselves with placing them-selves confidently at the gate of Fortune, waiting till she opens it. Others do better, and press forward and profit by their clever boldness, reaching the goddess and winning her favour on the wings of their virtue and valour. But on a true philosophy there is no other umpire than virtue and insight; for there is no luck or ill-luck except wisdom and the reverse.
• Excellence resides in quality not in quantity. The best is always few and rare: much lowers value.
• When in doubt, follow the suit of the wise and prudent; sooner or later they will win the odd trick.
• That is the great advantage of a commanding position—to be able to do more good than others. Those make friends who do friendly acts.
• To be occupied in what does not concern you is worse than doing nothing.
• It is a great piece of skill to know how to guide your luck even while waiting for it. For something is to be done with it by waiting so as to use it at the proper moment, since it has periods and offers opportunities, though one cannot calculate its path, its steps are so irregular. When you find Fortune favourable, stride boldly forward, for she favours the bold and, being a woman, the young.
• The wise man therefore retires into silence, and if he allows himself to come out of it, he does so in the shade and before few and fit persons.
• Good sense masters this feeling, for there is nothing more discreditable than to dislike those better than ourselves. As sympathy with great men en-nobles us, so dislike to them degrades us.
• Never lose Self-respect, or be too familiar with oneself. Let your own right feeling be the true standard of your rectitude, and owe more to the strictness of your own self-judgment than to all external sanctions. Leave off anything unseemly more from regard for your own self-respect than from fear of external authority.
• Diligence promptly executes what intelligence slowly excogitates. Hurry is the failing of fools; they know not the crucial point and set to work without preparation. On the other hand, the wise more often fail from procrastination; foresight begets deliberation, and remiss action often nullifies prompt judgment. Celerity is the mother of good fortune.
• It’s a sign of a noble heart dowered with patience, never to be in a hurry, never to be in a passion. First be master over yourself if you would be master over others. You must pass through the circumference of time before arriving at the centre of opportunity
• Early enough if well. Quickly done can be quickly undone. To last an eternity requires an eternity of preparation. Only excellence counts; only achievement endures. Profound intelligence is the only foundation for immortality. Worth much costs much. The precious metals are the heaviest.
• There is no need to show your ability before every one. Employ no more force than is necessary. Let there be no unnecessary expenditure either of knowledge or of power.
• If there is too much display to-day there will be nothing to show to-morrow. Always have some novelty wherewith to dazzle. To show something fresh each day keeps expectation alive and conceals the limits of capacity.
  Fortune rarely accompanies any one to the door: warmly as she may welcome the coming, she speeds but coldly the parting guest.
• Avoid Worry. Such prudence brings its own reward. It escapes much, and is thus the midwife of comfort and so of happiness. Neither give nor take bad news unless it can help.
• He is a great man who never allows himself to be influenced by the impressions of others. Self-reflection is the school of wisdom.
• Self-knowledge is the beginning of self-improvement. There be some whose humours are so monstrous that they are always under the influence of one or other of them, and put them in place of their real inclinations.
• Your refusal need not be point-blank: let the disappointment come by degrees. Nor let the refusal be final; that would be to destroy dependence; let some spice of hope remain to soften the rejection. Let politeness compensate and fine words supply the place of deeds. Yes and No are soon said, but give much to think over.
• There are some who are different every day; their intelligence varies, still more their will, and with this their fortune. * * * Yesterday’s white is to-day’s black: to-day’s No was yesterday’s Yes. They always give the lie to their own credit and destroy their credit with others.
• Utilise Slips. That is how smart people get out of difficulties. They extricate themselves from the most intricate labyrinth by some witty application of a bright remark. They get out of a serious contention by an airy nothing or by raising a smile. Most of the great leaders are well grounded in this art. When you have to refuse, it is often the polite way to talk of something else. Sometimes it proves the highest understanding not to understand.
• Do not be Unsociable. The truest wild beasts live in the most populous places. To be inaccessible is the fault of those who distrust themselves, whose honours change their manners. It is no way of earning people’s goodwill by being ill-tempered with them.
• The truest wild beasts live in the most populous places. To be inaccessible is the fault of those who distrust themselves, whose honours change their manners. It is no way of earning people’s goodwill by being ill-tempered with them.
• Choose an Heroic Ideal; but rather to emulate than to imitate. There are exemplars of greatness, living texts of honour. * Let every one have before his mind the chief of his calling not so much to follow him as to spur himself on.
• Do not always be Jesting. Wisdom is shown in serious matters, and is more appreciated than mere wit. He that is always ready for jests is never ready for serious things. They resemble liars in that men never believe either, always expecting a lie in one, a joke in the other. One never knows when you speak with judgment, which is the same as if you had none. A continual jest soon loses all zest. Many get the repute of being witty, but thereby lose the credit of being sensible. Jest has its little hour, seriousness should have all the rest.
• Every rush forward is freed from danger by caution, while fortune some-times helps in such cases. Step cautiously where you suspect depth. Sagacity goes cautiously forward while precaution covers the ground.
• For there are things you must take in fun, though others perhaps mean them in earnest. You show a sense of placability, which acts as a magnet on all hearts.
• Try therefore to be born again in valour, in genius, in fortune, in all. Display startling novelties, rise afresh like the sun every day. Change too the scene on which you shine, so that your loss may be felt in the old scenes of your triumph, while the novelty of your powers wins you applause in the new.
• Even in enjoyment never go to extremes. Thought too subtle is dull. If you milk a cow too much you draw blood, not milk.
• You should learn to seize things not by the blade, which cuts, but by the handle, which saves you from harm: especially is this the rule with the doings of your enemies. A wise man gets more use from his enemies than a fool from his friends.
• Many have had their greatness made for them by their enemies. Flattery is more dangerous than hatred, because it covers the stains which the other causes to be wiped out. The wise will turn ill-will into a mirror more faithful than that of kindness. and remove or improve the faults referred to.
• Be extraordinary in your excellence, if you like, but be ordinary in your display of it. The more light a torch gives, the more it burns away and the nearer ’tis to going out. Show yourself less and you will be rewarded by being esteemed more.
• It is easy to get into bad repute, because it is easy to believe evil of any one: it is not easy to clear yourself. The wise accordingly avoid these mischances, guarding against vulgar scandal with sedulous vigilance. It is far easier to prevent than to rectify.
• Let your Behaviour be Fine and Noble. A great man ought not to be little in his behaviour. He ought never to pry too minutely into things, least of all in unpleasant matters. For though it is important to know all, it is not necessary to know all about all.
• Generally speaking, every man behaves according to his heart and his understanding.
• Know Yourself —in talents and capacity, in judgment and inclination. You cannot master yourself unless you know yourself. There are mirrors for the face but none for the mind. Let careful thought about yourself serve as a substitute. * * When the outer image is forgotten, keep the inner one to improve and perfect. Learn the force of your intellect and capacity for affairs, test the force of your courage in order to apply it, and keep your foundations secure and your head clear for everything.
• Lead a good life. Two things bring life speedily to an end: folly and immorality. Some lose their life because they have not the intelligence to keep it, others because they have not the will.
• A virtuous life never dies. The firmness of the soul is communicated to the body, and a good life is long not only in intention but also in extension.
• Action is dangerous where prudence is in doubt: better leave such things alone. Wisdom does not trust to probabilities; it always marches in the mid-day light of reason.
• Keep the extent of your Abilities unknown. The wise man does not allow his knowledge and abilities to be sounded to the bottom, if he desires to be honoured by all. He allows you to know them but not to comprehend them. No one must know the extent of his abilities, lest he be disappointed. No one ever has an opportunity of fathoming him entirely. For guesses and doubts about the extent of his talents arouse more veneration than accurate knowledge of them, be they ever so great.
• Keep Expectation alive. Keep stirring it up. Let much promise more, and great deeds herald greater.
• Reality and Appearance. Things pass for what they seem, not for what they are. Few see inside; many take to the outside. It is not enough to be right, if right seem false and ill.
• A man of talent therefore should show that he has more room for even greater enterprises, and above all avoid showing signs of a little heart.
• If you wish to be valued, be valued for your talents, not for anything adventitious. Even kings prefer to be honoured for their personal qualifications rather than for their station.
• A noble nature, on the contrary, always knows how to find an excuse for failings, if not in the intention, at least from oversight.
• Do not wait till you are a Sinking Sun. ’Tis a maxim of the wise to leave things before things leave them. One should be able to snatch a triumph at the end, just as the sun even at its brightest often retires behind a cloud so as not to be seen sinking, and to leave in doubt whether he has sunk or no.
• The most and best of us depend on others; we have to live either among friends or among enemies. Seek some one every day to be a well-wisher if not a friend; by and by after trial some of these will become intimate.
  In Prosperity prepare for Adversity. It is both wiser and easier to collect winter stores in summer. In prosperity favours are cheap and friends are many. ’Tis well therefore to keep them for more unlucky days, for adversity costs dear and has no helpers. Retain a store of friendly and obliged persons; the day may come when their price will go up. Low minds never have friends; in luck they will not recognise them: in misfortune they will not be recognised by them.
• Many have lived in good repute while they had no rivals. The heat of conflict gives life, or even new life, to dead scandals, and digs up long-buried skeletons.
• Men of good-will are always at peace; men of good repute and dignity are men of good-will.
• Get used to the Failings of your Familiars, as you do to ugly faces. It is indispensable if they depend on us, or we on them. There are wretched characters with whom one cannot live, nor yet without them. Therefore clever folk get used to them, as to ugly faces, so that they are not obliged to do so suddenly under the pressure of necessity.
• Only act with Honourable Men. You can trust them and they you. Their honour is the best surety of their behaviour even in misunderstandings, for they always act having regard to what they are.
• Never talk of Yourself. You must either praise yourself, which is vain, or blame yourself, which is little-minded: it ill beseems him that speaks, and ill pleases him that hears. And if you should avoid this in ordinary conversation, how much more in official matters, and above all, in public speaking, where every appearance of unwisdom really is unwise. * The same want of tact lies in speaking of a man in his presence, owing to the danger of going to one of two extremes: flattery or censure.
• Avoid becoming Disliked. There is no occasion to seek dislike: it comes without seeking quickly enough.
  In the adornment of the body as of the mind adapt yourself to the present, even though the past appear better. But this rule does not apply to kindness, for goodness is for all time. It is neglected nowadays and seems out of date. Truth-speaking, keeping your word, and so too good people, seem to come from the good old times: yet they are liked for all that, but in such a way that even when they all exist they are not in the fashion and are not imitated. What
  If you are wise, live as you can, if you cannot live as you would. Think more highly of what fate has given you than of what it has denied.
• Do not make a Business of what is no Business. As some make gossip out of everything, so others business. They always talk big, take everything in earnest, and turn it into a dispute or a secret. Troublesome things must not be taken too seriously if they can be avoided. It is preposterous to take to heart that which you should throw over your shoulders.
• Distinction in Speech and Action. By this you gain a position in many places and carry esteem beforehand. It shows itself in everything, in talk, in look, even in gait. It is a great victory to conquer men’s hearts: it does not arise from any foolish presumption or pompous talk, but in a becoming tone of authority born of superior talent combined with true merit.
• You should keep your desires sealed up, still more your defects. All go wrong sometimes, but the wise try to hide the errors, but fools boast of them. Reputation depends more on what is hidden than on what is done; if a man does not live chastely, he must live cautiously.
• But here one can help with that other great rule of life: learn to forget.
• Never complain. To complain always brings discredit. Better be a model of self-reliance opposed to the passion of others than an object of their compassion. For
• Do and be seen Doing. Things do not pass for what they are but for what they seem. To be of use and to know how to show yourself of use, is to be twice as useful.
• The greatest wisdom often consists in ignorance, or the pretence of it. One has to live with others, and others are mostly ignorant. “To live entirely alone one must be very like a god or quite like a wild beast,” but I would turn the aphorism by saying: Better be wise with the many than a fool all alone. There be some too who seek to be original by seeking chimeras.
• The best remedy for disturbances is to let them run their course, for so they quiet down.
• Recognise unlucky Days. They exist: nothing goes well on them; even though the game may be changed the ill-luck remains. Two tries should be enough to tell if one is in luck to-day or not.
• To speak and at the same time listen to yourself cannot turn out well. If to talk to oneself when alone is folly, it must be doubly unwise to listen to oneself in the presence of others.
• Those who cannot or dare not reach great deeds on the direct road of excellence go round by way of Paradox, admired by fools but making wise men true prophets. It argues an unbalanced judgment, and if it is not altogether based on the false, it is certainly founded on the uncertain, and risks the weightier matters of life.
• Do not be Inaccessible. None is so perfect that he does not need at times the advice of others.
• The highest should have the door open for friendship; it may prove the gate of help. A friend must be free to advise, and even to upbraid, without feeling embarrassed. Our satisfaction in him and our trust in his steadfast faith give him that power. One need not pay respect or give credit to every one, but in the innermost of his precaution man has a true mirror of a confidant to whom he owes the correction of his errors, and has to thank for it.
• Never call things easy or common: that makes them depreciated rather than made accessible. All rush after the unusual, which is more appetising both for the taste and for the intelligence.
• Never have a Companion who casts you in the Shade. The more he does so, the less desirable a companion he is. The more he excels in quality the more in repute: he will always play first fiddle and you second. If you get any consideration, it is only his leavings. The moon shines bright alone among the stars: when the sun rises she becomes either invisible or imperceptible. Never join one that eclipses you, but rather one who sets you in a brighter light.
• Do not Believe, or Like, lightly. Maturity of mind is best shown in slow belief.
• The insight of a true friend is more useful than the goodwill of others: therefore gain them by choice, not by chance. A wise friend wards off worries, a foolish one brings them about. But do not wish them too much luck, or you may lose them.
• Do not make Mistakes about Character. That is the worst and yet easiest error. Better be cheated in the price than in the quality of goods. In dealing with men, more than with other things, it is necessary to look within. To know men is different from knowing things. It is profound philosophy to sound the depths of feeling and distinguish traits of character. Men must be studied as deeply as books.
• Make use of your Friends. This requires all the art of discretion. Some are good afar off, some when near. Many are no good at conversation but excellent as correspondents, for distance removes some failings which are unbearable in close proximity to them.
• Few are worthy to be good friends, and even these become fewer because men do not know how to pick them out. To keep is more important than to make friends. Select those that will wear well; if they are new at first, it is some consolation they will become old. Absolutely the best are those well salted, though they may require soaking in the testing. There is no desert like living without friends. Friendship multiplies the good of life and divides the evil. ’Tis the sole remedy against misfortune, the very ventilation of the soul.
• Put up with Fools. The wise are always impatient, for he that increases knowledge increase impatience of folly. Much knowledge is difficult to satisfy. The first great rule of life, according to Epictetus, is to put up with things: he makes that the moiety of wisdom. To put up with all the varieties of folly would need much patience.
• Be careful in Speaking. With your rivals from prudence; with others for the sake of appearance. There is always time to add a word, never to withdraw one. Talk as if you were making your will: the fewer words the less litigation. In trivial matters exercise yourself for the more weighty matters of speech. Profound secrecy has some of the lustre of the divine. * He who speaks lightly soon falls or fails.
• He that knows himself knows how to strengthen his weakness, and the wise man conquers everything, even the stars in their courses.
• Nothing is more valuable than a protector, and nothing costs more nowadays than a favour. It can make or unmake a whole world. It can even give sense and take it away. As Nature and Fame are favourable to the wise, so Luck is generally envious of them. It is therefore more important to keep the favour of the mighty than goods and chattels.
• A man of honour and responsibility has a reputation, because he has much to lose. He balances his own and the other’s reputation: he only enters into the contest with the greatest caution, and then goes to work with such circumspection that he gives time to prudence to retire in time and bring his reputation under cover. For even by victory he cannot gain what he has lost by exposing himself to the chances of loss.
• Do not live in a Hurry. To know how to separate things is to know how to enjoy them. Many finish their fortune sooner than their life: they run through pleasures without enjoying them, and would like to go back when they find they have over-leaped the mark.
• We have more days to live through than pleasures. Be slow in enjoyment, quick at work, for men see work ended with pleasure, pleasure ended with regret.
• Many would be wise if they did not think themselves wise. Thus
• Trust your Heart, especially when it has been proved. Never deny it a hearing. It is a kind of house oracle that often foretells the most important. Many have perished because they feared their own heart, but of what use is it to fear it without finding a better remedy? Many are endowed by Nature with a heart so true that it always warns them of misfortune and wards off its effects. It is unwise to seek evils, unless you seek to conquer them.
• What must be done need not be said, and what must be said need not be done.
• Yet not all truths can be spoken: some for our own sake, others for the sake of others.
• Do pleasant Things Yourself, unpleasant Things through Others. By the one course you gain goodwill, by the other you avoid hatred. A great man takes more pleasure in doing a favour than in receiving one: it is the privilege of his generous nature.
• Be the Bearer of Praise. This increases our credit for good taste, since it shows that we have learnt elsewhere to know what is excellent, and hence how to prize it in the present company. It gives material for conversation and for imitation, and encourages praiseworthy exertions.
• Peaceful Life, a long Life. To live, let live. Peacemakers not only live: they rule life. Hear, see, and be silent. A day without dispute brings sleep without dreams. Long life and a pleasant one is life enough for two: that is the fruit of peace. He has all that makes nothing of what is nothing to him. There is no greater perversity than to take everything to heart. There is equal folly in troubling our heart about what does not concern us and in not taking to heart what does.
• The wise man anticipates such errors: he may always hope for the best. but he always expects the worst, so as to receive what comes with equanimity. True, It is wise to aim high so as to hit your mark, but not so high that you miss your mission at the very beginning of life. This correction of the ideas is necessary, because before experience comes expectation is sure to soar too high. The best panacea against folly is prudence. If a man knows the true sphere of his activity and position, the can reconcile his ideals with reality.
• To know how to make use of every one is useful knowledge. Wise men appreciate all men, for they see the good in each and know how hard it is to make anything good. Fools depreciate all men, not recognising the good and selecting the bad.
• Do not carry Fools on your Back. He that does not know a fool when he sees him is one himself: still more he that knows him but will not keep clear of him. They are dangerous company and ruinous confidants.
