The German philosopher Nietzsche called this book the finest thing Europe ever produced. He said it had not created anything else “more complicated in matters of moral subtlety.”
His predecessor Arthur Schopenhauer also thought well of the work, saying that the maxims are “especially fitted to those who wish to prosper in the great world.”
The book in question is his The Art of Worldly Wisdom. Written by Baltasar Gracian, a 17th century Jesuit priest, it contains hundreds of rules for life.
His maxims have much in common with Stoic philosophy. His focus on the virtue of prudence overlaps nicely with Stoicism. If you can embody his philosophy you would go a long way towards capturing essential aspects of classical wisdom.
You may find these particular rules about what not to do useful. I did.
7. Don’t outshine your boss.
Being defeated is hateful, and besting one’s boss is either foolish or fatal. Superiority is always odious, especially to superiors and sovereigns. The common sort of advantages can be cautiously hidden, as beauty is hidden with a touch of artful neglect. Most people do not mind being surpassed in good fortune, character, or temperament, but no one, especially not a sovereign, likes to be surpassed in intelligence. For this is the king of attributes, and any crime against it is lese-majeste. Sovereigns want to be so in what is most important. Princes like to be helped, but not surpassed. When you counsel someone, you should appear to be reminding him of something he had forgotten, not of the light he was unable to see. It is the stars who teach us this subtlety. They are brilliant sons, but they never dare to outshine the sun.
30. Don’t occupy yourself with disreputable things
Even less with chimerical ones that bring more scorn than renown. Caprice has founded many sects, and the sane person should flee from all of them. There are people with extravagant tastes who embrace anything wise people repudiate. They take pleasure in any sort of eccentricity, and although this makes them well known, they are more often laughed at than renowned. Even when pursuing wisdom the prudent ought to shun affectation and public notice, especially in things that can make them look ridiculous. There is no use pointing out these pursuits one by one: common ridicule has already done so.
69. Don’t give into every common impulse
The great do not yield to every sort of passing thought. Part of prudence lies in reflecting about yourself: knowing or foreseeing your disposition, and moving towards the other extreme in order to balance art and nature. Self-correction begins with self-knowledge. There are monsters of impertinence who are always ruled by a certain humor, and their emotions vary accordingly. Tossed about by this vile imbalance, they go about their business in a self-contradictory way. Not only does this excess ruin their will, it also attacks their judgment, trouble their desire and understanding.
71. Don’t be inconsistent
The prudent man is consistent in all things pertaining to perfection, and this speaks well for his intelligence. Only the causes and relative merits of things can change his behavior. When it comes to prudence, variety is ugly. There are some people who are different each day. Their luck changes daily, and so do their will and their powers of understanding. Yesterday they conceded; today they receded. They belie their own reputation, confusing others.
74. Don’t be unfriendly
The wildest animals inhabit cities. Being unapproachable is the vice of those who lack self-knowledge and who change humors with honors. To begin by annoying others is no way to win renown. Imagine one of these surly monsters, always about to turn savage and impertinent. His unlucky servants approach him as though he were a tiger, arming themselves cautiously with a whip. In order to reach their high position they pleased everyone, and now that they are there they want to get even by angering everyone. Because of their position, such people ought to belong to everyone, but their harshness and vanity makes them belong to no one. A courtly punishment for them: avoid them entirely. Bestow your wisdom on others.
79. Don’t always be joking
Prudence is known for its seriousness, which wins more respect than wit. The person who is always joking falls laughably short of perfection. We treat him like a liar, never believing him. From one we fear deceit, from the other jest. One never knows when jokers are exercising their judgment, which is the same as not having any. No humor is worse than continual humor. Some win a reputation for wit, and lose their wits. There are moments for joviality, but the rest of the time belongs to seriousness.
110. Don’t wait to be a setting sun
It is a maxim of prudent people to abandon things before being abandoned by them. You should make even your end into a triumph. At times the sun itself retires behind a cloud so that no one will see it fall, and it leaves us wondering whether it has set or not. Avoid sunsets so as not to burst with misfortune. Don’t wait for people to turn their shoulders on you: they will bury you alive to your regret, dead to renown. The prudent know when to retire a racehorse, and do not wait for him to collapse in the middle of the race, to the laughter of all. Let Beauty shatter the mirror cleverly, at the right time, and not too late when she cannot bear the truth.
The rest of the work contains a wealth of additional maxims. It’s the kind of book suitable for leafing through a few pages and contemplating each one. It is short, but not a short read. If you get the chance to go through it, let us know and share the maxims you found most useful.
