Narrator: What if the very quality we strive to avoid—foolishness—is the secret ingredient to a happy life? Imagine a world where seriousness, deep thought, and sober wisdom are not virtues but obstacles, preventing us from experiencing joy, forming bonds, and even achieving greatness. This is the provocative and unsettling world presented in Desiderius Erasmus’s masterpiece, In Praise of Folly. Written in 1509, this satirical essay turns our most cherished values on their head, arguing through the voice of a goddess named Folly that it is she, not wisdom, who truly governs the universe and bestows upon humanity its greatest gifts. It is a work that uses humor not just for entertainment, but as a sharp tool to dissect the absurdities of society, the church, and human nature itself.

Narrator: The creation of In Praise of Folly was as spontaneous as the subject it celebrates. Desiderius Erasmus, a towering figure of Renaissance humanism, conceived of the work while traveling from Italy to England in 1509. To pass the time and divert his mind from the tediousness of the journey, he decided to compose a witty panegyric, or formal speech of praise, for the concept of Folly. The work was dedicated to his close friend, the English statesman and fellow humanist Sir Thomas More. The dedication itself is a clever pun, as More’s surname in Greek, Moria, translates directly to "folly."

Erasmus was fully aware that his choice of subject would be controversial. He anticipated that critics would dismiss the work as too frivolous for a respected theologian or too biting for a devout Christian. In his introductory epistle to More, he preemptively defends his methods. He argues that there is a long and distinguished classical tradition of esteemed authors writing on seemingly trivial subjects. He points to Homer, who wrote about a war between frogs and mice, and Virgil, who composed a poem about a gnat. By placing his work in this lineage, Erasmus asserts that lighthearted or absurd topics can serve as vehicles for profound social commentary. He further clarifies that his satire is not aimed at specific individuals but at the universal vices and foolish behaviors of mankind. His goal, he insists, is to instruct and reform through humor, not to maliciously attack.

Narrator: The central conceit of the book is that Folly herself, personified as a goddess, delivers an oration in her own praise. From the outset, she makes a bold and sweeping claim: she is the ultimate source of all joy, pleasure, and vitality in the universe. She argues that the most fundamental aspects of human existence are driven not by cold, calculating wisdom, but by her own impulsive and delightful influence.

Folly begins her argument by claiming responsibility for life itself. She asks what man would be willing to enter the bonds of marriage, with all its troubles, if not for the foolish blindness of love? And what woman would endure the pains of childbirth without the promise of pleasure, which Folly claims as her domain? She contends that procreation stems from a "sportive and tickling recreation," a far cry from the solemn deliberations of a philosopher.

This influence extends throughout the human lifespan. Folly argues that infancy and childhood are the happiest times of life precisely because they are lived in a state of blissful ignorance and foolishness. Old age, too, is made bearable only when the elderly return to a state of second childhood, shedding the anxieties of wisdom. Folly asserts that friendship and marriage, the cornerstones of social life, would be impossible without her. A wise man, she explains, would see every flaw in his friends and spouse, leading to constant conflict. It is only through the foolishness of flattery, self-deception, and overlooking faults that social harmony can be maintained.

Narrator: Folly's argument goes beyond personal happiness and social harmony; she contends that foolishness is superior to wisdom in the practical affairs of the world. She portrays the wise man, the Stoic philosopher, as a passionless and ineffective statue, paralyzed by excessive caution and deliberation. Such a man, she claims, would shrink from any great undertaking for fear of failure. In contrast, the fool, unburdened by foresight and shame, rushes into action and often achieves great things through sheer audacity.

To illustrate this point, Erasmus uses Folly to retell several historical anecdotes. One powerful example is the story of the Roman general Sertorius, who needed to teach his soldiers the value of strategy over brute force. He presented two horses to his army. He commanded a strong, robust soldier to pull the entire tail from one horse at once, an impossible task. He then ordered a weak, feeble soldier to pluck the hairs from the other horse's tail one by one. The weak soldier easily succeeded where the strong one failed. Through this simple, almost foolish demonstration, Sertorius taught a profound lesson that a long, dry philosophical lecture could never have conveyed. Folly argues that such clever tricks and fables are her tools, proving that wit and a touch of foolishness are more effective than solemn wisdom in governing and leading men.

Narrator: A significant portion of Folly's oration is a sweeping critique of the various professions and classes of society, in which she reveals that those who believe themselves to be the wisest are often the most deluded. She spares no one in her satirical assault. Grammarians are portrayed as miserable pedants who torture children over trivial rules. Poets and authors are consumed by a thirst for fame, endlessly flattering one another. Lawyers and logicians bury truth under mountains of convoluted arguments and nonsensical syllogisms.

Folly saves her sharpest barbs for theologians and churchmen. She mocks the scholastic theologians for debating absurdly specific and unknowable questions, such as how many angels can dance on the head of a pin, while ignoring the simple, core teachings of the Gospels. She criticizes monks and friars for their obsession with minute regulations regarding their dress and daily routines, believing these external details will grant them entry into heaven. Popes, cardinals, and bishops are depicted as having abandoned their spiritual duties in favor of wealth, power, and worldly pomp, becoming more like secular princes than shepherds of Christ's flock. By showing that every corner of society is rife with its own particular brand of foolishness, Erasmus makes the case that folly is a universal and inescapable part of the human condition.

Narrator: In her most daring and profound argument, Folly connects foolishness directly to religious faith and the attainment of ultimate happiness. She argues that the Christian religion itself has a "certain kinship with folly." True faith, she contends, requires a belief in mysteries that defy rational explanation. The most devout Christians are those who embrace this "foolishness of God," which St. Paul wrote is "wiser than men." They cast aside worldly wisdom, which is concerned with material things, and embrace a spiritual reality that appears foolish to the unenlightened.

Folly concludes her speech by describing the ultimate happiness promised to the pious as a form of divine madness or ecstasy. This is a state in which the soul is so enraptured by the contemplation of the divine that it is drawn out of the body and loses all sense of the material world. This transcendent state, she argues, is the highest form of pleasure and the ultimate reward for a life of faith. It is a complete departure from reason and a total immersion in a spiritual folly. In this final, brilliant stroke, Erasmus elevates folly from a source of simple pleasure to the very pathway to salvation, completing his radical inversion of conventional wisdom.

Narrator: The single most important takeaway from In Praise of Folly is its radical assertion that folly is not a defect but an essential, life-giving force. Erasmus argues that human happiness, social cohesion, and even spiritual fulfillment are fundamentally dependent on our capacity for foolishness—our ability to love blindly, act boldly without perfect knowledge, tolerate each other's imperfections, and believe in things that transcend reason. The book is a masterful defense of the irrational, emotional, and imperfect aspects of human nature against the tyranny of a cold and sterile wisdom.

More than five centuries after it was written, the work's challenge remains as potent as ever. It forces us to look at our own lives, our institutions, and our most deeply held beliefs and ask a disquieting question: In our relentless pursuit of wisdom, seriousness, and rationality, what essential joys and truths have we dismissed as mere folly?
