The March of Folly: From Troy to Vietnam: Summary & Key Insights

Let us begin with myth, where folly takes its purest symbolic form. The Trojan horse is not simply a tale of trickery; it is a parable of human blindness to reason. The Trojans had endured ten years of war and were desperate for respite. When they beheld the Greeks apparently sailing away, leaving behind a magnificent wooden horse, caution was overcome by hope. Prophets and citizens alike warned against bringing it into the city—Laocoön and Cassandra most famously—but their voices were mocked, ignored, and even punished. The horse was hauled inside as a trophy, an offering to Athena, and with that decision, Troy sealed its fate.

In examining this legend, I am less concerned with its historicity than with what it reveals about the anatomy of political folly. Every element is present: the rejection of wise counsel, the preference for comforting illusion over painful reality, and the collective rationalization that transforms doubt into betrayal. The Trojans wanted the war to be over; they wanted the symbol of their suffering transfigured into triumph. And so they contrived to see in the horse what they wished it to be. The mechanism of self-deception was complete.

Throughout history, governments have reenacted Trojan folly by substituting wishful belief for rational calculation. Once a policy becomes entwined with pride or ideology, evidence loses its force. Those who question it become inconvenient, even enemies within. Cassandra’s fate—foreknowledge without power to persuade—has echoed in the voices of countless diplomats, advisers, and strategists across the centuries.

No era better demonstrates institutional blindness than the Renaissance papacy. The popes of the 15th and early 16th centuries—Sixtus IV, Alexander VI, Julius II, Leo X—embodied the paradox of supreme spiritual authority corrupted by temporal indulgence. They poured the Church’s wealth into nepotism, warfare, and architectural grandeur, mistaking magnificence for majesty. Yet beneath the pageantry, the spiritual foundation was eroding. Voices for reform arose—from men within the Church itself—but they were dismissed, censured, or burned.

I wanted to probe why an institution supposedly devoted to salvation could not save itself. The folly lay not in evil intent but in self-justifying blindness. The popes could rationalize every excess as serving divine glory. They fortified their positions with ceremony and lineage, convincing themselves that power validated purpose. When Martin Luther posted his theses in 1517, the Church had been warned for decades that indulgences, corruption, and clerical cynicism were corroding faith. Yet it reacted not with repentance but with suppression. By the time reform came, it came through rupture.

Here we meet one of folly’s enduring lessons: institutions rarely reform from within because self-interest, especially the collective self-interest of ruling bodies, transforms into doctrine. The cost of inaction becomes obvious only when catastrophe renders it unavoidable. The papal misrule produced more than a religious schism; it inaugurated centuries of division within Christendom. Folly, always more expensive than foresight, charges its price in the coin of human misery.
