1533-1592 CE
What do I know? Study yourself, accept uncertainty, judge nothing hastily, and recognize that custom is mere habit mistaken for nature.
Born in 1533 at the family château near Bordeaux, son of a wealthy merchant family that had purchased nobility. His father, influenced by humanist ideas, gave him an extraordinary education. For his first years, he heard only Latin — servants were hired who spoke only Latin to the child, making it his native tongue. He learned Greek early and studied law, serving in the Bordeaux parlement (regional court) from 1557 to 1570.
During these years he met Étienne de La Boétie, forming the most important friendship of his life. Their bond was so intense that Montaigne later wrote, “If you press me to say why I loved him, I can say no more than because he was he, and I was I.” La Boétie died suddenly in 1563 at age thirty-two. Montaigne never recovered from the loss, claiming he was now only half alive. He began writing partly to fill the void.
In 1571, aged thirty-eight, he retired from public life to his château’s tower, converting the third floor into a library lined with about a thousand books. On the ceiling beams he inscribed Greek and Latin quotations about uncertainty, change, and death. There he began writing his Essays — literally “attempts” or “trials” of his judgment on various topics. He wrote about education, friendship, cannibals, liars, idleness, fear, smells, thumbs — anything that interested him. The method was revolutionary: honest self-examination, personal anecdotes, skeptical questioning, no systematic conclusions.
He published the first two books in 1580, then travelled through France, Germany, Switzerland, and Italy seeking cures for his kidney stones. In Rome he had an audience with Pope Gregory XIII. While travelling, he was elected mayor of Bordeaux, serving two terms (1581-1585) during the violent Wars of Religion. He navigated skillfully between Catholic and Protestant factions, maintaining neutrality and working for peace. He sheltered the Protestant King Henry of Navarre (later Henry IV) and negotiated with Catholic leaders, trusted by both sides for his integrity.
He continued revising and expanding the Essays until his death, preparing a third book and adding hundreds of passages to the earlier books. The final edition appeared posthumously in 1595, edited by his protégée Marie de Gournay. He died in 1592 at his château, having created a new literary form and a new way of philosophizing — personal, modest, skeptical, humane.
""Que sais-je?" (What do I know?)"
— Montaigne's motto, inscribed on a medal he wore. Captures his skeptical philosophy. We claim to know so much, but examining carefully, what do we really know with certainty? Very little. This isn't despair but humility. Recognizing our ignorance is the beginning of wisdom.
""I study myself more than any other subject. This is my metaphysics, this is my physics.""
— Montaigne's method: honest self-examination as path to understanding human nature. Rather than building abstract systems, he investigated himself — his thoughts, habits, preferences, inconsistencies. Since he was human, studying himself revealed universal patterns.
""Nothing is so firmly believed as what we least know.""
— On certainty's inverse relationship to knowledge. The less we actually know about something, the more confidently we pronounce on it. Real knowledge brings awareness of complexity and uncertainty. Ignorance breeds dogmatism.
Montaigne’s philosophy emerges from one question: Que sais-je? What do I know? Not a rhetorical question but genuine inquiry. Examining his beliefs carefully, stripping away custom, authority, and prejudice, what remains certain? Almost nothing. This isn’t nihilistic despair but liberating skepticism. If we don’t know with certainty, we should suspend judgment, remain open, tolerate difference, and avoid fanaticism. The Essays apply this method to everything. In Apology for Raymond Sebond, he systematically dismantles claims to certain knowledge. Human senses are limited and unreliable. Reason produces contradictory conclusions on every topic. Custom varies wildly across cultures, proving no moral absolute is self-evident. Animals show intelligence and virtue, undermining human claims to special status. Even our proudest achievements rest on shaky foundations. The conclusion isn’t that nothing is true but that we can’t know truth with the certainty we claim. This moderate skepticism aimed at practical wisdom, not theoretical impasse.
His method was self-examination. Rather than building systems from first principles, he studied himself relentlessly. How did he think? Why did he prefer certain things? What were his inconsistencies? By examining himself honestly, he revealed universal human patterns. The Essays jump from topic to topic, circle back, contradict themselves, change direction — mirroring how minds actually work rather than imposing artificial order. This wasn’t sloppiness but fidelity to experience. Thought doesn’t proceed geometrically. It associates, digresses, returns. The essay form captured this.
His cultural relativism was revolutionary. In Of Cannibals he described Brazilian indigenous people who eat enemies’ bodies. Europeans called them savages. Montaigne replied: which is more barbarous — eating dead enemies or torturing living heretics as we do in religious wars? Their cannibalism follows rational custom (honoring worthy opponents). Our torture follows irrational hatred. Neither is natural or inevitable — both are cultural practices. This relativism didn’t mean all practices are equally good but that none are self-evidently right. We must judge by effects and intentions, not by conformity to our customs.
His ethics emphasized self-knowledge and acceptance. We are changeable, inconsistent, subject to moods and circumstances. Accept this rather than pretending to be rational agents with fixed characters. We contain multitudes. Contradicting yourself isn’t moral failure but human reality. The goal isn’t consistency but authenticity — being true to what you actually are, not what philosophy or religion says you should be. This meant accepting bodily life. He wrote frankly about digestion, sexuality, aging, illness, and death. Philosophy that denies or transcends the body is fantasy. We’re embodied creatures. Wisdom requires accepting this condition.
His politics followed from his skepticism. The Wars of Religion arose from each side’s certainty about religious truth. Montaigne saw dogmatic certainty as the root of violence. If we admitted uncertainty, we’d tolerate difference. He advocated following established laws and customs while recognizing they’re arbitrary. Obey convention not because it’s right but because stability matters more than perfection. Reform gradually if needed, but avoid revolutionary upheaval born from certainty about better systems. This conservative skepticism frustrated revolutionaries and dogmatists but offered third path between rigid traditionalism and radical transformation.
