Six Minds That Shaped Modern Thought: From Descartes's Dutch Stove to Derrida's Algerian Beach, an Illustrated History of How French Thinkers Have Reinvented Philosophy — and Often the World With It
1596–1650 • Cogito, Dualism, and the Geometry of Light
Born in La Haye en Touraine (now renamed Descartes), educated by Jesuits at La Flèche, briefly a soldier, René Descartes spent his most productive years in the Dutch Republic. There, on November 10, 1619, he had three vivid dreams that he believed revealed his life's mission: to found a unified philosophy on indubitable foundations. From the Cogito to the wax argument to mind-body dualism, Descartes inaugurated modern philosophy — and modern mathematics with his coordinate geometry.
1596–1650 • French Catholic; mostly resident in the Netherlands
Sickly child whose mother died when he was an infant; raised by his maternal grandmother. Trained at La Flèche, then took a law degree at Poitiers. Volunteered as a gentleman soldier under Maurice of Nassau and Maximilian of Bavaria. Settled in Holland from 1628, moving 24 times in 21 years for solitude. Died of pneumonia in Stockholm in February 1650, summoned by Queen Christina to give 5am philosophy lectures.
Friar and clearinghouse of the Republic of Letters. Solicited the Objections to the Meditations and circulated Descartes's work across Europe.
Daughter of the deposed Winter King. Sharpest critic of Descartes's mind-body interaction. Later Abbess of Herford.
Provencal priest and atomist. Wrote the Fifth Set of Objections, defending an Epicurean view against Cartesian innate ideas.
Brilliant, eccentric Lutheran-then-Catholic queen of Sweden. Inadvertently caused Descartes's death by demanding 5am lessons.
Descartes is the first — the great founder against whom every later French thinker measures themselves. Voltaire admired his logic; Rousseau preferred his sentiment. Sartre's existential subject is a Cogito stripped of God. Foucault and Derrida defined themselves against the "Cartesian subject." French philosophy is, in some sense, an extended dialogue with Descartes.
1694–1778 • Polemicist, Playwright, Crusader for Tolerance
François-Marie Arouet, who took the pen name Voltaire in 1718, was the most famous and most feared writer in 18th-century Europe. Twice imprisoned in the Bastille, exiled to England, banished from Paris, and finally welcomed home in triumph at 83 to die six weeks later. He wrote roughly 20,000 letters and 2,000 books and pamphlets, fought tirelessly against religious fanaticism — especially after the 1762 judicial murder of Jean Calas in Toulouse — and gave the Enlightenment its rallying cry.
1694–1778 • Paris, London, Geneva, Ferney
Son of a notary in the Treasury. Educated by Jesuits at the Collège Louis-le-Grand. Ferocious wit landed him in the Bastille at 23 for libelling the Regent. Made his fortune at 35 by cornering a flawed Paris lottery, then multiplied it by speculation. Lived from 1758 at Ferney, on the Swiss border, just close enough for fast escape if Paris ordered him arrested again.
Voltaire's lover and intellectual partner for 16 years. French translator of Newton's Principia (still in use today). Died in childbirth at 42.
Editor of the Encyclopédie. Voltaire's friend and rival. Imprisoned at Vincennes 1749. Spent 25 years on the great encyclopedia.
King of Prussia and amateur philosopher. Voltaire's host at Sanssouci 1750–53; the friendship ended in mutual fury.
Innocent Toulouse Protestant broken on the wheel. His rehabilitation made Voltaire France's first modern human-rights champion.
Where Descartes built systems and Rousseau mistrusted civilization, Voltaire was the supreme polemicist — less a system-builder than a tactical genius of public argument. Sartre, two centuries later, would consciously emulate Voltaire as the engaged writer; Foucault would diagnose the Voltairean Enlightenment as itself a regime of power.
1712–1778 • Social Contract, Emile, and the General Will
A Genevan watchmaker's son who ran away at 16, Jean-Jacques Rousseau lived as a vagabond, secretary, music teacher, and finally as the most controversial writer in Europe. His three masterpieces of 1761–62 — Julie, or the New Heloise; The Social Contract; and Emile, or On Education — were burned by parliaments and bishops, drove him into exile, and arguably did more to prepare the French Revolution than any other body of work. He died eleven years before the storming of the Bastille.
1712–1778 • Genevan exile, Parisian celebrity, paranoid wanderer
Mother died at his birth; father abandoned him at 10. Apprenticed to an engraver, he ran away at 16 and converted to Catholicism in Turin to survive. Lived for years with the older Madame de Warens, his "Mama." Sired five children with the seamstress Thérèse Levasseur and consigned all to the foundling hospital. The dissonance with the educational ideals of Emile was used against him for the rest of his life.
Rousseau's "Maman" from age 16. He lived with her for years at Les Charmettes; their relationship became sexual when he was about 21.
Illiterate Paris seamstress; Rousseau's lifelong companion from 1745. Mother of his five abandoned children.
Scottish philosopher who sheltered Rousseau in England 1766–67. Their break was bitter and very public.
The Incorruptible Jacobin claimed to follow Rousseau's general will literally. The Terror was Rousseau's most disturbing legacy.
Where Descartes founded modern philosophy on reason, Rousseau founded Romantic philosophy on feeling and conscience. He attacked Voltaire's salon urbanity; Voltaire returned the compliment. Sartre would inherit Rousseau's ideal of authenticity. Foucault, in Discipline and Punish, treated Rousseau's social contract as itself a technology of power.
1905–1980 • Being and Nothingness, Bad Faith, and the Engaged Intellectual
Born in Paris in 1905, half-orphaned at 15 months, Jean-Paul Sartre became France's most famous public intellectual of the 20th century. POW in 1940, escaped through medical discharge, joined the Resistance, and emerged after the Liberation as the high priest of Existentialism. With Simone de Beauvoir — his lifelong, never-married companion — he made the Café de Flore the headquarters of post-war thought. He refused the Nobel Prize in 1964, the only laureate ever to do so voluntarily.
1905–1980 • Paris; École Normale Supérieure; Resistance; activist
Father, a naval officer, died when Sartre was 15 months old; raised by his German-teacher grandfather Karl Schweitzer (Albert's uncle). Wall-eyed from age three. Met Simone de Beauvoir at the École Normale in 1929; they signed a "two-year pact" of openness that became a lifelong partnership. Captured at Padoux in June 1940; read Heidegger in the prison camp. Active in the Resistance from 1941.
The Second Sex (1949). Sartre's lifelong companion. They are buried together at Montparnasse Cemetery.
Phenomenology of Perception (1945). Co-edited Les Temps Modernes with Sartre. Broke politically over the Soviet camps in 1953.
Sartre's friend and rival. They broke spectacularly in 1952 over Camus's L'Homme révolté. Camus died in a car crash before reconciliation.
Martiniquan psychiatrist; The Wretched of the Earth (1961). Sartre's preface to that book extended existentialism to anti-colonial revolution.
Sartre's free, choosing subject is descended from Descartes's Cogito but stripped of God and substance. He shared Voltaire's role as engaged public intellectual but with greater theoretical depth. Foucault and Derrida defined themselves against Sartrean humanism: their structures, languages, and powers leave no room for the heroic existential chooser.
1926–1984 • Madness, Discipline, Sexuality, Biopower
Born in Poitiers to a surgeon's family, Paul-Michel Foucault studied at the École Normale Supérieure under Louis Althusser. His "archaeologies" of madness, the clinic, and the human sciences were transformed in the 1970s into "genealogies" of punishment, discipline, and sexuality. From his Collège de France chair (1970–84), Foucault developed the most influential analysis of modern power in the 20th century — one in which power is everywhere, productive and repressive, and operates through knowledge itself.
1926–1984 • Paris; ENS; Tunisia; California; Iran
Suicidal student at the ENS; came out as gay (still a difficult identity in France). Studied with Althusser, Hyppolite, and Canguilhem. Worked at the Maison de France in Uppsala, then Warsaw, then Hamburg before returning to France. Taught at Tunis during the 1968 student uprisings. Elected to the Collège de France in 1970, where his lecture courses became Paris's hottest tickets. Died of AIDS-related illness in 1984.
Foucault's ENS teacher. Marxist structuralist; ideological state apparatuses. Strangled his wife Hélène in 1980 during a psychotic episode.
Philosopher of biology and history of science. Foucault's doctoral supervisor. The Normal and the Pathological (1943).
Collège de France sociologist, contemporary and rival. Habitus, cultural capital, symbolic violence. The other great post-Sartre French theorist.
Foucault's partner from 1963 until his death. Founded AIDES, France's leading AIDS NGO, in Foucault's memory in 1984.
Foucault attacked the Sartrean subject — the autonomous, choosing self — as itself a historical product of disciplinary power. He preserved Voltaire's critical posture but turned it against the Enlightenment's own categories. Where Descartes founded a unified rational self, Foucault traced how that self was constructed, regulated, and might yet be refused.
1930–2004 • Différance, Trace, and the Closure of Metaphysics
Born to a Sephardic Jewish family in El Biar, Algeria, expelled from school in 1942 by Vichy laws, Jacques Derrida arrived at the École Normale Supérieure in 1952 and proceeded over five decades to dismantle Western philosophy's deepest oppositions. In a 1966 lecture at Johns Hopkins, he announced the end of structuralism and the beginning of a new method: deconstruction, the patient unraveling of every text's hidden hierarchies. By the 1990s, "deconstruct" had entered ordinary English as a verb.
1930–2004 • El Biar, Paris, Yale, UC Irvine
Expelled from his Algiers lycée in 1942 under Vichy anti-Jewish laws; readmitted in 1943. Failed his first attempt at the École Normale (1949), entered in 1952. Met Bourdieu, Foucault, and Althusser. Failed his agrégation in 1955 on his first attempt; never forgot the humiliation. Married Marguerite Aucouturier in 1957. Taught at the ENS (1964–84), the École des Hautes Études (1984–2003), Yale (1975–86), and UC Irvine (1986–2004).
Yale literary theorist; Derrida's closest American ally. Posthumous discovery of his 1940s Belgian collaborationist journalism caused enormous scandal in 1987.
Lithuanian-French phenomenologist of the face and ethics. Derrida's "Violence and Metaphysics" (1964) is the great extended dialogue with him.
Columbia critic. Translated Of Grammatology in 1976; her preface to it is more cited than the book itself in some quarters. Founder of postcolonial theory.
Frankfurt School critical theorist. Long opposed Derrida's deconstruction as performative contradiction; reconciled with Derrida 2001–03 over Iraq War opposition.
Where Descartes sought certainty in the Cogito, Derrida traced the deferral of all presence; where Sartre asserted the engaged subject, Derrida found subjects constituted in writing they cannot master; where Foucault analyzed discourse, Derrida read texts. Yet Derrida is unmistakably in the line: a French philosopher in love with the resources of a French sentence.

Five of the six worked in or around Paris; Descartes wrote in the Netherlands and Sweden but was Paris-trained. The École Normale Supérieure produced Sartre, Foucault, and Derrida directly. The Collège de France crowned both Foucault and Bourdieu. Paris is not just where French philosophy happens; it is, for two centuries, where world philosophy happens.
French philosophy is unusual in expecting its leading thinkers to engage public life. Voltaire's Calas affair set the template; Zola's J'accuse continued it; Sartre and Foucault perfected it. Even Derrida, the supposed apolitical theorist, intervened on apartheid, the death penalty, and the Iraq war.
Voltaire (Bastille × 2; lifelong exile), Rousseau (warrants for arrest; persecution mania), Sartre (POW; nearly arrested 1968), Foucault (police violence in Tunis), Derrida (Vichy expulsion; jailed in Prague 1981). The suspicion that French philosophy regards itself as legitimate opposition to power is largely earned.
Voltaire-du Châtelet, Rousseau-Thérèse, Sartre-Beauvoir, Foucault-Defert, Derrida-Marguerite. Equally, the famous quarrels: Voltaire vs. Rousseau, Sartre vs. Camus, Foucault vs. Sartre, Habermas vs. Derrida. French philosophy is a family business with explosive divorces.
Each generation defines itself against its predecessor. Descartes vs. Scholasticism. Voltaire vs. inherited religion. Rousseau vs. Voltairean civilization. Sartre vs. bourgeois bad faith. Foucault vs. Sartrean subject. Derrida vs. structuralist closure. The tradition advances by negation.
French philosophy treats style as inseparable from argument. Voltaire's wit, Rousseau's lyricism, Sartre's heavy phenomenological prose, Foucault's archive-density, Derrida's puns and palimpsests — the form carries the content. Translation is famously impossible; the books are themselves performances.
