He died at 83, and is buried at the Pantheon in Paris.

5. Simone de Beauvoir (1908 – 1986) 

French writer and female activist Simone de Beauvoir did not consider herself a philosopher, but her writings expounded significantly on both feminist theory and feminist existentialism.

One is not born, but rather becomes, a woman.

Simone de Beauvoir

France would grant women the right to vote during her lifetime in 1946, due to the advocacy work of writers and philosophers like her.

One of her most famous books was the 1949 treatise The Second Sex, a detailed analysis of women’s oppression and contemporary feminism. She would win France’s top prize for writers, the Prix Goncourt in 1954.

6. Jules Michelet (1798 – 1874)

French historian and philosopher Jules Michelet is credited with being the first European historian to use and define the word Renaissance (‘Re-birth’ in French) that represented a drastic break from the Middle Ages.

In philosophy, he is celebrated for his logical solution to the problem of universals via nominalismconceptualism and intent in ethics.

The beginning of wisdom is found in doubting; by doubting we come to the question, and by seeking we may come upon the truth.

Peter Abelard

However, in popular culture, he is best known for his passionate and tragic love affair with his brilliant student and eventual wife, Héloïse d’Argenteuil. 

8. Héloïse d’Argenteuil (1092 – 1164)

It is said that at the time Heloise met Abelard, he was surrounded by students drawn from all countries by the fame of his teaching.  Héloïse d’Argenteuil means “Héloise of Argenteuil”, as her official last name which is unknown. 

Abelard was already famous when they met, and they quickly fell in love. Their love is evidenced by numerous love letters between the two, discussing love and philosophy, not as student and teacher, but as equals.

She was known to be an intelligent writer, scholar, and philosopher herself. Their letters are considered a foundation of French and European literature and primary inspiration for the practice of courtly love.

No one’s real worth is measured by his property or power: Fortune belongs to one category of things and virtue to another.

Héloïse d’Argenteuil

However, she was the ward of her maternal uncle Canon Fulbert of Notre Dame who did not approve of their illicit relationship which also resulted in a child.

They married secretly to try to appease Fulbert (married philosophers were not a thing in the 12th century), but in a tragic misunderstanding, Fulbert sent a band of men to defend her honor by castrating Abelard.

After the event, both Abelard and Heloise retired to separate monestaries, with Heloise becoming a nun and eventually elevated to the rank and political power of the female version of a bishop.

It is unclear how their letters came to be preserved and published, but their story has remained legendary. After their deaths, their bones were moved multiple times to be placed together. A statue of Abelard was even placed among the statues carved into the exterior of the Louvre.

In 1817 they were reburied in Père Lachaise cemetery in the 20th arrondissement of Paris, having considerably contributed to the popularity of that cemetery. By tradition, lovers or lovelorn singletons leave letters at the crypt even today, in tribute or in hope of finding true love.

9. Michel de Montaigne (1533 – 1592)

Known as Lord of Montaigne, he was one of the most significant philosophers of the French Renaissance.

Lend yourself to others, but give yourself to yourself.

Michel de Montaigne

One of his most famous books is the massive volume Essais which contains some of the most influential essays ever written. It is said that he had a direct influence on European writers from Francis Bacon, René Descartes, Blaise Pascal, Voltaire, Jean-Jacques Rousseau, Karl Marx, Sigmund Freud, and possibly even on the later works of William Shakespeare.

Michel Foucault

When people can not change things, they change the words.

Jean Jaures

However, it was his defence of socialism that really raised his profile and why he is celebrated by the French Left even today. Many benefits that the French have today, such as employee working hours, etc. are all due to his passionate advocacy of workers’ rights and the rights of protestors.

According to some historians, his plan had been to expose then French President Poincaré’s secret deal with Russia to the Germans. With the President pushed out of the way, he believed that France and Germany would have reconciled, and he would have been able to push his reforms.

A great orator, who had much support on the left, his death on July 31, 1914 sent shockwaves through the country and destabilized the government of the day. France would invade Alsace to enter WW1 and fight against Germany on August 7, 1914.
