Jean-Paul Sartre IQ

Jean-Paul Sartre was born in Paris in 1905 and raised partly by his grandfather, a German teacher. He studied at the elite École Normale Supérieure, where he met Simone de Beauvoir, and came first in the 1929 agrégation in philosophy on his second attempt. He was a prisoner of war in 1940 and 1941. Being and Nothingness (1943) made him the leading existentialist. He wrote novels and plays, became a public activist and refused the 1964 Nobel Prize. He died in 1980.

No figure exists. LifeScore lists about 150 as an editorial marker, range 135 to 165. It rests on his first place in the 1929 agrégation, a vast output in philosophy, fiction and drama and his leadership of a major movement.

Sartre's summary of existentialism: humans are not born with a fixed nature or purpose. We exist first and then define ourselves by our choices, so we are "condemned to be free" and fully responsible for what we become.

He said he always declined official honours because a writer should not allow himself to be turned into an institution, and that accepting would lend his name to the prize's politics. He is one of the few people to refuse it voluntarily.

They met as students in 1929 and remained partners for 51 years, never marrying or living together, and allowing each other other relationships. They read and criticised each other's work closely, and scholars now argue that Beauvoir shaped his philosophy more than was once recognised.

Sartre built philosophy from concrete scenes: a waiter playing at being a waiter, a man caught looking through a keyhole. Drawing abstract structures out of everyday examples is a strong form of analogical reasoning.

What supports it

• He came first in the 1929 agrégation in philosophy.
• He was awarded the 1964 Nobel Prize in Literature.
• He published dozens of books across genres.

What it cannot prove

• His politics, including support for Stalinist and Maoist positions, are widely criticised.
• Influence in philosophy depends on timing, institutions and readers as well as on the power of the reasoning.
• An editorial marker is a comparison aid built from achievement, not a measurement, and two careful readers could place it ten points apart.

Jean-Paul Sartre's IQ is represented here by a retrospective estimate of 150, not a verified test result. Jean-Paul Sartre is best known for exceptional abstract argument. The useful question is what the surviving evidence shows, not whether a precise modern score can be recovered.

Restless, prolific and political. A writer who worked on amphetamines and argued with everyone.

The dominant archetype here is The Engaged Intellectual. This archetype shapes decision patterns: what feels natural, what creates friction, and what blind spots tend to emerge.

Estimated IQ is 150. This is a rough estimate based on documented accomplishments and contemporary accounts, not a literal measurement.

About 50,000 people followed his funeral procession through Paris in 1980.
