Cornelius Castoriadis was a Greek philosopher, economist and psychoanalyst. He is acknowledged as one of the most influential thinkers of the 21^st century.

He was born in Constantinople on March 11^th, 1922, and his family relocated to Athens soon after his birth.

Castoriadis was attracted by philosophy since his early age.

He studied law and economics at the Kapodistrian University of Athens.

In 1937, during the Metaxas Regime, he joined the Athenian Communist Youth and later moved to the Communist Party of Greece only to leave one year later after having formed a youth group against the political orientation of the party. In 1943, he joined the trotskyist group of Spyros Stinas.

In 1944, he authored his early texts on social science and Marx Weber, which he later published in the Archive of Sociology and Ethics magazine.

During December 1945, he embarked on the ship Mataroa and fled Athens to relocate to Paris.

In Paris, he completed his studies and continued to write, signing his works with several aliases before receiving the French citizenship.

Besides working as a psychoanalyst, he had also been working as an economist with the Organization for Economic Co-operation and Development until 1970. In 1979, Castoriadis was elected principal of École des Hautes Études en Sciences Sociales.

He received honourary doctorates from Panteion University in 1989 and from Democritus University of Thrace in 1993. Cornelius Castoriadis died on December 26^th, 1997, at the age of 75.
