Born Edgar Nahoum, of Sephardic origin, he adopted the pseudonym Morin during World War II to join the French Resistance. His long life, spanning over a century, was marked by a constant commitment to freedom and a critical view of authoritarian regimes.

His youth was influenced by historical events such as the Spanish Civil War, where he provided humanitarian aid to the Durruti Column. Later, he broke ties with the French Communist Party due to disagreements with Stalin's line and denounced the crimes of the KGB, demonstrating a continuous pursuit of intellectual autonomy.

Morin was a staunch advocate for multidisciplinary knowledge and hope as a way to prevent global catastrophes. His philosophy, described as "useful," connected street life with emblematic Parisian intellectual spaces like the Café de Flore.

Europe mourns the loss of one of its great intellectuals, a witness to two turbulent centuries. Morin held a special affection for Barcelona, describing it as an "open city, happy with its Catalan culture, its Spanish culture, and the Latin cultures that are settled in it."

His magnum opus, The Method, comprises six volumes, and he was commissioned by UNESCO to write The Seven Skills Necessary for the Education of the Future. In his last book, he reflected on the lessons of history, comparing the French Revolution to the convocation of the Estates-General.

French President Emmanuel Macron highlighted that Morin "was humanism embodied," recalling his kindness, curiosity, and universal spirit.
