“There is no reality except in action. Man is nothing else than his plan; he exists only to the extent that he fulfills himself; he is therefore nothing else than the ensemble of his acts, nothing else than his life.”

French philosopher, political activist, and writer

Jean-Paul Sartre was a French philosopher, political activist, and writer. He was a leading figure in 20th-century French philosophy and Marxism, and one of the central thinkers associated with existentialism. He also supported Libertarian Marxism, and his work went on to shape sociology, critical theory, post-colonial theory, and literary studies. In 1964, he received the Nobel Prize in Literature, though he tried to refuse it, saying that he usually declined official honors and that a writer should not become an institution.
