Translation
Philip Mairet, Existentialism and Humanism (Methuen, 1948)
That is what I mean when I say that man is condemned to be free. Condemned, because he did not create himself, yet is nevertheless at liberty, and from the moment that he is thrown into this world he is responsible for everything he does.
Philip Mairet’s 1948 English translation of the 1945 lecture. The phrase “man is condemned to be free” is Sartre’s own; the wording after it is Mairet’s rendering of the French.
The French original — “l’homme est condamné à être libre” — is one of the two aphorisms the lecture is remembered for, alongside “existence precedes essence,” per French Wikipedia.
The exact English phrase “man is condemned to be free” appears verbatim in the Philip Mairet translation hosted at the Marxists Internet Archive.
The line is genuinely Sartre’s but is frequently mis-sourced to Being and Nothingness (1943), where a related “I am condemned to be free” appears — see the Wikiquote entry.
The lecture was first published in French in 1946 and the Philip Mairet English translation in 1948 — both after 1930, so the work and this translation are in copyright in the United States. Sartre died in 1980; rights rest with his estate / Éditions Gallimard, and with the translation’s publisher for the English wording.
Fact-check
The attribution is right — but the source and wording often aren’t
The line is authentically Sartre’s, so this is not a case of a fake quote. Two smaller errors do travel with it: a wrong source and a paraphrased longer form.
✕
Wrong sourceBeing and Nothingness (1943) mis-sourced
The phrase is regularly cited as coming from Being and Nothingness. The idea of being “condemned” to freedom does appear there (“I am condemned to be free”), but the exact famous sentence “man is condemned to be free” comes from the 1945 lecture Existentialism Is a Humanism, per the Wikiquote record and the lecture text.
✕
Paraphrased tailThe popular longer version reworded
The widely shared form — “Man is condemned to be free; because once thrown into the world, he is responsible for everything he does” — is a condensed, looser rendering. Mairet’s actual 1948 text reads “Condemned, because he did not create himself, yet is nevertheless at liberty, and from the moment that he is thrown into this world he is responsible for everything he does.” The shortened version circulates on sites like Goodreads without a source.
✓Sartre really said it — in his lecture Existentialism Is a Humanism (1945, published 1946), confirmed word-for-word in the Mairet translation.
Context
Why it mattered
Sartre delivered the lecture in October 1945 to defend existentialism against critics who called it gloomy and amoral. “Man is condemned to be free” compresses his central claim: with no God and no fixed human nature to fall back on, people cannot excuse their choices — they are wholly responsible for what they make of themselves.
“Condemned” is deliberately paradoxical: freedom here is not a gift but a burden nobody chose. It became one of the most quoted phrases of twentieth-century philosophy.
Man did not create himself, yet is nevertheless at liberty — and so responsible for everything he does.
