Who really said it

I disapprove of what you say, but I will defend to the death your right to say it

Q: Did Voltaire say "I disapprove of what you say, but I will defend to the death your right to say it"?

No. Voltaire never wrote or spoke these words. The sentence was composed by his English biographer Evelyn Beatrice Hall in The Friends of Voltaire (1906) as her own summary of his attitude toward the censorship of Claude-Adrien Helvétius's book De l'esprit. As Quote Investigator documents, Hall later admitted the line was "my own expression," and it has never been located in any of Voltaire's works.

Quote Investigator: the full origin trail

How we traced it

Quote Investigator traces the earliest appearance to Hall’s 1906 The Friends of Voltaire, concluding “many researchers have attempted to find the quotation in the works of Voltaire, but it has never been located” — see their full investigation ↗.
Hall herself disowned the attribution: in a 1919 volume she called it merely a “Voltairean principle,” and in a 1939 letter (published in Modern Language Notes) she wrote that the phrase “is my own expression and should not have been put in inverted commas” — documented by Quote Investigator ↗.
Wikipedia’s biography of Hall ↗ confirms she wrote the line in The Friends of Voltaire (1906) to illustrate Voltaire’s beliefs, and that it is “sometimes misattributed to Voltaire himself.”

Public domain

The wording is Evelyn Beatrice Hall’s, first published in The Friends of Voltaire (London, 1906). A work published before 1931 is in the public domain in the United States, so the sentence itself is free to reproduce — only the false ‘Voltaire’ label is the problem.

Fact-check

The most famous quote Voltaire never said

This is one of the internet’s canonical fake attributions. The sentiment is genuinely Voltairean, but the sentence is a 20th-century biographer’s invention that got pinned back onto her subject.

Voltaire Misattributed

Voltaire (1694–1778) never wrote or spoke this line in any known work, letter, or recorded remark. As Quote Investigator ↗ notes, it “has never been located” in his writings despite extensive searching.

Evelyn Beatrice Hall True author

Hall coined the sentence in The Friends of Voltaire (1906) as a summary of his attitude, and later stated the words were “my own expression,” per her biography ↗.

The idea reflects Voltaire’s spirit; the famous words are Evelyn Beatrice Hall’s 1906 paraphrase — a fact she herself confirmed, as documented by Quote Investigator ↗.

Context

Why the mix-up happened

Hall was distilling a real episode: in 1758 the philosopher Claude-Adrien Helvétius published De l’esprit, which was condemned and burned. Voltaire had little regard for the book, yet defended its author’s freedom to publish. Hall compressed that stance into a single memorable line — and because it sat inside a Voltaire biography, readers assumed the words were his own.

Her use of quotation marks in the 1906 text sealed the confusion. Hall spent years trying to correct the record, but the epigram was too good to un-stick, and it remains the most-cited ‘Voltaire’ quote he never uttered.

“The phrase … is my own expression and should not have been put in inverted commas.” — Hall, 1939

The true author

Evelyn Beatrice Hall

1868–1956 · English biographer · pen name ‘S. G. Tallentyre’

Evelyn Beatrice Hall was an English writer and biographer who published under the pen name S. G. Tallentyre. Her The Life of Voltaire (1903) and The Friends of Voltaire (1906) were popular Edwardian biographies. In the latter she coined the free-speech maxim as a distillation of Voltaire’s outlook — a line that would eclipse her own name and be handed back to her subject for over a century.
