In your quotes by author section, I was curious to see if you had
"I may disagree with what you have to say, but I shall defend, to the death, your right to say it" attributed to Voltaire, and there it is.
First, I thought there might be mention of the fact that "Voltaire" is a pen name for Francois Marie Arouet. He adopted the pen name while in prison writing "Oedipe." See
Second, the quote in question is a 20th century fabrication that was associated with Voltaire and has stuck to him like cement.
Some exerpts from the noted webpage:
"I disapprove of what you say, but I will defend to the death your right to say it" is widely attributed to Voltaire, but cannot be found in his writings. With good reason. The phrase was invented by a later author as an epitome of his attitude. It appeared in The Friends of Voltaire (1906), written by Evelyn Beatrice Hall under the pseudonym S[tephen] G. Tallentyre"
...The men who had hated [the book], and had not particularly loved Helvetius, flocked round him now. Voltaire forgave him all injuries, intentional or unintentional. 'What a fuss about an omelette!' he had exclaimed when he heard of the burning. How abominably unjust to persecute a man for such an airy trifle as that! 'I disapprove of what you say, but I will defend to the death your right to say it,' was his attitude now. But he soon came, as a Voltaire would come, to swearing that there was no more materialism in 'On the Mind' than in Locke, and a thousand more daring things in 'The Spirit of Laws.'
Hall herself claimed later that she had been paraphrasing Voltaire's words in his Essay on Tolerance:
"Think for yourselves and let others enjoy the privilege to do so too."
Hall died in 1919.
