> I disapprove of what you say, but will defend to the death your right to say it” -Voltaire
I also just want to elucidate this quote a bit in case you didn't know.
Voltaire did not actually write these exact words. The line is a summary of his views on freedom of speech and thought, and it was penned by Evelyn Beatrice Hall in her 1906 biography of Voltaire titled "The Friends of Voltaire." Hall wrote this phrase to encapsulate Voltaire's beliefs on the subject.
Given that Voltaire himself did not say these exact words, there is no specific context in which he was addressing someone or some particular statement he disagreed with.
Voltaire was a man of the Enlightenment, which prioritized reason, evidence, and logical argumentation. He would likely have opposed the deliberate spread of falsehoods and deceit. However, he would also probably have advocated for the right of people to express even flawed arguments, as challenging such arguments through reason and debate is foundational to Enlightenment values.
But when it comes to personal attacks, slander, deceit, and hate speech, he would have not been so tolerant, because the subtext is when he speaks of "speech" he means engaging in an enlightened conversation using reason, evidence, and logical argumentation. It's okay to have flawed logic, evidence or reasoning, but he was fighting the powers at be of his time, and those were using deceit, irrational and illogical fallacies, appeals to emotions, forced censorship and the like to push falsehoods. The values of the enlightenment were about working towards accurate truth seeking.
