Voltaire | I disapprove of what you say

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

Voltaire (François-Marie Arouet) | The quote is attributed to Voltaire, but was probably penned by Evelyn Beatrice Hall (pseudonym Stephen G. Tallentyre), who used it in her book The Friends of Voltaire (1906, archive.org) to characterize Voltaire's attitude towards Claude Adrien Helvétius.

"Ich bin zwar anderer Meinung als Sie, aber ich würde mein Leben dafür geben, dass Sie Ihre Meinung frei aussprechen dürfen."
