“When Rousseau sent to Voltaire his Discourse on the Origin of Inequality, with its arguments against civilization...Voltaire replied: "I have received, sir, you new book against the human species, and I thank you for it... No one has ever been so witty as you are in trying to turn us into brutes; to read your book makes one long to go on all fours. As, however it is now some sixty years since I gave up the practice, I feel that it is unfortunately impossible for me to resume it." (Chapter on Voltaire, p.247/543)”
