Via a commenter at Schneiderman:
I think Voltaire should have a say in this matter, just as he did when that lunatic, Rousseau, sent him a copy of the "Discourse of the Origin of Inequality."
"I have received, sir, your new book against the human race, and I thank you for it. You will please people by your manner of telling them the truth about themselves, but you will not alter them. The horrors of that human society--from which in our feebleness and ignorance we expect so many consolations--have never been painted in more striking colors: 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 about all fours. Since, 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: I leave this natural habit to those more fit for it than are you and I. Nor can I set sail to discover the aborigines of Canada, in the first place because my ill-health ties me to the side of the greatest doctor [1] in Europe, and I should not find the same professional assistance among the Missouris: and secondly because war is going on in that country, and the example of the civilized nations has made the barbarians almost as wicked as we are ourselves. I must confine myself to being a peaceful savage in the retreat I have chosen--close to your country, where you yourself should be."
