“I have received your new book against the human race, and thank you for it. Never was such a cleverness used in the design of making us all stupid. One longs, in reading your book, to walk on all fours. But as I have lost that habit for more than sixty years, I feel unhappily the impossibility of resuming it. Nor can I embark in search of the savages of Canada, because the maladies to which I am condemned render a European surgeon necessary to me; because war is going on in those regions; and because the example of our actions has made the savages nearly as bad as ourselves. [in response to Rousseau's "The Social Contract"]”

“I have wanted to kill myself a hundred times, but somehow I am still in love with life. This ridiculous weakness is perhaps one of our more stupid melancholy propensities, for is there anything more stupid than to be eager to go on carrying a burden which one would gladly throw away, to loathe one’s very being and yet to hold it fast, to fondle the snake that devours us until it has eaten our hearts away?”

“You despise books; you whose lives are absorbed in the vanities of ambition, the pursuit of pleasure or indolence; but remember that all the known world, excepting only savage nations, is governed by books.”

“I know many books which have bored their readers, but I know of none which has done real evil.”

“I doubt if I shall ever have time to read the book again -- there are too many new ones coming out all the time which I want to read. Yet an old book has something for me which no new book can ever have -- for at every reading the memories and atmosphere of other readings come back and I am reading old years as well as an old book.”

“I took delight in hurling books across the room if I knew I would not be reading the second chapter. Then I’d go and pick them up again, because they are books, after all, and we are not savages.”

“I have no more than twenty acres of ground," he replied, "the whole of which I cultivate myself with the help of my children; and our labor keeps off from us the three great evils - boredom, vice, and want.”
