I haven’t any right to criticise books, and I don’t do it except when I hate them. I often want to criticise Jane Austen, but her books madden me so that I can’t conceal my frenzy from the reader; and therefore I have to stop every time I begin. Everytime I read ‘Pride and Prejudice’ I want to dig her up and beat her over the skull with her own shin-bone.

- Samuel Clemens, in a letter to Joseph Twichell, 13 September 1898
