Twain, Mark (Samuel Langhorne Clemens) (1835–1910)
Apparently the only connection Mark Twain has with the quotation is the following passage in Mark Twain’s Autobiography, Volume I, Berkeley, Los Angeles and London: University of California Press 2010, p. 228 (this particular passage was dictated in Florence in 1904):
I was deducing from the above that I have been slowing down steadily in these thirty-six years, but I perceive that my statistics have a defect: three thousand words in the spring of 1868, when I was working seven or eight or nine hours at a sitting, has little or no advantage over the sitting of to-day, covering half the time and producing half the output. Figures often beguile me, particularly when I have the arranging of them myself; in which case the remark attributed to Disraeli would often apply with justice and force:
“There are three kinds of lies: lies, damned lies, and statistics.”
The article by Courtney quoted above is the published version of a speech on proportional representation (which was also Baines’ subject) that was given in August 1895 in New York State, which may help explain how Mark Twain came to know the phrase. On the other hand the passages in The Times and The New York Times referred to above may indicate other reasons why he knew the phrase.
