For information sake

"...Aretino's dialogues are of additional literary interest for serving as the model for such works as L'Escole des Filles (1655), which appeared in English as The School of Venus (1688). It was the French version of this "novel" - consisting mainly of a discussion of sexual matters by two girls, Fanchon and Susanne - that was purchased on February 8, 1668, by His Majesty' Secretary of Naval Affairs, one Samuel Pepys. He characterized it as "the most bawdy, lewd book that I ever saw," and for this reason procured it "in plain binding, avoiding the buying of it better bound because I resolve, as soon as I have read it, to burn it." The next night, after consuming "a mighty good store of wine," he retreated to the privacy of his chamber, where he read the book "for information sake," then proceeded with the burning, "that it might not be among my books to my shame."
