Tremendously influential philosopher (1711-1776) considered one of the most important figures in the history of Western philosophy. Exceedingly rare ALS, one page, 6.5 x 8.5, February 13, 1769. Letter to a London bookseller by the name of "Beckett," in full: "This will be delivered to you by Mon'r Prault, one of the most celebrated Booksellers of Paris, both for the Largeness of his Dealings, and the Probity and Integrity of his Conduct. I thought it might be useful to both of you to be acquainted with each other, and I therefore recommend him to you: And I doubt not, but in every thing, which you can do to serve and oblige him he will find you very ready & willing. In doing so, you will also confer a Favour on Sir." In very good to fine condition, with trimmed edges, a few tiny holes, and a repaired tear to the right edge.
