Nimium amator ingenii sui

From a letter of Laurence Sterne’s of Jan 1, 1760, responding to an unknown addressee’s cautionary remarks about Tristram Shandy.  There are three significantly enough different versions of this letter that the editors of the Florida Edition printed them separately, numbering each 35A, B, and C.  I’m pulling from A.
