'Affectation is never more tiresome and ridiculous than in a letter. Madame de Sevigne was the best letter-writer that ever existed. I would rank Swift and Lord Chesterfield next. Voltaire to me is charming; but then I suspect he studied his epistles, as Lord Orford certainly did, and so had little merit. Heloise wrote beautifully in the old time; but we are very poor, both in England and Scotland, as to such matters'.
