Philip Dormer Stanhope, Earl of Chesterfield 
Letters to His Son on the Art of Becoming a Man of the World and a Gentleman, 1746-47 [EPUB ebook] 

pub One.info present you this new edition. The proud Lord Chesterfield would have turned in his grave had he known that he was to go down to posterity as a teacher and preacher of the gospel of not grace, but- "the graces, the graces, the graces. " Natural gifts, social status, open opportunities, and his ambition, all conspired to destine him for high statesmanship. If anything was lacking in his qualifications, he had the pluck and good sense to work hard and persistently until the deficiency was made up. Something remained lacking, and not all his consummate mastery of arts could conceal that conspicuous want, — the want of heart.
