Learning is acquired by reading books, but the much more necessary learning, the knowledge of the world, is only to be acquired by reading men, and studying all the various facets of them. – Lord Chesterfield
Manners must adorn knowledge and smooth its way in the world, without them it is like a great rough diamond, very well in a closet by way of curiosity, and also for its intrinsic value; but most prized when polished. – Lord Chesterfield
