"I would pass some of my time in reading, and the rest in the company of people of sense and learning, and chiefly those above me; and I would frequent the mixed companies of men and women of fashion, which, though often frivolous, yet they unbend and refresh the mind, not uselessly, because they certainly polish and soften the manners."
— Stanhope, Philip Dormer, fourth earl of Chesterfield (1694-1773)
