Context

“In the courts of princes, in the drawing-rooms of the great, where success and preferment depend, not upon the esteem of intelligent and well-informed equals, but upon the fanciful and foolish favour of ignorant, presumptuous, and proud superiors; flattery and falsehood too often prevail over merit and abilities. In such societies the abilities to please, are more regarded than the abilities to serve. In quiet and peaceable times, when the storm is at a distance, the prince, or great man, wishes only to be amused, and is even apt to fancy that he has scarce any occasion for the service of any body, or that those who amuse him are sufficiently able to serve him.” source
