And odious Pride a Million more;
Envy it self, and Vanity,

The first Rudiments of Morality, broach'd by skilful Politicians, to render Men useful to each other as well as tractable, were chiefly contrived that the Ambitious might reap the more Benefit from, and govern vast Numbers of them with the greater Ease and Security.
