The habit which many have got into must be as far as possible corrected; those, I mean, who while they fight strenuously against the baser pleasures, yet still go on hunting for pleasure in the shape of worldly honour and positions which will gratify their love of power. They act like some domestic who longed for liberty, but instead of exerting himself to get away from slavery proceeded only to change his masters, and thought liberty consisted in that change. But all alike are slaves, even though they should not all go on being ruled by the same masters, as long as a dominion of any sort, with power to enforce it, is set over them.
