Our virtues are voluntary (and in fact we are in a sense ourselves partly the cause of our moral dispositions, and it is our having a certain character that makes us set up an end of a certain kind), it follows that our vices are voluntary also; they are voluntary in the same manner as our virtues.
Vice is a monster of so frightful mien As to be hated needs but to be seen; Yet seen too oft, familiar with her face, We first endure, then pity, then embrace.
