The gods are strange. It is not our vices only they make instruments to scourge us. They bring us to ruin through what in us is good, gentle, humane, loving.
Count all th' advantage prosperous Vice attains,
'Tis but what Virtue flies from and disdains:
And grant the bad what happiness they would,
One they must want--which is, to pass for good.
Sensuality, too, which used to show itself course, smiling, unmasked, and unmistakable, is now serious, analytic, and so burdened with a sense of its responsibilities that it passes muster half the time as a new type of asceticism.
For as the interposition of a rivulet, however small, will occasion the line of the phalanx to fluctuate, so any trifling disagreement will be the cause of seditions; but they will not so soon flow from anything else as from the disagreement between virtue and vice, and next to that between poverty and riches.
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.
