A prince must be prudent enough to know how to escape the bad reputation of those vices that would lose the state for him, and must protect himself from those that will not lose it for him, if this is possible; but if he cannot, he need not concern himself unduly if he ignores these less serious vices.
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.
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.
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.
