The most effective way of attacking vice is to expose it to public ridicule. People can put up with rebukes but they cannot bear being laughed at: they are prepared to be wicked but they dislike appearing ridiculous.
The defects of human nature afford us opportunities of exercising our philosophy, the best employment of our virtues. If all men were righteous, all hearts true and frank and loyal, what use would our virtues be?
If everyone were clothed with integrity, if every heart were just, frank, kindly, the other virtues would be well-nigh useless, since their chief purpose is to make us bear with patience the injustice of our fellows.
