Epigraph: 'We daily see men do for their party, for their sect, for their country, for their favourite schemes of political and social reform, what they would not do to enrich or to avenge themselves. At a temptation directly addressed to our private cupidity or our private animosity, whatever virtue we have takes the alarm. But virtue itself may contribute to the fall of him who imagines that it is in his power, by violating some general rule of morality, to confer an important benefit on a church, on a commonwealth, on mankind. He silences the remonstrance's of conscience, and hardens his heart against the most touching spectacles of misery, by repeating to himself that his intentions are pure, that his objects are noble, that he is doing a little evil for the sake of a great good. By degrees he comes altogether to forget the turpitude of the means in the excellence of the end, and at length perpetrates without one internal twinge acts which would shock a buccaneer.'
