Book 1.24

A proposal was once made in the Senate to distinguish slaves from free men by their dress: it was then discovered how dangerous it would be for our slaves to be able to count our numbers. Be assured that the same thing would be the case if no one's offence is pardoned: it will quickly be discovered how far the number of bad men exceeds that of the good. Many executions are as disgraceful to a sovereign as many funerals are to a physician: one who governs less strictly is better obeyed. The human mind is naturally self-willed, kicks against the goad, and sets its face against authority; it will follow more readily than it can be led. As well-bred and high-spirited horses are best managed with a loose rein, so mercy gives men's minds a spontaneous bias towards innocence, and the public think that it is worth observing. Mercy, therefore, does more good than severity.
