The Virtue of a Ruler

Virtue is what you can doto the maximum amount of ability. Events from the century, events every day, are a combination of fortuna and vertu. The king knows that this is something he cannot control. But he can do whatever it takes in order to minimize the effect,. the deliterious effects, of flooding. So that's what machiavelli wrote about, the dualistic stratagy of Fortuna and Vertu - things you can't control and things you can control.
