You must know, then, that there are two methods of fighting, the one by law, the other by force: the first method is that of men, the second of beasts; but as the first method is often insufficient, one must have recourse to the second.
There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first kind is excellent, the second good, and the third kind useless.
And here one must not that hatred is acquired just as much by means of good actions as by bad ones; and so, as I said above, if a prince wishes to maintain the state, he is often obliged not to be good; because whenever that group which you believe you need to support you is corrupted, whether it be the common people, the soldiers, or the nobles, it is to your advantage to follow their inclinations in order to satisfy them; and then good actions are your enemy.
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.

Well used are those cruelties (if it is permitted to speak well of evil) that are carried out in a single stroke, done out of necessity to protect oneself, and are not continued but are instead converted into the greatest possible benefits for the subjects. Badly used are those cruelties which. although being few at the outset, grow with the passing time instead of disappearing. Those who follow the first method can remedy their condition with God and with men; the others cannot possibly survive.
