Some may wonder how it can happen that Agathocles, and his like, after infinite treacheries and cruelties, should live for long secure in his country, and defend himself from external enemies, and never be conspired against by his own citizens; seeing that many others, by means of cruelty, have never been able even in peaceful times to hold the state, still less in the doubtful times of war. I believe that this follows from severities[2] being badly or properly used. Those may be called properly used, if of evil it is possible to speak well, that are applied at one blow and are necessary to one's security, and that are not persisted in afterwards unless they can be turned to the advantage of the subjects. The badly employed are those which, notwithstanding they may be few in the commencement, multiply with time rather than decrease. Those who practise the first system are able, by aid of God or man, to mitigate in some degree their rule, as Agathocles did. It is impossible for those who follow the other to maintain themselves.
