"It is enough", this malicious man tells us, "to extinguish the line of the defeated prince." Can one read this without quivering in horror and indig… - Frederick II of Prussia

It is a fact that princes who try to raise other princes with violence, end up destroying themselves.

Hero demolished both his friends and his soldiers, who had helped him in the execution of his plans; he found new friends, and raised other troops. I say, in spite of Machiavel and of the ingrates, that this policy of Hero is very bad, and that it is much more prudent to trust the troops which have tested and known value, and have friends whose loyalty has also been tested. The new and unknown ones are also unsafe. I leave the reader to push this reasoning further; all those who detest ingratitude, and who truly value friendship, will not remain neutral on this matter.

(About Cesare Borgia) What cruelties were not the result of his? Who could count all his crimes? Such was the man that Machiavel prefers to all the great geniuses of his time, and to the heroes of antiquity, and of which he finds the life and action make a good example for those that fortune favors.
