The Romans never allowed a trouble spot to remain simply to avoid going to war over it, because they knew that wars don't just go away, they are only postponed to someone else's advantage. Therefore, they made war with Philip and Antiochus in Greece, in order not to have to fight them in Italy... They never went by that saying which you constantly hear from the wiseacres of our day, that time heals all things. They trusted rather their own character and prudence- knowing perfectly well that time contains the seeds of all things, good as well as bad.
Niccolo MachiavelliA battle that you win cancels any other bad action of yours. In the same way, by losing one, all the good things worked by you before become vain.
Niccolo MachiavelliA prince... must learn from the fox and the lion... One must be a fox in order to recognize traps, and a lion to frighten off wolves. Those who act simply as lions are stupid. So it follows that a prudent ruler cannot, and must not, honour his word when it places him at a disadvantage and when the reasons for which he made his promise no longer exist.
Niccolo MachiavelliSince the handling of arms is a beautiful spectacle, it is delightful to young men.
Niccolo Machiavelli....for friendships that are acquired by a price and not by greatness and nobility of character are purchased but are not owned, and at the proper moment they cannot be spent.
