Any man who tries to be good all the time is bound to come to ruin among the great number who are not good.
Niccolo MachiavelliA wise ruler ought never to keep faith when by doing so it would be against his interests.
Niccolo MachiavelliThe 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 MachiavelliIf the chief party, whether it be the people, or the army, or the nobility, which you think most useful and of most consequence to you for the conservation of your dignity, be corrupt, you must follow their humor and indulge them, and in that case honesty and virtue are pernicious.
