I hold it to be a proof of great prudence for men to abstain from threats and insulting words toward anyone, for neither diminishes the strength of the enemy.
That prince is highly esteemed who conveys this impression of himself, and he who is highly esteemed is not easily conspired against; for, provided it is well known that he is an excellent man and revered by his people, he can only be attacked with difficulty.
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.
And above all you ought to guard against leading an army to fight which is afraid or which is not confident of victory. For the greatest sign of an impending loss is when one does not believe one can win.
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.
Sometimes it has been of great moment while the fight is going on, to disseminate words that pronounce the enemies' captain to be dead, or to have been conquered by another part of the army. Many times this has given victory to him who used it.
....it cannot be called ingenuity to kill one's fellow citizens, to betray friends, to be without faith, without mercy, without religion; by these means one can aquire power but not glory.
