Any man who tries to be good all the time is bound to come to ruin among the great number who are not good. Hence a prince who wants to keep his authority must learn how not to be good, and use that knowledge, or refrain from using it, as necessity requires.

Every little advantage is of great moment when men have to come to blows.

And if, to be sure, sometimes you need to conceal a fact with words, do it in such a way that it does not become known, or, if it does become known, that you have a ready and quick defense.

Necessities can be many, but the one that is stronger is that which constrains you to win or to die.

No enterprise is more likely to succeed than one concealed from the enemy until it is ripe for execution.

One can generally say this about men: that they are ungrateful, fickle, simulators and deceivers, avoiders of danger, greedy for gain; and while you work for their good they are completely yours, offering you their blood, their property, their lives, and their sons when danger is far away; but when it comes nearer to you, they turn away.

With difficulty he is beaten who can estimate his own forces and those of his enemy.
