A man who wishes to make a profession of goodness in everything must necessarily come to grief among so many who are not good. Therefore, it is necessary for a prince, who wishes to maintain himself, to learn how not to be good, and to use this knowledge and not use it according to the necessity of the case.
Niccolo MachiavelliA prince ought to have two fears, one from within, on account of his subjects, the other from without, on account of external powers.
Niccolo MachiavelliOne can say this in general of men: they are ungrateful, disloyal, insincere and deceitful, timid of danger and avid of profit...Love is a bond of obligation that these miserable creatures break whenever it suits them to do so; but fear holds them fast by a dread of punishment that never passes.
Niccolo MachiavelliI 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.
Niccolo MachiavelliA prince must not have any objective nor any thought, nor take up any art, other than the art of war and its ordering and discipline; because it is the only art that pertains to him who commands. And it is of such virtue that not only does it maintain those who were born princes, but many times makes men rise to that rank from private station.
