It is necessary that the prince should know how to color his nature well, and how to be a hypocrite and dissembler. For men are so simple, and yield so much to immediate necessity, that the deceiver will never lack dupes.
Never lead your soldiers to battle if you have not first confirmed their spirit and known them to be without fear and ordered; and never test them except when you see that they hope to win.
the wise man should always follow the roads that have been trodden by the great, and imitate those who have most excelled, so that if he cannot reach their perfection, he may at least acquire something of its savour.
A prince must not have any other object nor any other thought… but war, its institutions, and its discipline; because that is the only art befitting one who commands.
A prince is also respected when he is a true friend and a true enemy; that is, when he declares himself on the side of one prince against another without any reservation.
If 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.
A prince ought to have no other aim or thought, nor select anything else for his study, than war and its rules and discipline; for this is the sole art that belongs to him who rules, and it is of such force that it not only upholds those who are born princes, but it often enables men to rise from a private station to that rank. And, on the contrary, it is seen that when princes have thought more of ease than of arms they have lost their states. And the first cause of your losing it is to neglect this art; and what enables you to acquire a state is to be master of the art.
