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.
Niccolo MachiavelliIn truth, there never was any remarkable lawgiver amongst any people who did not resort to divine authority, as otherwise his laws would not have been accepted by the people; for there are many good laws, the importance of which is known to be the sagacious lawgiver, but the reasons for which are not sufficiently evident to enable him to persuade others to submit to them; and therefore do wise men, for the purpose of removing this difficulty, resort to divine authority.

Niccolo MachiavelliHe who desires or attempts to reform the government of a state and wishes to have it accepted, must at least retain the semblance of the old forms; so that it may seem to the people that there has been no change in the institutions, even though in fact they are entirely different from the old ones. For the great majority of mankind are satisfied with appearances, as though they were realities.
Niccolo MachiavelliSome princes, so as to hold securely the state, have disarmed their subjects, others have kept their subject towns distracted by factions...Our forefathers, and those who were reckoned wise, were accustomed to say that it was necessary to hold Pistoia [an Italian city] by factions and Pisa by fortress, and with this idea they fostered quarrels in some of their tributary towns so as to keep possession of them the more easily.
