A prince must have no other objective, no other thought, nor take up any profession but that of war, its methods and its discipline, for that is the only art expected of a ruler. And it is of such great value that it not only keeps hereditary princes in power, but often raises men of lowly condition to that rank. It may be noted, on the other hand, that when princes have given more thought to fine living than to arms, they have lost their states. The first cause of losing them is the neglect of this art, just as the first means of gaining them is proficiency in it.
