Speak as you think, be what you are, pay your debts of all kinds. I prefer to be owned as sound and solvent, and my word as good as my bond, and to be what cannot be skipped, or dissipated, or undermined, to all the eclat in the universe. This reality is the foundation of friendship, religion, poetry, and art.
When campaigning, be swift as the wind; in leisurely march, majestic as the forest; in raiding and plundering, like fire; in standing, firm as the mountains. As unfathomable as the clouds, move like a thunderbolt.
A 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.
It is the fate of most men who mingle with the world, and attain even the prime of life, to make many real friends, and lose them in the course of nature. It is the fate of all authors or chroniclers to create imaginary friends, and lose them in the course of art. Nor is this the full extent of their misfortunes; for they are required to furnish an account of them besides.
How laudable it is for a prince to keep good faith and live with integrity, and not with astuteness, every one knows. Still the experience of our times shows those princes to have done great things who have had little regard for good faith, and have been able by astuteness to confuse men's brains, and who have ultimately overcome those who have made loyalty their foundation.
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.
These are the six ways of courting defeat - neglect to estimate the enemy's strength; want of authority; defective training; unjustifiable anger; nonobservance of discipline; failure to use picked men.
A cup is useful only when it is empty; and a mind that is filled with beliefs, with dogmas, with assertions, with quotations is really an uncreative mind.
