I assert once again as a truth to which history as a whole bears witness that men may second their fortune… — Niccolò Machiavelli

Titus Livius... observes, “Most wholesome is it that in affairs of great moment, supreme authority be vested in one man.” Very different, however, is the course followed by the republics and princes of our own days, who, thinking to be better served, are used to appoint several captains or commissioners to fill one command; a practice giving rise to so much confusion, that were we seeking for the causes of the overthrow of the French and Italian armies in recent times, we should find this to be the most active of any.

Rightly, therefore, may we conclude that in sending forth an army upon service, it is wiser to entrust it to one man of ordinary prudence, than to two of great parts but with a divided command.

Cunning and deceit will every time serve a man better than force to rise from a base condition to great fortune.

It was the verdict of ancient writers that men afflict themselves in evil and weary themselves in the good, and that the same effects result from both of these passions. For whenever men are not obliged to fight from necessity, they fight from ambition; which is so powerful in human breasts, that it never leaves them no matter to what rank they rise. The reason is that nature has so created men that they are able to desire everything but are not able to attain everything: so that the desire being always greater than the acquisition, there results discontent with the possession and little satisfaction to themselves from it. From this arises the changes in their fortunes; for as men desire, some to have more, some in fear of losing their acquisition, there ensues enmity and war, from which results the ruin of that province and the elevation of another.
