The Art of War-Niccolo Machiavelli-1521

But because military institutions have become completely corrupt and far removed from the ancient ways, these sinister opinions have arisen which make the military hated and intercourse with those who train them avoided. And I, judging, by what I have seen and read, that it is not impossible to restore its ancient ways and return some form of past virtue to it, have decided not to let this leisure time of mine pass without doing something, to write what I know of the art of war, to the satisfaction of those who are lovers of the ancient deeds.
