The Prince (Prestwick House Literary Touchstone Press) by Niccolo Machiavelli
Need to seize a country? Have enemies you must destroy? In this handbook for despots and tyrants, the Renaissance statesman Machiavelli sets forth how to accomplish this and more, while avoiding the awkwardness of becoming generally hated and despised.
"Men ought either to be well treated or crushed, because they can avenge themselves of lighter injuries, of more serious ones they cannot; therefore the injury that is to be done to a man ought to be of such a kind that one does not stand in fear of revenge."
For nearly 500 years, Machiavelli's observations on Realpolitik have shocked and appalled the timid and romantic, and for many his name was equivalent to the devil's own. Yet, The Prince was the first attempt to write of the world of politics as it is, rather than sanctimoniously of how it should be, and thus The Prince remains as honest and relevant today as when Machiavelli first put quill to parchment, and warned the junior statesman to know how to do wrong, and to make use of it or not according to necessity.
