““It is necessary’, he writes, for a prince to learn ‘how not to be good’ (Ch. XV). Machiavelli’s wording on this matter is extremely precise: a man who wants ‘to profess goodness at all times’ will inevitably fail because he is surrounded by many unscrupulous men. Hence, ‘it is necessary for a prince who wishes to maintain himself to learn how not to be good, and to use this knowledge or not to use it according to necessity’ (Ch. XV).””
