Niccolo Machiavelli expresses his vision of the political philosophy in his book The Prince. We can see a continuity with the ideas of Aristotle in his Book Politics. Niccolo Machiavelli studies the "principalities" that according to Aristotle are "tyrannies". Aristotle, on the other hand, fundamentally studies the oligarchies. According to Aristotle, tyrannies and oligarchies are deviations from the correct regime. In essence, Machiavelli's book is a manual for the tyrant, the dictator, although it is not a work about ethics, it deals with the rationality and common sense of who should govern and the principles or ideas that he expresses are perfectly applicable to the current political philosophy. The goal of tyrannies is according to Aristotle the defense of the tyrant, thence Machiavelli expresses this in other terms:
"So that, a prince should not have another goal or another concern, nor should he consider another mission as his own than that of war, its organization and discipline", The Prince, Cap. 14
Niccolo Machiavelli wrote his book as a gift to Lorenzo de' Medici, in this, the author tries to base the political principles that underlie tyrannies (Aristotle), or to say the "principalities". According to Machiavelli, the Prince can arise by luck, by cunning or by both, that is to say, a fortunate cunning. By cunning Machiavelli understands that particular knowledge about the people and the nobility.
For Machiavelli a principality is based on two factors: the luck of the times and the virtue of the prince.
About this he expresses:
"The only safe and lasting defenses are those that depend on yourself and your virtue", Chapter XXIV, The Prince
"Luck governs half of our actions, but still lets us rule the other half", Chapter XXV, The Prince
He also gives a series of advices to the Prince to succeed in his ventures:
"A prince has to contrive to give an image of greatness and exceptional ingenuity in all his actions", Chapter XXI
"A prince must also show appreciation for the virtue, welcoming virtuous men, and honoring those who excel in some activity", Chapter XXI
"It is better to be impetuous than prudent, because since luck is like a woman ... the woman is a friend of the Young men because they are less cautious, more fierce and govern her with more audacity", Chapter XXV
Nicolás Machiavelli resembles Aristotle in that although ethical standards are not necessary, common sense is, while he gives his principles shows how the ancient principalities succeeded or failed according to the ideas exposed. Machiavelli names Moses, Darius the Persian, Alexander the Great and Italian political figures of the fifteenth century. Although the current application is questionable, his ideas are tempered in the politics of the modern states and especially in the current European monarchies.
