Necessity and Reason of State

How Discourses on Livy develops Necessity and Reason of State.

The book argues that when the safety of the country is at stake, no consideration of justice, mercy, or shame should intervene, and that rulers must sometimes employ harsh measures, including destroying rebellious cities, to secure lasting peace.

Where it surfaces

  • I

    Cities are founded out of necessity (e.g., defense against enemies) or choice, and laws must enforce discipline to counteract the corrupting influence of ease.

  • III

    The necessity of laws and institutions to compel good behavior when men are free to act on their evil inclinations.

  • Chapter VI: Whether it was possible in Rome to contrive such a government as would have composed the differences between the commons and the senate

    Machiavelli emphasizes that human affairs cannot remain static and that necessity often forces a republic to expand, making the Roman model of accepting internal discord the more honorable and practical path.

  • VII

  • Chapter IX

    Machiavelli argues that extraordinary and violent actions are justified when necessary to found or reform a state for the common good.

  • Of the religion of the Romans

  • XII

  • XIII

    Religion is employed as a necessary tool to overcome political impasses and maintain civic unity, even through deception.

  • XVIII

    Discusses the need for extraordinary, even violent, measures to restore order in a corrupt state, and the rarity of virtuous rulers employing such means.

  • XXII

    The folly of risking the entire state on a small part of its forces and the unreliability of covenants under duress.

  • That we should never hazard our whole fortunes where we put not forth our entire strength; for which reason to guard a defile is often hurtful.
