Principles of Politics Applicable to All Governments

Constant's central argument is that political authority is necessarily limited—no government or society has the right to exercise absolute sovereignty of any sort. He rejects Rousseau's claim that the social contract requires individuals to surrender all their rights to the community. Constant contends that society cannot itself exercise power; it must always delegate authority to a government. Any delegation of unlimited power therefore betrays the governed, who have surrendered their rights not to 'no one' but to a specific body of rulers. This critique of unlimited sovereignty—whether monarchical or popular—is the book's most distinctive contribution to liberal political theory.

Constant devotes the opening books to dismantling Rousseau's theory. He argues that Rousseau's 'eloquent and absurd' claim—that individuals surrender all rights to the community and thereby remain free because they obey no one but themselves—rests on a category error. The 'community' or 'general will' cannot act; it must always act through a delegate. Therefore, when individuals surrender their rights to the sovereign, they in fact surrender them to the government that exercises sovereign power. Constant concludes that Rousseau's theory, despite its democratic pretensions, furnishes 'deadly pretexts' for tyranny by legitimizing unlimited authority.

Constant uses 'arbitrary measures' to describe governmental actions that target individuals or groups outside the protection of regular law—emergency powers, preventive detention, exceptional tribunals, and the prerogative of preventing crimes. Book V of the Principles is devoted to this subject because Constant witnessed the French Revolution's descent into terror, where 'public safety' justified pursuing 'individual existence into its most intimate retreats.' He argues that arbitrary government is a moral blight that corrupts political life and undermines the habits of peaceful, law-abiding society. It is also self-defeating: it creates the insecurity it claims to combat.

The 1806 Principles contains Constant's earliest sustained elaboration of the distinction between ancient and modern liberty. Book XVI ('On Political Authority in the Ancient World') and Book XVII ('On the True Principles of Freedom') develop the argument that the liberty of the ancients consisted in collective participation in sovereign power, while modern liberty consists in the peaceful enjoyment of individual independence. Constant argues that the ancient model, if imposed on modern commercial societies, would require sacrifices no modern people will accept. His 1819 lecture, delivered thirteen years later, condensed this argument into its famous form.

Constant composed the Principles in 1806 but chose not to publish it, likely due to changes in the political climate under Napoleon. It remained unpublished in its full form until Etienne Hofmann's critical edition appeared in 1980. In 1815 Constant published a revised, shortened version titled Principes de politique applicables à tous les gouvernements représentatifs et particulièrement à la Constitution actuelle de la France. The 1806 text is the fuller, more comprehensive work; the 1815 version adapts the argument to the specific context of the restored French monarchy. The 2003 Liberty Fund English translation is based on the 1806 manuscript.

Critics have raised several objections. First, Constant's appeal to limits on sovereignty is clearer about what he rejects—absolute power—than about what grounds those limits. He invokes religion and a 'spiritual realm' above the human will, but his ultimate source of limits remains ill-defined. Second, his liberal theory assumes a commercial society of property-owning individuals, and his account of who qualifies for political rights is restrictive by modern standards. Third, some argue that his emphasis on negative liberty risks encouraging political apathy, leaving citizens vulnerable to new forms of despotism. Constant himself acknowledged this tension in his later work.
