We begin with the most famous slogan of the anti-property movement: Pierre-Joseph Proudhon's "property is theft." Bastiat had no difficulty dismantling this formula, for it is self-contradictory on its face: if property is theft, then theft is property, what is legitimate is illegitimate, and what is illegitimate is legitimate. The phrase sounds revolutionary, but it says nothing coherent. Bastiat, in his Œuvres complètes, returned systematically to the origin of property, work, self-ownership, human faculties, and demonstrated that it is grounded in the facts of every society and every age.

The systems of unfreedom postulate an original spoliation: all the best lands, they claim, were seized by force at the dawn of history, and the present owners merely enjoy without labor what their ancestors stole. But this narrative contains two fatal errors.

First, it assumes an ease of enrichment that contradicts all experience. The Marxist vision, and it is strikingly present in all socialist thought, imagines that profits fall automatically from capital, as if one merely had to invest and then collect. There are no bankruptcies in this picture, no sleepless nights of worry, no enterprises that fail because they do not reproduce in value what they cost. This is fantasy, not fact.

Second, if the original despoilment were real, we would expect to see the descendants of these ancient plunderers among the wealthiest families today. But where are they? As time advances, exchanges are conducted legitimately, value for value, work for work. Properties that exist today have been validated a thousand times over by labor and voluntary exchange. Moreover, the conditions of production are constantly evolving: lands once considered supremely valuable can lose their worth entirely, while previously neglected territories, as the contemporary scramble for rare-earth minerals illustrates, can become immensely precious. The idea that all wealth was fixed and seized at the beginning is not merely a moral error; it is contrary to the facts of economic history.

Uniform laws and administrative centralization are in direct contradiction with the natural diversity of human beings. These systems impose uniform ways of working, enjoying property, and organizing life, yet property, by its nature, should confer the liberty to use it as one sees fit, within the limits of others' rights. Under regimes of unfreedom, the nominal owner becomes a mere usufructuary: the true proprietor is the state. We are brought back, unwittingly, to the principles of the Ancien Régime, when the king was the ultimate owner of all lands. The systems of unfreedom are, at bottom, always retrograde, they return to the past they claim to have surpassed.

The weakening of self-interest is another fundamental contradiction. Every human being is born with a distinct personality that deepens throughout life. Freedom allows self-interest to find its own satisfactions, voluntarily and peacefully, at its own pace. Unfreedom imposes standardized satisfactions that correspond to no one's actual needs.

The rejection of parental love in education is particularly severe. State education replaces the natural feelings of the mother and father, their intimate knowledge of their child's personality, their emotional investment, with the cold administrative guardianship of a political apparatus that changes with every election cycle. The state has no sentiment, no appreciation for the unique personality of each child. To substitute it for the natural tutors is not progress; it is a contradiction of the most fundamental facts of human attachment.

Attempts to control thought take many forms: subsidized press, monopolistic national education, limitations on religious freedom, regulated democracy. All are attacks on the very nature of human thought, which is formed within, belongs intimately to each individual, and is the purest expression of self-ownership. Systems of coercion attempt to break the natural link between a person's ideas and their peaceful expression, thereby depriving society of the creative confrontation of opinions from which truth emerges.

This reveals a profound misunderstanding. Thought cannot be controlled from outside without destroying the capacity to think creatively and critically. Systems that impose intellectual orthodoxy end up stifling the very innovation and progress on which the advancement of civilization depends.

Competition is a fundamental datum of human existence, made inescapable by the finiteness of resources. Systems of unfreedom wage an impossible war against it, not realizing that competition cannot be suppressed, only redirected. Throughout history, it has existed in two principal forms: violent competition (where groups seize resources by force) and peaceful competition (where individuals exchange freely). Political competition, the acquisition of resources through majority vote, is, in essence, a continuation of violent competition under a democratic disguise: one group acquires what another has produced, not through exchange but through legal compulsion.

The aspiration to abolish the law of supply and demand is equally futile. Paul Leroy-Beaulieu (1843–1916), one of the rare liberals elected to the National Assembly, recounted attending socialist public meetings where he was accused of having "voted for" the law of supply and demand, as though it were a legislative act! But the law of supply and demand is simply the natural expression of free human action: when a price rises, individuals reduce their consumption; when it falls, they increase it. This behavior is universal, arising from the structure of human sensation and choice. No decree can abolish it.

The dream of abolishing private property encounters a similar contradiction. Leroy-Beaulieu, in his Le Collectivisme, explained it vividly to the workers and peasants who were seduced by the ideal of collectivization: the enjoyment of commonly owned property is profoundly impoverished compared to private ownership. Each citizen is theoretically the owner of one sixty-five-millionth of a national forest or public monument, but when he visits it (if he has the right to visit it), he barely feels like a proprietor at all. Collectivization destroys what the liberals called "the master's eye", that special attention, that personal incentive to improve and maintain, that only the true owner possesses. The inevitable result is neglect and the sub-optimal use of resources.

Finally, the abolition of interest on money and the regulation of profits are attacks on voluntary exchange mechanisms. Interest is simply the price at which capital is transmitted from one who has it to one who needs it, reflecting the time, risk, and sacrifice of the lender. To suppress it, as the medieval prohibitions on usury attempted, does not eliminate the need for capital transmission; it merely forces it underground, creating workarounds and injustices, as the role imposed upon Jewish moneylenders in the Middle Ages tragically illustrates.

These contradictions could be multiplied endlessly. But the pattern is clear: every system of unfreedom wages war against facts, facts of human nature, facts of the physical world, facts of economic life. The systems of liberty, by contrast, are built upon these facts. With this contrast established, we now turn to the history of freedom, to trace, across the centuries, how liberty has gradually won its way against the forces of constraint.
