What Is Property?

What Is Property?: or, An Inquiry into the Principle of Right and of Government (French: Qu'est-ce que la propriété ? ou Recherche sur le principe du Droit et du Gouvernement) is a work of nonfiction on the concept of property and its relation to anarchist philosophy by the French anarchist and mutualist Pierre-Joseph Proudhon, first published in 1840. In the book, Proudhon most famously declared that "property is theft".

Proudhon believed that the common conception of property conflated two distinct components which, once identified, demonstrated the difference between property used to further tyranny and property used to protect liberty. He argued that the result of an individual's labor which is currently occupied or used is a legitimate form of property. Thus, he opposed unused land being regarded as property, believing that land can only be rightfully possessed by use or occupation (which he called "possession"). As an extension of his belief that legitimate property (possession) was the result of labor and occupation, he argued against such institutions as interest on loans and rent.

The proprietor, the robber, the hero, the sovereign—for all these titles are synonymous—imposes his will as law, and suffers neither contradiction nor control; that is, he pretends to be the legislative and the executive power at once ... [and so] property engenders despotism ... That is so clearly the essence of property that, to be convinced of it, one need but remember what it is, and observe what happens around him. Property is the right to use and abuse ... if goods are property, why should not the proprietors be kings, and despotic kings—kings in proportion to their facultes bonitaires? And if each proprietor is sovereign lord within the sphere of his property, absolute king throughout his own domain, how could a government of proprietors be any thing but chaos and confusion?

Proudhon contrasted the supposed right of property with the rights (which he considered valid) of liberty, equality, and security, saying: "The liberty and security of the rich do not suffer from the liberty and security of the poor; far from that, they mutually strengthen and sustain each other. The rich man’s right of property, on the contrary, has to be continually defended against the poor man’s desire for property." He further argued that the right of property contradicted these other rights: "Then if we are associated for the sake of liberty, equality, and security, we are not associated for the sake of property; then if property is a natural right, this natural right is not social, but anti-social. Property and society are utterly irreconcilable institutions."
