This chapter highlights the crucial role of property in the history of rights, both as one of the key concepts driving the development of rights theories (and protections) onward from an early time, and their modern adaptations in the eighteenth century. Given property’s oversized importance in this history, it is surprisingly missing from many recent accounts. But since the French Revolution, property has been at the heart of most political efforts to secure and protect rights. As this chapter demonstrates, the centrality of property for so many later reforms can in large part be credited to the insistent claims of the Physiocrats. Political society, they argued, must extend natural rights, rather than replace them with positive laws. Economic circulation was itself part and parcel of a “natural order,” with subjective rights at its basis. The chapter suggests that contemporary theories and assessments of the role of rights in political society remain partial as long as they do not include an understanding of the historical role that property has played among them.
