Abstract
If a political theory of ownership is to be acceptable, it must rationally prescribe one system or model of ownership as opposed to others. Such a prescription would be rational only if strong normative arguments could be mounted to show it more desirable than its competitors. Thus, the prefatory work for such a theory would consist in the construction of viable models of ownership from which a sound choice could be made. This project would, however, be successful only if originating from coherent, evaluatively neutral analyses of the concept of ownership and other related ideas. The point of this essay is to do this prefatory work.
