Abstract

A private property right is a collection of particular rights that relate to the control of an object. The ground for such moral rights rests on the value of project pursuit. It does so because the individual ownership of particular objects is intimately related to the formation and application of a coherent set of projects that are the major parts of a self-shaped life. Problems arise in explaining how unowned property is appropriated. Unilateral acts with regard to an object, e.g., mixing in one’s labor into it, probably don’t ground particular rights to private property. Nor do bilateral contracts since a stable pre-institutional contract with regard to appropriation is not likely to form. However, a conventional method of appropriation can allow for such appropriation while at the same time preserving the pre-institutional nature of such rights. This theory can also account for a person’s property rights in her own body. However, the value of project formation requires that persons have at least some private property that is to serve as the object of their projects. These positive rights to property undermine the libertarian claim that all non-commitment-based rights are negative. However, a further empirical argument is needed in order to justify protecting these positive moral rights to private property by positive legal rights.
