The twentieth century saw a vigorous debate over the nature of rights. Will theorists argued that the function of rights is to allocate domains of freedom. Interest theorists portrayed rights as defenders of well-being. Each side declared its conceptual analysis to be closer to an ordinary understanding of what rights there are, and to an ordinary understand- ing of what rights do for rightholders. Neither side could win a decisive victory, and the debate ended in a standoff.

Critics of Robert Nozick's libertarian political theory often allege that the theory in general and its account of property rights in particular lack sufficient foundations. A key difficulty is thought to lie in his account of how portions of the world which no one yet owns can justly come to be initially acquired. But the difficulty is illusory, because the concept of justice does not meaningfully apply to initial acquisition in the first place. Moreover, the principle of self-ownership provides a (...) solid foundation for Nozick's libertarianism, and when seen in the light of that principle and its full implications, the standard purported examples of injustices in acquisition are revealed to be nothing of the kind.

I thank the directors of the Center, Fred D. Miller, Jr., Ellen Frankel Paul, and Jeffrey Paul, for hosting me. I also thank colloquium audience members at Bowling Green State University for comments on that draft. (shrink)

Suppose libertarians could prove that durable, unqualified private property rights could be created through 'original acquisition' of unowned resources in a state of nature. Such a proof would cast serious doubt on the legitimacy of the modern state. It could also render the approach to property rights that I favour irrelevant. I argue here that none of the familiar Lockean-libertarian arguments for a strong natural right to acquisition succeed, and that any successful argument for grounding a right to acquire would (...) have to use my favoured approach to property rights - the 'vector-sum' approach. I conclude with some doubts about original acquisition theory and natural property rights. (shrink)

My aim in this essay is to explore the nature and force of “original-acquisition” justifications of private property. By “original-acquisition” justifications, I mean those arguments which purport to establish or importantly contribute to the moral defense of private property by: offering a moral/historical account of how legitimate private property rights for persons first arose ; offering a hypothetical or conjectural account of how justified private property could arise from a propertyless condition; or simply defending an account of how an individual (...) can make private property in some previously unowned thing . The “original acquisition” to which such justifications centrally refer, then, may be either the first instance of legitimate private property in human history , or only the first legitimate acquisition of some particular thing . But in either case, the justification will involve or entail the defense of one or more moral principles specifying how unowned things can become privately owned — that is, the defense of the kind of principles Robert Nozick has called “principles of justice in acquisition.”.

I do not answer my title’s question in this paper. Instead, my aims are first to show that the question is worth asking, secondly to show that its answer will not be trivial, and thirdly to show that it is unclear what the answer is. From these three conclusions it follows that many contemporary Hohfeldian approaches to the conceptual analysis of rights (including those of Sumner, Jones, Kramer, Wenar and myself)1, while potentially capable of extensional accuracy, overlook an essential but (...) unidentified feature of rights: the feature which explains why duties are not rights. The paper challenges theorists to investigate what this feature is. (shrink)
