State of nature theories have a long history and play a lively role in contemporary work. Theories of this kind share certain nontrivial commitments. Among these are commitments to inclusion of a Lockean proviso among the principles of justice and to an assumption of invariance of political principles across changes of circumstances. In this article I want to look at those two commitments and bring to light what I believe are some important difficulties they engender. For nonpattern state of (...) nature theories, the justness of a society is marked by the conformance of the society to procedural principles. Distributions of resources and the like have no particular import for questions of justice. Whatever may later result, so long as it came about in accordance with the rules determined by the principles of justice, is itself just. The Lockean proviso is one of the principles of justice governing property and other rights of nonpattern theories of justice. The proviso hangs as a "shadow" over the results of the operation of the other (usual) principles of justice. It is intended to remedy a complaint which arises when the positions of those no longer at liberty to use some resource are worsened (1) by no longer being able to use freely what they previously were free to use and (2) in such a way that they fall below a "baseline." Following Locke, a traditional formulation of the proviso is to allow acquisition just so long as there is "enough and as good" left over for others. Section I concerns the relation of the Lockean proviso to pattern and nonpattern principles of justice, demonstrating that a Lockean proviso turns a nonpattern into a pattern theory of justice. Section II is about the relation of the Lockean proviso to the ideas revealed by an examination of a state of nature, suggesting reasons to reject ideal theories of justice. (shrink)

Within Robert Nozick's theory of Justice as presented in his Anarchy, State and Utopia, does the Lockean proviso dovetail with the theory of entitlement? The main burden of this paper is to establish that far from dovetailing, there is a serious conflict between the two.Nozick's theory of Justice consists of at least three principles, namely, the principle of Justice in acquisition, the principle of Justice in transfer, and the principle of rectification of injustice. These principles treat the topics of (...) how unheld things came to be held, how they came to be transferred, and how injustice in respect to them came to be corrected or rectified. Although Nozick does not provide a detailed philosophical picture of these principles of Justice, he says enough about each of them by way of examples and explanations to constitute a powerful, criticizable doctrine.

: In a recent essay, “Forcing Nozick Beyond the Minimal State: The Lockean Proviso and Compensatory Welfare,” I argue that Nozick’s own reading of the Lockean Proviso commits him to a welfare state. In a forceful response, Jan Narveson calls my argument into question by arguing for an especially austere reading of the Lockean Proviso as ….

Interpreters of Robert Nozick’s political philosophy fall into two broad groups concerning his application of the ‘Lockean proviso’. Some read his argument in an undemanding way: individual instances of ownership which make people worse off than they would have been in a world without any ownership are unjust. Others read the argument in a demanding way: individual instances of ownership which make people worse off than they would have been in a world without that particular ownership are unjust. While (...) I argue that the former reading is correct as an interpretive matter, I suggest that this reading is nonetheless highly demanding. In particular, I argue that it is demanding when it is expanded to include the protection of nonhuman animals; if such beings are right bearers, as more and more academics are beginning to suggest, then there is no nonarbitrary reason to exclude them from the protection of the proviso.

In this essay I propose to explicate and defend a new and improved version of a Lockean proviso—the self-ownership proviso . I shall presume here that individuals possess robust rights of self-ownership. I shall take it that each individual has strong moral claims over the elements which constitute her person, e.g., her body parts, her talents, and her energies. However, in the course of the essay, I shall be challenging what I take to be the standard conception of self-ownership (...) and proposing an enrichment of that conception. The SOP is presented and in part justified as an implication of the right of self-ownership as it is more richly conceived—hence its designation as the self-ownership proviso. As an implication of the right of self-ownership which is also compatible, in theory and practice, with extensive and robust private property rights, the SOP is offered as an integral element of classical-liberal political theory. (shrink)

Locke's defense of private property rights includes what is called a proviso— "the Lockean proviso"—and some have argued that in terms of it the right to private property can have various exceptions and it may not even be unjust to redistribute wealth that is privately owned. I argue that this cannot be right because it would imply that one's right to life could also have various exceptions, so anyone's life (and labor) could be subject to conscription if some would (...) need it badly enough. Since this could amount to enslavement and involuntary servitude, it would be morally and legally unacceptable. Key Words: rights • John Locke • Lockean proviso • scarcity. (shrink)

Ecological refugees are expected to make up an increasing percentage of overall refugees in the coming decades as predicted climate change related disasters will displace millions of people. In this essay, I focus on those rights ecological refugees may claim on the basis of collective self-determination. To this end, I will focus on a few specific cases that I call cases of ‘ecological refugee states’. Tuvalu, the Maldives, and to a certain extent, Bangladesh are predicted to be ecological refugee states (...) in the near future. These are states whose entire (or close to it) geographical territory is predicted to be lost to rising sea levels; the collective body of the people will itself become an ecological refugee.The question is: what may the people of an ecological refugee state legitimately claim on the basis of their right to self-determination? Should we redraw state borders to accommodate a New Tuvalu? I argue that a plausible position regarding territorial rights is that when (1) a people clearly is (or recently was) self-determining and has a legitimate claim to continue to be self-determining, and (2) the self-determination of a people is existentially threatened because the people lacks territorial rights, that (3) the people becomes a candidate for sovereign over a new territory. The result is that existing state borders may need to change to accommodate something like a New Tuvalu. To generate these results on behalf of ecological refugee states, I examine the principles of the system of territorial states. Because the system of territorial states is a system of exclusive rights over goods, especially land, it is possible that it is subject to the conditions of a Lockean proviso mechanism. This paper is dedicated mainly to adapting a version of the Lockean proviso for use in territorial rights theory. (shrink)

Does intellectual property satisfy the requirements of the Lockean proviso, that the appropriator leave “enough and as good” or that he at least not “deprive others”? If an author's appropriation of a work he has just created is analogous to a drinker “taking a good draught” in the flow of an inexhaustible river, or to someone magically “causing springs of water to flow in the desert,” how could it not satisfy the Lockean proviso?

This paper explores the implications of libertarianism for welfare policy. There are two central arguments. First, the paper argues that if one adopts a libertarian framework, it makes most sense to be a Lockean right-libertarian. Second, the paper argues that this form of libertarianism leads to the endorsement of a fairly extensive set of redistributive welfare programs. Specifically, the paper argues that Lockean right-libertarians are committed to endorsing welfare programs under which the receipt of benefits is conditional on (...) meeting a work requirement, and also endorsing some form of publicly funded jobs of last resort for potential welfare recipients.

It is common to posit a clear opposition between the values served by property systems and the value of the environment. To give the environment its due, this view holds, the role of private property needs to be limited. Support for this has been said to be found in Locke’s famous ‘enough and as good’ proviso. This article shows that this opposition is mistaken, and corrects the implied reading of Locke’s proviso. In reality, there is no opposition between property and (...) the environment. This is shown using Locke’s theory of appropriation, as well as the real-life case of instream water appropriation. (shrink)

Libertarians have long been divided over how best to interpret the Lockean proviso, which requires that one leave “enough and as good” in common for others after one’s appropriation. This article sheds light on this exegetical question in relation to its qualitative part through a contextual analysis of Locke’s often neglected writings on ….

: Critics of Nozick have claimed that his formulation of the Lockean proviso is too permissive to serve as a morally plausible constraint on resource acquisition. In this essay, I advance a new critique of Nozick’s entitlement theory. In particular, I argue that even on his own permissive formulation of the Lockean proviso, he faces ….

A private property account is central to a liberal theory of justice. Much of the appeal of the Lockean theory stems from its account of the so-called `enough-and-as-good' proviso, a principle which aims to specify each employable person's fair share of the earth's material resources. I argue that to date Lockeans have failed to show how the proviso can be applied without thereby undermining a guiding intuition in Lockean theory. This guiding intuition is that by interacting in accordance (...) with the proviso persons interact as free and equal, or as reciprocally subject to the `laws of nature' rather than as subject to one another's arbitrary will. Because Locke's own and contemporary Lockean conceptions of the proviso subject some persons to some other persons' arbitrary will, the proviso so conceived cannot function as it should, namely as a principle that restricts interacting persons' actions reciprocally and thereby enables Lockean freedom under law. (shrink)

I argue in this paper that Locke and contemporary Lockeans underestimate the problems involved in their frequent, implicit assumption that when we apply the proviso we use the latest scientific knowledge of natural resources, technology, and the economy’s operations. Problematic for these theories is that much of the pertinent knowledge used is obtained through particular persons’ labor. If the knowledge obtained through individuals’ labor must be made available to everyone and if particular persons’ new knowledge affects the proviso’s proper application, (...) then some end up without freedom to pursue their own ends and some find their freedom subject to others’ arbitrary will. (shrink)

A libertarian theory of justice holds that persons are self-owners and have the Hohfeldian moral power to justly acquire property rights in initially unowned external resources. Different variants of libertarianism can be distinguished according to their stance on the famous Lockean proviso. The proviso requires, in Locke’s words, to leave ‘enough and as good’ for others, and thus specifies limits on the acquisition of property. Left-libertarians accept an egalitarian interpretation of the proviso, ‘right-libertarians’ either reject any kind of proviso (...) or accept rather weak versions of it. In be-tween there is room for moderate interpretations of the proviso, and in particular for a sufficientarian interpretation: a ‘sufficiency proviso.’ The resulting theory of justice can be called ‘moderate libertarianism.’ In this article I make a case for moderate libertarianism, so understood. I argue that moderate libertarianism has advantages over both left- and right-libertarianism because it better coheres with the most plausible rationale for endorsing a libertarian theory of justice in the first place. (shrink)

Left and right libertarians alike are attracted to the thesis of self-ownership because, as Eric Mack says, they ‘believe that it best captures our common perception of the moral inviolability of persons’. Further, most libertarians, left and right, accept that some version of the Lockean Proviso restricts agents’ ability to acquire worldly resources. The inviolability of SO purports to make libertarianism more appealing than its egalitarian counterparts, since traditional egalitarian theories cannot straightforwardly explain why, e.g. forced organ donation and (...) forced labor are serious wrongs even when they generate more equitable outcomes or benefit the greater good. I argue that, when SO is coupled with LP, this appeal is unfounded. SO, as usually construed, allows for the possibility of justified incursions of non-culpable agents up to and including forced organ donation. I conclude by considering a few possible responses on behalf of the libertarian, assessing each one’s plausibility. (shrink)

This paper argues that the Lockean proviso can be utilized as a relevant principle of justice for food security under global climate change. Since reducing GHG emissions is key to enhancing food security, we suggest a global food security scheme that systematically allots, among all people, access to GHG sinks in food systems impacted by global climate change. For consideration of the scheme, it is important to have a principle of justice. Furthermore, it should incorporate the value of fairness. (...) A relevant principle of climate justice for food security should meet the following criteria: (1) the parties concerned under the scheme are states; (2) fairness does not undermine the requirement that the basic needs of all people must be met; (3) when determining fair burdens, a fair distribution of the rights to use GHG sinks should be sensitive both to each state’s responsibility for its GHG emissions and to (4) each state’s effort to reduce such emissions. With them in mind, first, we argue that the Lockean proviso can provide legitimate guidance for each state. Second, the Lockean proviso reasonably enjoins that a state has a right to a food system that secures its citizens’ basic needs, and a duty to meet the basic needs of other people. Third, the Lockean proviso can be deployed as a principle of both global justice and intergenerational justice for food security. Finally, the Lockean proviso enables us to count the reduction of GHG emissions by each state as “the fruits of its labors”. (shrink)

Rising sea levels may sink entire countries. Individualistic solutions to this climate catastrophe, such as those proposed by Meisels and Risse, are inadequate on both Kantian and Lockean criteria. This article concurs with Cara Nine's recent argument that such ‘ecological refugee states’ are entitled to territorial remedies. But Nine's proposal, founded on Locke's ‘sufficiency’ proviso and Nozick's famous application of it to waterholes in the desert, is instructively incorrect. Careful consideration of the distinction between land and territory, and of (...) the structure of Proviso arguments, supports a new theory of how territorial claims can be positive-sum — how the amount of territory can increase even as the land base remains constant or decreases. This normative conception of territory as the ratio of justice to land use provides a better foundation for a political solution to the problem of ecological refugee states and also generates deeper insight into the nature of territory itself. The article thus contributes not only to our thinking about redress for ecological refugees, but also to the burgeoning literatures on territory and on the Lockean Provisos. (shrink)

Matt Zwolinski argues that libertarians “should see the Basic Income Guarantee (BIG)—a guarantee that all members will receive income regardless of why they need it—as an essential part of an ideally just libertarian system.” He regards the satisfaction of a Lockean proviso—a stipulation that individuals may not be rendered relevantly worse off by the uses and appropriations of private property—as a necessary condition for a private property system’s being just. BIG is to be justified precisely because it prevents proviso (...) violations. We deem Zwolinski’s argument a “Direct Proviso-Based Argument” for BIG. We argue that because this sort of argument for the BIG is in tension with other principles libertarians within the Lockean tradition hold dear, specifically prohibitions on seizing legitimately held property and forcing individuals to labor, the Direct Proviso-Based Argument fails. (shrink)

I argue that the Lockean 'enough and as good' proviso provides support for egalitarian as opposed to libertarian or sufficientarian claims over worldly resources. These egalitarian claims apply to contemporary advanced industrial societies with money-based economies as well as primitive agrarian barter economies. But the full 'luck egalitarian' complement of equality of opportunity for welfare cannot be derived from a Lockean approach that focuses on our egalitarian claims to unowned bits of the world. For that, we need to (...) reach beyond Locke, and appeal to complaints of unfairness that have nothing in particular to do with our claims to worldly resources. (shrink)

Although John Locke’s theory of appropriation is undoubtedly influential, no one seems to agree about exactly what he was trying to say. It is unlikely that someone will write the interpretation that effectively ends the controversy. Instead of trying to find the one definitive interpretation of Locke’s property theory, this article attempts to identify the range of reasonable interpretations and extensions of Lockean property theory that exist in the contemporary literature with an emphasis on his argument for unilateral appropriation. (...) It goes through Locke’s argument point-by-point discussing the controversy over what he said and over what he perhaps should have said to make the most valuable and coherent argument. The result is an outline of Lockean theories of property: a menu of options by which one might use appropriation to justify property rights. Supporters only need to pick the version they find most plausible, but opponents should be aware of the entire menu. Anyone claiming to refute appropriation-based property rights must address not only one but all potentially valid versions of it. (shrink)

Part I of this essay supports the anti-egalitarian conclusion that individuals may readily become entitled to substantially unequal extra-personal holdings by criticizing end-state and pattern theories of distributive justice and defending the historical entitlement doctrine of justice in holdings. Part II of this essay focuses on a second route to the anti-egalitarian conclusion. This route combines the self-ownership thesis with a contention that is especially advanced by G.A. Cohen. This is the contention that the anti-egalitarian conclusion can be inferred from (...) the self-ownership thesis without the aid of additional controversial premises. Cohen advances this contention, not because he wants to support the anti-egalitarian conclusion, but rather because he wants to emphasize the need for one to reject the self-ownership thesis if one is to reject the anti-egalitarian conclusion. In Part II of this essay, I support this second route to the anti-egalitarian conclusion by reinforcing Cohen's special contention while rejecting his challenges to the self-ownership thesis. Cohen's special contention is reinforced by way of an explanation of why the redistributive state must trench upon some people's self-ownership rights. One important challenge to the self-ownership thesis is answered through the articulation of a new and improved Lockean proviso. Another challenge offered by Cohen is answered by arguing that the philosophical costs of denying the self-ownership thesis are as great as the self-ownership libertarian maintains. Thus, I defend both of the key elements of self-ownership libertarianism, the self-ownership thesis and the anti-egalitarian conclusion. (shrink)

John Locke is generally seen as an unequivocal defender of private property. However, taken normatively, certain aspects of his argument leave room for interesting loopholes with relevance to some of today’s social and political crises. This paper focuses largely on the spoilage proviso—in which Locke warns against appropriating more than one can make use of—and its possible application to abandoned buildings and the potential for legitimate productive use to be made of them by people other than the legal owner. Using (...) two case studies in which squatters have actively reversed the dereliction of abandoned buildings, this article aims to build a defence of certain types of squatting based on the limitations Locke has placed on the appropriation and the retention of property.

Sufficientarian libertarianism is a theory of justice that combines libertarianism’s focus on property rights and non-interference with sufficientarianism’s concern for the poor and needy. Persons are conceived as having stringent rights to direct their lives as they see fit, provided that everyone has enough to live a self-guided life. Yet there are different ways to combine libertarianism and sufficientarianism and hence different types of sufficientarian libertarianism. In the article I present and discuss three types, and I argue that the last (...) one overcomes the problems of the other two. The first type combines libertarianism with a sufficiency principle in what is sometimes called the ‘ethics of distribution’. The second incorporates modest welfare rights into a libertarian theory of justice. The third endorses a sufficientarian Lockean proviso for practices of private property within a libertarian theory of justice. I argue that it is superior to the others. (shrink)

Gauthier's version of the Lockean proviso (in Morals by Agreement) is inappropriate as the foundation for moral rights he takes it to be. This is so for a number of reasons. It lacks any proportionality test thus allowing arbitrarily severe harms to others to prevent trivial harms to oneself. It allows one to inflict any harm on another provided that if one did not do so, someone else would. And, by interpreting the notion of bettering or worsening one's position (...) in terms of subjective expected utility, it allows immoral manipulation of others and imposes unwarranted restrictions based on preferences that should carry no moral weight.

Defenders of strong Intellectual Property rights or of a nonutilitarian basis for those rights often turn to Locke for support.1 Perhaps because of a general belief that Locke is an advocate of all things proprietary, this move seldom receives careful scrutiny. That is unfortunate for two reasons. First, as I will argue, Locke does not issue a blank check in support of all property regimes, and the application of his reasoning to intellectual property would actually tend to favor a substantially (...) limited rights regime. Second, the attempt to understand intellectual property as an instance of Lockean property, though admittedly anachronistic, offers an opportunity to further our understanding of Locke's own thought. My major claim will be twofold: on the one hand, intellectual property would be an almost paradigmatic case of Lockean property; on the other hand, Locke's provisos—specifically the widely neglected spoilage proviso—would sharply limit the scope of any entitlements. My secondary claim will accordingly be that the spoilage proviso's neglect is undeserved, and that it deserves a more central place in our understanding of Locke. I will not here address whether Locke provides the right way to think about property, whether IP is a good idea, or whether property rights ought to include a right to destroy; my concern is to elucidate Locke's arguments and then to block this application of them.

According to the negative principle of appropriation a person can acquire an unowned resource if doing so respects a certain condition (the Lockean proviso). Contrary to some views, a proviso of this sort is not incompatible with libertarianism. Moreover, no unilateral powers of acquisition can fail to consider the impact on the interests of others. Hence, a doctrine of appropriation must incorporate such a proviso. However, the several interpretations such a proviso can take on various dimensions will be either (...) implausible as a way of taking into consideration the interests of others, or unable to generate the kind and extent of property rights libertarians typically endorse.

The Basic-Income Guarantee is a governmental programme of income redistribution that enjoys an increasing predicament among academic and political circles. Traditionally, the philosophical defence for this programme has been articulated from the standpoint of social liberalism, republicanism, or communism. Recently, however, libertarian philosopher Matt Zwolinski also tried to reconcile the Basic-Income Guarantee scheme with libertarian ethics. To do so, he resorted to the Lockean proviso: to the extent that the institutionalization of private property impoverishes certain people by depriving their (...) access to natural resources, these people deserve compensation and the most pragmatic way of providing this is through a Basic-Income Guarantee. This paper examines Zwolinski’s arguments and responds by demonstrating that the Basic-Income Guarantee is incompatible with libertarian ethics: the current levels of poverty are not caused by the institutionalization of private property and the Basic-Income Guarantee does not constitute a pragmatic approach to eradicate poverty.

The topic of this paper is the foundation for individual rights proposed by David Gauthier in his seminal 1986 book Morals by Agreement, and particularly the role of conception of rationality in this foundation. The foundation of rights is a part of Gauthier’s broader enterprise: to ground morals in rationality – more specifically, in the economic conception of rationality. Because of the importance of this conception for the whole of Gauthier’s project, we reconstruct first the conception of rationality which can (...) be found in decision theory and game theory, presenting simultaneously in a relatively non-technical way some basic concepts of the aforementioned disciplines. We proceed then to reconstruction of the foundation of rights itself – it turns on Gauthier’s interpretation of the so-called “Lockean proviso.” Lastly, we turn to the connection between rationality and foundation of rights. It is to be found in the narrow compliance – the disposition to enter only into cooperation which satisfies conditions of fairness set out in part by the Lockean proviso. (shrink)

This article argues for a social proviso concerning capital endowments that is analogous to Locke's original proviso on access to productive natural capital.

The neo-Lockean justification of the highly unequal distribution of income in capitalist societies is based upon two key premises: that people are the rightful owners of their labor and talents, and that the external world was, in the state of nature, unowned, and therefore up for grabs by people, who could rightfully appropriate parts of it subject to a ‘Lockean proviso.’ The argument is presented by Nozick. Counter-proposals to Nozick’s, for the most part, have either denied the premise (...) that people should morally be viewed as the owners of their talents, or have challenged Nozick’s Lockean proviso.Rawls, and to a more limited extent Ronald Dworkin, deny self-ownership. As Rawls writes: ‘…the difference principle represents, in effect, an agreement to regard the distribution of natural talents as a common asset … The naturally advantaged are not to gain merely because they are more gifted, but only to cover the costs of training and education and for using their endowments in ways that help the less fortunate as well. No one deserves his greater natural capacity nor merits a more favorable starting place in society.’ Behind the Rawlsian veil of ignorance, those who deliberate about justice are deprived of knowledge about characteristics whose distribution is morally arbitrary. In Dworkin’s proposal for resource egalitarianism, agents calculate the insurance policy they would hypothetically ask for, were they denied knowledge of what talents they will draw in the birth lottery. Compensation for unequal talents is, according to Dworkin, properly made by taxing and transferring income according to the way it would have been distributed as a consequence of such insurance. Dworkin’s veil of ignorance is thin, because agents in the appropriate posture for deliberating about income distribution know their preferences and attitudes toward risk, but not their talents. For both Rawls and Dworkin, the self-ownership premise is challenged by constructing a veil of ignorance in which people are deprived of knowledge of certain personal characteristics, knowledge of which would bias their opinions, from a moral viewpoint.

Resumen Este trabajo revisa algunas de las objeciones más frecuentes contra la versión que Nozick ofrece de la estipulación lockeana. Se detiene especialmente en dos de ellas: aquella que afirma que la estipulación es contraproducente y aquella que, por el contrario, sostiene que es insuficiente. Se rechazarán ambas críticas. La primera porque pasa por alto la distinción que Nozick hace entre no disminuir las oportunidades de usar un bien y las oportunidades de apropiárselo; la segunda porque asume erróneamente que la (...) línea de base de la estipulación se encuentra siempre en el estado de naturaleza. Finalmente se ofrece una formulación del principio de justicia en la adquisición que recoge las restricciones de estipulación.This paper reviews some of the most frequent objections against Nozick's version of Lockean Proviso. In particular, it examines two of them: the one that affirms that the stipulation is self-defeating and the one that, on the contrary, maintains that it is insufficient or to weak. Both criticisms are rejected. The first because it ignores Nozick's distinction between not diminishing the opportunities to use a specific good and the opportunities to appropriate it; the second because it erroneously assumes that the baseline of the stipulation is always in the state of nature. Finally, a formulation is offered on the principle of justice in acquisition that includes the stipulation restrictions. (shrink)

In an important recent article, "Contemporary Property Rights, Lockean Provisos, and the Interests of Future Generations, "Clark Wolf argues that sometimes the interests of future generations should take precedence over the claims of current property rights holders. Wolfs arguments concentrate on the genesis and nature of defensible property rights in various natural resources, and on the conditions under which morally unacceptable harm is caused to others. In this paper I explore two central sets of issues. First, I investigate (...) how the argument holds up when labor is involved in discovering, developing, or preparing natural resources for appropriation. I consider some persuasive reasons why one might think Wolfs arguments lose force in such cases. I also indicate how to accommodate these concerns without diminishing the force of Wolf s main arguments. Second, I show how either the examples Wolf uses do not support the conclusion he is pressing, or the argument has extremely far-reaching implications. I argue that either of these conclusions is problematic for Wolfs argument as thus far developed. (shrink)

This book develops a liberal theory of justice in exchange. It identifies the conditions that market exchanges need to fulfill to be just. It also addresses head-on a consequentialist challenge to existing theories of exchange, namely that, in light of new harms faced at the global level, we need to consider the combined consequences of millions of market exchanges to reach a final judgment about whether some individual exchange is just. The author argues that, even if we accept this challenge, (...) the effect of it is minimal. For different reasons, normatively problematic collective market outcomes like externalities, monopolies, violations of the Lockean proviso, inequality, and commodification do not pose particular problems to the justice of market exchanges. He outlines the various conditions a market exchange needs to fulfill to be considered just from a liberal background and in light of the new harms. Ultimately, he shows, it is not the market which is to blame; if we want to tackle issues like global warming or global economic injustice, we should not blindly follow the intuition that we best restrain and regulate markets. Commutative Justice is unique in its focus on justice in exchange rather than on end-state distributive justice, and the way in which it addresses the new harms we are facing today. It will be of interest to researchers and advanced students in philosophy, politics, and economics who are working on questions of economic justice. (shrink)

In this paper I argue that the potentially environmentally destructive scope of a libertarian property rights regime can be narrowed by applying reasonable limits to those rights. I will claim that excluding the right to destroy from the libertarian property rights bundle is consistent with self-ownership and Robert Nozick’s interpretation of the Lockean proviso.

The Lockean theory of property licenses unilateral appropriation on the condition that there be ‘enough, and as good left in common for others’. However, the meaning of this proviso is all but clear. This article argues that the proviso is centered around the Lockean theory of freedom. To be free, I argue, we must be ‘non-subjected’ in the exercise of our rights, including our rights to appropriate. We enjoy such freedom only when the ability to exercise our rights (...) does not depend on others. That can obtain if literally enough and as good is left in common. But it can also obtain in other ways, for example through competitive labour markets. The latter offer something as good as ‘enough and as good’. (shrink)

Under what circumstances can people convert natural resources into private property? John Locke famously answered this question by positing what has become known as the _Lockean proviso_: a person has the power to unilaterally appropriate natural resources ‘at least where there is enough and as good left in common for others’. This Lockean proviso has been widely embraced by right-libertarians who maintain that a relevant act appropriates only if others are not left worse off. However, this proviso is multiply (...) ambiguous with there being various ways of specifying its distinct elements. Daniel Attas has argued that all proposed specifications render the proviso either implausible or unsatisfied. However, there are three seemingly plausible specifications that he either fails to consider or does not adequately address. This paper attempts to show that these specifications are either unacceptable, go unsatisfied, or fail to support right-libertarianism. (shrink)

When it comes to specifying the moral duties we bear towards future generations, most political philosophers position themselves on what could be regarded as a safe ground. A variant of the Lockean proviso is commonplace in the literature on intergenerational justice, taking the form of an obligation to bestow upon future people a minimum of goods necessary for reaching a certain threshold of well-being (Meyer, 2017). Furthermore, even this minimum is often frowned upon, given the non-identity problem and the (...) challenges this presents to the topic of justice between generations. Additional issues are raised at the level of non-ideal theory, the most significant being the problem of non-compliance (Gosseries and Meyer, 2009).In this paper I intend to probe the limits of “practical political possibility” (Rawls 1999), by inquiring whether embracing the sufficiency view (Frankfurt, 1987; Crisp, 2003; Benbaji, 2005) as a distributive pattern and capabilities as a metric can lead to more burdensome obligations for present generations. More specifically, I try to show that we have a duty to invest in research that aims at prolonging the lifespan of humans (the idea can already be found in the sufficientarian literature, for instance in Farrelly, 2007). Moreover, given the Earth’s limited resources, we ought to encourage the terraforming of other planets in order to make them inhabitable for (future) people.I argue that these two seemingly far-fetched projects are in fact worthwhile goals to pursue on the one hand, and moral obligations on the other hand. Nonetheless, they are not the only ones we ought to take on; for instance, we must simultaneously pursue them and try to improve the prospects of those who fall under a sufficiency threshold here and now. That is, specifying these (prima facie) duties towards future generations is connected with stronger obligations towards the current generation.Towards the end of the paper I engage in a discussion regarding the role of the feasibility constraint in a theory of justice, as rationales pertaining to feasibility are perhaps going to be the most recurrent criticisms raised against my proposal. To that end, I defend limitarian policies, which aim at setting an upper limit to how much money individuals are allowed to possess (Robeyns, 2017; Volacu and Dumitru, 2019). (shrink)

I argue that Robert Nozick, in his well-known book “Anarchy, State, Utopia”, is working with Locke’s notion of the natural right to property merely instrumentally. I use the term “instrumentally” in the sense that the pieces of the source are not used within the context of the original work but are used atomically to support one’s argument or theory. Instrumental use of Locke’s theory causes incoherence in his theory. This paper introduces the incoherence in the question and explains how this (...) incoherency is inherent to Nozick’s interpretation and usage of Lockean Proviso. (shrink)

This symposium paper for the APA analyzes Locke's labor theory of property acquisition as a formal argument – or set of alternative arguments – and shows how several of them are indeed sound, if appropriately limited by what amounts to a social welfare proviso. That proviso is, however, strong enough to limit the acquisition of private property in a significant way. The argument here anticipates fuller and more decisive ones in later work by the same author.

This paper examines the question whether, and to what extent, John Locke’s classic theory of property can be applied to the current debate involving intellectual property rights (IPRs) and the information commons. Organized into four main sections, Section 1 includes a brief exposition of Locke’s arguments for the just appropriation of physical objects and tangible property. In Section 2, I consider some challenges involved in extending Locke’s labor theory of property to the debate about IPRs and digital information. In Section (...) 3, it is argued that even if the labor analogy breaks down, we should not necessarily infer that Locke’s theory has no relevance for the contemporary debate involving IPRs and the information commons. Alternatively, I argue that much of what Locke has to say about the kinds of considerations that ought to be accorded to the physical commons when appropriating objects from it – especially his proviso requiring that “enough and as good” be left for others – can also be applied to appropriations involving the information commons. Based on my reading of Locke’s proviso, I further argue that Locke would presume in favor of the information commons when competing interests (involving the rights of individual appropriators and the preservation of the commons) are at stake. In this sense, I believe that Locke offers us an adjudicative principle for evaluating the claims advanced by rival interests in the contemporary debate about IPRs and the information commons. In Section 4, I apply Locke’s proviso in my analysis of two recent copyright laws: the Copyright Term Extension Act (CTEA), and the Digital Millennium Copyright Act (DMCA). I then argue that both laws violate the spirit of Locke’s proviso because they unfairly restrict the access that ordinary individuals have previously had to resources that comprise the information commons. Noting that Locke would not altogether reject copyright protection for IPRs, I conclude that Locke’s classic property theory provides a useful mechanism for adjudicating between claims about how best to ensure that individuals will be able to continue to access information in digitized form, while at the same time also allowing for that information to enjoy some form of legal protection.

Offers a reconstruction of John Locke's voluntaristic theory of legitimate political authority with the aim of overcoming the following two problems with tacit consent via residence: that it fails to bind either because it is unfreely given or because it is offered in circumstances of inequality. Builds on the author's defence in Ch. 1 of an egalitarian version of the Lockean proviso to remedy these problems and endorses a highly voluntaristic, pluralistic, and decentralized account of legitimate political authority.

Libertarianism holds that agents initially fully own themselves. Lockean libertarianism further holds that agents have the moral power to acquire private property in external things as long as a Lockean Proviso—requiring that “enough and as good” be left for others—is satisfied. Radical right-libertarianism, on the other hand, holds that satisfaction of a Lockean Proviso is not necessary for the appropriation of unowned things. This is sometimes defended on the ground that the initial status of external resources as (...) unowned precludes any role for a Lockean Proviso. I shall show that this is a bad argument. Although I would argue that satisfaction of a Lockean Proviso is indeed a necessary condition for the appropriation of unowned things, I shall not attempt to establish that here. My goal here is more modest: to rebut one argument against the Lockean Proviso. (shrink)

Capitalism is often defended by appeals to natural rights: only in a free market, it is said, are people protected from the illegitimate intrusions of others. Coercion, either to prevent exchanges or to redistribute wealth, violates people's rights. But much of the property people have acquired came not from their own effort or the efforts of those who gave them gifts, but instead was taken from nature. Thus the question I propose to discuss in this paper: How is it that (...) an unowned natural resource can legitimately be acquired for private benefit? Much thought has been given by libertarian defenders of capitalism to justifying the claim that, once owned, property cannot be taken without its owner's consent. Relatively little attention has been paid, however, to how the original acquisition can be justified. Indeed, I argue here that if one approaches the problem of resource appropriation from the perspective of the Lockean ‘proviso,’ that enough and as good must be left in common, then the typical method of acquiring property under capitalism is unjust. Libertarians must either give up the individualistic, state of nature approach to economic justice or admit that appropriation of natural resources requires compensation of people who do not get a share of the resource.

Left-libertarianism comes in two main varieties: equal share and equal opportunity for well-being. Although equal share left-libertarians have supported a basic income guarantee, its equal opportunity counterparts either ignore a basic income in their theorizing or reject it. This article offers four reasons why left-libertarians should consider a basic income as a way to promote equality of opportunity for well-being: a basic income enhances self-respect, a basic income opens up the possibility of personal projects beyond traditional employment, a basic income (...) protects negative freedom, and a basic income minimizes potential for abuses and mistakes of centralized authorities. Peter Vallentyne’s objection to basic income is also considered. His asset-oriented account of the Lockean proviso is rejected in favor of an equality-promoting account that requires a substantial basic income. (shrink)

In "Morals by Agreement", David Gauthier attempts to derive property rights from a moral principle called the Lockean proviso. The derivation fails, and the true implications of the moral principles which Gauthier invokes are quite different. These principles imply that persons have extensive liberties to use physical materials, but relatively few rights against interference by others in this use. Robert Nozick argues for an extensive system of property rights in "Anarchy, State, and Utopia"; his argument fails for similar reasons.

G.A. Cohen was perhaps libertarianism’s most formidable critic. In Self-Ownership, Freedom, and Equality he levels several strong criticisms against Robert Nozick’s theory put forth in Anarchy, State, and Utopia. In this paper, I counter several of Cohen’s criticisms. The debate operates at three stages: self-ownership, world-ownership, and initial acquisition. At the first stage, Cohen does not attempt to refute self-ownership, but weaken its force in providing moral grounds for capitalism. Here I argue that Cohen’s attempt to overturn Nozick’s slavery argument (...) is unsuccessful because partial-slavery, while normatively different from full-slavery, is still normatively wrong. At the second stage, Cohen argues for a joint-ownership view of the world’s resources. In particular, he claims that self-ownership is rendered merely formal in a jointly-owned world and in a capitalist world. To rebut this challenge I show that even if Cohen is right about this, libertarian self-ownership is only formal in Cohen’s peculiar case where only two people exist and one owns everything. In contrast, self-ownership in a jointly-owned world is formal in all cases. Lastly, at the third stage, Cohen argues against Nozick’s interpretation of the Lockean proviso, claiming that it is impossible to satisfy. Granting Cohen’s argument here, I go on to defend Jan Narveson’s no-proviso view of acquisition from Cohen’s thus far unanswered criticism. I show that significantly, in his critique, Cohen equivocates between positive and negative rights. Taken jointly, my responses at these three stages ground the anti-egalitarian conclusion that, in Cohen’s words, ‘[e]xtensive inequality of condition is unavoidable, or avoidable only on pain of violating people’s rights to themselves and to things.’ The sequence, then, is from self-ownership, to world-ownership, via initial acquisition.
