What attitude would a just state take to the inheritance of property? Would confiscatory taxes on the estate of the deceased be morally acceptable, or would they represent some kind of wrong? While there is a good amount of political philosophical scholarship that considers the desirability of inheritance tax, there appears to be little that has considered it from the perspective of rights theory, asking what kind of thing a right to bequeath or to inherit would be, and whether those (...) putative rights are defeasible. I argue here that putative inheritance rights are best made sense of as interest-rights. However, while agents may have interests in bequest and inheritance, it is also plausible that the community as a whole has interests that would be served by a confiscatory inheritance tax; and if inheritors’ and testators’ interests are strong enough to generate a prima facie right, it is also plausible that the community would have a competing prima facie right. Importantly, there is reason to think that the community’s interests trump the testator’s and the inheritor’s; if there are thoroughgoing rights in respect of inheritance, it is not at all clear that a highly confiscatory tax would violate them.

Recently, Eric Mack, Edward Feser, and Daniel Russell have argued that self-ownership justifies a constraint on the use of property such that an owner’s use of property may not severely negate the ability of others to interact with the world. Mack has labeled this constraint the self-ownership proviso. Adopting this proviso promises right-libertarians a way of avoiding the extreme implications of a no-proviso view, while maintaining a consistent and cohesive position. Nevertheless, I argue that self-ownership cannot ground the constraint on (...) property use that Mack, Feser, and Russell think that it can. (shrink)

A number of hugely valuable natural resources fall outside of the borders of any nation state. We can legitimately expect political theory to make a contribution to thinking through questions about the future of these extraterritorial resources. However, the debate on the proper allocation of rights over these resources remains relatively embryonic. This paper will bring together what have often been rather scattered discussions of rights over extraterritorial resources. It will first sketch some early modern contributions to thinking through rights (...) over the ocean. It then discusses the guidance available within more contemporary contributions to debates on resources beyond the state. Finally, it concludes by emphasising the key questions with which future work on this topic must engage. (shrink)

This paper discusses what implications global luck egalitarianism (GLE) has for border control. Some authors suggest that an open‐borders policy follows from GLE. The idea is that various unchosen inequalities inevitably follow from differences in birthplace, such that GLE will always have principled reason to condemn closed borders. Others are skeptical of the assumption that GLE will have liberal implications for border control, because open borders may have other, adverse effects that outweigh the reductions in unjust inequality. Against such skeptics, (...) we argue that GLE will (typically) have quite liberal implications for border control. However, this connection is not a principled one: Whether (and to what extent) GLE favors opening or closing borders will depend upon empirical circumstances. (shrink)

The central insights of Philip Pettit’s republican account of liberty are that (1) freedom consists in the absence of domination and (2) non-domination is not reducible to what is commonly called ‘negative liberty’. Recently, however, Matthew Kramer and Ian Carter have questioned whether the harms identified by Pettit under the banner of domination are not equally well accounted for by what they call the ‘pure negative’ view. In this article, first I argue that Pettit’s response to their criticism is problematic (...) insofar as it produces the following dilemma: either Pettit must concede that domination which one regards as consistent with one’s own best interests does not limit one’s freedom or he must embrace the implication that one can be forced to be free, a result he explici tly wants to avoid. Second, I argue that, despite the inadequacy of Pettit’s response, he is ultimately right in thinking that domination and negative liberty are sometimes compatible. My central contention, then, is that neither Pettit’s non-domination view nor Carter and Kramer’s pure negative view are able to account for the loss of liberty one suffers under conditions of domination.

Leistungssportlerinnen, die in populären Sportarten erfolgreich sind, kommen in den Genuss hoher Einkommen und großen sozialen Ansehens. Gleichzeitig ist ihr Erfolg von Voraussetzungen abhängig, die zu einem signifikanten Teil von ihrem Genotyp bestimmt werden. Diesen Sportlern werden also durch gesellschaftliche Prozesse substantielle Vorteile aufgrund von Eigenschaften zuteil, auf deren Vorhandensein sie keinen Einfluss haben. Wir untersuchen, wie wir vor dem Hintergrund verschiedener Gerechtigkeitsvorstellungen mit diesem Phänomen umgehen sollten. Wir argumentieren, dass die konsistente Berücksichtigung von Intuitionen zur gerechten Güterverteilung an Wettkämpferinnen (...) eine deutliche Ausweitung des Einsatzes von Wettkampfklassen erfordert. Die bestehenden Ungleichverteilungen lassen sich nicht allein mit Verweis auf ein Recht auf Selbsteigentum rechtfertigen. Sie verursachen auch keine Verbesserungen der Lage von besonders schlecht gestellten Individuen im Wirkungsbereich des Leistungssports, auf die zugunsten ihres Weiterbestehens verwiesen werden könnte. Trotz des erheblichen Aufwandes und der deutlichen Veränderungen im Charakter des Leistungssports, die mit der vorgeschlagenen Differenzierung von Wettkampfklassen einhergingen, ist diese Maßnahme geboten.

Libertarianism is a controversial political theory. But it is often presented as a resting upon a simple, indeed commonsense, moral principle. The libertarian “Non-Aggression Principle” (NAP) prohibits aggression against the persons or property of others, and it is on this basis that the libertarian opposition to redistributive taxation, legal paternalism, and perhaps even the state itself is thought to rest. This paper critically examines the NAP and the extent to which it can provide support for libertarian political theory. It identifies (...) two problems with existing libertarian appeals to the NAP. First, insofar as libertarians employ a moralized understanding of aggression, their principle is really about the protection of property rights rather than the prohibition of aggression. Second, the absolutist prohibition on aggression, which libertarians typically endorse and which is necessary to generate strongly libertarian conclusions, is grossly implausible. The paper concludes by setting forth a version of the NAP that does not suffer from these problems. It argues that this more moderate and defensible version of the NAP still has important libertarian implications, but that a full defense of libertarianism cannot rely upon appeals to non-aggression alone.

The Body Ownership Thesis states that each person owns her body. I address a prominent objection, the Generation Problem: the Body Ownership Thesis apparently implies that parents own their children: as we own the fruit of our property, if a parent owns her own body, she must own her child and her child's body. I argue that a person does not own the fruit of her property when that fruit is a person or the body of a person. Persons have (...) conclusive title to their bodies, but only defeasible title to the fruits of their bodies. (shrink)

If one values freedom, what sort of regime of property should one favor: libertarianism, socialism, or something else again? Debate on this topic has been hampered by a failure to distinguish freedom and liberty, which are both of great value, but can come into conflict. Furthermore there are many similar concepts—distinct from both liberty and freedom, yet each representing something we rightly value—which may also come into conflict with each other and with freedom and liberty. Consequently the question posed above (...) has no easy answer. (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)

From a left-libertarian perspective, it seems almost impossible for states to acquire political authority. For that reason, left-libertarians like Peter Vallentyne understandably hope that states without political authority could nonetheless implement left-libertarian justice. Vallentyne has argued that one can indeed assess a state’s justness without assessing its political authority. Against Vallentyne, I try to show that states without political authority have to be judged unjust even if they successfully promote justice. The reason is that institutions can be unjust independently from (...) what they achieve or do: they can be ‘intrinsically unjust’. Institutions, I argue, are intrinsically unjust when they have legal liberties and powers without having the corresponding moral liberties and powers. States without political authority are intrinsically unjust in that sense. Hence the issues of a state’s justness and a state’s political authority cannot be dealt with separately. This is a problem not only for left-libertarians but for ‘philosophical anarchism’ more generally. (shrink)

This paper recasts an old objection to the will theory in the light of recent attempts to defend that theory, notably by Nigel Simmonds and Hillel Steiner. It enlists the idea of duties of care—effectively restrictions over legal officials’ discretionary exercise of powers—to form a dilemma for such theorists: either legal officials’ discretion over powers is restricted by duties of care for the unempowerable, or it is not. If their discretion is unrestricted, then the will theory is insensitive to the (...) (values of the) lives of the unempowerable, in virtue of the fact that these lives are viewed as not meriting direct normative consideration. If, on the other hand, their discretion is restricted by duties of care, then the will theory has no argumentative resources within its conceptual apparatus to ascribe or justify them. It is therefore incomplete as a theory of rights. (shrink)

Scholars concerned with abuses of the “resource privilege” by the governments of developing states sometimes call for national sovereignty over the natural resources that lie within its borders. While such claims may resist a key driver of the “resource curse” when applied to mineral resources in the ground, and are often recognized as among a people’s territorial rights, their implications differ in the context of climate change, where they are invoked on behalf of a right to extract and combust fossil (...) fuels that is set in opposition to global climate change mitigation imperatives. Moreover, granting full national sovereignty over territorial carbon sinks may conflict with commitments to equity in the sharing of national mitigation burdens, since much of the planet’s carbon sink capacity lies within territorial borders to which peoples have widely disparate access. In this paper, I shall explore this tension between a global justice principle that is often applied to mineral resources and its tension with contrary principles that are often applied to carbon sink access, developing an analysis that seeks to reconcile what would otherwise appear to be fundamentally incompatible aims.

Philosophical defenses of property regimes can be classified as supporting either a conservative politics of property rights—the political protection of existing property titles—or a radical politics of direct political intervention to redistribute property titles. Traditionally, historical considerations were used to legitimize conservative property‐rights politics, while consequentialist arguments led to radical politics. Recently, however, the philosophical legitimations have changed places. Conservatives now point to the beneficial economic consequences of something like the current private‐property regime, while radicals justify political redistribution as restitution (...) for historical misappropriations. This shift can be explained by such factors as the failure of state‐directed redistributions of property during the twentieth century to benefit the poor. But there are limitations to the usefulness of historical arguments for radicals, and of consequentialist arguments for conservatives: namely, the undeserving poor and the idle rich, respectively.

Hillel Steiner’s left-libertarian theory of justice is the most serious recent attempt to reconcile the ideals of equality and freedom. This attempt consists in an argument that a universal right to equal freedom, which in Steiner’s view means also a universal right to maximal freedom, implies a universal right to self-ownership and to an egalitarian share of the world’s natural resources. In this article, I argue that this argument fails on Steiner’s own terms. I argue that, on Steiner’s conceptions of (...) freedom, self-ownership, and an egalitarian share of the world’s natural resources, insofar as the right to equal freedom implies the right to self-ownership and to an egalitarian share of the world’s natural resources, it is incompatible with equality.

Freedom is one of the most important moral and political ideals. Questions concerning degrees of overall freedom are therefore of the utmost moral and political concern. To answer these questions we need to know how to measure degrees of overall freedom. This paper offers a novel defence of the partly evaluative approach to freedom measurement against a recent critique of it. According to the partly evaluative approach, the question of how free one is depends partly on the specific value of (...) the freedoms one possesses and partly on their physical extension. According to the critique, because of its reference to freedoms’ specific value, the partly evaluative approach fails to capture freedoms’ non-specific value, which is what it should capture. In this paper I argue that this critique is unfounded, by showing that even measures of more mundane things, which nevertheless, like freedom, present us with a commensuration problem, sometimes involve evaluative considerations similar to the ones that the partly evaluative approach invokes.

The most prominent theories of rights, the Will Theory and the Interest Theory, notoriously fail to accommodate all and only rights-attributions that make sense to ordinary speakers. The Kind-Desire Theory, Leif Wenar’s recent contribution to the field, appears to fare better in this respect than any of its predecessors. The theory states that we attribute a right to an individual if she has a kind-based desire that a certain enforceable duty be fulfilled. A kind-based desire is a reason to want (...) something which one has simply in virtue of being a member of a certain kind. Rowan Cruft objects that this theory creates a puzzle about the relation between rights and respect. In particular, if rights are not grounded in aspects of the particular individuals whose rights they are, how can we sustain the intuitive notion that to violate a right is to disrespect the right-holder? I present a contractualist account of respect which reconciles the Kind-Desire Theory with the intuition that rights-violations are disrespectful. On this account, respect for a person is a matter of acknowledging her legitimate authority to make demands on the will and conduct of others. And I argue that kind-based desires authorize a person to make demands even if they do not correspond to that person’s well-being or other non-relational features. (shrink)

Opponents of compulsory voting often allege that it violates a ‘right not to vote’. This paper seeks to clarify and defend such a right against its critics. First, I propose that this right must be understood as a Hohfeldian claim against being compelled to vote, rather than as a mere privilege to abstain. So construed, the right not to vote is compatible with a duty to vote, so arguments for a duty to vote do not refute the existence of such (...) a right. The right against compulsion is most easily defended within a liberal framework, hence its critics often appeal instead to a republican conception of freedom. In the latter part of the paper, I argue that even these republican arguments are inconclusive. Even non-dominating interference still conditions freedom, which may require justification. Further, citizens can live up to republican ideals, so long as they are vigilant; they need not actually vote. Thus, republican arguments fail to refute a right not to vote. (shrink)

This article provides a survey of key topics on just inheritance taxation. It does so by first presenting the main arguments in the debate. Here, I distinguish between arguments in the academic literature and the various arguments which have proven important in the public debate. Secondly, I outline four influential proposals when it comes to how inheritance should be taxed. Finally, I examine a recent controversy and point towards a number of themes that have not been sufficiently discussed.

G.A. Cohen has produced an influential criticism of libertarian‐ism that posits joint ownership of everything in the world other than labor, with each joint owner having a veto right over any potential use of the world. According to Cohen, in that world rationality would require that wealth be divided equally, with no differential accorded to talent, ability, or effort. A closer examination shows that Cohen's argument rests on two central errors of reasoning and does not support his egalitarian conclusions, even (...) granting his assumption of joint ownership. That assumption was rejected by Locke, Pufendorf and other writers on property for reasons that Cohen does not rebut. (shrink)

Political philosophers commonly tackle the issue of climate change by focusing on fundamental interests as a basis for human rights. This approach struggles, however, in cases where one set of fundamental interests requires one course of action, and another set of fundamental interests requires another course of action. This article advances an alternative response to climate change based on an account of global justice that gives weight to utilitarian, prioritarian, and luck egalitarian considerations. A practical application of this pluralistic account (...) is provided, which shows that it handles trade-offs between individuals’ interests in an appealing way, and that it supports an aggressive policy of climate change mitigation. This account provides a more plausible justification for rights against the harms of climate change. (shrink)

Corporate freedom is the freedom of a collective agent to perform a joint action. According to a reductive account, a collective or corporate agent is free exactly if the individuals who constitute the corporate agent are free. It is argued that individual freedoms are neither necessary nor sufficient for corporate freedom. The alternative account proposed here focuses on the performance of the joint action by the corporate agent itself. Subsequently, the analysis is applied to Cohen’s (1983) analysis of proletarian freedom. (...) Cohen claims that proletarians are individually free but collectively unfree to leave the proletariat. I argue that, pace Cohen, such a contrast between individual and collective freedom can only exist if collective freedom is interpreted in terms of corporate freedom. (shrink)

Common sense morality and legislations around the world ascribe normative relevance to biological connections between parents and children. Procreators who meet a modest standard of parental competence are believed to have a right to rear the children they brought into the world. I explore various attempts to justify this belief and find most of these attempts lacking. I distinguish between two kinds of biological connections between parents and children: the genetic link and the gestational link. I argue that the second (...) can better justify a right to rear.

I defend the idea that a liberal commitment to value neutrality is best honoured by maintaining a pure cardinality component in our rankings of opportunity or liberty sets. I consider two challenges to this idea. The first holds that cardinality rankings are unnecessary for neutrality, because what is valuable about a set of liberties from a liberal point of view is not its size but rather its variety. The second holds that pure cardinality metrics are insufficient for neutrality, because liberties (...) cannot be individuated into countable entities without presupposing some relevantly partisan evaluative perspective. I argue that a clear understanding of the liberal basis for valuing liberty shows the way to satisfying responses to both challenges. (shrink)

In contrast to eminent historical philosophers, almost all contemporary philosophers maintain that slavery is impermissible. In the enthusiasm of the Enlightenment, a number of arguments gained currency which were intended to show that contractual slavery is not merely impermissible but impossible. Those arguments are influential today in moral, legal and political philosophy, even in discussions that go beyond the issue of contractual slavery. I explain what slavery is, giving historical and other illustrations. I examine the arguments for the impossibility of (...) contractual slavery propounded in the Enlightenment and their offspring expounded in recent writings, including those by Barnett, Cassirer, Ellerman, Rawls, Roberts-Thomson, Satz and Steiner. I show that they involve confusions between abilities and rights, free will and freedom, directing and doing, what may be true sequentially and what may be true simultaneously, default rights and universal rights, impermissibility and impossibility, and metaphorical and literal uses of language.

An alleged moral right to informational privacy assumes that we should have control over information about ourselves. What is the philosophical justification for this control?

Various authors hold that what is wrong with risk imposition is that being at risk diminishes the opportunities available to an agent. Arguably, even when risk does not result in material or psychological damages, it still represents a setback in terms of some legitimate interests. However, it remains to be specified what those interests are. This article argues that risk imposition represents a diminishment of overall freedom. Freedom will be characterized in empirical terms, as the range of unimpeded actions available (...) to an agent. After briefly outlining the main characteristics of overall freedom as defended by Hillel Steiner and Ian Carter, the article shows that this notion is able to capture many of our intuitions about when and how risk imposition disadvantages an agent, without reference to welfare indicators. The article argues that if this non-welfarist perspective can be defended, then it would be easier to approach a number of applied questions about risk, including the questions of when risk imposition is permissible or legitimate, in which ways risk can be an object of distributive justice and how one can be compensated for being subject to a risk.

A good deal of political theory over the last fifteen years or so has been shaped by the realization that one cannot, and ought not, consider the distribution of resources within a country in isolation from the distribution of resources between countries. Thus, thinkers such as Charles Beitz and Thomas Pogge advocate extensive global distributive policies; others, such as Charles Jones and David Miller, explicitly reject the view that egalitarian principles of justice should apply globally and claim that national communities (...) have only duties to help other countries be viable economically and meet the basic needs of their members. In the global justice debate, pretty much all parties acknowledge that we have obligations of distributive justice to for-eigners. The question is how strong those obligations are, and in particular whether national boundaries can make any difference to the distribution of resources between members of different countries.

This paper aims to offer a plausible and renewed defence of the axioms of the already well-known account of political philosophy ‘luck egalitarianism’. By finding certain support not only in the Kantian moral programme but also in widely accepted intuitions of our time, it is contended that luck egalitarianism possesses sufficient justification to become an ethical guide at the global level, revealing plausibly the existence of a compelling positive moral duty to terminate global poverty and denouncing its toleration as nothing (...) but a matter of injustice. The arguments provided to embrace such a proposal are built upon the widely accepted claim in moral philosophy that ‘all persons are equal in fundamental moral worth’. From this standpoint, I argue that the luck egalitarian doctrine can not only satisfy such a claim to its ultimate consequences, but it also reasonably overcome its most severe challenges that have diminished its merits in recent times when it aspires to become a tenable theory of justice.

Republican freedom is freedom from domination juxtaposed to negative freedom as freedom from interference. Proponents argue that republican freedom is superior since it highlights that individuals lose freedoms even when they are not subject to interference, and claim republican freedom is more ‘resilient’. Republican freedom is trivalent, that is, it includes the idea that someone might be non-free to perform some actions rather than unfree, and in that sense everyone regards republican freedom as different from negative freedom. Trivalence makes republican (...) freedom moralized according to negative libertarians. Beyond that, negative libertarians argue that all the supposed advantages of republican freedom are compatible with those of pure negative-freedom measures. That is, losses and gains of republican freedom are captured in measures of pure negative freedom, and any protection for republican freedom also protects negative freedom, ensuring each is equally resilient. Since republican freedom has no advantages over negative freedom, but has other problems (is moralized and is trivalent), negative freedom is superior. I examine this debate in this article through the ‘coalition problem’ for republican freedom. The coalition problem is that since there is always a coalition of others who could dominate any agent in any sphere, all agents are subject to domination, and hence no one can ever have republican freedom. Pettit’s simple solution to this reductio ad absurdum distinguishes potential from actual coalitions. Individuals are only dominated by actual coalitions, and not by potential ones. The simple solution highlights moralization problems as it demonstrates that domination cannot be purely institutionally defined, but requires consideration of dispositions and expectations about others’ behaviour. I argue that the differences between the ‘free man’ and ‘unfree person’ paradigmatic to republican arguments is best captured not by the difference between domination and interference, but, rather, from familiar distinctions between different types of rights and freedoms. Resilience is a practical matter that might track some of these familiar distinctions. (shrink)

RÉSUMÉ: La notion de propriété de soi présuppose la définition des droits de propriété sur les ressources externes que le libertarisme de gauche limite habituellement aux ressources naturelles. Or, dans une économie spécialisée, la propriété de soi doitégalement être complétée par une définition des droits de propriété sur le surplus coopératif. S'il est cohérent, pour un libertarien de gauche, de considérer le surplus coopératif comme ressource externe et de le distribuer d'une manière égale, on doit en outre observer qu'une théorie (...) de la justice doit se prononcer sur les questions distributives dans plusieurs contextes. Articuler les différences entre ces contextes nous permet de préciser la relation que le libertarisme de gauche entretient avec d'autres théories de la justice.ABSTRACT: Any substantive notion of self-ownership presupposes well-defined property rights over external resources. Left-libertarians usually limit this category to natural resources. I argue that in a specialized economy, substantive self-ownership equally needs to be complemented by a definition of property rights to the cooperative surplus. The natural way for left-libertarianism to provide such a definition is to view the cooperative surplus as an external resource and to distribute it equally. The second part of the article makes the general point that a complete theory of justice needs to take a stance on distribution in various contexts. Articulating the differences between these contexts allows us to gain a better understanding of how left-libertarianism relates to other theories of justice. (shrink)

Governments must keep agricultural systems free of pests that threaten agricultural production and international trade. Biosecurity surveillance already makes use of a wide range of technologies, such as insect traps and lures, geographic information systems, and diagnostic biochemical tests. The rise of cheap and usable surveillance technologies such as remotely piloted aircraft systems presents value conflicts not addressed in international biosurveillance guidelines. The costs of keeping agriculture pest-free include privacy violations and reduced autonomy for farmers. We argue that physical and (...) digital privacy in the age of ubiquitous aerial and ground surveillance is a natural right to allow people to function freely on their land. Surveillance methods must be co-created and justified through using ethically defensible processes such as discourse theory, value-centred design and responsible innovation to forge a cooperative social contract between diverse stakeholders. We propose an ethical framework for biosurveillance activities that balances the collective benefits for food security with individual privacy: establish the boundaries of a biosurveillance social contract; justify surveillance operations for the farmers, researchers, industry, the public and regulators; give decision makers a reasonable measure of control over their personal and agricultural data; and choose surveillance methodologies that give the appropriate information. The benefits of incorporating an ethical framework for responsible biosurveillance innovation include increased participation and accumulated trust over time. Long term trust and cooperation will support food security, producing higher quality data overall and mitigating against anticipated information gaps that may emerge due to disrespecting landholder rights.

I defend nudging and jolting by distinguishing them from the sometimes oppressive means with which they can be implemented, by responding to some common arguments against nudging, and by showing (...) how respect for preferences over option sets and their aggregate properties may require the trimming of option sets, as well as helpful choice contexts.

1. Among the most striking features of the political arrangements on this planet is its division into sovereign states.1 To be sure, in recent times, globalization has woven together the fates of communities and individuals in distant parts of the world in complex ways. It is partly for this reason that now hardly anyone champions a notion of sovereignty that would entirely discount a state’s liability the effects that its actions would have on foreign nationals. Still, state sovereignty persists as (...) a political fact. The number of states has increased enormously due to upheavals of the 20th century, and there is nothing in principle morally wrong with the existence of states - or so we will assume.2 What must be explored, then, are the limits of normatively plausible sovereignty. How bad does a government have to be for outsiders to be allowed to interfere? What responsibilities does a country incur because of its contribution to global warming? What obligations arise through trading? In this paper, we explore another pertinent question: to what extent is a country allowed to influence who lives on its territory by regulating immigration? The angle from which we approach this question continues to be neglected even now that questions of global justice are receiving much attention. Immigration amounts to a change in political relationships as immigrants alter their standing within one community and acquire a status elsewhere. Yet it also amounts to an alteration in physical relationship, since they acquire a relationship to a territory, making a life for themselves with the resources offered by a part of the earth.3 We base our exploration of..
