In this dissertation, I investigate the implications of libertarian morality in relation to the problem of climate change. This problem is explicated in the first chapter, where preliminary clarifications are also made. In the second chapter, I briefly explain the characteristics of libertarianism relevant to the subsequent study, including the central non-aggression principle. In chapter three, I examine whether our individual emissions of greenhouse gases, which together give rise to climate change, meet this principle. I do this based on the (...) assumption that we are the legitimate owners of the resources we use in those activities. In the fourth chapter, I question this assumption and scrutinize libertarianism’s restrictions on appropriations of climate-relevant resources, which leads me to distinguish between some different versions of the libertarian view. Toward the end of the chapter, I also examine libertarianism’s answer to the political question regarding how emission rights should be distributed. The fifth chapter investigates libertarianism’s verdicts for mere risks of infringement, as stemming from people’s emissions and acts of appropriations. In chapter six, I investigate the libertarian right to self-defense against both the effects of climate change and other people’s climate-relevant activities. In chapter seven, I discuss two intergenerational issues related to climate change: what libertarianism says concerning future generations and how libertarianism might deal with the problem of historical emissions. The eighth chapter explores the implications of libertarianism regarding collective moral wrongdoing in connection to climate change. In chapter nine, I take a look at the libertarian room for governmental responses for tackling climate change. The tenth and final chapter is a summary. The overall conclusion of the dissertation is that libertarianism recommends that we reduce our emissions and decrease our extraction of natural resources such as forests and fossil fuels. Furthermore, governments are permitted to undertake some quite substantial actions in order to fight the causes of climate change. I end with some bottom-up reflections on what these conclusions might say about the plausibility of libertarianism. I claim that although libertarianism after all manages to explain some of our moral intuitions regarding climate change, it is questionable whether libertarianism’s explanation is better than those offered by alternative moral theories.

Murray N. Rothbard and Hans-Hermann Hoppe build their libertarian theory of justice on two axioms concerning self-ownership and homesteading, which are bolstered by two key arguments: reductio ad absurdum and performative contradiction. Each of these arguments is designed to demonstrate that libertarianism is the only theory of justice that can be justified. If either of these arguments were valid, it would prove the libertarian claim that the state is an unjust political arrangement. Giving due weight to the importance of the (...) libertarian anarchist claim, this article exposes and criticizes the arguments that substantiate it. (shrink)

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.

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)

Libertarianism holds that agents initially fully own themselves and have moral powers to acquire property rights in external things under certain conditions. It is normally advocated as a theory of justice in the sense of the duties that we owe each other. So understood, it is silent about any impersonal duties (i.e., duties owed to no one) that we may have.

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.

Hillel Steiner’s left-libertarian theory of justice is the most serious recent attempt to reconcile the ideals of (luck-egalitarian) 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 (luck-egalitarian) equality.

The argument from background justice is that conformity to Lockean principles of justice in agreements and transactions does not preclude the development of inequalities that undermine the freedom and fairness of those very transactions, and that, therefore, special principles are needed to regulate society's “basic structure.” Rawls offers this argument as his “first kind of reason” for taking the basic structure to be the primary subject of justice. Here I explore the background justice argument and its implications for questions about (...) the scope of distributive justice. As it turns out, the background justice argument can offer no independent support for conclusions about the scope of distributive justice. For the special principles that it justifies inherit their scope from conclusions that must be established or assumed in advance. These prior conclusions are precisely what is at issue in debates about global justice. (shrink)

In a recent review essay of a two volume anthology on left-libertarianism (edited by two of us), Barbara Fried has insightfully laid out most of the core issues that confront left-libertarianism. We are each left-libertarians, and we would like to take this opportunity to address some of the general issues that she raises. We shall focus, as Fried does much of the time, on the question of whether left-libertarianism is a well-defined and distinct alternative to existing forms of liberal egalitarianism. (...) More specifically, we shall address the following fundamental issues raised by Fried (and others): (1) Does the notion self-ownership have any determinate content? (2) What is the relation between self-ownership and world ownership? (3) How is left-libertarianism different from other forms of liberal egalitarianism (e.g., those of Rawls and Dworkin)? (shrink)

Tras comparar la concepción de Risse de Propiedad Común de la Tierra con otras alternativas teóricas de redistribución global o de reformulación de los derechos humanos en términos de membrecía , concluimos que PCT, como teoría de justicia distributiva global, defiende un umbral innecesariamente bajo; y como concepción de derechos humanos no fundamenta con robustez las garantías socioeconómicas. Finalmente, la especificación de los derechos humanos a partir de la membrecía global no es traducible a términos de «derecho a no-exclusión de (...) la nueva propiedad pública» , ya que la condición de subsistencia de los derechos humanos no implica necesariamente la condición de independencia del estatus de co-propietario original. Así pues, esta derivación contingente de los derechos humanos no cumple la condición de transitividad exigida por sus requisitos internos de justificación. (shrink)

In his left-libertarian theory of justice Hillel Steiner introduces the idea of conceiving our germ-line genetic information as a natural resource as a means to achieving luck-egalitarian equality. This idea is very interesting in and of itself. But it also has the potential of turning Steiner’s theory into a particularly powerful version of left-libertarianism, or so I argue in the first part of this paper. In the second part I critically examine this idea. I show why, in contrast to what (...) Steiner claims, this idea requires us to evaluate not only the pieces of GLGI that we have used, but rather all the pieces of GLGI that our bodies deliver throughout our lives. Then I argue that besides the immense technical difficulties involved in meeting this requirement, which we may overcome in the future, there is also a substantive reason why we cannot meet this requirement. The relevant value of any given piece of GLGI depends on the way it would interact with another piece of GLGI of the opposite sex in a reproductive process. But there is no way of determining which pieces of GLGI should be assigned to each other for the purpose of this evaluation. (shrink)

L’objectif de ce papier est double : d’une part défendre l’idée que la théorie de la justice proposée par le libertarisme de gauche fait de la figure de l’entrepreneur une éminence grise, centrale, bien que très rarement mentionnée et, d’autre part, discuter les critiques qui ont été adressées à cette théorie de la justice.
