The scope of libertarian law is normally limited to the application of the non-aggression principle (NAP), nothing more and nothing less. However, judging when the NAP has been violated requires not only a conception of praxeological notions such as aggression, but also interpretive understanding of what synthetic events count as the relevant praxeological types. Interpretive understanding—or verstehen—can be extremely heterogeneous between agents. The particular verständnis taken by a judge has considerable moral and political implications. Since selecting a verständnis is pre-requisite to applying the NAP, the NAP itself cannot tell us which one we ought morally to choose. Therefore the application of the NAP calls on moral and political considerations outside of the NAP itself. Since some of these are more consistent with an endorsement of the NAP than others, libertarianism is not a “thin” commitment to the NAP alone, but a “thick” commitment to the NAP and other supporting moral and political considerations.

Many libertarians ground their theory of justice in a non-aggression principle. The NAP is often the basis for the libertarian condemnation of state action – that it is necessarily aggressive and therefore unjust. This approach is often criticised insofar as it defines aggression, in part, as the violation of legitimate property rights, and is therefore parasitical upon a prior – and unjustified – theory of property. While it is true that libertarians who defend the NAP sometimes fail to give a satisfactory account of its relationship to libertarian property rights, such an account is in fact available. A commitment to property rights and to non-aggression can both be grounded in a commitment to non-interference. Such a principle, then, brings together the NAP and the theory of property it is parasitical upon, thus saving the unity and austerity of the overall approach.

There is a basic methodological difference in the way anarchists and non-anarchists think about politics, often more implicit than explicit. Anarchists see politics and justice as being concerns of social institutions, norms, and relations generally – both inside and outside the state. Much of academic political philosophy talks of politics and justice as if they are definitionally concerns about what states should do, or our relationships with each other through the state. In this chapter, we argue that the anarchists are on the right side of this difference. We call the insight that undergirds the anarchists’ understanding of politics and justice “methodological anarchism.” We seek to exorcise the policy framework in favor of methodological anarchism. Indeed, we believe it should be embraced by all political philosophers, not only the anarchists among their ranks. Political philosophers ought to abstain from the policy framework for two reasons. Firstly, it is analytically impoverished inasmuch as, when followed to its logical conclusion, it is unable to engage with enormous areas of analysis that are relevant to what makes a society just or unjust. Secondly, it instills subtle prejudice against other important approaches to mitigating injustice that are unconcerned with public policy. This also carries the danger of lending ideological support for existing injustices and thereby entrenching them. Accepting our critique of the policy framework and adopting methodological anarchism does not necessarily require the acceptance of any kind of substantive political anarchism. But it does mean thinking a bit more like an anarchist about how to make society more just – thus our characterization of it as “methodological.”

Hillel Steiner argues that a necessary and sufficient condition for the compossibility of a set of rights is that those rights be extensionally differentiable. However, given that two or more actions can extensionally overlap without thereby being mutually unperformable, if such actions are specified in the relevant rights, then those rights will not be incompossible, notwithstanding their extensional overlap. The set of compossible sets of rights then is greater than the subset of extensionally differentiable rights, and extensional differentiability is a sufficient but unnecessary condition of compossibility.

Lockean approaches to property take it that persons can unilaterally acquire private ownership over hitherto unowned resources. Such natural law accounts of property rights are often thought to be of limited use when dealing with the complexities of natural resource use outside of the paradigm of private ownership of land for agricultural or residential development. The tragedy of the commons has been shown to be anything but an inevitability, and yet Lockeanism seems to demand that even the most robust common property arrangements be converted to privatized units. This often motivates a move away from natural law in the moral analysis of property rights. I argue however that it is not the deontological nature of Lockean principles that are at fault, but rather the manner of their application. Lockean theory often exhibits a bias in favour of private property: assuming that only private property can protect one’s interest in autonomy, and therefore asserting that each individual has a power of private acquisition. Starting with a claim against interference however enables us to mould the appropriate property rights to each individual’s particular interest in autonomy. This sometimes leads to private ownership, but often leads to various forms of commons.

In this paper I criticize a growing movement within public policy circles that self-identifies as neoliberal. The issue I take up here is the sense in which the neoliberal label signals a turn away from libertarian political philosophy. The are many import ant figures in this movement, but my focus here will be on Will Wilkinson of the Niskanen Center, not least because he has most prolifically written against libertarian political philosophy. Neoliberals oppose the idea that the rights that libertarianism claims people have are useful guides for making the world a freer place because they forestall too much governmental/democratic political action that they purport to be necessary for increasing freedom. Wilkinson mistakenly takes libertarianism to be a set of ideal public policies for achieving a perfectly free society. If it were, he would be right to turn away from it. But placing rights to freedom at the center of their theory of justice does not commit libertarians to an all-or-nothing approach to political change. Consequences and strategy matter – particularly in a non-ideal world – without abandoning the idea that each individual has a right to freedom. In mistaking libertarian moral claims as a set of policy prescriptions, Wilkinson complains that idealistic policy prescriptions not only fail to take account of how those who disagree will respond to such policies if implemented, but also thereby undermines the justice of those policies in the first instance. Wilkinson proposes that change in the direction of freedom must go through the proper channels of actually-existing democratic legitimacy. It as this stage that Wilkinson’s project comes into direct conflict with libertarianism. Whilst libertarianism is not committed to any particular method of creating a free society under non-ideal conditions, and therefore does not rule out democratic political activism as one among many means of doing that, it cannot be committed to the permanence of democratic political authority, and this is what Wilkinson’s neoliberalism demands above all else. It turns out that Foucault’s characterization of neoliberalism long ago is still accurate to Wilkinson’s own view: that neoliberalism is not about creating a society of free individuals, it is about designing the state apparatus in ways that are inspired by the workings of free society – it is about legitimizing the chains, not breaking them. Neoliberalism is not a pragmatic alternative to libertarianism, but rather a gross misapplication of it.

This book gives an account of a full spectrum of property rights and their relationship to individual liberty. It shows that a purely deontological approach to justice can deal with the most complex questions regarding the property system. Moreover, the author considers the economic, ecological, and technological complexities of our real-world property systems. The result is a more conceptually sound account of natural rights and the property system they demand. If we think that liberty should be at the centre of justice, what does that mean for the property system? Economists and lawyers widely agree that a property system must be composed of many different types of property: the kind of private ownership one has over one's person and immediate possessions, as well as the kinds of common ownership we each have in our local streets, as well as many more. However, theories of property and justice have not given anything approaching an adequate account of the relationship between liberty and any other form of property other than private ownership. It is often thought that a basic commitment to liberty cannot really tell us how to arrange the major complexities of the property system, which diverge from simple private ownership. Property and Justice demonstrates how philosophical rigour coupled with interdisciplinary engagement enables us to think clearly about how to deal with real-world problems. It will be of interest to political philosophers, political theorists, and legal theorists working on property rights and justice.

Ben Bryan argues that the strongest challenge to natural rights theory is to explain how it overcomes the Problem of Authority. Given that our natural rights are multiply realisable by a range of equally reasonable social conventions, how or why ought one particular realisation have authority? I argue that Thomistic and Kantian solutions to this problem do not count as solutions from natural rights theory, and therefore offer my own solution. When theories of natural rights describe the rights we have in terms that refer not only to moralised act-types, but rather, tell us which non-moralised act-types ought to be moralised in the relevant way, they avoid the Problem of Authority altogether. Such theories of natural rights are singularly realisable at the level of regulative conventional rules, and only multiply realisable at the level of constitutive conventional rules. The latter form of multiple realisability does not raise the Problem of Authority.
