Libertarianism is a theory of justice that places significant moral weight on exclusive property rights. On this basis, many libertarian philosophers, from Robert Nozick to Michael Huemer, criticize any form of income redistribution. Ironically, some libertarians, following Philippe Van Parijs, Matt Zwolinski, and Charles Murray, have supported the introduction of an unconditional basic income. This essay seeks to prove that this support is not just a political compromise. By contrast, libertarian justice advocates have a strong moral basis for supporting income (...) redistribution in the form of unconditional cash payments. This essay explores one such reason, the Lockean proviso. The Lockean proviso is a moral requirement for the appropriation of unowned resources to leave “enough and as good” for others. There are many interpretations of the Lockean proviso, but the most ambitious are the egalitarian proviso and the sufficiency proviso. Each of them, but for different reasons, requires the introduction of a basic income. The egalitarian proviso establishes the equal rights of all people to natural resources, and therefore requires that all benefits from the ownership of natural resources be shared egalitarianly — in the form of unconditional equal payments. The sufficiency proviso establishes some threshold of sufficiency, and then imposes a restriction on exclusive property rights so that they can’t prevent redistribution in order to raise all people to the threshold of sufficiency. However, while both provisos require a basic income, they diverge on three important dimensions in assessing this basic income: applicability, taxable base, and amount of cash payments. (shrink)

Distributive justice is one of the central questions of contemporary moral and political philosophy. Discussions on this topic are often presented as a confrontation between two groups of thinkers: libertarians and luck egalitarians. The former emphasize the dependence of the existing distribution on the individual choice and personal responsibility of people, and therefore are skeptical about various redistribution programs. The latter, on the contrary, emphasize the influence of morally arbitrary luck on the economic situation of people, and therefore welcome redistributive (...) measures to compensate for this brute luck. Left-libertarian claims to reconcile these two types of moral considerations. The classical left-libertarian point of view seeks to offset the influence of brute luck through an egalitarian distribution of the benefits of owning natural resources that are independent of anyone’s choice and responsibility. However, this position does not sufficiently take into account the influence of other factors of brute luck and, in particular, genetic endowments on the distribution of economic wealth. This article discusses three approaches that allow left-libertarians to take into account the factor of genetic luck in interpersonal distribution. First, it is Hillel Steiner’s proposal to attribute genetic information to natural resources, the benefits of which are subject to egalitarian redistribution. Second, it is the concept of equal opportunity for welfare by Peter Vallentyne, Michael Otsuka and Eric Roark. Third, it is the universal dominance criterion of Philippe Van Parijs and Kasper Ossenblok. The first two approaches face a number of moral and practical difficulties, but the third approach is able to overcome them. Thus, the universal dominance criterion is the most promising way to reconcile left-libertarianism and justice in the distribution of genetic endowments. (shrink)

According to the sufficiency principle, distributive justice requires that everyone have some sufficient level of resources or well-being, but inequalities above this threshold have no moral significance. This paper defends a version of the sufficiency principle as the appropriate response to moral uncertainty about distributive justice. Assuming that the appropriate response to moral uncertainty is to maximize expected choiceworthiness, and given a reasonable distribution of credence in some familiar views about distributive justice, a version of the sufficiency principle strikes the (...) optimal balance between the competing moral risks posed by implementing these views. In particular, it avoids the moral risk posed by views like Nozick’s libertarianism, which forbid redistributive taxation even for the sake of helping to provide for people’s basic needs: failing to do the latter, if it turns out that justice does require it, would be very morally wrong. This “uncertainty argument” has the advantage of minimizing reliance on controversial intuitions about distributive justice, helps to specifying a non-arbitrary threshold for sufficiency, and shows that the substantive moral implications of moral uncertainty are not limited to high-stakes applied ethics issues such as abortion and vegetarianism but instead extend to an issue at the heart of political philosophy.

In this article, I propose a novel characterization of sufficientarianism. I argue that sufficientarianism combines three claims: a priority claim that we have non-instrumental reasons to prioritize benefits in certain ranges over benefits in other ranges; a continuum claim that at least two of those ranges are on one continuum; and a deficiency claim that the lower a range on a continuum, the more priority benefits in that range have. This characterization of sufficientarianism sheds new light on two long-standing philosophical (...) debates, namely about the distinctiveness of sufficientarianism as a distributive principle and about the common objections to sufficientarianism.

Despite the prominence of thresholds in theories of distributive justice, there is no general account of what sort of role is played by the idea of a threshold within such theories. This has allowed an ongoing lack of clarity and misunderstanding around views that employ thresholds. In this article, I develop an account of the concept of thresholds in distributive justice. I argue that this concept contains three elements, which threshold views deploy when ranking possible distributions. These elements are (i) (...) the level of the threshold, (ii) what constitutes the value of the threshold, and (iii) how benefits above and below the threshold must be allocated. I highlight three contributions that this particular account of thresholds makes: it clarifies the nature of the shift that occurs at the threshold; it resolves a common misunderstanding about headcount principles; and it shows how the arbitrariness objection can be met.

Most right-libertarians deny the permissibility of government redistribution, referring to the inviolability of private property rights. In a rare exception, Eric Mack offers a right-libertarian argument for luck sufficientarianism based on the catastrophe clause. In this view, people who find themselves in trouble through no fault of their own may violate someone else’s property rights in minor ways to save their own lives. But since a literal interpretation of this clause makes property rights too uncertain, Mack proposes a system of (...) redistribution that will protect people from dire circumstances. As it only applies to those who find themselves in poverty through no fault of their own, Mack’s argument rules out a basic income. However, one can combine Mack’s argument with basic income by arguing that responsibility-insensitive sufficientarianism is superior to luck sufficientarianism. First, luck sufficientarianism allows for the counterintuitive conclusion that people who have made mistakes in their lives do not deserve help from the rest of the community, even if they are engaged in some socially important activity. Second, luck sufficientarianism unduly interferes with people’s private lives to distinguish between deserving and undeserving recipients of social assistance, and inevitably excludes some deserving recipients from the pool of recipients. Third, a condition for holding people responsible for their choices is that they have agency. But maintaining agency requires the presence of some kind of material resources that would protect people from the fear and stress associated with poverty. Thus, responsibility-insensitive sufficientarianism is superior to luck sufficientarianism as an interpretation of the catastrophe clause. And within a libertarian framework, this requires introducing a basic income. First, a basic income technically guarantees everyone protection from extreme poverty and destitution. Second, a basic income guarantees everyone autonomy in how they manage their resources. Third, a basic income does not require means testing and is therefore responsibility-insensitive. Mack’s catastrophe clause therefore offers a right-libertarian argument for a basic income. (shrink)

: Fabian Wendt proposes combining libertarian foundations with a proviso that requires a just system of private property to ensure that everyone has a sufficient amount of resources to pursue projects. He calls this proviso a sufficiency proviso. This proviso is said to have advantages over all rival provisos “because it better coheres with the […].

Despite the prominence of thresholds and limits in theories of distributive justice, there is no general account of their role within such theories. This has allowed an ongoing lack of clarity and misunderstanding around threshold views in distributive justice. In this thesis, I develop an account of the conceptual structure of such views. Such an account helps understand and characterize threshold views, can subsume what may seem to be different debates about such views under one conceptual header, and can be (...) used to further examine and develop patterns of justice that draw on thresholds. In light of this account, I propose a novel characterization of sufficientarianism which sheds new light on the distinctiveness of sufficientarianism as a distributive principle and on the common objections to sufficientarianism. Moreover, I examine and defend limitarianism, which is the view that people should not have more than a certain amount of wealth. In particular, I argue in favour of limitarianism as a midlevel principle for guiding institutional design and individual actions and, furthermore, as a specification of what a just allocation of wealth requires under epistemic constraints.
