Luck egalitarianism is a family of egalitarian theories of distributive justice that aim to counteract the distributive effects of luck. This article explains luck egalitarianism's main ideas, and the debates that have accompanied its rise to prominence. There are two main parts to the discussion. The first part sets out three key moves in the influential early statements of Dworkin, Arneson, and Cohen: the brute luck/option luck distinction, the specification of brute luck in everyday or theoretical terms and the specification (...) of advantage as resources, welfare, or some combination of these. The second part covers three later developments: the democratic egalitarian critique of luck egalitarianism, the luck egalitarian acceptance of pluralism, and luck egalitarian doubts about the significance of the brute luck/option luck distinction.

This paper focuses on the research field of machine ethics and how it relates to a technological singularity—a hypothesized, futuristic event where artificial machines will have greater-than-human-level intelligence. One problem related to the singularity centers on the issue of whether human values and norms would survive such an event. To somehow ensure this, a number of artificial intelligence researchers have opted to focus on the development of artificial moral agents, which refers to machines capable of moral reasoning, judgment, and decision-making. (...) To date, different frameworks on how to arrive at these agents have been put forward. However, there seems to be no hard consensus as to which framework would likely yield a positive result. With the body of work that they have contributed in the study of moral agency, philosophers may contribute to the growing literature on artificial moral agency. While doing so, they could also think about how the said concept could affect other important philosophical concepts. (shrink)

In this article I review Jonathan Wolff and Avner de‐Shalit’s recent book Disadvantage (2007), highlighting its many contributions to egalitarian theory and practice. These contributions build to the authors’ central prescription: that policy‐makers work to create a society of equals by reducing the tendency for disadvantages to cluster around certain individuals or groups. From there, I discuss the idea of declustering disadvantage in an American context, and consider its implications for the politically salient ideal of equality of opportunity. The purpose (...) of this discussion is not to posit Wolff and de‐Shalit’s theory of disadvantage as a theory of justice as equal opportunity. Instead, I illustrate their approach by reference to an influential theory of justice, whose proponents include those taken to affirm the authors’ consensual starting point. (shrink)

Traditional outcome-orientated egalitarian principles require access to information about the size of individual holdings. Recent egalitarian political theory has sought to accommodate considerations of responsibility. Such a move may seem problematic, in that a new informational burden is thereby introduced, with no apparent decrease in the existing burden. This article uses a simple model with simulated data to examine the extent to which outcome egalitarianism and responsibility-sensitive egalitarianism (‘luck egalitarianism’) can be accurately applied where information is incomplete or erroneous. It (...) is found that, while outcome egalitarianism tends to be more accurately applied, its advantage is not overwhelming, and in many prima facie plausible circumstances luck egalitarianism would be more accurately applied. This suggests that luck egalitarianism cannot be rejected as utopian. Furthermore, while some argue that, in practice, luck egalitarianism is best realized indirectly, by securing equality of outcome, our evidence suggests that a luck egalitarian rule of regulation offers a far more accurate implementation of the luck egalitarian ideal than does an outcome egalitarian rule of regulation.

Oppression can be unjust from a luck egalitarian point of view even when it is the consequence of choices for which it is reasonable to hold persons responsible. This is for two reasons. First, people who have not been oppressed are unlikely to anticipate the ways in which their choices may lead them into oppressive conditions. Facts about systematic phenomena (like oppression) are often beyond the epistemic reach of persons who are not currently subject to such conditions, even when they (...) possess adequate information about the particular consequences of their choices. Second, people may be (much) less responsible for remaining in oppressive conditions, even if they are responsible for entering circumstances of oppression. Oppression that results from a person’s choice may cause or contribute to dramatic changes in that person, and these changes may be sufficient to undermine the person’s responsibility for the results of her earlier choice.

In this article, we provide an ethical analysis of the first porcine cardiac xenotransplant, performed in Maryland, USA in early 2022. David Bennett was offered the experimental procedure after he was deemed ineligible for human heart transplantation and mechanical circulatory support, based on a history of non-compliance. It was reported that Mr Bennett’s previous instances of non-compliance were for medically non-life-threatening conditions years earlier, where the risks of non-compliance were not as high. We argue that, in Mr Bennett’s case, a (...) history of non-compliance in a different context, should not necessarily rule him ineligible for a potentially life-saving treatment now. Furthermore, using previous non-compliance to exclude individuals from donor organs may have the unintended effect of placing the burden of testing xenotransplantation on those who are already disadvantaged. We then argue that it is not enough to rely on patient consent to ethically justify xenotransplantation research. Taking a broad ethical perspective is crucial when mapping a clinical pathway for xenotransplantation. (shrink)

A considerable literature has emerged around the idea of using ‘personal responsibility’ as an allocation criterion in healthcare distribution, where a person's being suitably responsible for their health needs may justify additional conditions on receiving healthcare, and perhaps even limiting access entirely, sometimes known as ‘responsibilisation’. This discussion focuses most prominently, but not exclusively, on ‘luck egalitarianism’, the view that deviations from equality are justified only by suitably free choices. A superficially separate issue in distributive justice concerns the two–way relationship (...) between health and other social goods: deficits in health typically undermine one's abilities to secure advantage in other areas, which in turn often have further negative effects on health. This paper outlines the degree to which this latter relationship between health and other social goods exacerbates an existing problem for proponents of responsibilisation (the ‘harshness objection’) in ways that standard responses to this objection cannot address. Placing significant conditions on healthcare access because of a person's prior responsibility risks trapping them in, or worsening, negative cycles where poor health and associated lack of opportunity reinforce one another, making further poor yet ultimately responsible choices more likely. It ends by considering three possible solutions to this problem. (shrink)

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.

Luck egalitarianism has been criticized for condoning some cases of oppression and condemning others for the wrong reason—namely, that the victims were not responsible for their oppression. Oppression is unjust, however, the criticism says, regardless of whether victims are responsible for it, simply because it is contrary to the equal moral standing of persons. I argue that four luck egalitarian responses to this critique are inadequate. Two address only the first part of the objection and do so in a way (...) that risks making luck egalitarianism inconsistent. A third severely dilutes the luck egalitarian doctrine. A fourth manages to denounce some instances of oppression for the right reason, but at the same time permits other instances of oppression and condemns yet others for the wrong reason. (shrink)

Las consecuencias de la pandemia pueden considerarse como desgracias o injusticias. En este escrito mostraré que la situación general en Chile se configura como una injusticia. Para justificar el punto anterior describiré a grandes rasgos las caracterı́sticas fundamentales del igualitarismo de la suerte. Luego, al exponer los datos disponibles en Chile, mostraré por qué en Chile las consecuencias del coronavirus se configuran como injusticias. En particular, mostraré que si los seres humanos son libres e iguales en derechos, entonces es necesario (...) que esa igualdad se exprese en su igual capacidad de enfrentar la suerte bruta. Ası́, los seres humanos son por una parte, libres, y por ende responsables, y por otro, iguales, y por ende, libres de la suerte bruta. Por lo tanto, el rol del estado, en tanto conjunto de instituciones que distribuyen justicia, es minimizar la suerte (bruta). La relación entre los efectos de la pandemia y condición socioeconómica debe leerse como el abandono de los ciudadanos a su suerte bruta. Dejar a los ciudadanos a su suerte no es simplemente una desgracia, es una injusticia. (shrink)

According to luck egalitarianism, it is unjust if some are worse off than others through no fault or choice of their own. The most common criticism of luck egalitarianism is the ‘harshness objection’, which states that luck egalitarianism allows for too harsh consequences, as it fails to provide justification for why those responsible for their bad fate can be entitled to society's assistance. It has largely gone unnoticed that the harshness objection is open to a number of very different interpretations. (...) We present four different interpretations of the harshness objection in which the problem pertains to counterintuitive implications, badness of outcome, disproportionality, or inconsistency, respectively. We analyse and discuss appropriate luck egalitarian replies. Disentangling these different versions clarifies what is at the heart of this dispute and reveals the point of the harshness objection. We conclude that only the inconsistency version involves a durable problem for luck egalitarianism. (shrink)

Can compensation repair the moral harm of a previous wrongful act? On the one hand, some define the very function of compensation as one of restoring the moral balance. On the other hand, the dominant view on compensation is that it is insufficient to fully repair moral harm unless accompanied by an act of punishment or apology. In this paper, I seek to investigate the maximal potential of compensation. Central to my argument is a distinction between apologetic compensation and non-apologetic (...) compensation. Apologetic compensation, I argue, is an act that expresses regret and apology by means of some offer of money, goods, or services. Non-apologetic compensation is an act that seeks to restore loss or harm without expressing regret or apology. In the paper, I defend the view that acts of compensation can be apologetic and argue that such apologetic compensation is sufficient for moral repair. (shrink)

Many philosophers believe that luck egalitarianism captures “desert-like” intuitions about justice. Some even think that luck egalitariansm distributes goods in accordance with desert. In this paper, we argue that this is wrong. Desertism conflicts with luck egalitarianism in three important contexts, and, in these contexts, desertism renders the proper moral judgment. First, compared to desertism, luck egalitarianism is sometimes too stingy: it fails to justly compensate people for their socially valuable contributions—when those contributions arose from “option luck”. Second, luck egalitarianism (...) is sometimes too restrictive: it fails to justly compensate people who make a social contribution when that contribution arose from “brute luck”. Third, luck egalitarianism is too limited in scope: it cannot diagnose economic injustice arising independently of comparative levels of justice. The lesson of this paper is that luck egalitarians should consider supplementing their theory with desert considerations. Or, even better, consider desertism as a superior alternative to their theory. (shrink)

In this paper I analyze a view that is increasingly spreading among philosophers and even physicians. Many of them believe that it is right to apply the principle of responsibility for illness in the allocation of health care. I attempt to show that this idea is unacceptable.

G.A. Cohen is famous for his critique of John Rawls’s view that principles of justice are restricted in scope to institutional structures. In recent work, however, Cohen has suggested that Rawlsians get more than just the scope of justice wrong: they get the concept wrong too. He claims that justice is a fundamental value, i.e. a moral input in our deliberations about the content of action-guiding regulatory principles, rather than the output. I argue here that Cohen’s arguments for extending the (...) scope of justice equivocate across his distinction between fundamental principles of justice, i.e. principles that tell us what justice is; and regulatory principles of justice, i.e. principles that tell us what is required of us, all things – including justice – considered. Though Cohen initially had the regulatory sense of the word ‘justice’ in mind when critiquing the basic structure restriction, his replies to the problem of demandingness presuppose his own, fundamental sense of the word ‘justice’. The upshot is that he escapes demandingness at the cost of sacrificing regulatory justice’s capacity to provide clear guidance. I conclude by considering Peter Singer’s efforts to deal with demandingness in his own work on global poverty. Since Singer manages to deal with demandingness without giving up clarity, his work is a good a place to start in the search for regulatory principles that are suitable for the context of personal choice.

Like American politics, the academic debate over justice is polarized, with almost all theories of justice falling within one of two traditions: egalitarianism and libertarianism. This book provides an alternative to the partisan standoff by focusing not on equality or liberty, but on the idea that we should give people the things that they deserve. Mulligan argues that a just society is a meritocracy, in which equal opportunity prevails and social goods are distributed strictly on the basis of merit. That (...) gives citizens their just deserts. In addition to its novel conceptual approach, meritocracy is distinctive from existing work in two ways. First, it is grounded in research on how people actually think about justice. Empirical research reveals that people don't think that social goods should be distributed equally. Nor do they dismiss the idea of social justice. Across ideological and cultural lines, people want rewards to reflect merit. Second, the book discusses hot-button political issues and makes concrete policy recommendations. These issues include anti-meritocratic bias against women and racial minorities and the United States’ widening economic inequality. Justice and the Meritocratic State offers a new theory of justice and provides solutions to our most vexing social and economic problems. It will be of keen interest to philosophers, economists, and political theorists. (shrink)

Este artículo mostrará que las versiones estrictas del Igualitarismo Democrático y del Igualitarismo de la Suerte son implausibles ya que defienden una visión monista del objeto de la justicia igualitaria. Por el contrario, sus versiones moderadas son aceptables ya que admiten la composición plural del objeto de justicia igualitaria. Esta comprensión plural exige, sin embargo, el establecimiento de prioridades normativas ya que las exigencias de cada valor entran típicamente en conflicto. Aquí, se ofrecerán tres argumentos para defender la prioridad del (...) Igualitarismo Democrático sobre el Igualitarismo de la Suerte: uno instrumental, otro relacionado con el significado expresivo de las políticas públicas estatales y un último que justifica la división del trabajo moral igualitarista.

According to luck egalitarianism, inequalities are justified if and only if they arise from choices for which it is reasonable to hold agents responsible. This position has been criticised for its purported harshness in responding to the plight of individuals who, through their own choices, end up destitute. This paper aims to assess the Harshness Objection. I put forward a version of the objection that has been qualified to take into account some of the more subtle elements of the luck (...) egalitarian approach. Revising the objection in this way suggests that the Harshness Objection has been overstated by its proponents: because luck egalitarians are sensitive to the influence of unequal brute luck on individuals’ choices, it is unlikely that there will be any real world cases in which the luck egalitarian would not have to provide at least partial compensation. However, the Harshness Objection still poses problems for the luck egalitarian. First, it is not clear that partial compensation will be sufficient to avoid catastrophic outcomes. Second, the Harshness Objection raises a theoretical problem in that a consistent luck egalitarian will have to regard it as unjust if any assistance is provided to the victim of pure option luck, even if such assistance could be provided at no cost. I consider three strategies the luck egalitarian could pursue to accommodate these concerns and conclude that none of these strategies can be maintained without either violating basic luck egalitarian principles or infringing upon individual liberty.

Critics of luck egalitarianism have claimed that, far from providing a justification for the public insurance functions of a welfare state as its proponents claim, the view objectionably abandons those who are deemed responsible for their dire straits. This article considers seven arguments that can be made in response to this ‘abandonment objection’. Four of these arguments are found wanting, with a recurrent problem being their reliance on a dubious sufficientarian or quasi-sufficientarian commitment to provide a threshold of goods unconditionally. (...) Three arguments succeed, showing that luck egalitarians have good reasons for assisting ‘negligent victims’ on account of changes that may occur in an individual between the time of their choice and their subsequent disadvantage, bad option luck, and doubts about free will and responsibility. Luck egalitarianism is therefore shown to offer strong support for public insurance. (shrink)

Several attempts have been made to apply the choice-sensitive theory of distributive justice, luck egalitarianism, in the context of health and healthcare. This article presents a framework for this discussion by highlighting different normative decisions to be made in such an application, some of the objections to which luck egalitarians must provide answers and some of the practical implications associated with applying such an approach in the real world. It is argued that luck egalitarians should address distributions of health rather (...) than healthcare, endorse an integrationist theory that combines health concerns with general distributive concerns and be pluralist in their approach. It further suggests that choice-sensitive policies need not be the result of applying luck egalitarianism in this context. (shrink)

This paper argues that luck egalitarianism, especially in the guise of equality of opportunity for welfare, is in tension with the ideal of fair equality of opportunity in three ways. First, equal opportunity for welfare is compatible with a caste system in employment that is inconsistent with open competition for positions. Second, luck egalitarianism does not support hiring on the basis of qualifications. Third, amending luck egalitarianism to repair this problem requires abandoning fair access to qualifications. Insofar as luck egalitarianism (...) cannot support fair equality of opportunity, it cannot do justice to the claims of the disabled. Indeed, in the absence of fair equality of opportunity, disabled people are likely to be marginalized. (shrink)

Luck egalitarians maintain that inequalities are always unjust when they are due to luck, but are not always unjust when they are due to choices for which the parties are responsible. In this paper, I argue that the two halves of this formula do not fit neatly together, and that we arrive at one version of luck egalitarianism if we begin with the notion of luck and interpret responsible choice in terms of its absence, but a very different version if (...) we begin with the notion of responsible choice and interpret luck in terms of its absence. I argue, further, that the difference between the two versions is significant because many real-world inequalities fall precisely in the gap between them, and that attempts to adjudicate between them lead quickly to hard questions about the relation between equality and responsibility.

The issue of distributive justice receives substantial amount of attention in our society. On the one hand, we are sensitive to whether and the extent to which people are responsible for being worse off. On the other hand, we are mindful of society’s worst-off members. There has been a debate over luck egalitarianism, which relates to the former concern, and relational egalitarianism, which echoes the latter. By investigating the psychological processes of these two concerns, this paper examines the reliability of (...) the argument that Elizabeth Anderson, a renowned relational egalitarian, presents against luck egalitarianism and for relational egalitarianism. It also considers whether it is possible to support luck egalitarianism and relational egalitarianism simultaneously, using an online experiment. The results of the experiment show that, first, for ordinary people, the luck consideration is as important as the basic capabilities consideration. Second, while real people consider the degree of compensation through the factors of causality and responsibility, the lack of basic capabilities directs them to determine how much victims of bad luck should be compensated. This suggests that pluralist egalitarianism is on the right track. (shrink)

Social egalitarians hold that one fundamental requirement of the ideal of social equality is that people should stand in relations of non-domination to one another. In the light of this, they reject luck egalitarian principles of justice as incompatible with a society of equals, because the former violate the non-domination requirement. I call this the domination objection. In this paper I examine its force against Dworkinian resource egalitarianism. There are two reasons why equality of resources might be thought to be (...) vulnerable to it. First, Dworkin has been interpreted to maintain that as long as people’s preferences are authentic, people should be consequentially responsible for the choices that flow from such preferences. However, Dworkin’s view on when people’s choices should be considered to be authentic does not rule out that the latter are sometimes influenced by norms and processes that are the outcome of domination and oppression, and so holding people fully consequentially responsible for choices that are the outcome of such preferences is itself unjust. Second, equality of resources objectionably permits bad-option-luck victims to become vulnerable to domination. I argue that Dworkinian egalitarianism is not susceptible to either of the two parts of the domination objection and defend the view that it is—contrary to the social egalitarian criticism—faithful to the social egalitarian demand for non-domination.

Debates over egalitarianism for the most part are not concerned with constraints on achieving an egalitarian society, beyond discussions of the deficiencies of egalitarian theory itself. This paper looks beyond objections to egalitarianism as such and investigates the relevant psychological processes motivating people to resist various aspects of egalitarianism. I argue for two theses, one normative and one descriptive. The normative thesis holds that egalitarians must take psychological constraints into account when constructing egalitarian ideals. I draw from non-ideal theories in (...) political philosophy, which aim to construct moral goals with current social and political constraints in mind, to argue that human psychology must be part of a non-ideal theory of egalitarianism. The descriptive thesis holds that the most fundamental psychological challenge to egalitarian ideals comes from what are called Just World Beliefs. A troubling result of Just World Beliefs, one that poses a prima facie obstacle to egalitarianism, is that people tend to dismiss or explain away any threats to their belief that the world is fundamentally just. The pervasiveness and severity of Just World Beliefs predicts that people will be resistant to egalitarian policies. My aim is to show how research on Just World Beliefs can help diagnose common problems for egalitarianism and assist in making realistic recommendations for bringing current societies closer to egalitarian ideals.

A recurring concern about luck egalitarianism is that its implementation would make some individuals, in particular those who lack marketable talents, experience shame. This, the objection goes, undermines individuals’ self-respect, which, in turn, may also lead to unequal respect between individuals. Loss of (self-)respect is a concern for any egalitarian, including distributive egalitarians, inasmuch as it is non-compensable. This paper responds to this concern by clarifying the relationship between shame and (self-)respect. We argue, first, a luck egalitarian society and ethos (...) would be radically different from the current one and incompatible with shame over lack of talent, and, second, that while shame may still occur in a less than ideal luck egalitarian society, this kind of shame does not undermine egalitarian commitments.

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.

:Influenced by the people-centered integrated care model, Healthy China 2030 was drafted recently with a special concern given to patient engagement. Although there are three levels of engagement, patients are more likely to be empowered and activated through an individualistic approach. Thus, engaging patients at the household level appear to have been overlooked so far. Supported by ethical values and practical evidence, this article attempts to address the importance of engaging patients at the household level in shaping the Chinese healthcare (...) system with the PCIC model orientation, and thus recommends four strategies for empowering and activating patients at the household level in the Chinese context.

Is equality a distributive value or does it rather point to the quality of social relationships? This article criticizes the distributive character of luck egalitarian theories of justice and fleshes out the central characteristics of an alternative, relational approach to equality. It examines a central objection to distributive theories: that such theories cannot account for the significance of how institutions treat people (as opposed to the outcomes they bring about). I discuss two variants of this objection: first, that distributive theories (...) fail to account for the importance of how institutions cause good shortfalls and, second, that they fail to account for the normative attitude of social and political institutions expressed in different ways of treating people. The article argues that the causal variant of the objection has only very limited reach, and endorses the expressive variant: the attitudes expressed by institutions in their treatment of persons, such as contempt or neglect, generate potentially unjust social relationships and hierarchies. This should be the focus of a relational egalitarian approach to social justice. The article proceeds to explain how it is possible that artificial agents such as institutions have attitudes and how these attitudes are not reducible to those of the individuals that sustain them, and argues that distributive theories cannot be so modified as to account for such attitudes. It concludes by indicating several directions for the development of more worked-out conceptions of relational equality on this basis. (shrink)

It has been common for researchers and commentators within the discipline of Social and Public Policy to evoke Rawlsian theories of justice. Yet some now argue that the contractualist tradition cannot adequately incorporate, or account for, relations of care, respect and interdependency. Though contractualism has its flaws this article proposes that we should not reject it. Through a critique of one of its most esteemed critics, Martha Nussbaum, it proposes that contractualism can be defended against the capabilities approach she prefers. (...) The article concludes by suggesting how and why the moral philosophy of Thomas Scanlon offers a basis for reconciling the strengths of a contractualist, egalitarian liberalism with those of Nussbaum’s capabilities approach. (shrink)

Over many years, different theories have been developed to guide the social practices and policies of institutions so that they demonstrate equal concern and respect for all, and satisfy the requirements of justice. Although the normative principles described in a theory may support just institutions, whether this results in just outcomes will depend on how the decisions that implement the principles are made and actioned. As a societal institution charged with caring for people, ensuring just outcomes is a distinct concern (...) in healthcare. Relationships within this institution are constitutive of human flourishing and are also important to justice. Yet, it is not possible to create, maintain or evaluate interpersonal relationships in the same manner as institutions because rather than being universal and impartial, they are particular and partial. Consequently, the link between theories of justice that guide decision-making in relation to structures or institutions, and the relationships that influence those with a proximate effect on individuals, is not explicit. To address this gap, this article argues that a focus on human flourishing provides a nexus between the decision-making for just institutions and just outcomes for individuals. (shrink)

The Intergovernmental Panel for Climate Change has over the past decade repeatedly warned that we are heading towards inevitable and irreversible climate change, which will negatively affect the lives, livelihoods, and well-being of millions of people around the world, both at present and in the future. In fact, many people, especially vulnerable and marginalized communities in low- and middle-income countries, already live with the effects of climate change in their daily lives. While adaptation – along with mitigation and compensation for (...) loss and damage as a consequence of climate change – was identified as the central pillars of a just climate policy in the Paris Agreement it is unclear whether this entails a right to adaptation – that some people are owed, as a matter of justice, to have the ability to adapt to climate change – and, if so, what such a right would look like. In this paper, I argue that individuals and communities who are or will be negatively affected by climate change through no fault of their own should have the right to adaptation. I argue that the right to adaptation should be specified through four questions: (i) who has a right to adaptation; (ii) what is it a right to; (iii) how much is it a right to; and (iv) who has the duty to uphold the right to adaptation?
