Liam Shields systematically clarifies and defends the political philosophy of Sufficientarianism, which insists that securing enough of some things, such as food, healthcare and education, is a crucial demand of justice. By engaging in practical debates about critical issues such as child-rearing and global justice, the author sheds light on the potential implications of suffientarianism on the social policies that affect our daily lives.

Logical frameworks that are sensitive to features of sentences’ subject-matter—like Berto’s topic-sensitive intentional modals (TSIMs)—demand a maximally faithful model of the topics of sentences. This is an especially difficult task in the case in which topics are assigned to intensional formulae. In two previous papers, a framework was developed whose model of intensional subject-matter could accommodate a wider range of intuitions about particular intensional conditionals. Although resolving a number of counterintuitive features, the work made an implicit assumption that the subject-matter (...) of an intensional conditional is a function of the subject-matters of its subformulae. This assumption—which I will call a principle of topic sufficiency—runs counter to some natural intuitions concerning topic. In this paper, we will investigate topic sufficiency and offer a semantic account that is state-sensitive, providing an implementation through the introduction of topic-sensitive logics related to William Parry’s prototypical $\mathsf {PAI}$.

A. G. Long presents a new account of the importance of conversation in Plato's philosophy.

According to a widely discussed view, knowledge plays a significant normative role in action: It is epistemically rational to treat p as your reason for action if and only if you know that p. As many philosophers have observed, however, this view clashes with the claim that knowledge is moderate and stable. For, granting that claim, there will be high stakes cases in which knowledge seems insufficient. To deal with such cases, some philosophers embracing the knowledge norm combine three independently (...) plausible claims. First, they say that no non-trivial condition is luminous; second, they say that doing something while not being in a position to know that that is appropriate is bad (in high stakes cases); third, they say that in the high stakes cases in question, the subject knows but fails to be in a position to know that she knows (Williamson Philos Q 55:213–235, 2005). This paper argues that this account can overcome the main objections already raised in the literature, but that it still faces the apparently insurmountable challenge of providing a natural and helpful way of substantiating the second claim.

Necessity and sufficiency are the building blocks of all successful explanations. Yet despite their importance, these notions have been conceptually underdeveloped and inconsistently applied in explainable artificial intelligence, a fast-growing research area that is so far lacking in firm theoretical foundations. In this article, an expanded version of a paper originally presented at the 37th Conference on Uncertainty in Artificial Intelligence, we attempt to fill this gap. Building on work in logic, probability, and causality, we establish the central role (...) of necessity and sufficiency in XAI, unifying seemingly disparate methods in a single formal framework. We propose a novel formulation of these concepts, and demonstrate its advantages over leading alternatives. We present a sound and complete algorithm for computing explanatory factors with respect to a given context and set of agentive preferences, allowing users to identify necessary and sufficient conditions for desired outcomes at minimal cost. Experiments on real and simulated data confirm our method’s competitive performance against state of the art XAI tools on a diverse array of tasks. (shrink)

A central project for the neuroscience of consciousness is to reveal the neural basis of consciousness. For the past 20-odd years, this project has been conceptualized in terms of minimal sufficiency. Recently, a number of authors have suggested that the project is better conceived in mechanistic terms as the search for difference-makers. In this paper, I (i) motivate this mechanistic alternative to minimal sufficiency, (ii) develop it further by clarifying debates about the prospects of leveraging mutual manipulability to (...) distinguish constitutive difference-makers from those that are merely causal, and (iii) explore the implications this has for recent debates concerning the status of the prefrontal cortex. I argue that adopting a mechanistic approach to the neuroscience of consciousness suggests that the prefrontal cortex is part of the neural mechanisms underlying consciousness even if it is not strictly speaking a necessary part.

Among the novel objects that attracted my attention during my stay in the United States, nothing struck me more forcibly than the general equality of condition among the people. (de Tocqueville 1990, 7)There are significant inequalities in the lives of America's children, including inequalities in the education that these children receive. These educational inequalities include not only disparities in funding per pupil but also in class size, teacher qualification, and resources such as books, labs, libraries, computers, and curriculum, as well (...) as the physical condition of the school and the safety of students within it. While not all schools attended by poor children are bad schools, and not all schools attended by well-off children are good schools, there are clear patterns. Poor children are more likely to attend crowded and poorly equipped schools with less qualified teachers than the children of more affluent families. They are less likely to have computers, books, and advanced placement academic courses. (Satz 2007, 623). (shrink)

In this chapter, the implications of intergenerational sufficientarianism for health-related issues are discussed. First, the chapter presents intergenerational sufficientarianism and specifies three of its key features: moderate noncleronomicity, a qualified authorization to save and dissave, and two characteristics of its metrics. It also discusses two specific defenses of sufficientarianism in the intergenerational realm. Second, the chapter applies the sufficientarian framework with an isolationist approach to three health-related issues: patent length, eradication versus control, and antibiotic resistance. Finally, it discusses whether isolationism (...) is more defensible in the case of intergenerational sufficientarianism than it could possibly be for other theories of justice. (shrink)

This chapter argues that standard accounts of health are ill-suited to constructing a plausible theory of health justice, particularly a sufficientarian theory. The problem in these accounts is revealed by their treatment of disability. Theorists of health justice need to define “health” more narrowly to capture the legitimate claims of people with disabilities. Following Ronald Amundson and Peter Hucklenbroich, this chapter proposes such a definition. Health, as defined in this chapter, is the absence of conditions that directly cause, or threaten (...) to directly cause, certain kinds of bodily harm, such as pain and premature death. It is concluded that on a plausible sufficientarian theory of health justice, a society that achieves health justice is one that ensures that none of its members face too much of those kinds of bodily harm.

This paper considers an allegation by M. Stocker and E. Hegeman that Aristotle’s account of anger yields a narcissistic passion bedevilled by illusions of self-sufficiency. The paper argues on behalf of Aristotle’s valuing of anger within a virtuous and flourishing life, showing that and why Aristotle’s account is neither narcissistic nor involves illusions of self-sufficiency. In so arguing a deeper appreciation of Aristotle’s understanding of a self-sufficient life is reached, as are some interesting contrasts between Aristotle's understanding of (...) anger, its connections to value and our own understanding of these matters.

The Consequence Argument for incompatibilism is beset by two rival interpretations: the counterfactual sufficiency interpretation and the counterfactual might interpretation. In a 2023 paper Waldrop argued that the counterfactual sufficiency interpretation conflicts with certain principles governing the logic of counterfactuals. In this paper, I show that Waldrop’s argument can be adapted to prove that the counterfactual might interpretation also conflicts with the same principles. So the problem Waldrop pointed out is not peculiar to the counterfactual sufficiency interpretation.

A common objection to sufficientarianism is that it allows large inequalities above the threshold. A sharpened form of this objection highlights that this indifference also encompasses large inequalities in the distribution of burdens. Consider the burdens that follow from climate change. A theory that does not rule out placing these burdens on the worst off (of the sufficiently well off) will appear implausible to many. This paper assesses ways of addressing this objection and defends a revised conception of sufficientarianism that (...) can demand fair distribution of burdens (and benefits) above the sufficiency threshold, without giving up core sufficientarian theoretical commitments.

This paper outlines a conceptual framework for a sufficiency economy, defining sufficiency as the space between a generalizable notion of human wellbeing and ungeneralisable excess. It assumes an objective and universal concept of human needs to define a ‘floor’ and the concept of planetary boundaries to define a ‘ceiling’. This is set up as an alternative to the dominant preference satisfaction theory of value. It begins with a brief survey of the potential contributions of sufficientarianism and limitarianism to (...) this endeavor before outlining a theory of objective, universal human need. This recognizes the contextual variable nature of need satisfiers and the distinct methodology required to adjudicate necessities. It then turns to the planetary boundaries literature and utilizes a sequence of causal and normative reasoning to derive an operational ceiling and the concept of ungeneralisable luxuries. The final section addresses how the concepts of floors and ceilings might be operationalized via forms of dialogic democracy but noting the absence of any such institutions at the global level. Its policy conclusion is that a safe climate cannot be achieved through supply-side mitigation alone, and that fair demand-side mitigation necessarily requires a clear distinction between necessities and unnecessary luxuries, between which (hopefully) lies a space of sufficiency.

One of the areas of concern raised by cross-border reproductive travel regards the treatment of women who are solicited to provide their ova or surrogacy services to foreign consumers. This is particularly troublesome in the context of developing countries where endemic poverty and low standards for both medical care and informed consent may place these women at risk of exploitation and harm. We explore two contrasting proposals for policy development regarding the industry, both of which seek to promote ethical outcomes (...) and social justice: While one proposal advocates efforts to minimize cross-border demand for female reproductive resources through the pursuit of national self-sufficiency, the other defends cross-border trade as a means for meeting the needs of vulnerable groups. Despite the conflicting objectives of the proposed strategies, the paper identifies common values and points of agreement between the two, including the importance of regulations to safeguard those providing ova or surrogacy services.

This chapter serves to provide an introduction to sufficientarianism. It first presents an overview of distinctions between sufficiency and other distributive pattern views—that is, utilitarianism, distributive egalitarianism, and the priority view. Second, it details six significant elements that need to be specified by a sufficiency theory—for example, the positive and positioning claims—as well as justifications for sufficiency principles. Last, it highlights a number of influential criticisms of sufficiency views, such as the indifference objection and the problem (...) of prioritizing the better off. The chapter provides the background for understanding how sufficiency principles need to be specified in theory as well as how they can be applied to health and health care, thus contextualizing the rest of the chapters in the volume.

Climate change is a threat to food system stability, with small islands particularly vulnerable to extreme weather events. In Puerto Rico, a diminished agricultural sector and resulting food import dependence have been implicated in reduced diet quality, rural impoverishment, and periodic food insecurity during natural disasters. In contrast, smallholder farmers in Puerto Rico serve as cultural emblems of self-sufficient food production, providing fresh foods to local communities in an informal economy and leveraging traditional knowledge systems to manage varying ecological and (...) climatic constraints. The current mixed methods study sought to document this expertise and employed a questionnaire and narrative interviewing in a purposeful sample of 30 smallholder farmers after Hurricane María to identify experiences in post-disaster food access and agricultural recovery and reveal underlying socioecological knowledge that may contribute to a more climate resilient food system in Puerto Rico. Although the hurricane resulted in significant damages, farmers contributed to post-disaster food access by sharing a variety of surviving fruits, vegetables, and root crops among community members. Practices such as crop diversification, seed banking, and soil conservation were identified as climate resilient farm management strategies, and smallholder farmer networks were discussed as a promising solution to amass resources and bolster agricultural productivity. These recommendations were shared in a narrative highlighting socioecological identity, self-sufficiency, community and cultural heritage, and collaborative agency as integral to agricultural resilience. Efforts to promote climate resilience in Puerto Rico must leverage smallholder farmers’ socioecological expertise to reclaim a more equitable, sustainable, and community-owned food system. (shrink)

At the beginning of his book Body, Community, Language, World, Jan Patočka claims that the human body has never been considered worthy of reflection throughout the entire (Western) philosophical tradition. Human corporeity has been largely excluded from philosophical reflections since the times of Plato’s conception of the human as a being divided between a mortal body and an immortal soul. Yet there is one thinker who had, as early as the nineteenth century, described the history of philosophy, from Plato to (...) Hegel, as a history of the loss of human corporeity. This philosopher was Ludwig Feuerbach. While Patočka follows the path of phenomenological anthropology, Feuerbach tries to return the sense of corporeity to the human being through the rehabilitation of sensuous perceptions and emotions. Despite their different approaches to the problem, Patočka and Feuerbach both agree with the notion that intersubjectivity, based on the corporeity of two autonomous subjects, stands outside of any cognitive pattern. They both persist in their efforts to bring the human body back into philosophy as a relevant source of experience because they both understand that the human body remains a universal symbol across all cultures and societies.

This chapter assesses the ethics of two-tiered health care systems according to two theories—a sufficiency of capabilities approach (CA) and social-relational egalitarianism. It is argued that a particular specification of a sufficiency of CA, based on Nussbaum’s CA and applied to health care justice, seems to provide a normative basis for the permissibility of certain kinds of two-tiered health care systems. A particular theory of equality, social egalitarianism, in contrast, can provide a convincing critique of these systems, and (...) this may seem to jeopardize the plausibility of the CA. This chapter argues, however, that the CA has the potential to accommodate social egalitarianism. For two-tiered systems, this means that they are likely to be deemed morally unacceptable when there are major discrepancies between the benefits or services made available in the first tier in comparison to the second tier and if parallel substitutive insurance systems are instituted.

It is well known that there are large differences in the per capita income levels of the world's states. While a few poor countries are catching up with the rich world, for some countries, the gaps are growing wider. Most of this global inequality isbetweencountries, notwithinthem. In other words, even if income were equalized within countries, a large part of the gap in average income levels between countries would remain.At the same time, the majority of movements in the wealthier countries (...) for greater distributive equality have tended to focus on inequalities within their own borders: on issues such as raising minimum wages, changing the domestic tax rate, and ending national health disparities. This state-centric focus is frequently justified in moral terms. It is a familiar claim, for example, that we have special obligations to our own citizens and that these obligations are both weightier and more extensive than our obligations to strangers outside our borders.

Neural correlates of consciousness (for brevity NCC) are foundational to the scientific study of consciousness. Chalmers (2000) has provided the most informative and influential definition of NCC, according to which neural correlates are minimally sufficient for consciousness. However, the sense of sufficiency needs further clarification since there are several relevant senses with different entailments. In section one of this article, we give an overview of the desiderata for a good definition of NCC and Chalmers’s definition. The second section analyses (...) the merit of understanding the sufficiency of neural correlates for corresponding consciousness according to three relevant types of sufficiency: logical, metaphysical, and physical. In section three, a theoretical approach to consciousness studies is suggested in light of the sense in which NCC are sufficient for consciousness. Section four addresses a concern some might have about this approach. By the end, it will become apparent that our conception of NCC has important implications for research methodology, neuroethics, and the vitality of the search for NCC. (shrink)

The idea of using responsibility in the allocation of healthcare resources has been criticized for, among other things, too readily abandoning people who are responsible for being very badly off. One response to this problem is that while responsibility can play a role in resource allocation, it cannot do so if it will leave those who are responsible below a “sufficiency” threshold. This paper considers first whether a view can be both distinctively sufficientarian and allow responsibility to play a (...) role even for those who will be left with very poor health. It then draws several further distinctions that may affect the application of responsibility at this level. We conclude that a more plausible version of the sufficientarian view is to allow a role for responsibility where failure to do so will leave someone else who is not responsible below the sufficiency threshold. However, we suggest that individuals must exhibit “sufficient responsibility” in order for this to apply, involving both a sufficient level of control and an avoidable failure to respond adequately to reasons for action.

A libertarian theory of justice holds that persons are self-owners and have the Hohfeldian moral power to justly acquire property rights in initially unowned external resources. Different variants of libertarianism can be distinguished according to their stance on the famous Lockean proviso. The proviso requires, in Locke’s words, to leave ‘enough and as good’ for others, and thus specifies limits on the acquisition of property. Left-libertarians accept an egalitarian interpretation of the proviso, ‘right-libertarians’ either reject any kind of proviso or (...) accept rather weak versions of it. In be-tween there is room for moderate interpretations of the proviso, and in particular for a sufficientarian interpretation: a ‘sufficiency proviso.’ The resulting theory of justice can be called ‘moderate libertarianism.’ In this article I make a case for moderate libertarianism, so understood. I argue that moderate libertarianism has advantages over both left- and right-libertarianism because it better coheres with the most plausible rationale for endorsing a libertarian theory of justice in the first place.

In this essay, I read Stuart Hall’s idea of “politics without guarantees” as meaning that all concepts are saturated with history and that no use of a concept can prevent it from being co-opted. The contribution of this reading is that it shifts the task of critical theory: if all concepts carry limitations and can be used to advance domination, then critical theorists need not search for pure concepts or worry about how to prevent our concepts from being captured. Instead, (...) our task is to strategically leverage always already imperfect concepts with a view toward shared political goals. For an example of this kind of critical theory, I look to W. E. B. Du Bois’s uses of “human,” “humanity,” and “human rights” in Black Reconstruction, which I suggest were informed by how he came to understand “humanity” in John Brown. (shrink)

This article analyses the concept of sufficiency in relation to sustainability and discusses ethical implications for sustainable organisation in time and place. We identify three foundational conceptualisations of sufficiency related to sustainability: (1) a limits model that starts with objective boundaries imposed by the biosphere and basic human needs; (2) a preference model that treats sufficiency as a subjective inclination for moderation defined situationally; and (3) a balancing model that seeks to integrate the objective limits and subjective (...) preferences by focussing on action embedded in the socio-ecological context. This includes balancing the needs of humans with those of non-humans. The limits model builds on universal duty, the preference model on preference utilitarianism and the balancing model on action-oriented virtue ethics. The balancing model of sufficiency is well suited to meeting the needs of present and future generations as well as delivering intra- and inter-generational justice not limited to humans. (shrink)

We study a logic for deontic necessity and sufficiency, as originally proposed in van Benthem :36–41, 1979). Building on earlier work in modal logic, we provide a sound and complete axiomatization for it, consider some standard extensions, and study other important properties. After that, we compare this logic to the logic of “obligation as weakest permission” from Anglberger et al. :807–827, 2015).

G. A. Cohen conceptualizes socialism as luck egalitarianism constrained by a community principle. The latter mitigates certain inequalities to achieve a shared common life. This article explores the plausibility of the community constraint on inequality in light of two related problems. First, if it is voluntary, it fails as a response to “the abandonment objection” to luck egalitarianism, as it would not guarantee imprudent people sufficient resources to avoid deprivation and to function as equal citizens in a democratic society. Contra (...) Cohenite socialism, this appears unjust. Second, if it is instead enforced, coercive equalization beyond sufficiency-constrained luck egalitarianism, which is possibly necessary to achieve a shared common life, seems to require unjustified restrictions on liberty. I therefore argue that the constraint is most plausibly specified as requiring enforcement of sufficiency and only voluntary equalization thereafter. I also note, skeptically, why this constraint might be morally preferable to a purely sufficientarian alternative. (shrink)
