In this paper I address the objection to sufficientarianism posed by Paula Casal and Richard Arneson, that it is hard to conceive of a sufficiency threshold such that distribution is highly important just below it, and not required at all just above it. In order to address this objection, I elaborate on the idea that sufficientarianism structurally can be seen to require two separate thresholds, which may or may not overlap. I then argue that a version of such a (...) view is plausible. Lastly, I distinguish this view from related proposals in the literature. (shrink)

Past appraisal studies have shown that single appraisals are neither sufficient nor necessary for emotions but no study has examined the same issue with appraisal configurations (combinations of different single appraisals). Undergraduate participants repeatedly indicated their negative emotions (anger, sadness, fear, and guilt) and relevant appraisals as they occurred, or immediately after, in their everyday environments. The results not only replicated past findings on single appraisals but also suggested that appraisal configurations are neither sufficient nor necessary for these negative emotions.

Telic sufficientarianism is the view that it is better, other things equal, if people are lifted above some sufficiency threshold of special moral importance. In a recent contribution, Shlomi Segall has raised the following objection to this position: The telic ideal of sufficiency can neither be grounded on any personal value, nor any impersonal value. Consequently, sufficientarianism is groundless. This article contains a rejoinder to this critique. Its main claim is that the value of autonomy holds strong potential (...) for grounding sufficiency. It argues, firstly, that autonomy carries both personal value for its recipient as well as impersonal value, and that both of these values are suitable for grounding sufficiency. It thus follows that we should reject both and. Secondly, although autonomy is presumably the strongest candidate for grounding sufficiency, the article provides some counterargument to Segall's rejection of the other candidates — the impersonal value of virtue; the personal value for the allocator; and the personal value for others. If the arguments are sound, they show that we need not worry about sufficientarianism being groundless. (shrink)

This essay examines the management of ventilatory failure in disaster settings where clinical needs overwhelm available resources. An ethically defensible approach in such settings will adopt a “sufficiency of care” perspective that is: (1) adaptive, (2) resource-driven, and (3) responsive to the values of populations being served. Detailed, generic, antecedently written guidelines for “ventilator triage” or other management issues typically are of limited value, and may even impede ethical disaster response if they result in rescuers’ clumsily interpreting events through (...) the lens of the guideline, rather than customizing tactics to the actual context. Especially concerning is the tendency of some expert planners to mistakenly assume that medical treatment of respiratory failure: (1) always requires full-feature mechanical ventilators, (2) will always occur in hospitals, and (3) can be planned in advance without sophisticated public consultation about likely ethical dilemmas.

Sufficient conditions for first-order-based sequent calculi to admit cut elimination by a Schütte–Tait style cut elimination proof are established. The worst case complexity of the cut elimination is analysed. The obtained upper bound is parameterized by a quantity related to the calculus. The conditions are general enough to be satisfied by a wide class of sequent calculi encompassing, among others, some sequent calculi presentations for the first order and the propositional versions of classical and intuitionistic logic, classical and intuitionistic modal (...) logic S4, and classical and intuitionistic linear logic and some of its fragments. Moreover the conditions are such that there is an algorithm for checking if they are satisfied by a sequent calculus. (shrink)

The traditional conception of human rights, or the orthodox conception (OC), has, over the last few years, been vigorously challenged by the political conception (PC) of human rights. I have two main aims in this paper: the first is to articulate and evaluate the main points of disagreement between the OC and the PC in order to provide a clearer picture of what is at stake in the debate. The second is to argue that the OC has the resources to (...) respond to the PC's most challenging criticism; namely that it is not sufficiently political. (shrink)

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.

My aim is to show that supervenience claims follow from instances of a principle I call the principle of defeasibly sufficient reason. This principle construes the completeness of physics quite differently from strong or reductive physicalism and encodes both scientific and common sense patterns of explanation and justification. Rather than thoroughly defending the principle in the short space of this paper, I will sketch how one might defend it and a resulting fainthearted physicalism.

In recent decades political philosophers have increasingly been engaged with the issue of educational equality. However, egalitarians typically focus on achieving equality in the distribution of education, and ignore the relevance of an alternative, relational conception of equality. An exception to this is Elizabeth Anderson, who applies relational egalitarian principles to education in her 2007 article ‘Fair Opportunity in Education: A Democratic Equality Perspective’. Although Anderson remains one of the few relational egalitarians to consider what this ideal requires in education, (...) her arguments have received less attention than they deserve. In this article I examine Anderson's theory of fair educational opportunities for a democratic society of equals and develop an internal critique of her approach. I suggest that the sufficientarian standard Anderson proposes for education has the propensity to undermine the process of integration and the relations of equality she aspires to. Even if all children receive a sufficient education, inequality above the threshold could result in social divisions and status differentials that encourage informal segregation because people typically prefer to associate with other people who are similar to themselves. The article will finish by considering what implications this has for Anderson's relational egalitarian approach to education. (shrink)

The notion of sufficiency has recently gained some momentum in separate discourses on distributive justice (‘sufficientarianism') and the environment (‘eco-sufficiency'). An investigation of their relationship is warranted, as their scope overlaps in areas such as environmental justice and socio-economic policy. This paper argues that the two understandings of sufficiency are incompatible, because eco-sufficiency has adopted an extremely perfectionist view of the good life while sufficientarianism is committed to pluralism. A plausible explanation for this incompatibility relates to (...) the two different meanings of the term sufficiency as a limit (eco-sufficiency) and as a minimum requirement (sufficientarianism).

On relational structures and on polymodal logics, we describe operations which preserve local tabularity. This provides new sufficient semantic and axiomatic conditions for local tabularity of a modal logic. The main results are the following. We show that local tabularity does not depend on reflexivity. Namely, given a class $\mathcal {F}$ of frames, consider the class $\mathcal {F}^{\mathrm {r}}$ of frames, where the reflexive closure operation was applied to each relation in every frame in $\mathcal {F}$. We show that if (...) the logic of $\mathcal {F}^{\mathrm {r}}$ is locally tabular, then the logic of $\mathcal {F}$ is locally tabular as well. Then we consider the operation of sum on Kripke frames, where a family of frames-summands is indexed by elements of another frame. We show that if both the logic of indices and the logic of summands are locally tabular, then the logic of corresponding sums is also locally tabular. Finally, using the previous theorem, we describe an operation on logics that preserves local tabularity: we provide a set of formulas such that the extension of the fusion of two canonical locally tabular logics with these formulas is locally tabular.

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.

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.

Sufficiency principles generally state that it is especially important for justice that people have enough of certain goods, but it can be hard to give a convincing answer as to what level of goods counts as enough. This paper examines a recent sufficiency view by George Sher, who argues that the threshold level of resources and opportunities that the state should provide for each citizen is whatever level gives one enough leverage to obtain further resources and opportunities without (...) inordinate difficulty or sacrifice. The argument relies on the idea that, with regard to resources and opportunities, the sufficient ability to live one’s life effectively requires only that one have enough of them as leverage. While Sher’s general account regarding “what counts as enough?” is promising in countering certain challenges typically raised against sufficiency principles, the approach to determine the threshold of resources and opportunities in terms of leverage is problematic.

A Partial Combinatory Algebra is completable if it can be extended to a total one. In [1] it is asked (question 11, posed by D. Scott, H. Barendregt, and G. Mitschke) if every PCA can be completed. A negative answer to this question was given by Klop in [12, 11]; moreover he provided a sufficient condition for completability of a PCA (M, ·, K, S) in the form of ten axioms (inequalities) on terms of M. We prove that just one (...) of these axiom (the so called Barendregt's axiom) is sufficient to guarantee (a slightly weaker notion of) completability. (shrink)

Pearl opened the door to formally defining actual causation using causal models. His approach rests on two strategies: first, capturing the widespread intuition that X = x causes Y = y iff X = x is a Necessary Element of a Sufficient Set for Y = y, and second, showing that his definition gives intuitive answers on a wide set of problem cases. This inspired dozens of variations of his definition of actual causation, the most prominent of which are due (...) to Halpern & Pearl. Yet all of them ignore Pearl’s first strategy, and the second strategy taken by itself is unable to deliver a consensus. This paper offers a way out by going back to the first strategy: it offers six formal definitions of causal sufficiency and two interpretations of necessity. Combining the two gives twelve new definitions of actual causation. Several interesting results about these definitions and their relation to the various Halpern & Pearl definitions are presented. Afterwards the second strategy is evaluated as well. In order to maximize neutrality, the paper relies mostly on the examples and intuitions of Halpern & Pearl. One definition comes out as being superior to all others, and is therefore suggested as a new definition of actual causation. (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)

According to the sufficiency theory of justice in health, justice requires that people have equal access to adequate health. In this article, I lay out the structure of this view and I assess its distributive implications for setting priority (i) between health needs across persons and (ii) between health care spending and other societal goods. I argue, first, that according to the sufficiency theory, deficiency in health cannot be completely offset by providing other societal goods. And, second, that (...) it can prevent the medicalization of societies by stressing that improvements beyond the level of adequate health have relatively little weight, if any, from the standpoint of justice.

The Principle of Sufficient Reason says that all contingent facts must have explanation. In this 2006 volume, which was the first on the topic in the English language in nearly half a century, Alexander Pruss examines the substantive philosophical issues raised by the Principle Reason. Discussing various forms of the PSR and selected historical episodes, from Parmenides, Leibnez, and Hume, Pruss defends the claim that every true contingent proposition must have an explanation against major objections, including Hume's imaginability argument and (...) Peter van Inwagen's argument that the PSR entails modal fatalism. Pruss also provides a number of positive arguments for the PSR, based on considerations as different as the metaphysics of existence, counterfactuals and modality, negative explanations, and the everyday applicability of the PSR. Moreover, Pruss shows how the PSR would advance the discussion in a number of disparate fields, including meta-ethics and the philosophy of mathematics. (shrink)

In the standard analysis of economic institutions--which include social conventions, the working rules of an economy, and entitlement regimes --economists invoke the same theories they use when analyzing individual behavior. In this profoundly innovative book, Daniel Bromley challenges these theories, arguing instead for "volitional pragmatism" as a plausible way of thinking about the evolution of economic institutions. Economies are always in the process of becoming. Here is a theory of how they become. Bromley argues that standard economic accounts see institutions (...) as mere constraints on otherwise autonomous individual action. Some approaches to institutional economics--particularly the "new" institutional economics--suggest that economic institutions emerge spontaneously from the voluntary interaction of economic agents as they go about pursuing their best advantage. He suggests that this approach misses the central fact that economic institutions are the explicit and intended result of authoritative agents--legislators, judges, administrative officers, heads of states, village leaders--who volitionally decide upon working rules and entitlement regimes whose very purpose is to induce behaviors that constitute the sufficient reasons for the institutional arrangements they create. Bromley's approach avoids the prescriptive consequentialism of contemporary economics and asks, instead, that we see these emergent and evolving institutions as the reasons for the individual and aggregate behavior their very adoption anticipates. These hoped-for outcomes comprise sufficient reasons for new laws, judicial decrees, and administrative rulings, which then become instrumental to the realization of desired individual behaviors and thus aggregate outcomes.

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)

This article identifies value‐satiability sufficientarianism as a distinctive version of the sufficiency view, which has been ignored in the literature on distributive justice. This is unfortunate because value‐satiability sufficientarianism is much better equipped than alternative sufficiency views to cope with the standard objections against sufficiency. Most often, sufficientarianism refers to satiability as a feature of moral principles and reasons. But value‐satiability sufficientarianism also invokes satiability in the space of value‐theory, as it determines the sufficiency threshold at (...) the point where justice‐relevant values have been completely fulfilled. The article gives examples of how this view is widely apparent in the literature, and it provides some reasons in its favour. It then presents the two standard objections against sufficientarianism – the threshold objection and the indifference objection – and argues that these critiques do not apply to value‐satiability sufficientarianism. The general argument of the article therefore proves sufficientarianism more difficult to refute than is commonly credited. (shrink)

Kant’s theory of citizenship replaces the French revolutionary triptych of liberty, equality and fraternity with freedom (Freiheit), equality (Gleichheit) and civil self-sufficiency (Selbständigkeit). The interpretative question is what the third attribute adds to the first two: what does self-sufficiency add to free consent by juridical equals? This article argues that Selbständigkeit adds the idea of interdependent independence: the independent possession and use of citizens’ interdependent rightful powers. Kant thinks of the modern state as an organism whose members are (...) agents possessed of rightful (productive) powers, whose interdependent mode of exercise independently of unilateral permission matters for right. The empirical form of that ideal, according to Kant, is a republic of independent commodity producers. I will show that this reading of Selbständigkeit can consistently explain Kant’s disenfranchisement of women, wage labourers and landless farmers; that it offers a robust alternative to influential republican, libertarian and proprietarian interpretations of the Kantian state; and that it can buttress an original account of community as productive interdependence.

Leibniz' Prinzip des zureichenden Grundes soll hier aufgrund von Russells Begriff des ‛logischen Eigennamens’ untersucht werden. Aus dieser Sicht kann vor der Schöpfung Gottes Begriff von Individuen keine individuelle Diesheit haben, sondern nur eine vollständige Beschreibung der noch nicht existierenden Individuen. Daraus ergibt sich, daß ein und dasselbe Individuum nicht durch mehr als eine Weltbeschreibung identifiziert werden kann, und darin darf man folglich Leibniz' tatsächlichen Beweis für die These des ‛Superessentialismus’ sehen, demzufolge alle Individuen ihre gesamten Eigenschaften mit Ausnahme der (...) Existenz wesenhaft besitzen. Im weiteren wird der Begriff einer Art möglicher Welten, die wir ‛parasitisch’ nennen wollen, erforscht. Dieser Begriff wird Leibniz' theoretischen Voraussetzungen gerecht, ohne zu seinen wenig überzeugenden Schlüssen zu führen. (shrink)

Some non-reductionists claim that so-called ‘exclusion arguments’ against their position rely on a notion of causal sufficiency that is particularly problematic. I argue that such concerns about the role of causal sufficiency in exclusion arguments are relatively superficial since exclusionists can address them by reformulating exclusion arguments in terms of physical sufficiency. The resulting exclusion arguments still face familiar problems, but these are not related to the choice between causal sufficiency and physical sufficiency. The upshot (...) is that objections to the notion of causal sufficiency can be answered in a straightforward fashion and that such objections therefore do not pose a serious threat to exclusion arguments.

This paper addresses a theory of intergenerational justice that we refer to as “needs-based sufficientarianism”. According to needs-based sufficientarianism, the present generation ought to enable future generations to meet their basic needs — for example, their needs for drinkable water, food and health care. Our aim is to explain and defend this theory in a programmatic way. First, we introduce what we regard as the most plausible variant of needs-based sufficientarianism. Then we argue that this variant is superior to several (...) alternative ways of thinking about intergenerational justice. In particular, we defend basic needs as the currency of intergenerational justice and sufficiency as its principle. Our arguments for these claims are neither fully comprehensive nor fully conclusive. Yet, we hope that they suffice to show that needs-based sufficientarianism is a major contender, with significant pro tanto advantages over other views. (shrink)

Douglas Diekema influentially argues that interference with parental decisions is not in fact guided by the child’s best interests, but rather by a more permissive standard, which he calls the harm principle. This article first seeks to clarify this alternative position and defend it against certain existing criticisms, before offering a new criticism and alternative. This ‘harm principle’ has been criticized for (i) lack of adequate moral grounding, and (ii) being as indeterminate as the best interest standard that it seeks (...) to replace. I argue that these are not serious problems. I take Diekema’s negative point to be right—our actual standard for intervention is not literally the best interests of the child—but I disagree with his proposed replacement. First, Diekema’s proposed harm threshold should be more carefully distinguished from Mill’s harm principle. Second, there is no reason to assume that the standard for permissible intervention coincides with the threshold for harm (or serious harm). Thus, I propose that the best alternative to the best interests standard is not a harm principle, but rather a sufficiency threshold between adequate (or ‘good enough’) and inadequate (or ‘substandard’) parenting.

Let G be a connected graph with minimum degree δ G and vertex-connectivity κ G. The graph G is k -connected if κ G ≥ k, maximally connected if κ G = δ G, and super-connected if every minimum vertex-cut isolates a vertex of minimum degree. In this paper, we present sufficient conditions for a graph with given minimum degree to be k -connected, maximally connected, or super-connected in terms of the number of edges, the spectral radius of the graph, (...) and its complement, respectively. Analogous results for triangle-free graphs with given minimum degree to be k -connected, maximally connected, or super-connected are also presented. (shrink)

In this paper, I ask what is wrong with sufficiency. I formulate a generic sufficiency principle in relation to which I discuss possible problems for sufficientarianism. I argue against the arbitrariness–concern, that sufficiency theory need only to identify a possible space for determining a plausible threshold, and I argue against the high–low threshold dilemma concern, that multiple-threshold views can solve this dilemma. I then distinguish between currency-pluralist and currency-monist multiple-threshold views and test them against two different versions (...) of the widely shared ‘ignorance of inequality objection’ to sufficientarianism—a benefit-driven and a burden-driven version. I argue that currency-pluralist sufficiency views are better capable of responding to the former than currency-monist views. However, I show that no existing sufficiency view can provide a plausible response to the burden-driven version. Hence, I conclude that the problem of unequal distribution of burdens above the thresholds represents an overlooked threat to the sufficiency view, in any version. (shrink)

There are more refugees than many states have a duty to accept. As a result, many states are permitted to accept only some refugees and not others. This raises the question of how states should select these refugees. I defend the claim that states should resettle the worst‐off refugees, and maximize the number of refugees gaining a sufficiently decent life. When resettling the worst off conflicts with maximising the number gaining a sufficiently decent life, states should select refugees to maximise (...) aggregate benefits, with benefits holding greater weight the further refugees are from a sufficiency threshold. The only exception to this rule is when it entails wrongful discrimination, in which case states should only follow this rule if victims of discrimination benefit and consent to its implementation.

This article argues that, under likely empirical conditions, sufficientarianism leads not to an easily achievable duty to maintain a social minimum but to the onerous duty of maintaining a social maximum at the sufficiency level. This happens because sufficientarians ask us to give no weight at all to small benefits for people above the sufficiency level if the alternative is to relieve the suffering of people below it. If we apply this judgment in a world where there are (...) rare diseases and hard-to-prevent accidents that cause people to fall below the sufficiency threshold, all of our discretionary spending will have to be devoted to bringing harder and harder cases up to sufficiency. Nothing will be left for anyone to consume above the sufficiency level. (shrink)

Identity, self-sufficiency and disability in the context of educational and vocational activity This study focused on relations between identity and sense of self-sufficiency. These relations were analysed in the context of educational and vocational activity. 204 persons without disabilities and 230 persons with different kinds of disability participated in the study. Participants were divided into three groups: 18-24-year-olds - students, 25-30-year-olds - unemployed and 25-30-year-olds - employed. The results revealed that unemployed people have significant problems with identity formation. (...) This group obtained the highest scores on ruminative exploration and the lowest scores on the scales of commitment making and identification with commitment. Self-sufficiency proved to be a moderator of the relations between educational/vocational activity on the one hand and exploration in breadth and exploration in depth on the other hand. In students, level of exploration was high in individuals with a high sense of self-sufficiency whereas in the unemployed strong exploration was observed in the group with low sense of self-sufficiency. The need to conduct studies where participants are recruited from populations which seldom attract researchers' interest, such as the unemployed and people of low social status, is also noted.

There is an argument for the existence of God from the incompleteness of nature that is vaguely present in Plantinga’s recent work. This argument, which rests on the metaphysical implications of quantum physics and the philosophical deficiency of necessitarian conceptions of physical law, deserves to be given a clear formulation. The goal is to demonstrate, via a suitably articulated principle of sufficient reason, that divine action in an occasionalist mode is needed (and hence God’s existence is required) to bring causal (...) closure to nature and render it ontologically functional. The best explanation for quantum phenomena and the most adequate understanding of general providence turns out to rest on an ontic structural realism in physics that is grounded in the immaterialist metaphysics of theistic idealism.

In many-valued logics with the unit interval as the set of truth values, from the standard negation and the product (or, more generally, from any strict Frank t-norm) all measurable logical functions can be derived, provided that also operations with countable arity are allowed. The question remained open whether there are other t-norms with this property or whether all strict t-norms possess this property. We give a full solution to this problem (in the case of strict t-norms), together with convenient (...) sufficient conditions. We list several families of strict t-norms having this property and provide also counterexamples (the Hamacher product is one of them). Finally, we discuss the consequences of these results for the characterization of tribes based on strict t-norms. (shrink)
