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).

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)

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.

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)

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.

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.

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)

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.

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 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.

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)

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.

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)

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)

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.

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)

Matteo Bonotti’s book on Partisanship and Public Reason in Diverse Societies is grounded on a theory of partisanship that sees the demands of public reason as internal to the very definition of a party. Bonotti suggests that partisanship is not only compatible with but essential to the stability and legitimacy of a well-ordered liberal society. My paper aims to raise some questions internal to the liberal account of partisanship so as to probe the methodological foundations and plausibility of the liberal (...) framework taken as a whole. My argument is that the assumption of a sufficiently just liberal society on which the book grounds its defence of partisanship makes us ill-equipped to face some of the most critical challenges that liberal societies face in the world that we live.

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)

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.

Sufficientarian theories of distributive justice are often considered to be vulnerable to the ‘blindness to inequality and other values objection’. This objection targets their commitment to holding the moral irrelevance of requirements of justice above absolute thresholds of advantage, making them insufficiently sensitive to egalitarian moral concerns that do have relevance for justice. This paper explores how sufficientarians could reply to this objection. Particularly, I claim that, if we accept that the force of the aforementioned objection comes from relational, and (...) not distributive, inequalities, different strategies are open for sufficientarians in order to be sensitive to these concerns. Drawing on recent literature about the relation between distributive and relational egalitarianism, and the possibility of reducing one to the other, strategies of ‘internalizing’ and ‘externalizing’ relational egalitarian concerns to a distributive sufficientarian framework are explored. In turn, I suggest that both strategies fail in their standard versions, but argue that a particular ‘hybrid view’ about justice is an attractive candidate for the sufficientarian theorist. (shrink)

Climate change highlights the relevance of population ethics. Should we attempt to maximize the combined welfare of future people? Many versions of Utilitarianism hold that we should. However, most Utilitarian theories have quite unpleasant implications when applied to all future generations.In this article, I consider the prospects for a Telic Sufficientarian theory of welfare . According to this theory, shortfalls from a sufficient level of welfare are morally bad, and this is all that matters as far as welfare is concerned (...) . Telic Sufficientarianism avoids the familiar problems haunting Utilitarian theories, but runs into trouble elsewhere. I argue that these problems are not fatal to the view. (shrink)

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)

Some passages throughout Spinoza’s body of works suggest that an attribute in its absolute nature provides a sufficient condition for all of its modes, including the finite ones. Other passages suggest that an attribute in its absolute nature fails to provide a sufficient condition for its finite modes. My aim is to dispel this apparent tension. I argue that all finite modes are ultimately entailed by the absolute nature of their attribute. Furthermore, I explain how the Spinozistic positions that appear (...) incompatible with this view are in fact compatible. As I see it, we should read those passages where Spinoza says that no finite mode ultimately follows from the absolute nature of its attribute as saying merely that no finite mode ultimately follows in one-by-one fashion, independent of an infinite series of other modes, from the absolute nature of its attribute.

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.

In a series of publications E.J. Lowe has advocated an attractive alternative to the orthodox view about conditionals embodied in the Stalnaker-Lewis approach. One alleged advantage of Lowe’s approach over its rival is that it offers the prospect of a simpler conditional logic. Another related advantage is that it appears to treat inference by transitivity more plausibly than does the Stalnaker-Lewis approach. One central goal of this paper is to call into question Lowe’s success in providing an account that is (...) better than the Stalnaker-Lewis account in these respects. As part of this, I develop a Loweian-inspired account of sufficient condition sentences such as ‘Harry’s eating this apple is a sufficient condition for his getting sick’, which is another central goal of the paper.

According to the Principle of Sufficient Reason (henceforth ‘PSR’), everything has an explanation or sufficient reason. This paper addresses three questions. First, how continuous is the contemporary notion of grounding with the notion of sufficient reason endorsed by Spinoza, Leibniz, and other rationalists? In particular, does a PSR formulated in terms of ground retain the intuitive pull and power of the PSR endorsed by the rationalists? Second, to what extent can the PSR avoid the formidable traditional objections levelled against it (...) if it is formulated in terms of ground? And finally, how might historical discussion of the PSR shed light on the contemporary notion of grounding? (shrink)

What, if anything, do we owe others as a basic minimum? Sufficiency theorists claim that we must provide everyone with enough – but, to date, few well-worked-out accounts of the sufficiency threshold exist, so it is difficult to evaluate this proposition. Previous theories do not provide plausible, independent accounts of resources, capabilities, or welfare that might play the requisite role. Moreover, I believe existing accounts do not provide nearly enough guidance for policymakers. So, this article sketches a mechanism (...) for arriving at an account of the minimally good life that can help locate the sufficiency threshold. (shrink)

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.

Most of the historically salient versions of the Cosmological Argument rest on two assumptions. The first assumption is that some contingeney (i.e., contingent fact) is such that a necessity is required to explain it. Against that assumption we will argue that necessities alone cannot explain any contingency and, furthermore, that it is impossible to explain the totality of contingencies at all.The second assumption is the Principle of Sufficient Reason. Against the Principle of Sufficient Reason we will argue that it is (...) unreasonable to require, as the Principle of Sufficient Reason does, that any given whole of contingent facts has an explanation. Instead, it depends on the results of empirical investigation whether or not one should ask for an explanation of the given whole.We argue that if a cosmological argument invokes either of the two assumptions, then it fails to prove that a necessity is needed to explain the universe of contingent facts.

The Principle of Sufficient Reason is a powerful and controversial philosophical principle stipulating that everything must have a reason or cause. This simple demand for thoroughgoing intelligibility yields some of the boldest and most challenging theses in the history of metaphysics and epistemology. In this entry we begin with explaining the Principle, and then turn to the history of the debates around it. A section on recent discussions of the Principle will be added in the near future.

This little-known work by the famous German pessimist and critic of Hegel was originally written as a doctoral dissertation when Schopenhauer was just twenty-six, but it was later revised when the philosopher was sixty. So important did he consider this work, originally titled "On the Fourfold Root of the Principle of Sufficient Reason," that he often underscored the fact that no one could hope to understand his magnum opus, The World as Will and Representation, without having first read this work. (...) Schopenhauer takes up where Kant left off in response to Hume, and his insights into the nature of perception and understanding remain amazingly relevant and still unsurpassed. Schopenhauer's analyses of causation and related concepts rival and probably surpass in their depth and brilliance the more celebrated discussions of David Hume. Where Hume grossly oversimplified these problems and left them riddled with paradoxes, Schopenhauer disentangled them and shed light on what had seemed hopelessly dark. (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.

We consider the problems arising from using sequences of experiments to discover the causal structure among a set of variables, none of whom are known ahead of time to be an “outcome”. In particular, we present various approaches to resolve conflicts in the experimental results arising from sampling variability in the experiments. We provide a sufficient condition that allows for pooling of data from experiments with different joint distributions over the variables. Satisfaction of the condition allows for an independence test (...) with greater sample size that may resolve some of the conflicts in the experimental results. The pooling condition has its own problems, but should—due to its generality—be informative to techniques for meta-analysis. (shrink)

This paper defends a simple thesis: that knowledge is belief for reasons that are both objectively and subjectively sufficient. I take a dogmatic approach, devoting the bulk of the paper to an explanation of what this means, and of why it explains both what knowledge is like, and why it is important; the theory is justified by its fruits. I go on to illustrate, by appeal to my main thesis, how knowledge comes to play some of the key roles that (...) it does, including looking at Williamson’s arguments that knowledge is prime and for its distinctive explanatory role, as well as why my account explains and predicts the complicated behavior of knowledge in cases involving defeaters, defeated defeaters, and defeaters whose defeaters are defeated, as well as the different possible kinds of defeat – the primary source of complications in the Gettier literature. These facts are easily explained by the central thesis of the paper, without either giving up on the analysis of knowledge or resorting to arbitrary or ad hoc measures. Since the last five decades of literature might lead one to find it fairly audacious to propose an analysis of knowledge, a final section addresses the putative inductive grounds for general pessimism about the Gettierological project.

It is traditional to ascribe to Locke the view that every person who acquires natural property rights by labouring on resources is obligated to leave sufficient resources for everyone else. But during the last several decades, a number of authors have contributed to a compelling textual case against this reading. Nevertheless, Locke clearly indicates that there is something wrong with distributions in which some suffer while others thrive. But if he does not endorse the traditional proviso, what exactly is the (...) problem? In this paper, I offer a solution to this puzzle. I argue that according to Locke, once people use their natural rights to acquire large properties, many individuals are unable to enjoy the material and moral wellbeing, or “preservation,” that is the end of natural law. For even if such large properties pose no problem for material preservation, they foster arbitrary power that offends against moral preservation. (shrink)

Toward the end of his classic treatise An Essay on Free Will, Peter van Inwagen offers a modal argument against the Principle of Sufficient Reason which he argues shows that the principle “collapses all modal distinctions.” In this paper, a critical flaw in this argument is shown to lie in van Inwagen’s beginning assumption that there is such a thing as the conjunction of all contingently true propositions. This is shown to follow from Cantor’s theorem and a property of conjunction (...) with respect to contingent propositions. Given the failure of this assumption, van Inwagen’s argument against the Principle of Sufficient Reason cannot succeed, at least not without the addition of some remarkable and previously unacknowledged qualifications.

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.

Aristotle tells us that contemplation is the most self-sufficient form of virtuous activity: we can contemplate alone, and with minimal resources, while moral virtues like courage require other individuals to be courageous towards, or courageous with. This is hard to square with the rest of his discussion of self-sufficiency in the Ethics: Aristotle doesn't generally seek to minimize the number of resources necessary for a flourishing human life, and seems happy to grant that such a life will be self-sufficient (...) despite requiring a lot of external goods. In this paper I develop an interpretation of self-sufficiency as a form of independence from external contributors to our activity, and argue that this interpretation accounts both for Aristotle's views on contemplation and for the role self-sufficiency plays in his broader account of human happiness.

Leibniz was a philosopher of principles: the principles of Contradiction, of Sufficient Reason, of Identity of Indiscernibles, of Plenitude, of the Best, and of Continuity are among the most famous Leibnizian principles. In this article I shall focus on the first three principles; I shall discuss various formulations of the principles (sect. 1), what it means for these theses to have the status of principles or axioms in Leibniz’s philosophy (sect. 2), the fundamental character of the Principles of Contradiction and (...) Sufficient Reason (sect. 3), some attempts to demonstrate the Principles of Contradiction and Sufficient Reason (sect. 4), and one attempt to demonstrate the Principle of Identity of Indiscernibles (sect. 5). The main results of the chapter are summarized in a short conclusion (sect. 6). (shrink)

The distinction between equality and sufficiency, much discussed in the distributive justice literature, is here applied to democratic theory. Overlooking this distinction can have significant normative implications, undermining some defences and criticisms of political equality, as I show by discussing the work of three prominent democratic theorists: Thomas Christiano, David Estlund, and Mark Warren. Most importantly, Christiano sometimes defends egalitarian conclusions using sufficientarian premises, or worries about inequality in situations where insufficiency is also part of the problem; inequality above (...) the level of sufficiency is not always as troubling. Estlund makes the reverse error. He attacks rather than defends political egalitarianism, but insufficiency seems to explain some of his concerns. Nonetheless, I show that political egalitarians may need to specify a sufficientarian threshold, to avoid levelling-down objections. Democratic theorists should thus take seriously the distinction between political equality and political sufficiency. More generally, political theorists and philosophers should be aware of omitted variable bias and interaction effects due to conceptual stretching arising from under-theorised distinctions in their thought experiments.
