In normative political theory, it is widely accepted that democracy cannot be reduced to voting alone, but that it requires deliberation. In formal social choice theory, by contrast, the study of democracy has focused primarily on the aggregation of individual opinions into collective decisions, typically through voting. While the literature on deliberation has an optimistic flavour, the literature on social choice is more mixed. It is centred around several paradoxes and impossibility results identifying conflicts between different intuitively plausible desiderata. In (...) recent years, there has been a growing dialogue between the two literatures. This paper discusses the connections between them. Important insights are that (i) deliberation can complement aggregation and open up an escape route from some of its negative results; and (ii) the formal models of social choice theory can shed light on some aspects of deliberation, such as the nature of deliberation-induced opinion change.

The 2005 International Consensus Conference on Intersex resulted in a substantive revision of the lexicon and guidelines for treating intersex conditions. The speed with which the new treatment protocol has been adopted by healthcare practitioners and providers is considered unprecedented. However, a number of intersex people and advocacy groups have complained that the recommended revisions are inadequately informed by the testimony of intersex people. In this paper, I argue that such complaints are valid and that, despite the conference (...) conveners stated intention, the revisions perpetuate the epistemic injustice long endured by intersex people. By analyzing the Consensus Conference and its results as a failed attempt to redress the epistemic marginalization of intersex patients and advocacy groups, I am able to identify lingering institutional hurdles to cultivating the virtue of epistemic justice in biomedical practice.

There is consensus among computer scientists, logicians, and philosophers that good reasoning with qualitative beliefs must have the structural property of cumulative transitivity or, for short, cut. This consensus is typically explicitly argued for partially on the basis of practical and mathematical considerations. But the consensus is also implicit in the approach philosophers take to almost every puzzle about reasoning that involves multiple steps: philosophers typically assume that if each step in reasoning is acceptable considered on its (...) own, the whole chain of reasoning must also acceptable. In this paper I focus on whether there are good philosophical reasons for thinking that the consensus that good reasoning must satisfy cut is true. My central claim is that we should not accept the consensus—good reasoning might not satisfy cut. In particular, I consider four arguments for the consensus and explain why they are unpersuasive. (§2-5). I then show that the issue of whether good reasoning is cut turns on a substantive yet until now unnoticed question in epistemology (§6). (shrink)

Public reason liberalism is the political theory which holds that coercive laws and policies are justified when and only when they are grounded in reasons of the public. The standard interpretation of public reason liberalism, consensus accounts, claim that the reasons persons share or that persons can derive from shared values determine which policies can be justified. In this paper, I argue that consensus approaches cannot justify fair educational policies and preserving cultural goods. Consensus approaches can resolve (...) some controversies about teaching values in the educational system, such as curriculum choice. But they cannot determine which culture goods, e.g., architecture, artwork, or language ought to be preserved in the education system. Consensus approaches cannot fairly resolve competing claims about these kinds of disputes. -/- I propose that convergence accounts of public reason, which allow individuals to draw on their own comprehensive doctrines in limited ways, can remedy these weaknesses in the mainline public reason tradition. The convergence approach can justify a pluralist state that can advance valuable community goods. John Henry Newman’s advocacy of liberal arts education finds resonance in other cultures, notably among Confucians, illustrating that there can be a shared moral vision and inquiry into the good life across deep substantive disagreements about educational values and policies, once we expand our notion of justification to be more inclusive.

Legal philosophers and property scholars sometimes disagree over one or more of the following: the meaning of the word 'property,' the concept of property, and the nature of property. For much of the twentieth century, the work of W.N. Hohfeld and Tony Honoré represented a consensus around property. The consensus often went under the heading of property as bundle of rights, or more accurately as a set of normative relations between persons with respect to things. But by the (...) mid-l 990s, the consensus was under attack. Key figures in the attack were James Penner, a legal philosopher, and Thomas W. Merrill and Henry E. Smith, two highly regarded professors of property law. This article aims to repel the attack and argues for property as a set of normative relations between persons with respect to things. The positive case for this view of property pays special attention to the philosophy of language and the analysis of concepts. The positive case also maintains that the right to use and the power to transfer are as central to property as the right to exclude. It is possible that the virtues of Smith's modular theory of property differ from the virtues of a well-crafted bundle theory. Indeed, it may be the case that these two theories throw light on different features of property law and are not, save at the margin, competitors with each other. The label 'new essentialism' sometimes applied to the work of Penner, Merrill, and Smith seems inapt if property does not have an essence. Of course, they might refuse the label. (shrink)

There has been a long history of arguments over whether happiness is anything more than a particular set of psychological states. On one side, some philosophers have argued that there is not, endorsing a descriptive view of happiness. Affective scientists have also embraced this view and are reaching a near consensus on a definition of happiness as some combination of affect and life-satisfaction. On the other side, some philosophers have maintained an evaluative view of happiness, on which being happy (...) involves living a life that is normatively good. Within the context of this debate we consider how people ordinarily understand happiness, and provide evidence that the ordinary understanding of happiness reflects aspects of both evaluative and descriptive views. Similar to evaluative views, normative judgments have a substantive role in the ordinary understanding of happiness. Yet, similar to descriptive views, the ordinary understanding is focused on the person’s psychological states and not the overall life they actually lived. Combining these two aspects, we argue that the ordinary understanding of happiness suggests a novel view on which happiness consists in experiencing positive psychological states when one ought to. This view, if right, has implications for both philosophical and psychological research on happiness. (shrink)

In this paper, I want to focus not on the problems that I believe may threaten Kant’s account of the highest good, but instead on those that I believe threaten the majority of the interpretive reconstructions attempted by commentators and thus prevent the emergence of a consensus in the near future. My goal is to set forth exactly four problems to which I believe any successful interpretation or reconstruction of Kant’s account of the highest good will have to provide (...) substantive solutions and, in doing so, either break new theoretical ground or at least provide a more comprehensive methodology for sorting through the texts.

Since the ENCODE project published its final results in a series of articles in 2012, there is no consensus on what its implications are. ENCODE’s central and most controversial claim was that there is essentially no junk DNA: most sections of the human genome believed to be «junk» are functional. This claim was met with many reservations. If researchers disagree about whether there is junk DNA, they have first to agree on a concept of function and how function, given (...) a particular definition, can be discovered. The ENCODE debate centered on a notion of function that assumes a strong dichotomy between evolutionary and non-evolutionary function and causes, prevalent in the Modern Evolutionary Synthesis. In contrast to how the debate is typically portrayed, both sides share a commitment to this distinction. This distinction is, however, much debated in alternative approaches to evolutionary theory, such as the EES. We show that because the ENCODE debate is grounded in a particular notion of function, it is unclear how it connects to broader debates about what is the correct evolutionary frame- work. Furthermore, we show how arguments brought forward in the controversy, particularly arguments from mathematical population genetics, are deeply embedded in their particular disciplinary contexts, and reflect substantive assumptions about the evolution of genomes. With this article, we aim to provide an anatomy of the ENCODE debate that offers a new perspective on the notions of function both sides employed, as well as to situate the ENCODE debate within wider debates regarding the forces operating in evolution.

(In German.) The book addresses Rawls's post-1985 political liberalism. His justification of political liberalism -- as reflected in his arguments from overlapping consensus -- faces the problem that liberal content can be justified as reciprocally acceptable only if the addressees of such a justification already endorse points of view that suitably support liberal ideas. Rawls responds to this legitimacy-theoretical problem by restricting public justification's scope to include reasonable people only, while implicitly defining reasonableness as a substantive liberal virtue. (...) But this virtue-ethical grounding of political liberalism is itself unreasonable. The phenomenon of disharmony of practical reason gives the reasonable reasons to take it that political legitimacy does not obtain if and where moral-political principles are acceptable from their point of view only.

Majority cycling and related social choice paradoxes are often thought to threaten the meaningfulness of democracy. But deliberation can prevent majority cycles – not by inducing unanimity, which is unrealistic, but by bringing preferences closer to single-peakedness. We present the first empirical test of this hypothesis, using data from Deliberative Polls. Comparing preferences before and after deliberation, we find increases in proximity to single-peakedness. The increases are greater for lower versus higher salience issues and for individuals who seem to have (...) deliberated more versus less effectively. They are not merely a byproduct of increased substantive agreement. Our results both refine and support the idea that deliberation, by increasing proximity to single-peakedness, provides an escape from the problem of majority cycling. (shrink)

From the Qur'an, Surah Maryam: -/- (21) So she conceived him, and went in seclusion with him to a remote place. (22) And the pains of childbirth drove her to the trunk of a palm tree: she cried (in her anguish): "Ah! would that I had died before this! Would that I had been a thing forgotten and out of sight!" (23) But (a voice) cried to her from beneath the (palm tree): "Grieve not! for thy Lord hath provided a (...) rivulet beneath thee;" (24) "And shake towards thyself the trunk of the palm tree: it will let fall fresh ripe dates upon thee." (25) "So eat and drink and cool (thine) eye. And if thou dost see any man say 'I have vowed a fast to (Allah) Most Gracious, and this day will I enter into no talk with any human being.'" -/- This Surah depicts a human being in unbearable pain. What makes the pain tolerable is the sympathy that God shows for Mary. Hearing her inner voice, understanding her suffering and her grief, God is moved to provide her with practical and substantive support to help her bear her agony. For me this story portrays a God who is active in the world, hears the supplications of humanity, and has empathy with the needy, the oppressed, and those who are suffering. -/- Yet I am concerned that our theological traditions in the Islamic world (as also in Christendom) have developed through the centuries such that God is now seen, by overwhelming theological consensus, as an immutable being, a being outside time who has determined our providence from the standpoint of eternity, who has foreknowledge of every free action of his creations and has designed all according to His plan for past and future events; who knows in advance even the timings and contents of our petitionary prayers and has decided already whether to answer them.

The link between human nature and human flourishing is undeniable. "A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit" (Matt. 7:18). The ontology of the human person will, therefore, ground the nature of human flourishing and thereby sanctification. Spiritual formation is the area of Christian theology that studies sanctification, the Spirit-guided process whereby disciples of Jesus are formed into the image of Jesus (Rom. 8:28-29; 2 Cor. 3:18; 2 Peter 3:18). Until the nineteenth century, (...) there was an overwhelming consensus among Christian thinkers that some form of mind-body (or soul-body) dualism is true of human beings. Recently, that consensus has eroded, and with it the availability of a shared body of knowledge about spiritual formation. Some Christian physicalists argue that dualism is incompatible with central elements of spiritual formation. Neuroscientist Warren Brown and psychologist Brad Strawn offer the only substantive account of spiritual formation from the view of Christian physicalism and its accompanying objections to dualism. It is on their arguments that this chapter focuses. We argue that Brown and Strawn fail to support their incompatibility thesis. Additionally, we argue that Christian physicalism stands in tension with important philosophical and theological foundations of Christian spiritual formation. In doing so we offer a specific form of dualism, the bodily soul view, and explain how this view illuminates the importance of embodiment, our neurological and social development, and hence the important physical aspects of Christian spiritual formation.

Is there an ethics of creativity? Though this question appears innocent enough, it proves surprisingly difficult to answer. A survey of the literature on the topic reveals that process ethics has variously been categorized as or seen as compatible with: moral interest theory, ecological virtue ethics, utilitarianism, Confucian virtue ethics, and even deontology. What can account for such divergent and even contradictory conclusions? On one level we might blame Whitehead, whose sporadic comments on morality may appear to be more suggestive (...) than systematic. While, as I argue elsewhere,3 there is a greater coherence to Whitehead’s statements about morality than is initially apparent, it is undeniable that he never attempted to develop a theory of morality. Yet it is unlikely that the state of the texts should shoulder all of the blame for the lack of consensus on the basic nature of process ethics. It would seem that there is a more fundamental problem lurking beneath the surface. Indeed, I suggest that there are at least five basic confusions — four substantive and one methodological — that have vitiated attempts to understand and develop a process approach to morality. Until these confusions are recognized and resolved, we will have no hope of understanding the promise or realizing the potential of the ethics of creativity. (shrink)

The addiction literature is fraught with conceptual confusions, stalled debates, and an unfortunate lack of clear and careful attempts to delineate the phenomenon of addiction in a way that might lead to consensus. My dissertation has two overarching aims, one metaphysical and one practical. -/- The first aim is to defend an account of addiction as the systematic disposition to fail to control one’s desires to engage in certain types of behaviors. I defend the inclusion of desires and impaired (...) control in the definition, and I flesh out the notion of systematicity central to my dispositionalist framework. I engage the so-called ‘disease vs. choice’ debate, criticizing its presupposition that we are dealing here with a dichotomy and arguing that the movement towards a middle ground is the right track to take. I explain how the dispositionalist account can capture this middle ground and how it serves to expand upon existing views, in particular by filling in the metaphysical details. -/- The second aim is to show how the account I defend can help to unify the extant views and disciplinary perspectives in the literature. Both the dispositionalist aspect of my framework and the methodology adopted (applied ontology and systematic metaphysics) can move the literature towards both substantive and methodological unification. This will help to clear up conceptual confusions, resolve (or sometimes dissolve) apparently intractable disputes, situate different research perspectives with respect to each other, facilitate interdisciplinary dialogue, and help to frame important questions about addiction. Finally, I offer the beginnings of an ontology of addiction, which will provide a terminologically well-structured guide to the addiction literature in a way that will facilitate more effective and efficient communication and data management across disciplines.

Consensus and disagreement play important roles in the practice, development, and dissemination of science. This raises a host of important philosophical questions. Some of these issues are conceptual: When, exactly, does a scientific agreement count as a consensus? And in what sense, if any, is disagreement the opposite of consensus? Other questions concern the role of consensus and disagreement in the development of science: For example, is consensus on central methodological issues and assumptions necessary for (...) scientific work to proceed normally? Yet other questions are epistemological: From a layperson’s perspective, does the presence of a scientific consensus ever indicate that the relevant theory is probably correct? If so, what are the conditions under which it does so? Relatedly, should scientists themselves also defer to the consensus position among their peers whenever such a consensus exists? Or should they instead evaluate consensus theories for themselves, or even actively aim to dissent against such theories? (shrink)

Could the notion of compromise help us overcoming – or at least negotiating – the frequent tension, in normative political theory, between the realistic desideratum of peaceful coexistence and the idealistic desideratum of justice? That is to say, an analysis of compromise may help us moving beyond the contrast between two widespread contrasting attitudes in contemporary political philosophy: ‘fiat iustitia, pereat mundus’ on the one side, ‘salus populi suprema lex’ on the other side. More specifically, compromise may provide the backbone (...) of a conception of legitimacy that mediates between idealistic (or moralistic) and realistic (or pragmatic) desiderata of political theory, i.e. between the aspiration to peace and the aspiration to justice. In other words, this paper considers whether an account of compromise could feature in a viable realistic conception of political legitimacy, in much the same way in which consensus features in more idealistic conceptions of legitimacy (a move that may be attributed to some realist theorists, especially Bernard Williams). My conclusions, however, are largely sceptical: I argue that grounding legitimacy in any kind of normatively salient agreement does require the trappings of idealistic political philosophy, for better or – in my view – worse.

A consensus in a scientific community is often used as a resource for making informed public-policy decisions and deciding between rival expert testimonies in legal trials. This paper contains a social-epistemic analysis of the high-profile Bendectin drug controversy, which was decided in the courtroom inter alia by deference to a scientific consensus about the safety of Bendectin. Drawing on my previously developed account of knowledge-based consensus, I argue that the consensus in this case was not knowledge (...) based, hence courts’ deference to it was not epistemically justified. I draw sceptical lessons from this analysis regarding the value of scientific consensus as a desirable and reliable means of resolving scientific controversies in public life. (shrink)

Around 97% of climate scientists endorse anthropogenic global warming (AGW), the theory that human activities are partly responsible for recent increases in global average temperatures. Clearly, this widespread endorsement of AGW is a reason for non-experts to believe in AGW. But what is the epistemic significance of the fact that some climate scientists do not endorse AGW? This paper contrasts expert unanimity, in which virtually no expert disagrees with some theory, with expert consensus, in which some non-negligible proportion either (...) rejects or is uncertain about the theory. It is argued that, from a layperson’s point of view, an expert consensus is often stronger evidence for a theory’s truth than unanimity. Several lessons are drawn from this conclusion, e.g. concerning what laypeople should infer from expert pronouncements, how journalists should report on scientific theories, and how working scientists should communicate with the public.

There has been an explosion of interest in the metaphysics of fundamentality in recent decades. The consensus view, called metaphysical foundationalism, maintains that there is something absolutely fundamental in reality upon which everything else depends. However, a number of thinkers have chal- lenged the arguments in favor of foundationalism and have proposed competing non-foundationalist ontologies. This paper provides a systematic and critical introduction to metaphysical foundationalism in the current literature and argues that its relation to ontological dependence and substance (...) should be qualified in important ways.

Social metaphysics is a source of important philosophical and moral insight. Furthermore, much social metaphysics appears to be substantive. However, some have recently argued that standard views of metaphysics cannot accommodate substantive social metaphysics. In this paper I offer a new diagnosis of this problem and defend a new solution, showing that this problem is an illuminating lens through which to examine the nature and boundaries of metaphysics. This case instantiates a broad, common pattern generated by attempts to (...) align distinctions between realism and anti-realism, mind-independence and mind-dependence, and legitimate and non-legitimate inquiry. I show that the best response is to abandon the association between substantive metaphysics and mind-independence, and I sketch a new definition of substantivity, given in terms of explanatory power, that makes room for substantive social metaphysics while also offering an attractive basis for general metaphysics.

In this paper, I try to show that democratic consensus – one of the more prominent ideals in recent political thought – is an essential byproduct of epistemically warranted beliefs about political action and organization, at least in those cases where the issues under dispute are epistemic in nature. An essential byproduct (to borrow Jon Elster’s term) is a goal that can only be intentionally achieved by aiming at some other objective. In my usage, a political issue is epistemic (...) when there is some right (or at least best) answer concerning how it ought to be resolved that is independent of people’s beliefs or desires about how it ought to be resolved. An important secondary claim, then, is that it is difficult to explain the presumptive value of political deliberation unless we understand a very large share of political issues as epistemic in nature. This view implies a considerably more contentious model of political deliberation but is not incompatible with familiar forms of conciliatory behavior in our public disputes. (shrink)

Progress in addiction science is hampered by disagreements and ambiguity around its core construct: addiction. Addiction Ontology (AddictO) offers a path to a solution of the kind that has addressed similar problems in other areas of science: a set of clearly and uniquely defined entities to which terms such as ‘addiction’, addictive disorder’ and ‘substance dependence ’can be applied for ease of reference while recognizing that it is the construct definitions and their unique IDs that are central, not the terms.

In this paper, I wish to criticize the notion that consensus is an epistemology. While I have never seen it explicitly claimed that “consensus is an epistemology,” I have nonetheless seen it implied in many scholarly (and layperson) articles. This occurs whenever articles cite, “a majority of scholars agree that…” or “most scientists/researchers think…” In our democratic, individualistic society, we put a value on high value votes and the quantification of majority viewpoints, whether it be in political polls (...) (due to living in a democracy), online on websites with ranking or voting systems such as Reddit, YouTube, or Instagram. The danger here is we may defer too much to the consensus view without appropriate justification. I will give several reasons why we should be skeptical of appeals to consensus (including a consensus of experts), which include its non-obvious link to ontology, the fact that consensus changes, and a lack of specificity of who counts as an ``expert,'' the lack of specificity on how to handle consensus (if it does occur), and epistemic undercutting defeaters from evolutionary epistemology. While an appeal to consensus may not tell us much about whether a theory is true, they can give us practical or pragmatic reasons for trusting a position. (shrink)

Scientific consensus is widely deferred to in public debates as a social indicator of the existence of knowledge. However, it is far from clear that such deference to consensus is always justified. The existence of agreement in a community of researchers is a contingent fact, and researchers may reach a consensus for all kinds of reasons, such as fighting a common foe or sharing a common bias. Scientific consensus, by itself, does not necessarily indicate the existence (...) of shared knowledge among the members of the consensus community. I address the question of under what conditions it is likely that a consensus is in fact knowledge based. I argue that a consensus is likely to be knowledge based when knowledge is the best explanation of the consensus, and I identify three conditions—social calibration, apparent consilience of evidence, and social diversity, for knowledge being the best explanation of a consensus.

This essay critically assesses the central claim of Kevin Vallier’s Liberal Politics and Public Faith: that public religious faith and public reason liberalism can be reconciled, because the values underlying public reason liberalism should lead us to endorse the ‘convergence view’, rather than the mainstream consensus view. The convergence view is friendlier to religious faith, because it jettisons the consensus view’s much-criticised ‘duty of restraint’. I present several challenges to Vallier’s claim. Firstly, if Vallier is right to reject (...) the duty of restraint then consensus theorists can also do so, and on the same grounds. Secondly, the independent force of the objections to the duty of restraint is unclear. Thirdly, Vallier has not successfully identified desiderata that unite all public reason liberals and favour convergence over consensus. Finally, even if convergence is in some ways friendlier to religious faith, this does not show that it will be attractive to religious citizens. (shrink)

Consensus conferences are social techniques which involve bringing together a group of scientific experts, and sometimes also non-experts, in order to increase the public role in science and related policy, to amalgamate diverse and often contradictory evidence for a hypothesis of interest, and to achieve scientific consensus or at least the appearance of consensus among scientists. For consensus conferences that set out to amalgamate evidence, I propose three desiderata: Inclusivity, Constraint, and Evidential Complexity. Two examples suggest (...) that consensus conferences can readily satisfy Inclusivity and Evidential Complexity, but consensus conferences do not as easily satisfy Constraint. I end by discussing the relation between social inclusivity and the three desiderata. (shrink)

In Philosophy for Children (P4C), consensus-making is often regarded as something that needs to be avoided. P4C scholars believe that consensus-making would dismiss P4C’s ideals, such as freedom, inclusiveness, and diversity. This paper aims to counteract such assumptions, arguing that P4C scholars tend to focus on a narrow, or universal, concept of “consensus” and dismiss various forms of consensus, especially what Niemeyer and Dryzek (2007) call meta-consensus. Meta-consensus does not search for universal consensus, (...) but focuses on the process by which people achieve various non-universal forms of consensus, such as agreement on the value of opponents’ normative view or agreement on the degree to which they accept opponents’ view. This paper argues that such meta-consensus is a key part of what Clinton Golding (2009) calls “philosophical progress,” which is the essential element that makes inquiry philosophical. In other words, without meta-consensus and philosophical progress, inquiry ends in merely conversation or antagonistic talk. Drawing on the example of P4C conducted with Japanese students, this paper shows how meta-consensus is achieved in the community of philosophical inquiry and how it contributes to make inquiry philosophical.

All morally wrong actions deserve some form of moral condemnation. But the degree of that condemnation is not the same in all cases. Some wrongs are so morally extreme that they seem to belong to a different category because they deserve our very strongest form of moral condemnation. For example, telling a white lie to make a friend feel better might be morally wrong, but intuitively such an act is in a different moral category to the sadistic, brutal, and violent (...) rape and torture of a child. The former act is merely wrong and not evil. In contrast, the latter act seems so morally extreme that we need to call it “evil” and not merely “wrong” if we are to do justice both to the moral seriousness of that act and the strength of our condemnation of it. The task of a theory or substantive conception of evil is to spell out what is an evil action and how it differs from a merely wrongful action. But what does a plausible substantive theory of evil look like? To explore this question, I spell out the concept of evil and illustrate four different types of substantive conceptions of evil actions: victim, perpetrator, spectator, and mixed theories. Of these four options, I argue that mixed theories are the most plausible type of theory, before investigating in detail the promising mixed theory recently defended by Matthew Kramer (2014b). Finally, in light of my analysis of Kramer’s view, I present a reformulated version of my combination theory of evil (Formosa 2008; Formosa 2013). (shrink)

(c) Should we not value the art of closure, of finding ways to make agreements, particularly in view of the dire state of world politics today? We use this opportunity to highlight and further develop some of (...) our ideas. (shrink)

We often remember in groups, yet research on collaborative recall finds “collaborative inhibition”: Recalling with others has costs compared to recalling alone. In related paradigms, remembering with others introduces errors into recall. We compared costs and benefits of two collaboration procedures—turn taking and consensus. First, 135 individuals learned a word list and recalled it alone (Recall 1). Then, 45 participants in three-member groups took turns to recall, 45 participants in three-member groups reached a consensus, and 45 participants recalled (...) alone but were analysed as three-member nominal groups (Recall 2). Finally, all participants recalled alone (Recall 3). Both turn-taking and consensus groups demonstrated the usual pattern of costs during collaboration and benefits after collaboration in terms of recall completeness. However, consensus groups, and not turn-taking groups, demonstrated clear benefits in terms of recall accuracy, both during and after collaboration. Consensus groups engaged in beneficial group source-monitoring processes. Our findings challenge assumptions about the negative consequences of social remembering. (shrink)

Merging of opinions results underwrite Bayesian rejoinders to complaints about the subjective nature of personal probability. Such results establish that sufficiently similar priors achieve consensus in the long run when fed the same increasing stream of evidence. Initial subjectivity, the line goes, is of mere transient significance, giving way to intersubjective agreement eventually. Here, we establish a merging result for sets of probability measures that are updated by Jeffrey conditioning. This generalizes a number of different merging results in the (...) literature. We also show that such sets converge to a shared, maximally informed opinion. Convergence to a maximally informed opinion is a (weak) Jeffrey conditioning analogue of Bayesian “convergence to the truth” for conditional probabilities. Finally, we demonstrate the philosophical significance of our study by detailing applications to the topics of dynamic coherence, imprecise probabilities, and probabilistic opinion pooling. (shrink)

There are several strategies for exposing the defects of established moral discourse, one of which is critical argumentation. However, under certain specific historical circumstances, the apparent self-evidence of established moral discourse has gained such dominance, such a capacity of resistance or incorporation, such an ability to conceal its basic vulnerability that its validity simply seems beyond contestation. Notwithstanding the moral subject’s basic discontent, he or she remains unable to challenge the dominant discourse effectively by means of critical argument. Or, to (...) borrow a phrase from Michel Foucault, individuals find themselves faced with a certain rationality, a moral regime that dominates moral discourse to such an extent that they cannot offer any resistance without raising the suspicion of being unreasonable. They (that is, we) find ourselves confronted with a discourse quite unable to recognize its own deficiencies. Although we are forced to accept its basic claims, our chronic discontent nevertheless persists. That is, although we are forced to participate in this discourse, we remain basically ambivalent, and our attitude towards established morality contains both a Yes and a No. Then, all of a sudden, the basic vulnerability of the dominant regime dawns on us or is revealed to us – and this is the experience of laughter.

When philosophers, social scientists, and politicians seek to determine the justice of institutional arrangements, their discussions have often taken the form of questioning whether and under what circumstances the redistribution of wealth or other valuable goods is justified. This essay examines the different ways in which redistribution can be understood, the diverse political contexts in which it has been employed, and whether or not it is a useful concept for exploring questions of distributive justice.

Unlike other organs that operate continuously, such as the heart and kidneys, many of the operations of the nervous system shut down during sleep. The evolutionarily conserved unconscious state of sleep that puts animals at risk from predators indicates that it is an indispensable integral part of systems operation. A reasonable expectation is that any hypothesis for the mechanism of the nervous system functions should be able to provide an explanation for sleep. In this regard, the semblance hypothesis is examined. (...) Postsynaptic membranes are continuously being depolarized by the quantally released neurotransmitter molecules arriving from their presynaptic terminals. In this context, an incidental lateral activation of the postsynaptic membrane is expected to induce a semblance (cellular hallucination of arrival of activity from its presynaptic terminal, which forms a unit for internal sensation) of the arrival of activity from its presynaptic terminal as a systems property. This restricts induction of semblance to a context of a very high ratio of the duration of the default state of neurotransmitter-induced postsynaptic depolarization to the total duration of incidental lateral activations of the postsynaptic membrane. This requirement spans within a time-bin of a few sleep-wake cycles. Since the duration of quantal release remains maximized, the above requirement can be achieved only by ceiling the total duration of incidental lateral activations of the postsynaptic membrane, which necessitates a state of sleep.

In this paper I analyze the theory of legitimacy at the core of John Rawls’ political liberalism. Rawls argues that a political system is well grounded when it is stable. This notion of stability embodies both pragmatic and moral elements, each of which constitutes a key desideratum of Rawlsian liberal legitimacy. But those desiderata are in tension with each other. My main claim is that Rawls’ strategy to overcome that tension through his theory of public justification is ultimately unsuccessful, because (...) the account of consensus it envisages is unstably placed between the extremes of moralized redundancy and pragmatic free-for-all. In other words, what counts as consensus is either regulated too tightly, or not enough. -/- . (shrink)

The first section of this paper asks why the notion of consensus has recently come to the fore in the medical humanities, and suggests that the answer is a function of growing technological and professional complexity. The next two sections examine the concept of consensus analytically, citing some of the recent philosophical literature. The fourth section looks at committee deliberations and their desirable outcomes, and questions the degree to which consensus serves those outcomes. In the fifth and (...) last section it is suggested that if I am to subscribe to a consensual outcome responsibly I must be personally committed to it, and that this requires a form of knowledge I call ‘fiduciary’, in this case knowledge of the competence and trustworthiness of other participants in deliberation whose expertise may have influenced my agreement.

“Meer dan in enige andere periode in de geschiedenis geniet ‘ethiek’ allerwege belangstelling” (p. 7), zo luidt de openingszin van het Handboek gezondheidsethiek (De Beaufort en Dupuis 1988). Discussies in de media lijken deze indruk te bevestigen. Wanneer de interesse van filosofische lezers door dergelijke mediaberichten worden gewekt, kunnen daar tenminste twee redenen voor zijn. Om te beginnen kunnen zij zich geroepen voelen positie te kiezen in het betreffende debat, door voor een bepaald standpunt te opteren en dat met redenen (...) te omkleden. Dat wil zeggen, zij kunnen het als hun opgave beschouwen om, vanuit hun specifieke ethische deskundigheid, de betrokkenen te assisteren door overwegingen naar voren te brengen, aspecten nader te belichten of op tegenspraken te wijzen. Een andere mogelijkheid is dat zij het debat van een wat grotere afstand volgen, door niet de onderhavige problematiek, maar veeleer het debat als zodanig tot voorwerp van onderzoek te maken. Hun interesse, verwondering of irritatie betreft dan niet zozeer de standpunten die door de betrokkenen worden verwoord, maar veeleer het idioom waarin zij hun morele afwegingen articuleren en de vooronderstellingen die ze daarbij hanteren. In deze studie wordt voor de laatste mogelijkheid gekozen. In de gangbare terminologie wordt de eerste mogelijkheid als ‘ethisch’, de tweede mogelijkheid als ‘meta- ethisch’ aangeduid. In de loop van deze studie zal echter naar voren komen dat dit onderscheid inadequaat is. Mijn meta-ethische reflectie op de problematiek van consensusvorming in de gezondheidsethiek, heeft wel degelijk ook een ethische inzet. Deze zal echter eerder ‘fundamenteel-ethisch’ dan ‘toegepast-ethisch’ van karakter zijn. De studie behelst een fundamenteel-ethische doordenking van een problematiek die naar voren komt in een toegepast- ethisch discours: de gezondheidsethiek. (shrink)

The objective of the research was to check whether False Consensus Effect (FCE), shown in much research,is also valid for ontological decisions. Test participants, faced with an ontological dilemma, made a choice three times,which of the 3 item set (Cracow City, Me myself, the Universe) refers to something most real. The research conducted first among psychology students (N=116), then replicated on mathematics students (N=126) and middle-aged people (N=106). Results: 1) All groups chose the Universe most seldom (4%-11% subjects), the (...) remaining two “objects” were chosen with similar frequency, 2) FCE occurred in all groups and in reference to each choice, 3) with people who made inconsequent choices (16% of test participants), FCE was notably higher (p <.001) in comparison to people making consequent choices,4)FCE with inconsequent people turned out to be higher (p <.01) even in comparison with “the smallest minority”, people who (consequently) chose the Universe.

The Internet of Things (IoT) infrastructure forms a gigantic network of interconnected and interacting devices. This infrastructure involves a new generation of service delivery models, more advanced data management and policy schemes, sophisticated data analytics tools, and effective decision making applications. IoT technology brings automation to a new level wherein nodes can communicate and make autonomous decisions in the absence of human interventions. IoT enabled solutions generate and process enormous volumes of heterogeneous data exchanged among billions of nodes. This results (...) in Big Data congestion, data management, storage issues and various inefficiencies. Fog Computing aims at solving the issues with data management as it includes intelligent computational components and storage closer to the data sources. Often, an IoT-enabled infrastructure is shared among many users with various requirements. Sharing resources, sharing operational costs and collective decision making (consensus) among many stakeholders is frequently neglected. This research addresses an essential requirement for adaptive, autonomous and consensus-based Fog computational solutions which are able to support distributed and in-network schemes and policies. These network schemes and policies need to meet the requirements of many users. In this work, innovative consensus-based computational solutions are investigated. These proposed solutions aim to correlate and organise data for effective management and decision making in Fog. Instead of individual decision making, the algorithms aim to aggregate several decisions into a consensus decision representing a collective agreement, benefiting from the individuals variant knowledge and meeting multiple stakeholders requirements. In order to validate the proposed solutions, hybrid research methodology is involved that includes the design of a test-bed and the execution of several experiments. In order to investigate the effectiveness of the paradigm, three experiments were designed and validated. Real-life sensor data and synthetic statistical data was collected, processed and analysed. Bayesian Machine Learning models and Analytics were used to consolidate the design and evaluate the performance of the algorithms. In the Fog environment, the first scenario tests the Aggregation by Distribution algorithm. The solution contribute in achieving a notable efficiency of data delivery obtained with a minimal loss in precision. The second scenario validates the merits of the approach in predicting the activities of high mobility IoT applications. The third scenario tests the applications related to smart home IoT. All proposed Consensus algorithms use statistical analysis to support effective decision making in Fog and enable data aggregation for optimal storage, data transmission, processing and analytics. The final results of all experiments showed that all the implemented consensus approaches surpass the individual ones in different performance terms. Formal results also showed that the paradigm is a good fit in many IoT environments and can be suitable for different scenarios when applying data analysis to correlate data with the design. Finally, the design demonstrates that Fog Computing can compete with Cloud Computing in terms of accuracy with an added preference of locality. (shrink)

It is plausible to suppose that the normativity of evaluative (e.g., moral and epistemic) judgments arises out of and is, in some sense, dependent on our actual evaluative practice. At the same time, though, it seems likely that the correctness of evaluative judgments is not merely a matter of what the underlying practice endorses and condemns; denial of this leads one into a rather objectionable form of relativism. In this paper, I will explore a social practice account of normativity according (...) to which normativity is grounded in our actual social practice of evaluation. I will show how this account allows normativity to be dependent on our actual evaluative practice, while allowing the correctness of evaluative judgments to be independent of this practice in important ways, and how the resulting temporal logic of reasons gives us a conception of morality and other sorts of evaluative discourse that is not historically local.

Verbal disputes are often seen as closely related to a lack of substantivity. However, a systematic and comprehensive investigation of how verbalness relates to substantivity is still missing. The present paper attempts to close this gap. In addition to offering different conceptions of verbalness, the paper further develops Sider’s (Writing the Book of the World, OUP, Oxford, 2011) notion of substantivity. Ultimately, I argue for a more careful choice of terminology when it comes to assessing a dispute as “(merely) verbal” (...) or “nonsubstantive”. While the paper shows that there is no strict logical relation between mere verbalness and nonsubstantivity construed along the lines set out by Sider, it also demonstrates that further notable notions of (mere) verbalness and substantivity are in fact closely intertwined.

The contemporary agonist thinker, Chantal Mouffe argues that conflicts are constitutive of politics. However, this position raises the question that concerns the survival of order and the proper types of conflicts in democracies. Although Mouffe is not consensus-oriented, consensus plays a role in her theory when the democratic order is at stake. This suggests that there is a theoretical terrain between the opposing poles of conflict and consensus. This can be discussed with the help of concepts and (...) theories that seem to be standing between the two, namely compromise, debate and the borders of democracy. I will argue that we can reveal this position with the theoretical analysis of compromise in the works of F. R. Ankersmit on the historical origin of representative democracy, and Amy Gutmann and Dennis Thompson on the role of compromise in divided communities. J. S. Mill’s view of colliding opinions offers a moderate agonistic understanding of politics, while the concept of debate plays a similar role for Márton Szabó, a contemporary Hungarian political theorist. Finally, Mouffe’s position stands at the conflictual end of this spectrum, although conflicts are delimited on the normative ground of democracy. (shrink)

It is often suggested that disagreement among scientific experts is a reason not to trust those experts, even about matters on which they are in agreement. In direct opposition to this view, I argue here that the very fact that there is disagreement among experts on a given issue provides a positive reason for non-experts to trust that the experts really are justified in their attitudes towards consensus theories. I show how this line of thought can be spelled out (...) in three distinct frameworks for non-deductive reasoning: namely, Bayesian Confirmation Theory, Inference to the Best Explanation, and Inferential Robustness Analysis.

This paper addresses the stalemate on the question whether biodiversity has intrinsic value. I distinguish between a “weak” conception and two “strong” conceptions of intrinsic value in the environmental ethics literature. The strong conceptions of intrinsic value are connected, respectively, to moral standing and to a strongly objectivist account of value. Neither of these forms of value likely applies to biodiversity. However, the weak conception of intrinsic value is neutral about both moral standing and the nature of value and plausibly (...) applies to biodiversity. In addition, weak intrinsic value avoids common objections to the claim that biodiversity is intrinsically valuable. I develop a cumulative argument showing that environmentalists should presume that biodiversity has intrinsic value in the weak sense. (shrink)
