Evolutionary debunking arguments are arguments that appeal to the evolutionary origins of evaluative beliefs to undermine their justification. This paper aims to clarify the premises and presuppositions of EDAs—a form of argument that is increasingly put to use in normative ethics. I argue that such arguments face serious obstacles. It is often overlooked, for example, that they presuppose the truth of metaethical objectivism. More importantly, even if objectivism is assumed, the use of EDAs in normative ethics is incompatible with a (...) parallel and more sweeping global evolutionary debunking argument that has been discussed in recent metaethics. After examining several ways of responding to this global debunking argument, I end by arguing that even if we could resist it, this would still not rehabilitate the current targeted use of EDAs in normative ethics given that, if EDAs work at all, they will in any case lead to a truly radical revision of our evaluative outlook.

The possibility that nothing really matters can cause much anxiety, but what would it mean for that to be true? Since it couldn’t be bad that nothing matters, fearing nihilism makes little sense. However, the consequences of belief in nihilism will be far more dramatic than often thought. Many metaethicists assume that even if nothing matters, we should, and would, go on more or less as before. But if nihilism is true in an unqualified way, it can’t be the case (...) that we should go on as before. And given some plausible assumptions about our psychology, it’s also unlikely that we would go on as before: belief in nihilism will lead to loss of evaluative belief, and that will lead to loss or deflation of our corresponding subjective concerns. Now if nothing matters, then this consequence also wouldn’t matter. But this consequence will be extremely harmful if we believe in nihilism but things do matter, an asymmetry that gives us, in Pascalian fashion, pragmatic reasons not to believe in nihilism, and reasons not to try to find out whether it is really true.

Some disability activists argue that disability is merely a difference. It is often objected that this view has unacceptable implications, implying, for example, that it is permissible to cause disability. In reply, Elizabeth Barnes argues that viewing disability as a difference needn’t entail such implications and that seeing such implications as unacceptable is question-begging. We argue that Barnes misconstrues this objection to the mere difference view of disability: it’s not question-begging to regard its implications as unacceptable, and the grounds that (...) Barnes offers for potentially blocking some of these implications fail to explain our conviction that it’s impermissible to cause disability. (shrink)

The concept of well-being is one of the oldest and most important topics in philosophy and ethics, going back to ancient Greek philosophy and Aristotle. Following the boom in happiness studies in the last few years it has moved to centre stage, grabbing media headlines and the attention of scientists, psychologists and economists. Yet little is actually known about well-being and it is an idea often poorly articulated. The Routledge Handbook of Philosophy of Well-Being provides a comprehensive, outstanding guide and (...) reference source to the key topics and debates in this exciting subject. Comprising over forty chapters by a team of international contributors, the Handbook is divided into six parts: well-being in the history of philosophy current theories of well-being, including hedonism, and perfectionism examples of well-being and its opposites, including friendship and virtue and pain and death theoretical issues such as well-being and value, harm, identity and well-being and children well-being in moral and political philosophy well-being and related subjects including law, economics, and medicine. Essential reading for students and researchers in ethics and political philosophy, it will also be an invaluable resource for those in related disciplines such as psychology, politics and sociology.

Neuroimaging studies on moral decision-making have thus far largely focused on differences between moral judgments with opposing utilitarian (well-being maximizing) and deontological (duty-based) content. However, these studies have investigated moral dilemmas involving extreme situations, and did not control for two distinct dimensions of moral judgment: whether or not it is intuitive (immediately compelling to most people) and whether it is utilitarian or deontological in content. By contrasting dilemmas where utilitarian judgments are counterintuitive with dilemmas in which they are intuitive, we (...) were able to use functional magnetic resonance imaging to identify the neural correlates of intuitive and counterintuitive judgments across a range of moral situations. Irrespective of content (utilitarian/deontological), counterintuitive moral judgments were associated with greater difficulty and with activation in the rostral anterior cingulate cortex, suggesting that such judgments may involve emotional conflict; intuitive judgments were linked to activation in the visual and premotor cortex. In addition, we obtained evidence that neural differences in moral judgment in such dilemmas are largely due to whether they are intuitive and not, as previously assumed, to differences between utilitarian and deontological judgments. Our findings therefore do not support theories that have generally associated utilitarian and deontological judgments with distinct neural systems. (shrink)

Neuroscience and psychology have recently turned their attention to the study of the subpersonal underpinnings of moral judgment. In this article we critically examine an influential strand of research originating in Greene's neuroimaging studies of ‘utilitarian’ and ‘non-utilitarian’ moral judgement. We argue that given that the explananda of this research are specific personal-level states—moral judgments with certain propositional contents—its methodology has to be sensitive to criteria for ascribing states with such contents to subjects. We argue that current research has often (...) failed to meet this constraint by failing to correctly ‘fix’ key aspects of moral judgment, criticism we support by detailed examples from the scientific literature.

Whether God exists is a metaphysical question. But there is also a neglected evaluative question about God’s existence: Should we want God to exist? Very many, including many atheists and agnostics, appear to think we should. Theists claim that if God didn’t exist things would be far worse, and many atheists agree; they regret God’s inexistence. Some remarks by Thomas Nagel suggest an opposing view: that we should want God not to exist. I call this view anti-theism. I explain how (...) such view can be coherent, and why it might be correct. Anti-theism must be distinguished from the argument from evil or the denial of God’s goodness; it is a claim about the goodness of God’s existence. Anti-theists must claim that it’s a logical consequence of God’s existence that things are worse in certain respects. The problem is that God’s existence would also make things better in many ways. Given that God’s existence is likely to be impersonally better overall, anti-theists face a challenge similar to that facing nonconsequentialists. I explore two ways of meeting this challenge.

The universe that surrounds us is vast, and we are so very small. When we reflect on the vastness of the universe, our humdrum cosmic location, and the inevitable future demise of humanity, our lives can seem utterly insignificant. Many philosophers assume that such worries about our significance reflect a banal metaethical confusion. They dismiss the very idea of cosmic significance. This, I argue, is a mistake. Worries about cosmic insignificance do not express metaethical worries about objectivity or nihilism, and (...) we can make good sense of the idea of cosmic significance and its absence. It is also possible to explain why the vastness of the universe can make us feel insignificant. This impression does turn out to be mistaken, but not for the reasons typically assumed. In fact, we might be of immense cosmic significance—though we cannot, at this point, tell whether this is the case. (shrink)

According to Joshua Greene’s influential dual process model of moral judgment, different modes of processing are associated with distinct moral outputs: automatic processing with deontological judgment, and controlled processing with utilitarian judgment. This paper aims to clarify and assess Greene’s model. I argue that the proposed tie between process and content is based on a misinterpretation of the evidence, and that the supposed evidence for controlled processing in utilitarian judgment is actually likely to reflect generic deliberation which, ironically, is incompatible (...) with a utilitarian outlook. This alternative proposal is further supported by the results of a recent neuroimaging study we have done. (shrink)

In 1907, Alfred Stieglitz took what was to become one of his signature photographs, The Steerage. Stieglitz stood at the rear of the ocean liner Kaiser Wilhelm II and photographed the decks, first-class passengers above and steerage passengers below, carefully exposing the film to their reflected light. Later, in the darkroom, Stieglitz developed this film and made a number of prints from the resulting negative. The photograph is a familiar one, an enduring piece of social commentary, but what exactly is (...) The Steerage which Stieglitz has given us? It is clearer what The Steerage is not. It is distinct from each of its prints and from its negative. These may be dusty or torn without The Steerage being so, and any one of these could be destroyed without thereby destroying The Steerage itself. Nor is The Steerage the set of its prints. The set could not have had different members, while The Steerage could have had more, fewer, or different prints.1 Similar reasoning rules out the mereological sum of parts of its actual prints, for The Steerage’s prints might not have comprised just these parts. We are left with a puzzle, what sort of thing is a photograph? This puzzle is not unique to photography. Similar reasoning generates an analogous puzzle for any repeatable work of art. Novels, poems, plays, symphonies, songs, and the rest share an ontological predicament and create a 1 general puzzle concerning the ontological status of repeatable works of art. It is widely held that the puzzle has an equally general solution, one which I will argue fails for systematic reasons. Although my target here is the supposed solution to the general problem, photography will remain the central case under scrutiny. I offer it as a model for our thinking about the wider class in order to reap the benefits of thinking in terms of concrete cases. Although this risks a trade-off with the generality of my conclusions—there are important differences of detail between the cases—I hope it is clear that the considerations I appeal to in photography are not idiosyncratic but shared by the wider class..

Katarzyna de Lazari-Radek and Peter Singer argue that evolutionary considerations can resolve Sidgwick’s dualism of practical reason because such considerations debunk moral views that give weight to self-interested or partial considerations but cannot threaten the principle of universal benevolence. I argue that even if we grant these claims, this appeal to evolution is ultimately self-defeating. De Lazari-Radek and Singer face a dilemma. Either their evolutionary argument against partial morality succeeds, but then we need to also give up our conviction that (...) suffering is bad; or there is a way to defend this conviction, but then their argument against partiality fails. Utilitarians, I suggest, should resist the temptation to appeal to evolutionary debunking arguments. (shrink)

Robert Nozick famously raised the possibility that there is a sense in which both deontology and utilitarianism are true: deontology applies to humans while utilitarianism applies to animals. In recent years, there has been increasing interest in such a hybrid views of ethics. Discussions of this Nozickian Hybrid View, and similar approaches to animal ethics, often assume that such an approach reflects the commonsense view, and best captures common moral intuitions. However, recent psychological work challenges this empirical assumption. We review (...) evidence suggesting that the folk is deontological all the way down—it is just that the moral side constraints that protect animals from harm are much weaker than those that protect humans. In fact, it appears that people even attribute some deontological protections, albeit extremely weak ones, to inanimate objects. We call this view Multi-level Weighted Deontology. While such empirical findings cannot show that the Nozickian Hybrid View is false, or that it is unjustified, they do remove its core intuitive support. That support belongs to Multi-level Weighted Deontology, a view that is also in line with the view that Nozick himself seemed to favour. To complicate things, however, we also review evidence that our intuitions about the moral status of humans are, at least in significant part, shaped by factors relating to mere species membership that seem morally irrelevant. We end by considering the potential debunking upshot of such findings about the sources of common moral intuitions about the moral status of animals. (shrink)

Ethical theory often starts with our intuitions about particular cases and tries to uncover the principles that are implicit in them; work on the ‘trolley problem’ is a paradigmatic example of this approach. But ethicists are no longer the only ones chasing trolleys. In recent years, psychologists and neuroscientists have also turned to study our moral intuitions and what underlies them. The relation between these two inquiries, which investigate similar examples and intuitions, and sometimes produce parallel results, is puzzling. Does (...) it matter to ethics whether its armchair conclusions match the psychologists’ findings? I argue that reflection on this question exposes psychological presuppositions implicit in armchair ethical theorising. When these presuppositions are made explicit, it becomes clear that empirical evidence can (and should) play a positive role in ethical theorising. Unlike recent assaults on the armchair, the argument I develop is not driven by a naturalist agenda, or meant to cast doubt on the reliability of our moral intuitions; on the contrary, it is even compatible with non-naturalism, and takes the reliability of intuition as its premise. The argument is rather that if our moral intuitions are reliable, then psychological evidence should play a surprisingly significant role in the justification of moral principles. (shrink)

Research into moral decision-making has been dominated by sacrificial dilemmas where, in order to save several lives, it is necessary to sacrifice the life of another person. It is widely assumed that these dilemmas draw a sharp contrast between utilitarian and deontological approaches to morality, and thereby enable us to study the psychological and neural basis of utilitarian judgment. However, it has been previously shown that some sacrificial dilemmas fail to present a genuine contrast between utilitarian and deontological options. Here, (...) I raise deeper problems for this research paradigm. Even when sacrificial dilemmas present a contrast between utilitarian and deontological options at a philosophical level, it is misleading to interpret the responses of ordinary folk in these terms. What is currently classified as “utilitarian judgment” does not in fact share essential features of a genuine utilitarian outlook, and is better explained in terms of commonsensical moral notions. When subjects deliberate about such dilemmas, they are not deciding between opposing utilitarian and deontological solutions, but engaging in a richer process of weighing opposing moral reasons. Sacrificial dilemmas therefore tell us little about utilitarian decision-making. An alternative approach to studying proto-utilitarian tendencies in everyday moral thinking is proposed. (shrink)

This article draws attention to several common mistakes in thinking about biomedical enhancement, mistakes that are made even by some supporters of enhancement. We illustrate these mistakes by examining objections that John Harris has recently raised against the use of pharmacological interventions to directly modulate moral decision-making. We then apply these lessons to other influential figures in the debate about enhancement. One upshot of our argument is that many considerations presented as powerful objections to enhancement are really strong considerations in (...) favour of biomedical enhancement, just in a different direction. Another upshot is that it is unfortunate that much of the current debate focuses on interventions that will radically transform normal human capacities. Such interventions are unlikely to be available in the near future, and may not even be feasible. But our argument shows that the enhancement project can still have a radical impact on human life even if biomedical enhancement operated entirely within the normal human range. (shrink)

It is widely held that it is only contingent that the sensation of pain is disliked, and that when pain is not disliked, it is not intrinsically bad. This conjunction of claims has often been taken to support a subjectivist view of pain’s badness on which pain is bad simply because it is the object of a negative attitude and not because of what it feels like. In this paper, I argue that accepting this conjunction of claims does not commit (...) us to this subjectivist view. They are compatible with an objectivist view of pain’s badness, and with thinking that this badness is due to its phenomenal quality. Indeed, I argue that once the full range of options is in view, the most plausible account of pain is incompatible with subjectivism about value. (shrink)

This paper examines implicaturist hybrid theories by examining how closely attitude expression by moral utterances fits with the varieties of implicature (conventional, particular conversational, generalized conversational) using five standard criteria for implicature: indeterminacy (§3), reinforceability (§4), non-detachability (§5), cancellability (§6), and calculability (§7). I argue (1) that conventional implicature is a clear non-starter as a model of attitude expression by moral utterances (2) that generalised conversational implicature yields the most plausible implicaturist hybrid but (3) that a non-implicaturist, and non-hybrid, alternative (...) might in fact be superior.

Many believe that severe intellectual impairment, blindness or dying young amount to serious harm and disadvantage. It is also increasingly denied that it matters, from a moral point of view, whether something is biologically normal to humans. We show that these two claims are in serious tension. It is hard explain how, if we do not ascribe some deep moral significance to human nature or biological normality, we could distinguish severe intellectual impairment or blindness from the vast list of seemingly (...) innocent ways in which we fail to have as much wellbeing as we could, such not having super-intelligence, or not living to 130. We consider a range of attempts to draw this intuitive normative distinction without appealing to normality. These, we argue, all fail. But this doesn't mean that we cannot draw this distinction or that we must, implausibly, conclude that biological normality does possess an inherent moral importance. We argue that, despite appearances, it is not biological normality but rather statistical normality that, although lacking any intrinsic moral significance, nevertheless makes an important moral difference in ways that explain and largely justify the intuitive distinction.

While all agree that score compliance in performance is valuable, the source of this value is unclear. Questions about what authenticity requires crowd out questions about our reasons to be compliant in the first place, perhaps because they seem trivial or uninteresting. I argue that such reasons cannot be understood as ordinary aesthetic, instrumental, epistemic, or moral reasons. Instead, we treat considerations of score compliance as having a kind of final value, one which requires further explanation. Taking as a model (...) the Humean account of fidelity as an artificial virtue, I sketch a practice-theoretic account of the nature and source of such reasons, one on which we can say that they are, after all, aesthetic, but only indirectly so.

Saul Kripke has claimed that there are necessary connections between material things and their material origins. The usual defences of such necessity of origin theses appeal to either a sufficiency of origin principle or a branching-times model of necessity. In this paper we offer a different defence. Our argument proceeds from more modest ‘independence principles’, which govern the processes by which material objects are produced. Independence principles are motivated, in turn, by appeal to a plausible metaphysical principle governing such processes, (...) their invulnerability to non-local prevention. We outline the new argument, and distinguish it from both of the usual defences. (shrink)

The hypothermia experiments performed on humans during the Second World War at the German concentration camp in Dachau have been regarded as crimes against humanity, disguised as medical research. For almost 50 years, scientists maintained that the study produced valuable, even if not totally reliable, information. In recent years, the results from the Dachau hypothermia project were glamorized with life-saving potential and a heated ethical dialogue was activated about the use of life-saving but tainted scientific information. In the wake of (...) the debate, an in-depth examination of the scientific rigour of the project was performed and revealed that neither the science nor the scientists from Dachau could be trusted and that the data were worthless. The body of medical opinion accepted the unfavourable determination but a few scientists and ethicists have continued to endorse the validity, of at least parts, of the Dachau hypothermia data. The conduct of the scientific communications about the Dachau hypothermia experiments by the scientific and ethical communities invites serious consideration of a possible ethical misadventure. It appears that for almost 50 years, the results of the study had been endorsed without careful examination of the scientific base of the experiments and that secondary citation of relevant original material may have been commonly employed. These infractions contributed to a myth that good science was practised by the Nazis at Dachau. The more recent emphasis on the life-saving potential of the Dachau data, without citation of credible supporting evidence, has also been misleading. Similarly, acceptance of a determination by an in-depth examination that the 'whole' Dachau project if flawed with simultaneous endorsement of the validity of 'parts' of the results, poses an ethical problem. It is advisable that before seeking ethical consultation about the use of unethically obtained data, scientists should examine the quality of science behind the controversial information and ethicists should verify the integrity of the material prior to engaging in a dialogue.

Much seems to be at stake in metaphysical questions about, for example, God, free will or morality. One thing that could be at stake is the value of the universe we inhabit—how good or bad it is. We can think of competing philosophical positions as describing possibilities, ways the world might turn out to be, and to which value can be assigned. When, for example, people hope that God exists, or fear that we do not possess free will, they express (...) attitudes towards these possibilities, attitudes that presuppose answers to questions about their comparative value. My aim in this paper is to distinguish these evaluative questions from related questions with which they can be confused, to identify structural constraints on their proper pursuit, and to address objections to their very coherence. Answers to such evaluative questions offer one measure of the importance of philosophical disputes. (shrink)

Mackie drew attention to the distinct semantic and metaphysical claims made by metaethical realists, arguing that although our evaluative discourse is cognitive and objective, there are no objective evaluative facts. This distinction, however, also opens up a reverse possibility: that our evaluative discourse is antirealist, yet objective values do exist. I suggest that this seemingly farfetched possibility merits serious attention; realism seems committed to its intelligibility, and, despite appearances, it isn‘t incoherent, ineffable, inherently implausible or impossible to defend. I argue (...) that reflection on this possibility should lead us to revise our understanding of the debate between realists and antirealists. It is not only that the realist‘s semantic claim is insufficient for realism to be true, as Mackie argued; it‘s not even necessary. Robust metaethical realism is best understood as making a purely metaphysical claim. It is thus not enough for antirealists to show that our discourse is antirealist. They must directly attack the realist‘s metaphysical claim. (shrink)

ABSTRACTThe new paradigm in the psychology of reasoning redirects the investigation of deduction conceptually and methodologically because the premises and the conclusion of the inferences are assumed to be uncertain. A probabilistic counterpart of the concept of logical validity and a method to assess whether individuals comply with it must be defined. Conceptually, we used de Finetti's coherence as a normative framework to assess individuals' performance. Methodologically, we presented inference schemas whose premises had various levels of probability that contained non-numerical (...) expressions and, as a control, sure levels. Depending on the inference schemas, from 60% to 80% of the participants produced coherent conclusions when the premises were uncertain. The data also show that except for schemas involving conjunction, performance was consistently lower with certain than uncertain premises, the rate of conjunction fallacy was consistently low (not exceeding 20%,..

This chapter focuses on the responses that proponents of virtue epistemology (VE) make to radical skepticism and particularly to two related forms of it, Pyrrhonian skepticism and the “underdetermination-based” argument, both of which have been receiving widening attention in recent debate. Section 1 of the chapter briefly articulates these two skeptical arguments and their interrelationship, while section 2 explains the close connection between a virtue-theoretic and a neo-Moorean response to them. In sections 3 and 4 I advance arguments for improving (...) the prospects of virtue-theoretic responses, sketching a particular version of VE that by recasting somewhat how we understand the “externalist turn in epistemology” also suggests ways of improving the adequacy of philosophical diagnoses and responses to skepticism.

Several authors have suggested that we cannot fully grapple with the ethics of human enhancement unless we address neglected questions about our place in the world, questions that verge on theology but can be pursued independently of religion. A prominent example is Michael Sandel, who argues that the deepest objection to enhancement is that it expresses a Promethean drive to mastery which deprives us of openness to the unbidden and leaves us with nothing to affirm outside our own wills. Sandel's (...) argument against enhancement has been criticized, but his claims about mastery and the unbidden, and their relation to religion, have not yet received sufficient attention. I argue that Sandel misunderstands the notions of mastery and the unbidden and their significance. Once these notions are properly understood, they have surprising implications. It turns out that the value of openness to the unbidden is not just independent of theism, as Sandel claims, but is in fact not even fully compatible with it. But in any case that value cannot support Sandel's objection to enhancement. This is because it is not enhancement but certain forms of opposition to enhancement that are most likely to express a pernicious drive to mastery. (shrink)

We live in times where it is possible to control our emotions using biomedical means – for example by taking pills that make us feel better. This chapter discusses one worry about the biomedical enhancement of mood. It is a worry that seems to play an important role in more familiar objections to biomedical enhancement of mood, such as the objection that it would lead to inauthenticity. The worry is that the use of positive mood enhancers will corrupt emotional lives. (...) Ethical questions about the biomedical enhancement of mood are often really questions about our affective reasons. Negative emotions typically feel bad, positive ones typically feel good. Here our hedonic reasons come into direct competition with affective reasons. Those who entirely dismiss affective reasons, or at least think that negative affective reasons are extremely weak, are likely to see little problem with positive mood enhancers. (shrink)

A New Route to the Necessity of Origin’ (2004, henceforth ‘NR’), we offered an argument for the thesis that there are necessary connections between material things and their material origins. Much of the philosophical interest lay in our claim that the argument did not depend on so-called sufficiency principles for crossworld identity. It has been the verdict of much recent work on the necessity of origin that valid arguments for the thesis require some such sufficiency principle as a premise but (...) that such principles are deeply problematic.1 Finding an argument free of such principles would advance both our understanding and the plausibility of that thesis. These claims are now the subject of a pair of insightful critiques by Teresa Robertson and Graeme Forbes (2006, henceforth ‘RF’) and by Ross Cameron and Sonia Roca (2006, henceforth ‘CR’), and we welcome the opportunity to clarify and improve our account of the matter.

The appealing idea that knowledge is best understood as a kind of achievement faces significant criticisms, among them Matthew Chrisman’s charge that the whole project rests on a kind of ontological category mistake. Chrisman argues that while knowledge and belief are states, the kind of normativity found in, for example, Sosa’s famous ‘Triple-A’ structure of assessment is only applicable to performances, end-directed events that unfold over time, and never to states. What is overlooked, both by Chrisman and those he criticizes, (...) is a whole range of projects, those like friendship, health, marriage, and sobriety, where the end is not distinct from our pursuit of it. I suggest that such ‘inner projects’ are in fact stative achievements and thus provide a different sort of model for thinking about knowledge as an achievement. Reconceiving the project along these lines also helps to solve another outstanding problem, the charge that being an achievement is not necessary for knowledge because some knowledge, especially testimonial knowledge, is come by with little or no effort.

When is an artwork complete? Most hold that the correct answer to this question is psychological in nature. A work is said to be complete just in case the artist regards it as complete or is appropriately disposed to act as if he or she did. Even though this view seems strongly supported by metaphysical, epistemological, and normative considerations, this article argues that such psychologism about completeness is mistaken, fundamentally, because it cannot make sense of the artist's own perspective on (...) his or her work. For the artist, the question is not about his or her own psychology, but about the character of the work and the context in which he or she works. A nonpsychological account of completeness, on which completeness is a question of whether the work satisfies the conditions implicit in the artist's plan, avoids this problem and is equally or better able to explain the metaphysical, epistemic, and normative phenomena which appeared to support psychologism.

Could a work of art actually authored by one artist have been authored, instead, by another? This is the question of the necessity of authorship. After distinguishing this question from another, regarding individuation, with which it is often confused, this paper offers an argument that authorship is indeed a necessary feature of most artworks. The argument proceeds from ‘independence principles’, which govern the processes by which artworks are produced. Independence principles are motivated, in turn, by metaphysical reflections on what it (...) takes to prevent an artist from producing a particular work of art. (shrink)

This paper describes a cubic water tank equipped with a movable partition receiving various amounts of liquid used to represent joint probability distributions. This device is applied to the investigation of deductive inferences under uncertainty. The analogy is exploited to determine by qualitative reasoning the limits in probability of the conclusion of twenty basic deductive arguments (such as Modus Ponens, And-introduction, Contraposition, etc.) often used as benchmark problems by the various theoretical approaches to reasoning under uncertainty. The probability bounds imposed (...) by the premises on the conclusion are derived on the basis of a few trivial principles such as "a part of the tank cannot contain more liquid than its capacity allows", or "if a part is empty, the other part contains all the liquid". This stems from the equivalence between the physical constraints imposed by the capacity of the tank and its subdivisions on the volumes of liquid, and the axioms and rules of probability. The device materializes de Finetti's coherence approach to probability. It also suggests a physical counterpart of Dutch book arguments to assess individuals' rationality in probability judgments in the sense that individuals whose degrees of belief in a conclusion are out of the bounds of coherence intervals would commit themselves to executing physically impossible tasks.

Although most people believe that it is morally wrong to intentionally create children who have an impairment, it is widely held that we cannot criticize such procreative choices unless we find a solution to Parfit’s non-identity problem. I argue that we can. Jonathan Glover has recently argued that, in certain circumstances, such choices would be self-defeating even if morally permissible. I argue that although the scope of Glover’s argument is too limited, it nevertheless directs attention to a moral defect in (...) the attitudes that could motivate such procreative choices, attitudes that, properly characterized, turn out to be person-affecting in character. I conclude by arguing that prospective parents who want to create a child with an impairment face a dilemma. If they want to avoid the charge that their aim is morally defective, they must deny that the desired impairment is harmful. But this would commit them to endorsing the controversial claim that it is morally permissible or even required to turn normal children into impaired ones. (shrink)

When a new piece of information contradicts a currently held belief, one has to modify the set of beliefs in order to restore its consistency. In the case where it is necessary to give up a belief, some of them are less likely to be abandoned than others. The concept of epistemic entrenchment is used by some AI approaches to explain this fact based on formal properties of the belief set (e.g., transitivity). Two experiments were designed to test the hypothesis (...) that contrary to such views, (i) belief is naturally represented by degrees rather than in an all-or-nothing manner, (ii) entrenchment is primarily a matter of content and not only a matter of form, and (iii) consequently prior degree of belief is a powerful factor of change. The two experiments used Elio and Pelletier's (1997) paradigm in which participants were presented with full simple deductive arguments whose conclusion was denied, following which they were asked to decide which premise to revise.
