In this article, we defend pairwise comparison as a method to resolve conflicting claims from different people that cannot be jointly satisfied because of a scarcity of resources. We consider Michael Otsuka's recent challenge that pairwise comparison leads to intransitive choices for the (someone who believes the numbers should not count in forced choices among lives) and Frances Kamm's responses to Otsuka's challenge. We argue that Kamm's responses do not succeed, but that the threat they are designed to (...) meet is illusory. Once the method of pairwise comparison is understood in a manner consistent with its proposed use, the challenge disappears. In making this argument, we examine questions about the interpretation of pairwise comparison and maintain that it must be understood as a method for ensuring that decisions are justifiable from the perspective of each affected individual.

We contrast three decision rules that extend Expected Utility to contexts where a convex set of probabilities is used to depict uncertainty: Γ-Maximin, Maximality, and E-admissibility. The rules extend Expected Utility theory as they require that an option is inadmissible if there is another that carries greater expected utility for each probability in a (closed) convex set. If the convex set is a singleton, then each rule agrees with maximizing expected utility. We show that, even when the option set is (...) convex, this pairwise comparison between acts may fail to identify those acts which are Bayes for some probability in a convex set that is not closed. This limitation affects two of the decision rules but not E-admissibility, which is not a pairwise decision rule. E-admissibility can be used to distinguish between two convex sets of probabilities that intersect all the same supporting hyperplanes. (shrink)

Several liberal philosophers and penal theorists have argued that the state has a reason to prohibit acts that harm individuals. But what is harm? According to one specification of harm, a person P is harmed by an act (or an event) a iff, as a result of a, P is made worse off in terms of well-being. One central question here involves the baseline against which we assess whether someone is ‘worse off’. In other words, when a person is harmed (...) he is worse off, certainly—but what is worse off a variation from? A central part of the paper critically discusses different answers to this question based on versions of what we can call: the temporal baseline, the baseline from mankind and the counterfactual baseline. Essentially, it will be argued that the counterfactual baseline leaves us with a better understanding of harming than the other baselines discussed. The final part of the paper will describe some of the implications of our investigation for the application and evaluation of the view that harm matters in the justification of which type of acts should be criminalized by the state. The overall conclusion of the paper is that adherents of a view like the harm principle face a dilemma. Either they can accept the counterfactual baseline but then, they can do without the harm principle. Or they can reject the counterfactual baseline—but then they will have to formulate an alternative baseline which, as will be shown in the paper, is no easy task. (shrink)

Suppose you can save only one of two groups of people from harm, with one person in one group, and five persons in the other group. Are you obligated to save the greater number? While common sense seems to say ‘yes’, the numbers skeptic says ‘no’. Numbers Skepticism has been partly motivated by the anti-consequentialist thought that the goods, harms and well-being of individual people do not aggregate in any morally significant way. However, even many non-consequentialists think that Numbers (...) Skepticism goes too far in rejecting the claim that you ought to save the greater number. Besides the prima facie implausibility of Numbers Skepticism, Michael Otsuka has developed an intriguing argument against this position. Otsuka argues that Numbers Skepticism, in conjunction with an independently plausible moral principle, leads to inconsistent choices regarding what ought to be done in certain circumstances. This inconsistency in turn provides us with a good reason to reject Numbers Skepticism. Kirsten Meyer offers a notable challenge to Otsuka’s argument. I argue that Meyer’s challenge can be met, and then offer my own reasons for rejecting Otsuka’s argument. In light of these criticisms, I then develop an improved, yet structurally similar argument to Otsuka’s argument. I argue for the slightly different conclusion that the view proposed by John Taurek that ‘the numbers don’t count’ leads to inconsistent choices, which in turn provides us with a good reason to reject Taurek’s position.

BackgroundThe complexity of decision-making in the paediatric context is well recognised. In the majority of cases, parents and healthcare professionals work together to decide which treatments the paediatric patient should receive. On occasions, however, parental wishes conflict with what clinicians think is best for the paediatric patient. Where persistent disagreement between clinicians and parents exists, clinicians must ascertain if they have a moral, professional, and legal obligation to overrule the parents' decision and implement their preferred option.PurposeFew decision-making frameworks to assist (...) in addressing the ethical issues that arise in clinical decision-making relate specifically to the paediatric context. Diekema's Harm Threshold Framework and the Zone of Parental Discretion Framework assist in determining whether parental decisions should or should not be overridden. This paper examines the similarities and differences between these frameworks.MethodsThe frameworks are analysed i... (shrink)

We introduce two extreme methods to pairwisely compare ordered lists of the same length, viz. the comonotonic and the countermonotonic comparison method, and show that these methods are, respectively, related to the copula T M (the minimum operator) and the Ł ukasiewicz copula T L used to join marginal cumulative distribution functions into bivariate cumulative distribution functions. Given a collection of ordered lists of the same length, we generate by means of T M and T L two probabilistic relations Q (...) M and Q L and identify their type of transitivity. Finally, it is shown that any probabilistic relation with rational elements on a 3-dimensional space of alternatives which possesses one of these types of transitivity, can be generated by three ordered lists and at least one of the two extreme comparison methods.

Although the counterfactual comparative account of harm, according to which someone is harmed when things go worse for her than they otherwise would have, is intuitively plausible, it has recently come under attack. There are five serious objections in the literature: some philosophers argue that the counterfactual account makes it hard to see how we could harm someone in the course of benefitting that person; others argue that Parfit’s non-identity problem is particularly problematic; another objection claims that the account forces (...) us to see many harms where there is just one; a fourth objection is based on the claim that the counterfactual account makes mysterious the distinction between harms and mere failures-to-benefit; and a final problem arises from cases of pre-emption, in which the nearest possible world in which the harmful event does not occur is a world in which some other harmful event occurs. This paper argues that, properly understood, harm essentially involves a counterfactual comparison, and that these comparisons are sensitive to context in the manner typical of counterfactual conditionals, and that, augmented with two plausible distinctions, this account has the resources to provide satisfying responses to each of the objections that have been raised against it.

Much recent research has sought to uncover the neural basis of moral judgment. However, it has remained unclear whether "moral judgments" are sufficiently homogenous to be studied scientifically as a unified category. We tested this assumption by using fMRI to examine the neural correlates of moral judgments within three moral areas: (physical) harm, dishonesty, and (sexual) disgust. We found that the judgment ofmoral wrongness was subserved by distinct neural systems for each of the different moral areas and that these differences (...) were much more robust than differences in wrongness judgments within a moral area. Dishonest, disgusting, and harmful moral transgression recruited networks of brain regions associated with mentalizing, affective processing, and action understanding, respectively. Dorsal medial pFC was the only region activated by all scenarios judged to be morally wrong in comparison with neutral scenarios. However, this region was also activated by dishonest and harmful scenarios judged not to be morally wrong, suggestive of a domain-general role that is neither peculiar to nor predictive of moral decisions. These results suggest that moral judgment is not a wholly unified faculty in the human brain, but rather, instantiated in dissociable neural systems that are engaged differentially depending on the type of transgression being judged.

The present study uses cross‐cultural samples of marketing practitioners from two European Union (EU) nations (the United Kingdom and Spain) and China to examine the relationships between moral intensity, personal moral philosophies and ethical decision making. Additionally, cross‐cultural comparisons were made regarding intentions, personal moral philosophies and moral intensity. Results indicate that both samples tend to use the perceived harm construct (e.g. magnitude of consequences, probability of effect, temporal immediacy and concentration of effect) to determine intentions in situations involving (...) ethical issues. However, social consensus tends to be situation‐specific for both groups and proximity seems not to be used at all when making decisions in situations involving ethics. As for personal moral philosophies, idealism is only used by the EU sample; however, for both samples, the use of relativism depends upon the specific situation. (shrink)

Psychologists and philosophers who pose moral dilemmas to understand moral judgment typically specify outcomes as certain to occur in them. This contrasts with real-life moral decision-making, which is almost always infused with probabilities (e.g., the probability of a given outcome if an action is or is not taken). Seven studies examine sensitivity to the size and location of shifts in probabilities of outcomes that would result from action in moral dilemmas. We find that moral judgments differ between actions that result (...) in an equal increase in probability of harm (equal size), but have different end-states (e.g., an increase in harm probability from 25% to 50% or from 50% to 75%). This deviation from expected value is robust under separate evaluation, and increases when the comparison between shifts is made explicit under simultaneous evaluation. Consistent with the centrality of perceived harm in some models of moral judgment, perceived harm partially mediates sensitivity to location of harm probability shift. Unlike for shifts in harm probabilities, participants are insensitive to the location of shifts in probability of beneficial outcomes. They are also insensitive to the location of shifts in probability of analogous monetary losses and gains, suggesting an asymmetry between harm and benefit in moral reasoning, as well as an asymmetry between moral and monetary decision-making more broadly. Implications for normative philosophical theory and moral psychological theory, as well as practical applications, are discussed. (shrink)

The debates between Bayesian, frequentist, and other methodologies of statistics have tended to focus on conceptual justifications, sociological arguments, or mathematical proofs of their long run properties. Both Bayesian statistics and frequentist (“classical”) statistics have strong cases on these grounds. In this article, we instead approach the debates in the “Statistics Wars” from a largely unexplored angle: simulations of different methodologies’ performance in the short to medium run. We conducted a large number of simulations using a straightforward decision problem based (...) around tossing a coin with unknown bias and then placing bets. In this simulation, we programmed four players, inspired by Bayesian statistics, frequentist statistics, Jon Williamson’s version of Objective Bayesianism, and a player who simply extrapolates from observed frequencies to general frequencies. The last player functions as a benchmark: a statistical methodology should at least outperform a crude form of induction. We focused on the performance of these methodologies in guiding the players towards good decisions. Unlike an earlier simulation study of this type, we found no systematic difference in performance between the Bayesian and frequentist players, provided the Bayesian used a flat prior and the frequentist used a low confidence level. Unlike that study, we were able to use Big Data methods to mitigate problems of random error in the simulation results. The Williamsonian player, who is a novel element of our study, also had no systematic differences in their performance, provided that they use a low confidence level. These players performed similarly even in the very short run, when players were making different decisions. Our study indicates that all three methodologies should be taken seriously by philosophers and practitioners of statistics. However, the frequentist and Williamsonian performed poorly when their confidence levels were high, and the Bayesian was surprisingly harmed by biased priors, providing some unexpected lessons for these methodologies when facing this type of decision problem.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Enviornment 6.2 (2001) 114-118 [Access article in PDF] Book Review Child versus Childmaker: Future Persons and Present Duties in Ethics and the Law Child versus Childmaker: Future Persons and Present Duties in Ethics and the Law. Melinda A. Roberts. Lanham, Md.: Rowman & Littlefield, 1998. Pp. 235. ISBN 0-8476-8901-8 (Paperback) This book will provide the reader with a systematic examination of some of the most difficult (...) philosophical issues involved in procreation, and most notably those raised by wrongful life claims and the non-identity problem. Can an action without which a given child would not even exist be simultaneously said to harm this very child? This is the key question addressed in this book. It is relevant not only to bioethicists, but also to those concerned with the possibility of harming members of future generations in general. The author proceeds with remarkable clarity in three steps. First, she unveils the core intuition and unfolds the key implications of what is standardly referred to as the person-affecting view. Second, she focuses on the now famous non-identity problem that is supposed to raise a serious challenge to the plausibility of the person-affecting view. Third, wrongful life and human cloning are taken as illustrations of the problem.The starting point is thus the person-affecting or personalist view. The author argues that what is at stake in such a view is not only a concern for [End Page 114] persons (as opposed to plants or stones), but also for definite persons. The core intuition that "what is bad must be bad for someone" (Derek Parfit) implies a comparison between two states of the same person. As she puts it, "the pairwise comparisons of worlds appealed to within personalism are always in respect of particular people" (6). This does not necessarily imply consequentialism, contrary to what Roberts claims (e.g., 1), at least if we understand the latter, for example, as Philip Pettit does. 1 Moreover, one may very well argue that what is at the heart of the person-affecting intuition is a sense that an action needs to be assessed on the basis of its effect on persons, which would not necessarily imply that such effects require a comparison between two states of the same person. Nevertheless, the extent to which a person-affecting conception--as defined by Roberts--will be in trouble depends on the extent to which comparisons between the same person's states cannot operate. This is precisely where to introduce the idea of a non-identity context, that is, a situation in which not committing an allegedly harmful act would or could also have meant the nonexistence of the allegedly harmed person. For example, had a medical doctor not committed this preconceptional diagnostic mistake (or a father taken a slower or faster means of transportation to come back home), this child would or could not have existed. Can we thus say that the practitioner harmed the child who turned out to be heavily handicapped due, for example, to a genetically transmissible disease (or that the father harmed his child by leaving him with a very polluted environment due to his use of big cars as a means of transportation)?One key feature of Roberts's approach is that she restricts the scope of the non-identity problem to cases where not committing the allegedly harmful action would have made it impossible for this child to have existed ("two-alternative" cases) (26, 319, 325). This entails that whenever this very child could still have come to existence in the allegedly harmful action's absence, whatever the likelihood of such a coming to existence, we would fall outside a non-identity context ("three-alternative" cases) (27; 94-95). What matters to Roberts is whether or not the same child could have been born better than he is, not whether he would, as a matter of fact, have been born at all. The consequence is that in cases where the same child could have been born, say, unhandicapped, the author remains... (shrink)

Ten years ago, researchers using event-related brain potentials to study language comprehension were puzzled by what looked like a Semantic Illusion: Semantically anomalous, but structurally well-formed sentences did not affect the N400 component—traditionally taken to reflect semantic integration—but instead produced a P600 effect, which is generally linked to syntactic processing. This finding led to a considerable amount of debate, and a number of complex processing models have been proposed as an explanation. What these models have in common is that they (...) postulate two or more separate processing streams, in order to reconcile the Semantic Illusion and other semantically induced P600 effects with the traditional interpretations of the N400 and the P600. Recently, however, these multi-stream models have been called into question, and a simpler single-stream model has been proposed. According to this alternative model, the N400 component reflects the retrieval of word meaning from semantic memory, and the P600 component indexes the integration of this meaning into the unfolding utterance interpretation. In the present paper, we provide support for this “Retrieval–Integration ” account by instantiating it as a neurocomputational model. This neurocomputational model is the first to successfully simulate the N400 and P600 amplitude in language comprehension, and simulations with this model provide a proof of concept of the single-stream RI account of semantically induced patterns of N400 and P600 modulations.

Moral norms are the rules of morality, those that people actually follow, and those that we feel people ought to follow, even when they don’t. Historically, the social sciences have been primarily concerned with describing the many forms that moral norms take in various cultures, with the emerging implication that moral norms are mere arbitrary products of culture. Philosophers, on the other hand, have been more concerned with trying to understand the nature and source of rules that all cultures ought (...) to follow, with relatively little regard for what people actually do. The tension between the two approaches has to do with whether there are any standards higher than the whims of culture in determining right and wrong. Typically, the social sciences say “no”, pointing at the diversity of moral beliefs. Most philosophers (along with people of moral conviction) feel that there must be some deeper source of morality than the trends and fads of culture. Unfortunately, the nature and source of such standards has remained something of a mystery. Recent work on the evolution of norms has changed this picture dramatically. (shrink)

Using a new method, we examined whether incidental perception of need-rewarding (positive) objects unintentionally prepares motor action. Participants who varied in their level of need for water were presented with glasses of water (and control objects) that were accompanied by go and no-go cues that required a response (key-press) or withholding a response. Importantly, if need-rewarding objects unintentionally prepare action, presentation of no-go cues should lead to motor inhibition of these prepared motor impulses. Consistent with this hypothesis, results showed that (...) participants relatively high in need for water (and hence, who perceive water as a rewarding, positive object) were slower to react to a successive action probe after withholding a response during perception of water than during perception of the control object, suggesting motor inhibition of unintentionally prepared motor impulses. We propose that incidental perception of need-rewarding objects unintentionally potentiates preparation of motor action to these objects. (shrink)

This book is intended to help transform epistemology - the traditional study of knowledge - into a rigorous discipline by removing conceptual roadblocks and developing formal tools required for a fully naturalized epistemology. The evolutionary approach which Harms favours begins with the common observation that if our senses and reasoning were not reliable, then natural selection would have eliminated them long ago. The challenge for some time has been how to transform these informal musings about evolutionary epistemology into a (...) rigorous theoretical discipline capable of complementing current scientific studies of the evolution of cognition with a philosophically defensible account of meaning and justification.

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

Expectation-based theories of language comprehension, in particular Surprisal Theory, go a long way in accounting for the behavioral correlates of word-by-word processing difficulty, such as reading times. An open question, however, is in which component of the Event-Related brain Potential signal Surprisal is reflected, and how these electrophysiological correlates relate to behavioral processing indices. Here, we address this question by instantiating an explicit neurocomputational model of incremental, word-by-word language comprehension that produces estimates of the N400 and the P600—the two most (...) salient ERP components for language processing—as well as estimates of “comprehension-centric” Surprisal for each word in a sentence. We derive model predictions for a recent experimental design that directly investigates “world-knowledge”-induced Surprisal. By relating these predictions to both empirical electrophysiological and behavioral results, we establish a close link between Surprisal, as indexed by reading times, and the P600 component of the ERP signal. The resultant model thus offers an integrated neurobehavioral account of processing difficulty in language comprehension. (shrink)

With regard to the problem of world poverty, libertarian theories of corrective justice emphasize negative duties and the idea of responsibility whereas utilitarian theories of help concentrate on positive duties based on the capacity of the helper. Thomas Pogge has developed a revised model of compensation that entails positive obligations that are generated by negative duties. He intends to show that the affluent are violating their negative duties to ensure that their conduct will not harm others: They are contributing to (...) and profiting from an unjust global order. But the claim that negative duty generated positive obligations are more acceptable than positive duties is contestable. I examine whether Henry Shue’s model that is integrating negative duties and positive duties is more convincing concerning the foundation of positive duties to protect others. I defend the idea that there are positive duties of justice. This approach can integrate an allocation of positive duties via responsibility and maintain the advantage of an independent foundation of positive duties. (shrink)

Information theory offers a measure of "mutual information" which provides an appropriate measure of tracking efficiency for the naturalistic epistemologist. The statistical entropy on which it is based is arguably the best way of characterizing the uncertainty associated with the behavior of a system, and it is ontologically neutral. Though not appropriate for the naturalization of meaning, mutual information can serve as a measure of epistemic success independent of semantic maps and payoff structures. While not containing payoffs as terms, mutual (...) information places both upper and lower bounds on payoffs. This constitutes a non-trivial relationship to utility. (shrink)

The concept of information tempts us as a theoretical primitive, partly because of the respectability lent to it by highly successful applications of Shannon’s information theory, partly because of its broad range of applicability in various domains, partly because of its neutrality with respect to what basic sorts of things there are. This versatility, however, is the very reason why information cannot be the theoretical primitive we might like it to be. “Information,” as it is variously used, is systematically ambiguous (...) between whether it involves continuous or discrete quantities, causal or noncausal relationships, and intrinsic or relational properties. Many uses can be firmly grounded in existing theory, however. Continuous quantities of information involving probabilities can be related to information theory proper. Information defined relative to systems of rules or conventions can be understood relative to the theory of meaning . A number of causal notions may possibly be located relative to standard notions in physics. Precise specification of these distinct properties involved in the common notion of information can allow us to map the relationships between them. Consequently, while information is not in itself the kind of single thing that can play a significant unifying role, analyzing its ambiguities may facilitate headway toward that goal. (shrink)

Conventional wisdom has it that evolution makes a sham of morality, even if morality is an adaptation. I disagree. I argue that our best current adaptationist theory of meaning offers objective truth conditionsfor signaling systems of all sorts. The objectivity is, however, relative to species – specifically to the adaptive history of the signaling system in question. While evolution may not provide the kind of species independent objective standards that (e.g.) Kantians desire, this should be enough for the practical work (...) of justifying our confidence in the objectivity of moral standards. If you believe morality is an adaptation, you should be a moral realist. (shrink)

Skyrms describes how evolutionary models are helping us understand unselfish or cooperative behaviour in humans and animals. Mechanisms which can stabilize cooperative behaviour are sensitive to population densities, however. This creates the need for agent-based evolutionary models which depict individual interactions, spatial locations, and stochastic effects. One such model suggests that hostile environments may provide conditions conducive to the emergence and stabilization of cooperative behaviour. In particular, simulations show that random extinctions can keep population densities low, provide ongoing colonization opportunities, (...) and insulate cooperative communities from invasion. Agent-based and population models play complementary roles in furthering our understanding evolutionary processes. (shrink)

Stories about near-death experiences draw much attention from the general public and are extensively discussed by medical doctors and neuroscientists. However, though eschatology belongs to their core business, only few theologians participate in the debate. This article proposes a theological interpretation of NDEs as ‘private revelations’. I first give a critical analysis of the development of the modern, allegedly ‘scientific’, concept of NDE. This concept changes concrete personal testimonies into statistical data that are used as scientific evidence for the existence (...) of an immortal soul. Next, the main criticisms against this concept from neurosciences, study of mysticism and philosophy of mind are discussed. Finally, I argue that ‘private revelation’ is a useful model for a theological understanding of NDEs and that an analogy from Thomas Aquinas’ view on prophetic dreams can help to account for the specific circumstance of imminent death. The interpretation I propose can do justice to the impression NDEs make on people, but can also accept and meet some of the most important criticisms raised against the modern concept of NDEs.

The UK Supreme Court in Montgomery v Lanarkshire Health Board adopts an approach to information disclosure in connection with clinical treatment that moves away from medical paternalism towards a more patient-centred approach. In doing so, it reinforces the protection afforded to informed consent and autonomous patient decision making under the law of negligence. However, some commentators have expressed a concern that the widening of the healthcare providers’ duty of disclosure may provide impetus, in future cases, for courts to adopt a (...) more rigorous approach to the application of causation principles. The aim would be to limit liability but, in turn, it would also limit autonomy protection. Such a restrictive approach has recently been adopted in Australia as a result of the High Court decision in Wallace v Kam. This paper considers whether such an approach is likely under English negligence law and discusses case law from both jurisdictions in order to provide a point of comparison from which to scope the post- Montgomery future.

Existing research demonstrates a positive connection between psychedelics and increased nature relatedness. Enhanced affective ties toward nature are widely framed as being built into the pharmakon itself, and the relevance of experiences remains little understood. This paper turns to neoshamanic ayahuasca ceremonies in Europe, exploring the way specialists and attendants refer to nature in speech and performance. I argue that ritual framings performed during these ceremonies provide fertile ground for affective ties to emerge through substance‐induced experiences. I trace such framings (...) by exploring how medicine and healers are being coded; how specific materialities are rendered meaningful; and how individual experiences are discussed at such retreats. I argue that even while participants prioritize individual healing, personal development, or the satisfaction of psychonautical curiosity, environmentalism appears to be anchored by the proceedings themselves. Thus, this paper opens up for analysis ceremonial substance use as a contact zone where coherence is produced intersubjectively. (shrink)

Empirical research has discovered that experimental subjects in ultimatum bargaining situations generally fail to play the decision-theoretic optimum strategy, and instead play something between that strategy and a fair split. In evolutionary dynamics, fair division and nearly fair division strategies often go to fixation and weakly dominated strategies can do quite well. Computer simulations were done using three different ultimatum bargaining games as determinates of fitness. (1) No tendency toward the elimination of weakly dominated strategies was observed, with or without (...) mutation. (2) Strategies making fair demands had sizable basins of attraction. (3) In a system where five different demands can be made, demands closest to (approximately) 91% had the largest basins of attraction. (4) If the strategies have thresholds for acceptable demands, rather than individuated responses to each demand, the apparent optimum demand may be quite low: 64% for one set of trials. (shrink)

Evolving signaling systems can be said to induce partitions on the space of world states as they approach equilibrium. Formalizing this claim provides a general framework for understanding what it means for language to “cut nature at its seams”. In order to avoid taking our current best science as providing the adaptive target for all evolving systems, the state space of the world must be characterized exclusively in terms of the coincidence of stimuli and payoffs that drives the evolution of (...) cognitive complexity. Cognition exploits the reliable clustering of events in this space. Using this framework to analyze our ordinary concepts of truth and justification, it appears that while justification can be a simple matter of conforming to historically entrenched strategies, truth cannot be fully specified on the basis of the system’s causal history, but requires a robust clustering in the larger world state space.

BackgroundIn about one in 10,000 cases, a published article is retracted. This very often means that the results it reports are flawed. Several authors have voiced concerns about the presence of retracted research in the memory of science. In particular, a retracted result is propagated by citing it. In the published literature, many instances are given of retracted articles that are cited both before and after their retraction. Even worse is the possibility that these articles in turn are cited in (...) such a way that the retracted result is propagated further.MethodsWe have conducted a case study to find out how a retracted article is cited and whether retracted results are propagated through indirect citations. We have constructed the entire citation network for this case.ResultsWe show that directly citing articles is an important source of propagation of retracted research results. In contrast, in our case study, indirect citations do not contribute to the propagation of the retracted result.ConclusionsWhile admitting the limitations of a study involving a single case, we think there are reasons for the non-contribution of indirect citations that hold beyond our case study.

This paper shows how Aquinas gradually developed his view on angelic speech. His major texts are summarized and compared to those of contemporaries (sections II-III). Next the texts are analyzed, focusing on three issues: the notion of ‘word’ (section IV), the role of the will (section V), and the need of signification (section VI). With regard to each of these topics, Aquinas’ thought evolved, first by juxtaposing and later by integrating Augustinian and Aristotelian viewpoints. Aquinas reaches his mature position in (...) the Summa Theologiae by radically reinterpretating the meaning of ‘word’ and denying that angelic speech has a semiotic structure. (shrink)

Philosophers spend a lot of time worrying about rules. We worry about how one ought to live, about the rules of justification for beliefs and actions, about what it would be like if the rules of reason were rigorously followed, about what the rules are for scientific enquiry, about which rules govern the meaning of signs and the intentions of agents, and so on. Sometimes, we argue that there are no such rules as most of us want to believe there (...) are, rules which apply to all of us collectively and to each of us individually, which are beyond our ability to change, and whose violation is in some simple sense wrong. To this we often respond that without such rules we are all made somehow less, that our normative deliberations are a sham, or even that the whole business of living becomes somehow pointless.
