In this article we present a new experimental paradigm: comparative visual search. Each half of a display contains simple geometrical objects of three different colors and forms. The two display halves are identical except for one object mismatched in either color or form. The subject's task is to find this mismatch. We illustrate the potential of this paradigm for investigating the underlying complex processes of perception and cognition by means of an eye‐tracking study. Three possible search strategies are outlined, discussed, (...) and reexamined on the basis of experimental results. Each strategy is characterized by the way it partitions the field of objects into “chunks.” These strategies are: (i) Stimulus‐wise scanning with minimization of total scan path length (a “traveling salesman” strategy), (ii) scanning of the objects in fixed‐size areas (a “searchlight” strategy), and (iii) scanning of object sets based on variably sized clusters defined by object density and heterogeneity (a “clustering” strategy). To elucidate the processes underlying comparative visual search, we introduce besides object density a new entropy‐based measure for object heterogeneity. The effects of local density and entropy on several basic and derived eye‐movement variables clearly rule out the traveling salesman strategy, but are most compatible with the clustering strategy.

Future population growth is uncertain and matters for climate policy: higher growth entails more emissions and means more people will be vulnerable to climate-related impacts. We show that how future population is valued importantly determines mitigation decisions. Using the Dynamic Integrated Climate-Economy model, we explore two approaches to valuing population: a discounted version of total utilitarianism (TU), which considers total wellbeing and is standard in social cost of carbon dioxide (SCC) models, and of average utilitarianism (AU), which ignores population size (...) and sums only each time period’s discounted average wellbeing. Under both approaches, as population increases the SCC increases, but optimal peak temperature decreases. The effect is larger under TU, because it responds to the fact that a larger population means climate change hurts more people: for example, in 2025, assuming the United Nations (UN)-high rather than UN-low population scenario entails an increase in the SCC of 85% under TU vs. 5% under AU. The difference in the SCC between the two population scenarios under TU is comparable to commonly debated decisions regarding time discounting. Additionally, we estimate the avoided mitigation costs implied by plausible reductions in population growth, finding that large near-term savings ($billions annually) occur under TU; savings under AU emerge in the more distant future. These savings are larger than spending shortfalls for human development policies that may lower fertility. Finally, we show that whether lowering population growth entails overall improvements in wellbeing—rather than merely cost savings—again depends on the ethical approach to valuing population.

How much should the present generations sacrifice to reduce emissions today, in order to reduce the future harms of climate change? Within climate economics, debate on this question has been focused on so-called “ethical parameters” of social time preference and inequality aversion. We show that optimal climate policy similarly importantly depends on the future of the developing world. In particular, although global poverty is falling and the economic lives of the poor are improving worldwide, leading models of climate economics may (...) be too optimistic about two central predictions: future population growth in poor countries, and future convergence in total factor productivity (TFP). We report results of small modifications to a standard model: under plausible scenarios for high future population growth (especially in sub-Saharan Africa) and for low future TFP convergence, we find that optimal near-term carbon taxes could be substantially larger.

The health co-benefits of CO2 mitigation can provide a strong incentive for climate policy through reductions in air pollutant emissions that occur when targeting shared sources. However, reducing air pollutant emissions may also have an important co-harm, as the aerosols they form produce net cooling overall. Nevertheless, aerosol impacts have not been fully incorporated into cost-benefit modeling that estimates how much the world should optimally mitigate. Here we find that when both co-benefits and co-harms are taken fully into account, optimal (...) climate policy results in immediate net benefits globally, overturning previous findings from cost-benefit models that omit these effects. The global health benefits from climate policy could reach trillions of dollars annually, but will importantly depend on the air quality policies that nations adopt independently of climate change. Depending on how society values better health, economically optimal levels of mitigation may be consistent with a target of 2 °C or lower. (shrink)

The unorthodox life and ideas of Friedrich Nietzsche come alive in this documentary history. Here is a clear picture of the time in which this revolutionary philosopher lived and worked. We meet the luminaries of the age: Richard Wagner, Bismark, Freud and Darwin. We learn of Nietzsche’s famous love affairs, his theories of the Superman, the Antichrist and nihilism, as well as his impact on Twentieth Century thinking. And we see how the Nazi’s annexed and deformed Nietzsche’s thought to (...) serve their purposes. Nietzsche For Beginners is an important introduction to modern philosophy. Plato, Kant, Hegel and Schopenhaur are all evaluated in light of their influence on Nietzsche’s work. Discover why this great thinker defiantly declared, “God is Dead.”. (shrink)

This article explores the role of financial markets for sustainable development. More specifically, the authors ask to what extent financial markets foster and facilitate more sustainable business practices. The authors highlight that their current role is rather modest and conclude that, on the old paths, a paradoxical situation exists. On one hand, financial market participants increasingly integrate environmental, social, and governance criteria into their investment decisions, whereas on the other hand, in terms of organizational reality, there seems to be no (...) real shift toward more sustainable business practices. The authors identify two main challenges within the field of sustainable investments that are relevant for entering new avenues that may help overcome this situation. First, a reorientation toward a long-term paradigm for sustainable investments is important. Second, ESG data must become more trustworthy. From a theoretical point of view, the authors finally highlight the potential market consequences when ESG investment criteria are used. (shrink)

A commonly neglected feature of the so-called Equal Weight View, according to which we should give our peers’ opinions the same weight we give our own, is its prima facie incompatibility with the common picture of philosophy as an armchair activity: an intellectual effort to seek a priori knowledge. This view seems to imply that our beliefs are more likely to be true if we leave our armchair in order to find out whether there actually are peers who, by disagreeing (...) with us, force us to revise our beliefs. This article argues that the Equal Weight View should be spelled out in such a way that not only actual peer disagreement requires us to revise our beliefs, but also merely possible peer disagreement. This result is not a reductio ad absurdum of the view. Quite the opposite: it shows that the view is, contrary to appearance, compatible with our common way of doing philosophy. (shrink)

English summary: Marc Andre Wiegand analyzes the neo-Kantian premises of Gustav Radbruch's legal philosophy.

Scientists have long counseled against interpreting animal behavior in terms of human emotions, warning that such anthropomorphizing limits our ability to understand animals as they really are. Yet what are we to make of a female gorilla in a German zoo who spent days mourning the death of her baby? Or a wild female elephant who cared for a younger one after she was injured by a rambunctious teenage male? Or a rat who refused to push a lever for food (...) when he saw that doing so caused another rat to be shocked? Aren’t these clear signs that animals have recognizable emotions and moral intelligence? With _Wild Justice_ Marc Bekoff and Jessica Pierce unequivocally answer yes. Marrying years of behavioral and cognitive research with compelling and moving anecdotes, Bekoff and Pierce reveal that animals exhibit a broad repertoire of moral behaviors, including fairness, empathy, trust, and reciprocity. Underlying these behaviors is a complex and nuanced range of emotions, backed by a high degree of intelligence and surprising behavioral flexibility. Animals, in short, are incredibly adept social beings, relying on rules of conduct to navigate intricate social networks that are essential to their survival. Ultimately, Bekoff and Pierce draw the astonishing conclusion that there is no moral gap between humans and other species: morality is an evolved trait that we unquestionably share with other social mammals. Sure to be controversial, _Wild Justice_ offers not just cutting-edge science, but a provocative call to rethink our relationship with—and our responsibilities toward—our fellow animals. (shrink)

This paper examines Hume’s understanding of a third doxastic position distinct from belief and disbelief, arguing that his epistemology presupposes different forms of doxastic neutrality. While Hume does not explicitly discuss this third position, his Treatise of Human Nature and Enquiry concerning Human Understanding offer ideas relevant to contemporary debates on suspension of judgement and inquiry. Hume engaged with Pyrrhonian scepticism, finding its suspension of judgement excessive, yet acknowledging that the Pyrrhonian arguments are theoretically difficult to refute. Based on various (...) interpretations of Hume’s critique of Pyrrhonian ideas, we discuss the relevance of his thoughts on suspension of judgement and inquiry through the lens of modern epistemological discussions.

The question of whether biologists should continue to use the Linnaean hierarchy has been a hotly debated issue. Invented before the introduction of evolutionary theory, Linnaeus's system of classifying organisms is based on outdated theoretical assumptions, and is thought to be unable to provide accurate biological classifications. Marc Ereshefsky argues that biologists should abandon the Linnaean system and adopt an alternative that is more in line with evolutionary theory. He traces the evolution of the Linnaean hierarchy from its introduction (...) to the present. He illustrates how the continued use of this system hampers our ability to classify the organic world, and then goes on to make specific recommendations for a post-Linnaean method of classification. Accessible to a wide range of readers by providing introductory chapters to the philosophy of classification and the taxonomy of biology, the book will interest both scholars and students of biology and the philosophy of science.

Marc Hauser puts forth the theory that humans have evolved a universal moral instinct, unconsciously propelling us to deliver judgments of right and wrong independent of gender, education, and religion. Combining his cutting-edge research with the latest findings in cognitive psychology, linguistics, neuroscience, evolutionary biology, economics, and anthropology, Hauser explores the startling implications of his provocative theory vis-à-vis contemporary bioethics, religion, the law, and our everyday lives.

This paper proposes a model of human uniqueness based on an unusual distinction between two contrasted kinds of political competition and political status: (1) antagonistic competition, in quest of dominance (antagonistic status), a zero-sum, self-limiting game whose stake—who takes what, when, how—summarizes a classical definition of politics (Lasswell 1936), and (2) synergistic competition, in quest of merit (synergistic status), a positive-sum, self-reinforcing game whose stake becomes “who brings what to a team’s common good.” In this view, Rawls’s (1971) famous virtual (...) “veil of ignorance” mainly conceals politics’ antagonistic stakes so as to devise the principles of a just, egalitarian society, yet without providing any means to enforce these ideals (Sen 2009). Instead, this paper proposes that human uniqueness flourished under a real “adapted veil of ignorance” concealing the steady inflation of synergistic politics which resulted from early humans’ sturdy egalitarianism. This proposition divides into four parts: (1) early humans first stumbled on a purely cultural means to enforce a unique kind of within-team antagonistic equality—dyadic balanced deterrence thanks to handheld weapons (Chapais 2008); (2) this cultural innovation is thus closely tied to humans’ darkest side, but it also launched the cumulative evolution of humans’ brightest qualities—egalitarian team synergy and solidarity, together with the associated synergistic intelligence, culture, and communications; (3) runaway synergistic competition for differential merit among antagonistically equal obligate teammates is the single politically selective mechanism behind the cumulative evolution of all these brighter qualities, but numerous factors to be clarified here conceal this mighty evolutionary driver; (4) this veil of ignorance persists today, which explains why humans’ unique prosocial capacities are still not clearly understood by science. The purpose of this paper is to start lifting this now-ill-adapted veil of ignorance, thus uncovering the tight functional relations between egalitarian team solidarity and the evolution of human uniqueness.

Models of cognitive vulnerability claim that depressive symptoms arise as a result of an interaction between negative affect and cognitive reactions, in the form of dysfunctional attitudes and negative inferential style. We present a model that complements this approach by focusing on the appraisal processes that elicit and differentiate everyday episodes of emotional experience, arguing that individual differences in appraisal patterns can foster negative emotional experiences related to depression (e.g., sadness and despair). In particular, dispositional appraisal biases facilitating the elicitation (...) of these emotions more frequently and more intensely. This, in turn, is likely to have a negative influence on cognitive processing and emotion regulation in general. (shrink)

Taking his critique of totalitarianizing conceptions of community as a starting point, this text examines Jean-Luc Nancy's work of an ‘ontology of plural singular being’ for its political implications. It argues that while at first this ontology seems to advocate a negative or an anti-politics only, it can also be read as a ‘theory of communicative praxis’ that suggests a certain ethos – in the form of a certain use of symbols (which is expressed only inaptly by the word ‘style’) (...) that would render the ontological plurality of singulars perceptible and practically effective. Finally, some recent texts by Nancy even sidestep the ontology of being-with and face the question of what politics, faced with demands of justice, could be and what a democratic politics could provide. Both of these aspects in Nancy's work, however, still remain to be spelled out more politically. (shrink)

Garber (1983) and Jeffrey (1991, 1995) have both proposed solutions to the old evidence problem. Jeffrey's solution, based on a new probability revision method called reparation, has been generalized to the case of uncertain old evidence and probabilistic new explanation in Wagner 1997, 1999. The present paper reformulates some of the latter work, highlighting the central role of Bayes factors and their associated uniformity principle, and extending the analysis to the case in which an hypothesis bears on a countable (...) family of evidentiary propositions. This extension shows that no Garber-type approach is capable of reproducing the results of generalized reparation. (shrink)

In this paper, I aim to show that agency-based accounts of moral status are more plausible than many have previously thought. I do this by developing a novel account of moral status that takes agency, understood as the capacity for intentional action, to be the necessary and sufficient condition for the possession of moral status. This account also suggests that the capacities required for sentience entail the possession of agency, and the capacities required for agency, entail the possession of sentience. (...) Thus on this account sentient beings possess agency and agents possess sentience. If this is correct, it will show that an Agency Account of moral status can offer a plausible defence of the moral status of all sentient beings, something that previous Agency Accounts have not succeeded in doing. What is more, this account could establish that all sentient animals are not just moral status holders per se, but that they are owed pro tanto obligations regarding continued existence and liberty, similar in kind, though not always in strength, to those owed to humans.

Logical puzzles like the doctrinal paradox raise the problem of how to aggregate individual judgements into a collective judgement, or alternatively, how to merge collectively inconsistent knowledge bases. In this paper, we view judgement aggregation as a function on propositional logic valuations, and we investigate how logic constrains judgement aggregation. In particular, we show that there is no non-dictatorial decision method for aggregating sets of judgements in a logically consistent way if the decision method is local, i.e., only depends on (...) the individual judgements on the proposition under consideration.

In this paper, the relationship between the e-value of a complex hypothesis, H, and those of its constituent elementary hypotheses, Hj, j = 1… k, is analyzed, in the independent setup. The e-value of a hypothesis H, ev, is a Bayesian epistemic, credibility or truth value defined under the Full Bayesian Significance Testing mathematical apparatus. The questions addressed concern the important issue of how the truth value of H, and the truth function of the corresponding FBST structure M, relate to (...) the truth values of its elementary constituents, Hj, and to the truth functions of their corresponding FBST structures Mj, respectively.

To what extent do moral judgments depend on conscious reasoning from explicitly understood principles? We address this question by investigating one particular moral principle, the principle of the double effect. Using web-based technology, we collected a large data set on individuals' responses to a series of moral dilemmas, asking when harm to innocent others is permissible. Each moral dilemma presented a choice between action and inaction, both resulting in lives saved and lives lost. Results showed that: (1) patterns of moral (...) judgments were consistent with the principle of double effect and showed little variation across differences in gender, age, educational level, ethnicity, religion or national affiliation (within the limited range of our sample population) and (2) a majority of subjects failed to provide justifications that could account for their judgments. These results indicate that the principle of the double effect may be operative in our moral judgments but not open to conscious introspection. We discuss these results in light of current psychological theories of moral cognition, emphasizing the need to consider the unconscious appraisal system that mentally represents the causal and intentional properties of human action.

This ethnographic study of political life in the department of the Yonne, in the Burgundy region, explores a still richly Balzacian provincial world. The author, a French anthropologist, has extensive field experience in Ethiopia. Deploying the insights and methods of social anthropology by drawing on local history, interviews and participant observation, Abélès describes politicians at every level, from municipal officers to Members of Parliament and Ministers. He provides a clear picture of the process of 'decentralization' initiated by the Socialist government (...) in 1982, and undermines the simplistic notion of 'centralist France'. This book, which develops a fresh perspective on political life in France, past and present, illustrates more generally an exciting approach to modern political phenomena, from the point of view of anthropology.

Conflicts of interest are rampant in the American medical community. Today it is not uncommon for doctors to refer patients to clinics or labs in which they have a financial interest (40% of physicians in Florida invest in medical centers); for hospitals to offer incentives to physicians who refer patients (a practice that can lead to unnecessary hospitalization); or for drug companies to provide lucrative give-aways to entice doctors to use their "brand name" drugs (which are much more expensive than (...) generic drugs). In Medicine, Money and Morals, Marc A. Rodwin draws on his own experience as a health lawyer--and his research in health ethics, law, and policy--to reveal how financial conflicts of interest can and do negatively affect the quality of patient care. He shows that the problem has become worse over the last century and provides many actual examples of how doctors' decisions are influenced by financial considerations. We learn how two California physicians, for example, resumed referrals to Pasadena General Hospital only after the hospital started paying $70 per patient (their referrals grew from 14 in one month to 82 in the next). As Rodwin writes, incentives such as this can inhibit a doctor from taking action when a hospital fails to provide proper service, and may also lead to the unnecessary hospitalization of patients. We also learn of a Wyeth-Ayerst Labs promotion in which physicians who started patients on INDERAL (a drug for high blood pressure, angina, and migraines) received 1000 mileage points on American Airlines for each patient (studies show that promotions such as this have a direct effect on a doctor's choice of drug). Rodwin reveals why the medical community has failed to regulate conflicts of interest: peer review has little authority, state licensing boards are usually ignorant of abuses, and the AMA code of ethics has historically been recommended rather than required. He examines what can be learned from the way society has coped with the conflicts of interest of other professionals --lawyers, government officials, and businessmen--all of which are held to higher standards of accountability than doctors. And he recommends that efforts be made to prohibit and regulate certain kinds of activity (such as kickbacks and self-referrals), to monitor and regulate conduct, and to provide penalties for improper conduct. Our failure to face physicians' conflicts of interest has distorted the way medicine is practiced, compromised the loyalty of doctors to patients, and harmed society, the integrity of the medical profession, and patients. For those concerned with the quality of health care or medical ethics, Medicine, Money and Morals is a provocative look into the current health care crisis and a powerful prescription for change.

The prevalent views of animal liberty among animal advocates suggest that liberty is merely instrumentally valuable and invasive paternalism is justified. In contrast to this popular view, I argue that liberty is intrinsically good for animals. I suggest that animal well-being is best accommodated by an Objective List Theory and that liberty is an irreducible component of animal well-being. As such, I argue that it is good for animals to possess liberty even if possessing liberty does not contribute towards their (...) subjective well-being, and even in some cases where it has a negative effect upon their subjective well-being. To establish this view I argue that if animals are agents, as I assume they are, then like humans they must be able to determine the course of their own lives (to some extent). Further, having the opportunity to self-determine one’s life just is the very same thing as liberty, and having the opportunity to determine the course of one’s life is intrinsically good. Thus liberty has intrinsic value for humans and animals. So, in addition to the instrumental harms of having one’s liberty restricted, I claim that restricting animals’ liberty in principle harms them because it undermines their capacity for self-determination and fails to acknowledge their authority as agents to make their own choices.

What is a fair distribution of resources and other goods when individuals are partly responsible for their achievements? This book develops a theory of fairness incorporating a concern for personal responsibility, opportunities and freedom. With a critical perspective, it makes accessible the recent developments in economics and philosophy that define social justice in terms of equal opportunities. It also proposes new perspectives and original ideas. The book separates mathematical sections from the rest of the text, so that the main concepts (...) and ideas are easily accessible to non-technical readers. -/- It is often thought that responsibility is a complex notion, but this monograph proposes a simple analytical framework that makes it possible to disentangle the different concepts of fairness that deal with neutralizing inequalities for which the individuals are not held responsible, rewarding their effort, respecting their choices, or staying neutral with respect to their responsibility sphere. It dwells on paradoxes and impossibilities only as a way to highlight important ethical options and always proposes solutions and reasonable compromises among the conflicting values surrounding equality and responsibility. -/- The theory is able to incorporate disincentive problems and is illustrated in the examination of applied policy issues such as: income redistribution when individuals may be held responsible for their choices of labor supply or education; social and private insurance when individuals may be held responsible for their risky lifestyle; second chance policies; the measurement of inequality of opportunities and social mobility.

Policy-makers must sometimes choose between an alternative which has somewhat lower expected value for each person, but which will substantially improve the outcomes of the worst off, or an alternative which has somewhat higher expected value for each person, but which will leave those who end up worst off substantially less well off. The popular ex ante Pareto principle requires the choice of the alternative with higher expected utility for each. We argue that ex ante Pareto ought to be rejected (...) because it conflicts with the requirement that, when possible, one ought to decide as one would with full information. We apply our argument in an analysis of US policy on screening for breast cancer. -/- . (shrink)

Epistemologists have a special fondness for David Hume. Even Kant-obsessed a priorists admire the honesty, directness and elegance of his thinking. He is the Mozart of analytic philosophy rather than the Bach. Sparkling ideas, icy clarity and popular delivery make his writings the standard for good philosophy. 'Try to think like Hume' is pretty decent advice. But is that his only use today—to be emulated in style and approach? This volume is a collective 'no'. A team of top epistemologists and (...) historians join forces to demonstrate the relevance of Humean ideas to the most current questions and debates. Hume dribbles into the following themes, much to the advantage of each: knowledge, belief, inquiry and suspension, reason and reasons, scepticism, hinge epistemology, naturalized epistemology, the ethics of belief and moral epistemology, virtue and vice epistemology, the epistemology of testimony. Epistemologists who discount history and historians who halt at 1950 should gallop to this volume and start reading. Neither perspective will survive. (shrink)

This paper is concerned with the problem of selfidentification in the domain of action. We claim that this problem can arise not just for the self as object, but also for the self as subject in the ascription of agency. We discuss and evaluate some proposals concerning the mechanisms involved in selfidentification and in agencyascription, and their possible impairments in pathological cases. We argue in favor of a simulation hypothesis that claims that actions, whether overt or covert, are centrally simulated (...) by the neural network, and that this simulation provides the basis for action recognition and attribution.
