Theories of decision-making and its neural substrates have long assumed the existence of two distinct and competing valuation systems, variously described as goal-directed vs. habitual, or, more recently and based on statistical arguments, as model-free vs. model-based reinforcement-learning. Though both have been shown to control choices, the cognitive abilities associated with these systems are under ongoing investigation. Here we examine the link to cognitive abilities, and find that individual differences in processing speed covary with a shift from model-free to model-based (...) choice control in the presence of above-average working memory function. This suggests shared cognitive and neural processes; provides a bridge between literatures on intelligence and valuation; and may guide the development of process models of different valuation components. Furthermore, it provides a rationale for individual differences in the tendency to deploy valuation systems, which may be important for understanding the manifold neuropsychiatric diseases associated with malfunctions of valuation.

The persistent educational challenges that fractions pose call for developing novel instructional methods to better prepare students for fraction learning. Here, we examined the effects of a 24-session, Cuisenaire rod intervention on a building block for symbolic fraction knowledge, continuous and discrete non-symbolic proportional reasoning, in children who have yet to receive fraction instruction. Participants were 34 second-graders who attended the intervention (intervention group) and 15 children who did not participate in any sessions (control group). As attendance at the intervention (...) sessions was irregular (median = 15.6 sessions, range = 1–24), we specifically examined the effect of the number of sessions completed on their non-symbolic proportional reasoning. Our results showed that children who attended a larger number of sessions increased their ability to compare non-symbolic continuous proportions. However, contrary to our expectations, they also decreased their ability to compare misleading discretized proportions. In contrast, children in the Control group did not show any change in their performance. These results provide further evidence on the malleability of non-symbolic continuous proportional reasoning and highlight the rigidity of counting knowledge interference on discrete proportional reasoning.

En la sección titulada Irreversibilidad y el Poder de Perdonar en La Condición Humana, Arendt afirma que “el descubridor del papel del perdón en la esfera de los asuntos humanos fue Jesús de Nazaret”. En lo que sigue, quisiéramos aproximarnos al uso antiguo del verbo griego sungignôskô que a nuestro entender cumple el mismo papel que Arendt advierte en esta supuesta novedad cristiana —la “mutua exoneración de lo que se ha hecho”—, no sólo para entender en qué consistiría el descubrimiento (...) que Arendt atribuye a Jesús, sino porque creemos que la idea de que los griegos desconocían la facultad de perdonar es, si no falsa, al menos imprecisa. In the section titled Irreversibility and the Power to Forgive in the Human Condition, Arendt claims that “the discoverer of the role of forgiveness in the sphere of human affairs was Jesus of Nazareth”. In what follows, we would like to approach the ancient use of the Greek verb sungignôskô which, in our opinion, fulfills the same role that Arendt finds in this alleged Christian novelty —the “mutual exoneration of what has been done”— not only to understand what would the actual discovery Arendt attributes to Jesus imply, but because we believe claiming the Greeks were unaware of the faculty of forgiveness is, if not false, at least inaccurate.

Given the ubiquitous nature of love, numerous theories have been proposed to explain its existence. One such theory refers to love as a commitment device, suggesting that romantic love evolved to foster commitment between partners and enhance their reproductive success. In the present study, we investigated this hypothesis using a large-scale sample of 86,310 individual responses collected across 90 countries. If romantic love is universally perceived as a force that fosters commitment between long-term partners, we expected that individuals likely to (...) suffer greater losses from the termination of their relationships—including people of lower socioeconomic status, those with many children, and women—would place a higher value on romantic love compared to people with higher status, those with fewer children, and men. These predictions were supported. Additionally, we observed that individuals from countries with a higher (vs. lower) Human Development Index placed a greater level of importance on romantic love, suggesting that modernization might influence how romantic love is evaluated. On average, participants worldwide were unwilling to commit to a long-term romantic relationship without love, highlighting romantic love’s universal importance. (shrink)

This article examines some current U.S. policies regarding the ethics of information control in scientific research, such as the requirements for “timely” publication and information sufficient for replication. The appropriateness of these policies is called into question by recent work in science studies, which suggest the importance of informal and nonlinguistic channels of information and the impossibility of exact replication of experiments. Policy change is recommended, but it needs to take into account considerations of privacy and enforceability.

Gestures—hand movements that accompany speech and express ideas—can help children learn how to solve problems, flexibly generalize learning to novel problem‐solving contexts, and retain what they have learned. But does it matter who is doing the gesturing? We know that producing gesture leads to better comprehension of a message than watching someone else produce gesture. But we do not know how producing versus observing gesture impacts deeper learning outcomes such as generalization and retention across time. Moreover, not all children benefit (...) equally from gesture instruction, suggesting that there are individual differences that may play a role in who learns from gesture. Here, we consider two factors that might impact whether gesture leads to learning, generalization, and retention after mathematical instruction: (1) whether children see gesture or do gesture and (2) whether a child spontaneously gestures before instruction when explaining their problem‐solving reasoning. For children who spontaneously gestured before instruction, both doing and seeing gesture led to better generalization and retention of the knowledge gained than a comparison manipulative action. For children who did not spontaneously gesture before instruction, doing gesture was less effective than the comparison action for learning, generalization, and retention. Importantly, this learning deficit was specific to gesture, as these children did benefit from doing the comparison manipulative action. Our findings are the first evidence that a child's use of a particular representational format for communication (gesture) directly predicts that child's propensity to learn from using the same representational format.

Advancements in early diagnosis and novel treatments for children with complex and chronic needs have improved their chances of survival. But many survive with complex medical needs and ongoing medical management in the setting of prognostic uncertainty. Their medical care relies more and more on preference-sensitive decisions, requiring medical team and family engagement in ethically challenging situations. Many families are unprepared as they face these ethical challenges and struggle to access relevant ethical resources. In this paper, Timmy’s narrative, situated in (...) the context of what is known about ethical challenges in the care of children with chronic critical illness (CCI), serves as a case study of the gap in available ethical resources to guide families in their approach to difficult decision making for children with significant medical complexity and CCI. Our author group, inclusive of parents of children with complex medical needs and medical professionals, identifies domains of ethical challenges facing families of children with CCI and we highlight the development of family/caregiver-oriented ethics resources as an essential expansion of pediatric bioethics.

Life expectancy and health differ greatly between emerging and developed countries and within countries. Global dependence on fossil fuels contributes to health inequalities through air pollution, the geopolitics of scarce resources and probable climate change arising from global warming. Substituting for fossil fuels (C), hydrogen (H2), as vector and store of energy produced from low-carbon and/or renewable sources could reduce health inequalities by improving the environment. It is unlikely that the global market would initiate such a change. Nation-states would not (...) act alone and would need to cooperate in leading it. Global recession might be the incentive that is needed to restructure a C-economy into an H2-economy. Yet, the transition would carry high costs, which would have to be borne by the developed countries in order to achieve a new treaty that included emerging countries. H2 for C is thus not only a technical fix, but also a global-ethical choice. (shrink)

How is medical knowledge made? There have been radical changes in recent decades, through new methods such as consensus conferences, evidence-based medicine, translational medicine, and narrative medicine. Miriam Solomon explores their origins, aims, and epistemic strengths and weaknesses; and she offers a pluralistic approach for the future.

The question of whether it is ever permissible to believe on insufficient evidence has once again become a live question. Greater attention is now being paid to practical dimensions of belief, namely issues related to epistemic virtue, doxastic responsibility, and voluntarism. In this book, McCormick argues that the standards used to evaluate beliefs are not isolated from other evaluative domains. The ultimate criteria for assessing beliefs are the same as those for assessing action because beliefs and actions are both products (...) of agency. Two important implications of this thesis, both of which deviate from the dominant view in contemporary philosophy, are 1) it can be permissible to believe for non-evidential reasons, and 2) we have a robust control over many of our beliefs, a control sufficient to ground attributions of responsibility for belief.

The ArgumentThis paper describes the way in which a simple device, the pregnancy wheel, has been used by the medical profession to impose a new way of measuring and experiencing pregnancy.The change involves counting in weeks instead of counting in months and it is gradually replacing a commonsensical method that had deep physiological and cultural roots. In contrast, the medical methodology of counting forty weeks is more complicated and lacks direct connections to the events of pregnancyIn the encounter between the (...) doctor and the pregnant woman the pregnancy wheel has a variety of uses, among them determinations of the age and estimated size of the fetus.It plays an additional role, however, in the medicalization of pregnancy by providing the doctor with privileged information. It also influences modes of thinking through the way in which it deals with the question of the beginning of pregnancy, a question that has clear moral implications. (shrink)

Nathanson asks how we can properly understand terrorism such that it is always unjustified, and does not thereby preclude justified warfare. By means of a novel ruleutilitarian argument bolstering the inviolability of noncombatants, he hopes to have crafted such an understanding. While praising Nathanson’s rigor and originality, this paper questions the moral-theoretic completeness of his procedure, and then raises challenges from two directions: an argument for the justifiability of terrorism in certain circumstances, and an argument against the justifiability of warfare (...) under any circumstances. The first challenge can probably be met by the argumentative resources of the book; it is possible that the second cannot, though perhaps it unfairly asks the author to go beyond the scope of the project.

This imagined conversation between Sir Isaac Newton and the priestess Diotima (from Plato’s Symposium) examines the possible merits of reductionism in scientific inquiry, finding it of value both as a methodology for the simplification of scientific explanations and for the decisive elimination of metaphysically extravagant scientific hypotheses. However, the power and narrative appeal of reductionism renders its overuse a perennial danger. Science thus needs reductionism, but also needs reminding that its task is to explain natural phenomena, not to explain them (...) away. (shrink)

Recent scholarship has gone a long way toward placing Locke in his intellectual and historical context, and thus in coming to see the respect in which his work has a previously unacknowledged conceptual unity. There remains, however, some difficulty in reconciling the style, purpose and content of his two major works. The Essay Concerning Human Understanding is usually read as primarily concerned with issues in epistemology and philosophy of science, while the Two Treatises of Government is regarded as less systematically (...) rigorous, or at worst ad hoc political analysis. These two sides of Locke thus remain virtually unrelated fields of specialization among interpreters. ;My dissertation is a contribution to the project of understanding Locke's work as a connected whole; without attributing to him an attitude of scientific reductionism, I argue that the account which Locke gives of personal property in the Second Treatise bears an important relation to his account of qualities and personal identity in the Essay. Specifically, I try to make plausible the claim that there is in Locke a direct analogy between the property of a human person, on one hand, and the properties of a natural substance on the other. I suggest that Locke's methodological atomism in science and epistemology parallels his qualifiedly individualistic political theory, and thus that his claims about private property can be understood in terms of a broader philosophical context than is usually supposed. ;As part of a larger project concerning the genealogy of the concept of property and the relation between metaphysics and morality, I expect this work to have useful implications regarding much of contemporary moral and political theory. Given the historical influence of Locke's political work, a careful analysis of it in terms of its epistemological and scientific grounding should contribute to a rethinking of much twentieth century work on property and justice.

A new, social epistemology of science that addresses practical as well as theoretical concerns.

For the last forty years, two claims have been at the core of disputes about scientific change: that scientists reason rationally and that science is progressive. For most of this time discussions were polarized between philosophers, who defended traditional Enlightenment ideas about rationality and progress, and sociologists, who espoused relativism and constructivism. Recently, creative new ideas going beyond the polarized positions have come from the history of science, feminist criticism of science, psychology of science, and anthropology of science. Addressing the (...) traditional arguments as well as building on these new ideas, Miriam Solomon constructs a new epistemology of science. After discussions of the nature of empirical success and its relation to truth, Solomon offers a new, social account of scientific rationality. She shows that the pursuit of empirical success and truth can be consistent with both dissent and consensus, and that the distinction between dissent and consensus is of little epistemic significance. In building this social epistemology of science, she shows that scientific communities are not merely the locus of distributed expert knowledge and a resource for criticism but also the site of distributed decision making. Throughout, she illustrates her ideas with case studies from late-nineteenth- and twentieth-century physical and life sciences. Replacing the traditional focus on methods and heuristics to be applied by individual scientists, Solomon emphasizes science funding, administration, and policy. One of her goals is to have a positive influence on scientific decision making through practical social recommendations. (shrink)

Greaves and Wallace argue that conditionalization maximizes expected accuracy. In this paper I show that their result only applies to a restricted range of cases. I then show that the update procedure that maximizes expected accuracy in general is one in which, upon learning P, we conditionalize, not on P, but on the proposition that we learned P. After proving this result, I provide further generalizations and show that much of the accuracy-first epistemology program is committed to KK-like iteration principles (...) and to the existence of a class of propositions that rational agents will be certain of if and only if they are true.

The aim of this paper is to describe a problem for calibrationism: a view about higher order evidence according to which one's credences should be calibrated to one's expected degree of reliability. Calibrationism is attractive, in part, because it explains our intuitive judgments, and provides a strong motivation for certain theories about higher order evidence and peer disagreement. However, I will argue that calibrationism faces a dilemma: There are two versions of the view one might adopt. The first version, I (...) argue, has the implausible consequence that, in a wide range of cases, calibrationism is the only constraint on rational belief. The second version, in addition to having some puzzling consequences, is unmotivated. At the end of the paper I sketch a possible solution. (shrink)

This philosophical dialogue explores some of the barriers to an adequate definition of general health, encompassing physical, social, and mental/emotional well-being. Many of the putative obstacles to such a definition—concerns about subjectivity, cultural difference, marginal cases, etc.—prove to be chimerical once the characters take seriously the Peircean insight that truth-claims methodologically grounded in people’s lives, experiences, and conversations need not be apodictic to be useful. Drawing on Canguilhem and others, the characters critically discuss a proposed definition of health: a dynamic (...) equilibrium by which a human being thrives in relation to its situation. Although they do not manage to resolve all of this definition’s difficulties, or all of their differences, their interaction in some ways models the ongoing task of inquiry. (shrink)

Lucius Annaeus Seneca was a Roman Stoic philosopher, dramatist, statesman, and advisor to the emperor Nero, all during the Silver Age of Latin literature. The Complete Works of Lucius Annaeus Seneca is a fresh and compelling series of new English-language translations of his works in eight accessible volumes. Edited by world-renowned classicists Elizabeth Asmis, Shadi Bartsch, and Martha C. Nussbaum, this engaging collection restores Seneca—whose works have been highly praised by modern authors from Desiderius Erasmus to Ralph Waldo Emerson—to his (...) rightful place among the classical writers most widely studied in the humanities. _ On Benefits_, written between 56 and 64 CE, is a treatise addressed to Seneca’s close friend Aebutius Liberalis. The longest of Seneca’s works dealing with a single subject—how to give and receive benefits and how to express gratitude appropriately—_On Benefits _is the only complete work on what we now call “gift exchange” to survive from antiquity. Benefits were of great personal significance to Seneca, who remarked in one of his later letters that philosophy teaches, above all else, to owe and repay benefits well. (shrink)

In this paper, I begin by defending permissivism: the claim that, sometimes, there is more than one way to rationally respond to a given body of evidence. Then I argue that, if we accept permissivism, certain worries that arise as a result of learning that our beliefs were caused by the communities we grew up in, the schools we went to, or other irrelevant influences dissipate. The basic strategy is as follows: First, I try to pinpoint what makes irrelevant influences (...) worrying and I come up with two candidate principles. I then argue that one principle should be rejected because it is inconsistent with permissivism. The principle we should accept implies that it is sometimes rational to maintain our beliefs, even upon learning that they were caused by irrelevant influences. (shrink)

The work of Tversky, Kahneman and others suggests that people often make use of cognitive heuristics such as availability, salience and representativeness in their reasoning and decision making. Through use of a historical example--the recent plate tectonics revolution in geology--I argue that such heuristics play a crucial role in scientific decision making also. I suggest how these heuristics are to be considered, along with noncognitive factors (such as motivation and social structures) when drawing historical and epistemological conclusions. The normative perspective (...) is community-wide, contextual, and instrumental. (shrink)

Embodied approaches in cognitive science hold that the body is crucial for cognition. What this claim amounts to, however, still remains unclear. This paper contributes to its clarification by confronting three ways of understanding embodiment—the sensorimotor approach, extended cognition and enactivism—with Locked-in syndrome. LIS is a case of severe global paralysis in which patients are unable to move and yet largely remain cognitively intact. We propose that LIS poses a challenge to embodied approaches to cognition requiring them to make explicit (...) the notion of embodiment they defend and its role for cognition. We argue that the sensorimotor and the extended functionalist approaches either fall short of accounting for cognition in LIS from an embodied perspective or do it too broadly by relegating the body only to a historical role. Enactivism conceives of the body as autonomous system and of cognition as sense-making. From this perspective embodiment is not equated with bodily movement but with forms of agency that do not disappear with body paralysis. Enactivism offers a clarifying perspective on embodiment and thus currently appears to be the framework in embodied cognition best suited to address the challenge posed by LIS. (shrink)

I investigate what we mean when we hold people responsible for beliefs. I begin by outlining a puzzle concerning our ordinary judgments about beliefs and briefly survey and critique some common responses to the puzzle. I then present my response where I argue a sense needs to be articulated in which we do have a kind of control over our beliefs if our practice of attributing responsibility for beliefs is appropriate. In developing this notion of doxastic control, I draw from (...) John Fischer's discussions of “guidance control”. A central feature of this kind of control is the idea of “ownership”. I argue that we can own our beliefs and that we expect each other to do so. We take responsibility for our beliefs and taking responsibility includes taking control of them. I end by considering objections to my view as well as some implications of it. (shrink)

This dialogue discusses a proposal for the legalization of torture under specific circumstances and contrasts it with arguments for a total ban on torture. We consider three types of objection: first, that the difficulty of having adequate knowledge renders the stock “ticking bomb” scenario such a low-probability hypothetical as to present no realistic threat to a policy banning all torture; second, that empirically the information gleaned from torture is so unlikely to be reliable that it could not justify the moral (...) risk; and third, that sanctioning torture, even if only under the most extreme circumstances, would generate a ‘culture of torture,’ hence undermining fragile advances in international human rights rooted in unwavering commitment to human dignity. Compelling as these arguments appear, not all the conversants are wholly convinced by them; to this extent the dialogue ends aporetically. (shrink)
