Lara Buchak sets out a new account of rational decision-making in the face of risk. She argues that the orthodox view is too narrow, and suggests an alternative, more permissive theory: one that allows individuals to pay attention to the worst-case or best-case scenario, and vindicates the ordinary decision-maker.

There are currently two robust traditions in philosophy dealing with doxastic attitudes: the tradition that is concerned primarily with all-or-nothing belief, and the tradition that is concerned primarily with degree of belief or credence. This paper concerns the relationship between belief and credence for a rational agent, and is directed at those who may have hoped that the notion of belief can either be reduced to credence or eliminated altogether when characterizing the norms governing ideally rational agents. It presents a (...) puzzle which lends support to two theses. First, that there is no formal reduction of a rational agent’s beliefs to her credences, because belief and credence are each responsive to different features of a body of evidence. Second, that if our traditional understanding of our practices of holding each other responsible is correct, then belief has a distinctive role to play, even for ideally rational agents, that cannot be played by credence. The question of which avenues remain for the credence-only theorist is considered. (shrink)

This paper provides an account of what it is to have faith in a proposition p, in both religious and mundane contexts. It is argued that faith in p doesn’t require adopting a degree of belief that isn’t supported by one’s evidence but rather it requires terminating one’s search for further evidence and acting on the supposition that p. It is then shown, by responding to a formal result due to I.J. Good, that doing so can be rational in a (...) number of circumstances. If expected utility theory is the correct account of practical rationality, then having faith can be both epistemically and practically rational if the costs associated with gathering further evidence or postponing the decision are high. If a more permissive framework is adopted, then having faith can be rational even when there are no costs associated with gathering further evidence. (shrink)

In the peer disagreement debate, three intuitively attractive claims seem to conflict: there is disagreement among peers on many important matters; peer disagreement is a serious challenge to one’s own opinion; and yet one should be able to maintain one’s opinion on important matters. I show that contrary to initial appearances, we can accept all three of these claims. Disagreement significantly shifts the balance of the evidence; but with respect to certain kinds of claims, one should nonetheless retain one’s beliefs. (...) And one should retain them even though these beliefs would not be supported by the new total evidence if one didn’t already hold them. (shrink)

The ‘rollback argument,’ pioneered by Peter van Inwagen, purports to show that indeterminism in any form is incompatible with free will. The argument has two major premises: the first claims that certain facts about chances obtain in a certain kind of hypothetical situation, and the second that these facts entail that some actual act is not free. Since the publication of the rollback argument, the second claim has been vehemently debated, but everyone seems to have taken the first claim for (...) granted. Nevertheless, the first claim is totally unjustified. Even if we accept the second claim, therefore, the argument gives us no reason to think that free will and indeterminism are incompatible. Furthermore, seeing where the rollback argument goes wrong illuminates how a certain kind of incompatibilist, the ‘chance-incompatibilist,’ ought to think about free will and chance, and points to a possibility for free will that has remained largely unexplored.

One phenomenon arising in epistemic life is allegiance to, and break from, a tradition. This phenomenon has three central features. First, individuals who adhere to a tradition seem to respond dogmatically to evidence against their tradition. Second, individuals from different traditions appear to see the same evidence differently. And third, conversion from one tradition to another appears to be different in kind from ordinary belief shift. This paper uses recent work on the nature and rationality of faith to show that (...) these features can all emerge from individuals acting rationally—in particular, from individuals rationally having faith in the core assumptions of their traditions. One upshot is that we don't need to employ the idea of incommensurability to explain these features. (shrink)

It is sometimes said that faith is recalcitrant in the face of new evidence, but it is puzzling how such recalcitrance could be rational or laudable. I explain this aspect of faith and why faith is not only rational, but in addition serves an important purpose in human life. Because faith requires maintaining a commitment to act on the claim one has faith in, even in the face of counter-evidence, faith allows us to carry out long-term, risky projects that we (...) might otherwise abandon. Thus, faith allows us to maintain integrity over time. (shrink)

Faith is a central attitude in Christian religious practice. The problem of faith and reason is the problem of reconciling religious faith with the standards for our belief-forming practices in general (‘ordinary epistemic standards’). In order to see whether and when faith can be reconciled with ordinary epistemic standards, we first need to know what faith is. This chapter examines and catalogues views of propositional faith: faith that p. It is concerned with the epistemology of such faith: what cognitive attitudes (...) does such faith require, what epistemic norms govern these attitudes, and whether Christian faith can ever adhere to them.

In “Can it be rational to have faith?”, it was argued that to have faith in some proposition consists, roughly speaking, in stopping one’s search for evidence and committing to act on that proposition without further evidence. That paper also outlined when and why stopping the search for evidence and acting is rationally required. Because the framework of that paper was that of formal decision theory, it primarily considered the relationship between faith and degrees of belief, rather than between faith (...) and belief full stop. This paper explores the relationship between rational faith and justified belief, by considering four prominent proposals about the relationship between belief and degrees of belief, and by examining what follows about faith and belief according to each of these proposals. It is argued that we cannot reach consensus concerning the relationship between faith and belief at present because of the more general epistemological lack of consensus over how belief relates to rationality: in particular, over how belief relates to the degrees of belief it is rational to have given one’s evidence.

Decision theory has at its core a set of mathematical theorems that connect rational preferences to functions with certain structural properties. The components of these theorems, as well as their bearing on questions surrounding rationality, can be interpreted in a variety of ways. Philosophy’s current interest in decision theory represents a convergence of two very different lines of thought, one concerned with the question of how one ought to act, and the other concerned with the question of what action consists (...) in and what it reveals about the actor’s mental states. As a result, the theory has come to have two different uses in philosophy, which we might call the normative use and the interpretive use. It also has a related use that is largely within the domain of psychology, the descriptive use. This essay examines the historical development of decision theory and its uses; the relationship between the norm of decision theory and the notion of rationality; and the interdependence of the uses of decision theory.

Individual differences in convergent and divergent thinking may uniquely explain variation in analogical reasoning ability. Across two studies we investigated the relative influences of divergent and convergent thinking as predictors of verbal analogy performance. Performance on both convergent thinking and divergent thinking uniquely predicted performance on both analogy selection and analogical generation tasks. Moreover, convergent and divergent thinking were predictive above and beyond creative behaviours in Study 1 and a composite measure of crystallised intelligence in Study 2. Verbal analogies in (...) Study 2 also varied in semantic distance, with results demonstrating divergent thinking as a stronger predictor of analogy generation for semantically far than for semantically near analogies. Results thus further illuminate the link between analogical reasoning and creative cognition by demonstrating convergent and di.. (shrink)

Notable examples of macaronics, the insertion of foreign vocabulary into poetry, are attributed to the well-known eighth-century poet, Abū Nuwās, who experimented with mixing Persian in his Arabic poetry but whose motivation remains unclear. This article looks at a selection of his and other macaronic verses ranging from the seventh to tenth centuries and argues that Persian was inserted deliberately as a marker of a Persian identity, standing for the “foreign Other.” Far from being a sign of a pro-Persian shuʿūbī (...) sentiment, the employment of Persian only reinforces the established hierarchy of the two identities in that period. By the tenth century, however, this hierarchy is cleverly flipped on its head in a macaronic poem by the popular Iraqi poet, Ibn al-Ḥajjāj. While many of the examples are comic and even obscene in character, this article shows that the employment of Persian in Arabic poetry was a deliberate practice with serious and meaningful implications.

The good of those who are worse off matters more to the overall good than the good of those who are better off does. But being worse off than one’s fellows is not itself bad; nor is inequality itself bad; nor do differences in well-being matter more when well-being is lower in an absolute sense. Instead, the good of the relatively worse-off weighs more heavily in the overall good than the good of the relatively better-off does, in virtue of the (...) fact that the former are relatively worse off. This paper articulates and defends the view just described. (shrink)

Suppose we want to do the most good we can with a particular sum of money, but we cannot be certain of the consequences of different ways of making use of it. This article explores how our attitudes towards risk and ambiguity bear on what we should do. It shows that risk-avoidance and ambiguity-aversion can each provide good reason to divide our money between various charitable organizations rather than to give it all to the most promising one. It also shows (...) how different attitudes towards risk and ambiguity affect whether we should give to an organization which does a small amount of good for certain or to one which does a large amount of good with some small or unknown probability.

This paper addresses the question of whether gathering additional evidence is always rationally required, both from the point of view of instrumental rationality and of epistemic rationality. It is shown that in certain situations, it is not instrumentally rational to look for more evidence before making a decision. These are situations in which the risk of “misleading” evidence – a concept that has both instrumental and epistemic senses – is not offset by the gains from the possibility of non-misleading evidence. (...) These situations also undermine a particular argument for the claim that it is epistemically rational to look for more evidence, though it is argued that the relationship between instrumental and epistemic rationality makes such arguments flawed to begin with. Furthermore, these situations show us that our epistemic and our practical goals sometimes point us in different directions, not merely because of our limited resources or because our desires are sometimes best served by being in particular epistemic states, but because of the nature of rational action.

Many view cancellation as a method for holding influential personalities accountable for bad behavior, while others think cancelling amounts to censorship and bullying. I hold that neither of these accounts are worth pursuing, especially if the aim is social progress. In this paper, I offer a situated account of cancellation and cancel culture, locating the phenomenon in our exclusionary history while examining the social dynamics of belief. When we situate cancel culture, we can see how problematic instances of cancelling are (...) embedded in ignorance. While combatting ignorance appears to call for a remedy rooted in feminist standpoint epistemology, there are risks in adopting naive practices of deference. Applying criticisms of epistemic injustice and adopting Táíwò’s elite capture framework, I explain how well-intentioned cancelling can work against social movements. Since epistemic trust mechanisms discourage self-reflection and belief revision, the relevant tactics for enacting social change—coalition politics and education—seem out of reach. I conclude by sketching cancel culture as a diagnostic tool: cancellation can be used appropriately in marginalized communities, but when it comes to combatting ignorance among privileged folks, we should view cancel culture as a method for determining where our social institutions are failing us.

This essay argues that when setting climate policy, we should place more weight on worse possible consequences of a policy, while still placing some weight on better possible consequences. The argument proceeds by elucidating the range of attitudes people can take towards risk, how we must make choices for people when we don’t know their risk-attitudes, and the situation we are in with respect to climate policy and the consequences for future people. The result is an alternative to the Precautionary (...) Principle, an alternative that gives similar policy recommendations in many cases but is also sensitive to the costs of precautions. (shrink)

Some early phase clinical studies of candidate HIV cure and remission interventions appear to have adverse medical risk–benefit ratios for participants. Why, then, do people participate? And is it ethically permissible to allow them to participate? Recent work in decision theory sheds light on both of these questions, by casting doubt on the idea that rational individuals prefer choices that maximise expected utility, and therefore by casting doubt on the idea that researchers have an ethical obligation not to enrol participants (...) in studies with high risk–benefit ratios. This work supports the view that researchers should instead defer to the considered preferences of the participants themselves. This essay briefly explains this recent work, and then explores its application to these two questions in more detail. (shrink)

I have claimed that risk-weighted expected utility maximizers are rational, and that their preferences cannot be captured by expected utility theory. Richard Pettigrew and Rachael Briggs have recently challenged these claims. Both authors argue that only EU-maximizers are rational. In addition, Pettigrew argues that the preferences of REU-maximizers can indeed be captured by EU theory, and Briggs argues that REU-maximizers lose a valuable tool for simplifying their decision problems. I hold that their arguments do not succeed and that my original (...) claims still stand. However, their arguments do highlight some costs of REU theory. (shrink)

This paper examines medical scientists’ accounts of their rediscoveries and reassessments of old materials. It looks at how historical patient files and brain samples of the first cases of Alzheimer’s disease became reused as scientific objects of inquiry in the 1990s, when a genetic neuropathologist from Munich and a psychiatrist from Frankfurt lead searches for left-overs of Alzheimer’s ‘founder cases’ from the 1900s. How and why did these researchers use historical methods, materials and narratives, and why did the biomedical community (...) cherish their findings as valuable scientific facts about Alzheimer’s disease? The paper approaches these questions by analysing how researchers conceptualised ‘history’ while backtracking and reassessing clinical and histological materials from the past. It elucidates six ways of conceptualising history as a biomedical matter: scientific assessments of the past, i.e. natural scientific understandings of ‘historical facts’; history in biomedicine, e.g. uses of old histological collections in present day brain banks; provenance research, e.g. applying historical methods to ensure the authenticity of brain samples; technical biomedical history, e.g. reproducing original staining techniques to identify how old histological slides were made; founding traditions, i.e. references to historical objects and persons within founding stories of scientific communities; and priority debates, e.g. evaluating the role particular persons played in the discovery of a disease such as Alzheimer’s. Against this background, the paper concludes with how the various ways of using and understanding ‘history’ were put forward to re-present historic cases as ‘proto-types’ for studying Alzheimer’s disease in the present.

A basic contradiction in education is that while education and guidance from people with more knowledge is necessary for the development of higher psychological functioning, the constraints imposed on student activity often become a hindrance to development. This contradiction is revealed in how youth participate in video production programs and becomes analyzable because video production brings the conflict to the surface. During video production, students often act with greater agency than they do in other school activities. This shift evokes the (...) agency|structure dialectic as the root of tensions surrounding authority, collaboration, and youth cultures. Based on data from five programs, a comparison of different cases demonstrates how schools damage motivation and initiative, neglect to connect with students and their worlds, and teach passivity while emphasizing an individualistic conception of human activity. New understandings of agency and its connections to the individual|social dialectic are urged. Based on a Vygotskian concept of development as overcoming contradictions, the relationships youth have within school are viewed as an essential part of development, requiring a theoretical shift from individualistic ideas of agency and a clearer connection between youth problems and societal contradictions.

A variety of crucial and still most relevant ideas about nothingness or emptiness have gained profound philosophical prominence in the history and development of a number of South and East Asian traditions--including in Buddhism, Daoism, Neo-Confucianism, Hinduism, Korean philosophy, and the Japanese Kyoto School. These traditions share the insight that in order to explain both the great mysteries and mundane facts about our experience, ideas of "nothingness" must play a primary role. This collection of essays brings together the work of (...) twenty of the world's prominent scholars of Hindu, Buddhist, Daoist, Neo-Confucian, Japanese and Korean thought to illuminate fascinating philosophical conceptualizations of "nothingness" in both classical and modern Asian traditions. The unique collection offers new work from accomplished scholars and provides a coherent, panoramic view of the most significant ways that "nothingness" plays crucial roles in Asian philosophy. It includes both traditional and contemporary formulations, sometimes putting Asian traditions into dialogue with one another and sometimes with classical and modern Western thought. The result is a book of immense value for students and researchers in Asian and comparative philosophy. (shrink)

Existing accounts of the early history of Alzheimer’s disease have focused on Alois Alzheimer’s (1864–1915) publications of two ‘peculiar cases’ of middle-aged patients who showed symptoms associated with senile dementia, and Emil Kraepelin’s (1856–1926) discussion of these and a few other cases under the newly introduced name of ‘Alzheimer’s disease’ in his Textbook of Psychiatry. This article questions the underpinnings of these accounts that rely mainly on publications and describe ‘presenility’ as a defining characteristic of the disease. Drawing on archival (...) research in the Munich psychiatric clinic, in which Alzheimer and Kraepelin practised, this article looks at the use of the category as a diagnostic label in practice. It argues that the first cases only got their exemplary status as key referents of Alzheimer’s disease in later readings of the original publications. In the 1900s, the published cases rather functioned as material to think about the limits of the category of senile dementia. The examination of paper technologies in the Munich psychiatric clinic reveals that the use of the clinical diagnosis of Alzheimer’s disease was not limited to patients of a certain age and did not exclude ‘senile’ cases. Moreover, the archival records reflect that many diagnoses of Alzheimer’s disease were noted in the medical records as suspicions rather than conclusions. Against this background, the article argues that in theory and practice, Alzheimer’s disease was not treated as a well-defined disease entity in the Munich clinic, but as an exploratory category for the clinical and histopathological investigation of varieties of organic brain diseases.

Certain ethical views hold that we should pay more attention, even exclusive attention, to the worst-case scenario. Prominent examples include Rawls's Difference Principle and the Precautionary Principle. These views can be anchored in formal principles of decision theory, in two different ways. On the one hand, they can rely on ambiguity-aversion: the idea that we cannot assign sharp probabilities to various scenarios, and that if we cannot assign sharp probabilities, we should decide pessimistically, as if the probabilities are unfavorable. On (...) the other hand, they can rely on risk-avoidance: the idea that we should pay more attention to worse scenarios, even when we can assign sharp probabilities. I distinguish these two foundations. I also show how they can be modified to support versions of these views that pay more but not exclusive attention to worst-case scenarios. Finally, I argue that risk-avoidance provides a superior foundation than ambiguity-aversion for the Difference Principle and the Precautionary Principle; in particular, it correctly identifies which ethical facts should matter to those who champion these principles.

BACKGROUND: Little is known about how hospitalized patients share decisions with physicians. METHODS: We conducted an observational study of patient-doctor communication on an inpatient medicine service among 18 hospitalized patients and 9 physicians. A research assistant (RA) approached newly hospitalized patients and their physicians before morning rounds and obtained consent. The RA audio recorded morning rounds, and then separately interviewed both patient and physician. Coding was done using integrated analysis. RESULTS: Most patients were white (61%) and half were female. Most (...) physicians were male (66%) and of Southeast Asian descent (66%). All physicians explained the plan of care to the patients; most believed that their patient understood. However, many patients did not. Physicians rarely asked the patient for their opinion. In all those cases, the decision had been made previously by the doctors. No decisions were made with the patient. Patients sometimes disagreed. CONCLUSIONS: Shared decision-making may not be the norm in hospital care. Although physicians do explain treatment plans, many hospitalized patients do not understand enough to share in decisions. When patients do assert their opinion, it can result in conflict. PRACTICE IMPLICATIONS: Some hospitalized patients are interested in discussing treatment. Improving hospital communication can foster patient autonomy. (shrink)

Conceptions of evil have changed dramatically over time, and though humans continue to commit acts of cruelty against one another, today we possess a clearer, more moral way of analyzing them. In _Narrating Evil_, María Pía Lara explores what has changed in our understanding of evil, why the transformation matters, and how we can learn from this specific historical development. Drawing on Immanuel Kant's and Hannah Arendt's ideas about reflective judgment, Lara argues that narrative plays a key role (...) in helping societies acknowledge their pasts. Particular stories haunt our consciousness and lead to a kind of examination and dialogue that shape notions of morality. A powerful description of a crime can act as a filter, helping us to draw conclusions about what constitutes a moral wrong, and public debates over these narratives allow us to construct a more accurate picture of historical truth, leading to a better understanding of why such actions are possible. In building her argument, Lara considers Greek tragedies, Shakespeare's depictions of evil, Joseph Conrad's literary metaphors, and movies that portray human cruelty. Turning to such philosophers and writers as Jürgen Habermas, Walter Benjamin, Primo Levi, Giorgio Agamben, and Ariel Dorfman, Lara defines a reflexive relationship between an event, the narrative of the event, and the public reception of the narrative, and she proves that the stories of perpetrators and sufferers are always intertwined. The process of disclosure, debate, and the public fashioning of collective judgment are vital methods through which we make sense not only of new forms of cruelty but of past crimes as well. _Narrating Evil_ describes the steps of this process and why they are a crucial part of our attempt to build a different, more just world.

Advancements in technology are shifting the ways that biomedical data are collected, managed, and used. The pervasiveness of connected devices is expanding the types of information that are defined as ‘health data.’ Additionally, cloud-based mechanisms for data collection and distribution are shifting biomedical research away from traditional infrastructure towards a more distributed and interconnected ecosystem. This shift provides an opportunity for us to reimagine the roles of scientists and participants in health research, with the potential to more meaningfully engage in (...) partnership across the research process. At the same time, these emerging practices present a potential to expose research participants to unanticipated and unintended consequences. Social norms and policy can help to mitigate these risks, but their development is often slow relative to the pace of technological advances and, as such, they can become reactive rather than prospective. As an alternative, the integrated development of data governance structures within technological advancements, supports their effective implementation, evaluation and evolution in a manner that can balance the benefits and risks of biomedical researcher in a decentralized ecosystem.

My book Risk and Rationality argues for a new alternative to the orthodox theory of rational decision-making. This alternative, risk-weighted expected utility maximization, holds that there are three important components involved in rational decision-making: utilities, probabilities, and risk-attitudes. This essay explains the basic outline of the theory and precisely how it differs from the orthodox theory. It also summarizes the main threads of argument in the book.
