A probability distribution is regular if it does not assign probability zero to any possible event. Williamson argued that we should not require probabilities to be regular, for if we do, certain “isomorphic” physical events must have different probabilities, which is implausible. His remarks suggest an assumption that chances are determined by intrinsic, qualitative circumstances. Weintraub responds that Williamson’s coin flip events differ in their inclusion relations to each other, or the inclusion relations between their times, and this can (...) account for their differences in probability. Haverkamp and Schulz rebut Weintraub, but their rebuttal fails because the events in their example are even less symmetric than Williamson’s. However, Weintraub’s argument also fails, for it ignores the distinction between intrinsic, qualitative differences and relations of time and bare identity. Weintraub could rescue her argument by claiming that the events differ in duration, under a non-standard and problematic conception of duration. However, we can modify Williamson’s example with Special Relativity so that there is no absolute inclusion relation between the times, and neither event has longer duration except relative to certain reference frames. Hence, Weintraub’s responses do not apply unless chance is observer-relative, which is also problematic. Finally, another symmetry argument defeats even the appeal to frame-dependent durations, for there the events have the same finite duration and are entirely disjoint, as are their respective times and places.

This article considers two arguments that purport to show that inductive reasoning is unjustified: the argument adduced by Sextus Empiricus and the (better known and more formidable) argument given by Hume in the Treatise. While Sextus’ argument can quite easily be rebutted, a close examination of the premises of Hume’s argument shows that they are seemingly cogent. Because the sceptical claim is very unintuitive, the sceptical argument constitutes a paradox. And since attributions of justification are theoretical, and the claim that (...) they are never (or seldom) true isn’t preposterous, the correct response to the paradox may well be to admit that the sceptic has exposed our error in making them.

In the twenty-first century, the debate about life on other worlds is quickly changing from the realm of speculation to the domain of hard science. Within a few years, as a consequence of the rapid discovery by astronomers of planets around other stars, astronomers very likely will have discovered clear evidence of life beyond the Earth. Such a discovery of extraterrestrial life will change everything. Knowing the answer as to whether humanity has company in the universe will trigger one of (...) the greatest intellectual revolutions in history, not the least of which will be a challenge for at least some terrestrial religions. Which religions will handle the discovery of extraterrestrial life with ease and which will struggle to assimilate this new knowledge about our place in the universe? Some religions as currently practiced appear to only be viable on Earth. Other religions could be practiced on distant worlds but nevertheless identify both Earth as a place and humankind as a species of singular spiritual religious importance, while some religions could be practiced equally well anywhere in the universe by any sentient beings. Weintraub guides readers on an invigorating tour of the world's most widely practiced religions. It reveals what, if anything, each religion has to say about the possibility that extraterrestrial life exists and how, or if, a particular religion would work on other planets in distant parts of the universe.

The article calls for a departure from the common concept of autonomy in two significant ways: it argues for the supremacy of semantic understanding over procedure, and claims that clinicians are morally obliged to make a strong effort to persuade patients to accept medical advice. We interpret the value of autonomy as derived from the right persons have to respect, as agents who can argue, persuade and be persuaded in matters of utmost personal significance such as decisions about medical care. (...) Hence, autonomy should and could be respected only after such an attempt has been made. Understanding suffering to a significant degree is a prerequisite to sincere efforts of persuasion. It is claimed that a modified and pragmatic form of discourse is the necessary framework for understanding suffering and for compassionately interacting with the frail. (shrink)

General equilibrium analysis is a theoretical structure which focuses research in economics. On this point economists and philosophers agree. Yet studies in general equilibrium analyses are not well understood in the sense that, though their importance is recognized, their role in the growth of economic knowledge is a subject of some controversy. Several questions organize an appraisal of general equilibrium analysis. These questions have been variously posed by philosophers of science, economic methodologists, and historians of economic thought. Is general equilibrium (...) analysis a theory, a paradigm, a scientific research program, or a set of interrelated theories? Is it not any of these but rather a branch of applied mathematics? Is GE analysis associated with the growth of knowledge, or does it waste intellectual resources? How is it related to other work in economics? Is it connected to, or is it apart from, the concerns of applied economists? (shrink)

In this paper I consider the surprise examination paradox from a practical perspective, paying special attention to the communicative role of the teacher’s promise to the students. This perspective, which places the promise within a practice, rather than viewing it in the abstract, imposes constraints on adequate solutions to the paradox. In the light of these constraints, I examine various solutions which have been offered, and suggest two of my own.

Epistemologists have traditionally been concerned with two issues: the justification of particular beliefs or sets of beliefs, and claims to knowledge. I propose to examine the relative import of these questions by comparing the gravity of the threat posed by two sceptics: one who questions the justifiability of our beliefs, and one who doubts our knowledge claims.

ArgumentIn the decades following World War II, the Cowles Commission for Research in Economics came to represent new technical standards that informed most advances in economic theory. The public emergence of this community was manifest at a conference held in June 1949 titledActivity Analysis of Production and Allocation. New ideas in optimization theory, linked to linear programming, developed from the conference's papers. The authors’ history of this event situates the Cowles Commission among the institutions of postwar science in-between National Laboratories (...) and the supreme discipline of Cold War academia, mathematics. Although the conference created the conditions under which economics, as a discipline, would transform itself, the participants themselves had little concern for the intellectual battles that had defined prewar university economics departments. The authors argue that the conference signaled the birth of a new intellectual culture in economic science based on shared scientific norms and techniques un-interrogated by conflicting notions of the meaning of either science or economics.

Many epistemologists agree with the intuition that “there is no exit from the circle of one’s beliefs”. I shall construe this vague intuition as the claim that justification supervenes on the totality of one’s beliefs: two agents with identical beliefs will be indistinguishable with respect to which of their beliefs are justified and to what degree. My central purpose in this paper is to undermine the supervenience thesis. To this end I shall consider the role(s) of the concept of justification.

Rosenberg argues that economists have embraced the methodology of scientific research programs, and the writings of Imre Lakatos, at the same time that philosophers have been abandoning that approach. According to Rosenberg, the methodology of scientific research programs appears to allow some work in economics, which is neither tested nor testable, to be “scientific” nonetheless. That is, MSRP justifies some current practices which look hard to justify on strict falsificationist, or dogmatic positivist, grounds.

This article isolates ten prepositions, which constitute the undercurrent paradigm of contemporary discourse of health disease and medicine. Discussion of the interrelationship between those prepositions leads to a systematic refutation of this paradigm. An alternative set is being forwarded. The key notions of the existing paradigm are that health is the natural condition of humankind and that disease is a deviance from that nature. Natural things are harmonious and healthy while human made artifacts are coercive interference with natural balance. It (...) is suggested that the current paradigm is influenced by the world of finances and by instrumental reason. The alternative model suggests that human nature cannot be delineated. Humans fashion their own selves and nature by artificial means, medicine among them. The article discusses the implications of the paradigm adapted in various scholarly and popular debates such as the use of sex hormones for contraception, the care of the elderly, holistic medicine and distributive justice in health care. Medicine is not an isolated or a privileged realm. There is no unique entitlement to health care. It is always part of a broader agenda of social values and institutions. A open view of human societies, values and practices as they are situated within concrete material conditions is the platform required for an integrative and creative discourse of health care.

Contrary to the common view, this paper suggests that the Hippocratic oath does not directly refer to the controversial subjects of euthanasia and abortion. We interpret the oath in the context of establishing trust in medicine through departure from Pantagruelism. Pantagruelism is coined after Rabelais' classic novel Gargantua and Pantagruel. His satire about a wonder herb, Pantagruelion, is actually a sophisticated model of anti-medicine in which absence of independent moral values and of properly conducted research fashion a flagrant over-medicalization of (...) human problems. Ultimately this undermines the therapeutic core of medicine itself. We contend that PAS is a case of such over-medicalization and that its institution creates medicophobia. This article does not express an opinion about euthanasia in general. Rather, we claim that physicians should learn from the oath and from Rabelais that they should keep their practice to medical care and not to exploit their expertise and social privileges for the sake of ulterior motives, even when their patients desire those goals.

Just over a decade ago, I began teaching medical students in the required preclinical course ethics and professionalism. The point of the course was to introduce basic ethical and professional norms through a small number of large group sessions, but mostly small group tutorials of 10 or 12 students engaging in weekly sessions combining readings from the literature and case scenarios highlighting real-life ethical tensions they either had, or would most likely, encounter in the future. The students wrote perceptively and (...) thoughtfully each week, and class was topical and lively. Some students went on to complete longer essays for a school-wide ethics competition and even to win. By all accounts a resounding... (shrink)

In this paper I adduce a new argument in support of the claim that IBE is an autonomous form of inference, based on a familiar, yet surprisingly, under-discussed, problem for Hume’s theory of induction. I then use some insights thereby gleaned to argue for the claim that induction is really IBE, and draw some normative conclusions.

I defend the suggestion that the rational probability in the Sleeping Beauty paradox is one third. The reasoning in its favour is familiar: for every heads-waking, there are two tails-wakings. To complete the defense, I rebut the reasoning which purports to justify the competing suggestion – that the correct probability is half – by undermining its premise, that no new information has been received.

It is possible that a fair coin tossed infinitely many times will always land heads. So the probability of such a sequence of outcomes should, intuitively, be positive, albeit miniscule: 0 probability ought to be reserved for impossible events. And, furthermore, since the tosses are independent and the probability of heads (and tails) on a single toss is half, all sequences are equiprobable. But Williamson has adduced an argument that purports to show that our intuitions notwithstanding, the probability of an (...) infinite sequence is 0. In this paper, I rebut his argument.No Abstract.

In the inaugural issue of this journal, David Tyfield used some recent discussions about "meaning finitism" to conclude that the sociology of scientific knowledge is an intellectually hopeless basis on which to erect an intelligible study of science. In contrast, the authors show that Tyfield's argument rests on some profound misunderstandings of the SSK. They show that his mischaracterization of SSK is in fact systematic and is based on lines of argument that are at best incoherent.

ABSTRACT Twenty years ago Leif Lewin made the case that altruistic motives are more common than selfish motives among voters, politicians, and bureaucrats. We propose that motives and beliefs emerge as reactions to immediate feedback from technical-causal, material-economic, and moral-social aspects of the political task environment. In the absence of certain kinds of technical-causal and material-economic feedback, moral-social feedback leads individuals to the altruism Lewin documents, but also to righteousness (moralized regard for the in-group and disregard for the out-group) and (...) myopia (disregard for distant consequences). The mix of altruism, righteousness, and myopia increases the focus on winning the next high-stakes election rather than on discovering or enforcing socially productive institutions. (shrink)

What is the nature of the intellectual enterprise - general equilibrium analysis - that so many economists regard as the centerpiece of their discipline? In this book, Roy Weintraub considers both the modern history of the analysis, and the methodological puzzles that it, and mathematical economic theory in general, pose. Professor Weintraub argues that previous writings on the history and method of general equilibrium theory have been curiously biased and misleading. He provides a clear and careful presentation of (...) the development of the theory from the 1930s through to the Arrow-Debreu work of the 1950s. This historical analysis is the centre of the book: a case study which permits the author to justify the status of general equilibrium theory in economics and the activity in which economic theorists engage. He argues that previous methodological investigations have been distorted by their use of inappropriate models taken from the philosophy of science that were developed to appraise work in the physical sciences.

According to conciliatory views about peer disagreement, both peers must accord their disagreeing peer some weight, and move towards him. Non‐conciliatory views allow one peer, the one who responded correctly to the evidence, to remain steadfast. In this paper, I consider the suggestion that it may be rational for both disagreeing peers to hold steadfastly to their opinion. To this end, I contend with arguments adduced against the permissiveness the supposition involves, and identify some ways in which different responses for (...) different agents to the evidence might be reasonable.

Given the growing number of remote and hybrid working arrangements, this research investigates the process and outcomes of proactivity during remote work. We approach proactivity during remote working as a resource-building process and integrate self-leadership and job crafting literature. We propose that employees’ self-leadership allows them to regulate their resources optimally, enabling resource availability that can be used to arrange remote working demands and resources proactively. We collected three-wave data from remote workers and tested our hypotheses using multilevel analyses. Results (...) differed by level of analysis. Specifically, at the between level, comparing behaviors between participants, social expansion mediated the relationship between self-goal setting and task significance. In contrast, at the within level, social expansion mediated the relationship between self-goal setting and work engagement. Overall, these findings suggest that self-leadership allows higher availability of resources enabling the proactive initiation of social interactions, which, at the within level enhance work engagement, and at the between level improve task significance during remote work. We discuss these findings considering the implications for interventions to foster more positive remote-work experiences. (shrink)

Some cognitive processes appear to have “phenomenal” properties that are directly revealed to the subject and not determined by physical properties. I suggest that the source of this appearance is the method by which our brain processes sensory information. The appearance is an illusion. Nonetheless, we are not mistaken when we judge that people sometimes fee lpain.

This paper is not concerned with the (amply discussed) question as to the rational response to peer disagreement. Instead, it addresses a (considerably less often debated) problem to which many views about the (epistemic) significance of disagreement are vulnerable (to some extent or another): self-undermining. I reject several answers that have been proposed in the literature, defend one that has been offered (by meeting objections to it), and show that in its light, the prevalent assumption that the ‘equal-weight view’, a (...) prominent view about disagreement, rationally requires us to suspend judgement about contentious matters, is seen to be too pessimistic.

The lottery paradox shows seemingly plausible principles of rational acceptance to be incompatible. It has been argued that we shouldn’t be concerned by this clash, since the concept of (categorical) belief is otiose, to be supplanted by a quantitative notion of partial belief, in terms of which the paradox cannot even be formulated. I reject this eliminativist view of belief, arguing that the ordinary concept of (categorical) belief has a useful function which the quantitative notion does not serve. I then (...) propose a solution to the paradox it engenders. (shrink)

Do we really know the things we think we know? Are any of our beliefs reasonable? Scepticism gives a pessimistic reply to these important epistemological questions - we don't know anything; none of our beliefs are reasonable. But can such a seemingly paradoxical claim be more than an intellectual curiousity? And if it is, can it be refuted? Ruth Weintraub answers yes to both these questions. The sceptical challenge is a formidable one, and should be confronted, not dismissed. The (...) theoretical and practical difficulties it presents - in that the sceptical life cannot be lived, and the doctrine seems self-defeating - are in fact superficial, according to Ruth Weintraub. Her study looks at the sceptical arguments of Descartes, Hume and the ancient Greek sceptic, Sextus Empiricus. The author argues that by drawing on philosophy, rather than science, the sceptical challenge can be answered. _The Sceptical Challenge_ is a bold and original response to scepticism; it represents a new way of looking at the field for philosophers of epistemology.

The ArgumentIn the minds of many, the Bourbakist trend in mathematics was characterized by pursuit of rigor to the detriment of concern for applications or didactic concessions to the nonmathematician, which would seem to render the concept of a Bourbakist incursion into a field of applied mathematices an oxymoron. We argue that such a conjuncture did in fact happen in postwar mathematical economics, and describe the career of Gérard Debreu to illustrate how it happened. Using the work of Leo Corry (...) on the fate of the Bourbakist program in mathematics, we demonstrate that many of the same problems of the search for a formalstructurewith which to ground mathematical practice also happened in the case of Debreu. We view this case study as an alternative exemplar to conventional discussions concerning the “unreasonable effectiveness” of mathematics in science. (shrink)

In this paper I offer solutions to two problems which our moral practice engenders for expressivism, the meta-ethical doctrine according to which ethical statements aren't propositional, susceptible of truth and falsity, but, rather, express the speaker's non-cognitive attitudes. First, the expressivist must show that arguments which are valid when interpreted propositionally are valid when construed expressivistically, and vice versa. The second difficulty is the Frege-Geach problem. Moral arguments employ atomic sentences, negations, disjunctions, etc., and, by expressivist lights, the meaning of (...) a moral sentence depends on the attitude that it expresses. Since one's attitude varies as one asserts a claim, or negates it, or cites it as a disjunct, etc., the meaning of the relevant phrase changes as well, so the argument equivocates. (Formal proofs are provided in appendices to the paper.). (shrink)
