How can different individuals' probability assignments to some events be aggregated into a collective probability assignment? Classic results on this problem assume that the set of relevant events -- the agenda -- is a sigma-algebra and is thus closed under disjunction (union) and conjunction (intersection). We drop this demanding assumption and explore probabilistic opinion pooling on general agendas. One might be interested in the probability of rain and that of an interest-rate increase, but not in the probability of rain or (...) an interest-rate increase. We characterize linear pooling and neutral pooling for general agendas, with classic results as special cases for agendas that are sigma-algebras. As an illustrative application, we also consider probabilistic preference aggregation. Finally, we compare our results with existing results on binary judgment aggregation and Arrovian preference aggregation. This paper is the first of two self-contained, but technically related companion papers inspired by binary judgment-aggregation theory. (shrink)

How can different individuals' probability functions on a given sigma-algebra of events be aggregated into a collective probability function? Classic approaches to this problem often require 'event-wise independence': the collective probability for each event should depend only on the individuals' probabilities for that event. In practice, however, some events may be 'basic' and others 'derivative', so that it makes sense first to aggregate the probabilities for the former and then to let these constrain the probabilities for the latter. We formalize (...) this idea by introducing a 'premise-based' approach to probabilistic opinion pooling, and show that, under a variety of assumptions, it leads to linear or neutral opinion pooling on the 'premises'. This paper is the second of two self-contained, but technically related companion papers inspired by binary judgment-aggregation theory. (shrink)

Democratic decision-making is often defended on grounds of the ‘wisdom of crowds’: decisions are more likely to be correct if they are based on many independent opinions, so a typical argument in social epistemology. But what does it mean to have independent opinions? Opinions can be probabilistically dependent even if individuals form their opinion in causal isolation from each other. We distinguish four probabilistic notions of opinion independence. Which of them holds depends on how individuals are causally (...) affected by environmental factors such as commonly perceived evidence. In a general theorem, we identify causal conditions guaranteeing each kind of opinion independence. These results have implications for whether and how ‘wisdom of crowds’ arguments are possible, and how truth-conducive institutions can be designed. (shrink)

Suppose several individuals (e.g., experts on a panel) each assign probabilities to some events. How can these individual probability assignments be aggregated into a single collective probability assignment? This article reviews several proposed solutions to this problem. We focus on three salient proposals: linear pooling (the weighted or unweighted linear averaging of probabilities), geometric pooling (the weighted or unweighted geometric averaging of probabilities), and multiplicative pooling (where probabilities are multiplied rather than averaged). We present axiomatic characterisations of each class of (...) pooling functions (most of them classic, but one new) and argue that linear pooling can be justified procedurally, but not epistemically, while the other two pooling methods can be justified epistemically. The choice between them, in turn, depends on whether the individuals' probability assignments are based on shared information or on private information. We conclude by mentioning a number of other pooling methods. (shrink)

We can have credences in an infinite number of propositions—that is, our opinion set can be infinite. Accuracy-first epistemologists have devoted themselves to evaluating credal states with the help of the concept of ‘accuracy’. Unfortunately, under several innocuous assumptions, infinite opinion sets yield several undesirable results, some of which are even fatal, to accuracy-first epistemology. Moreover, accuracy-first epistemologists cannot circumvent these difficulties in any standard way. In this regard, we will suggest a non-standard approach, called a relativistic approach, to accuracy-first (...) epistemology and show that such an approach can successfully circumvent undesirable results while having some advantages over the standard approach.

There are many reasons we might want to take the opinions of various individuals and pool them to give the opinions of the group they constitute. If all the individuals in the group have probabilistic opinions about the same propositions, there is a host of pooling functions we might deploy, such as linear or geometric pooling. However, there are also cases where different members of the group assign probabilities to different sets of propositions, which might overlap a (...) lot, a little, or not at all. There are far fewer proposals for how to proceed in these cases, and those there are have undesirable features. I begin by considering four proposals and arguing that they don't work. Then I'll describe my own proposal, which is intended to cover the situation in which we want to pool the individual opinions in order to ascribe an opinion to the group considered as an agent in its own right.

It is a consequence of the theory of imprecise credences that there exist situations in which rational agents inevitably become less opinionated toward some propositions as they gather more evidence. The fact that an agent's imprecise credal state can dilate in this way is often treated as a strike against the imprecise approach to inductive inference. Here, we show that dilation is not a mere artifact of this approach by demonstrating that opinion loss is countenanced as rational by a substantially (...) broader class of normative theories than has been previously recognised. Specifically, we show that dilation-like phenomena arise even when one abandons the basic assumption that agents have (precise or imprecise) credences of any kind, and follows directly from bedrock norms for rational comparative confidence judgements of the form `I am at least as confident in p as I am in q'. We then use the comparative confidence framework to develop a novel understanding of what exactly gives rise to dilation-like phenomena. By considering opinion loss in this more general setting, we are able to provide a novel assessment of the prospects for an account of inductive inference that is not saddled with the inevitability of rational opinion loss.

In this paper, I reply to Seidel’s objections against my argument from expert performance to the effect that arguments from expert opinion are weak arguments. I clarify what Seidel takes to be unclear points in my argument and show that it withstands Seidel’s objections.

Accounts of arguments from expert opinion take it for granted that expert judgments count as (defeasible) evidence for propositions, and so an argument that proceeds from premises about what an expert judges to a conclusion that the expert is probably right is a strong argument. In Mizrahi (2013), I consider a potential justification for this assumption, namely, that expert judgments are significantly more likely to be true than novice judgments, and find it wanting because of empirical evidence suggesting that expert (...) judgments under uncertainty are not significantly more likely to be true than novice judgments or even chance. In this paper, I consider another potential justification for this assumption, namely, that expert judgments are not influenced by the cognitive biases novice judgments are influenced by, and find it wanting, too, because of empirical evidence suggesting that experts are vulnerable to pretty much the same cognitive biases that novices are vulnerable to. If this is correct, then the basic assumption at the core of accounts of arguments from expert opinion, namely, that expert judgments count as (defeasible) evidence for propositions, remains unjustified.

Spatially situated opinions that can be held with different degrees of conviction lead to spatiotemporal patterns such as clustering (homophily), polarization, and deadlock. Our goal is to understand how sensitive these patterns are to changes in the local nature of interactions. We introduce two different mixing mechanisms, spatial relocation and nonlocal interaction (“telephoning”), to an earlier fully spatial model (no mixing). Interestingly, the mechanisms that create deadlock in the fully spatial model have the opposite effect when there is a (...) sufficient amount of mixing. With telephoning, not only is polarization and deadlock broken up, but consensus is hastened. The effects of mixing by relocation are even more pronounced. Further insight into these dynamics is obtained for selected parameter regimes via comparison to the mean-field differential equations. (shrink)

Opinions are rarely binary; they can be held with different degrees of conviction, and this expanded attitude spectrum can affect the influence one opinion has on others. Our goal is to understand how different aspects of influence lead to recognizable spatio-temporal patterns of opinions and their strengths. To do this, we introduce a stochastic spatial agent-based model of opinion dynamics that includes a spectrum of opinion strengths and various possible rules for how the opinion strength of one individual (...) affects the influence that this individual has on others. Through simulations, we find that even a small amount of amplification of opinion strength through interaction with like-minded neighbors can tip the scales in favor of polarization and deadlock.

At the heart of Mizrahi’s project lies a sociological narrative concerning the recent history of philosophers’ negative attitudes towards scientism. Critics (e.g. de Ridder (2019), Wilson (2019) and Bryant (2020)), have detected various empirical inadequacies in Mizrahi’s methodology for discussing these attitudes. Bryant (2020) points out one of the main pertinent methodological deficiencies here, namely that the mere appearance of the word ‘scientism’ in a text does not suffice in determining whether the author feels threatened by it. Not all philosophers (...) use the term in ‘inherently negative’ (29) or pejorative ways. In this paper, I not only corroborate Bryant’s critical claim, but argue that Mizrahi’s response to this part of Bryant’s objection is inadequate. (shrink)

In this paper, I investigate the role of public opinion and De Staël’s liberal principles in relation to her psychological image of human nature. De Staël regarded the French Revolution as a new stage of human progress, in which the French people, for the first time, gained a political voice. From her position as a liberal republican, De Staël argues for political progress in the form of civil equality and liberty confirmed by law and political representation, for which public opinion (...) serves as a political tool. I aim to demonstrate that De Staël developed a multi-layered analysis of public opinion as both an emancipatory tool for more equality, justice, and liberty, as well as a discriminating and harmful tool. According to De Staël, human passions play a crucial role in determining the employment and the effects of public opinion, as becomes clear in the case of the trial of Marie-Antoinette. (shrink)

Election prediction by means of opinion polling is a rare empirical success story for social science. I examine the details of a prominent case, drawing two lessons of more general interest: Methodology over metaphysics. Traditional metaphysical criteria were not a useful guide to whether successful prediction would be possible; instead, the crucial thing was selecting an effective methodology. Which methodology? Success required sophisticated use of case-specific evidence from opinion polling. The pursuit of explanations via general theory or causal mechanisms, by (...) contrast, turned out to be precisely the wrong path—contrary to much recent philosophy of social science. (shrink)

This chapter provides a systematic overview of topological explanations in the philosophy of science literature. It does so by presenting an account of topological explanation that I (Kostić and Khalifa 2021; Kostić 2020a; 2020b; 2018) have developed in other publications and then comparing this account to other accounts of topological explanation. Finally, this appraisal is opinionated because it highlights some problems in alternative accounts of topological explanations, and also it outlines responses to some of the main criticisms raised by the (...) so-called new mechanists.

In times of populist mistrust towards experts, it is important and the aim of the paper to ascertain the rationality of arguments from expert opinion and to reconstruct their rational foundations as well as to determine their limits. The foundational approach chosen is probabilistic. However, there are at least three correct probabilistic reconstructions of such argumentations: statistical inferences, Bayesian updating, and interpretive arguments. To solve this competition problem, the paper proposes a recourse to the arguments' justification strengths achievable in the (...) respective situation. (shrink)

This essay provides an opinionated survey of some recent developments in the literature on ontological dependence. Some of the most popular definitions of ontological dependence are formulated in modal terms; others in non-modal terms (e.g., in terms of the explanatory connective, ‘because’, or in terms of a non-modal conception of essence); some (viz., the existential construals of ontological dependence) emphasise requirements that must be met in order for an entity to exist; others (viz., the essentialist construals) focus on conditions that (...) must be satisfied in order for an entity to be the very entity it is at each time at which it exists; some are rigid, in the sense that they concern a relation between particular entities; others are generic, in the sense that they involve only a relation between an entity and some entities or other, which bear certain characteristics. I identify three potential measures of success with respect to which these different definitions of ontological dependence can be evaluated and consider the question of how well they in fact meet these desiderata. I end by noting that certain challenges face even the most promising essentialist construals of ontological dependence. (shrink)

Expert testimony figures in recent debates over how best to understand the norm of assertion and the domain-specific epistemic expectations placed on testifiers. Cases of experts asserting with only isolated second-hand knowledge (Lackey 2011, 2013) have been used to shed light on whether knowledge is sufficient for epistemically permissible assertion. I argue that relying on such cases of expert testimony introduces several problems concerning how we understand expert knowledge, and the sharing of such knowledge through testimony. Refinements are needed to (...) clarify exactly what principles are being tested by such cases; but once refined, such cases raise more questions than they answer. (shrink)

This paper contributes to the project of articulating and defending the supra-Bayesian approach to judgment aggregation. I discuss three cases where a person is disposed to defer to two different experts, and ask how they should respond when they learn about the opinion of each. The guiding principles are that this learning should go by conditionalisation, and that they should aim to update on the evidence that the expert had updated on. But this doesn’t settle how the update on pairs (...) of experts should go, because we also need to know how the experts are related. I work through three examples showing how the results change given different prior beliefs about this relationship. (shrink)

Universities seeking to provide modern education face a constant need to update their courses. This study was conducted to collect and analyze empirical data to help philosophy course designers consider the views of Ukrainian students about effective ways to learn this subject. A survey was conducted among 40 humanities students and 34 social science students to determine participants’ views on a number of key issues related to the organization of the learning process in the Philosophy course. Most of the students (...) surveyed said that of the types of skills and knowledge that can be acquired during the course, they will find critical thinking skills and the skills needed to build and argue their own positions on ethical, social and worldview issues most valuable in their future professional activities. The majority of respondents named traditional lectures and discussions of lecture videos as their preferred forms of learning philosophy. Their preferred forms of assessment of students’ knowledge and skills in philosophy were essays, as well as reports and participation in the discussion during practical lessons. The study also identified three significant differences in the responses of the surveyed humanities and social science students. First, socio-scientific students valued the opportunity to develop their communication skills in the framework of the Philosophy course significantly more than humanities students. Second, humanities students included thought experiments among the most desirable ways of learning philosophy, unlike social science students, who included case studies. Third, in contrast to humanities students, social science students considered quizzes to be one of the best forms of assessment for the course. In addition to the above, this study also compared the data on the opinions of social sciences and humanities students with the results of the previous survey of 60 STEM students about their thoughts on the course. The comparative analysis revealed five common features and two significant differences in the responses of students from these three fields of knowledge. The common belief among surveyed students in all three groups is that learning philosophy can provide them with the skills and knowledge they will need in their professional activities after graduation from university. Moreover, they prefer skills to knowledge. In all three groups of respondents, a large number of students named critical thinking and argumentation skills as the ultimate achievements in the learning of philosophy. Another finding was that surveyed students from all three groups do not give priority to learning the concepts of modern philosophers over learning the ideas of ancient philosophers. In addition, respondents from all three fields showed the least interest in those forms of knowledge and skills that are difficult to use outside of highly specialized philosophical activities. As for the differences, the study showed that STEM students are significantly less likely to believe that they will need the historico-philosophical components of the Philosophy course in their further professional activities than students in the humanities and social sciences. They are also more interested in developing communicative skills in the process of learning philosophy than the surveyed humanities students. (shrink)

There is, in some quarters, concern about high–level machine intelligence and superintelligent AI coming up in a few decades, bringing with it significant risks for humanity. In other quarters, these issues are ignored or considered science fiction. We wanted to clarify what the distribution of opinions actually is, what probability the best experts currently assign to high–level machine intelligence coming up within a particular time–frame, which risks they see with that development, and how fast they see these developing. We (...) thus designed a brief questionnaire and distributed it to four groups of experts in 2012/2013. The median estimate of respondents was for a one in two chance that high-level machine intelligence will be developed around 2040-2050, rising to a nine in ten chance by 2075. Experts expect that systems will move on to superintelligence in less than 30 years thereafter. They estimate the chance is about one in three that this development turns out to be ‘bad’ or ‘extremely bad’ for humanity. (shrink)

It is often suggested that when opinions differ among individuals in a group, the opinions should be aggregated to form a compromise. This paper compares two approaches to aggregating opinions, linear pooling and what I call opinion agglomeration. In evaluating both strategies, I propose a pragmatic criterion, No Regrets, entailing that an aggregation strategy should prevent groups from buying and selling bets on events at prices regretted by their members. I show that only opinion agglomeration is able (...) to satisfy the demand. I then proceed to give normative and empirical arguments in support of the pragmatic criterion for opinion aggregation, and that ultimately favor opinion agglomeration. (shrink)

The paper addresses an exegetical puzzle that is raised by Kant's distinction between opining (Meinen), believing (Glauben), and knowing (Wissen). In presenting his moral arguments, Kant often points out that belief, as he conceives of it, has a unique feature: it requires non-epistemic justification. Yet Kant's official formulation of the tripartite distinction runs counter to this claim. It describes Belief in terms of a set of two features, each of which also pertains to either opinion or knowledge. My aim in (...) this paper is to propose a novel interpretation of Kant’s distinction which dissolves this exegetical puzzle. (shrink)

Many students struggle to enter moral debates in a productive way because they automatically think of moral claims as ‘just opinions’ and not something one could productively argue about. Underlying this response are various versions of a muddled distinction between ‘facts’ and ‘opinions.’ This paper outlines a way to help students overcome their use of this distinction, thereby clearing an obstacle to true moral debate. It explains why the fact-opinion distinction should simply be scrapped, rather than merely sharpened. (...) It then proposes a different distinction well suited to replace it. Finally, it outlines an activity which can be used to teach the new distinction, as well as a number of benefits to attempting the whole replacement process. (shrink)

This paper discusses the contrast between scientific knowledge and opinion as it is presented by Aristotle in Posterior Analytics A.33. Aristotle's contrast is formulated in terms of understanding or not understanding some "necessary items". I claim that the contrast can only be understood in terms of explanatory relevance. The "necessary items" are middle terms (or explanatory factors) that are necessary for the fully appropriate explanation. This approach gives a coherent interpretation of each step in the chapter.

In this paper, I will try to answer the question: How are we supposed to assess the expert’s opinion in an argument from the position of an outsider to the specialized field? by placing it in the larger context of the political status of epistemic authority. In order to do this I will first sketch the actual debate around the problem of expertise in a democracy and relate this to the issue of the status of science in society. Secondly, I (...) will review how Douglas Walton’s pragma-dialectical approach offers a practical procedure to assess the expert bias from a nonprofessional’s perspective. Thirdly, I will introduce the problem of group bias using insights from Bohman and Fischer and show how Walton’s solution does not address this specific type of bias. Lastly, I will try proposing a revision of Walton’s solution in order to address this problem. In order to make the explanation more easy to follow I will use a case study concerning the medical expertise in the public debate on second-hand smoke. (shrink)

When does opinion formation within an interacting group lead to consensus, polarization or fragmentation? The article investigates various models for the dynamics of continuous opinions by analytical methods as well as by computer simulations. Section 2 develops within a unified framework the classical model of consensus formation, the variant of this model due to Friedkin and Johnsen, a time-dependent version and a nonlinear version with bounded confidence of the agents. Section 3 presents for all these models major analytical results. (...) Section 4 gives an extensive exploration of the nonlinear model with bounded confidence by a series of computer simulations. An appendix supplies needed mathematical definitions, tools, and theorems. (shrink)

Introduction: Anatomy education known as being among the most significant components of medical education exists in the first and second semester lecture contents of medicine faculties. The considering of medicine faculty students viewpoints about anatomy education is important for improving anatomy education and teaching methods. In addition, the evaluation of interest and awareness of students to anatomy in postgraduate specialization preferences provides to predict researcher number which will be study in this area. -/- Materials and Methods: In this study, it (...) was proposed to evaluate the opinions of medicine faculty students about anatomy education and the view points and the awareness to anatomy in postgraduate specialization education. This study was performed on Gaziantep University second and third year medicine faculty students (n= 340). The data were obtained by feedback method with a questionnaire which consist of 30 question. -/- Results: It was found that the students chiefly benefited from lecture notes while they have been studied to theoretical and practical part of the anatomy individually. No significant correlation was found among general average grade and lengths of anatomy study of students (r= 0.097, p= 0.074). Fifty percent (%50) of students thought that don’t use of cadaver is always a deficiency in anatomy education. It was seen that the postgraduate career preferences of the students of 39.4% was internal medicine departments. The rate of students desiring the postgraduate anatomy specialization education was 1.2%. -/- Conclusion: In conclusion, the achieved results may will be beneficial for improving the new educational strategies related anatomy, resolving the present deficiencies and increasing the tendency to postgraduate anatomy education.

John Stuart Mill advocated for increased interactions between individuals of dissenting opinions for the reason that it would improve society. Whether Mill and similar arguments that advocate for opinion diversity are valid depends on background assumptions about the psychology and sociality of individuals. The field of opinion dynamics is a burgeoning testing ground for how different combinations of sociological and psychological facts contribute to phenomena that affect opinion diversity, such as polarization. This paper applies some recent results from the (...) opinion dynamics literature to assess the impacts of the Millian suggestion. The goal is to understand how the scope of the validity of Mill-style arguments depends on plausible assumptions that can be formalized using agent-based models, a common modeling approach in opinion dynamics. The most salient insight is that homophily (increased interactions between like-minded individuals) does not sufficiently explain decreased opinion diversity. Hence, decreasing homophily by increasing interactions between individuals of dissenting opinions is not the simple solution that a Millian-style argument may advocate. (shrink)

Attitude verbs like ‘believe’ and ‘want’ exhibit neg-raising: an ascription of the form a doesn’t believe that p tends to convey that a disbelieves—i.e., believes the negation of—p. In ‘Belief is Weak’, Hawthore et al. observe that neg-raising does not occur with verbs like ‘know’ or ‘need’. According to them, an ascription of the form a believes that p is true just in case a is in a belief state that makes p more likely than not, and so—excepting cases of (...) complete indifference—a will either believe p or disbelieve p. I expand and revise this explanation: so-called ‘weak’ attitude verbs are used in ascriptions of an opinion about some subject matter S—a kind of selection from among the elements of S—and these ascriptions are themselves responsive to conversational topics that presuppose that the subject of the ascription has an opinion about S. ‘Strong’ attitude verbs denote more direct relationships between subject and world.

In “The Fixation of Belief,” Peirce apparently accepts the causal claim that real physical objects cause us to reach an indefeasible “final opinion” concerning them. In “How to Make Our Ideas Clear,” he apparently accepts the constitutive claim that for physical objects to be real just is for them to be represented in that opinion. These claims initially seem inconsistent, since causal claims are explanatory and since equivalent claims cannot explain one another. Contrary to prominent suggestions that Peirce rejected the (...) constitutive claim, however, he actually accepted both, reconciling them via a Humean denial that causal claims are genuinely explanatory.

Merging of opinions results underwrite Bayesian rejoinders to complaints about the subjective nature of personal probability. Such results establish that sufficiently similar priors achieve consensus in the long run when fed the same increasing stream of evidence. Initial subjectivity, the line goes, is of mere transient significance, giving way to intersubjective agreement eventually. Here, we establish a merging result for sets of probability measures that are updated by Jeffrey conditioning. This generalizes a number of different merging results in the (...) literature. We also show that such sets converge to a shared, maximally informed opinion. Convergence to a maximally informed opinion is a (weak) Jeffrey conditioning analogue of Bayesian “convergence to the truth” for conditional probabilities. Finally, we demonstrate the philosophical significance of our study by detailing applications to the topics of dynamic coherence, imprecise probabilities, and probabilistic opinion pooling. (shrink)

This work treats the correlative concepts knowledge and opinion, in various senses. In all senses of ‘knowledge’ and ‘opinion’, a belief known to be true is knowledge; a belief not known to be true is opinion. In this sense of ‘belief’, a belief is a proposition thought to be true—perhaps, but not necessarily, known to be true. All knowledge is truth. Some but not all opinion is truth. Every proposition known to be true is believed to be true. Some but (...) not every proposition believed to be true is known to be true. Our focus is thus on propositional belief (“belief-that”): the combination of propositional knowledge (“knowledge-that”) and propositional opinion (“opinion-that”). Each of a person’s beliefs, whether knowledge or opinion, is the end result of a particular thought process that continued during a particular time interval and ended at a particular time with a conclusive act—a judgment that something is the case. This work is mainly about beliefs in substantive informative propositions—not empty tautologies. We also treat objectual knowledge (knowledge of objects in the broadest sense, or “knowledge-of”), operational knowledge (abilities and skills, “knowledge-how-to”, or “know-how”), and expert knowledge (expertise). Most points made in this work have been made by previous writers, but to the best of our knowledge, they have never before been collected into a coherent work accessible to a wide audience. -/- Key words: belief, knowledge/opinion, propositional, operational, objectual, cognition, .

In this paper, we examine how a research institution’s social structure and academic opinion leaders’ presence shaped the early adoption of a scientific innovation. Our case considers the early engagement of mathematical economists at the Cowles Commission with John von Neumann and Oskar Morgenstern’s Theory of Games and Economic Behavior. We argue that scholars with administrative leadership functions who were not only scientifically but also organizationally central – in our case the director of research Jacob Marschak – played a crucial (...) role in promoting the adoption of the Theory of Games. We support our argument with a scientometric analysis of all acknowledgments made in 488 papers published from 1944 to 1955 in the two main paper series at Cowles. We apply blockmodeling techniques to the acknowledgments network to reconstruct the formal and informal social structure at Cowles at the time. Our findings suggest that studies of the early adoption of scientific theories benefit from complementary perspectives on the role of academic leaders and scientists. Our study reveals the importance of formal and informal social structures and the agenda of administrative leaders in these structures to explain their adoption. (shrink)

Clinical Ethics Consultations are an important tool for physicians in solving difficult cases. They are extremely common in North America and to a lesser extent also present in Europe. However, there is little data on this practice in Poland. We present results of a survey of 521 physicians practising in Poland concerning their opinion on CECs and related practices. We analysed the data looking at such issues as CECs’ perceived availability, use of CECs, and perceived usefulness of such support. Physicians (...) in our study generally encounter hard ethics cases, even—surprisingly—those who do not work in hospitals. Most physicians have no CEC access, and those that do still do not employ CECs. However, physicians perceive this form of support as useful—even more so among actual users of CECs. We compared these findings with similar studies from other European countries and the North America. We point out peculiarities of our results as compared to those in other countries, with some possible explanations. We hope the results may encourage regulatory debate on the need to formally introduce CECs into the Polish healthcare system. (shrink)

Morphological Computation is based on the observation that biological systems seem to carry out relevant computations with their morphology (physical body) in order to successfully interact with their environments. This can be observed in a whole range of systems and at many different scales. It has been studied in animals – e.g., while running, the functionality of coping with impact and slight unevenness in the ground is "delivered" by the shape of the legs and the damped elasticity of the muscle-tendon (...) system – and plants, but it has also been observed at the cellular and even at the molecular level – as seen, for example, in spontaneous self-assembly. The concept of morphological computation has served as an inspirational resource to build bio-inspired robots, design novel approaches for support systems in health care, implement computation with natural systems, but also in art and architecture. As a consequence, the field is highly interdisciplinary, which is also nicely reflected in the wide range of authors that are featured in this e-book. We have contributions from robotics, mechanical engineering, health, architecture, biology, philosophy, and others. (shrink)

There is a well-known equivalence between avoiding accuracy dominance and having probabilistically coherent credences (see, e.g., de Finetti 1974, Joyce 2009, Predd et al. 2009, Pettigrew 2016). However, this equivalence has been established only when the set of propositions on which credence functions are defined is finite. In this paper, I establish connections between accuracy dominance and coherence when credence functions are defined on an infinite set of propositions. In particular, I establish the necessary results to extend the classic accuracy (...) argument for probabilism to certain classes of infinite sets of propositions including countably infinite partitions.

For the past few years in the United States, almost daily there’s a headline about new proposed abortions restrictions. Conservatives cheer, liberals despair. But who is right here? Should abortion be generally legal or should it be banned? Is it usually immoral or is it usually not wrong at all? These same questions, of course, are asked in other countries. To many people, answers to these questions seem obvious, and people with different or contrary answers are, well, just wrong. But (...) how can we know? In particular, could anyone know that abortion is not wrong and should be legal? If so, how? And how would anyone effectively, persuasively, communicate that knowledge? One important set of answers depends on this idea: critical thinking. Critical thinking can help people know, not merely believe or feel, that their perspectives on issues are true or correct, and it can help them persuade others to understand and accept that knowledge. We are philosophy professors who teach courses in critical thinking and its applications to ethical, political, scientific, and legal issues. In our 2019 open-access book, Thinking Critically About Abortion: Why Most Abortions Aren’t Wrong & Why All Abortions Should be Legal, we apply well-confirmed methods of critical thinking to the most discussed arguments about abortion. Critical thinking can be operationalized as skills. Three key critical thinking skills involve defining words, identifying the structures of arguments, and evaluating explanations. Understanding these and other critical thinking skills can only help improve conversations and advocacy about abortion. Let’s see them in action. (shrink)

Bioethicists’ views diverge public opinion on various ethical issues, particularly in healthcare. For instance, bioethicists generally oppose payment for organs and advocate for preventing death at any age, whereas the public is more supportive of organ payment and prioritizing younger patients. I offer four arguments on how best to view this divergence. (a) Bioethicists’ specialized training, objectivity, and reliance on research often lead to views that differ from those of the public, which may be less informed and more influenced by (...) biases. (b) Further, divergence between expert and public opinion is a normal and sometimes necessary aspect of bioethics. Divergence can lead to more informed and progressive ethical practices. (c) While public input is valuable, achieving meaningful engagement is difficult due to varying values, risk perceptions, and socioeconomic circumstances. Effective bioethics would balance expert knowledge with public input, aiming for policies that are both scientifically sound and democratically legitimate. (d) Maintaining public trust in bioethics does not require full alignment with public opinion. Instead, bioethicists should focus on educating the public and incorporating informed public perspectives into their analysis and recommendations. (shrink)

In this article, I address some central issues in journalism ethics from a fresh perspective, namely, one that is theoretical and informed by values salient in sub-Saharan Africa. Drawing on a foundational moral theory with an African pedigree, which is intended to rival Western theories such as Kantianism and utilitarianism, I provide a unified account of an array of duties of various agents with respect to the news/opinion media.

Mechanisms for QoS provisioning in communication networks range from flow-based resource reservation schemes, providing QoS guarantees, through QoS differentiation based on reservation aggregation techniques to adaptation of applications, compensating for incomplete reservations.

Adaptation is particularly important in wireless networks, where reservations schemes are more difficult to realize. It is widely accepted that usability of Cellular or Mobile IP can be largely improved if (...) adaptation is incorporated. Adaptation, in turn, depends on coding techniques involved and on user requirements. Those impose certain preferences and ordering relations on QoS hierarchies or degradation paths to be followed along when adaptation is performed. With the advent of MPEG4 coding techniques, more sophisticated adaptation schemes are more likely to be supported in the future. (shrink)

Abstract: To improve the countries’ pharmaceutical situation and to monitor the progress, the World Health Organization (WHO) and member states developed a system of indicators to measure the respective important aspects as a prerequisite step. Level I indicators to assess the country’s pharmaceutical situation include the national drug policy; legislation and regulations; drug accessibility and affordability; essential drug list; quality control; pharmacovigilance; storage and distribution; information and rational use. This study is aimed to document the professional opinion of 20 pharmacy (...) practice professionals on Libya’s current pharmaceutical situation, utilizing WHO indicator-based approach. The core indicators measure the most important information needed to understand the pharmaceutical situation in a country. A closed-end questionnaire was distributed to ten practicing pharmacists and ten pharmacy teaching staff members who practice pharmacy. The questionnaires were handed over personally and collected on the same day. The responses were analyzed using simple statistics. The results were argued in the light of the first author’s observation and view, being expert in this field, with reference to the other experts’ views, relevant publications’ findings and WHO reports’ conclusions on these indicators. Suggestions and recommendations for a proper situation assessment, planning and action taking are presented. Primarily, government’s commitment towards appropriate restructuring, management and monitoring of the pharmaceutical sector is crucial. That is to enhance the country’s pharmaceutical situation, to provide and sustain efficient pharmaceutical services and to improve the overall health care system’s performance. (shrink)

I hold profound respect for all individuals, regardless of gender, race, sexual orientation, or any other characteristic, advocating strongly for equality and equity worldwide. Throughout my career as a scientist, I have demonstrated this respect, including for female students and colleagues, supporting them with recommendations and accolades. I have always cherished diversity in my academic and professional circles and I hugely value the contributions of women like Marie Curie and Maryam Mirzakhani, as well as authors such as Agatha Christie and (...) J.K. Rowling. In my personal life, I express my love and admiration for my girlfriend through poetry and gestures, while also honoring my parents, especially my mother, who instilled in me a deep respect for all individuals. Raised in a family that values and respects women, I have been positively impacted by my mother, a retired teacher, and my father, a novelist who often portrays the life of Turkmen women in his works. Overall, my commitment to respecting and valuing all individuals, regardless of their background or identity, remains unwavering. (shrink)

Although certain recent developments in mendacious political manipulation of public discourse are horrifying to the academic mind, I argue that we should not panic. Charles Peirce’s pragmatist epistemology with its teleological arc, long horizon, and rare balance between robust realism and contrite fallibilism offers guidance to weather the storm, and perhaps even see it as inevitable in our intellectual development. This paper explores Peirce’s classic “four methods of fixing belief”, which takes us on an entertaining and still very pertinent tour (...) through tenacity, authority and a priori speculation to the method of science – the only method which is both public and self-correcting. Although in the West we (mostly) proudly self-conceive as living in a ‘scientific age’, I argue that this is premature. Precisely insofar as we treat the misbehavior of governments as a harbinger of doom, we remain trapped in authoritarian modes of thinking which Peirce identified with medievalism, although modernity is increasingly quickening around us in worldwide information-sharing practices that are shaped entirely by mutual help. With this framework in mind, many tactics of recent media are most helpfully seen as belonging not to a post-truth, but a pre-truth stage of human intellectual development. Advice on this is sought from Plato, who of course also faced a world that was ‘pre-academic’. (shrink)

I propose the notion of ‘epistemic sanity’, a property of parsimony between the holding of true but not false beliefs and the consideration of our cognitive limitations. Where ‘alethic value’ is the epistemic value of holding true but not false beliefs, the ‘alethic potential’ of an agent is the amount of extra alethic value that she is expected to achieve, given her current environment, beliefs, and reasoning skills. Epistemic sanity would be related to the holding of (true or false) beliefs (...) that increase the agent's alethic potential (relevant beliefs) but not of beliefs that decrease it (this is related to cognitive parsimony). Suspension of judgment, forgetting, and clutter avoidance are the main contributors to an agent's epistemic sanity, where this paper focuses on suspension. I argue that rational suspension favors the holding of true and relevant beliefs, which is not the case for the extremes of opinionation (no suspension) and skepticism (general suspension). In the absence of evidence, opinionated agents are often forced to rely on principles such as the principle of indifference, but suspension dominates indifference in terms of alethic value in some conditions. A rational agent would only find it beneficial to adopt skepticism if she considers herself to be an anti-expert about her entire agenda, but then ‘flipping’ beliefs maximizes expected alethic value in relation to skepticism. The study of epistemic sanity results in an ‘impure’ veritism, which can deal with some limitations of veritism (e.g., explaining the existence of false but relevant beliefs). (shrink)

The aim of this paper is to clarify the role of the distinction between belief and opinion in the light of Dennett's intentional stance. In particular, I consider whether the distinction could be used for a defence of the stance from various criticisms. I will then apply the distinction to the so-called `paradoxes of irrationality'. In this context I will propose that we should avoid the postulation of `boundaries' or `gaps' within the mind, and will attempt to show that a (...) useful treatment of the paradoxes can be obtained by revising the rationality assumption.

This research aims to contribute to the discussion on the subject of Abortion by analyzing the concepts of formed and unformed in the Septuagint in Exodus 21:22-23, and the opinions of St. Augustine and St. Thomas Aquinas on the social status of the fetus. The Greek version of the Hebrew Bible, which was translated in stages into Greek between the 3rd century BC and the 1st century BC, presents a different point of view than that found in the Hebrew (...) text of Exodus 21:22-23. It introduces the notions of formed and unformed fetus. In other words, he understood the fetus (embryo) in a perspective of developing reality. Augustine and Aquinas, two important names in Christian theology, seem to have reflected a tradition that granted protection to the unborn child according to the stages of its development. The discussion around the topic of abortion is complex, very sensitive, but it should not be avoided. Bibliographical research was used as methodology. As a result, it will be pointed out that the biblical presentation of human beings does not begin with an explanation of conception or the fetal period. It does not discuss the point at which the embryo attains the full moral status of a human person. Thus, for this research, the discussion about abortion must necessarily take into account issues such as risk to the pregnant woman's life; fetal malformation etc. But, above all, it must be centered on the personality of the pregnant woman.
