Coronary arteries were studied on 110 postmortem human hearts during January 2000 to December 2001 in the department of Anatomy and Microbiology, Bangladesh Medical College to observed. The pattern of coronary dominance and its relation with atherosclerosis was observed. Atherosclerosis was found in 49(44.5%) samples, among which 37(56.%) were from male and 12(26.7%) from female hearts. This difference was significant (P<0.01). Right dominance was observed in 72 (65.5%) cases while 17 (15.5%) had left dominance and 21 (19.1%) had balanced type (...) of circulation. Balanced type of circulation was observed more among females (14; 66.7%) while left dominance was more frequent among males (13; 76.5 %). This deference on the basis of sex was significant (P<0.05). Significant (P<0.001) relationship was also observed between atherosclerosis and dominance of coronary artery. It may be concluded that atherosclerosis was present in almost half of the studied subjects and was found more among males. Left dominance was more frequently present among males it was associated with atherosclerosis. (shrink)

This paper aims to introduce a robust framework for forecasting demand, including data preprocessing, data transformation and standardization, feature selection, cross-validation, and regression ensemble framework. Bagging ), boosting and extreme gradient boosting regression ), and stacking are employed as ensemble models. Different machine learning approaches, including support vector regression, extreme learning machine, and multilayer perceptron neural network, are adopted as reference models. In order to maximize the determination coefficient value and reduce the root mean square error, hyperparameters are set using (...) the grid search method. Using a steel industry dataset, all tests are carried out under identical experimental conditions. In this context, STACK1 and STACK2 models provided better performance than other models. The highest accuracies of R2 of 0.97 and 0.97 are obtained using STACK1 and STACK2, respectively. Moreover, the rank according to performances is STACK1, STACK2, XGBR, GBR, RFR, MLP, ELM, and SVR. As it improves the performance of models and reduces the risk of decision-making, the ensemble method can be used to forecast the demand in a steel industry one month ahead. (shrink)

Central to the particularist project, one that has become the consensus in the philosophy of conspiracy theory theory, is the claim that a general dismissal of these things called `conspiracy theories' is unsustainable. That is, if we want to say a conspiracy theory is suspicious such that we should not believe it, then we have to engage in at least some investigation of it. Particularists have detailed just why a general attitude of skepticism towards conspiracy theories is implausible; they have, (...) in effect, created the case against generalism. The case for particularism, then, has largely been about challenging and rebutting generalist arguments. But what of the bigger picture? If particularists argue that we should not assume conspiracy theories are mad, bad, or dangerous but, rather, investigate them, then how should we go about that investigation? In this paper I describe (some) of the preliminary concerns the particularist (and the generalist) needs to account for when developing an ethics of investigation into these things called `conspiracy theories.' Whilst this paper does not provide a framework for the investigation of conspiracy theories, it provides the framework for such a framework. (shrink)

A remarkable feature of the philosophical work on conspiracy theory theory has been that most philosophers agree there is nothing inherently problematic about conspiracy theories (AKA the thesis of particularism). Recent work, however, has challenged this consensus view, arguing that there really is something epistemically wrong with conspiracy theorising (AKA generalism). Are particularism and generalism incompatible? By looking at just how much particularists and generalists might have to give away to make their theoretical viewpoints compatible, I will argue that particularists (...) can accept many of the concerns that motivate generalism because generalism can never be about ‘all’ conspiracy theories without being either ahistorical or apolitical. In the end generalist critiques are best seen as useful guidelines or considerations for the appraising of particular conspiracy theories. (shrink)

Conspiracy theories and conspiracy theorists have been accused of a great many sins, but are the conspiracy theories conspiracy theorists believe epistemically problematic? Well, according to some recent work, yes, they are. Yet a number of other philosophers like Brian L. Keeley, Charles Pigden, Kurtis Hagen, Lee Basham, and the like have argued ‘No!’ I will argue that there are features of certain conspiracy theories which license suspicion of such theories. I will also argue that these features only license a (...) limited suspicion of these conspiracy theories, and thus we need to be careful about generalising from such suspicions to a view of the warrant of conspiracy theories more generally. To understand why, we need to get to the bottom of what exactly makes us suspicious of certain conspiracy theories, and how being suspicious of a conspiracy theory does not always tell us anything about how likely the theory in question is to be false.

Looking at the recent spate of claims about “fake news” which appear to be a new feature of political discourse, I argue that fake news presents an interesting problem in epistemology. Te phenomena of fake news trades upon tolerating a certain indiference towards truth, which is sometimes expressed insincerely by political actors. Tis indiference and insincerity, I argue, has been allowed to fourish due to the way in which we have set the terms of the “public” epistemology that maintains what (...) is considered “rational” public discourse. I argue one potential salve to the problem of fake news is to challenge this public epistemology by injecting a certain ethical consideration back into the discourse. (shrink)

This introduction to this special issue of Inquiry looks at recent work in the philosophy of conspiracy theory theory. Looking at two related worries expressed in the wider conspiracy theory theory (the academic study of conspiracy theories) – the Problem of Conspiracy Theories and the Problem of Conspiracy Theorists – this special issue argues that recent work in the philosophy of conspiracy theories is getting all the more closer to not just an epistemic understanding of what, if anything, is wrong (...) with belief in conspiracy theories, but also a framework for both investigating conspiracy theories and understanding how we should talk about the beliefs of conspiracy theorists. (shrink)

Looking at the early work in the philosophy of conspiracy theory theory, I put in context the papers in this special issue on new work on conspiracy theory theory (itself the product of the 1st International Conference on the Philosophy of Conspiracy Theory held in February 2022), showing how this new generation of work not only grew out of, but is itself a novel extension of the first generation of philosophical interest in these things called ‘conspiracy theories’.

In this paper I interrogate the notion of `debunking conspiracy theories’, arguing that the term `debunk’ carries with it pejorative implications, given that the verb `to debunk’ is commonly understood as `to show the wrongness of a thing or concept’. As such, the notion of `debunking conspiracy theories’ builds in the notion that such theories are not just wrong but ought to be shown as being wrong. I argue that we should avoid the term `debunk’ and focus on investigating conspiracy (...) theories. Looking at recent research work in epistemology on conspiracy theory, I argue that the best way to avoid talk of `debunking’ conspiracy theories is by working with a non-pejorative definition of `conspiracy theory’, and forming communities of inquiry which allow us to investigate the warrant of such theories without the prejudice associated with working with a pejorative definition. (shrink)

Judging the warrant of conspiracy theories can be difficult, and often we rely upon what the experts tell us when it comes to assessing whether particular conspiracy theories ought to be believed. However, whereas there are recognised experts in the sciences, I argue that only are is no such associated expertise when it comes to the things we call `conspiracy theories,' but that the conspiracy theorist has good reason to be suspicious of the role of expert endorsements when it comes (...) to conspiracy theories and their rivals. The kind of expertise, then, we might associate with conspiracy theories is largely improvised—in that it lacks institutional features—and, I argue, ideally the product of a community of inquiry.

This reply to an ongoing debate between conspiracy theory researchers from different disciplines exposes the conceptual confusions that underlie some of the disagreements in conspiracy theory research. Reconciling these conceptual confusions is important because conspiracy theories are a multidisciplinary topic and a profound understanding of them requires integrative insights from different fields. Specifically, we distinguish research focussing on conspiracy *theories* (and theorizing) from research of conspiracy *belief* (and mindset, theorists) and explain how particularism with regards to conspiracy theories does not (...) mean we cannot define a problematic subclass of conspiracy beliefs, while avoiding the problems of generalism. We hope this reply helps conspiracy theory researchers recognize the differences between studying conspiracy theories and conspiracy beliefs and appreciate the possibilities for fruitful, integrative, and interdisciplinary research.

An overview of the current epistemic literature concerning conspiracy theories, as well as indications for future research avenues on the topic.

I’m to push back on Hill’s (2022) criticism in four ways. First: we need some context for the debate that occurred in the pages of the Social Epistemology Review and Reply Collective that so concerns Hill. Second: getting precise with our terminology (and not working with stereotypes) is the only theoretically fruitful way to approach the problem of conspiracy theories. Third: I address Hill’s claim there is no evidence George W. Bush or Tony Blair accused their critics, during the build-up (...) the invasion of Iraq in 2003ACE, as being “conspiracy theorists.” Fourth (and finally): I will gently suggest that Hill has succumbed to a stereotypical view of work in Philosophy on conspiracy theories.

An analysis of the recent efforts to define what counts as a "conspiracy theory", in which I argue that the philosophical and non-pejorative definition best captures the phenomenon researchers of conspiracy theory wish to interrogate.

Phenomenal conservatives claim that seemings are sui generis mental states and can thus provide foundational non-doxastic justification for beliefs. Many of their critics deny this, claiming, instead, that seemings can be reductively analyzed in terms of other mental states—either beliefs, inclinations to believe, or beliefs about one’s evidence—that cannot provide foundational non-doxastic justification. In this paper, I argue that no tenable semantic reduction of ‘seems’ can be formulated in terms of the three reductive analyses that have been proposed by critics (...) of phenomenal conservatism. This is because Moore-paradoxical statements are generated when each of the reductive analyses is substituted for ‘seems’ in statements like ‘The stick is straight, but it does not seem to me that it’s straight.’ Since the latter statement is not Moore-paradoxical, the three proposed reductive analyses of ‘seems’ are unsuccessful. Absent a successful semantic reduction, however, there is no good reason to think a successful metaphysical reduction of seemings is forthcoming. Thus, there is an additional reason, unnoticed in the existing literature, to think that seemings are sui generis mental states. (shrink)

The aim of this paper is to provide a conceptual framework that will help in understanding and evaluating, along social and ethical lines, the issue of killing day-old male chicks and two alternative directions of responsible innovations to solve this issue. The following research questions are addressed: Why is the killing of day-old chicks morally problematic? Are the proposed alternatives morally sound? To what extent do the alternatives lead to responsible innovation? The conceptual framework demonstrates clearly that there is a (...) moral “lock-in”, and why the killing of day-old chicks is indeed an issue. Furthermore, it is shown that both alternative directions address some important objections with regard to the killing of day-old chicks, but that they also raise new dilemmas. It also becomes clear that the framework enables and secures anticipation, reflection, deliberation with and responsiveness to stakeholders, the four dimensions of responsible innovation, in a structured way.

In this concluding chapter Dentith presents a synthesis of the views on offer, arguing that the various philosophical, sociological and psychology theses defended in this section point towards a necessary reorientation of the literature, one which requires we purge public discourse of the pejorative aspects of the terms ‘conspiracy theory’ and ‘conspiracy theorist’ and, rather, engage with conspiracy theories as theories (like we do with theories in the Sciences and the Social Sciences) appraising them on their particular merits. Not just (...) that, but there is even room in our discourse to celebrate and promote conspiracy theorising (as we do theorising in other domains) given the need to be ever vigilant with respect to the existence of conspiracies in our polities. Sometimes, Dentith argues, that even requires that we treat some on-the-face-of-it ridiculous conspiracy theories seriously and ask how and who should investigate them. (shrink)

A reply to “Why ‘Healthy Conspiracy Theories’ Are (Oxy)morons” by Pascal Wagner-Egger, Gérald Bronner, Sylvain Delouvée, Sebastian Dieguez and Nicolas Gauvrit.

Two and a half thousand years ago Greek philosophers "looked up at the sky and formed a theory of everything." Though their solutions are little credited today, the questions remain fresh. Early Greek thinkers struggled to come to terms with and explain the totality of their surroundings, to identitify an original substance from which the universe was compounded, and to reconcile the presence of balance and proportion with the apparent disorder of the cosmos. M. R. Wright examines cosmological theories of (...) the "natural philosophers" from Thales, Anaximander and Anaximenes to Plato, the Stoics and the NeoPlatonists. The importance of Babylonian and Egyptian forerunners is also emphasized. Cosmology in Antiquity is a comprehensive introduction to the cosmological thought in ancient times. (shrink)

Talk of fake news is rife in contemporary politics, but what is fake news, and how, if anything, does it differ from news which is fake? I argue that in order to make sense of the phenomenon of fake news, it is necessary to first define it and then show what does and does not fall under the rubric of ‘fake news’. I then go on to argue that fake news is not a new problem. Rather, if there is problem (...) with fake news it is its centrality in contemporary public debate. (shrink)

Research on conspiracy theories has proliferated since 2016, in part due to the US election of President Trump, the COVID-19 pandemic, and increasingly threatening environmental conditions. In the rush to publication given these concerning social consequences, researchers have increasingly treated as definitive a 2016 paper by Michael Wood (Political Psychology, 37(5), 695–705, 2016) that concludes that the phrase “conspiracy theory” has no negative effect upon people’s willingness to endorse a claim. We revisit Wood’s findings and its (re)uptake in the recent (...) literature. Is the label “conspiracy theory” a pejorative? If so, does it sway or affect people’s belief in specific claims of conspiracy (i.e. particular conspiracy theories), or is the effect one that concerns claims of conspiracy more generally (i.e. all conspiracy theories)? Through an examination of the conceptual and methodological scope of Wood’s work and the results of our similar quasi-experimental design, we argue that it is premature to suggest the label “conspiracy theory” has no impact on the believability of a claim, or that it has no rhetorical power.

Objectives: Recent legislative changes within the United Kingdom have stimulated professional debate about access to patient data within research. However, there is currently little awareness of public views about such research. The authors sought to explore attitudes of the public, and their lay representatives, towards the use of primary care medical record data for research when patient consent was not being sought.Methods: 49 members of the public and four non-medical members of local community health councils in South Wales, UK gave (...) their views on the value and acceptability of three current research scenarios, each describing access to data without patient consent.Results: Among focus group participants, awareness of research in primary care was low, and the appropriateness of general practitioners as researchers was questioned. There was general support for research but also concerns expressed about data collection without consent. These included lack of respect and patient control over the process. Unauthorised access to data by external agencies was a common fear. Current data collection practices, including population based disease registers elicited much anxiety. The key informants were equally critical of the scenarios and generally less accepting.Conclusions: This exploratory study has highlighted a number of areas of public concern when medical records are accessed for research without patient consent. Public acceptability regarding the use of medical records in research cannot simply be assumed. Further work is required to determine how widespread such views are and to inform those advising on confidentiality issues. (shrink)

Theoretical and empirical research in bioethics frequently focuses on ethical dilemmas or problems. This paper draws on anthropological and phenomenological sources to develop an alternative framework for bioethical enquiry that allows examination of a broader range of how the moral is experienced in the everyday lives of individuals and groups. Our account of moral experience is subjective and hermeneutic. We define moral experience as “Encompassing a person's sense that values that he or she deem important are being realised or thwarted (...) in everyday life. This includes a person's interpretations of a lived encounter, or a set of lived encounters, that fall on spectrums of right-wrong, good-bad or just-unjust”. In our conceptualisation, moral experience is not limited to situations that are heavily freighted with ethically-troubling ramifications or are sources of debate and disagreement. Important aspects of moral experience are played out in mundane and everyday settings. Moral experience provides a research framework, the scope of which extends beyond the evaluation of ethical dilemmas, processes of moral justification and decision-making, and moral distress. This broad research focus is consistent with views expressed by commentators within and beyond bioethics who have called for deeper and more sustained attention in bioethics scholarship to a wider set of concerns, experiences and issues that better captures what is ethically at stake for individuals and communities. In this paper we present our conceptualisation of moral experience, articulate its epistemological and ontological foundations and discuss opportunities for empirical bioethics research using this framework.

In What particularism about conspiracy theories entails Dentith responds to their critics and examines the case for a refined and revised thesis of Particularism, the argument that we should appraise individual and particular conspiracy theories rather than appraise them in light of our views of the class of conspiracy theories generally. Recent work in the Philosophy of Conspiracy Theories has presented challenges to Particularism simpliciter (or Naive Particularism). Dentith argues that by facing these challenges Particularism presents an even stronger case (...) for rejecting a generalist conception of what belief in conspiracy theories entails. (shrink)

In exploring their shared belief in the experiential nature of mental constructs, The Empiricists illuminates the different methodologies of these great Enlightenment philosophers and introduces students to important metaphysical and epistemological issues including the theory of ideas, personal identity, and skepticism. It will be especially useful in courses devoted (...) to the history of modern philosophy. (shrink)

Plato's Timaeus contains a powerful and influential myth, of the construction of the universe by a divine craftsman. A god imposes reason on necessity, to bring order from a primeval 'receptacle' of disordered matter. There results the 'child' that is the cosmos - a copy of an eternally-existing perfect model. Here eight new essays from a distinguished international cast, explore aspects of this challenging work: the principles of the mythical narrative, how the world soul and human body are formed, implications (...) for illness - mental and physical, the importance of music and harmonious proportion. Later developments are also treated: Aristotle's theory of generation, the commentary of Proclus and elements of modern evolutionary theory. (shrink)

Recent solutions to the curve-fitting problem, described in Forster and Sober ([1995]), trade off the simplicity and fit of hypotheses by defining simplicity as the paucity of adjustable parameters. Scott De Vito ([1997]) charges that these solutions are 'conventional' because he thinks that the number of adjustable parameters may change when the hypotheses are described differently. This he believes is exactly what is illustrated in Goodman's new riddle of induction, otherwise known as the grue problem. However, the 'number of adjustable (...) parameters' is actually a loose way of referring to a quantity that is not language dependent. The quantity arises out of Akaike's theorem in a way that ensures its language invariance. (shrink)

There is an ancient and ambiguous philosophical doctrine that perception is passive. This can mean that the mind contributes nothing to the content of our sensory experience: its power of perception is a mere receptivity. In this sense the principle has often been questioned, and is indeed doubtful on empirical grounds, given one reasonable interpretation of what it would be for the mind to make such a contribution.

Basham and Dentith argue that the danger of condemning both conspiracy theorists and their conspiracy theories in a democracy has grave consequences. They argue that we should encourage research into public concerns about influential institutions, especially in cases where a conspiracy has been alleged. Rather than dismiss conspiracy theorising, we should, encourage the politically crucial, historically proven gift of watchfulness in the citizen, and its sometimes necessary, proper and correct expression, conspiracy theory.

In current dairy farming it is possible to run a profitable farm without having to adapt the system to the needs of dairy cows. In such systems the interests of the farmer and animals often diverge. Consequently, specific animal welfare problems occur. Foot disorders in dairy cattle are an illustrative example resulting from the specific methods of housing and management in current dairy farming. Foot disorders and the resulting lameness are considered the most important welfare problem in dairy farming. However, (...) these foot disorders not only typify welfare problems related to certain housing systems, but they also lead to the premature culling of cows. The assessment of the impact of foot disorders on the welfare of dairy cows raised the question of whether premature culling affects animal welfare since it affects the longevity of a cow. We argue that this aspect of longevity is morally relevant as an animal welfare issue. In this paper we aim to explore whether longevity is both (a) a morally relevant aspect in the discussion on killing animals and (b) a constitutive element of animal welfare. In other words, we aim to explore whether longevity is an independent moral argument in an animal welfare discussion. We claim that longevity is not merely important as an indicator of animal welfare, but is also a constitutive element of animal welfare. We argue that we need a more integrated approach to animal welfare and that an assessment that includes the aspect of time is necessary. This view involves a shift from views on animal welfare in terms of functioning or feeling well to a view on animal welfare that includes the aspect of natural living in which species-specific development is important. To show the impact of these points of view, we look at the practical implications for choices concerning the management of foot disorders in dairy cattle. (shrink)
