The notion of “the burden of proof” plays an important role in real-world argumentation contexts, in particular in law. It has also been given a central role in normative accounts of argumentation, and has been used to explain a range of classic argumentation fallacies. We argue that in law the goal is to make practical decisions whereas in critical discussion the goal is frequently simply to increase or decrease degree of belief in a proposition. In the latter case, it is (...) not necessarily important whether that degree of belief exceeds a particular threshold (e.g., ‘reasonable doubt’). We explore the consequences of this distinction for the role that the “burden of proof” has played in argumentation and in theories of fallacy. (shrink)

Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

The ?values of sport? is a concept that is often used to justify actions and policies by a range of agents and agencies from coaches and teachers to governing bodies and educational institutions. From a philosophical point of view, these values deserve to be analysed with great care to make sure we understand their nature and reach. The aim of this paper is to critically examine the values carried by the educational conception of sport that Pierre de Coubertin developed and (...) to see how they relate to certain values in the philosophy of Friedrich Nietzsche. To be able to understand in depth the moral construct of de Coubertin's system, it is essential to delve into the entire system he builds in order to develop athletic participants closer to his ideal of what a human should be. This in turn rests on his conception of Man, which is comprised of body, spirit and character. An understanding of his structure opens the way to a broader awareness of de Coubertin's educational system, of which sport was only part. We will then see that the values are a consequence of this pedagogical search for the ideal human. It is argued that this ideal of a human is similar to the one described by Nietzsche as the Übermensch . A philosophical case study is conducted, taking as its object the story of the first recipient of the Pierre de Coubertin medal, which rewards fair play among Olympic competitors. Judging the story through Nietzschean eyes allows for his thoughts to be put into practice. His lesser-known texts such as Homer and Competition on the emulation of creative powers shed light on today's sports. Concepts such as guilt, excellence, will to power and effectiveness help us compare these two authors and understand that competition is not necessarily about dominating others, but more about generating human excellence.

Entscheidungen der Therapiebegrenzung und in der Betreuung am Lebensende sind häufig komplex und von ethischen Problemen begleitet. Im Mittelpunkt der Untersuchung steht die entscheidende Frage, wie hilfreich existierende „Ethik-Richtlinien“, die eine ethische Orientierung bei solchen Entscheidungen geben sollen, in der klinischen Praxis tatsächlich sind. Die Frage, welchen Nutzen „Ethik-Richtlinien“ bei der Entscheidungsfindung haben oder haben können, wird hier exemplarisch an einem klinischen Fallbeispiel aus einer Ethik-Kooperationsstudie in der Intensivmedizin analysiert. Vergleichend werden hierzu „Ethik-Richtlinien“ aus Deutschland, der Schweiz und aus Großbritannien (...) herangezogen, die Gegenstand eines internationalen Projekts zur Analyse von Richtlinien waren. Die Möglichkeiten und Grenzen einer ethischen Orientierung an „Ethik-Richtlinien“ bei Entscheidungsproblemen der Therapiebegrenzung und in der Betreuung am Lebensende werden anhand der Fallstudie diskutiert und illustriert. Abschließend werden Schlussfolgerungen für die Entwicklung ethischer Richtlinien für die klinische Praxis formuliert. (shrink)

Psychopathy is a disorder characterized by severe and frequent moral violations in multiple domains of life. Numerous studies have shown psychopathy-related limbic brain abnormalities during moral processing; however, these studies only examined negatively valenced moral stimuli. Here, we aimed to replicate prior psychopathy research on negative moral judgments and to extend this work by examining psychopathy-related abnormalities in the processing of controversial moral stimuli and positive moral processing. Incarcerated adult males (N = 245) completed a functional magnetic resonance imaging protocol (...) on a mobile imaging system stationed at the prison. Psychopathy was assessed using the Hare Psychopathy Checklist–Revised (PCL-R). Participants were then shown words describing three types of moral stimuli: wrong (e.g., stealing), not wrong (e.g., charity), and controversial (e.g., euthanasia). Participants rated each stimulus as either wrong or not wrong. PCL-R total scores were correlated with not wrong behavioral responses to wrong moral stimuli, and were inversely related to hemodynamic activity in the anterior cingulate cortex in the contrast of wrong > not wrong. In the controversial > noncontroversial comparison, psychopathy was inversely associated with activity in the temporal parietal junction and dorsolateral prefrontal cortex. These results indicate that psychopathy-related abnormalities are observed during the processing of complex, negative, and positive moral stimuli. (shrink)

In a recent commentary, Kim and colleagues argued that minimal-risk research should be deregulated so that such studies do not require review by an institutional review board. They claim that regulation of minimal-risk studies provides no adequate counterbalancing good and instead leads to a costly human subjects oversight system. We argue that the counterbalancing good of regulating minimal-risk studies is that oversight exists to ensure that respect for persons and justice requirements are satisfied when they otherwise might not be.

This book moves toward building a new and more comprehensive theory of literature, philosophy, psychology, and art. The extremely popular work of Ken Wilber, unites the best of both western and eastern thought and affirms that the stages of consciousness, more refined than that of the reasoning mind, do exist.

Humans exhibit the remarkable ability to solve complex, multi-step problems despite their limited capacity for search. We review the standard theory of problem solving, which posits that heuristic guidance makes this possible, but we also note that most studies have emphasized the role of domain-specific heuristics, which are not available for unfamiliar tasks, over more general ones. We describe FPS, a flexible architecture for problem solving that supports a variety of different strategies and heuristics, and we report its use in (...) an experiment that studies the effectiveness of two domain-independent criteria. The results suggest that such heuristics can make problem solving far more tractable, and they are generally consistent with our claim that their use offsets the drawbacks of bounded rationality.

ABSTRACTWe used an immersive virtual environment to examine avoidance learning in spider-fearful participants. In 3 experiments, participants were asked to repeatedly lift one of 3 virtual boxes, under which either a toy car or a spider appeared and then approached the participant. Participants were not told that the probability of encountering a spider differed across boxes. When the difference was large, spider-fearfuls learned to avoid spiders by lifting the few-spiders-box more often and the many-spiders-box less often than non-fearful controls did. (...) However, they hardly managed to do so when the probability differences were small, and they did not escape from threat more quickly. In contrast to the observed performance differences, spider-fearfuls and non-fearfuls showed equal competence, that is comparable post-experimental knowledge about the probability to encounter spiders under the 3 boxes. The limitations and implications of the present study are discussed. (shrink)

The forms of words as they appear in text and speech are central to theories and models of lexical processing. Nonetheless, current methods for simulating their learning and representation fail to approach the scale and heterogeneity of real wordform lexicons. A connectionist architecture termed thesequence encoderis used to learn nearly 75,000 wordform representations through exposure to strings of stress‐marked phonemes or letters. First, the mechanisms and efficacy of the sequence encoder are demonstrated and shown to overcome problems with traditional slot‐based (...) codes. Then, two large‐scale simulations are reported that learned to represent lexicons of either phonological or orthographic wordforms. In doing so, the models learned the statistics of their lexicons as shown by better processing of well‐formed pseudowords as opposed to ill‐formed (scrambled) pseudowords, and by accounting for variance in well‐formedness ratings. It is discussed how the sequence encoder may be integrated into broader models of lexical processing. (shrink)

A complete collection of Frank Sibley's articles on philosophical aesthetics, this volume includes five, remarkable, hitherto unpublished papers written in Sibley's later years. It addresses many topics, among them the nature of aesthetic qualities versus non-aesthetic qualities, the relation of aesthetic description to aesthetic evaluation, the different levels of evaluation, and the objectivity of aesthetic judgement. The later papers constitute both a significant development of Sibley's individual approach to aesthetics, such as his discussion of the distinction between (...) attributive and predicative uses of adjectives and of the aesthetic significance of tastes and smells, a topic Sibley considered to be much neglected.

Geographies of Exclusion identifies forms of social and spatial exclusion and subsequently examines the fate of knowledge of space and society which has been produced by members of excluded groups. Evaluating writing on urban society by women and black writers, David Sibley asks why such work is neglected by the academic establishment, suggesting that both the practices which result in the exclusion of minorities and those which result in the exclusion of knowledge have important implications for theory and method (...) in human geography. Drawing on a range of ideas from social anthropology, feminist theory, sociology, human geography and psychoanalysis, this book presents a fresh approach to geographical theory, highlighting the tendency of powerful groups to "purify" space and to view minorites as defiled and polluting, and exploring the nature of "difference" and the production of knowledge.

Are people rational? This question was central to Greek thought and has been at the heart of psychology and philosophy for millennia. This book provides a radical and controversial reappraisal of conventional wisdom in the psychology of reasoning, proposing that the Western conception of the mind as a logical system is flawed at the very outset. It argues that cognition should be understood in terms of probability theory, the calculus of uncertain reasoning, rather than in terms of logic, the calculus (...) of certain reasoning. (shrink)

Philosophers and psychologists make many different, seemingly incompatible parsimony claims in support of competing models of cognition in nonhuman animals. This variety of parsimony claims is problematic. Firstly, it is difficult to justify each specific variety. This problem is especially salient for Morgan's Canon, perhaps the most important variety of parsimony claimed. Secondly, there is no systematic way of adjudicating between particular claims when they conflict. I argue for a view of parsimony in comparative psychology that solves these problems, based (...) on Sober's view that parsimony claims are claims that one model is more plausible given background theory.

BackgroundCurrent guidelines do not clearly outline when assent should be attained from paediatric research participants, nor do they detail the necessary elements of the assent process. This stems from the fact that the fundamental justification behind the concept of assent is misunderstood. In this paper, we critically assess three widespread ethical arguments used for assent: children’s rights, the best interests of the child, and respect for a child’s developing autonomy. We then outline a newly-developed two-fold justification for the assent process: (...) respect for the parent’s pedagogical role in teaching their child to become an autonomous being and respect for the child’s moral worth.DiscussionWe argue that the ethical grounding for the involvement of young children in medical decision-making does not stem from children’s rights, the principle of best interests, or respect for developing autonomy. An alternative strategy is to examine the original motivation to engage with the child. In paediatric settings there are two obligations on the researcher: an obligation to the parents who are responsible for determining when and under what circumstances the child develops his capacity for autonomy and reasoning, and an obligation to the child himself. There is an important distinction between respecting a decision and encouraging a decision. This paper illustrates that the process of assent is an important way in which respect for the child as an individual can be demonstrated, however, the value lies not in the child’s response but the fact that his views were solicited in the first place.SummaryThis paper demonstrates that the common justifications for the process of assent are incomplete. Assent should be understood as playing a pedagogical role for the child, helping to teach him how specific decisions are made and therefore helping him to become a better decision-maker. How the researcher engages with the child supports his obligation to the child’s parents, yet why the researcher engages with the child stems from the child’s moral worth. Treating a child as having moral worth need not mean doing what they say but it may mean listening, considering, engaging or involving them in the decision. (shrink)

A recent article from Archives of Disease in Childhood outlined problems with the act of gaining child assent for research participation. However the arguments used in the article are incomplete or misguided. Rather than being harmful, assent should be seen as an ethically-appropriate way in which we can engage with the child about his participation in research. While additional clarification of the concept of assent is needed, the child's family context can provide us with a valuable guide to the way (...) we involve him in the decision-making process.

Sibley, Kello, Plaut, and Elman (2008) proposed the sequence encoder as a model that learns fixed‐width distributed representations of variable‐length sequences. In doing so, the sequence encoder overcomes problems that have restricted models of word reading and recognition to processing only monosyllabic words. Bowers and Davis (2009) recently claimed that the sequence encoder does not actually overcome the relevant problems, and hence it is not a useful component of large‐scale word‐reading models. In this reply, it is noted that the (...) sequence encoder has facilitated the creation of large‐scale word‐reading models. The reasons for this success are explained and stand as counterarguments to claims made by Bowers and Davis. (shrink)

Part of understanding the meaning and power of algorithms means asking what new demands they might make of ethical frameworks, and how they might be held accountable to ethical standards. I develop a definition of networked information algorithms as assemblages of institutionally situated code, practices, and norms with the power to create, sustain, and signify relationships among people and data through minimally observable, semiautonomous action. Starting from Merrill’s prompt to see ethics as the study of “what we ought to do,” (...) I examine ethical dimensions of contemporary NIAs. Specifically, in an effort to sketch an empirically grounded, pragmatic ethics of algorithms, I trace an algorithmic assemblage’s power to convene constituents, suggest actions based on perceived similarity and probability, and govern the timing and timeframes of ethical action.

In The Quiet Hours, Mike Melman records a vanishing era of Minnesota's towns and cities through a series of seventy black-and-white photographs taken from 1985 to 2002. Working in the half-light of predawn hours, Melman brings a new perspective to familiar places, one shaped by his training as an architect and his particular affinity for old buildings. Through his artistic and historic images, Melman exposes the speed at which American cities change and presents a gritty yet contemplative portrait of (...) urban Minnesota. (shrink)

Google Trends reveals that at the time we were writing our article on ‘The Coming Crisis of Empirical Sociology’ in 2007 almost nobody was searching the internet for ‘Big Data’. It was only towards the very end of 2010 that the term began to register, just ahead of an explosion of interest from 2011 onwards. In this commentary we take the opportunity to reflect back on the claims we made in that original paper in light of more recent discussions about (...) the social scientific implications of the inundation of digital data. Did our paper, with its emphasis on the emergence of, what we termed, ‘social transactional data’ and ‘digital byproduct data’ prefigure contemporary debates that now form the basis and rationale for this excellent new journal? Or was the paper more concerned with broader methodological, theoretical and political debates that have somehow been lost in all of the loud babble that has come to surround Big Data. Using recent work on the BBC Great British Class Survey as an example this brief paper offers a reflexive and critical reflection on what has become – much to the surprise of its authors – one of the most cited papers in the discipline of sociology in the last decade.

Robert Sibley examines how Watson, Grant, and Taylor found in Hegel the theoretical tools needed to respond to Canada's uncertain existence.

It has been argued that dual process theories are not consistent with Oaksford and Chater’s probabilistic approach to human reasoning (Oaksford and Chater in Psychol Rev 101:608–631, 1994 , 2007 ; Oaksford et al. 2000 ), which has been characterised as a “single-level probabilistic treatment[s]” (Evans 2007 ). In this paper, it is argued that this characterisation conflates levels of computational explanation. The probabilistic approach is a computational level theory which is consistent with theories of general cognitive architecture that invoke (...) a WM system and an LTM system. That is, it is a single function dual process theory which is consistent with dual process theories like Evans’ ( 2007 ) that use probability logic (Adams 1998 ) as an account of analytic processes. This approach contrasts with dual process theories which propose an analytic system that respects standard binary truth functional logic (Heit and Rotello in J Exp Psychol Learn 36:805–812, 2010 ; Klauer et al. in J Exp Psychol Learn 36:298–323, 2010 ; Rips in Psychol Sci 12:29–134, 2001 , 2002 ; Stanovich in Behav Brain Sci 23:645–726, 2000 , 2011 ). The problems noted for this latter approach by both Evans Psychol Bull 128:978–996, ( 2002 , 2007 ) and Oaksford and Chater (Mind Lang 6:1–38, 1991 , 1998 , 2007 ) due to the defeasibility of everyday reasoning are rehearsed. Oaksford and Chater’s ( 2010 ) dual systems implementation of their probabilistic approach is then outlined and its implications discussed. In particular, the nature of cognitive decoupling operations are discussed and a Panglossian probabilistic position developed that can explain both modal and non-modal responses and correlations with IQ in reasoning tasks. It is concluded that a single function probabilistic approach is as compatible with the evidence supporting a dual systems theory. (shrink)

Moral character is explored in all its dimensions: virtues, vices, attitudes, emotions, commitments, and personal relationships, in addition to right and wrong conduct. The aim is to stimulate personal reflection and group dialogue, rather than to offer solutions. It seeks to sharpen ideas which we use as tools in coping responsibly with our daily lives.
