We determine precisely those locally finite varieties of unary algebras of finite type which, when augmented by a ternary discriminator, generate a variety with a decidable theory.

ABSTRACT The gospel of Matthew is one of the most beloved and studied gospels in Christianity, having a rich history of reception. The purpose of this paper is to article study its reading in Brazil from selected intertitles in two biblical versions. The research aims to identify how the gospel has been received by Brazilian editors and readers and how editorial intertitles can provide evidence of such reception. In order to achieve such objective, the history of reading and the (...) history of the book are used as references, based on theories by Roger Chartier (2001, 2002, 2022), Robert Darnton (2010), Lucien Febvre and Henri-Jean Martin (2017), Gerard Genette (1997) and D.F. McKenzie (2018). (shrink)

Dominique Lestel is a French philosopher whose work is significant for the rethinking of animality and human-animal relations. Throughout such important books as _L’Animalité _, _Les Origines animales de la culture _ and _L’Animal singulier_, he offers a fierce critique of reductive, mechanistic models of animal behaviour, as well as a positive contribution to etho-ethnographic and phenomenological methods for understanding animal life. Centred around hybrid human–animal communities of shared interests, affects and meaning, his critical and speculative approach to the animal (...) sciences offers a vision of animals as acting subjects and bearers of culture, who form their own worlds and transform them in concert with human and other partners. In tracing the ways in which we share our lives with animals in the texture of animality, Lestel’s cutting-edge philosophical ethology also contributes to an overarching philosophical anthropology of the human as the most animal of animals. This book was originally published as a special issue of _Angelaki: Journal of the Theoretical Humanities. _. (shrink)

Technical results about the time dependence of eigenvectors of reduced density operators are considered, and the relevance of these results is discussed for modal interpretations of quantum mechanics which take the corresponding eigenprojections to represent definite properties. Continuous eigenvectors can be found if degeneracies are avoided. We show that, in finite dimensions, the space of degenerate operators has co-dimension 3 in the space of all reduced operators, suggesting that continuous eigenvectors almost surely exist. In any dimension, even when degeneracies are (...) hit, we find conditions under which a theorem due to Rellich can provide continuous eigenvectors. We use this result to formulate an extended version of the modal interpretation. We also discuss eigenvector instability which we argue poses a serious problem for the modal interpretation, even in our extended version. Many examples are given to illustrate the mathematics.

Evolutionary game theoretic accounts of justice attempt to explain our willingness to follow certain principles of justice by appealing to robustness properties possessed by those principles. Skyrms (1996) offers one sketch of how such an account might go for divide-the-dollar, the simplest version of the Nash bargaining game, using the replicator dynamics of Taylor and Jonker (1978). In a recent article, D'Arms et al. (1998) criticize his account and describe a model which, they allege, undermines his theory. I sketch a (...) theory of evolutionary explanations of justice which avoids their methodological criticisms, and develop a spatial model of divide-the-dollar with more robust convergence properties than the models of Skyrms (1996) and D'Arms et al. (1998). (shrink)

Recent discussions in critical social epistemology have raised the idea that the concept 'knower' is not only an epistemological concept, but an ethical concept as well. Though this idea plays a central role in these discussions, the theoretical underpinnings of the claim have not received extended scrutiny. This paper explores the idea that 'knower' is an irreducibly ethical concept in an effort to defend its use as a critical concept. In Section 1, I begin with the claim that 'knower' is (...) an irreducibly normative and social concept, drawing from some ideas in Wilfrid Sellars. In Section 2, I argue that one's being a knower involves demands for various sorts of ethically-laden recognition. I develop this thought by arguing that Axel Honneth's threefold typology of recognition—love, respect, and esteem—finds clear expression within the context of socio-epistemic practice. I conclude in Section 3 by arguing that Miranda Fricker's proposed " analogy " between epistemic and moral perception should be modified to indicate a closer relationship than mere analogy. (shrink)

Daniel Dennett is one of the most influential thinkers at the interface between philosophy and science. This book is the first comprehensive examination of Dennett ’s ideas on the nature of thought, consciousness, free will, and the significance of Darwinism. A highly original introduction to contemporary thinking about the relationship between mind and science. This is the first comprehensive examination of Dennett ’s ideas on the nature of thought, consciousness, free will, and the significance of Darwinism. Examines Dennett ’s unique (...) response to the question of when and how science should affect the conception that we have of ourselves. Casts new light on specific controversies: Could robots ever think, feel, and enjoy freedom? Does Dennett really explain consciousness? Are mental states real or merely ‘useful fictions’? Do we have free will? Is the self a ‘centre of narrative gravity’? (shrink)

The correspondence theory of truth is often thought to be supported by the intuition that if a proposition (sentence, belief) is true, then something makes it true. I argue that this appearance is illusory and is sustained only by a conflation of two distinct notions of truthmaking, existential and non-existential. Once the conflation is exposed, I maintain, deflationism is seen to be adequate for accommodating truthmaking intuitions.

This is a review of Eklund's book. It discusses his suggestion that "ardent realists" use the practical profiles of normative concepts to A) explain what it is for a concept to be normative, B) fix reference, and C) provide an extensional theory of normative properties. I argue that those sympathetic to ardent realism will be happier to focus on the way in which normativity presents itself to cognition, particularly that presentation of inherent, authoritative guidance, and whether that 1) explains what (...) it is for a concept to be normative, 2) fixes reference, 3) aptly characterizes the nature of normativity in the world, and perhaps 4) explains why normative thoughts have the Eklund-style normative roles—the practical profiles of things like motivation, preference, and intention—that they have.

Brings together and interprets previously hard-to-find texts, new translations and passages detailing the interplay between philosophy and psychopathology.

This paper develops a phenomenological account of what it is to lose a primitive and pervasive sense of certainty. I begin by considering Wolfgang Blankenburg’s descriptions of losing common sense or natural self-evidence. Although Blankenburg focuses primarily on schizophrenia, I note that a wider range of phenomenological disturbances can be understood in similar terms—one loses something that previously operated as a pre-reflective, unquestioned basis for experience, thought, and practice. I refer to this as the loss of certainty. Drawing upon and (...) integrating themes in the work of Wittgenstein and Husserl, I propose that losses of certainty centrally involve the inability to tolerate a certain kind of uncertainty. The contrast between having and lacking certainty is to be construed in terms of differing patterns or styles of nonlocalized, practical, bodily anticipation. I conclude by showing how this conception enables us to better understand various different disturbances to which human experience is susceptible. (shrink)

Accidents involving large trucks result in significant economic and social costs. As technological solutions have improved, behavioral factors contributing to accidents have risen in importance. The purpose of this research is to investigate how norms, consequences, and personal attitudes influence safety-related ethical judgments and behavioral intentions. The Hunt–Vitell’s theory of ethical decision-making is adapted to test how these factors influence truck drivers’ decisions containing ethical content. Professional truck drivers evaluated decisions presented in two scenarios that included the situation, the decision, (...) and the results. The research found that drivers rely heavily on evaluations of safety norms when forming ethical judgments and behavioral intentions. Further, drivers’ attitudes toward compliance and the effectiveness of safety regulations also influenced decision-making to an extent. Overall, evidence of a refutation of the assumption that a tradeoff exists between operational productivity and safety was discovered. Drivers in this study intended to behave in a certain manner irrespective of time or money pressures. The perceived ethical component of the decision outweighed regulatory and economic consequences under a range of parameters. (shrink)

The Bayesian Approach and the Classical Approach are two very different families of approaches to statistical inference. There are many different versions of each view, often with very substantial differences among them. But I will here endeavor to explain the philosophical core of each family of approaches, as well as to identify four main philosophical differences between them.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.1 (2004) 35-41 [Access article in PDF] The Rationality of Psychosis and Understanding the Deluded Matthew R. Broome Campbell's important and influential paper (Campbell 2001) has framed the debate that Bayne and Pacherie (2004) most explicitly, and Klee (2004) and Georgaca (2004) more implicitly, engage in. Campbell has offered two broad ways of thinking about explanations of delusions—the empirical and the rational. He offers (...) some criticism of the former and an endorsement of the latter. Campbell uses examples from clinical psychopathology to illustrate his argument and Bayne and Pacherie in turn employ these. Campbell discusses the eponymously named delusions of Capgras and Cotard—the former a subtype of delusional misidentification and the latter a delusion whose content is colored predominantly with nihilistic and possibly hypochondriacal themes. Campbell, Bayne and Pacherie, and Klee discuss the empirical data in relation to such delusions and as an aid to discussing the empirical model more generally. It does seem a little unfortunate that these delusions, which are less than typical, become the focus of Campbell's paper, and Bayne and Pacherie's criticism of his work. Delusions are remarkably heterogeneous; this indeed may be part of the reason why there is so much difficulty in reaching a definition as Klee discusses, and occur in a wide variety of mental and neurological illnesses. The most common delusions are those of persecution and reference (World Health Organization [WHO] 1973) and typically occur in schizophrenia. By contrast, delusional misidentification occurs most commonly in patients with dementia, delirium, and focal cognitive impairment, but can occur in other functional psychoses such as an affective or schizophrenic psychosis. The most common form of delusional misidentification is not that of either the exotic Capgras or Fregoli syndromes but delusional misidentification for place; thus, although Bayne and Pacherie's arguments against Campbell may still hold, delusional misidentification tends to occur in the context of a patient believing that they are at home or on holiday rather than in hospital and may not necessarily involve close family members or other intimate relationships. Similarly, Cotard's syndrome tends to occur in the context of a severe depressive illness with mood-congruent psychotic symptoms, typically in an elderly individual. It does not have to have the content that the deluded is dead, but can include beliefs, for example, that the world no longer exists or that their internal organs are not present. Thus, a patient with either Capgras' or Cotard's syndrome is likely to differ from patients with delusions of persecution. They would [End Page 35] have different diagnoses, probably be older, and have a greater likelihood of structural abnormalities of the brain on imaging and consequent neuropsychological dysfunction. That is not to say that patients with schizophrenia have normal cerebral anatomy and neuropsychology, but rather that the Capgras' and Cotard's patients are likely to have neurological quality to their presentation that is clinically relevant, rather than what commonly the case in schizophrenia and the other functional psychoses, where the neurological abnormalities are only currently important at the level of academic research. Empirical Models of Delusion Formation Different delusions may not have that much in common, nor may the patients who believe in them. This in turn relates to the empirical paradigm that both Campbell and Bayne and Pacherie discuss. It is true that current research, and indeed the clinical practice of cognitive behavioral therapy for psychosis, is indebted to the work of Maher and it is within his legacy which we work. This, however, is not to say that we think his initial formulation was correct. Maher's (1988, 1992) work focused attempts in explaining delusions—both to support and refute his thesis that delusions are the consequence of normal cognitive mechanisms seeking to explain an anomalous sensory experience. Such a view initially led to work demonstrating delusions in the absence of anomalous perceptions, the presence of reasoning biases in the deluded population, and the possibility that abnormal sensory experience may be consequent upon biased cognitive processes (Garety and Freeman 1999). More recent work has demonstrated the prevalence of... (shrink)

In this article, we highlight the importance of psychoanalysis and the Heideggerian concept of 'place' for each respective domain of inquiry. In particular, the writings of Jung and Lacan can unconceal and reveal new dimensions of Jeff Malpas's work on place. Alternatively, Malpas can extend the work of these psychoanalysts by showing new dimensions of their ideas through an analysis of 'place'. Ultimately, this article sets up a number of possibilities for future research through this novel interaction and engagement between (...) the philosophy of place and psychoanalysis. One of these possibilities is in genomics and genetic determinism, which we briefly acknowledge throughout. (shrink)

Television medical dramas frequently depict the practice of medicine and bioethical issues in a strikingly realistic but sometimes inaccurate fashion. Because these shows depict medicine so vividly and are so relevant to the career interests of medical and nursing students, they may affect these students' beliefs, attitudes, and perceptions regarding the practice of medicine and bioethical issues. We conducted a web-based survey of medical and nursing students to determine the medical drama viewing habits and impressions of bioethical issues depicted in (...) them. More than 80% of medical and nursing students watch television medical dramas. Students with more clinical experience tended to have impressions that were more negative than those of students without clinical experience. Furthermore, viewing of television medical dramas is a social event and many students discuss the bioethical issues they observe with friends and family. Television medical dramas may stimulate students to think about and discuss bioethical issues. (shrink)

In this article, we report a study in which 109 research-active mathematicians were asked to judge the validity of a purported proof in undergraduate calculus. Significant results from our study were as follows: (a) there was substantial disagreement among mathematicians regarding whether the argument was a valid proof, (b) applied mathematicians were more likely than pure mathematicians to judge the argument valid, (c) participants who judged the argument invalid were more confident in their judgments than those who judged it valid, (...) and (d) participants who judged the argument valid usually did not change their judgment when presented with a reason raised by other mathematicians for why the proof should be judged invalid. These findings suggest that, contrary to some claims in the literature, there is not a single standard of validity among contemporary mathematicians. (shrink)

This article looks at the strong links between Deleuze's molecular ontology and the fields of complexity and emergence, and argues that Deleuze's work implies a ‘philosophy of technology’ that is both open and dynamic. Following Simondon and von Uexküll, Deleuze suggests that technical objects are ontologically unstable, and are produced by processes of individuation and self-organization in complex relations with their environment. For Deleuze design is not imposed from without, but emerges from within matter. The fundamental departure for Deleuze, on (...) the basis of such an ontology, is to conceive of modes of relating to the evolution of technology. In this way Deleuze, along with Guattari, provides the basis for an ethics and a politics of becoming and emergent control that constitutes an alternative to the hubris of contemporary reductionist accounts of new areas such as nanotechnology.

This paper aims to take the measure of the strand of early modern anti-clericalism that was conveyed by the term “priestcraft”. Priestcraft amounted to the claim that priests had usurped civil power and accumulated material wealth by systematically deceiving the laity and its secular rulers. Religion as it was practised and avowed by believers in early modern Europe was left tainted by this charge since manifold aspects of religious practice and belief fell under the pall of the suspicion that they (...) were merely part of the ruse perpetrated through the centuries by greedy and power-hungry priests. While the English language was particularly effective in condensing this claim into the term in question, mistrust of the clergy informed numerous discourses unfolding in diverse confessional and intellectual contexts. The present article seeks to draw attention to the thematic richness of priestcraft as an object of historical inquiry by identifying the multiple ways in which this trope made its presence felt in the early modern world.

In this paper I give a definition of assertion that develops William P. Alston’s account. Alston’s account of assertion combines a responsibility condition R, which captures the appropriate socio-normative status that one undertakes in asserting something, with an explicit presentation condition, such that the speech act in some way presents the content of what is being asserted. I develop Alston’s account of explicit presentation and add a Brandomian responsibility condition. I then argue that this produces an attractive position on the (...) nature of assertion. (shrink)

When decisionally incapable patients need a surrogate to make medical decisions for them, sometimes the patient has not appointed a healthcare agent and there is intractable disagreement among potential surrogates of equal priority, legal rank, or relation to the patient (e.g., child vs. child, sibling vs. sibling). There is no ethical, legal, or professional consensus about how to identify the appropriate surrogate in such circumstances. This article presents a case study involving an elderly female patient whose four children disagree about (...) whether to continue life-sustaining treatment for their mother, along with an ethical analysis of various strategies for selecting the appropriate surrogate in cases of conflicting equal-rank family members. It critically examines three different strategies—chance, majority rules, and quality of relationship with the patient—and defends the third approach. (shrink)

We often knowingly teach false science. Such a practice conflicts with a prima facie pedagogical value placed on teaching only what’s true. I argue that only a partial dissolution of the conflict is possible: the proper aim of instruction in science is not to provide an armory of facts about what things the world contains, how they interact, and so on, but rather to contribute to an understanding of how science as a human endeavor works and what sorts of facts (...) about the world science aims to provide. Such an aim legislates for an increased prominence of history and philosophy in even secondary science education. (shrink)
