The purpose of this qualitative case study was to gain an in-depth understanding of how three award-winning secondary economics teachers demonstrated their pedagogical content knowledge (PCK), specifically horizon content knowledge, specialized content knowledge, knowledge of content and teaching, and knowledge of content and students. The teachers consistently connected economic content to other grades, subjects, and economic concepts and skills. Economic content was also regularly used to prepare students for citizenship, including casting more informed votes and understanding current events. However, authentic (...) discussions, including ones about controversial issues, were mostly lacking. An emphasis was placed on developing students’ economic reasoning skills, including real-world applications of the economic way of thinking and decision-making models. Additionally, active learning instructional practices were frequently incorporated, and economic content was almost always related to students’ interests and experiences. A detailed description of a first step toward a practice-based theory of PCK in secondary economics concludes the article. (shrink)

It’s commonly thought that, in conversation, speakers accept and reject propositions that have been asserted by others. Do speakers accept and reject questions as well? Intuitively, it seems that they do. But what does it mean to accept or reject a question? What is the relationship between these acts and those of asking and answering questions? Are there clear and distinct classes of reasons that speakers have for acceptance and rejection of questions? This chapter seeks to address these issues. Beyond (...) their intrinsic interest to those working on the nature of questions, solutions to these problems may aid the extension of inferentialist approaches to logic and language. Inferentialists who think that inferences should be conceived in terms of the norms we are subject to in virtue of both the sentences we accept or assert as well as those we reject or deny are known as bilateralists. A coherent account of accepting and rejecting questions raises the prospects for a bilateralism that interprets question-involving or erotetic inferences according to these additional primitives. While a full-blown bilateralism for erotetic inferences and ultimately for question-forming operators themselves far exceeds this chapter’s scope, the work presented here does sketch the first steps in that direction.

Background At the beginning of the coronavirus (Covid-19) pandemic, many non-Covid healthcare services were suspended. In April 2020, the Department of Health in England mandated that non-Covid services should resume, alongside the continuing pandemic response. This ‘resetting’ of healthcare services created a unique context in which it became critical to consider how ethical considerations did (and should) underpin decisions about integrating infection control measures into routine healthcare practices. We draw on data collected as part of the ‘NHS Reset Ethics’ project, (...) which explored the everyday ethical challenges of resetting England’s NHS maternity and paediatrics services during the pandemic. Methods Healthcare professionals and members of the public participated in interviews and focus group discussions. The qualitative methods are reported in detail elsewhere. The focus of this article is our use of Frith’s symbiotic empirical ethics methodology to work from our empirical findings towards the normative suggestion that clinical ethics should explicitly attend to the importance of relationships in clinical practice. This methodology uses a five-step approach to refine and develop ethical theory based on a naturalist account of ethics that sees practice and theory as symbiotically related. Results The Reset project data showed that changed working practices caused ethical challenges for healthcare professionals, and that infection prevention and control measures represented harmful barriers to the experience of receiving and offering care. For healthcare professionals, offering care as part of a relational interaction was an ethically important dimension of healthcare delivery. Conclusions Our findings suggest that foregrounding the importance of relationships across a hospital community will better promote the ethically important multi-directional expression of caring between healthcare professionals, patients, and their families. We offer two suggestions for making progress towards such a relational approach. First, that there is a change of emphasis in clinical ethics practice to explicitly acknowledge the importance of the relationships (including with their healthcare team) within which the patient is held. Second, that organisational decision-making should take into account the moral significance afforded to caring relationships by healthcare professionals, and the role such relationships can play in the negotiation of ethical challenges.

XML documents and, more generally, semistructured data, can be seen as labelled graphs. In this paper we set a correspondence between such graphs and the models of a language of hybrid multimodal logic. This allows us to characterize a schema for semistructured data as a formula of hybrid multimodal logic, and instances of the schema as models of this formula. We also investigate how to express in such a logic integrity constraints on semistructured data, in particular some classes of constraints (...) widely considered in the literature. The contribution of this work is twofold: 1) We generalize the notion of schema, by proposing a definition of schema were references are “well typed”. 2) We formalize semistructured data, schema for semistructured data and integrity constraints in a unique framework, namely hybrid multimodal logic.

This book argues for the use of nonideal theory in social ontology. The central claim is that a paradigm shift is underway in contemporary social ontology, from ideal to nonideal, and that this shift should be fully followed through. To develop and defend this central claim, the first step is to show that the key questions and central dividing lines within contemporary social ontology can be fruitfully reconstructed as a clash between two worlds, referred to as ideal and (...) nonideal social ontology. Ideal social ontology is characterized by consensus and cooperation, while nonideal social ontology is characterized by conflict and contestation. The second step is to show that, when taken together, objections to the standard model of ideal social ontology (the dominant version of ideal social ontology) imply that this model needs to be given up in favor of nonideal social ontology. In other words, we should look to nonideal rather than ideal social ontology for core concepts. The third step is to offer a positive account, called the power view, of nonideal social ontology. This account places the concept of social power at the core of a general theory of the social world and replaces the flat and narrow conception of power in ideal social ontology with a richer and more extensive conception. In addition, it rectifies a shortcoming in nonideal social ontology by attending to class, which has been notably and oddly overlooked in the literature. (shrink)

A class of metric theories of gravitation on Minkowski spacetime is considered, which is—provided that certain assumptions (staying close to the original ideas of Einstein) are made—the almost most general one that can be considered. In addition to the Minkowskian metric G a dynamical metric H (called the Einstein metric)is defined by means of a second-rank tensor field S (referred to as gravitational potential).The theory is defined by a Lagrangian ℒ, from which the field equations as well as, e.g., the (...) energy-momentum tensor field for the gravitational field follow. The case of weak fields is considered explicitly. The static, spherically and time-inversal symmetric field is calculated, and as a first step to investigate the theory's viability the parameters are fitted to the experimental data of the perihelion advance and the deflection of light at the Sun. Finally the question of gauge freedoms in the gravitational potential is briefly discussed. (shrink)

This paper discusses how to define logics as deductive limits of sequences of other logics. The case of da Costa's hierarchy of increasingly weaker paraconsistent calculi, known as $ \mathcal {C}$n, 1 $ \leq$ n $ \leq$ $ \omega$, is carefully studied. The calculus $ \mathcal {C}$$\scriptstyle \omega$, in particular, constitutes no more than a lower deductive bound to this hierarchy and differs considerably from its companions. A long standing problem in the literature (open for more than 35 years) is (...) to define the deductive limit to this hierarchy, that is, its greatest lower deductive bound. The calculus $ \mathcal {C}$min, stronger than $ \mathcal {C}$$\scriptstyle \omega$, is first presented as a step toward this limit. As an alternative to the bivaluation semantics of $ \mathcal {C}$min presented thereupon, possible-translations semantics are then introduced and suggested as the standard technique both to give this calculus a more reasonable semantics and to derive some interesting properties about it. Possible-translations semantics are then used to provide both a semantics and a decision procedure for $ \mathcal {C}$Lim, the real deductive limit of da Costa's hierarchy. Possible-translations semantics also make it possible to characterize a precise sense of duality: as an example, $ \mathcal {D}$min is proposed as the dual to $ \mathcal {C}$min. (shrink)

In a recent opinion paper, it was argued that individuals with multiple retractions or a record of academic misconduct should not serve as editors, including as editors-in-chief, on the editorial boards of scholarly or academic journals. As a first step towards appreciating how such a policy could be applied in practice, the presence of 30 individuals listed on the Retraction Watch Leaderboard on editorial boards was screened. Six cases are highlighted to gain an appreciation of the potential reputational (...) risks that journals and publishers might incur by including individuals with a tainted academic record on editorial boards. Given the reputational, legal and other risks associated with this type of assessment and decision, more formal positioning and guidance are needed by global ethics policy-related bodies such as COPE, the ICMJE, and the CSE, even more so in journals that claim to follow these organizations’ ethical guidelines.

In the past decade, the notion of a neural correlate of consciousness has become a focal point for scientific research on consciousness. A growing number of investigators believe that the first step toward a science of consciousness is to discover the neural correlates of consciousness. Indeed, Francis Crick has gone so far as to proclaim that ‘we need to discover the neural correlates of consciousness. For this task the primate visual system seems especially attractive. No longer need one (...) spend time attempting to endure the tedium of philosophers perpetually disagreeing with each other. Consciousness is now largely a scientific problem’. Yet the question of what it means to be a neural correlate of consciousness is actually far from straightforward, for it involves fundamental empirical, methodological, and philosophical issues about the nature of consciousness and its relationship to the brain. Even if one assumes, as we do, that states of consciousness causally depend on states of the brain, one can nevertheless wonder in what sense there is, or could be, such a thing as a neural correlate of consciousness.

Beginning in earnest in the late 1990s, educational researchers devoted increasing attention to the study of “active learning,” leading to a robust literature on the topic in the scholarship of teaching and learning. Meanwhile, during largely the same period, political theorists discovered the radical philosophy of Giorgio Agamben, which soon after began to ripple through more radical forms of philosophy of education. While both the SoTL works on active learning and writings of “Agambenian” philosophers of education have offered new insights (...) into their respective fields, active learning has not yet received a systematic philosophical reflection and the community of Agambenian philosophy of education has not yet been systematized. This article addresses both gaps, first through an outline of existing Agambenian approaches to the philosophy of education and second by theorizing active learning as a form of “destituent potential.” The systematic reflection on the three threads of Agambenian philosophy of education—whatever, potentiality, and study—offers an introduction to less familiar readers, and the second section offers a model for how philosophical concepts can become theoretical tools for SoTL analysis.

Classical logic has proved inadequate in various areas of computer science, artificial intelligence, mathematics, philosopy and linguistics. This is an introduction to extensions of first-order logic, based on the principle that many-sorted logic (MSL) provides a unifying framework in which to place, for example, second-order logic, type theory, modal and dynamic logics and MSL itself. The aim is two fold: only one theorem-prover is needed; proofs of the metaproperties of the different existing calculi can be avoided by borrowing them (...) from MSL. To make the book accessible to readers from different disciplines, whilst maintaining precision, the author has supplied detailed step-by-step proofs, avoiding difficult arguments, and continually motivating the material with examples. Consequently this can be used as a reference, for self-teaching or for first-year graduate courses. (shrink)

In Varia Socratica Professor A. E. Taylor devotes his first chapter to a proof that the impiety for which Socrates was condemned consisted in his connection with an Orphic-Pythagorean cult. This argument has more than historical interest, for it is the first step in an attempt to attribute to Socrates, and ultimately to Pythagorean sources, doctrines hitherto regarded as Platonic. Much of Dr. Taylor′s new evidence seems to rest on passages which in their context contradict or greatly (...) modify his inferences; other arguments have no better basis than the dubious principle that any fact shown to be related to Orphism in one connection is always so related; and, above all, the enquiry which set out to give precise legal grounds for the charge of impiety tails away lamentably into a mere discussion of doctrine. I propose, after examining the wording of the charge, to analyze the evidence for regarding Socrates′ offence as the importation of a foreign cultus, then to enquire how far Dr. Taylor′s discussion of doctrine is relevant to the legal charge, and, lastly, to ask whether the Apology of Plato and the Memorabilia really do preserve so suspicious a silence about the impiety as to justify a totally new theory to account for their reticence.

On the example of the online game Akinator, the basic principles on which programs of this type are built are considered. Effective technics have been proposed by which artificial intelligence systems can build logical inferences that allow to identify an unknown subject from its description. To confirm the considered hypotheses, the terminological analysis of definition of the program "Akinator" offered by the author is carried out. Starting from the assumptions given by the author's definition, the article complements their definitions presented (...) by other researchers and analyzes their constituent theses. Finally, some proposals are made for the next steps in improving the program. The Akinator program, at one time, became one of the most famous online games using artificial intelligence. And although this was not directly stated, it was clear to the experts in the field of artificial intelligence that the program uses the techniques of expert systems and is built on inference rules. At the moment, expert systems have lost their positions in comparison with the direction of neural networks in the field of artificial intelligence, however, in the case considered in the article, we are talking about techniques using both directions – hybrid systems. Games for filling semantics interact with the user, expanding their semantic base and use certain strategies to achieve the best result. The playful form of such semantics filling programs is beneficial for researchers by involving a large number of players. The article examines the techniques used by the Akinator program, and also suggests possible modifications to it in the future. This study, first of all, focuses on how the knowledge base of the Akinator program is built, it consists of incomplete sets, which can be filled and adjusted as a result of further iterations of the program launches. It is important to note our assumption that the order of questions used by the program during the game plays a key role, because it determines its strategy. It was identified that the program is guided by the principles of nonmonotonic logic – the assumptions constructed by the program are not final and can be rejected by it during the game. The three main approaches to acquisite semantics proposed by Jakub Šimko and Mária Bieliková are considered, namely, expert work, crowdsourcing and machine learning. Paying attention to machine learning, the Akinator program using machine learning to build an effective strategy in the game presents a class of hybrid systems that combine the principles of two main areas in artificial intelligence programs – expert systems and neural networks.

_Purpose__._ The authors aim to reveal the peculiarity of comprehension of the human phenomenon in the process of referring to the text of "Observations on the Feeling of the Beautiful and Sublime" by the early Immanuel Kant, which is based on the critical rethinking of the Enlightenment position. A prerequisite for its substantial solution is addressing the problem of the place of the "Observations" in the evolution of Kant’s anthropological views. _Theoretical basis__._ Our view of Kant’s legacy is based upon (...) the conceptual positions of phenomenology, existentialism and hermeneutics. _Originality__._ We have proved that the anthropological interest was inherent in Kant already in the pre-critical stage of his work, as shown by the still underestimated treatise "Observation". The paper give arguments that this text highlights the main topics that will later be the subject of a detailed study of both Kant himself and philosophical anthropology of the 20th century. It is revealed that Kant overcomes the Enlightenment temptation to absolutize the power of human reason and emphasizes its limitations. The specified step is a necessary condition for him to comprehend the important role of the sensual-passionate component of human nature and to recognize the importance of the metaphysical nature of man. _Conclusions._ For us today, the pre-critical Kant appears as the developer of anthropological teaching, first presented in the treatise "Observations". Already at this stage, Kant demonstrates a holistic vision of human nature. In the process of creative evolution of the thinker, this treatise should be qualified as a kind of sketch of the future concentrated development of human nature, elaborated in the pages of "Anthropology" in 1798. The author gives a key place to the metaphysics of human nature, a vivid illustration of which is, in particular, the last paragraph of "Observations" dedicated to freedom. The conducted analysis provides sufficient grounds for qualifying this text as an outline of the anthropological basis of his doctrine of pure reason, the doctrine of metaphysics as the metaphysics of man, which, in turn, gives us the key to understanding "Anthropology" as his final text.

This essay some first steps toward the naturalization of what I call rational intentionality or alternatively type II intentionality. By rational or type II intentionality, I mean that full combination of rational powers and content-bearing states that is paradigmatically enjoyed by mature intact human beings. The problem I set myself is to determine the extent to which the only currently extant approach to the naturalization of the intentional that has the singular virtue of not being a non-starter can be (...) aggregated up into an account of rational intentionality. I have in mind a broadly defined family of accounts whose main members are the indicator/information-theoretic approach of Dretske (1988), the asymmetric dependence theory of Jerry Fodor (1987, 1990, 1994) and the teleo-semantics of Ruth Millikan (1984, 1993). Somewhat inaccurately, I will call this family of approaches the information-theoretic family. To be sure, there is only a rough family resemblance among the members of the information-theoretic family. Indeed, several intense quarrels divide the members of that family one from another, but the precise outcome of those internecine struggles is not directly relevant to the aims of this essay. ² Taken collectively, the information-theoretic family yields a compelling picture of the place of at least a crude form of intentionality -- what I call frog-like or type I intentionality -- in the natural order. Though frog-like or type I intentionality is, I think, a genuine species of intentionality, it may subsist in the absence of rational powers. It is that species of intentionality enjoyed by irritable creatures who, following Brandom (1994). (shrink)

Huston Smith has argued that the universal source of wholeness, which he refers to as the primordial tradition, is essential to a meaningful life. Indeed embracing this tradition is, said Smith, an act of rejoining the human race. Our current forms of organized religion offer us ritualized expressions of this tradition, yet often fail to provide us with transpersonal growth; it is this transpersonal growth that reconnects us with the source of religion. This essay differentiates mainstream religion from a way (...) that we can begin to construct a physical theory of the primordial tradition–a necessary first step toward reclaiming the source of religion.

Based on a theoretical exploration in a previous article, this paper empirically analyzes which issues of SD are taken into account by corporations and stakeholders in what way, and to what extent the concept of sustainable development (SD) can be achieved through stakeholder relations management (SRM) on the corporate level. An important basis for this empirical analysis is a referential framework, which specifies 14 issues of SD. In a first empirical step, the literature-based framework has been operationalized for (...) the business world by analyzing sustainability reports. In a second empirical step, the operationalized framework served as the basis for a survey of selected MNCs. The analyses of the sustainability reports and the survey show how MNCs deal with particular issues of SD and what role they perceive particular stakeholders play. A key conclusion of the article is that SRM indeed promotes SD, but that it is no alternative to predictable government regulation. (shrink)

Physical superpositions exist both in classical and in quantum physics. However, what is exactly meant by ‘superposition’ in each case is extremely different. In this paper we discuss some of the multiple interpretations which exist in the literature regarding superpositions in quantum mechanics. We argue that all these interpretations have something in common: they all attempt to avoid ‘contradiction’. We argue in this paper, in favor of the importance of developing a new interpretation of superpositions which takes into account contradiction, (...) as a key element of the formal structure of the theory, “right from the start”. In order to show the feasibility of our interpretational project we present an outline of a paraconsistent approach to quantum superpositions which attempts to account for the contradictory properties present in general within quantum superpositions. This approach must not be understood as a closed formal and conceptual scheme but rather as a first step towards a different type of understanding regarding quantum superpositions. (shrink)

Learning a novel environment involves integrating first-person perceptual and motoric experiences with developing knowledge about the overall structure of the surroundings. The present experiments provide insights into the parallel development of these egocentric and allocentric memories by intentionally conflicting body- and world-centered frames of reference during learning, and measuring outcomes via online and offline measures. Results of two experiments demonstrate faster learning and increased memory flexibility following route perspective reading (Experiment 1) and virtual navigation (Experiment 2) when participants begin (...) exploring the environment on a northward (vs. any other direction) allocentric heading. We suggest that learning advantages due to aligning body-centered (left/right/forward/back) with world-centered (NSEW) reference frames are indicative of three features of spatial memory development and representation. First, memories for egocentric and allocentric information develop in parallel during novel environment learning. Second, cognitive maps have a preferred orientation relative to world-centered coordinates. Finally, this preferred orientation corresponds to traditional orientation of physical maps (i.e., north is upward), suggesting strong associations between daily perceptual and motor experiences and the manner in which we preferentially represent spatial knowledge.

What is the origin of individual differences in ideology and personality? According to the parasite stress hypothesis, the structure of a society and the values of individuals within it are both influenced by the prevalence of infectious disease within the society's geographical region. High levels of infection threat are associated with more ethnocentric and collectivist social structures and greater adherence to social norms, as well as with socially conservative political ideology and less open but more conscientious personalities. Here we use (...) an agent-based model to explore a specific opportunities-parasites trade-off hypothesis, according to which utility-maximizing agents place themselves at an optimal point on a trade-off between the gains that may be achieved through accessing the resources of geographically or socially distant out-group members through openness to out-group interaction, and the losses arising due to consequently increased risks of exotic infection to which immunity has not been developed. We examine the evolution of cooperation and the formation of social groups within social networks, and we show that the groups that spontaneously form exhibit greater local rather than global cooperative networks when levels of infection are high. It is suggested that the OPTO model offers a first step toward understanding the specific mechanisms through which environmental conditions may influence cognition, ideology, personality, and social organization.

This is the first part of a two-volume study which may very well represent a turning point of scholarship on Heidegger and a step beyond his position. Paradoxically this work is outstanding both as criticism and as close interpretation of Heidegger. The critical perspectives on Heidegger developed by Regina carry to their natural conclusion some important analyses of the theme of finitude contributed by his colleague, E. Severino, in the mid-sixties. These analyses made clearer the relationship between finitude (...) and the nihilistic tendencies discovered by Heidegger in Western thought. What Heidegger calls metaphysics is the history of the efforts to negate finitude and contingency by ascribing necessity and original worth to one or another ontic property of beings. Heidegger promised on various occasions a destructive history of metaphysics, but his thought in this respect has developed in fragments--on Nietzsche, Descartes, Leibniz, Kant, Plato, Aristotle, and the Presocratics--which require a considerable work of piecing together. Regina's own thesis on finitude, which parallels the important contributions of Michel Henry, makes these pieces fit in what is possibly the best ensemble yet devised with them. A truly brilliant feature of this interpretation is its emphasis on the role attributed to Kant by Heidegger, a role which places Kant outside Western metaphysics and among the pioneers of theoretical investigation of the ties between finitude and transcendence. The direction in which this first part of Regina's work points is that of a possible refocusing on those aspects of Heidegger's work that revalue human dignity. Such refocusing can have so productive an impact on the unification of philosophical work in Europe that the second part of this study should be anxiously awaited.--A. M. (shrink)

In activist circles feminist political thought is often viewed as abstract because it does not help activists make the kinds of arguments that are generally effective with donors and policy makers. The feminist political philosopher's focus on how we know and what counts as knowledge is a large step away from the terrain in which activists make their arguments to donors. Yet, philosophical reflection on the relations between power and knowledge can make a significant contribution to women's human rights (...) work in the area of evaluation. Feminist political philosophy can offer guidelines for how to evaluate the work of women's human rights organizations and their funders in light of the social, political, and economic conditions that render their work necessary and difficult. This article offers 1) an account of the difficulty in showing the impact of social change activism using conventional modes of measurement, particularly those that focus on first order effects, 2) feminist theoretical insights into the interrelatedness of global gender injustices that may help us develop better benchmarks of evaluation for women's human rights programming, and 3) a sketch of how to approach the evaluation of organizations and donors who seek to support global gender justice.

Most moral theorists agree that it is one thing to believe that someone has slighted you and another to resent her for the insult; one thing to believe that someone did you a favor and another to feel gratitude toward her for her kindness. While all of these ways of responding to another's conduct are forms of moral appraisal, the reactive attitudes are said to 'go beyond' beliefs in some way. We think this claim is adequately explained only when we (...) take seriously the fact that reactive attitudes are emotions. In this paper, we appeal to insights of the emotions literature to highlight one key way in which reactive attitudes go beyond beliefs: beliefs about a person and her morally significant conduct merely ascribe to the person the property of having performed a morally significant action, while reactive attitudes are ways of experiencing that person as having performed a morally significant action. We then suggest that appreciating this is a crucial first step toward understanding why reactive emotions play roles in our practices around responsibility that beliefs do not. (shrink)

In this paper I will argue that Boghossian's explanation of how we can acquire a priori knowledge of logical principles through implicit definitions commits a transmission of warrant-failure. To this end, I will briefly outline Boghossian's account, followed by an explanation of what a transmission of warrant-failure consists in. I will also show that this charge is independent of the worry of rule-circularity which has been raised concerning the justification of logical principles and of which Boghossian is fully aware. My (...) argument comes in two steps: firstly, I will argue for the insufficiency of Boghossian's template which is meant to explain how a subject can acquire a warrant for logical principles. I will show however that this insufficiency of his template can be remedied by adopting what I call the Disquotational Step. Secondly, I will argue that incorporating this further step makes his template subject to a transmission of warrant-failure, assuming that certain rather basic and individually motivated principles hold. Thus, Boghossian's account faces a dilemma: either he adopts the Disquotational Step and subjects his account to the charge of a transmission of warrant-failure, or he drops this additional step leaving the account confronted with explaining the gap that has previously been highlighted. I will then suggest various rejoinders that Boghossian might adopt but none of which - I will argue - can resolve the dilemma. Lastly, I will raise and briefly discuss the question whether this worry generalizes to other accounts, such as Hale and Wright's that aim to explain our knowledge of logic and/or mathematics in virtue of implicit definitions.

Step therapy is an insurance company policy whereby patients must try a less costly treatment and fail-first before the insurer will cover another, more costly treatment. This article argues that there are relevant and well-established principles of medical ethics—the duty to practice evidenced-based medicine and the duty to consider cost-effectiveness when treating patients—that constrain and guide physician behavior with respect to step therapy; clinical practice guidelines promulgated by authoritative physician groups attempt to incorporate and reconcile the competing (...) demands of evidenced-based and cost-effective medicine, although it is unclear whether they do so in a manner that appropriately considers all relevant ethical factors relating to cost-effectiveness; and despite the potential shortcomings of CPGs, the ethical principles guiding and constraining physician behavior can help demarcate the ethical boundaries for other actors in the drug prescribing and reimbursement matrix, including insurance companies and benefit managers.

This paper begins the development of a pragmatics of emotion based on the pragma-dialectical programme, Externalization, Socialization, Functionalization, and Dialectification, applied to the emotional mode of argumentation. The first step points out a systematic equivocation within pragma-dialectics between the notion of argument and that of 'dialectics.' With this cleared, it is shown that each of the first three main assumptions can be altered to accommodate a non-logical mode of communication. However, dialectification, insofar as it is actually defining (...) of the dialectical mode, must be created anew. A defining assumption for emotionality is presented as a replacement for dialectification. (shrink)

Traditionally, many writers, following Kleene (1952), thought of the Church-Turing thesis as unprovable by its nature but having various strong arguments in its favor, including Turing’s analysis of human computation. More recently, the beauty, power, and obvious fundamental importance of this analysis, what Turing (1936) calls “argument I,” has led some writers to give an almost exclusive emphasis on this argument as the unique justification for the Church-Turing thesis. In this chapter I advocate an alternative justification, essentially presupposed by Turing (...) himself in what he calls “argument II.” The idea is that computation is a special form of mathematical deduction. Assuming the steps of the deduction can be stated in a first order language, the Church-Turing thesis follows as a special case of Gödel’s completeness theorem (first order algorithm theorem). I propose this idea as an alternative foundation for the Church-Turing thesis, both for human and machine computation. Clearly the relevant assumptions are justified for computations presently known. Other issues, such as the significance of Gödel’s 1931 Theorem IX for the Entscheidungsproblem, are discussed along the way. (shrink)

Page argues convincingly for several important properties of localist representations in connectionist models of cognition.

With Artificial Intelligence entering our lives in novel ways—both known and unknown to us—there is both the enhancement of existing ethical issues associated with AI as well as the rise of new ethical issues. There is much focus on opening up the ‘black box’ of modern machine-learning algorithms to understand the reasoning behind their decisions—especially morally salient decisions. However, some applications of AI which are no doubt beneficial to society rely upon these black boxes. Rather than requiring algorithms to be (...) transparent we should focus on constraining AI and those machines powered by AI within microenvironments—both physical and virtual—which allow these machines to realize their function whilst preventing harm to humans. In the field of robotics this is called ‘envelopment’. However, to put an ‘envelope’ around AI-powered machines we need to know some basic things about them which we are often in the dark about. The properties we need to know are the: training data, inputs, functions, outputs, and boundaries. This knowledge is a necessary first step towards the envelopment of AI-powered machines. It is only with this knowledge that we can responsibly regulate, use, and live in a world populated by these machines. (shrink)

This essay focuses on the concept of consciousness in C. S. Peirce’s work, revealing how its ways of being are associated with the three Peircean phenomenological categories. In this article, I intend to reflect on the heuristic power of the mind, namely, its ability to bring about new ideas, which, within Peirce’s logic of inquiry, is called by the well-known term of abduction. The abductive logical step promotes a synthesis of signs that constitutes a logical structure capable of proposing (...) a new mediation or representation of a new phenomenon. I make use of a metaphorical passage from Peirce not only to give the title to this essay, but also to highlight the importance of the first category as a sort of synechistic envelopment of an unprecedented logical structure of signs that composes a new synthesis. Two continua intertwine themselves, namely, those of the first and third categories, to account for what appears as a fact of the world in the theater of secondness. The essay also seeks to bring to light the core realism of Peirce’s philosophy, the genetic aspect of this bottomless lake, through its cosmology, where the generalization of forms and the acquisition of habits of reality are the proper ground of his Objective Idealism. One of the heuristic aspect of the lake metaphor is a sort of invitation to extend the concept of synthesis from the realm of logical structures to that one of arts, which in this essay will remain as a suggestion for a further reflection.

In The Netherlands, neonatal euthanasia has become a legal option and the Groningen Protocol contains an approach to identify situations in which neonatal euthanasia might be appropriate. In the 5 years following the publication of the protocol, neither the prediction that this would be the first step on a slippery slope, nor the prediction of complete transparency and legal control became true. Instead, we experienced a transformation of the healthcare system after antenatal screening policy became a part of (...) antenatal care. This resulted in increased terminations of pregnancy and less euthanasia. (shrink)

Consciousness is widely perceived as a phenomenon that poses a special explanatory problem for science. The problem arises from the apparent rift between immediate first-person acquaintance with consciousness and our inability to provide an objective/scientific third-person characterization of consciousness. In this paper, I outline a theory of perceptual consciousness called the 'Quantum Uncertainty Reduction (QUR)1 Theory of Access and Phenomenal Consciousness'. The theory offers a functional solution to the hard problem of consciousness in terms of quantum information processing in (...) a Bayesian brain-inspired information processing system. I argue that the central aspect/step of information processing, namely, quantum uncertainty reduction, gives rise to qualitative properties of phenomenal and access consciousness. (shrink)

We suggest that the emerging field of the conservation humanities can play a valuable role in biodiversity protection in Papua New Guinea (PNG), where most land remains under collective customary clan ownership. As a first step to mobilising this scholarly field in PNG and to support capacity development for PNG humanities academics, we conducted a landscape review of PNG humanities teaching and research relating to biodiversity conservation and customary land rights. We conducted a systematic literature review, a PNG (...) teaching programme review, and a series of online workshops between the authors (10 PNG-based, 7 UK-based). We found a small but notable amount of PNG research and teaching focused on biodiversity conservation or customary land rights. This included explicit discussion of these topics in 8 of 156 PNG-authored humanities texts published 2010-2020 and related teaching content in the curricula of several different humanities-based programmes. We discuss current barriers to PNG academic development. The growth of fully fledged in-country conservation humanities will require a joint collaborative effort by PNG researchers, who are best placed to carry out such work, and researchers from abroad who can access resources to support the process.

Initially identified as a key phosphoinositide that controls membrane trafficking at the Golgi complex, phosphatidylinositol‐4‐phosphate (PI4P) has emerged as a key molecule in the regulation of a diverse array of cellular functions. In this review we will discuss selected examples of the findings that in the last few years have significantly increased our awareness of the regulation and roles of PI4P in the Golgi complex and beyond. We will also highlight the role of PI4P in infection and cancer. We believe (...) that, with the increasing number of regulators and effectors of PI4P identified, the time is ripe for a more integrated approach of study. A first step in this direction is the delineation of PI4P‐centered molecular networks that we provide using data from low and high throughput studies in yeast and mammals. (shrink)

Wittgenstein's conception of the general form of a truth function given in thesis 6 can be presented as a sort of a trade-off: the author of the Tractatus is unable to reconcile the simplicity of his original idea of a series of forms with the simplicity of his generalisation of Sheffer's stroke; therefore, he is forced to sacrifice one of them. As we argue in this paper, the choice he makes – to weaken the logical constraints put on the concept (...) of a series of forms, thus effectively metaphorising that concept for the sake of upholding the N-operation's role of generating the series – is unfortunate. An actual expansion of a series of truth functions as defined in 6 would require either making decisions at each step (Anscombe) or outwardly rejecting the concept of a series (Sundholm). However, neither is faithful to Wittgenstein's own fundamental intuitions regarding the nature of logic. For this reason, a different trade-off that prioritises upholding the basic features of a series of forms over the simplicity of the operation that generates that series seems to be much more reasonable. We offer such a trade-off by developing the schema already present in the Tractatus (5.101). The key element of our alternative solution is the construction of an operation that can perform the task of producing all consecutive truth functions of a given collection of atomic propositions as an invariant difference between any base and its successor throughout the series. We define it as a composition of three functions (in an algebraic sense): the first turns a symbol of a given truth function into a binary number, the second increments that number, the third turns the result back into a symbol of another truth function. We also show how the operation can be defined by means of a different notation without invoking binary arithmetic. (shrink)

Overdiagnosis refers to diagnosis that does not benefit patients because the diagnosed condition is not a harmful disease in those individuals. Overdiagnosis has been identified as a problem in cancer screening, diseases such as chronic kidney disease and diabetes, and a range of mental illnesses including depression and attention deficit hyperactivity disorder. In this paper, we describe overdiagnosis, investigate reasons why it occurs, and propose two different types. Misclassification overdiagnosis arises because the diagnostic threshold for the disease in question has (...) been set at a level where many people without harmful disease are nonetheless diagnosed. We illustrate misclassification overdiagnosis using the example of chronic kidney disease. Misclassification occurs in diseases diagnosed using biomarkers or based on patient reported phenomena. Maldetection overdiagnosis arises because, at the time the diagnosis is made and despite the presence of a 'gold standard' diagnostic test, it is not possible to discriminate between harmful and non-harmful cases of the index disease. We illustrate maldetection overdiagnosis using the example of thyroid cancer. While there is some overlap between misclassification and maldetection overdiagnosis, this conceptual analysis helps to clarify the phenomenon of overdiagnosis and is a necessary first step in developing strategies to address the problem.

What is the biological basis for human cognition? Our understanding why human brains make us smarter than other animals is still in its infancy. In recent years, astrocytes have been shown to be indispensable for neuronal survival, growth, synapse formation, and synapse function. Now, in a new study from Maiken Nedergaard and Steven Goldman's groups (Han et al., 2013), human glia progenitor cells have been transplanted into mouse forebrains. These progenitors survived, migrated widely, and gave rise to astrocytes that displayed (...) the characteristics of human astrocytes in the rodent host brains. Strikingly, the mice with transplanted human cells displayed improved long term potentiation (LTP) and learning, suggesting the potential importance of human astrocytes in the unique cognitive abilities of human brains. This landmark paper is an important first step toward future investigations of whether and how human astrocytes play a role in distinguishing the cognitive abilities of humans from those of other animals.

How, if at all, consciousness can be part of the physical universe remains a baffling problem. This article outlines a new, developing philosophical theory of how it could do so, and offers a preliminary mathematical formulation of a physical grounding for key aspects of the theory. Because the philosophical side has radical elements, so does the physical-theory side. The philosophical side is radical, first, in proposing that the productivity or dynamism in the universe that many believe to be responsible (...) for its systematic regularities is actually itself a physical constituent of the universe, along with more familiar entities. Indeed, it proposes that instances of dynamism can themselves take part in physical interactions with other entities, this interaction then being “meta-dynamism” (a type of meta-causation). Secondly, the theory is radical, and unique, in arguing that consciousness is necessarily partly constituted of meta-dynamic auto-sensitivity, in other words it must react via meta-dynamism to its own dynamism, and also in conjecturing that some specific form of this sensitivity is sufficient for and indeed constitutive of consciousness. The article proposes a way for physical laws to be modified to accommodate meta-dynamism, via the radical step of including elements that explicitly refer to dynamism itself. Additionally, laws become, explicitly, temporally non-local in referring directly to quantity values holding at times prior to a given instant of application of the law. The approach therefore implicitly brings in considerations about what information determines states. Because of the temporal non-locality, and also because of the deep connections between dynamism and time-flow, the approach also implicitly connects to the topic of entropy insofar as this is related to time.

This paper provides a new analysis of e - trust , trust occurring in digital contexts, among the artificial agents of a distributed artificial system. The analysis endorses a non-psychological approach and rests on a Kantian regulative ideal of a rational agent, able to choose the best option for itself, given a specific scenario and a goal to achieve. The paper first introduces e-trust describing its relevance for the contemporary society and then presents a new theoretical analysis of this (...) phenomenon. The analysis first focuses on an agent’s trustworthiness , this one is presented as the necessary requirement for e-trust to occur. Then, a new definition of e-trust as a second-order-property of first-order relations is presented. It is shown that the second-order-property of e-trust has the effect of minimising an agent’s effort and commitment in the achievement of a given goal. On this basis, a method is provided for the objective assessment of the levels of e-trust occurring among the artificial agents of a distributed artificial system. (shrink)

All of the selections in this volume have been newly translated and many of them appear for the first time in English. The editors group well-chosen selections from the Renaissance Italian philosophers around four areas of development of philosophy passing out of the middle ages and into modern philosophy. Renaissance Humanism is represented by Petrarch, Leon Alberti, Lorenzo Valla, and Gianozzo Manetti. Renaissance Platonism includes selections from Pico della Mirandola, Marsilio Ficino, and Leone Ebreo. Renaissance Aristotelianism has pieces from (...) Pomponazzi and Tasso. The Philosophers of Nature included are Telesio, Campanella, and Bruno. Courses in the History of Philosophy too often pass over the Renaissance philosophers, much in the same way as these same courses used to pass over the Middle Ages. Considering the effect that the revitalized Platonism of the Renaissance period had on Descartes and Leibniz, this gap needs to be filled in for a proper understanding of the origins of modern philosophy; this anthology, and, presumably, the companion volume to follow are welcome steps in that direction.—E.

Twenty years ago, Australian biomedical researchers took the first steps along a pathway toward common ground with opponents of the use of animals in science. Leaders of Australian medical research at that time saw the necessity of established science facing the ethical and political challenges that a revived antivivisectionist movement was mounting in the late 1970s and the 1980s.
