The introduction of massive parallelism and the renewed interest in neural networks gives a new need to evaluate the relationship of symbolic processing and artificial intelligence. The physical symbol hypothesis has encountered many difficulties coping with human concepts and common sense. Expert systems are showing more promise for the early stages of learning than for real expertise. There is a need to evaluate more fully the inherent limitations of symbol systems and the potential for programming compared with training. This can (...) give more realistic goals for symbolic systems, particularly those based on logical foundations. (shrink)

Parental expectations have long been studied as a factor in increasing adolescent educational aspirations, often linking these expectations to parental level of education and involvement in academic endeavours. This study further explores this relationship in a statewide Midwestern sample of parents and their adolescent children. Regression analysis and independent samples t?tests were used to predict adolescent aspirations and compare groups. Results suggest that adolescent educational aspirations can to some degree be predicted by parental expectations. Parents reported high expectations for their (...) children despite low levels of personal educational attainment. However, these high expectations were buffered by a reported unfamiliarity with college requirements and an expressed concern about college affordability and limited awareness of financial aid opportunities. Limitations and suggestions for future research and intervention are discussed. (shrink)

This paper develops a precise understanding of the thesis of moral encroachment, which states that the epistemic status of an opinion can depend on its moral features. In addition, I raise objections to existing accounts of moral encroachment. For instance, many accounts fail to give sufficient attention to moral encroachment on credences. Also, many accounts focus on moral features that fail to support standard analogies between pragmatic and moral encroachment. Throughout the paper, I discuss racial profiling as a case study, (...) arguing that moral encroachment can help us identify one respect in which racial profiling is epistemically problematic.

Computer simulations of the formation and evolution of large-scale structure in the universe are integral to the enterprise of modern cosmology. Establishing the reliability of these simulations has been extremely challenging, primarily because of epistemic opacity. In this setting, robustness analysis defined by requiring converging outputs from a diverse ensemble of simulations is insufficient to determine simulation validity. We propose an alternative path of structured code validation that applies eliminative reasoning to isolate and reduce possible sources of error, a potential (...) path that is already being explored by some cosmologists.

We construct logical languages which allow one to represent a variety of possible types of changes affecting the information states of agents in a multi-agent setting. We formalize these changes by defining a notion of epistemic program. The languages are two-sorted sets that contain not only sentences but also actions or programs. This is as in dynamic logic, and indeed our languages are not significantly more complicated than dynamic logics. But the semantics is more complicated. In general, the semantics of (...) an epistemic program is what we call aprogram model. This is a Kripke model of ‘actions’,representing the agents' uncertainty about the current action in a similar way that Kripke models of ‘states’ are commonly used in epistemic logic to represent the agents' uncertainty about the current state of the system. Program models induce changes affecting agents' information, which we represent as changes of the state model, called epistemic updates. Formally, an update consists of two operations: the first is called the update map, and it takes every state model to another state model, called the updated model; the second gives, for each input state model, a transition relation between the states of that model and the states of the updated model. Each variety of epistemic actions, such as public announcements or completely private announcements to groups, gives what we call an action signature, and then each family of action signatures gives a logical language. The construction of these languages is the main topic of this paper. We also mention the systems that capture the valid sentences of our logics. But we defer to a separate paper the completeness proof. (shrink)

This paper argues that several leading theories of subjunctive conditionals are incompatible with ordinary intuitions about what credences we ought to have in subjunctive conditionals. In short, our theory of subjunctives should intuitively display semantic humility, i.e. our semantic theory should deliver the truth conditions of sentences without pronouncing on whether those conditions actually obtain. In addition to describing intuitions about subjunctive conditionals, I argue that we can derive these ordinary intuitions from justified premises, and I answer a possible worry (...) for my derivation by refuting a subjunctive triviality result modeled on (Lewis 1976). I conclude that the debate over the correct theory of subjunctive conditionals requires settling meta-philosophical questions about the relative value of various virtues of first-order theories of subjunctive conditionals.

Interventions that are designed to stem plagiarism do not always override the motivation of individuals to cheat and, therefore, may not diminish misconduct. To inform more effective approaches, we conducted a systematic review to clarify the psychological causes of plagiarism. This review of 83 empirical papers showed that a specific blend of circumstances may foster plagiarism: an emphasis on competition and success rather than development and cooperation coupled with impaired resilience, limited confidence, impulsive tendencies, and biased cognitions. Fortunately, whenever students (...) feel their life and studies align to their future aspirations, many of these circumstances tend to dissipate. (shrink)

The notion that human activity can be characterised in terms of dynamic systems is a well-established alternative to motor schema approaches. Key to a dynamic systems approach is the idea that a system seeks to achieve stable states in the face of perturbation. While such an approach can apply to physical activity, it can be challenging to accept that dynamic systems also describe cognitive activity. In this paper, we argue that creativity, which could be construed as a ‘cognitive’ activity par (...) excellence, arises from the dynamic systems involved in jewellery making. Knowing whether an action has been completed to a ‘good’ standard is a significant issue in considering acts in creative disciplines. When making a piece of jewellery, there a several criteria which can define ‘good’. These are not only the aesthetics of the finished piece but also the impact of earlier actions on subsequent ones. This suggests that the manner in which an action is coordinated is influenced by the criteria by which the product is judged. We see these criteria as indicating states for the system, e.g. in terms of a space of ‘good’ outcomes and a complementary space of ‘bad’ outcomes. The skill of the craftworker is to navigate this space of available states in such a way as to minimise risk, effort and other costs and maximise benefit and quality of the outcome. In terms of postphenomonology, this paper explores Ihde’s human-technology relations and relates these to the concepts developed here. (shrink)

When the history of life on earth is viewed as a history of cell division, all of life becomes a single cell lineage. The growth and differentiation of this lineage in reciprocal interaction with its environment can be viewed as a developmental process; hence the evolution of life on earth can also be seen as the development of life on earth. Here, in reviewing this field, some potentially fruitful research directions suggested by this change in perspective are highlighted. Variation and (...) selection become, for example, bidirectional information flows between scales, while the notions of “cooperation” and “competition” become scale relative. The language of communication, inference, and information processing becomes more useful than the language of causation to describe the interactions of both homogeneous and heterogeneous living systems at any scale. Emerging scale‐free theoretical frameworks such as predictive coding and active inference provide conceptual tools for reconceptualizing biology as the study of a unified, multiscale dynamical system.

Among the many striking features of the philosophy of the Zhuāngzǐ is that it advocates a life unperturbed by emotions, including even pleasurable, positive emotions such as joy or delight. Many of us see emotions as an ineluctable part of life, and some would argue they are a crucial component of a well-developed moral sensitivity and a good life. The Zhuangist approach to emotion challenges such commonsense views so radically that it amounts to a test case for the fundamental plausibility (...) of the Daoist ethical orientation: If the Zhuangist stance on emotion is untenable, then other aspects of Daoist ethics may founder as well. In this essay, I explore what I call a Zhuangist ‘Virtuoso View’ of emotion and its connections with human agency, attempting to show that at least one version of a Zhuangist approach to emotion passes the ‘basic plausibility’ test. I begin by describing the Virtuoso View and sketching its theoretical foundation, which involves claims about human agency, the self, psychophysical hygiene, the good life, epistemology, and metaphysics. Next, I defend the Virtuoso View against three objections, namely that it abandons intentionality, that it interferes with a good life, and that it yields a schizophrenic conception of agency. I argue for three major theses. First, the Virtuoso View is easily intelligible and largely defensible. Second, it reflects a crucial insight into a fundamental dichotomy at the core of human agency: the unavoidable conflict within a self-aware human agent between an internal, engaged perspective and an external, detached one. Third, I suggest that certain problems or conflicts arising from the Virtuoso View actually reflect inherent features of the human predicament and thus are not mere conceptual defects. Hence even if we do not find the Virtuoso View wholly convincing, we can nevertheless gain much insight from it. (shrink)

According to Manuel Davenport, “The best humorists--Mark Twain, Will Rogers, Bob Hope, and Mort Sahl--share [a] mixture of detachment and desire, eagerness to believe, and irreverence concerning the possibility of certainty. And when they become serious about their convictions--as Twain did about colonialism…they cease to be humorous” (p. 171). I agree with the first part, but not the second. Humor does require disengagement, but not completely such that one has no emotional interest in the subject of the humor. Humor does (...) require some degree of commitment to value, but, as Davenport rightly notes, it “despairs of absolutes.” Following Bertrand Russell, “humorous” and “serious” are not antonyms. Davenport does not provide examples of Twain’s attempts at satire that fail to be humorous due to being serious. I will examine some of the very serious issues Twain addresses through irony and humor, and make the case that his commentary and argument, though serious, is still funny while not falling into frivolity. There is a philosophical thread running through his scathing humor, and it largely centers around his raising awareness about, and then deflating, what I would call a “spirit of seriousness”, borrowing from Jean-Paul Sartre and Simone De Beauvoir. For De Beauvoir, expanding on Sartre’s conception, a spirit of seriousness manifests from serious people who attempt to find comfort in the firm, unchanging foundations and values that are seen to be pre-determined, and thus unquestionable. In Twain’s case, it is arrogance and a presumed sense of certitude. This destructive combination sustains many of the institutions (some of them quite “peculiar”) that he attacks: racism, slavery, colonialism, excesses of capitalism, and the often dogmatic and oppressive nature of organized religion: “What gets us into trouble is not what we don’t know; it’s what we know for sure that just ain’t so.” Complacency, self-satisfaction, disinclination to self-monitoring, all lead to closed mode, or rather, to sustaining a serious mode which can spillover into a “spirit of seriousness” if not checked. The quickest path to a feeling of being certain is cultivated ignorance, where doubt and confusion, ambiguity and fluidity are glossed over. This feeling or attitude, the “spirit of seriousness”, is what Twain confronts with serious humor, motivating his readers to consider where their ideals and reality contradict. (shrink)

Foucault and Social Dialogue; Beyond Fragmentation is a compelling yet extremely clear investigation of these options and offers a new way forward. Christopher Falzon argues that the proper alternative to foundationalism is not fragmentation but dialogue and that such a dialogical picture can be found in the work of Michel Foucault. Such a reading of Foucault allows us to see, for the first time, the ethical and political position implicit in Foucault's work and how his work contributes to the larger (...) debate concerning the death of man.

Thought experiments are responsible for several major intellectual revolutions throughout history. Given their importance it is surprising that they are not used more frequently as teaching tools. The history of thought experiments, their applications to disciplines across academia, and their practical classroom uses are examined in this book.

In previous work we have developed Property Theory with Curry Typing (PTCT), an intensional first-order logic for natural language semantics. PTCT permits fine-grained specifications of meaning. It also supports polymorphic types and separation types. We develop an intensional number theory within PTCT in order to represent proportional generalized quantifiers like "most", and we suggest a dynamic type-theoretic approach to anaphora and ellipsis resolution. Here we extend the type system to include product types, and use these to define a permutation function (...) that generates underspecified scope representations within PTCT. We indicate how filters can be added to encode constraints on possible scope readings. Our account offers several important advantages over other current theories of underspecification. (shrink)

RÉSUMÉ: Une justification d’institutions morales ou politiques doit fournir aux gens une motivation pour agir en conformité avec ses diktats. Cela étant admis, je soutiens que le contractualisme est la seule méthode plausible par laquelle une telle justification puisse être fournie. Les contractualistes soutiennent que les institutions morales ou politiques sont justifiées dans la mesure où elles seraient le résultat d’une entente conclue par des agents rationnels. Les agents rationnels agissent de façon à maximiser leur utilité attendue. Lorsque tous les (...) facteurs sont pris en considération, une entente conclue par des agents rationnels doit donc maximiser leur utilité attendue. À partir de cela, et de l’observation du lieu commun selon lequel des personnes différentes ont des préférences différentes, je soutiens que les justifications contractualistes sont relatives à la fois sur le plan normatif et sur le plan méta-éthique. Tant les règles ainsi justifiées que la procédure employée pour produire la justification doivent être identifiées relativement à des populations particulières. (shrink)

It is somewhat popular to claim that an argument justifies its conclusion only if the subject has a justified belief that the premise supports the conclusion. Andrew Cling gives a novel argument for this requirement, which he calls “(JCC).” He claims that any otherwise plausible theory that rejects (JCC) is committed to distinguishing arbitrarily between arguments that provide doxastic justification for their conclusions and those that don’t. In this paper, I show that Cling’s argument fails, and I explain how the (...) opponent of (JCC) can justify her apparently arbitrary distinctions. (shrink)

Why ever assert clarity? If It is clear that p is true, then saying so should be at best superfluous. Barker and Taranto (2003) and Taranto (2006) suggest that asserting clarity reveals information about the beliefs of the discourse participants, specifically, that they both believe that p . However, mutual belief is not sufficient to guarantee clarity ( It is clear that God exists ). I propose instead that It is clear that p means instead (roughly) 'the publicly available evidence (...) justifies concluding that p '. Then what asserting clarity reveals is information concerning the prevailing epistemic standard that determines whether a body of evidence is sufficient to justify a claim. If so, the semantics of clarity constitutes a grammatical window into the discourse dynamics of inference and skepticism. (shrink)

Action research began as an ambitious epistemological and social intervention. As the concept has become reified, packaged for methodology textbooks and professional development workshops, it has degenerated into a cure that may be worse than the disease. The point is not the trivial one that action research, like any practice, sometimes shows up in cheap or corrupt forms. The very idea that action research already exists as a live option is mystifying, distracting us from the deep challenge that action research (...) ultimately represents. Though Joseph Schwab is sometimes credited as a forerunner of action research, it is likely that he would see the new talk of ‘the teacher as researcher’ as indicative of the very epitomization of which he warned. Dewey’s new conception of knowledge, action, and communication – and the vision of the teacher as learner it entails – requires nothing short of a radical rethinking of teaching and inquiry, schooling and teacher education. This essay recalls the promise of... (shrink)

The Ollivier–Poulin–Zurek definition of objectivity provides a philosophical basis for the environment as witness formulation of decoherence theory and hence for quantum Darwinism. It is shown that no account of the reference of the key terms in this definition can be given that does not render the definition inapplicable within quantum theory. It is argued that this is not the fault of the language used, but of the assumption that the laws of physics are independent of Hilbert-space decomposition. All evidence (...) suggests that this latter assumption is true. If it is, decoherence cannot explain the emergence of classicality. (shrink)

J. S. Mill is typically thought of as a liberal utilitarian disciple of Jeremy Bentham, and in other readings as a modern Socratic or even a modern Epicurean. Mill and the Epicureans are alike in several respects: they theorize personal freedom and active character versus determinism and passivity, they oppose excessive love and praise friendship, and they are critical of traditional religiosity. In spite of these similarities, Mill and the Epicureans have a different conception of active character and citizenship, stemming (...) from a difference in first principles. Mill's philosopher does not share the Epicurean aim of untroubledness (ataraxia), and Mill accepts the demanding task of educating and regenerating a mass democratic society. Below, I assess Mill's troubled hedonism, that is, his acceptance of often intense and long-term mental perturbations, justified by a decidedly non-Epicurean social reform project. (shrink)

Although Kant's attempts in the Groundwork of the Metaphysics of Morals to derive statements of specific duties from the categorical imperative have received much attention, there is still disagreement over the strategies of particular derivations, the status of the auxiliary assumptions employed therein, and the principles at work in the derivations generally. Yet an understanding of these matters is indispensable for a proper understanding of the Groundwork and bears on a much wider class of ethical theories as well. My aim (...) here is to provide an account of the derivations and their auxiliary premises that explains both the strategy behind the derivations generally and the details of Kant's specific examples. In particular, I shall argue that the widespread view that the premises of the derivations are empirical is mistaken and that their conclusions are thus more general than is often supposed. (shrink)

_ The Subject of Human Being_ discusses the basic powers of human kind arising from the foundation of the biological brain and manifesting in extraordinary psychological and social capacities and developments. The book consolidates theoretical insights into social ontology from several thinkers, whose profound advances toward understanding the relationship between individuals and society ought to revolutionize social theory as understood and practiced in the social sciences and humanities. Drawing from critical realist social theory developed by Bhaskar and Margaret Archer, John (...) Searle’s philosophy of mind and social ontology, Husserlean and Sartrean phenomenology of consciousness, and Lacanian and existential psychoanalytic theory, the book seeks to portray a unified social ontology that is materialist, emergent, realist, dialectical, processual, and liberatory. Offering a dialectical and progressive view of human being to counter the forces of exploitation and division inflicted on human kind and the ecosystems in which we reside, this book is essential reading for students and scholars of critical realism, philosophy and sociology.

In this lecture, I present a sketch of how action and agency are conceived of in pre-Qín 先秦, or classical, Chinese thought, along the way drawing some contrasts with familiar Western conceptions of action. I will also comment briefly on how the ideas I present might affect our interpretation of early Chinese texts and how they might help us to relate early Chinese thought to contemporary action theory and ethics.

This paper explores relational syllogistic logics, a family of logical systems related to reasoning about relations in extensions of the classical syllogistic. These are all decidable logical systems. We prove completeness theorems and complexity results for a natural subfamily of relational syllogistic logics, parametrized by constructors for terms and for sentences.

This article enlarges classical syllogistic logic with assertions having to do with comparisons between the sizes of sets. So it concerns a logical system whose sentences are of the following forms: Allxareyand Somexarey, There are at least as manyxasy, and There are morexthany. Herexandyrange over subsets (not elements) of a giveninfiniteset. Moreover,xandymay appear complemented (i.e., as$\bar{x}$and$\bar{y}$), with the natural meaning. We formulate a logic for our language that is based on the classical syllogistic. The main result is a soundness/completeness theorem. (...) There are efficient algorithms for proof search and model construction. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:On Wu-wei as a Unifying MetaphorChris FraserEffortless Action: Wu-wei as Conceptual Metaphor and Spiritual Ideal in Early China. By Edward Slingerland. New York: Oxford University Press, 2003. Pp. xii + 352. $60.00.This provocative work is the most ambitious general study of pre-Qin thought to appear in more than a decade. It deals with what is increasingly recognized as one of the period's key themes, the ethical ideal of perfected (...) action and the processes of cultivation, or uncultivation, by which it might be achieved. The book has two specific aims, one substantive, one methodological (p. vii). The substantive aim is to show that the notion of wu-wei, which Slingerland renders as "effortless action," functioned as a shared ideal and problematic for both Daoists and Confucians and that internal tensions in this ideal motivated much of the development of Warring States thought (p. 5). The methodological aim is to illustrate the fruitfulness of conceptual-metaphor theory, familiar from the work of Lakoff and Johnson, by employing it to articulate and support the book's substantive theses (p. vii).For Slingerland, wu-wei is "a state of personal harmony in which actions flow freely and instantly from one's spontaneous inclinations... and yet nonetheless accord perfectly with the dictates of the situation at hand, display an almost supernatural efficacy, and (in the Confucian context at least) harmonize with the demands of conventional morality" (p. 7). Slingerland expands on this characterization in various ways, without making it entirely clear how all the features he identifies fit together. On the one hand, he explains that wu-wei is a phenomenological feature of the agent's subjective mental state: "wu-wei properly refers not to what is actually happening (or not happening) in the realm of observable action but rather to... the phenomenological state of the doer" (p. 7), primarily one of effortlessness and unselfconsciousness (pp. 29-33). But wu-wei is also "action that... accords in every particular with the normative order of the cosmos" (p. 5), so beyond its phenomenological features, it must include an objective normative component as well. Another remark suggests that wu-wei fundamentally is not a phenomenological state after all, since "it represents not a transitory state but rather a set of dispositions" (p. 7). Probably these various statements are meant to emphasize that the crux of wu-wei is to achieve and sustain a certain sort of psychological state, which then reliably generates effortless, normatively appropriate, efficacious action.The phrase 'wu-wei' plays essentially no role in Confucian texts and is absent from large chunks of the Zhuangzi. So Slingerland's thesis that wu-wei is the joint [End Page 97] ideal of both Daoist and Confucian thought faces a daunting justificatory challenge, which he proposes to meet by applying conceptual metaphor theory (p. 10). On his interpretation, wu-wei is not to be understood literally, as "non-doing," since in the state denoted by wu-wei, the agent is not actually inactive, doing nothing at all (p. 11). This gap between literal meaning and actual reference indicates that the term 'wu-wei' functions metaphorically, referring to "a metaphorically conceived situation" in which an action occurs even though the agent exerts no effort (p. 11). Slingerland hypothesizes that wu-wei became a technical term for effortless action because it is the most general of a network of conceptual metaphors for effortlessness and unselfconsciousness, including families of metaphors for "following" (p. 29), "ease" (p. 30), and "forgetting" (p. 33). This network expresses a unified, "deeper conceptual structure," appeal to which justifies the claim that "apparently diverse ideals of perfected action" are in fact articulations and developments of a single metaphorically conceived ideal, though the term denoting it—'wu-wei'—may not appear in a particular text (p. 11).Once we have a grip on the conceptual structure of wu-wei through the families of metaphors that constitute it, we can identify wu-wei as a central problematic of pre-Qin thought and trace its development by examining the use of these metaphors in texts from the Book of Odes and the Book of History (chapter 1) through the Xunzi (chapter 7). Each... (shrink)

The behaviour of presupposition triggers in human language has been extensively studied and given rise to many distinct theoretical proposals. One intuitively appealing way of characterising presupposition is to argue that it constitutes backgrounded meaning, which does not contribute to updating the conversational record, and consequently may not be challenged or refuted by discourse participants. However, there are a wide range of presupposition triggers, some of which can systematically be used to introduce new information. Is there, then, a clear psychological (...) distinction between presupposition and assertion? Do certain expressions vacillate between presupposing and asserting information? And is information backgrounding a categorical or a gradient phenomenon? In this paper we argue for the value of experimental methods in addressing these questions, and present a pilot study demonstrating backgrounding effects of presupposition triggers, and suggesting their gradience in nature. We discuss the implications of these findings for theoretical categorisations of presupposition triggers. (shrink)

BackgroundDeciding whether to resuscitate extremely preterm infants (EPIs) is clinically and ethically problematic. The aim of the study was to understand neonatologists’ clinical–ethical decision-making for resuscitation of EPIs.MethodsWe conducted a qualitative study in Belgium, following a constructivist account of the Grounded Theory. We conducted 20 in-depth, face-to-face, semi-structured interviews with neonatologists. Data analysis followed the qualitative analysis guide of Leuven.ResultsThe main principles guiding participants’ decision-making were EPIs’ best interest and respect for parents’ autonomy. Participants agreed that justice as resource allocation (...) should not be considered in resuscitation decision-making. The main ethical challenge for participants was dealing with the conflict between EPIs’ best interest and respect for parents’ autonomy. This conflict was most prominent when parents and clinicians disagreed about births within the gray zone (24–25 weeks). Participants’ coping strategies included setting limits on extent of EPI care provided and rigidly following established guidelines. However, these strategies were not always feasible or successful. Although rare, these situations often led to long-lasting moral distress.ConclusionsParticipants’ clinical–ethical reasoning for resuscitation of EPIs can be mainly characterized as an attempt to balance EPIs’ best interest and respect for parents’ autonomy. This approach could explain why neonatologists considered conflicts between these principles as their main ethical challenge and why lack of resolution increases the risk of moral distress. Therefore, more research is needed to better understand moral distress in EPI resuscitation decisions.Clinical Trial Registration: The study received ethical approval from the ethics committee of UZ/ku Leuven (S62867). Confidentiality of personal information and anonymity was guaranteed in accordance with the General Data Protection Regulation of 25 May 2018. (shrink)
