Most empirical work in human categorization has studied learning in either fully supervised or fully unsupervised scenarios. Most real-world learning scenarios, however, are semi-supervised: Learners receive a great deal of unlabeled information from the world, coupled with occasional experiences in which items are directly labeled by a knowledgeable source. A large body of work in machine learning has investigated how learning can exploit both labeled and unlabeled data provided to a learner. Using equivalences between models found in human categorization and (...) machine learning research, we explain how these semi-supervised techniques can be applied to human learning. A series of experiments are described which show that semi-supervised learning models prove useful for explaining human behavior when exposed to both labeled and unlabeled data. We then discuss some machine learning models that do not have familiar human categorization counterparts. Finally, we discuss some challenges yet to be addressed in the use of semi-supervised models for modeling human categorization. (shrink)

Montague and Kaplan began a revolution in semantics, which promised to explain how a univocal expression could make distinct truth-conditional contributions in its various occurrences. The idea was to treat context as a parameter at which a sentence is semantically evaluated. But the revolution has stalled. One salient problem comes from recurring demonstratives: "He is tall and he is not tall". For the sentence to be true at a context, each occurrence of the demonstrative must make a different truth-conditional contribution. (...) But this difference cannot be accounted for by standard parameter sensitivity. Semanticists, consoled by the thought that this ambiguity would ultimately be needed anyhow to explain anaphora, have been too content to posit massive ambiguities in demonstrative pronouns. This article aims to revived the parameter revolution by showing how to treat demonstrative pronouns as univocal while providing an account of anaphora that doesn't end up re-introducing the ambiguity.

W. V. Quine was quite simply the most distinguished analytic philosopher of the later half of the twentieth century. His celebrated attack on the analytic/synthetic tradition heralded a major shift away from the views of language descended from logical positivism. His most important book, Word and Object, introduced the concept of indeterminacy of radical translation, a bleak view of the nature of the language with which we ascribe thoughts and beliefs to ourselves and others. Quine is also famous for the (...) view that epistemology should be naturalized, that is conducted in a scientific spirit with the object of investigating the relationship between the inputs of experience and the outputs of belief. The eleven essays in this volume cover all the central topics of Quine's philosophy: the underdetermination of physical theory, analycity, naturalism, propositional attitudes, behaviorism, reference and ontology, positivism, holism and logic.

Those of us who take skepticism seriously typically have two relevant beliefs: (a) it’s plausible (even if false) that in order to know that I have hands I have to be able to epistemically neutralize, to some significant degree, some skeptical hypotheses, such as the brain-in-a-vat (BIV) one; and (b) it’s also plausible (even if false) that I can’t so neutralize those hypotheses. There is no reason for us to also think (c) that the BIV hypothesis, for instance, is plausible (...) or probably true. In order to take skepticism seriously it’s sufficient to hold (a) and (b); one need not hold (c). Indeed, philosophers who accept (a) and (b) never endorse (c). Show me a philosopher who suspects that he is a brain in a vat and I’ll show you someone who is deranged! That’s one thing that bothers undergraduates in philosophy. They object: why on earth do some philosophers take the BIV hypothesis to pose any threat at all to our beliefs given that those very same philosophers think that there’s no real chance that the BIV hypothesis is true? Sure, the BIV hypothesis is formally inconsistent with my belief that I have hands, so if the former is true then my belief is false. But so what? Why should that bare inconsistency matter so much? Is this strange attitude amongst philosophers the result of some logic fetish infecting the philosophical community? It is sometimes said that the skeptical hypotheses are not only inconsistent with our beliefs but are explanatory of our experiences, which is supposed to make them more of a threat. But students aren’t fooled: although the skeptical hypotheses may attempt to explain why our experience is as it is, it’s the kind of attempt appropriate for science fiction movies that are all special effects and virtually no plot. No one with any sense of reality will take the evil demon hypothesis to be even tenuously explanatory. (shrink)

The Greek word eoikos can be translated in various ways. It can be used to describe similarity, plausibility or even suitability. This book explores the philosophical exploitation of its multiple meanings by three philosophers, Xenophanes, Parmenides and Plato. It offers new interpretations of the way that each employs the term to describe the status of their philosophy, tracing the development of this philosophical use of eoikos from the fallibilism of Xenophanes through the deceptive cosmology of Parmenides to Plato's Timaeus. The (...) central premise of the book is that, in reflecting on the eoikos status of their accounts, Xenophanes, Parmenides and Plato are manipulating the contexts and connotations of the term as it has been used by their predecessors. By focusing on this continuity in the development of the philosophical use of eoikos, the book serves to enhance our understanding of the epistemology and methodology of Xenophanes, Parmenides and Plato's Timaeus.

To commemorate 40 years since the founding of the Journal of Business Ethics, the editors in chief of the journal have invited the editors to provide commentaries on the future of business ethics. This essay comprises a selection of commentaries aimed at creating dialogue around the theme The Ethics and Politics of Academic Knowledge Production. Questions of who produces knowledge about what, and how that knowledge is produced, are inherent to editing and publishing academic journals. At the Journal of Business (...) Ethics, we understand the ethical responsibility of academic knowledge production as going far beyond conventions around the integrity of the research content and research processes. We are deeply aware that access to resources, knowledge of the rules of the game, and being able to set those rules, are systematically and unequally distributed. One could ask the question “for whom is knowledge now ethical’”? (See the Burrell commentary.) We have a responsibility to address these inequalities and open up our journal to lesser heard voices, ideas, and ways of being. Our six commentators pursue this through various aspects of the ethics and politics of academic knowledge production. Working with MacIntyre’s scheme of practices and institutions, Andrew West provides commentary on the internal good of business ethics learning and education. Inviting us to step out of the cave, Christopher Michaelson urges a clear-eyed, unblinking focus on the purposes and audiences of business ethics scholarship. As developmental editor, Scott Taylor uncovers some of the politics of peer review with the aim of nurturing of unconventional research. Mike Hyman presents his idiosyncratic view of marketing ethics. In the penultimate commentary, Julie Nelson attributes difficulties in the academic positioning of the Business Ethics field to the hegemony of a masculine-centric model of the firm. And finally, Gibson Burrell provides a powerful provocation to go undercover as researcher-investigators in a parallel ethics of the research process. (shrink)

Beginning with the death of Socrates in 399 BC, and following the strand of philosophical inquiry through the centuries to recent figures such as Bertrand Russell and Wittgenstein, Bryan Magee's conversations with fifteen contemporary writers and philosophers provide an accessible and exciting account of Western philosophy and its greatest thinkers. With contributions from A. J. Ayer, Bernard Williams, Martha Nussbaum, Peter Singer, and John Searle, the book is not only an introduction to the philosophers of the past, but gives (...) an invaluable insight into the view and personalities of some of the most influential philosophers of the twentieth century.

After a period of inactivity, interest in explanationism as a thesis about the nature of epistemic justification has been renewed. Poston and McCain have both recently offered versions of explanationist evidentialism. In this paper, we pose two objections to explanationist evidentialism. First, explanationist evidentialism fails to state a sufficient condition for justification. Second, explanationist evidentialism implies a vicious regress.

:Since the advent of recombinant DNA technology, expectations about the potential for altering genes and controlling our biology at the fundamental level have been sky high. These expectations have gone largely unfulfilled. But though the dream of being able to control our biology is still far off, gene editing research has made enormous strides toward potential clinical use. This paper argues that when it comes to determining permissible uses of gene editing in one important medical context—germline intervention in reproductive medicine—issues (...) about enhancement and eugenics are, for the foreseeable future, a red herring. Current translational goals for gene editing research involve a different kind of editing than would be required to achieve manipulation of complex traits such as intelligence, and there are more pressing questions that need attention if clinical use of gene editing in reproductive medicine ever becomes a possibility.

In the language of second-order logic, first- and second-order variables are distinguished syntactically and cannot be grammatically substituted. According to a prominent argument for the deployment of these languages, these substitution failures are necessary to block the derivation of paradoxes that result from attempts to generalize over predicate interpretations. I first examine previous approaches which interpret second-order sentences using expressions of natural language and argue that these approaches undermine these syntactic restrictions. I then examine Williamson’s primitivist approach according to which (...) second-order sentences are not offered readings in a previously understood language. I argue that the syntactic restrictions alone do not block the derivation of the paradox, unless they are backed by a principled reason that the language cannot be expanded to allow the grammatical substitution of first- and second- order variables. I argue that there is neither a syntactic nor a semantic principle that prohibits such an expansion. (shrink)

This practical guide helps us identify the wrong beliefs about God we received from our families of origin and replace them with truth so we can embrace the abundant Christian life we long for.

The principle of compositionality requires that the meaning of a complex expression remains the same after substitution of synonymous expressions. Alleged counterexamples to compositionality seem to force a theoretical choice: either apparent synonyms are not synonyms or synonyms do not syntactically occur where they appear to occur. Some theorists have instead looked to Frege’s doctrine of “reference shift” according to which the meaning of an expression is sensitive to its linguistic context. This doctrine is alleged to retain the relevant claims (...) about synonymy and substitution while respecting the compositionality principle. Thus, Salmon (Philos Rev 115(4):415, 2006) and Glanzberg and King (Philosophers’ Imprint 20(2):1–29, 2020) offer occurrence-based accounts of variable binding, and Pagin and Westerståhl (Linguist Philos 33(5):381–415, 2010c) argue that an occurrence-based semantics delivers a compositional account of quotation. Our thesis is this: the occurrence-based strategies resolve the apparent failures of substitutivity in the same general way as the standard expression-based semantics do. So it is a myth that a Frege-inspired occurrence-based semantics affords a genuine alternative strategy. (shrink)

The distinction between germline and somatic gene editing is fundamental to the ethics of human gene editing. Multiple conferences of scientists, ethicists, and policymakers, and multiple professional bodies, have called for moratoria on germline gene editing, and editing of human germline cells is considered to be an ethical “red line” that either never should be crossed, or should only be crossed with great caution and care. However, as research on germline gene editing has progressed, it has become clear that not (...) all germline interventions are alike, and that these differences make a significant moral difference, when it comes to ethical questions about research, regulation, clinical application, and medical justification. In this paper, I argue that, rather than lumping all germline interventions together, we should distinguish between revising, correcting, and transferring genes, and I assess the consequences of this move for the ethics of gene editing.

Aristotle’s theory of human happiness in the Nicomachean Ethics explicitly depends on the claim that contemplation (theôria) is peculiar to human beings, whether it is our function or only part of it. But there is a notorious problem: Aristotle says that divine beings also contemplate. Various solutions have been proposed, but each has difficulties. Drawing on an analysis of what divine contemplation involves according to Aristotle, I identify an assumption common to all of these proposals and argue for rejecting it. (...) This allows a straightforward solution to the problem and there is evidence that Aristotle would have adopted it. (shrink)

This book develops a comprehensive framework for ethics in the helping professions based on bioethicist Bernard Gert's theory of common morality. The prevailing model of ethics education is built upon adherence to codes of ethics applied largely through the use of decision-making trees. While a firm understanding of a professions code of ethics and all relevant laws is essential to responsible practice, this approach to teaching ethics excludes the opportunity for students to acquire a holistic, and grounded understanding of moral (...) action. The framework proposed in this text moves beyond codes of ethics, and allows students to develop a cohesive sense of ethical reasoning that both validates their moral intuition and challenges moral assumptions. The theory of a common morality uses a systematic, step-by-step approach that readers and practitioners can apply to all questions of moral action and behaviour. While there is no such thing as a single right answer to any ethical question, by following this approach practitioners can confidently eliminate the bad decisions, allowing them to feel more secure in their decision and practice.

We tend to think that philosophical progress, to the extent that it exists, is a good thing. I agree. Even so, it has some surprising unfortunate consequences for the rationality of philosophical belief.

This virtual special issue of the Journal of Business Ethics is dedicated to the role that social theory and sociological research can play in understanding business ethics in the contemporary world. Articles have been selected for this virtual issue that highlight the insights provided by the long tradition of sociological theorising, that focus upon enduring social problems and which deal with particularly twenty-first century issues.

This is a revised and enlarged version of Bryan Magee's widely praised study of Schopenhauer, the most comprehensive book on this great philosopher. It contains a brief biography of Schopenhauer, a systematic exposition of his thought, and a critical discussion of the problems to which it gives rise and of its influence on a wide range of thinkers and artists. For this new edition Magee has added three new chapters and made many minor revisions and corrections throughout. This new (...) edition will consolidate the book's standing as the definitive study of Schopenhauer. (shrink)

A central dispute in understanding Frege’s philosophy concerns how the sense of a complex expression relates to the senses of its component expressions. According to one reading, the sense of a complex expression is a whole built from the senses of the component expressions. On this interpretation, Frege is an early proponent of structured propositions. A rival reading says that senses compose by functional application: the sense of a complex expression is the value of the function denoted by its functional (...) component for the arguments denoted by its remaining components. I argue that two non-negotiable Fregean theses entail that senses compose by functional application. One thesis is that referents compose by functional application. The other thesis is that an expression in an indirect context refers to its customary sense. (shrink)

Design of clinical trials for germline gene editing stretches current accepted standards for human subjects research. Among the challenges involved is a set of issues concerningintergenerational monitoring—long-term follow-up study of subjects and their descendants. Because changes made at the germline would be heritable, germline gene editing could have adverse effects on individuals’ health that can be passed on to future generations. Determining whether germline gene editing is safe and effective for clinical use thus may require intergenerational monitoring. The aim of (...) this paper is to identify and argue for the significance of a set of ethical issues raised by intergenerational monitoring in future clinical trials of germline gene editing. Though long-term, multigenerational follow-up study of this kind is not without precedent, intergenerational monitoring in this context raises unique ethical challenges, challenges that go beyond existing protocols and standards for human subjects research. These challenges will need to be addressed if clinical trials of germline gene editing are ever pursued. (shrink)

This article argues that economic crises are incompatible with the realisation of non-domination in capitalist societies. The ineradicable risk that an economic crisis will occur undermines the robust security of the conditions of non-domination for all citizens, not only those who are harmed by a crisis. I begin by demonstrating that the unemployment caused by economic crises violates the egalitarian dimensions of freedom as non-domination. The lack of employment constitutes an exclusion from the social bases of self-respect, and from a (...) practice of mutual social contribution crucial to the intersubjective affirmation of one’s status. While this argument shows that republicans must be concerned about economic crises, I suggest a more powerful argument can be grounded in the republican requirement that freedom must be robust. The systemic risk of economic crisis constitutes a threat to the conditions of free citizenship that cannot be nullified using policy mechanisms. As a result, republicans appear to be faced with the choice of revising their commitments or rejecting the possibility that republican freedom can be robustly secured in capitalist societies.

Despite the increase in global research on health inequalities, more needs to be done to strengthen efforts to inform local interventions. In this article, we ask what determines the local capacity to engage in research on health inequalities. A bibliometric analysis identified Spain as the 10th highest global contributor to this research field (1966–2015), yet a significant proportion of this production was affiliated to just a few institutions in Barcelona. How and why has the city produced so much health inequalities (...) research over four decades? A realist explanatory case study was conducted to test and refine six causal mechanisms, and identify the contextual conditions that might have activated them to generate this outcome. Data was triangulated from 10 semi-structured interviews, and scientific and grey literature. Our findings confirmed that several of our proposed mechanisms - functioning under certain conditions over time - explain the large volume of health inequalities research in Barcelona. Based on these findings, key lessons from the city's experience are suggested. Further research is needed on this topic. (shrink)

How secular is contemporary society? Are pockets of sectarianism embedded in societies of developed countries? This timely book examines the interweaving of politics and religion, and of tradition and innovation in a variety of cultural settings. Eminent scholars from four continents examine here current turmoil in religious beliefs, practices, and organization--not only in the Western world, but in South America, Africa, South Asia, New Zealand, and Japan. They scrutinize evidence of religious change, decline, and revival; investigate challenges posed by new (...) religious movements; and locate religious change and conflict in the context of broader shifts in consciousness and culture. Contributors include Richard Fenn, Phillip E. Hammond, David Martin, Philip Rieff, Roland Robertson, and Mark Schibley. With its focus on the interplay of secularization, rationalism, and sectarianism, this work offers a fitting tribute to Bryan Wilson, who has made so many contributions to the sociological understanding of these phenomena.

Although the mapping between form and meaning is often regarded as arbitrary, there are in fact well-known constraints on words which are the result of functional pressures associated with language use and its acquisition. In particular, languages have been shown to encode meaning distinctions in their sound properties, which may be important for language learning. Here, we investigate the relationship between semantic distance and phonological distance in the large-scale structure of the lexicon. We show evidence in 100 languages from a (...) diverse array of language families that more semantically similar word pairs are also more phonologically similar. This suggests that there is an important statistical trend for lexicons to have semantically similar words be phonologically similar as well, possibly for functional reasons associated with language learning.

Aristotle thinks that happiness is an activity---it consists in doing something---rather than a feeling. It is the best activity of which humans are capable and is spread out over the course of a life. But what kind of activity is it? Some of his remarks indicate that it is a single best kind of activity, intellectual contemplation. Other evidence suggests that it is an overarching activity that has various virtuous activities, ethical and intellectual, as parts. At stake are questions about (...) how we should live and the correct balance of theoretical and practical activity. Numerous interpreters have sharply disagreed about Aristotle's answers to such questions. This book offers a fundamentally new approach to determining what kind of activity Aristotle thinks happiness is, one that challenges widespread assumptions that have until now prevented a dialectically satisfactory interpretation. This approach displays the boldness and systematicity of Aristotle's practical philosophy. (shrink)

Este artigo investiga as diferentes concepções de “Sujeito” de acordo com o corpus teórico do filósofo Paul B. Preciado. As categorias analisadas são: os processos subjetivos e técnicos de sujeição social e servidão maquínica na era farmacopornográfica; o sujeito Playboy e petrosexorracial; a Multidão, seus múltiplos devires e as micropolíticas de resistência à opressão; a metamorfose dos sujeitos em agentes revolucionários e os simbiontes políticos, postulados por Preciado em seu mais recente livro publicado, Dysphoria mundi. Como Preciado articula todas estas (...) concepções, considerando ainda as linhas de fuga da submissão, isto é, o horizonte filosófico de resistência onto-epístemo-política, metamorfose e até a possível superação da dominação capitalística? Os procedimentos metodológicos foram baseados na pesquisa bibliográfica (livros, artigos e crônicas), de modo a evidenciar o contraste, as semelhanças, diferenças e interstícios entre a teoria de Preciado e as suas principais referências. Os resultados obtidos indicam uma linearidade consistente entre-categorias, os desafios em materializar as teorias revolucionárias na realidade cotidiana, bem como estratégias práticas que contribuem para a organização ontopolítica proposta por Preciado.

Philosophers ask just whose expression, if anyone’s, we hear in lyric poetry. Walton provides a novel possibility: it’s the reader who “uses” the poem (just as a speech giver uses a speech) who makes the language expressive. But worries arise once we consider poems in particular social or political settings, those which require a strong self-other distinction, or those with expressions that should not be disassociated from the subjects whose experience they draw from. One way to meet this challenge is (...) to consider the poem expressive of a plural subject, which frees us from looking for a particular individual whose voice we hear in the work, whether she be fictional or actual. Some lyrics give voice to a group whose experience is attended to in the work. This may be done through a posited fictional speaker, but the ontology of the speaker is shown to be less important. Attending to a group whose concerns are voiced allows us to explain how poems can manage to address our-worldly concerns even when lacking actual persons whose expressions we encounter in the poems.

To contribute to the continuing challenge of explaining how managers identify stakeholders and assess their salience, in this article, we chronicle the history, assess the impact, and evaluate the possibilities opened by Mitchell, Agle, and Wood (MAW-1997). We do so through two types of qualitative analysis, and also through utilizing a quantitative network analysis tool. The first qualitative analysis categorizes the major contributions of the most influential papers succeeding MAW-1997; the second identifies and compares the relevant issues with MAW-1997 at (...) the time of initial publication and today. We apply main path analysis, a quantitative tool, to map how this scholarly domain has evolved. These three analyses robustly depict the impact of MAW-1997 and the ensuing scholarly conversation, and they enable us to illustrate the current state and trajectory of stakeholder identification and salience scholarship. We close by discussing pressing topics related to the broader body of stakeholder theory literature. (shrink)

If you retain your belief upon learning that a large number and percentage of your recognized epistemic superiors disagree with you, then what happens to the epistemic status of your belief? I investigate that theoretical question as well has the applied case of philosophical disagreement—especially disagreement regarding purely philosophical error theories, theories that do not have much empirical support and that reject large swaths of our most commonsensical beliefs. I argue that even if all those error theories are false, either (...) (a) the average philosopher’s true commonsensical beliefs are epistemically impoverished, or (b) a good portion of philosophy is bunk and philosophers should give up most of their error theories despite the fact that their supporting arguments are generally as good as or even better than other philosophical arguments.
