Human languages vary in many ways but also show striking cross-linguistic universals. Why do these universals exist? Recent theoretical results demonstrate that Bayesian learners transmitting language to each other through iterated learning will converge on a distribution of languages that depends only on their prior biases about language and the quantity of data transmitted at each point; the structure of the world being communicated about plays no role (Griffiths & Kalish, , ). We revisit these findings and show that when (...) certain assumptions about the relationship between language and the world are abandoned, learners will converge to languages that depend on the structure of the world as well as their prior biases. These theoretical results are supported with a series of experiments showing that when human learners acquire language through iterated learning, the ultimate structure of those languages is shaped by the structure of the meanings to be communicated.

This article explores some of the philosophical implications of the Bayesian modeling paradigm. In particular, it focuses on the ramifications of the fact that Bayesian models pre‐specify an inbuilt hypothesis space. To what extent does this pre‐specification correspond to simply ‘‘building the solution in''? I argue that any learner must have a built‐in hypothesis space in precisely the same sense that Bayesian models have one. This has implications for the nature of learning, Fodor's puzzle of concept acquisition, and the role (...) of modeling in cognitive science. (shrink)

Everyday reasoning requires more evidence than raw data alone can provide. We explore the idea that people can go beyond this data by reasoning about how the data was sampled. This idea is investigated through an examination of premise non-monotonicity, in which adding premises to a category-based argument weakens rather than strengthens it. Relevance theories explain this phenomenon in terms of people's sensitivity to the relationships among premise items. We show that a Bayesian model of category-based induction taking premise sampling (...) assumptions and category similarity into account complements such theories and yields two important predictions: First, that sensitivity to premise relationships can be violated by inducing a weak sampling assumption; and second, that premise monotonicity should be restored as a result. We test these predictions with an experiment that manipulates people's assumptions in this regard, showing that people draw qualitatively different conclusions in each case. (shrink)

Jones & Love (J&L) contend that the Bayesian approach should integrate process constraints with abstract computational analysis. We agree, but argue that the fundamentalist/enlightened dichotomy is a false one: Enlightened research is deeply intertwined with the basic, fundamental work upon which it is based.

This interdisciplinary new work explores one of the central theoretical problems in linguistics: learnability. The authors, from different backgrounds---linguistics, philosophy, computer science, psychology and cognitive science-explore the idea that language acquisition proceeds through general purpose learning mechanisms, an approach that is broadly empiricist both methodologically and psychologically. Written by four researchers in the full range of relevant fields: linguistics, psychology, computer science, and cognitive science, the book sheds light on the central problems of learnability and language, and traces their implications (...) for key questions of theoretical linguistics and the study of language acquisition.

It is widely held that children’s linguistic input underdetermines the correct grammar, and that language learning must therefore be guided by innate linguistic constraints. Here, we show that a Bayesian model can learn a standard poverty‐of‐stimulus example, anaphoric one, from realistic input by relying on indirect evidence, without a linguistic constraint assumed to be necessary. Our demonstration does, however, assume other linguistic knowledge; thus, we reduce the problem of learning anaphoric one to that of learning this other knowledge. We discuss (...) whether this other knowledge may itself be acquired without linguistic constraints. (shrink)

We often talk of people as being more or less imaginative than one another – as being better or worse at imagining – and we also compare various feats of imagination to one another in terms of how easy or hard they are. Facts such as these might be taken to suggest that imagination is often implicitly understood as a skill. This implicit understanding, however, has rarely (if ever) been made explicit in the philosophical literature. Such is the task of (...) this chapter. I first attempt to flesh out several conditions for an activity to count as a skill. I then attempt to show how imagination can meet such conditions. The chapter concludes with an attempt to answer various worries that might be raised to the claim that imagination should be thought of as a skill. (shrink)

The challenge of handling fictional discourse is to find the best way to resolve the apparent inconsistencies in our ways of speaking about fiction. A promising approach is to take at least some such discourse to involve pretense, but does all fictional discourse involve pretense? I will argue that a better, less revisionary, solution is to take internal and fictionalizing discourse to involve pretense, while allowing that in external critical discourse, fictional names are used seriously to refer to fictional characters. (...) I then address two objections to such realist theories of fiction: One, that they can’t adequately account for the truth of singular nonexistence claims involving fictional names, and two, that accepting that there are fictional characters to which we refer is implausible or ontologically profligate.

Bailey (2021) offers a clever argument for the compatibility of determinism and moral responsibility based on the nature of intrinsic intentions. The argument is mistaken on two counts. First, it is invalid. Second, even setting that first point aside, the argument proves too much: we would be blameworthy in paradigm cases of non-blameworthiness. I conclude that we cannot reason from intentions to responsibility solely from the “inside out”—our possessing a blameworthy intention cannot tell us whether this intention is also blameworthy (...) in deterministic worlds.

The most widely debated conception of democracy in recent years is deliberative democracy--the idea that citizens or their representatives owe each other mutually acceptable reasons for the laws they enact. Two prominent voices in the ongoing discussion are Amy Gutmann and Dennis Thompson. In Why Deliberative Democracy?, they move the debate forward beyond their influential book, Democracy and Disagreement.What exactly is deliberative democracy? Why is it more defensible than its rivals? By offering clear answers to these timely questions, Gutmann and (...) Thompson illuminate the theory and practice of justifying public policies in contemporary democracies. They not only develop their theory of deliberative democracy in new directions but also apply it to new practical problems. They discuss bioethics, health care, truth commissions, educational policy, and decisions to declare war. In "What Deliberative Democracy Means," which opens this collection of essays, they provide the most accessible exposition of deliberative democracy to date. They show how deliberative democracy should play an important role even in the debates about military intervention abroad.Why Deliberative Democracy? contributes to our understanding of how democratic citizens and their representatives can make justifiable decisions for their society in the face of the fundamental disagreements that are inevitable in diverse societies. Gutmann and Thompson provide a balanced and fair-minded approach that will benefit anyone intent on giving reason and reciprocity a more prominent place in politics than power and special interests.

While Roman Ingarden is well known for his work in aesthetics and studies in ontology, one of his most important and lasting contributions has been largely overlooked: his approach to a general ontology of social and cultural objects. Ingarden himself discusses cultural objects other than works of art directly in the first section of “The Architectural Work”1, where he develops a particularly penetrating view of the ontology of buildings, flags, and churches. This text provides the core insight into how his (...) more lengthy studies of the ontology of works of art in The Literary Work of Art and the rest of The Ontology of the Work of Art, combined with the ontological distinctions of Der Streit um die Existenz der Welt, may be used to understand social and cultural objects. The view that results, I will argue, is based in foreseeing problems with the reductivist and projectivist views that remain popular, and is capable of resolving central problems still thought to plague those who would offer a theory of cultural objects.

Arguments that ordinary inanimate objects such as tables and chairs, sticks and stones, simply do not exist have become increasingly common and increasingly prominent. Some are based on demands for parsimony or for a non-arbitrary answer to the special composition question; others arise from prohibitions against causal redundancy, ontological vagueness, or co-location; and others still come from worries that a common sense ontology would be a rival to a scientific one. Until now, little has been done to address these arguments (...) in a unified and systematic way. Ordinary Objects is designed to fill this gap, demonstrating that the mistakes behind all of these superficially diverse eliminativist arguments may be traced to a common source. It aims to develop an ontology of ordinary objects subject to no such problems, providing perhaps the first sustained defense of a common sense ontology in two generations. The work done along the way addresses a number of major issues in philosophy of language and metaphysics, contributing to debates about analyticity, identity conditions, co-location and the grounding problem, vagueness, overdetermination, parsimony, and ontological commitment. In the end, the most important result of addressing these eliminativist arguments is not merely avoiding their conclusions; examining their failings also gives us reason to suspect that many apparent disputes in ontology are pseudo-debates. For it brings into question widely-held assumptions about which uses of metaphysical principles are appropriate, which metaphysical demands are answerable, and how we should go about addressing such fundamental questions as "What exists?". As a result, the work of Ordinary Objects promises to provide not only the route to a reflective understanding of our unreflective common-sense view, but also a better understanding of the proper methods and limits of metaphysics.

I offer a new interpretation of Heidegger’s analysis of anxiety in Being and Time as an account of the relationship between individual agents and the public normative practices of their communities. According to a prominent recent interpretation, Heidegger’s discussions of anxiety, death and the “call of conscience” together explain how we can respond to the norms of our practices as reasons and subject them to critical reflection. I argue that this is only part of the story. Anxiety is an occasion (...) for Dasein to take responsibility for its ongoing activity of interpreting the possibilities for living and acting made available by the normative practices of its community, which is presupposed and overlooked from the perspective of everyday Dasein. Public normativity underdetermines Dasein’s conception of what it would mean to take up any of the possibilities available in its world as a way of living its own life. (shrink)

This book showcases the best in modern medieval and religious scholarship, deploying spirited and progressive approaches to the study of Christian mysticism and the philosophy of religion. The volume explores excessive forms of desire and eroticism at play within Christian mystical texts and the historiographical, theological, and philosophical problems bound up in the interrogation of extraordinary experiences of the divine. Amy Hollywood examines how feminist and queer studies have changed the history of mysticism and how the study of religion in (...) general has altered our understanding of what is true, what is real, and what it means to research a historical subject. Ideal for novices and experienced scholars alike, this volume models cutting-edge methods for the ethical study of divine embodiment and religious experience in the Middle Ages. It makes a forceful case for thinking about religion as both belief and practice, in which traditions marked by change are passed down through generations, laying the groundwork for their own critique. Through a provocative integration of medieval sources and texts by Derrida, Butler, Asad, and Chakrabarty this book redefines what it means to engage critically with history and those embedded within it.

An incisive examination of bioethics and American healthcare, and their profound affects on American culture over the last sixty years, from two eminent scholars. An eye-opening look at the inevitable moral choices that come along with tremendous medical progress, Everybody Wants to Go to Heaven but Nobody Wants to Die is a primer for all Americans to talk more honestly about health care. Beginning in the 1950s when doctors still paid house calls but regularly withheld the truth from their patients, (...) Amy Gutmann and Jonathan D. Moreno explore an unprecedented revolution in health care and explain the problem with America’s wanting everything that medical science has to offer without debating its merits and its limits. The result: Americans today pay far more for health care while having among the lowest life expectancies and highest infant mortality of any affluent nation. Gutmann and Moreno—“incisive, influential, and pragmatic thinkers” (Arthur Caplan)—demonstrate that the stakes have never been higher for prolonging and improving life. From health care reform and death-with-dignity to child vaccinations and gene editing, they explain how bioethics came to dominate the national spotlight, leading and responding to a revolution in doctor-patient relations, a burgeoning world of organ transplants, and new reproductive technologies that benefit millions but create a host of legal and ethical challenges. With striking examples, the authors show how breakthroughs in cancer research, infectious disease, and drug development provide Americans with exciting new alternatives, yet often painful choices. They address head-on the most fundamental challenges in American health care: Why do we pay so much for health care while still lacking universal coverage? How can medical studies adequately protect individuals who volunteer for them? What’s fair when it comes to allocating organs for transplants in truly life-and-death situations? A lucid and provocative blend of history and public policy, this urgent work exposes the American paradox of wanting to have it all without paying the price. (shrink)

Imagination is celebrated as our vehicle for escape from the mundane here and now. It transports us to distant lands of magic and make-believe, and provides us with diversions during boring meetings or long bus rides. Yet the focus on imagination as a means of escape from the real world minimizes the fact that imagination seems also to furnish us with knowledge about it. Imagination seems an essential component in our endeavor to learn about the world in which we live--whether (...) we're planning for the future, aiming to understand other people, or figuring out whether two puzzle pieces fit together. But how can the same mental power that allows us to escape the world as it currently is also inform us about the world as it currently is? Ten original essays grapple with this neglected question; in doing so, they present a diverse array of positions ranging from cautious optimism to deep-seated pessimism. Blending perspectives from philosophy of mind, cognitive science, epistemology, aesthetics, and ethics, Knowledge Through Imagination sheds new light on the epistemic role of imagination. (shrink)

In recent analytic metaphysics, the view that ‘ordinary inanimate objects such as sticks and stones, tables and chairs, simply do not exist’ has been defended by some noteworthy writers. Thomasson opposes such revisionary ontology in favour of an ontology that is conservative with respect to common sense. The book is written in a straightforward, methodical and down-to-earth style. It is also relatively non-specialized, enabling the author and her readers to approach problems that are often dealt with in isolation in a (...) more unified way.Thomasson's arguments are mainly counter-attacks on six ‘eliminativist’ arguments against ordinary objects. A causal redundancy argument espoused by Trenton Merricks holds that to suppose that there are ordinary objects is to suppose that these objects have distinctive causal powers. However, the casual efficacy of a baseball, for example, is exhausted by that of some suitably arranged …. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.1 (2001) 23-47 [Access article in PDF] Suárez' Doctrine of Eternal Truths Amy D. Karofsky 1. Introduction The primary aim of this paper is to offer an interpretation of Suárez' doctrine of eternal truths as found in Metaphysical Disputation XXXI, chapter XII, sections 38-47. There, following the typical scholastic style, Suárez considers and rejects several theories before developing his own. Because it is (...) somewhat difficult to determine what view Suárez ultimately adopts, interpretations of this passage tend to vary. For example, Norman Wells suggests that the necessity and eternality of essential propositions is grounded in the intellect of the divine being. 1 Armand Maurer and John P. Doyle maintain that eternal truths are not grounded in the being of God, but rather in the real being of the essences themselves. 2 I will argue that none of these interpretations adequately expresses Suárez' project, for Suárez wants a solution to the problem of eternal truths that does not depend upon the will of the divine being and one that avoids any ontological commitment to unactualized, possible essences. 3 2. Explanation of the Problem of Eternal Truths Suárez begins the thirty-first disputation with a proof of the identity of essence and existence in finite creatures. The key premise in his argument is the claim that, lacking existence, an unactualized essence is not a being, but absolutely [End Page 23] nothing. 4 By 'being' Suárez means existing being, or a being that is created by God. 5 Unlike the essence of God, the essence of a creature is dependent for its being on the efficient causality of God. Prior to the creative act of God, then, the essence of a creature is not an existing being, hence not a being at all; the unactualized, possible essence is a non-being or nothing.From the claim that a nonexistent essence is absolutely nothing, the following problem arises:... si, ablata existentia, perit essentia, ergo propositiones illae in quibus praedicata essentialia de re praedicantur, non sunt necessariae, neque perpetuae veritatis... 6An essential proposition of the form "X is f" is a proposition in which an essential property f is attributed to an object X. If there are no X's in existence, then there is nothing of which f can be predicated. It would seem, then, that the proposition, "X is f" must be false. One might maintain, however, that even though there are no X's in existence, there is an essence (of) X that has the property f. And in this way, "X is f" remains true, even if there are no X's in existence.However, if one holds, as Suárez does, that the unactualized essence is absolutely nothing, then this solution will not work. For if there are no X's in existence, and if a nonexistent essence is absolutely nothing, then there is nothing of which the essential attribute can be predicated. Thus it appears that any proposition that purports to attribute a property to a nonexistent object must be false and so clearly it can be neither necessarily nor eternally true. Therefore, because Suárez believes that an unactualized essence is absolutely nothing, he seems to be committed to the claim that essential propositions are neither necessarily, nor eternally, true. I will refer to this problem as the Problem of Eternal Truths.Another way to illustrate the Problem of Eternal Truths is to see that there are two seemingly inconsistent propositions: AN: An unactualized, possible essence is absolutely nothing, and NE: True essential propositions are necessarily and eternally true. [End Page 24]Given that a proposition in which a property is attributed to an unactualized essence is false, if Suárez wants to assert the truth of AN, it would appear that he must deny the truth of NE, and, in so doing, reject the possibility of any science of creatures that deals only with necessary truths.Suárez considers three different solutions to this problem: (What I will call) the Aristotelian Solution, the Divine...

Creations of the Mind: Essays on Artifacts and their Representation, ed. Stephen Laurence and Eric Margolis, Oxford: Oxford University Press, 2007.

Existence questions have been topics for heated debates in metaphysics, but this book argues that they can often be answered easily, by trivial inferences from uncontroversial premises. This 'easy' approach to ontology leads to realism about disputed entities, and to the view that metaphysical disputes about existence questions are misguided.

Humans have the ability to learn surprisingly complicated statistical information in a variety of modalities and situations, often based on relatively little input. These statistical learning (SL) skills appear to underlie many kinds of learning, but despite their ubiquity, we still do not fully understand precisely what SL is and what individual differences on SL tasks reflect. Here, we present experimental work suggesting that at least some individual differences arise from stimulus-specific variation in perceptual fluency: the ability to rapidly or (...) efficiently code and remember the stimuli that SL occurs over. Experiment 1 demonstrates that participants show improved SL when the stimuli are simple and familiar; Experiment 2 shows that this improvement is not evident for simple but unfamiliar stimuli; and Experiment 3 shows that for the same stimuli (Chinese characters), SL is higher for people who are familiar with them (Chinese speakers) than those who are not (English speakers matched on age and education level). Overall, our findings indicate that performance on a standard SL task varies substantially within the same (visual) modality as a function of whether the stimuli involved are familiar or not, independent of stimulus complexity. Moreover, test–retest correlations of performance in an SL task using stimuli of the same level of familiarity (but distinct items) are stronger than correlations across the same task with stimuli of different levels of familiarity. Finally, we demonstrate that SL performance is predicted by an independent measure of stimulus-specific perceptual fluency that contains no SL component at all. Our results suggest that a key component of SL performance may be related to stimulus-specific processing and familiarity. (shrink)

Cognitive Science, Volume 46, Issue 2, February 2022.

This challenging study places fiction squarely at the centre of the discussion of metaphysics. Philosophers have traditionally treated fiction as involving a set of narrow problems in logic or the philosophy of language. By contrast Amie Thomasson argues that fiction has far-reaching implications for central problems of metaphysics. The book develops an 'artifactual' theory of fiction, whereby fictional characters are abstract artifacts as ordinary as laws or symphonies or works of literature. By understanding fictional characters we come to understand how (...) other cultural and social objects are established on the basis of the independent physical world and the mental states of human beings.
