In Concepts, Kinds, and Cognitive Development, Frank C. Keil provides a coherent account of how concepts and word meanings develop in children, adding to our understanding of the representational nature of concepts and word meanings at all ages. Keil argues that it is impossible to adequately understand the nature of conceptual representation without also considering the issue of learning. Weaving together issues in cognitive development, philosophy, and cognitive psychology, he reconciles numerous theories, backed by empirical evidence from nominal (...) kinds studies, natural-kinds studies, and studies of fundamental categorical distinctions. He shows that all this evidence, when put together, leads to a better understanding of semantic and conceptual development. The book opens with an analysis of the problems of modeling qualitative changes in conceptual development, investigating how concepts of natural kinds, nominal kinds, and artifacts evolve. The studies on nominal kinds document a powerful and unambiguous developmental pattern indicating a shift from a reliance on global tabulations of characteristic features to what appears to be a small set of defining ones. The studies on natural kinds document an analogous shift toward a core theory instead of simple definition. Both sets of studies are strongly supported by cross cultural data. While these patterns seem to suggest that the young child organizes concepts according to characteristic features, Keil argues that there is a framework of conceptual categories and causal beliefs that enables even very young children to understand kinds at a deeper, theoretically guided, level. This account suggests a new way of understanding qualitative change and carries strong implications for how concepts are represented at any point in development. A Bradford Book. (shrink)

At the most general level I am interested in how we come to make sense of the world around us. Much of this research involves asking how intuitive explanations and understandings emerge in development and how they are related to notions of cause, mechanism and agency. These relations are linked to broader questions of what concepts are, how they change with development and increasing expertise and how they are structured in adults.

The article discusses Schürmann’s essay “‘What Must I Do?’ at the End of Metaphysics” (1983). Although acknowledging the importance of the ethical question (“What must I do?”) and the need for ethical orientation, Schürmann here connects his ethical project to an account of the history of metaphysics in a way that rules out any positive answer to the ethical question. Schürmann rather envisages what I call a transformative ethics, a basic modification of our ways of thinking and acting. Key to (...) this project is the recognition that normative claims are of an intrinsically contradictory nature, leading to what I call his liquid normativity view. I then contrast two ways of understanding the link between ethics and the history of being: the sequential or revolutionary and the phenomenological model. While Schürmann opts for the first, I argue that the latter is preferable. (shrink)

The Special Focus on invitation policy at universities contains a target article by Romy Jaster and Geert Keil, five commentaries, and a response. The question under discussion is what disqualifies a person from being invited to speak at a university. On liberal, Millian approaches, the epistemic benefits of free speech preclude no-platforming policies. More restrictive approaches demand the exclusion of speakers who are considered racist or otherwise hostile against marginalized groups. Jaster and Keil take a virtue-based approach to (...) invitation policy: A person is ineligible as a speaker if she exhibits specific intellectual vices that are detrimental to the pursuit of truth, the university’s raison d’être. The five critics raise various concerns. Birgit Recki deems the virtue-based approach too restrictive: It is prone to exclude some speakers who make intellectually stimulating contributions. Eva von Redecker and Daniel Loick deem the criterion too permissive: It allows for contributions that should have no place on campus. Dieter Schönecker and Maria-Sibylla Lotter object that the approach is silent on all recent actual cases of ‘cancelling’ at universities. In their response, Jaster and Keil address these concerns and clarify their position. (shrink)

The article sketches two accounts of failure. On a broadly Aristotelian view, failure is conceived as the privation of success; on a view I call existential failure, failure and the capacity to begin anew are seen as explanatorily more basic than success. I distinguish three types of existential failure with regard to (i) individual existence, (ii) a cultural system, (iii) humanity as a whole. While the senses in which agents fail are different on each case, an underlying feature of failing (...) in its different instances is its indirect affirmation of human freedom. To be free is to be capable of failure. I conclude by contrasting these two accounts with the scenario of human extinction. Is it a failure if our species ceases to exist? Drawing on Hans Jonas, I argue that here the contrast between excess and failure returns in a different form. (shrink)

In psychiatry there is no sharp boundary between the normal and the pathological. Although clear cases abound, it is often indeterminate whether a particular condition does or does not qualify as a mental disorder. For example, definitions of ‘subthreshold disorders’ and of the ‘prodromal stages’ of diseases are notoriously contentious. -/- Philosophers and linguists call concepts that lack sharp boundaries, and thus admit of borderline cases, ‘vague’. Although blurred boundaries between the normal and the pathological are a recurrent theme in (...) many publications concerned with the classification of mental disorders, systematic approaches that take into account philosophical reflections on vagueness are rare. This book provides interdisciplinary discussions about vagueness in psychiatry by bringing together scholars from psychiatry, psychology, philosophy, history, and law. It draws together various lines of inquiry into the nature of gradations between mental health and disease and discusses the individual and societal consequences of dealing with blurred boundaries in medical practice, forensic psychiatry, and beyond. -/- Part I starts with an overview chapter that helps readers to navigate through the philosophy of vagueness and through the various debates surrounding demarcation problems in the classification and diagnosis of mental illness. Part II encompasses historical and recent philosophical positions on gradualist approaches to health and disease. Part III approaches the vagueness of present psychiatric classification systems, and the debates concerning their revisions by scrutinizing controversial categories, such as posttraumatic stress disorder, and the difficulties of day-to-day diagnostic and therapeutic practice. Part IV finally focuses on social, moral, and legal implications that arise when being mentally ill is a matter of degree. (shrink)

Two studies with 3-, 4-, and 5-year-olds (N 104) examined whether young children can differentiate expertise in the minds of others. Study 1 revealed that all children in the sample could correctly attribute observable knowledge to familiar experts (i.e., a doctor and a car mechanic). Further, 4- and 5-year-olds could correctly attribute knowledge of underlying scientific principles to the appropriate experts. In contrast, Study 2 demonstrated that 3-, 4-, and 5-year-olds have difficulty making attributions of knowledge of scientific principles to (...) unfamiliar experts. A computational analysis in Study 3 indicated that 4- and 5-year-olds’ successes on the first two studies could not be attributed to the way in which words co-occur in discourse. Overall, these studies showed that young children have a sense of the division of cognitive labor, albeit fragile. (shrink)

In view of the failures made in the past, the necessity of a reform of the old-age pension scheme is pointed out and biblically proved. The new positions of women and men demand ·the organization of an independent social protection of the housewife and mother, the decrease in births the further development of the two-generations-contract to a three-generations-contract. The commonly agreed old-age pension ·reform of 1992 is measured against these elaborated exigencies and criticized in crucial points at issue.

The rise of appeals to intuitive theories in many areas of cognitive science must cope with a powerful fact. People understand the workings of the world around them in far less detail than they think. This illusion of knowledge depth has been uncovered in a series of recent studies and is caused by several distinctive properties of explanatory understanding not found in other forms of knowledge. Other experimental work has shown that people do have skeletal frameworks of expectations that constrain (...) richer ad hoc theory construction on the fly. These frameworks are supplemented by an ability to evaluate and rely on the division of cognitive labour in one's culture, an ability shown to be present even in young children. (shrink)

Vague expressions are omnipresent in natural language. Their use in legal texts is inevitable. A law phrased in vague terms will often leave it indeterminate whether it applies to a particular case. This places the law at odds with legal values. One of the fundamental pillars of the rule of law is legal certainty. The determinacy of the law enables people to use it as a guide and allows judges make impartial decisions. Vagueness poses a threat to these ideals. In (...) borderline cases, the law seems to be indeterminate and thus incapable of serving its core rule of law value. -/- In the philosophy of language, vagueness has become one of the hottest topics of the past two decades. Linguists and philosophers have investigated what distinguishes ‘soritical’ vagueness from other kinds of linguistic indeterminacy, such as ambiguity, generality, open texture, and family resemblance concepts. There is a vast literature that discusses the logical, semantic, pragmatic, and epistemic aspects of these phenomena. Legal theory has hitherto paid little attention to the differences between the various kinds of linguistic indeterminacy that are grouped under the heading of ‘vagueness’, let alone to the various theories that try to account for these phenomena. -/- Bringing together leading scholars working on the topic of vagueness in philosophy and in law, this book fosters a dialogue between philosophers and legal scholars by examining how philosophers conceive legal ambiguity from their theoretical perspective and how legal theorists make use of philosophical theories of vagueness. -/- The chapters of the book are organized into three parts. The first part addresses the import of different theories of vagueness for the law, referring to a wide range of theories from supervaluationist to contextualist and semantic realist accounts in order to address the question of whether the law can learn from engaging with philosophical discussions of vagueness. The second part of the book examines different vagueness phenomena. The contributions suggest that paying greater attention to these phenomena can make lawyers aware of specific issues and solutions as yet overlooked. The third part deals with the pragmatic aspects of vagueness in law and with the professional, political, and moral issues to which such vagueness gives rise. (shrink)

If folk science means individuals having well worked out mechanistic theories of the workings of the world, then it is not feasible. Laypeople’s explanatory understandings are remarkably coarse, full of gaps, and often full of inconsistencies. Even worse, most people overestimate their own understandings. Yet recent views suggest that formal scientists may not be so different. In spite of these limitations, science somehow works and its success offers hope for the feasibility of folk science as well. The success of science (...) arises from the ways in which scientists learn to leverage understandings in other minds and to outsource explanatory work through sophisticated methods of deference and simplification of complex systems. Three studies ask whether analogous processes might be present not only in laypeople but also in young children and thereby form a foundation for supplementing explanatory understandings almost from the start of our first attempts to make sense of the world.

The division of cognitive labor is fundamental to all cultures. Adults have a strong sense of how knowledge is clustered in the world around them and use that sense to access additional information, defer to relevant experts, and ground their own incomplete understandings. One prominent way of clustering knowledge is by disciplines similar to those that comprise the natural and social sciences. Seven studies explored an emerging sense of these discipline‐based ways of clustering of knowledge. Even 5‐year‐olds could cluster knowledge (...) in a manner roughly corresponding to the departments of natural and social sciences in a university, doing so without any explicit awareness of those academic disciplines. But this awareness is fragile early on and competes with other ways of clustering knowledge. Over the next few years, children come to see discipline‐based clusters as having a privileged status, one that may be linked to increasingly sophisticated assumptions about essences for natural kinds. Possible mechanisms for this developmental shift are examined. (shrink)

Heidegger’s later philosophy is marked by two conflicting claims about phenomenology. On the one hand, phenomenology and philosophy generally is tasked with “responding to the claim of what is to be thought” in a novel and unprecedented manner. On the other hand, Heidegger recognizes that there have been earlier attempts at thus doing justice to phenomena; in the ontological commitments of earlier thinkers, Heidegger finds accounts of the “things themselves,” each of which has different implications for what phenomenology should concern (...) itself with. Phenomenology, as Heidegger conceives it, should thus both incorporate the history of philosophy and exceed it, yet it is unclear how these ideas can be reconciled. This chapter calls this problem the “dilemma of the historicity of phenomenology” and identifies different versions of it in Heidegger’s works after 1935/6. (shrink)

Jeder Mensch irrt – ausgenommen der Papst, wenn er Glaubenssätze verkündet. So jedenfalls befand einst das erste Vatikanische Konzil. Nun waren die Kardinäle, so bemerkt Keil frech, selbst keineswegs Träger der päpstlichen Unfehlbarkeit. »Woher wussten sie dann, dass der Papst unfehlbar ist?« Niemand weiß vorher, wann und wo er sich irren wird. Viele Philosophen haben daraus geschlossen, dass Menschen nichts wissen, sondern immer nur vermuten. Das ist aber ein Irrtum, den dieser kluge und kurzweilige Essay aufklärt.

We investigate the problem of how nonnatural entities are represented by examining university students’ concepts of God, both professed theological beliefs and concepts used in comprehension of narratives. In three story processing tasks, subjects often used an anthropomorphic God concept that is inconsistent with stated theological beliefs; and drastically distorted the narratives without any awareness of doing so. By heightening subjects’ awareness of their theological beliefs, we were able to manipulate the degree of anthropomorphization. This tendency to anthropomorphize may be (...) generalizable to other agents. God (and possibly other agents) is unintentionally anthropomorphized in some contexts, perhaps as a means of representing poorly understood.. (shrink)

Philip E. Tetlock's finding that "hedgehog" experts are worse predictors than "foxes" offers fertile ground for future research. Are experts as likely to exhibit hedgehog- or fox-like tendencies in areas that call for explanatory, diagnostic, and skill-based expertise-as they did when Tetlock called on experts to make predictions? Do particular domains of expertise curtail or encourage different styles of expertise? Can we trace these different styles to childhood? Finally, can we nudge hedgehogs to be more like foxes? Current research can (...) only grope at the answers to these questions, but they are essential to gauging the health of expert political judgment. (shrink)

Das Buch verschafft einen Überblick über die neuere Willensfreiheitsdebatte, wobei es auch die Konsequenzen der Hirnforschung für das Freiheitsproblem erörtert. Ferner entwickelt der Autor eine eigene Position, die er 'fähigkeitsbasierten Libertarismus' nennt. Er widerspricht dem breiten philosophischen Konsens, dass jedenfalls eine Art von Freiheit mit einem naturwissenschaftlichen Weltbild unverträglich sei, nämlich die Fähigkeit, sich unter gegebenen Bedingungen so oder anders zu entscheiden. Im Buch wird argumentiert, dass der libertarischen Freiheitsauffassung, die wir im Alltag alle teilen, bei näherer Betrachtung keine Tatschen (...) entgegenstehen, sondern nur philosophische Doktrinen. Zwar können wir durch unser Handeln keine Naturgesetze abändern und sind auch keine ersten Beweger, aber für ein So-oder-Anderskönnen bedarf es dessen nicht. (shrink)

One of the most prominent notions in Heidegger’s thinking about art is that of the earth. This paper probes the phenomenological potential of Heidegger’s concept by turning to the work of contemporary British artist Andy Goldsworthy. Drawing from Heidegger’s theoretical writings as well as his analysis of a poem by C.F. Meyer in “The Origin of the Work of Art” and his 1936–37 seminar on Schiller, I show that Goldsworthy’s sculptural art exemplifies different phenomenal traits of the “earth.” To supplement (...) Heidegger’s discussion, both Husserl’s claim that the earth defines the “spatiality of nature” and the role of the earth in Hegel’s philosophy of nature are taken into account. (shrink)

The article discusses the place of leisure in Hans Blumenberg’s philoso- phical anthropology, focusing on “Theorie der Unbegrifflichkeit” (2007). According to Blumenberg, the tradition of philosophical anthropology unjustly reduces human rationality to the attempt of self-preservation. Not only is the actual process of anthropogenesis better described as led by a logic of prevention, not of preservation. Sedentary life, product of preventive behavior, not only secures survival but grants leisure as the condition of culture. Yet cultural practices, although an eminent product (...) of human rationality, cannot be explained by the logic of either self- preservation or prevention. Blumenberg thus argues that within philosophical anthropology, rationality can best be explained in is orientation towards happiness, an orientation encompassing not only preventive, conceptual forms of reason, but also contemplative, non-conceptual uses, such as in myth and mysticism. As the condition for articulating a self-understanding more adequate than self-preservation or prevention, leisure thus assumes a central place in determining human nature. It is in leisure that rationality is experienced as a source of happiness. (shrink)

Machery rightly points out a diverse set of phenomena associated with concepts that create challenges for many traditional views of their nature. It may be premature, however, to give up such views completely. Here I defend the possibility of hybrid models of concept structure.

The article introduces a special issue of the journal _Metaphysica_ on vagueness and ontology. The conventional view has it that all vagueness is semantic or representational. Russell, Dummett, Evans and Lewis, inter alia, have argued that the notion of “ontic” or “metaphysical” vagueness is not even intelligible. In recent years, a growing minority of philosophers have tried to make sense of the notion and have spelled it out in various ways. The article gives an overview and relates the idea of (...) ontic vagueness to the unquestioned phenomenon of fuzzy spatiotemporal boundaries and to the associated “problem of the many”. It briefly discusses the question of whether ontic vagueness can be spelled out in terms of “vague identity”, emphasizes the often neglected role of the difference between sortal and non-sortal ontologies and suggests a deflationary answer to the ill-conceived question of whether the “ultimate source” of vagueness lies either in language or in the world.

In psychiatry there is no sharp boundary between the normal and the pathological. Although clear cases abound, it is often indeterminate whether a particular condition does or does not qualify as a mental disorder. For example, definitions of ‘subthreshold disorders’ and of the ‘prodromal stages’ of diseases are notoriously contentious. Philosophers and linguists call concepts that lack sharp boundaries, and thus admit of borderline cases, ‘vague’. This overview chapter reviews current debates about demarcation in psychiatry against the backdrop of key (...) issues within the philosophical discussion of vagueness: Are there various kinds of vagueness? Is all vagueness representational? How does vagueness relate to epistemic uncertainty? What is the value of vagueness? Given the immense social, moral, and legal importance of demarcating the normal from the pathological in psychiatry, what are the pros and cons of gradualist approaches to mental disorders, that is, of construing boundaries as matters of degree?

This chapter relates the problem of demarcating the pathological from the non-pathological in psychiatry to the general problem of defining ‘disease’ in the philosophy of medicine. Section 2 revisits three prominent debates in medical nosology: naturalism versus normativism, the three dimensions of illness, sickness, and disease, and the demarcation problem. Sections 3–5 reformulate the demarcation problem in terms of semantic vagueness. ‘Disease’ exhibits vagueness of degree by drawing no sharp line in a continuum and is combinatorially vague because there are (...) several criteria for the term’s use that might fall apart. Combinatorial vagueness explains why the other two debates appear hopeless: Should we construe ‘disease’ in a naturalistic or in a normative way? Neither answer is satisfactory. How should we balance the three dimensions of pathology? We do not have to, because illness, sickness and disease (narrowly conceived) are non-competing criteria for the application of the cluster term ‘disease’. (shrink)

This paper discusses the notion of a thing in Heidegger. Its aim is to explain the systematic place of that notion in Heidegger’s thought in relation to his ontological discourse: as what is explained through different understandings of being, things allow for a simultaneous differentiation and discussion of the different epochs in the so-called history of being. Thus a henomenology of things and thingness serves as frame of reference for all explications of ‘what there is.’ If Heidegger is a realist, (...) it is not because he attributes reality to all that is, but rather because all explanations of being refer back to how things are discovered as meaningful.
