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.

A model of writing in cognitive development, Understanding the Representational Mind synthesizes the burgeoning literature on the child’s theory of mind to provide an integrated account of children’s understanding of representational and mental processes, which is crucial in their acquisition of our commonsense psychology. Perner describes experimental work on children’s acquisition of a theory of mind and representation, offers a theoretical account of this acquisition, and gives examples of how the increased sophistication in children’s theory of mind improves their understanding (...) of social interaction and how, in the case of autistic children, an impairment results in social ineptitude. He analyzes the concepts of representation and metarepresentation as they appear in current discussion in the philosophy of cognitive science and explains how the unfolding of mental representation enables infants to comprehend change over time, engage in pretence, and use representational systems like pictures and language. Perner goes on to show that around age four children become able to understand the representational nature of pictures and language and to distinguish appearance from reality. Introducing basic distinctions in philosophy of mind for characterizing the mental, Perner discusses differences in how commonsense and cognitive psychology view the mind. Tracing the onset of a commonsense psychology in the social and emotional awareness of early infancy, he reveals how the child begins to take a cognitive, representational view of the mind with repercussions for children’s episodic memory, self control, and their ability to engage in deception. Perner concludes by describing the observed developmental changes as a case of theory change And contrasts his thesis with competing proposals. Josef Perner is Lecturer in Experimental Psychology at Sussex University, Brighton, England. (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)

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)

Wenn wir handeln, greifen wir in den Lauf der Welt ein und führen Veränderungen herbei, von denen wir zu Recht denken, daß sie nicht eingetreten wären, hätten wir nicht eingegriffen. Durch menschliche Eingriffe herbeigeführte Veränderungen machen aber nur einen kleinen Teil dessen aus, was in der Welt geschieht. Der größere Teil geschieht ohne unser Zutun. Beide Arten von Geschehnissen werden sowohl alltagssprachlich wie philosophisch in kausalem Vokabular beschrieben. Handelnde werden als kausale Urheber eines Geschehens verstanden; zugleich sind die mit Handlungen (...) einhergehenden Körperbewegungen kausal in natürliche Verläufe eingebettet: sie haben Ursachen und Wirkungen. -/- Die Studie versteht sich als Beitrag zu einer deskriptiven Metaphysik des Kausal- und des Handlungsbegriffes anhand einer Gegenüberstellung von kausaler Handlungstheorie und Handlungstheorie der Kausalität. Der Neuansatz besteht darin, das Verhältnis von Kausalitäts- und Handlungsbegriff konsequent als eine Gleichung mit zwei Unbekannten zu behandeln. -/- Die Untersuchung besteht aus drei Teilen. Der erste Teil dient einer Darstellung und Kritik der kausalen Handlungstheorie, welche den Kausalbegriff zur Analyse des Handlungsbegriffs verwendet. Ihr zufolge sind Handlungen Körperbewegungen, die sich durch eine besondere kausale Genese auszeichnen. Es zeigt sich, daß eine sachgerechte Lösung der internen Probleme dieser Theorie schlecht mit dem weithin akzeptierten Prinzip vom nomologischen Charakter der Kausalität vereinbar ist. Die Auseinandersetzung mit diesem Prinzip steht im Zentrum des zweiten, kausalitätstheoretischen Teils des Buches. Nancy Cartwright vertritt die These, daß es die strikten empirischen Sukzessionsgesetze, die die nomologische Kausalitätsauffassung erfordert, nicht gibt. Diese These wird ausführlich gegen Einwände aus der Wissenschaftstheorie verteidigt. Es entsteht ein kausalitätstheoretisches Vakuum, dessen Auffüllung der dritte Teil dient. Hier wird der kausalen Handlungstheorie eine Theorie der Kausalität gegenübergestellt, die das Explikationsverhältnis von „handeln“ und „verursachen“ umkehrt: die interventionistische Theorie der Kausalität, derzufolge der gewöhnliche Kausalitätsbegriff nicht erläutert werden kann, ohne den Begriff des absichtlichen Eingreifens in natürliche Verläufe ins Spiel zu bringen. Vorliegende Versionen dieser Theorie sind allerdings von schwerwiegenden Einwänden betroffen (Zirkularität, Anthropomorphismus). Um sie zu entkräften, muß die interventionistische Theorie in der richtigen Weise mit der kontrafaktischen Theorie der Kausalität kombiniert werden. Nur so läßt sich ein begrifflicher Rahmen aufspannen, in dem die durch menschliches Zutun und die ohne menschliches Zutun geschehenden Veränderungen in der Körperwelt gleichermaßen Platz finden, ohne daß neben der gewöhnlichen Ereigniskausalität eine zweite Art von Verursachung („Akteurskausalität“, „Kausalität aus Freiheit“) angenommen werden muß.

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)

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)

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.

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)

"Amongst the human mind's proudest accomplishments is the invention of a science dedicated to understanding itself: cognitive science. ... This volume is an authoritative guide to this exhilarating new body of knowledge, written by the experts, edited with skill and good judment. If we were to leave a time capsule for the next millennium with records of the great achievements of civilization, this volume would have to be in it."--Steven Pinker.

Critical discussion of Jerry Fodor's Concepts: Where Cognitive Science Went Wrong (1998).

Survey article which introduces a collection of essays on philosophical naturalism, mainly dealing with the question what “naturalism” means in contemporary philosophy. Structure of the article: 1. History of Ideas/History of the Problems, 2. Man as a Part of Nature, 3. The Explanatory Primacy of the Natural Sciences, 4. Naturalism and Unity of Science, 5. The Consideration of Empirical Knowledge, 6. Naturalism, Science and Common Sense.

Naturalism in theoretical philosophy comes in three kinds: metaphysical, scientific and semantical. Metaphysical naturalism holds that only natural things exist, scientific (or methodological) naturalism holds that the methods of natural science provide the only avenue to truth, semantic (or analytic) naturalism tries to provide sufficient nonintentional conditions for intentional phenomena. The paper argues that analytic naturalism does not render metaphysical or scientific naturalism obsolete, but can be understood as a further step in elaborating upon these programmes. The intentional idiom of (...) belief-desire psychology is the main obstacle for a scientific view of the world. It is hard to see how human beings and their abilities could get integrated into the natural order if intentional phenomena defy analysis in naturalistically acceptable terms. Against this view, Stephen Stich has argued that the search for a naturalistic criterion of acceptable predicates is misguided, since there is no way of identifying naturalistically acceptable predicates in advance. All that counts, Stich claims, is that the predicates in question are applied in “successful scientific theories”. A naturalist, however, must be able to indicate what he takes to be successful science and why. Perhaps analytic naturalism is without prospect of success. This would be bad news for the naturalist, which he cannot sidestep by claiming hat scientific naturalism must have had something different in mind. (shrink)

In a number of articles, Hans-Johann Glock has argued against the »lingualist« view that higher mental capacities are a prerogative of language-users. He has defended the »assimilationist« claim that the mental capacities of humans and of non-human animals differ only in degree. In the paper under discussion, Glock argues that animals are capable of acting for reasons, provided that reasons are construed along the lines of the new »objectivist« theory of practical reasons.

Transactive memory theory describes the processes by which benefits for memory can occur when remembering is shared in dyads or groups. In contrast, cognitive psychology experiments demonstrate that social influences on memory disrupt and inhibit individual recall. However, most research in cognitive psychology has focused on groups of strangers recalling relatively meaningless stimuli. In the current study, we examined social influences on memory in groups with a shared history, who were recalling a range of stimuli, from word lists to personal, (...) shared memories. We focused in detail on the products and processes of remembering during in-depth interviews with 12 older married couples. These interviews consisted of three recall tasks: (1) word list recall; (2) personal list recall, where stimuli were relevant to the couples’ shared past; and (3) an open-ended autobiographical interview. We conducted these tasks individually and then collaboratively two weeks later. Across each of the tasks, although some couples demonstrated collaborative inhibition, others demonstrated collaborative facilitation. We identified a number of factors that predicted collaborative success, in particular, group-level strategy use. Our results show that collaboration may help or hinder memory, and certain interactions are more likely to produce collaborative benefits. (shrink)

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.

For example, definitions of ‘subthreshold disorders’ and of the ‘prodromal stages’ of diseases are notoriously contentious.

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?

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.

Ein Homunkulus im philosophischen Sprachgebrauch ist eine postulierte menschenähnliche Instanz, die ausdrücklich oder unausdrücklich zur Erklärung der Arbeitsweise des menschlichen Geistes herangezogen wird. Als Homunkulus-Fehlschluß wird die Praxis bezeichnet, Prädikate, die auf kognitive oder perzeptive Leistungen einer ganzen Person zutreffen, auch auf Teile von Personen oder auf subpersonale Vorgänge anzuwenden, was typischerweise zu einem Regreß führt. Der vorliegende Beitrag erörtert den Homunkulus-Fehlschluß zunächst in argumentationstheoretischer Hinsicht und stellt dabei ein Diagnoseschema auf. Dann werden zwei Anwendungsfelder erörtert: Instanzenmodelle der Psyche (Platon, (...) Freud) sind ihrer Natur nach homunkulusgefährdet, denn es ist aufgrund der holistischen Zuschreibungsbedingungen mentaler Fähigkeiten schwer plausibel zu machen, wie eine innerpsychische Instanz den ihr zugedachten Beitrag leisten soll, ohne über eine eigene Psyche zu verfügen. Der zweite Anwendungsfall ist das Problem des invertierten Netzhautbildes in der Philosophie der Wahrnehmung, das wissenschafts- und philosophiegeschichtlich eingebettet und unter besonderer Berücksichtigung von Descartes diskutiert wird. Schließlich werden offensive Rechtfertigungen homunkularer Redeweisen erörtert und größtenteils zurückgewiesen. (shrink)

The ability to evaluate the quality of explanations is an essential part of children’s intellectual growth. Explanations can be faulty in structural ways such as when they are circular. A circular explanation reiterates the question as if it were an explanation rather than providing any new information. Two experiments (N = 77) examined children’s preferences when faced with circular and noncircular explanations. The results demonstrate that a preference for noncircular explanations is present, albeit in a fragile form, by 5 or (...) 6 years of age and that it appears robustly by 10 years of age. Thus, the ability to evaluate the quality of explanations based on structural grounds appears to develop rapidly during the elementary school years. Ó 2007 Elsevier Inc. All rights reserved.

This collection is drawn from a recent Global Political conference held to mark the centenary of the birth of Harold Innis, Canada's most important political economist. Throughout his life, Innis was concerned with topics which remain central to political ecology today, such as the link between culture and nature, the impact of humanity on the environment and the role of technology and communications. In this volume, the contributors address environmental issues which Innes was concerened with, from a contemporary, political economy (...) perspective. They explore a wide range of themes and issues including: sustainability; risk and regulation; population growth; and planetary management. Case studies provide further insight into issues such as industrial racism, women and development and collective action. (shrink)

Der Topos von der Unerschöpflichkeit des Gegenstands wird mit der Phänomenologie assoziiert. Den ihm verwandten Topos von der Unaussprechlichkeit des Individuellen haben Goethe und die deutschen Romantiker in die Welt getragen. Der Diktion der analytischen Philosophie sind die Ausdrücke „unerschöpflich“ und „unaussprechlich“ fremd. Dieser Umstand sollte analytische Philosophen nicht davon abhalten, sich den sprachphilosophischen und ontologischen Problemen zuzuwenden, die sich hinter den besagten Formeln verbergen. Husserls Wort für Unerschöpflichkeit ist „Fülle“. Die „Fülle des Gegenstandes“ erläutert Husserl als den „Inbegriff der (...) ihn konstituierenden Bestimmtheiten“, seine „individualisierenden Bestimmtheiten“ eingeschlossen. Ich werde in diesem Aufsatz von deskriptiver Unerschöpflichkeit sprechen, die ich auf eine ontische Eigenart der konkreten Einzeldinge zurückführe. Den Begriff der deskriptiven Unerschöpflichkeit werde ich zunächst anhand des Problems entwickeln, die Eigenschaften eines Einzeldings zu zählen. Aristoteles, Leibniz und Kant beantworten die Frage, wie viele Eigenschaften ein Einzelding hat, gleichlautend: es sind potentiell unendlich viele (1.). Die ontologische Kategorie, für die dies gilt, ist die der konkreten, raumzeitlichen Einzeldinge (2.). Unter (3.) wird der Befund der deskriptiven Unerschöpflichkeit näher erläutert und ausdifferenziert. Unter (4.) wird ein sprachphilosophisch motivierter Einwand gegen die Unerschöpflichkeitsthese diskutiert und zurückgewiesen: der Einwand aus der endlichen Zahl der Prädikate. Dann werde ich die Begriffe Leerstelle, Auflösung und ontische Dichte einführen, um meinen Befund zu sichern und zu präzisieren (5.). Unter dem Stichwort „Unerschöpflich oder bloß faktisch unerschöpft?“ diskutiere ich die Frage, worin das prinzipielle Hindernis für das Unternehmen liegen soll, ein Einzelding erschöpfend zu beschreiben (6.). Anschließend kontrastiere ich die Unerschöpflichkeitsthese mit der pathetischen Formel von der „Unaussprechlichkeit des Individuellen“, um zu verdeutlichen, was mit ersterer nicht gemeint ist (7.). Diese Diskussion führt zu ontologischen Überlegungen über Individualität, Einzigkeit und haecceitas (8.). Schließlich bringe ich den Gedanken ins Spiel, daß wir in der natürlichen Sprache beliebig feine semantische Unterscheidungen treffen können, der auf den ersten Blick in einer gewissen Spannung zur These der deskriptiven Unerschöpflichkeit steht. Diese Spannung werde ich unter (9.) und (10.) zu mildern suchen und dabei meinen Begriff der ontischen Dichte zu Goodmans Begriff der semantischen Dichte in Beziehung setzen. (shrink)
