We introduce a new metric for interdisciplinarity, based on co-author publication history. A published article that has co-authors with quite different publication histories can be deemed relatively “interdisciplinary,” in that the article reflects a convergence of previous research in distinct sets of publication outlets. In recent work, we have shown that this interdisciplinarity metric can predict citations. Here, we show that the journal Cognitive Science tends to contain collaborations that are relatively high on this interdisciplinarity metric, at about the 80th (...) percentile of all journals across both social and natural sciences. Following on Goldstone and Leydesdorff, we describe how scientometric tools provide a valuable means of assessing the role of cognitive science in broader scientific work, and also as a tool to investigate teamwork and distributed cognition. We describe how data-driven metrics of this kind may facilitate this exploration without relying upon rapidly changing discipline and topic keywords associated with publications. (shrink)

The question I consider is this: -/- The Question: Can two people–who are, and realize they are, intellectually virtuous to about the same degree–both be rational in continuing knowingly to disagree after full disclosure (by each to the other of all the relevant evidence they can think of) while at the same time thinking that the other may well be rational too? -/- I distinguish two kinds of rationality–internal and external–and argue in section 1 that, whichever kind we have in (...) mind, the answer to The Question is ‘yes’ (though that positive answer is less wholehearted in the case of external rationality). Then, in section 2, I briefly make some more general remarks about when discovering a disagreement provides a defeater and when it doesn't. In the final section, I consider an important objection to the answer given in section 1 to The Question. (shrink)

This book develops a textually grounded reconstruction of Kant’s argument in the Metaphysical Deduction. The argument proceeds in three steps, developing, first, a concept of judgment on which to base the table of logical functions, next a concept of synthesis of intuition that explains the content of the categories, and finally a concept of the understanding on which the categories belong a priori to the same faculty through which we judge. -/- The investigation presented here is an argumentative reconstruction of (...) Kant’s text. The text in question is the "Guiding Thread to the Discovery of all Pure Concepts of the Understanding" in both the 1781 (A) and 1787 (B) editions of the Critique of Pure Reason (A64-83/B89-113). To illuminate Kant’s reflections in this chapter, the reconstruction also draws on passages from elsewhere in the Critique, from Kant’s writings after the Critique, as well as notes from his Nachlass and student transcriptions of lectures he held during and subsequent to writing the Critique. Four passages, in particular, are of central importance: (i) the retrospective description of the task of the Metaphysical Deduction at B159, (ii) the retrospective description of the procedure of the "Guiding Thread" at A299/B355f., (iii) the section "On the A Priori Grounds for the Possibility of Experience" in the A-edition Transcendental Deduction of the Categories (A95-110), and (iv) §§15-21 in the B-edition Transcendental Deduction (B128-148). -/- The present interpretation of the Metaphysical Deduction thus emerges from a detailed and comprehensive analysis of the "Guiding Thread" that draws on related passages from the indicated portion of Kant’s corpus and, especially, on the aforementioned four passages from the Critique. Viewing these texts together and in a specific relation to one another suggests a reading which leaves little room for doubt. This sort of textually sensitive but charitable reconstruction helps to bring out the enduring force and interest of Kant’s philosophical position. [For Dennis Schulting's review for "Kantian Review" see under "External Links" below.] -/- -- -/- Wie hier durch textnahe und argumentative Rekonstruktion erstmals gezeigt wird, entwickelt Kant in der Metaphysischen Deduktion in drei Schritten: (i) einen Begriff des Urteils, auf dem die Tafel logischer Funktionen beruht; (ii) einen Begriff der Synthesis der Anschauung, der die Inhalte der Kategorien erklärt; und (iii) einen Begriff des Verstandes, demzufolge die Kategorien a priori zu demselben Vermögen gehören, durch das wir auch urteilen. -/- Die vorliegende Untersuchung ist eine argumentative Rekonstruktion von Kants Text. Der rekonstruierte Text ist der „Leitfaden der Entdeckung aller reinen Verstandesbegriffe" auf A 64 bis 83 / B 89 bis 113 der Kritik der reinen Vernunft in ihren beiden Auflagen von 1781 (A) und 1787 (B). Zudem werden andere, für ein Verständnis der Überlegungen in diesem Kapitel erforderliche oder zumindest erhellende Textstellen aus der Kritik herangezogen; aus Schriften, die Kant nach der Kritik geschrieben hat; sowie schließlich aus Kants Nachlass-Notizen und aus Nachschriften zu seinen Vorlesungen jeweils seit der Entstehungszeit der Kritik. Von entscheidender Bedeutung sind dabei vor allem vier weitere Passagen der Kritik selbst: i) die rückblickende Beschreibung der Aufgabe der Metaphysischen Deduktion auf B 159, ii) die rückblickende Beschreibung des Vorgehens im „Leitfaden" auf A 299/B 355 f., iii) der Abschnitt „Von den Gründen a priori zur Möglichkeit der Erfahrung" auf A 95 bis 110 der Transzendentalen Deduktion der Kategorien in der ersten Auflage und schließlich iv) die §§ 15 bis 21 auf B 128 bis 148 der Transzendentalen Deduktion der Kategorien in der zweiten Auflage der Kritik. -/- Vor dem Hintergrund einer umfassenden und detaillierten Analyse des „Leitfadens", bei Hinzuziehung verwandter Stellen aus dem umgrenzten Textbestand und nicht zuletzt bei Berücksichtigung des Verhältnisses des „Leitfadens" zu den genannten vier Passagen der Kritik legt sich eine Interpretation der Metaphysischen Deduktion nahe, die sich nur schwer bestreiten lässt, sobald diese Texte einmal gemeinsam betrachtet und auf eine bestimmte Weise zueinander ins Verhältnis gesetzt werden. Dabei kann eine durchgehend wohlwollende, argumentative Rekonstruktion dazu beitragen, auch die philosophische Überzeugungskraft der Position Kants deutlich zu machen.

Ist wirklich unser ganzes Leben vorausbestimmtes, un entrinnbares Schicksal? Oder gibt es außer der mechanischen naturwissenschaftlichen Vorstellung der Welt noch eine andere Wirklichkeit, ohne daß ein unlösbarer Konflikt beider Anschauungsweisen besteht, die im Grunde jeden Menschen, den naiven wie den gelehrtesten, angehen. Der Widerspruch besteht, daß wir uns in unserem Denken und Handeln frei fühlen und damit eine Verantwortung tragen, auch wenn wir von unserem erbbedingten Charakter und von unserem Erleben beeinflußt sind, aber doch nicht unent rinnbar an diese uns (...) versklavt scheinen. Andererseits lehrt die klassische gesamte Naturwissenschaft, daß ganz wie in der klassischen Physik eine strenge, nirgends durchbrochene Kausalität uns beherrscht. Dieser Widerspruch hat mich seit meiner Jugend nie zur Ruhe kommen lassen. Das Weltbild des Arztes mußte seit dem Altertum an der Heilbestrebung des Organismus festhalten und mußte an die rettende Tat im ärztlichen Berufe glauben. Die klassische Physik schon im Altertum, aber noch weit bewußter seit der Renaissance, lehrt dogmatisch den mechanischen Ablauf allen Geschehens unter der absoluten Herrschaft des Kausal gesetzes. Immer, wenn ich mich wissenschaftlich zu äußern hatte, bin ich dem Weltbild des Arztes gefolgt, das soll gerade diese Schrift aufzeigen. Seit aber einige Physiker von der "klassischen" Physik zu einer "modernen" Physik üb- v gegangen sind, scheint zum erstenmal das fast zweieinhalb Jahrtausende währende Rätsel lösbar. (shrink)

In economics, it has often been claimed that testing choice data for violation of certain axioms-particularly if the choice data is observed under laboratory conditions-allows conclusions about the validity of certain preference axioms and the neoclassical maximization hypothesis. In this paper I argue that these conclusions are unfounded. In particular, it is unclear what exactly is tested, and the interpretation of the test results are ambiguous. Further, there are plausible reasons why the postulated choice axioms should not hold. Last, these (...) tests make implicit assumptions about beliefs that further blur the interpretations of the results. The tests therefore say little if anything about the validity of certain preference axioms or the maximization hypothesis. (shrink)

Kant’s Metaphysical Deduction of the Categories justifies their apriority, i.e. that their contents originate in the understanding itself, while the Transcendental Deduction justifies their objectivity, both in that they purport to represent objects of experience and that they do so successfully. The apriority of the categories, as explained in terms of acts of synthesis required for having sensible intuitions of objects, is justified by establishing their generic identity with logical functions of judgment, i.e. acts of judgment required for referring concepts (...) to objects. The objective purport of the categories is justified by establishing that sensible intuitions fall under them. To finally justify that the categories represent successfully, i.e. that the objects of our intuitions fall under them, it is established that the representations of space and time do, namely by showing that the features addressed in their Metaphysical Expositions, too, are to be explained in terms of acts of synthesis.

There is a long tradition of the value of using film as a pedagogical tool. Such use spans a variety of business disciplines including organizational behavior (Smith 2009), accounting (Bay & Felton 2012), business ethics (Fisher, Grant & Palmer 2015) and cultural competency (Greene, Barden, Richardson & Hall 2014). Presented here is a recently developed course, Business in Film, which engages students in deep reflection on business issues with an emphasis on ethics and values. The course is structured around a (...) weekly film (mix of dramas and documentaries), 15 weeks, 15 films covering approximately 40 years. For each film, students prepare a 2-3 page reflection paper. Student feedback has been consistently positive, with comments along the themes of a greater appreciation of the intersection between business and the human experience, bringing to life ethical considerations, and a greater appreciation of the historical context of business events.

The transfer of tasks with sometimes far-reaching implications to autonomous systems raises a number of ethical questions. In addition to fundamental questions about the moral agency of these systems, behavioral issues arise. We investigate the empirically accessible question of whether the imposition of harm by an agent is systematically judged differently when the agent is artificial and not human. The results of a laboratory experiment suggest that decision-makers can actually avoid punishment more easily by delegating to machines than by delegating (...) to other people. Our results imply that the availability of artificial agents could provide stronger incentives for decision-makers to delegate sensitive decisions. (shrink)

Kaum eine andere künstlerische Strategie prägte das Wertesystem der Kunst des 20. Jahrhunderts wie die Wiederholung. Sie lässt sich als wesentliches Moment ausmachen, neue Wahrnehmungsweisen zu ermöglichen, Kritik an Formen der Repräsentation zu üben und neuen Sinn zu produzieren. Der Band nimmt eine kritische Revision des Phänomens für die zeitgenössische Kunst vor und eröffnet anhand bildnerischer, skulpturaler, performativer, technisch-medialer wie auch kuratorischer Wiederholungen in der Kunst eine Perspektive auf die Wiederholung als Grundbegriff des Ästhetischen.

This article discusses German and European climate policy, inquiring mainly whether the ambitious goals the EU has set itself can be achieved via the instruments presently employed for the purpose and whether these instruments are efficient. In particular we discuss shortcomings of the European emission trading system, we further level criticism at energy policy measures, notably subsidization for renewable energy sources and the overlap with emissions trading. Further we argue that while 20% reduction of CO2 is feasible at a reasonable (...) cost, derived targets such as a share of 20% of renewable energy and 20% efficiency increase is expensive and not necessary. Finally, we scrutinize the latest climate-protection package proposed by Germany’s environment minister. (shrink)

Metaphern beeinflussen unser Denken, unsere alltägliche und auch wissenschaftliche Sprache. Sie lassen Ähnlichkeiten erkennen und schaffen neues Wissen. Da unsere Kultur, unser Denken und Handeln aber zunehmend von Bildern geprägt ist, muss es dann nicht auch visuelle Metaphern geben? Und welche Bedeutung misst man ihnen bei? Till Julian Huss arbeitet erstmals die historischen und systematischen Grundlagen einer Theorie der visuellen Metapher aus. Indem das Spannungsverhältnis zwischen Metapher und Begriff sowie Sprache und Bild in den Kontext einer allgemeinen Ästhetik der (...) Metapher gestellt wird, nimmt die Metapher eine Schlüsselfunktion zwischen Sprache, Anschauung und Denken ein. (shrink)

The typical rules for truth-trees for first-order logic without functions can fail to generate finite branches for formulas that have finite models–the rule set fails to have the finite tree property. In 1984 Boolos showed that a new rule set proposed by Burgess does have this property. In this paper we address a similar problem with the typical rule set for first-order logic with identity and functions, proposing a new rule set that does have the finite tree property.

The development of new effective but expensive medical treatments leads to discussions about whether and how such treatments should be funded in solidarity-based healthcare systems. Solidarity is often seen as an elusive concept; it appears to be used to refer to different sets of concerns, and its interrelations with the concept of justice are not well understood. This paper provides a conceptual analysis of the concept of solidarity as it is used in discussions on the allocation of healthcare resources and (...) the funding of expensive treatments. It contributes to the clarification of the concept of solidarity by identifying in the literature and discussing four uses of the concept: (1) assisting patients in need, (2) upholding the solidarity-based healthcare system, (3) willingness to contribute and (4) promoting equality. It distinguishes normative and descriptive uses of the concept and outlines the overlap and differences between solidarity and justice. Our analysis shows that the various uses of the concept of solidarity point to different, even conflicting, ethical stances on whether and how access to effective, expensive treatments should be provided. We conclude that the concept of solidarity has a role to play in discussions on the accessibility and funding of newly approved medical treatments. It requires, for instance, that healthcare policies promote and maintain both societal willingness to contribute to the care of others and the value of providing care to vulnerable patients through public funding.

ArgumentIn the decades following World War II, the Cowles Commission for Research in Economics came to represent new technical standards that informed most advances in economic theory. The public emergence of this community was manifest at a conference held in June 1949 titledActivity Analysis of Production and Allocation. New ideas in optimization theory, linked to linear programming, developed from the conference's papers. The authors’ history of this event situates the Cowles Commission among the institutions of postwar science in-between National Laboratories (...) and the supreme discipline of Cold War academia, mathematics. Although the conference created the conditions under which economics, as a discipline, would transform itself, the participants themselves had little concern for the intellectual battles that had defined prewar university economics departments. The authors argue that the conference signaled the birth of a new intellectual culture in economic science based on shared scientific norms and techniques un-interrogated by conflicting notions of the meaning of either science or economics.

We study logic translations from an abstract perspective, without any commitment to the structure of sentences and the nature of logical entailment, which also means that we cover both proof- theoretic and model-theoretic entailment. We show how logic translations induce notions of logical expressiveness, consistency strength and sublogic, leading to an explanation of paradoxes that have been described in the literature. Connectives and quantifiers, although not present in the definition of logic and logic translation, can be recovered by their abstract (...) properties and are preserved and reflected by translations under suitable conditions.

When Derrida translated and commented on Husserl’s manuscript The Origin of Geometry in 1962, he gave a central place to what Husserl called the Idea “in the Kantian sense”. This article reflects on the use and function of this Idea in Derrida’s reading of Husserl. It critically interrogates the relationship between the Idea in the Kantian sense and mathematical ideality, as well as the use of this Idea in the interpretation of the Thing (Ding) and the stream of experience (Erlebnisstrom). (...) In the centre of the discussion stands what Derrida calls “pure thinking”, on which he tries to ground the Idea in the Kantian sense. (shrink)

Predication is an indisputable part of our linguistic behavior. By contrast, the metaphysics of predication has been a matter of dispute ever since antiquity. According to Plato—or at least Platonism, the view that goes by Plato’s name in contemporary philosophy—the truths expressed by predications such as “Socrates is wise” are true because there is a subject of predication (e.g., Socrates), there is an abstract property or universal (e.g., wisdom), and the subject exemplifies the property.1 This view is supposed to be (...) general, applying to all predications, whether the subject of predication is a person, a planet, or a property.2 Despite the controversy surrounding the metaphysics of predication, many theistic philosophers—including the majority of contemporary analytic theists—regard Platonism as extremely attractive. At the same time, however, such philosophers are also commonly attracted to a form of traditional theism that has at its core the thesis that God is an absolutely independent.. (shrink)

The German Democratic Republic was in existence for 41 years. A single generation spent its whole professional life there – namely those born in the early 1930s who carried this state’s hopes. With Karl Mannheim’s notion of generations as a unit in the sociology of knowledge in mind, this article describes this generation’s typical experiences from the point of view of a particularly telling group: economists at the Humboldt University of Berlin. I present their socialization in Nazi Germany, their formative (...) years in the aftermath of the Second World War that led to their choice of a politically driven profession, their studies during the first years of the GDR, when Stalinism was still the dominating dogma, and their commitment to a state career when writing their dissertations and habilitations. Ready to shoulder Honecker’s regime, their daily lives as professors were characterized by continuing attempts to reform teaching and research. In 1989 the ultimate reform transpired, and it encompassed the end of the state as well as of their professional careers. This narrative historicizes, on an experiential level, a tension often noted in GDR research, that between the ideological and productive functions of knowledge in socialism, that is, between loyalty and relevance.

Recent research on agricultural innovation has outlined social networks’ role in diffusing agricultural knowledge; however, so far, it has broadly neglected the socio-spatial dimensions of innovation processes. Against this backdrop, we apply a spatially explicit translocal network perspective in order to investigate the role of migration-related translocal networks for adaptive change in a small-scale farming community in Northeast Thailand. By means of formal social network analysis we map the socio-spatial patterns of advice sharing regarding changes in sugarcane and rice farming (...) over a period of five years. We find that, in translocally connected and mobile rural communities, a substantial share of advice originates from translocal levels. Translocal advice is dominantly provided through weak and formal ties with extension agencies and shared by few highly central larger-scale farmers within sparse local networks. This draws the picture of top-down translocal innovation flows driven by extension agencies and brokered through elite farmers. A closer look on institutional context and key actors of particular changes, however, suggests the potential of migration-related translocal networks and migration experience in fostering bottom-up innovations. Migration-related innovations transfers can promote adaptive capacity also among less favorably connected actors, especially if changes are geared towards limited household resources and are compatible with social practices of small-scale farming. We conclude that a translocal network perspective is instructive for research and extension interested in leveraging more inclusive agricultural innovation. (shrink)

Resumo Palavras-chave Keywords : Children’s literature. Music. Pedagogical practice : This article’s main purpose is to present a few possibilities of work with activities that involve pieces of children’s literature and music in the perspective of Children’s Education and first years of Primary School. As theoretical support, the paper presents several studies from authors such as Brito (2003), Ponso (2008), Souza (2006), Torres and Gallicchio (2004), among others who suggest developing activities of sound exploration through audition/appreciation and improvise/ sound editing (...) from some texts and books of children’s literature. A conclusion has been reached that the proposal of activities transforming words in music enables readers to experiment different sounds to compose the soundtrack of stories. Besides, when selecting a diversified repertoire with several texts, possibilities are created to the students to tell, recount and sing varied stories, allowing, thus, the entrance of different social voices. : Literatura Infantil.

A three-valued propositional logic is presented, within which the three values are read as ?true?, ?false? and ?nonsense?. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.

This paper offers a new account of Kant`s metaphysical deduction of the categories in the Critique of Pure Reason. This is accomplished by way of a new interpretation of Kant`s notion of function and his theory of mental activity, which is presented in terms of a logic and theory of intentional reference. A detailed discussion of the definition and use of the notion of function in the “Leading Thread” leads to an interpretation of the notion of function as a complex, (...) triparted unity of intentional reference. Kant´s thesis that the unity of judgment and the unity of intuition rest on the very same function is thus explained as the thesis of the structural identity of analysis and synthesis. The presented interpretation of the notion of function and the corresponding theory of intentional reference make it possible to deduce the titles of quality, quantity, and relation of the tables of judgments and the categories, and to justify their necessity. The conception of a logic of reference to particulars then establishes the respective three moments of these titles. The title and the moments of modality finally are grounded in the cognitive constitution of finite beings. Thus Kant`s claim for completeness of the tables of judgments and the categories can be elucidated as well as justified. -- Die vorliegende Abhandlung bietet einen neuen Zugang zu Kants metaphysischer Deduktion der Kategorien in der Kritik der reinen Vernunft. Erreicht wird dieser vermittels einer Neuinterpretation von Kants Begriff der Funktion sowie seiner Theorie mentaler Aktivität, die als eine Logik und Theorie intentionalen Bezugs dargestellt wird. Eine detaillierte Untersuchung der Definition und Verwendung des Begriffs der Funktion im „Leitfaden“ führt zu einer Interpretation des Begriffs der Funktion als komplexe, dreiteilige Einheit intentionalen Bezugs. Kants These, dass die Einheit des Urteils und die Einheit der Anschauung auf derselben Funktion beruhen , wird auf diese Weise als die These der strukturellen Identität von Analysis und Synthesis verständlich gemacht. Die vorgelegte Interpretation des Funktionsbegriffs sowie die entsprechende Theorie intentionalen Bezugs ermöglichen es, die Titel der Qualität, Quantität und Relation der Urteils- und Kategorientafel herzuleiten und ihre Notwendigkeit zu rechtfertigen. Die Konzeption einer Logik des Bezugs auf Einzeldinge begründet dann die jeweils drei Momente dieser Titel. Der Titel und die Momente der Modalität schließlich haben ihren Grund in der kognitiven Verfasstheit endlicher Wesen. Auf diese Weise kann Kants Anspruch der Vollständigkeit der Urteils- und Kategorientafel sowohl verständlich gemacht als auch begründet werden. (shrink)

Professor Merrie Bergmann presents an accessible introduction to the subject of many-valued and fuzzy logic designed for use on undergraduate and graduate courses in non-classical logic. Bergmann discusses the philosophical issues that give rise to fuzzy logic - problems arising from vague language - and returns to those issues as logical systems are presented. For historical and pedagogical reasons, three-valued logical systems are presented as useful intermediate systems for studying the principles and theory behind fuzzy logic. The major (...) fuzzy logical systems - Lukasiewicz, Gödel, and product logics - are then presented as generalisations of three-valued systems that successfully address the problems of vagueness. A clear presentation of technical concepts, this book includes exercises throughout the text that pose straightforward problems, that ask students to continue proofs begun in the text, and that engage students in the comparison of logical systems.

The following paper discusses Schiller’s interpretation of the German concept of Bildung. Bildung appears to be a central term in Germany’s culture, especially (but not limited to) the educational realm. As Bildung underwent massive transformations and has been re-interpreted multiple times throughout German history, this paper will start with a definitory exercise trying to organize the dynamics surrounding the term. Secondly, a two-fold historical context – firstly regarding the wider political and social dynamics of the time and secondly, a more (...) biographical approach focusing on Schiller – will be provided. These contextualizing efforts will be succeeded by elaborations on Schiller’s concept of Herzensbildung. The paper closes with a summary of key insights and further potential endeavors. (shrink)

The Making of the Economy uses Husserl's critique of formalism in natural science in The Crisis of the European Sciences work as the template for an analogous critique of formalism in economic science. The historical narrative focuses on the emergence of formal economic analysis out of a series of successive life-worlds, or concrete historical situations. This generates new substantive understanding of both the historical material and the current discourse of crisis surrounding economics. It will appeal to historians and philosophers of (...) economics, as well as scholars of history, philosophy, and sociology. (shrink)

Virtually all philosophers agree that for a belief to be epistemically justified, it must satisfy certain conditions. Perhaps it must be supported by evidence. Or perhaps it must be reliably formed. Or perhaps there are some other "good-making" features it must have. But does a belief's justification also require some sort of awareness of its good-making features? The answer to this question has been hotly contested in contemporary epistemology, creating a deep divide among its practitioners. Internalists, who tend to focus (...) on scientific or theoretical beliefs as the ideal, insist that such awareness is required for justification. Externalists, who think children's ordinary beliefs in obvious facts are paradigm cases of justified belief, say it isn't required. Michael Bergmann's book offers a decisive refutation of internalism and a sustained defense of externalism. (shrink)
