Drawing on recent work in developmental and comparative psychology, this paper argues that demonstratives function to coordinate the interlocutors' joint focus of attention, which is one of the most basic functions of human communication. The communicative importance of demonstratives is reflected in a number of properties that together characterize them as a particular word class: In contrast to other closed-class expressions, demonstratives are universal, they are generally so old that their roots cannot be traced back to other linguistic items, they (...) are among the earliest words that children learn, and they are closely tied to a particular gesture. Moreover, demonstratives play an important role in the organization of discourse and the diachronic evolution of grammar, which arguably is also motivated by their communicative function to establish joint attention.

Heideggers Verstrickung in den Nationalsozialismus war schon immer Gegenstand großer Kontroversen, doch gab es seit den Forschungen von Hugo Ott von vor 20 Jahren keine neuen Materialien mehr, auf deren Basis Heideggers Wirken beurteilt werden konnte. Holger Zaborowski hat nun erstmals umfassend bisher unbekannte Dokumente gesichtet und kann ein ganz neues und nüchternes Bild des großen Philosophen im Nationalsozialismus zeichnen.

The paper provides a formal representation of goal systems. The focus is on three properties: consistency, conflict, and coherence. An aim is to attain conceptual clarity of these properties. It is argued that consistency is adequately regarded as a property relative to the decision situation or, more specifically, the set of alternatives that the agent faces. Moreover, as a condition of rationality, consistency is stronger than some writers have claimed. Conflict is adequately regarded as a relation over subsets of a (...) given goal system and should likewise be regarded as relative to the set of alternatives that the agent faces. Coherence is given a probabilistic interpretation, based on a support relation over subsets of goal systems. (shrink)

Platonic Patterns is a reprint collection of many of Holger Thesleff's studies in Plato—spanning from 1967 to 2003. It includes three books, four articles and a new introduction by the author, which sets the general outline of his interpretation of Plato. Whereas much of the scholarship on Plato has tended to operate within the frame of one language and/or a single school of thought, Thesleff constructively combines several discoveries and theories of various scholars with his own research, focusing on (...) how Plato can be understood in his own context. The work represents small but significant breakthroughs in research on Plato from an internationally inclusive standpoint. Having previously been published mainly in Finland by scholarly societies, availability outside the Nordic countries has, up until now, been minimal. Thesleff employs his singular expertise of Greek language and literature to make innovative contributions to the study and interpretation of Plato. He thematically stresses the significance of the less overt elements found in Plato's dialogues, such as Plato's use of humor and his linguistic expression, while taking into account the chronology and/or the intended audience.

In this paper, we propose a regularity theory of causation. The theory aims to be reductive and to align with our pre‐theoretic understanding of the causal relation. We show that our theory can account for a wide range of causal scenarios, including isomorphic scenarios, omissions, and scenarios which suggest that causation is not transitive.

This book aims to lay bare the logical foundations of tractable reasoning. It draws on Marvin Minsky's seminal work on frames, which has been highly influential in computer science and, to a lesser extent, in cognitive science. Only very few people have explored ideas about frames in logic, which is why the investigation in this book breaks new ground. The apparent intractability of dynamic, inferential reasoning is an unsolved problem in both cognitive science and logic-oriented artificial intelligence. By means of (...) a logical investigation of frames and frame concepts, Andreas devises a novel logic of tractable reasoning, called frame logic. Moreover, he devises a novel belief revision scheme, which is tractable for frame logic. These tractability results shed new light on our logical and cognitive means to carry out dynamic, inferential reasoning. Modularity remains central for tractability, and so the author sets forth a logical variant of the massive modularity hypothesis in cognitive science. (shrink)

Modal logic has been applied in many different areas, as reasoning about time, knowledge and belief, necessity and possibility, to mention only some examples. In the present paper, an attempt is made to use modal logic to account for the semantics of theoretical sentences in scientific language. Theoretical sentences have been studied extensively since the work of Ramsey and Carnap. The present attempt at a modal analysis is motivated by there being several intended interpretations of the theoretical terms once these (...) terms are introduced through the axioms of a theory.

A simple explanation of theoreticity says that a term is theoretical if and only if it refers to nonobservational entities. Paradigmatic examples of such entities are electrons, neutrinos, gravitational forces, genes etc. There is yet another explanation of theoreticity: a theoretical term is one whose meaning becomes determined through the axioms of a scientific theory. The meaning of the term ‘force’, for example, is seen to be determined by Newton’s laws of motion and further laws about special forces, such as (...) the law of gravitation. Theoreticity is a property that is commonly applied to both expressions in the language of science, and referents and concepts of such expressions. Objects, relations and functions as well as concepts thereof may thus qualify as theoretical in a derived sense. (shrink)

Most recent accounts of personal autonomy acknowledge that the social environment a person lives in, and the personal relationships she entertains, have some impact on her autonomy. Two kinds of conceptualizing social conditions are traditionally distinguished in this regard: Causally relational accounts hold that certain relationships and social environments play a causal role for the development and on-going exercise of autonomy. Constitutively relational accounts, by contrast, claim that autonomy is at least partly constituted by a person’s social environment or standing. (...) The central aim of this paper is to raise the question how causally and constitutively relational approaches relate to the fact that we exercise our autonomy over time. I argue that once the temporal scope of autonomy is opened up, we need not only to think differently about the social dimension of autonomy. We also need to reconsider the very distinction between causally and constitutively relational accounts, because it is itself a synchronic (and not a diachronic) distinction. (shrink)

Background: Informed consent is a legal as well as ethical prerequisite in clinical research. For dementia research, informed consent can be a problem if subjects with dementia, whose capacity for understanding and thus also decision making might be limited, are to be exam- ined. This might result in exclusion of dementia patients from research, as capacity for understanding and decision making are often equated with the ability for rational decision making. However, this valuation has been criticized at times for attaching (...) too much impor- tance to the cognitive aspect of decision making. -/- Methods: This qualitative study investigates the actual consent procedure of a clini- cal research study in Germany with regard to dementia patients’ subjective and objective understanding of informed consent information. Research participants were ten dementia patients, who volunteered in two clinical research studies, as well as their caregivers. Data were collected by use of semi-structured interviews. -/- Results: It was determined that the patients’ comprehension of informed consent infor- mation was rather limited. However, a number of patients were quite aware of this. In con- trast, all caregivers claimed to have fully understood the provided information, while their objective comprehension was also incomplete. Several participants indicated that they did not attach much importance to the information given in the consent procedure and that their consent did not primarily depend on this information. Rather, participation in the research study for them seemed to be more of a problem-focused coping strategy for dealing with their diagnosis of dementia. -/- Conclusion: For research ethics these results raise the question whether the currently prevailing emphasis on the cognitive aspect of autonomous decision making, i.e., compre- hension, may be too one-sided, and to what extent the “volitional” aspect in giving consent should be given greater consideration.

This paper offers a review of research on demonstratives from an interdisciplinary perspective. In particular, we consider the role of demonstratives in current research on language universals, language evolution, language acquisition, multimodal communication, signed language, language and perception, language in interaction, spatial imagery, and discourse processing. Traditionally, demonstratives are analyzed as a particular class of spatial deictics. Yet, a number of recent studies have argued that space is largely irrelevant to deixis and that demonstratives are primarily used for social and (...) interactive purposes. Synthesizing findings in the literature, we conclude that demonstratives are a very special class of linguistic items that are foundational to both spatial and social aspects of language and cognition.

Structural realism is sometimes said to undermine the theory underdetermination (TUD) argument against realism, since, in usual TUD scenarios, the supposed underdetermination concerns the object-like theoretical content but not the structural content. The paper explores the possibility of structural TUD by considering some special cases from modern physics, but also questions the validity of the TUD argument itself. The upshot is that cases of structural TUD cannot be excluded, but that TUD is perhaps not such a terribly serious anti-realistic argument.

The paper is a kind of opinionated review paper on current issues in the debate about Structural Realism, roughly the view that we should be committed in the structural rather than object-like content of our best current scientific theories. The major thesis in the first part of the paper is that Structural Realism has to take structurally derived intrinsic properties into account, while in the second part key elements of aligning Structural Realism with a Humean framework are outlined.

In this paper, a new account of empirical claims in structuralism is developed. Its novelty derives from the use that is made of the linguistic approach to scientific theories despite the presumed incompatibility of structuralism with that approach. It is shown how the linguistic approach can be applied to the framework of structuralism if the semantic foundations of that approach are refined to do justice to the doctrine of indirect interpretation of theoretical terms. This doctrine goes back to Carnap but (...) has been advanced until the present day without a proper semantic explanation. (shrink)

The present paper aims at a synthesis of belief revision theory with the Sneed formalism known as the structuralist theory of science. This synthesis is brought about by a dynamisation of classical structuralism, with an abductive inference rule and base generated revisions in the style of Rott (2001). The formalism of prioritised default logic (PDL) serves as the medium of the synthesis. Why seek to integrate the Sneed formalism into belief revision theory? With the hybrid system of the present investigation, (...) a substantial simplification of the ranking information that is necessary to define revisions and contractions uniquely is achieved. This system is, furthermore, expressive enough to capture complex and non-trivial scientific examples. It is thus closely related to a novel research area within belief revision theory which addresses the dynamics of scientific knowledge. (shrink)

Ohne den Verleger Hermann Niemeyer hätte es keine DVjs gegeben. Am Beispiel dieser Zeitschrift untersucht der Beitrag auf der Grundlage unveröffentlichter Korrespondenzen, unter welchen historischen Bedingungen und Konstellationen eine funktionierende Infrastruktur für wissenschaftliches Publizieren im Deutschland der 1920er und 1930er Jahre geschaffen und unterhalten wurde.

In line with some promising studies dealing with particular academic speech events at university level, this article analyses recordings of another established form of spoken academic discourse at university outside the classroom; viz. office hour interactions between faculty and students. Office hour appointments at two German universities were video-recorded and subsequently transcribed according to conventional transcription notations. The study draws upon two levels of analysis. First, a phasal sectioning is performed to highlight different stages in the organization of office hour (...) talk, which are decisive for a fruitful consultation and indispensable to conform to official standards in academia. Concurrently, on an interactional level, findings from conversation analysis are used to display how this form of consultation unfolds, and how participants orient towards both the respective institutional tasks as well as the discourse partner. What becomes clear from this preliminary study is that the academic significance of office hours is often underestimated. Those cases in which complex academic matters are under discussion demand careful action-taking and mutual orientation by both participants. This face-to-face encounter has multiple consequences for the academic and the social relationship between teacher and student, as well as for pedagogical practices and institutional circumstances at large.

Ein Vergleich zwischen Fichte und Nietzsche mag zunächst überraschend anmuten. Nietzsches Beschäftigung mit Fichtes Philosophie war nur marginal und seine Äußerungen fielen dann auch eher polemisch aus. Eine Einflußphilologie ist sicherlich kein weitreichendes Unterfangen. Warum also den Lebensbegriff gerade dieser beiden Philosophen gegenüberstellen?

The aim of this paper is twofold: First, to present an examination of the principles underlying gauge field theories. I shall argue that there are two principles directly connected to the two well-known theorems of Emmy Noether concerning global and local symmetries of the free matter-field Lagrangian, in the following referred to as "conservation principle" and "gauge principle". Since both these express nothing but certain symmetry features of the free field theory, they are not sufficient to derive a true interaction (...) coupling to a new gauge field. For this purpose it is necessary to advocate a third, truly empirical principle which may be understood as a generalization of the equivalence principle. The second task of the paper is to deal with the ontological question concerning the reality status of gauge potentials in the light of the proposed logical structure of gauge theories. A nonlocal interpretation of topological effects in gauge theories and, thus, the non-reality of gauge potentials in accordance with the generalized equivalence principle will be favoured. (shrink)

The desideratum of semantic interoperability has been intensively discussed in medical informatics circles in recent years. Originally, experts assumed that this issue could be sufficiently addressed by insisting simply on the application of shared clinical terminologies or clinical information models. However, the use of the term ‘ontology’ has been steadily increasing more recently. We discuss criteria for distinguishing clinical ontologies from clinical terminologies and information models. Then, we briefly present the role clinical ontologies play in two multicentric research projects. Finally, (...) we discuss the interactions between these different kinds of knowledge representation artifacts and the stakeholders involved in developing interoperational real-world clinical applications. We provide ontology engineering examples from two EU-funded projects. (shrink)

We aim to devise a Ramsey test analysis of actual causation. Our method is to define a strengthened Ramsey test for causal models. Unlike the accounts of Halpern and Pearl ([2005]) and Halpern ([2015]), the resulting analysis deals satisfactorily with both over- determination and conjunctive scenarios.

The connection of the structure of statistical selection procedures with measure theory is investigated. The methods of measure theory are applied in order to analyze a mathematical description of preparation and registration of physical systems that is used by G. Ludwig for a foundation of quantum mechanics.

This paper aims to set forth Carnapian structuralism, i.e., a syntactic view of the structuralist approach which is deeply inspired by Carnap’s dual level conception of scientific theories. At its core is the axiomatisation of a metatheoretical concept AE(T) which characterises those extensions of an intended application that are admissible in the sense of being models of the theory-element T and that satisfy all links, constraints and specialisations. The union of axiom systems of AE(T) (where T is an element of (...) the theory-net N) will allow us to present scientific theories in an axiomatic fashion so that deductive reasoning in science can be formalised. Thereupon defeasible and paraconsistent means of reasoning will be introduced. The logical study of scientific reasoning is the key motivation of Carnapian structuralism. A further motivation is to help overcome the syntactic-semantic split in the philosophy of science. (shrink)

A central topic in the logic of science concerns the proper semantic analysis of theoretical sentences, that is sentences containing theoretical terms. In this paper, we present a novel choice-semantical account of theoretical truth based on the epsilon-term definition of theoretical terms. Specifically, we develop two ways of specifying the truth conditions of theoretical statements in a choice functional semantics, each giving rise to a corresponding logic of such statements. In order to investigate the inferential strength of these logical systems, (...) we provide a translation of each truth definition into a modal definition of theoretical truth. Based on this, we show that the stronger notion of choice-semantical truth captures more adequately our informal semantic understanding of scientific statements. (shrink)

There is a growing consensus that the mental lexicon contains both abstract and word-specific acoustic information. To investigate their relative importance for word recognition, we tested to what extent perceptual learning is word specific or generalizable to other words. In an exposure phase, participants were divided into two groups; each group was semantically biased to interpret an ambiguous Mandarin tone contour as either tone1 or tone2. In a subsequent test phase, the perception of ambiguous contours was dependent on the exposure (...) phase: Participants who heard ambiguous contours as tone1 during exposure were more likely to perceive ambiguous contours as tone1 than participants who heard ambiguous contours as tone2 during exposure. This learning effect was only slightly larger for previously encountered than for not previously encountered words. The results speak for an architecture with prelexical analysis of phonological categories to achieve both lexical access and episodic storage of exemplars. (shrink)

In this paper, we analyse actual causation in terms of production. The latter concept is made precise by a strengthened Ramsey Test semantics of conditionals: \ iff, after suspending judgement about A and C, C is believed in the course of assuming A. This test allows us to verify or falsify that an event brings about another event. Complementing the concept of production by a weak condition of difference-making gives rise to a full-fledged analysis of causation.

In the history of zoology the English anatomist Morrison Watson (1845–1885) is considered to be the discoverer of the masculinized sexual organs of the spotted hyena. Beginning in 1877, Watson had published a series of anatomical studies on the spotted hyena (Watson, 1877, 1878, 1881, Watson and Young, 1879), in which he, in which he for the first time made public the anatomical peculiarities of the female spotted hyena’s genitalia. This scientific achievement is well documented. But now we can also (...) state that a hundred years before Watson the Dutch amateur zoologist Robert Jacob Gordon (1743–1795), while serving in the Scots Brigades at the Cape of Good Hope, had already made the same discovery and merely unfortunate personal circumstances prevented publication. During his stay at the Cape, Gordon had studied spotted hyenas intensively and recorded his observations in accurate drawings and comments. These drawings have been preserved as part of a large collection of animal drawings entitled Gordon Atlas. With his discovery, Gordon actually was the first to provide empirical evidence of a “curious and inexplicable case of dimorphism” (Darwin on a beetle) in mammalians, long before Étienne Geoffrey Saint-Hilaire (Cours de l’histoire naturelle des mammifères, 1829) started examining masculinized sexual organs in the mole or Darwin recognized the importance of sexual dimorphism (Descent of Man, 1871). In this paper we reproduce for the first time all hyena drawings from the Gordon Atlas, including Gordon’s handwritten notes in the margins in the original Dutch and in translation. Additionally, we briefly delineate the knowledge about the South African spotted hyena in Gordon’s time and indicate that we doubt Watson’s explanation for the age-old confusion about the hyena.
