This paper aims to show that—and how—Plato’s notion of the receptacle in the Timaeus provides the conditions for developing a mathematical as well as a physical space without itself being space. In response to the debate whether Plato’s receptacle is a conception of space or of matter, I suggest employing criteria from topology and the theory of metric spaces as the most basic ones available. I show that the receptacle fulfils its main task–allowing the elements qua images of the Forms (...) to exist as sensible things by being that in which the elements appear, change and move–in virtue of being pure continuity. All further qualifications required for a full notion of space are derived solely from the content of the receptacle. (shrink)

This book examines the birth of the scientific understanding of motion. It investigates which logical tools and methodological principles had to be in place to give a consistent account of motion, and which mathematical notions were introduced to gain control over conceptual problems of motion. It shows how the idea of motion raised two fundamental problems in the 5th and 4th century BCE: bringing together being and non-being, and bringing together time and space. The first problem leads to the exclusion (...) of motion from the realm of rational investigation in Parmenides, the second to Zeno's paradoxes of motion. Methodological and logical developments reacting to these puzzles are shown to be present implicitly in the atomists, and explicitly in Plato who also employs mathematical structures to make motion intelligible. With Aristotle we finally see the first outline of the fundamental framework with which we conceptualise motion today. (shrink)

Fazendo parte de uma pesquisa mais abrangente e mais ambiciosa sobre a possibilidade de uma releitura do conceito wittgensteiniano de ‘sujeito da vontade’ a partir do complexo conceito de ‘prohairesis’ em Epiteto, o presente trabalho visa proceder a uma análise preliminar de ‘pessoa moral’ e de ‘dignidade humana’ tal como dados por algumas das observações dos Discursos. Para além de uma leitura do próprio Epiteto, nos serviremos igualmente dos paralelos traçados por Dragona- -Monachou entre o filósofo estoico e Wittgenstein e (...) das notas exegéticas de Stephens e Long relativamente à significação plural de ‘prohairesis’. Se para Epiteto cada um é tão somente a sua prohairesis, o que significa dizer que cada um é tão somente a sua própria decisão racional ou atitude – ou, em termos de Wittgenstein, a sua dignidade humana? A intenção deste texto é procurar por possíveis pistas que nos permitam responder a esta pergunta. (shrink)

The paper demonstrates that Parmenides’ monism is a logical consequence of his criteria for philosophy, in conjunction with the logical operators he uses, and their holistic connection. Parmenides, I argue, is the first philosopher to set out explicit criteria for philosophy, establishing as criterion not only consistency, but also what I call rational admissibility, the requirement when giving an account of something that the account be based on rational analysis and can withstand rational scrutiny. I give a detailed account of (...) the logical operators Parmenides uses in his argument and of the way in which his notion of being is tailored to fit both them and his criteria for philoso-phy.

This paper aims to delineate the class of aesthetic judgments linguistically. The main idea is that aesthetic judgments can be specified by a certain set of assertibility conditions, i.e., by norms that govern appropriate speech-acts. This idea is spelled out in detail and defended against various objections. The suggestion leads to an interesting account of aesthetic judgments that is theoretically fruitful: It provides the basis for a non-circular and satisfying characterization of the whole domain of aesthetic research and it marks (...) an important linguistic difference between aesthetic judgments and judgments of personal taste.

In the present research, we examine the relation between leader mindfulness and employee performance through the lenses of organizational justice and leader-member relations. We hypothesize that employees of more mindful leaders view their relations as being of higher leader-member exchange quality. We further hypothesize two mediating mechanisms of this relation: increased interpersonal justice and reduced employee stress. In other words, we posit that employees of more mindful leaders feel treated with greater respect and experience less stress. Finally, we predict that (...) LMX quality serves as a mediator linking leader mindfulness to employee performance—defined in terms of both in-role and extra-role performance. Across two field studies of triadic leader-employee-peer data and dyadic leader–employee data, we find support for this sequential mediation model. We discuss implications for theorizing on leadership, organizational justice, business ethics, LMX, and mindfulness, as well as practical implications. (shrink)

David Estlund holds that ultimate normative principles are insensitive to bad facts. This is a deliberately twisted appropriation of Jerry Cohen’s famous dictum that ultimate normative principles are fact-insensitive. In this paper, I will show why Estlund’s twist misses the point of Cohen’s argument. The fact-insensitivity claim is not a requirement to eliminate all facts from our normative theories because facts necessarily make these theories concessive. Instead, it may help us to locate the true origin of these concessions. In normative (...) theorizing, we have not explained why a fact supports a principle if we fail to articulate the higher-order principle in light of which that fact is normatively significant.

Anthony Brueckner argues for a strong connection between the closure and the underdetermination argument for scepticism. Moreover, he claims that both arguments rest on infallibilism: In order to motivate the premises of the arguments, the sceptic has to refer to an infallibility principle. If this were true, fallibilists would be right in not taking the problems posed by these sceptical arguments seriously. As many epistemologists are sympathetic to fallibilism, this would be a very interesting result. However, in this paper I (...) will argue that Brueckner’s claims are wrong: The closure and the underdetermination argument are not as closely related as he assumes and neither rests on infallibilism. Thus even a fallibilist should take these arguments to raise serious problems that must be dealt with somehow. (shrink)

This paper argues that processes in the sensible realm can be in accord with reason in the Timaeus, since rationality is understood here as being based on regularity, which is conferred onto processes by time. Plato uses two different temporal structures in the Timaeus, associated with the contrast there drawn between Greek and Egyptian approaches to history. The linear order of before and after marks natural processes as rational and underlies the Greek treatment of history. By contrast, a bidirectional temporal (...) structure is the basis for the Egyptian approach to historical processes: present actions are not only determined by preceding ones in the past, but can also be influenced by the future (plans, aims). This latter temporal structure is shown to be necessary for learning from history, which makes human actions more regular. (shrink)

This paper has two main goals: first, it reconstructs Aristotle’s account of measurement in his Metaphysics and shows how it connects to modern notions of measurement. Second, it demonstrates that Aristotle’s notion of measurement only works for simple measures, but leads him into a dilemma once it comes to measuring complex phenomena, like mo-tion, where two or more different aspects, such as time and space, have to be taken into account. This is shown with the help of Aristotle’s reaction to (...) one of the problems Zeno’s dichotomy paradox raises: Aristotle implicitly employs a complex measure of motion when solving this problem, while he explicitly characterizes the measure of motion as a simple measure in his Physics.

Free will has been the object of debate in the context of addiction given that addiction could compromise an individual’s ability to choose freely between alternative courses of action. Proponents of the brain-disease model of addiction have argued that a neuroscience perspective on addiction reduces the attribution of free will because it relocates the cause of the disorder to the brain rather than to the person, thereby diminishing the blame attributed to the person with an addiction. Others have worried that (...) such displacement of free will attribution would make the person with a drug addiction less responsible. Using the paradigmatic literature on the seductive allure of neuroscience explanations, we tested whether neuroscience information diminishes attributions of free will in the context of addiction and whether respondent characteristics influence these attributions and modulate the effect of neuroscience information. We performed a large-scale, web-based experiment with 2,378 German participants to explore how attributions of free will in the context of addiction to either alcohol or cocaine are affected by: (1) a text with a neurobiological explanation of addiction, (2) a neuroimage showing effects of addiction on the brain, and (3) a combination of a text and a neuroimage, in comparison to a control group that received no information. Belief in free will was measured using the FAD-Plus scale and was, subsequent to factor analysis, separated into two factors: responsibility and volition. The investigated respondent characteristics included gender, age, education, self-reported knowledge of neuroscience, substance-use disorder (SUD), and having a friend with SUD. We found that attributions of volition (in the cocaine-subsample) were reduced in the text and neuroimage-treatment compared to the control group. However, respondent characteristics such as education and self-reported knowledge of neuroscience were associated with lower attributions of responsibility for both substances, and education was associated with lower attribution of volition for the alcohol sub-sample. Interaction analyses showed that knowledge of neuroscience was found to generally decrease attribution of responsibility. Further research on attribution of free will should consider the effects of context and respondent characteristics, which appeared surprisingly larger than those induced by experimental treatments.

Comics are complex multimodal documents that make for intriguing materials to analyze with computer vision and computational linguistics. This review summarizes the growing developments in computational modeling which have been progressing to analyze visual narratives across their various substructures.

Sentences containing predicates of personal taste (for example, ‘tasty’, ‘funny’) and aesthetic predicates (for example, ‘beautiful’) give rise to an acquaintance inference: They convey the information that speakers have first-hand experience with the object of predication and they can only be uttered appropriately if that is the case. This is surprisingly hard to explain. I will concentrate on aesthetic predicates, and firstly criticize previous attempts to explain the acquaintance phenomena. Second, I will suggest an explanation that rests on a speech (...) act theoretical version of hybrid expressivism, according to which, in uttering ‘X is beautiful’ speakers perform two illocutionary acts simultaneously: an expressive and an assertive one. I will spell out this suggestion in detail and defend it against objections. Considering puzzles related to the acquaintance inference will lead to a new argument for a promising version of hybrid expressivism in meta-aesthetics. (shrink)

This is part of a two-paper project to show in detail in ways that have not been attempted before that, in the Symposium, Plato uses the language and metaphors of the Eleusinian Mysteries as a template for the ascent to the Form of Beauty; and also to explain why he might have chosen to do so. The standard accounts of the Eleusinian Mysteries come from sources that have themselves been influenced by Plato and hence are unsuitable to demonstrating the extent (...) of his exploitation of the Mysteries. This first paper offers a reconstruction of what can be known about the Eleusian Mysteries with the help of Pre-Platonic sources, by looking at material culture, archaeological remains, and pre-Platonic literature.

In Chapter 12 of the General Theory, on “The State of Long-Term Expectation,” Keynes writes: “It would be foolish, in forming our expectations, to attach great weight to matters which are very uncertain”. In a footnote to this sentence, Keynes points out that by “very uncertain” he does not mean the same as “very improbable” and refers to the chapter on “The Weight of Arguments” in his earlier Treatise on Probability. The purpose of this article, in the first place, is (...) to provide an account of, and to sort out the relations between, Keynes's views on probability, uncertainty, and the weight of arguments.

Aesthetic statements of the form ‘X is beautiful’ are evaluative; they indicate the speaker’s positive affective attitude regarding X. Why is this so? Is the evaluative content part of the truth conditions, or is it a pragmatic phenomenon (i.e. presupposition, implicature)? First, I argue that semantic approaches as well as these pragmatic ones cannot satisfactorily explain the evaluativity of aesthetic statements. Second, I offer a positive proposal based on a speech-act theoretical version of hybrid expressivism, which states that, with the (...) literal utterance of ‘X is beautiful’, we perform two illocutionary acts simultaneously, an assertive and an expressive one. I will specify this theory in detail and argue that it can satisfactorily account for the evaluative content of aesthetic statements. I will also discuss the advantages of the theory over other variants of expressivism in meta-aesthetics. (shrink)

First, we discuss issues raised with respect to the Theory of Event Coding (TEC)'s scope, that is, its limitations and possible extensions. Then, we address the issue of specificity, that is, the widespread concern that TEC is too unspecified and, therefore, too vague in a number of important respects. Finally, we elaborate on our views about TEC's relations to other important frameworks and approaches in the field like stages models, ecological approaches, and the two-visual-pathways model.

The book (in German) on “Solar Energy – challenge for research, development and international co-operation” is the report of a study group of the Akademie der Wissenschaften zu Berlin. It reviews solar thermal, photovoltaic, and bio mimetic solar energy techniques; prospects of de-central techniques in developing countries; transport and storage of solar energy; and chances for cooperation with Arabic countries and countries of the South of the former Soviet Union. The prospect of large scale energy production in arid areas, and (...) the modern potentials of conducting electricity over long distances by high-voltage DC transmission (V, 2.1) are particularly relevant for the concluding section. Political chances as well as risks were considered for reliable long term cooperation with various Arab countries on these issues. The recommendations appear to be still appropriate 25 years after the book was published, particularly the political advice in favour of cooperation between Europe and suitable countries of the Maghreb. The global time scale of implementation (discussed in chapter I, 7.2) is of the same (high) magnitude as that of other major changes in the history of technology, such as the substitution of sailing ships by steamboats which took almost a century.

Der Versohnung dient Dialektik. Das Konzept der negativen Dialektik lasst sich als das Vorhaben verstehen, Dialektik durch dialektische Mittel zu uberwinden. Doch wie geht die radikale Kritik gesellschaftlicher Verhaltnisse und traditioneller Denkformen, eine Fundamentalkritik des falschen Ganzen, zusammen mit einem emphatischen Begriff von Utopie, mit der Idee einer Versohnung von Menschheit und Natur? In dieser Frage kommt ein Spannungsverhaltnis zum Ausdruck, das das gesamte Werk Adornos pragt und sich in paradoxalen und aporetischen Gedankenfiguren ausdruckt. Diese Untersuchung rekonstruiert das negativ-utopische Denken (...) Adornos, indem es dessen Leitmotive in ideengeschichtlichen Konstellationen transparent macht. (shrink)

In-principle restrictions on the amount of information that can be gathered about a system have been proposed as a foundational principle in several recent reconstructions of the formalism of quantum mechanics. However, it seems unclear precisely why one should be thus restricted. We investigate the notion of paradoxical self-reference as a possible origin of such epistemic horizons by means of a fixed-point theorem in Cartesian closed categories due to Lawvere that illuminates and unifies the different perspectives on self-reference.

Socially assistive devices such as care robots or companions have been advocated as a promising tool in elderly care in Western healthcare systems. Ethical debates indicate various challenges. An important part of the ethical evaluation is to understand how users interact with these devices and how interaction influences users’ perceptions and their ability to express themselves. In this review, we report and critically appraise findings of non-comparative empirical studies with regard to these effects from an ethical perspective.Electronic databases and other (...) sources were queried using a comprehensive search strategy generating 9851 records. Studies were screened independently by two authors. Methodological quality of studies was assessed. For 22 reports on 21 datasets using a non-comparative design a narrative synthesis was performed.Data shows positive findings in regard to attitudes and emotional reactions of users. Varying perception of a social relation and social presence are the most commonly observed traits of interaction. Users struggle with understanding technical complexities while functionality of the devices is limited. This leads to a behavioral alignment of users towards the requirements of the devices to be able to make use of them.This evidence adds to three important ethical debates on the use of socially assistive devices in healthcare in regard to (1) reliability of existing empirical evidence to inform normative judgements, (2) ethical significance of the social presence of devices and (3) user autonomy in regard to behavioral alignment.

Mazzino Montinari nannte Die Geburt der Tragödie "Nietzsches schwierigstes Werk". Es greift auf antike Traditionen zurück und orientiert sich weltanschaulich an Schopenhauer und Wagner, dessen,Musikdrama' Nietzsche als "Wiedergeburt der Tragödie"darstellt. Bei Nietzsche selbst und in der Kulturkritik wirkte vor allem das Konzept des Dionysischen nach. Gegen die Décadence gerichtet, wurde es zum Ideogramm eines rauschhaften Lebenskults.

In lieu of an abstract, here is a brief excerpt of the content:"But I Don’t Feel It":Values and Emotions in the Assessment of Competence in Patients With Anorexia NervosaJochen Vollmann (bio)Keywordscompetence assessment, mental capacity, informed consent, psychiatry, anorexia nervosaThe respect of the self-determination of patients obliges physicians to obtain the patient's consent before providing medical treatment. One important condition for a valid informed consent is the patient's competence to make autonomous health care decisions. Therefore, a proper assessment of competence to (...) make health care decisions is crucial particularly in patients with mental disorders (Vollmann 2000; Helmchen and Vollmann 2001). In recent years, several empirical studies on the assessment of competence in patients suffering from different mental disorders have been performed using the MacArthur Competence Assessment Tool-Treatment (MacCAT-T; Grisso and Appelbaum1998). This assessment tool is based on legal standards of competence such as understanding, reasoning, appreciation, and expressing a choice. Since its first publication, the MacCAT-T has been widely accepted as a "gold standard" of competence assessment in the psychiatric literature. In recent years the MacCAT-T has been applied to patients suffering from depression, schizophrenia, dementia, angina pectoris, and normal controls (for overview, see Welie [2001] and Bauer and Vollmann [2002]).Tan and her colleagues (2006) use the MacCAT-T the first time to assess competence to make treatment decisions in patients with anorexia nervosa. Coming from clinical practice, the authors have noticed that the MacCAT-T might not work in this group of patients. Therefore, they use semi-structured interviews in addition to the MacCAT-T to identify aspects of thinking that might be relevant to the issue of competence to refuse treatment. They use grounded theory techniques for a qualitative analysis of the data as well as five brief, self-administered questionnaires to ascertain levels of psychopathology.The results of the study show that anorexia nervosa can have complex and variable effects on concentration, beliefs, and thought processing without affecting the ability to perform well on the MacCAT-T. At the same time, participants also report a change in their value system as well as in their personal identity. The authors argue that the results of their studies suggest that the competence to refuse treatment might be compromised in [End Page 289] people with anorexia nervosa in ways that are not captured by the MacCAT-T. This is an interesting finding in patients with anorexia nervosa, because in all other studies with patients suffering from mental disorders such as dementia, depression, and schizophrenia, the MacCAT-T identified more patients as limited in their competence to make health care decisions in comparison with other methods of competence assessment such as clinical judgment (Vollmann et al. 2003). The authors argue on the basis on their qualitative, semistructured interviews that anorexia nervosa–specific difficulties with a thought process and the change of values are missed by the MacCAT-T.Furthermore, Tan and her associated could not find a relationship between the participants' scores on the psychopathological scales, the MacCAT-T scores, and their difficulties expressed during the qualitative interviews, although the small size of the study precludes statistical analysis. In an earlier study, clinical dementia scales but not neuropsychological testing correlated with formal (MacCAT-T) and clinical assessment of competence. Therefore, psychopathological factors might play a different role in different subgroups of patients suffering from different mental problems. However, the idea of an objective neuropsychological model of competence assessment, again, finds no support in the presented empirical data.The qualitative data from patients with anorexia nervosa underline the problem of the cognitive bias of the MacCAT-T assessment and the illusion of value-free categories. It has been argued that the cognitive focus for the MacCAT-T is in itself a normative convention and that the MacCAT-T is missing the complexity of the process to make health care decisions in real life. Therefore, values and emotions should be considered in addition to cognitive functions in assessing competence to make health care decisions (Breden and Vollmann 2004; see also "Mental capacity" 2004). Although many authors agree that the cognitive approach of capacity assessment is important but not sufficient for the assessment of competence to make health care decisions, it remains an...

Although the computational properties of the Region Connection Calculus RCC-8 are well studied, reasoning with RCC-8 entails several representational problems. This includes the problem of representing arbitrary spatial regions in a computational framework, leading to the problem of generating a realization of a consistent set of RCC-8 constraints. A further problem is that RCC-8 performs reasoning about topological space, which does not have a particular dimension. Most applications of spatial reasoning, however, deal with two- or three-dimensional space. Therefore, a consistent (...) set of RCC-8 constraints might not be realizable within the desired dimension. In this paper we address these problems and develop a canonical model of RCC-8 which allows a simple representation of regions with respect to a set of RCC-8 constraints, and, further, enables us to generate realizations in any dimension d = 1. For three-and higher-dimensional space this can also be done for internally connected regions. (shrink)

The mind body problem is a continuing issue in philosophy. No surveys known to us have been conducted about the actual preferences of, for example, psychology students for particular preconceptions about the mind body relation. These preconceptions may have different practical implications for decisions concerning the object and method of research, the choice of explanatory device for psychological and other research data and for the approach of professionals in practice. A questionnaire comprising ten different preconceptions about the mind body relation (...) and other items was returned by 209 German students of various disciplines and by a second sample of 233 first year psychology students. Identity theory, interactionism and complementarity were preferred most. The students clearly believed that the preference for certain preconceptions has important practical implications. There were no differences between the students of different disciplines in the choice of preferred preconceptions about the mind body relation or in the view that these preconceptions are of practical importance.

After what has been termed the affective or emotional turn in sociology and many other academic fields, there is still a dearth of methodologies for systematic empirical emotion analysis in sociology. The article addresses this gap and argues that the principles of narrative analysis can be fruitfully extended to the systematic empirical investigation of emotions. A short description of key principles and tools in narrative analysis will serve as the basis for showing how the same concepts can be used to (...) gain access to the emotional side of human experience. To this end the article engages with philosophical debates to develop a specific theoretical notion of emotions—their narrative nature—and discusses the emotional nature of narrative. Specifically, this calls into question any clear-cut distinction between meaning and emotion. Based on this, the text then employs linguistic and some psychological and literary research to demonstrate and systematize key ways in which emotions can be expressed narratively as well as on the level of sentences and words. Together this forms an encompassing methodological framework that can capture the emotionality of human experience in its manifold forms. Specifically, this also addresses the problem of non-conscious emotions. (shrink)

Resume Tout au long de sa vie Reinhart Koselleck a insisté sur son appartenance à une génération marquée par la guerre et par une défaite l’une et l’autre inscrites dans une ère concentrationnaire et postconcentionnaire pour laquelle l’expérience primaire est la condition essentielle de tout travail critique de l’historien et du mémorialiste.

Representationalist accounts of mental content face the threat of the homunculus fallacy. In collapsing the distinction between the conscious state and the conscious subject, self-representational accounts of consciousness possess the means to deal with this objection. We analyze a particular sort of self-representational theory, built on the work of John von Neumann on self-reproduction, using tools from mathematical logic. We provide an explicit theory of the emergence of referential beliefs by means of modal fixed points, grounded in intrinsic properties yielding (...) the subjective aspects of experience. Furthermore, we study complications introduced by allowing for the modification of such symbolic content by environmental influences. (shrink)
