Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? (...) Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

In the leadership literature of the past 100 years or so, rhetoric has been a topic for a long time and ethics was introduced some 30 years ago. However, the three topics, leadership, rhetoric, and ethics, have not been connected. This is astonishing because when ethical leadership made its comeback, scholars acknowledged the debt that ethical leadership owes to Aristotelian ideas. For Aristotle, leadership, ethics, and rhetoric were inseparable: without ethics, there could neither be good leadership nor rhetoric, and rhetoric (...) was the bridge from leader to follower and back. Aristotle is known as the practical philosopher and we argue that closing this major lacuna in leadership theory, would be beneficial for practice too and would help prevent Theranos-like scandals. The lacuna lies in what some call a Machiavellian view of leadership and rhetoric: both are regarded as amoral tools to achieve given ends. Aristotle would bristle at that idea. Both, leadership and rhetoric, to be good, must aim at the noble. The noble is not dictated by a heroic despot nor by a selfless saint but is understood by a leader because s/he is a socially embedded individual. We argue that leadership should be understood as personal development, that organisational rules must not inhibit virtue, that leadership is more about listening than talking, that synthesising that which is heard is central, and finally, that the common, not the collective, good is the goal of leadership.

All conceptions of equal opportunity draw on some distinction between morally justified and unjustified inequalities. We discuss how this distinction varies across a range of philosophical positions. We find that these positions often advance equality of opportunity in tandem with distributive principles based on merit, desert, consequentialist criteria or individuals' responsibility for outcomes. The result of this amalgam of principles is a festering controversy that unnecessarily diminishes the widespread acceptability of opportunity concerns. We therefore propose to restore the conceptual separation (...) of opportunity principles concerning unjustified inequalities from distributive principles concerning justifiable inequalities. On this view, equal opportunity implies that that morally irrelevant factors should engender no differences in individuals' attainment, while remaining silent on inequalities due to morally relevant factors. We examine this idea by introducing the principle of ‘opportunity dominance' and explore in a simple application to what extent this principle may help us arbitrate between opposing distributive principles. We also compare this principle to the selection rules developed by John Roemer and Dirk Van de Gaer. (shrink)

I distinguish between Old Contextualism, New Contextualism, and the Multiple Concepts Theory. I argue that Old Contextualism cannot handle the following three problems: (i) the disquotational paradox, (ii) upward pressure resistance, (iii) inability to avoid the acceptance of skeptical conclusions. New Contextualism, in contrast, can avoid these problems. However, since New Contextualism appears to be a semanticized mirror image of MCT, it remains unclear whether it is in fact a genuine version of contextualism.

As human–machine teams are being considered for a variety of mixed-initiative tasks, detecting and being responsive to human cognitive states, in particular systematic cognitive states, is among the most critical capabilities for artificial systems to ensure smooth interactions with humans and high overall team performance. Various human physiological parameters, such as heart rate, respiration rate, blood pressure, and skin conductance, as well as brain activity inferred from functional near-infrared spectroscopy or electroencephalogram, have been linked to different systemic cognitive states, such (...) as workload, distraction, or mind–wandering among others. Whether these multimodal signals are indeed sufficient to isolate such cognitive states across individuals performing tasks or whether additional contextual information (e.g., about the task state or the task environment) is required for making appropriate inferences remains an important open problem.In this paper, we introduce an experimental and machine learning framework for investigating these questions and focus specifically on using physiological and neurophysiological measurements to learn classifiers associated with systemic cognitive states like cognitive load, distraction, sense of urgency, mind wandering, and interference. Specifically, we describe a multitasking interactive experimental setting used to obtain a comprehensive multimodal data set which provided the foundation for a first evaluation of various standard state-of-the-art machine learning techniques with respect to their effectiveness in inferring systemic cognitive states. While the classification success of these standard methods based on just the physiological and neurophysiological signals across subjects was modest, which is to be expected given the complexity of the classification problem and the possibility that higher accuracy rates might not in general be achievable, the results nevertheless can serve as a baseline for evaluating future efforts to improve classification, especially methods that take contextual aspects such as task and environmental states into account.

The late nineteenth- and early twentieth-century debate over ‘internal’ and ‘external’ relations is well explored, as far as its course in Britain is concerned. F. H. Bradley’s idealistic internalism, on the one hand, and Bertrand Russell’s realistic externalism, on the other, were at the center of this debate. Less well known, however, is that there was also a discussion about relations in the United States at the time. The central figures in this discussion were Edward Gleason Spaulding and John Dewey. (...) Like Russell, Spaulding advocated a realist-inspired externalism, while Dewey criticized this viewpoint from a pragmatist perspective. The aim of the present paper is to reconstruct the exchange between Spaulding and Dewey and to elaborate the specifics of this exchange. In doing so it will emerge, among other things, that, in contrast to Bradley’s idealist rejection of externalism, Dewey’s pragmatist attempt at a refutation was more in line with common sense and science and that Spaulding’s version of externalism differed markedly from Russell’s in its strong empirical orientation. Overall, an undeservedly forgotten chapter in the history of early twentieth-century American philosophy is revisited and reassessed. (shrink)

This paper examines Ralph Barton Perry's analysis of the ‘ego-centric predicament’. It will be shown that Perry convincingly argued against prevailing contemporary versions of idealism and that it makes perfectly good sense to consider him a precursor of subsequent trends in American analytic philosophy. Perry's appraisal and promotion of the contemporary logic of relations in the framework of early twentieth-century American neorealism provides further evidence of his being a proto-analytic philosopher. His personal acquaintance with Bertrand Russell proved instructive in this (...) regard. On the whole, Perry's distinctive approach to philosophy was instrumental in establishing the analytic style of reasoning in the United States. This paper is devoted to substantiating this claim. It is thus hoped that a clearer picture of early twentieth-century American philosophy will begin to emerge. (shrink)

In the article ‘Represent Me: Please! Towards an Ethics of Digital Twins in Medicine’, I analysed and tried to better understand the main ethical challenges associated with Digital Twins. For those who are just entering the debate with this article: DT is a metaphor for a bundle of artificial intelligence driven simulation technologies that constantly, in real time and ad personam simulate single or multiple parts of the body and make predictions about future health states based on these simulations. My (...) argument addresses the need to look at the breadth of challenges through a perspective of representation. From such a take, key consequences can be drawn for the further development of such technologies, the required means of control and not least the way to think about the interaction between humans and ‘their’ simulations. I am very grateful for the subsequent suggestions, criticisms and further arguments, which have helped me to elaborate my arguments more clearly and have led to a substantial advancement of the debate and the discussion about ethical questions in dealing with DT. Jenny Blumenthal-Barby,1 Deborah Lupton,2 Jenny Krutzinna,3 Janina Loh,4 Brent Mittelstadt,5 Sven Nyholm,6 Daniel Tigard7 and Max Tretter8 have made excellent points, which, in the following, I will not be able to reply to individually and in detail. In this response, I will try to bundle the open points and questions along the comments and considerations mentioned above and attempt to outline their significance for an ethics of DT. Four challenges seem to be central. A first point addresses anthropological issues. It is concerned …. (shrink)

During the fall of 2001 (October 22–25), The Norwegian Radiation Protection Authority (NRPA) and the Agricultural University of Norway arranged a consensus conference on the protection of the environment against ionising radiation. The motive for the conference was the need to study the ethical and philosophical basis for protection of nature in its own right. The conference was funded by Nordic Nuclear Safety Research (NKS), in cooperation with the International Union of Radioecology (IUR). The National Committee for Research Ethics in (...) Science and Technology (NENT) was hired as facilitators for the consensus process. This paper will give a brief outline of the aims and method of the conference, distinguishing these from other kinds of consensus conferences. The paper ends with some general reflections on the appropriateness of seeking consensus on ethics-related issues among experts. (shrink)

John Hyman’s Action, Knowledge, and Will achieves what is increasingly rare in academic philosophy. It is both ambitious and controlled, wide-ranging and pointe.

Whether deconstruction is relevant to environmental philosophy, and if so, in what ways and with what transformations, has been subject to considerable debate in recent years. I will begin by discussing some reservations regarding deconstruction’s relevance to environmental thought, and argue that they stem from an older misreading of Derrida’s work in particular as hostile to the natural sciences, and as a cultural textualism of relevance only to the interiority of a traditional canon, but unable to reach the materiality of (...) the outside environment. This attempt at refutation will permit a better understanding of the deconstructive argument for what has been called an ‘originary environmentality’ of life. On this basis, I seek to argue that deconstruction tends to be most promising to environmental questions when it shows responses to the call, not primarily for a new ethics, but for far-ranging analyses of our conception of politics. The reason for this lies in the overall deconstructive goal of exposing political and legal sovereignty, including its modern democratic understanding, to what I will elaborate as contextual or environmental finitude.

Verfassungsgerichtliche Institutionen- und Kompetenzprofile finden sich gegenwärtig in vielen politischen Gemeinwesen. Dort, wo nicht nur die Prozeduren, sondern sogar die Inhalte des politischen Prozesses dem letztverbindlichen Richterspruch unterliegen, entfaltet die Verfassungsrechtsprechung eine besonders nachhaltige und weitreichende Wirkung. Höchstrichterliche Entscheidungen prägen politisches System und Rechtskultur in diesem Fall derart, dass der Jurisdiktion der Status einer souveränen Instanz zukommt. Mit der Legitimität dieser Version von Verfassungsgerichtsbarkeit befasst sich das vorliegende Werk. Es behandelt das Thema Verfassungsgerichtsbarkeit als Abstraktum, bringt die Mannigfaltigkeit der Erscheinungsformen (...) von (Verfassungs-)Gerichtsbarkeit in eine gedankliche Ordnung, konzipiert Verfassungsgerichtsbarkeit als die institutionell verankerte gerichtliche Überprüfbarkeit sämtlicher staatlicher Akte und erörtert das "Ob und Überhaupt" von Verfassungsgerichtsbarkeit im demokratischen Verfassungsstaat. Der Studie zufolge sprechen pragmatische Gründe sowohl für die Rechtfertigbarkeit einer solchen gerichtlichen Aufsicht als auch für die Geeignetheit der Gerichtsbarkeit hierzu. Prinzipientheoretische Eindeutigkeit hingegen lasse sich weder für noch gegen die Institution der umfassenden Verfassungsgerichtsbarkeit anführen. Aktuelle Bedeutung besitzt die Problematik des legitimen verfassungsgerichtlichen Wirkens insbesondere im Blick auf die Rechts- und Herrschaftsordnung der Europäischen Union. (shrink)

In 2.14 Propertius promises rich donations to Venus, to be attached to a „columna“ (v. 25). This column is often thought to be part of a temple, but such an interpretation raises problems. One reading is that columna means a single votive column, well-known in Roman (and Greek) religious praxis and in visual arts. With such a reading „columna“ gains in sacral importance. Then again, single columns have been used as Roman victory monuments: With that in mind the „columna“ can (...) equally be understood in the semantics of a military success, which is essential for the whole elegy. Propertius’ „columna“ is much more than only a place to attach „magna dona“ (v. 25). (shrink)

Der Beitrag setzt die Praxis der Agitproptruppen im Deutschland der Jahre um 1930 in Beziehung zur Praxis gegenwärtiger Performancekollektive. In dieser historisierenden Perspektive wird die Heterogenität von Gruppenstrukturen und Entscheidungsprozessen deutlich, die in verschiedenen Phasen der Kunstgeschichte und des Kunstdiskurses mit dem Kollektivbegriff bezeichnet wurden. Um zu verstehen, warum sich Kollektive bisweilen straff geführt und geradezu autoritär, in anderen Fällen aber offen, demokratisch und an Gleichheitspostulaten orientiert zeigen, ist einerseits das Verhältnis der jeweiligen Kollektive zu großen, dominanten Institutionen zu betrachten. (...) Andererseits soll einem Zusammenhang zwischen der künstlerisch-ästhetischen Ausrichtung der Kollektive und ihren Entscheidungsstrukturen nachgegangen werden: Die Abwendung vom klassischen Theaterdispositiv ermöglicht es Kollektiven, die sich zu anderen Künsten und Medien öffnen, auch andere, offenere Entscheidungsstrukturen zu entwickeln, als sie etwa aus dem Stadt- und Staatstheater vertraut sind.

Jan Krajíček posed the following problem: Is there is a generalization result in the theory of real closed fields of the form: If A is provable in length k for all n ϵ ω , then A is provable? It is argued that the answer to this question depends on the particular formulation of the “theory of real closed fields.” Four distinct formulations are investigated with respect to their generalization behavior. It is shown that there is a positive answer to (...) Krajíček's question for 1. the axiom system RCF of Artin-Schreier with Gentzen's LK as underlying logical calculus, 2. RCF with the variant LK B of LK allowing introduction of several quantifiers of the same type in one step, 3. LK B and the first-order schemata corresponding to Dedekind cuts and the supremum principle. A negative answer is given for 4. any system containing the schema of extensionality. (shrink)

The length of resolution proofs is investigated, relative to the model-theoretic measure of Herband complexity. A concept of resolution deduction is introduced which is somewhat more general than the classical concepts. It is shown that proof complexity is exponential in terms of Herband complexity and that this bound is tight. The concept of R-deduction is extended to FR-deduction, where, besides resolution, a function introduction rule is allowed. As an example, consider the clause P Q: conclude P) Q, where a, f (...) are new function symbols extending Herbrand's universe. P ()Q from Q) and Skolemization). By modification of a construction of Statman it is shown that FR-deductions may be nonelementarily shorter than R-deductions . Finally it is proved that FR-deduction has weaker effects only if clausal logic is restricted to Horn logic. (shrink)

The paper presents the first known evidence of the so called “late ancient philosophical curriculum” ethics, physics, theology, by demonstrating that this division of philosophy can be found already in the introduction of Aspasios’s commentary on the Nicomachean Ethics. It is argued that this text can be dated roundabout 70 years earlier than the earliest reliable testimony hitherto known in Clemens Alexandrinus. Furthermore, the paper presents some neglected evidence for this curriculum from different works of Alexander of Aphrodisias. Based upon (...) those texts and a new analysis of some already well-known passages, it proposes to regard the scheme ethics, physics, theology as an originally Aristotelian model, which has been later taken over by Platonists. This does not rule out the possibility that Platonic ideas have been influenced the scheme at a very early date. (shrink)

Definition of the problem: Is it the brain that makes a human being a person? This anthropological question has been raised because of the findings of modern human brain research, and there are severe ethical consequences anew: If the appropriate anthropological answer is yes, then all invasive research would be problematic, because one would touch the basis of human essence. The problem is that the two major philosophical paradigms that offer an answer to the anthropological question, dualism and monism, have (...) opposing concepts. Arguments: This paper argues that the error of these two paradigms is that they understand the human body and the human mind as ’res’– as things. The explanation of the human being as an interactive unit of body and mind is impossible in both paradigms. A third anthropological view that tries to make that understandable is the anthropology of the Hebrew Bible. It does assume the category ’thing’ while speaking about humans, it presumes the category ’aspect’. There is no Hebrew word for ’mind’ in contrast to ’body’ or vice versa. The biblical language only knows terms for the unity of human beings seen under a certain aspect. Conclusion: Here, the body and thus the brain are important and necessary condition for human essence, but this is not a sufficient explanation for the human personality. Invasive research on the human brain is here neither generally forbidden nor tolerated – one has to demonstrate in every single case whether the planned operation touches regions that are crucial for the personality of the human subject.

Expert athletes are determined to make faster and better decisions, as revealed in several simple heuristic studies using verbal reports or micro-movement responses. However, heuristic decision-making experiments that require motor responses, also being considered as the embodied-choice experiments, are still underrepresented. Furthermore, it is less understood how decision time and confidence depend on the type of embodied choices players make. To scrutinize the decision-making processes, this study investigated the embodied choices of male athletes with different expertise in a close-to-real-life environment; (...) 22 elite, and 22 amateur team handball players performed a sport-specific embodied-choice test. Attack sequences were shown to the players, who had to choose between four provided options by giving a respective sport-specific motor response. We analyzed the frequencies of specific choices and the best choice, as well as the respective decision time and decision confidence. Elite and amateur players differed in the frequencies of specific choices, and elite players made the best choice more often. Slower decision times of elite players were revealed in specific choices and in best choices, the confidence of decisions was rated equally high by both player groups. Indications are provided that elite players make better choices rather slower, instead of faster. We suppose this is due to specific sensorimotor interactions and speed-accuracy-tradeoffs in favor of accuracy in elite players. Our findings extend expert decision-making research by using an embodied-choice paradigm, highlighting considerations of decision time and confidence in future experiments. (shrink)
