It is controversial whether Wittgenstein's philosophy of mathematics is of critical importance for mathematical proofs, or is only concerned with the adequate philosophical interpretation of mathematics. Wittgenstein's remarks on the infinity of prime numbers provide a helpful example which will be used to clarify this question. His antiplatonistic view of mathematics contradicts the widespread understanding of proofs as logical derivations from a set of axioms or assumptions. Wittgenstein's critique of traditional proofs of the infinity of prime numbers, specifically those of (...) Euler and Euclid, not only offers philosophical insight but also suggests substantive improvements. A careful examination of his comments leads to a deeper understanding of what proves the infinity of primes. (shrink)

We consider a natural-language sentence that cannot be formally represented in a first-order language for epistemic two-dimensional semantics. We also prove this claim in the “Appendix” section. It turns out, however, that the most natural ways to repair the expressive inadequacy of the first-order language render moot the original philosophical motivation of formalizing a priori knowability as necessity along the diagonal.

Nietzsche’s challenge to philosophy has two main prongs. The first is the challenge intrinsic to philosophy, the theoretical challenge to discover the truth; in Nietzsche this ultimately became the challenge to understand the perhaps deadly truth that to be is to be will to power and nothing besides—what Strauss called the “fundamental fact.” The second is the chief derivative challenge of philosophy proper, the practical challenge compelling philosophy to translate truth or an approximation of truth into a culturally livable form—what (...) Strauss recognized in Nietzsche as the challenge for philosophy to rule religion. The two parts of my paper deal with these two challenges. Besides his theoretical and practical challenges, Nietzsche makes a subsidiary, tactical challenge especially relevant to Strauss, a challenge regarding truth-telling or esotericism, namely, telling the truth about philosophy. I will deal with that challenge as an interlude. (shrink)

Raimund Bleischwitz and Martina Etzbach respond to the question how the global warming foracested by climate research will change the relations between the North and the South. After a description of ecological and socio-economic implication of the potential catastrophy of a global climate change the authors discuss possible instrument of an international climate policy. The considerations focus on institutional problems, especially on possible actors and borlies responsible for a global environmental policy.

… philosophy must be a practice as much as it is a theory.Leah Kalmanson, Cross-Cultural Existentialism, p. 1In the face of the sheer quantity of life's uncertainties, Leah Kalmanson's Cross-Cultural Existentialism provides more than a novel take on existential theory ; following the mantra of European existentialists that "philosophies are meant to be lived," Cross-Cultural Existentialism introduces the reader to a series of practices central to the Ruist tradition required to make philosophy "a concrete attitude, a way of life". Kalmanson's (...) turn to the East Asian tradition is largely motivated by her assessment that the... (shrink)

This special issue collects the results of the workshop “The Philosophy of Keith Lehrer” which was held in October 2010 at the University of Graz, Austria, where Keith Lehrer is Honorary Professor and Honorary Doctor of Philosophy. Over the last decades Lehrer has been a frequent visitor in Graz. As a much admired teacher and scholar, he has decisively influenced generations of students and inspired many of them to choose an academic career. The guest-editors, who organized the workshop, want to (...) thank all the participants for making the workshop a success. Special thanks go to Keith Lehrer for commenting on each talk at the workshop as well as each contribution to this volume. We are grateful to Stewart Cohen for publishing this issue in his prestigious journal. This volume honors Lehrer and his invaluable contributions to philosophy. It contains five chapters, each illustrating the impressively wide range of his philosophy. The chapters are divided into discussions and applications of Lehrer´s work in theoretical knowledge, practical knowledge, philosophy of language, and philosophy of mind. The fifth and final chapter contains his replies to all of the contributions. (shrink)

The phenomenological understanding of empathy as the direct experiencing of the mental states (feelings, intentions, moods) of others eschews the identification of empathy with caring. At the same time, it leaves open the possibility of sadistic pleasure, indifference, or malice as consequences of empathic experience. In this paper, I intend to defend the place of caring as an inseparable part of the empathic experience, specifically when understood as direct perception. My defense relies on (a) conceiving of attentive concern as a (...) perceptual predisposition, and (b) understanding the caring responsiveness of the empathizer as embedded in her direct perception of the empathee's mental states. My claim proceeds by three steps. Firstly, I will present the need to include caring within empathy through the problem that arises from excluding it. Secondly, I will argue for the presence of active responsiveness, inherent in the phenomenological concept of perception and expressed more explicitly in its Gibsonian understanding. Thirdly, I will propose my understanding of attentive concern as a predisposition, which together with the intentionality attributed to the other (itself also a disposition) forms the pre-perceptual basis for identifying empathy with caring.

The SARS-CoV-2 pandemic has highlighted the interdependency of healthcare systems and research organizations on manufacturers and suppliers of personnel protective equipment and the need for well-trained personnel who can react quickly to changing working conditions. Reports on challenges faced by research laboratory workers are rare in contrast to the lived experience of hospital health care workers. We report on experiences gained by RLWs who significantly contributed to combating the pandemic under particularly challenging conditions due to increased workload, sickness and interrupted (...) PPE supply chains. RLWs perform a broad spectrum of work with SARS-CoV-2 such as autopsies, establishment of virus cultures and infection models, development and verification of diagnostics, performance of virus inactivation assays to investigate various antiviral agents including vaccines and evaluation of decontamination technologies in high containment biological laboratories. Performance of autopsies and laboratory work increased substantially during the pandemic and thus led to highly demanding working conditions with working shifts of more than eight hours working in PPE that stressed individual limits and also the ergonomic and safety limits of PPE. We provide detailed insights into the challenges of the stressful daily laboratory routine since the pandemic began, lessons learned, and suggest solutions for better safety based on a case study of a newly established HCBL designed for autopsies and research laboratory work. Reduced personal risk, increased resilience, and stress resistance can be achieved by improved PPE components, better training, redundant safety measures, inculcating a culture of safety, and excellent teamwork.

It has recently been suggested that seeing-in can sometimes be central to the aesthetic appreciation of pictures. The key concept is that of inflected seeing-in, a special case of picture perception connected with the wollheimean notion of twofoldness. In order to further understand inflection, I focus on Nanays account. He holds that conscious attention is essential to inflected seeing-in. I agree, but I suggest our conceptualization of the properties of the pictorial vehicle is necessary to account for the complexity of (...) this experience. Developing a suggestion from Wollheim, I then characterize inflected pictorial experience in terms of different pictorial hows and our grasping of them. This makes it possible to account for the intuitive link between properties of experiences and properties of the pictures that trigger them, as well as for the appealing idea that our conscious apprehension of the way a picture depicts its subject - what I may call the pictorial hows - plays a significant role in our aesthetic experience of pictures. I finally look at these results in the more general perspective of a representationalist theory of aesthetic experience. (shrink)

This article explores how Alzheimer’s disease caregivers struggle under the impact of a parent’s memory loss on their own personality. In particular, it analyses how caregivers perceive and, thus, present their experiences of the ever intensifying caregiving activity in terms of a ‘journey’. In doing so, this work takes into account both the patient’s continuing bodily as well as cognitive decline and its intricately linked influence on the caregiver’s physical and emotional stability. Equally, this study investigates how caregivers portray memory (...) loss, and how their portrayal fits into our conceptualisation of illness narratives and the culture of autobiographical writing.

The papers collected in this volume exemplify some of the trends in current approaches to logic, language and computation. Written by authors with varied academic backgrounds, the contributions are intended for an interdisciplinary audience. The first part of this volume addresses issues relevant for multi-agent systems: reasoning with incomplete information, reasoning about knowledge and beliefs, and reasoning about games. Proofs as formal objects form the subject of Part II. Topics covered include: contributions on logical frameworks, linear logic, and different approaches (...) to formalized reasoning. Part III focuses on representations and formal methods in linguistic theory, addressing the areas of comparative and temporal expressions, modal subordination, and compositionality. (shrink)

ABSTRACTIn this research, we investigated whether appraisals of faces follow distinct rules of information integration under arousing versus non-arousing conditions. Support for this prediction was found in four experiments in which participants observed angry faces that were presented with a direct versus an averted gaze, on a red versus a grey background, and after performing a motor exercise versus no exercise. Under arousing conditions, participants’ appraisals of faces reflected summation whereas, under non-arousing conditions, appraisals did not reflect summation and could (...) instead be accounted for by three alternative rules of information integration based on averaging, mere exposure, or the number of strong stimuli.

In vol. 2 of Grundlagen der Mathematik Hilbert and Bernays carry out their undecid- ability proof of predicate logic basing it on their undecidability proof of the arithmeti- cal systemZ00. In this paper, the latter proof is reconstructed and summarized within a formal derivation schema. Formalizing the proof makes the presumed use of a meta language explicit by employing formal predicates as propositional functions, with ex- pressions as their arguments. In the final section of the paper, the proof is analyzed (...) critically by applying Wittgenstein’s view on meta language, which does not lead to a questioning of the assumptions on which the proof is based but of its presumed use of meta language. Finally, it will be argued that determining if it is the undecidability proof or Wittgenstein’s analysis of meta language that is right depends on whether a decision procedure for a predicate that undecidability proofs have seemingly proven undecidable can nonetheless be defined. Thus serious attempts to define a procedure for such a predicate should not be ruled out without studying them. (shrink)

Die philosophische Selbstergründung läuft als roter Faden durch das Gesamtwerk Wiebke Schraders. Aus der anthropologischen Auflösung der Gottesfrage folgte nicht die erwartete Aufwertung, sondern die Entwertung des Individuums mit katastrophalen politischen Konsequenzen. Gott als Problem ist systematisch nicht von der Selbstergründung der Vernunft, dem Fundament der Menschenwürde, zu trennen. Beide Problemkomplexe arbeitete W. Schrader in spekulativer Absicht denkgeschichtlich heraus. So erstreckt sich die Spannweite ihrer Studien u.a. von der Ideologiediskussion bei Mannheim, Marx und Comte über Kants Vernunftkritik, der Welt- und (...) Selbstgestaltung in der Philosophie der Renaissance zurück bis zu Augustinus und dem Problem eines höchsten Begriffs bei Anselm von Canterbury, Platon und Aristoteles. (shrink)

Instructions for authors need to be informative and regularly updated. We hypothesized that journals with a higher impact factor have more comprehensive IFA. The aim of the study was to examine whether IFA of journals indexed in the Journal Citation Reports 2013, “Medical Laboratory Technology” category, are written in accordance with the latest recommendations and whether the quality of instructions correlates with the journals’ IF. 6 out of 31 journals indexed in “Medical Laboratory Technology” category were excluded. The remaining 25 (...) journals were scored based on a set of 41 yes/no questions and divided into four groups by three authors independently. We tested the correlation between IF and total score and the difference between scores in separate question groups. The median total score was 26 [portion of positive answers 0.63 ]. There was no statistically significant correlation between a journal’s IF and the total score. IFA included recommendations concerning research ethics and manuscript preparation more extensively than recommendations concerning editorial policy and research integrity. Some policies were poorly described, for example: procedure for author’s appeal, editorial submissions, appointed body for research integrity issues. The IF of the “Medical Laboratory Technology” journals does not reflect a journals’ compliance to uniform standards. There is a need for improving editorial policies and the policies on research integrity. (shrink)

Rigidity does interesting philosophical work, with important consequences felt throughout metaphysics, epistemology, philosophy of mind, and so on. The authors’ aim in this article is to show that rigidity has yet another role to play, with surprising consequences for the problem of free will and determinism, for the phenomenon of rigidity has the upshot that some metaphysically necessary truths are up to us. The significance of this claim is shown in the context of influential arguments against free will. The authors (...) show that some virtually indisputable inference rules employed in formulations of the Consequence Argument, as well as in fatalistic arguments, fail with a variety of counter-examples. Along the way, the authors compare the present arguments to other, similar arguments made in recent years. (shrink)

For the newly trained Cognitive Behavioural Therapist, there are a wealth of challenges and difficulties faced as they try and apply their new found skills in the outside world. These might include the stresses of working in isolation, and finding it difficult to widen their scope or bounce ideas of other CBT therapists; or the need for practical advice on setting up group therapy; the possible conflicts betweens ethical practice and theory; trying to retain ones integrity as a therapist, while (...) maintaing a viable business practice.The Oxford Guide to Surviving CBT Practice is the one-stop resource for the newly trained therapist. It offers practical guidance on a range of issues and challenges faced by the therapist. Written by people with vast experience of training and practising CBT, it draws on real life situations to help the reader hone and develop their skills, adjust to life as a therapist, and maintain a successful and satisfying career whilst helping others.With thousands of new CBT therapists due to be trained over the coming years, this book will be a well thumbed and constant companion for all those starting life as a therapist - one they will want to have to hand at all times.

In this article I will address the issue of the embodiment of computing systems from the point of view distinctive of the so-called Unconventional Computation, focusing on the paradigm known as Morphological Computation. As a first step, I will contextualize Morphological Computation within the disciplinary field of Embodied Artificial Intelligence: broadly conceived, Embodied Artificial Intelligence may be characterized as embracing both conventional and unconventional approaches to the artificial emulation of natural intelligence. Morphological Computation stands out from other paradigms of unconventional (...) Embodied Artificial Intelligence in that it discloses a new, closer kind of connection between embodiment and computation. I will further my investigation by briefly reviewing the state-of-the-art in Morphological Computation: attention will be given to a very recent trend, whose core concept is that of “organic reconfigurability”. In this direction, as a final step, two advanced cases of study of organic or living morphological computers will be presented and discussed. The prospect is to shed some light on our title question: what progress has been made in understanding the embodiment of computing systems? (shrink)

In this article I will address the issue of the meaning of human-machine interaction as it is configured today in the light of substantial results achieved in the design and the manufacture of Artificial Intelligence (AI) systems. My starting point is a refined solution for meaningful AI recently suggested by Froese and Taguchi from the perspective of so-called augmented intelligence. Interpreted as a kind of human-machine interaction, augmented intelligence distinguishes itself by the fact that it merges the interacting poles into (...) a new hybrid entity. After having clarified the technical and the methodological background of my proposal, I will discuss a case of study of so-called bio-synthetic augmentation, where hybridisation overlaps with the cyborgisation of the human body.

Although learning from multiple representations has been shown to be effective in a variety of domains, little is known about the mechanisms by which it occurs. We analyzed log data on error-rate, hint-use, and time-spent obtained from two experiments with a Cognitive Tutor for fractions. The goal of the experiments was to compare learning from multiple graphical representations of fractions to learning from a single graphical representation. Finding that a simple statistical model did not fit data from either experiment, we (...) searched over all possible mediation models consistent with background knowledge, finding several that fit the data well. We also searched over alternative measures of student error-rate, hint-use, and time-spent to see if our data were better modeled with simple monotonic or u-shaped non-monotonic relationships. We found no evidence for non-monotonicity. No matter what measures we used, time-spent was irrelevant, and hint-use was only occasionally relevant. Although the total effect of multiple representations on learning was positive, they also had a negative effect on learning, mediated by a higher error-rate. Our evidence suggests that multiple representations increase error-rate, which in turn inhibits learning. The mechanisms by which multiple representations improve learning are as yet unmodeled.
