The issue of how basic sensory and temporal processing are related is still unresolved. We studied temporal processing, as assessed by simple visual reaction times (RT) and double-pulse resolution (DPR), in patients with partial vision loss after visual pathway lesions and investigated whether vision restoration training (VRT), a training program designed to improve light detection performance, would also affect temporal processing. Perimetric and campimetric visual field tests as well as maps of DPR thresholds and RT were acquired before and after (...) a 3 months training period with VRT. Patient performance was compared to that of age-matched healthy subjects. Intact visual field size increased during training. Averaged across the entire visual field, DPR remained constant while RT improved slightly. However, in transition zones between the blind and intact areas (areas of residual vision) where patients had shown between 20 and 80% of stimulus detection probability in pre-training visual field tests, both DPR and RT improved markedly. The magnitude of improvement depended on the defect depth (or degree of intactness) of the respective region at baseline. Inter-individual training outcome variability was very high, with some patients showing little change and others showing performance approaching that of healthy controls. Training-induced improvement of light detection in patients with visual field loss thus generalized to dynamic visual functions. The findings suggest that similar neural mechanisms may underlie the impairment and subsequent training-induced functional recovery of both light detection and temporal processing. (shrink)

We live in a technologically mediated lifeworld and culture. Technologies either magnify or amplify human experiences. They can change the ways we live. Technology has been woven into the social and cultural fabric of different cultures. German phenomenologist philosopher Bernhard Irrgang for than 2 decades engaging with the questions, what role does technology play in everyday human experience? How do technological artefacts affect people's existence and their relations with the world? And how do instruments, devices and apparatuses produce and (...) transform human knowledge? Along with Albert Borgmann, Larry Hickman, Don Ihde, Carl Mitcham, Hans Poser, Peter-Paul Verbeek, Walther Zimmerli, contemporary German philosopher of technology Bernhard Irrgang provides a useful vocabulary for understanding the ways we relate to technology and to the world through technologies in different cultures.

There are many things—call them ‘experts’—that you should defer to in forming your opinions. The trouble is, many experts are modest: they’re less than certain that they are worthy of deference. When this happens, the standard theories of deference break down: the most popular (“Reflection”-style) principles collapse to inconsistency, while their most popular (“New-Reflection”-style) variants allow you to defer to someone while regarding them as an anti-expert. We propose a middle way: deferring to someone involves preferring to make any decision (...) using their opinions instead of your own. In a slogan, deferring opinions is deferring decisions. Generalizing the proposal of Dorst (2020a), we first formulate a new principle that shows exactly how your opinions must relate to an expert’s for this to be so. We then build off the results of Levinstein (2019) and Campbell-Moore (2020) to show that this principle is also equivalent to the constraint that you must always expect the expert’s estimates to be more accurate than your own. Finally, we characterize the conditions an expert’s opinions must meet to be worthy of deference in this sense, showing how they sit naturally between the too-strong constraints of Reflection and the too-weak constraints of New Reflection.

Frames are a concept in knowledge representation that explains how the receiver, using background information, completes the information conveyed by the sender. This concept is used in different disciplines, most notably in cognitive linguistics and artificial intelligence. This paper argues that frames can serve as the basis for describing mathematical proofs. The usefulness of the concept is illustrated by giving a partial formalisation of proof frames, specifically focusing on induction proofs, and relevant parts of the mathematical theory within which the (...) proofs are conducted; for the latter, we look at natural numbers and trees specifically.

This article explores the implications of Bernhard Waldenfels’s responsive phenomenology for the discipline of cultural anthropology or ethnology, insofar as it understands itself as the “science of the culturally Other”. It discusses Waldenfels’s own engagement with ethnology and shows the compatibility of his approach with discussions within the discipline. The intertwining of ownness and alienness that is central to Waldenfels’s account of experience is applied to the problem of culture in ethnology. This leads to an acknowledgement of a domain (...) between cultures, a genuine interculturality, as the fundamental field of ethnological research, which, however, can only be addressed through indirect forms of representation. Such forms are identified in the practice of ethnographic citation, and through a reinterpretation of Horace Miner’s classical satire “Body Ritual among the Nacirema”, thus demonstrating the possibility of a prospective “responsive ethnology”.

Bernhard Nickel presents a theory of generic sentences and the kind-directed modes of thought they express. The theory closely integrates compositional semantics with metaphysics to solve the problem that generics pose: what do generics mean? Generic sentences are extremely simple, yet if there are patterns to be discerned in terms of which are true and which are false, these patterns are subtle and complex. Ravens are black, and lions have manes: statistical measures cannot do justice to the facts, but (...) what else is there that has a hope of giving us insight into what we are capturing across so many domains? Nickel argues that generics are the top of a fundamentally explanatory iceberg, and that this explanatory framework is deeply intertwined with the semantics of the language we use to express them. In providing an integrated semantic and metaphysical theory of generics, he aims to solve old puzzles and draw attention to new phenomena. (shrink)

Traditional approaches to human information processing tend to deal with perception and action planning in isolation, so that an adequate account of the perception-action interface is still missing. On the perceptual side, the dominant cognitive view largely underestimates, and thus fails to account for, the impact of action-related processes on both the processing of perceptual information and on perceptual learning. On the action side, most approaches conceive of action planning as a mere continuation of stimulus processing, thus failing to account (...) for the goal-directedness of even the simplest reaction in an experimental task. We propose a new framework for a more adequate theoretical treatment of perception and action planning, in which perceptual contents and action plans are coded in a common representational medium by feature codes with distal reference. Perceived events (perceptions) and to-be-produced events (actions) are equally represented by integrated, task-tuned networks of feature codes – cognitive structures we call event codes. We give an overview of evidence from a wide variety of empirical domains, such as spatial stimulus-response compatibility, sensorimotor synchronization, and ideomotor action, showing that our main assumptions are well supported by the data. Key Words: action planning; binding; common coding; event coding; feature integration; perception; perception-action interface. (shrink)

Wittgenstein’s Whewell’s Court Lectures contains previously unpublished notes from lectures given by Ludwig Wittgenstein between 1938 and 1941. The volume offers new insight into the development of Wittgenstein’s thought and includes some of the finest examples of Wittgenstein’s lectures in regard to both content and reliability.

Good’s theorem is the apparent platitude that it is always rational to ‘look before you leap’: to gather information before making a decision when doing so is free. We argue that Good’s theorem is not platitudinous and may be false. And we argue that the correct advice is rather to ‘make your act depend on the answer to a question’. Looking before you leap is rational when, but only when, it is a way to do this.

This book suggests that to know how Wittgenstein’s post-Tractarian philosophy could have developed from the work of Kant is to know how they relate to each other. The development from the latter to the former is invoked heuristically as a means of interpretation, rather than a historical process or direct influence of Kant on Wittgenstein. Ritter provides a detailed treatment of transcendentalism, idealism, and the concept of illusion in Kant’s and Wittgenstein’s criticism of metaphysics. Notably, it is through the conceptions (...) of transcendentalism and idealism that Wittgenstein’s philosophy can be viewed as a transformation of Kantianism. This transformation involves a deflationary conception of transcendental idealism along with the abandonment of both the idea that there can be a priori 'conditions of possibility' logically detachable from what they condition, and the appeal to an original ‘constitution’ of experience. -/- The closeness of Kant and post-Tractarian Wittgenstein does not exist between their arguments or the views they upheld, but rather in their affiliation against forms of transcendental realism and empirical idealism. Ritter skilfully challenges several dominant views on the relationship of Kant and Wittgenstein, especially concerning the cogency of Wittgenstein-inspired criticism focusing on the role of language in the first Critique, and Kant's alleged commitment to a representationalist conception of empirical intuition.

The article is dedicated to the application questions of a case study method known as casuistry. In its long tradition, it focuses on an influential variant of the early modern period and reconstructs its functionality. In the course of reading recent receptions, it is noted that some studies speak of a “casuistic revival” in moral case deliberation in health care. As a result of this revival, casuistry has been modified in such a way that it guides case discussions in practice (...) with the help of a tripartite methodology. However, as it turns out, casuistry, a case comparison method of ethical judgement based on reasoning logic, is less suitable for moral case deliberations in direct patient care. This stems from the fact that casuistry is a detailed procedure of ethical learning beneficial to institutionalized ethics committees or similar forms of ethics consultation in health care. (shrink)

A model of an intentional self-observing system is proposed based on the structure and functions of astrocyte-synapse interactions in tripartite synapses. Astrocyte-synapse interactions are cyclically organized and operate via feedforward and feedback mechanisms, formally described by proemial counting. Synaptic, extrasynaptic and astrocyte receptors are interpreted as places with the same or different quality of information processing described by the combinatorics of tritograms. It is hypothesized that receptors on the astrocytic membrane may embody intentional programs that select corresponding synaptic and extrasynaptic (...) receptors for the formation of receptor-receptor complexes. Basically, the act of self-observation is generated if the actual environmental information is appropriate to the intended observation processed by receptor-receptor complexes. This mechanism is implemented for a robot brain enabling the robot to experience environmental information as “its own”. It is suggested that this mechanism enables the robot to generate matches and mismatches between intended observations and the observations in the environment, based on the cyclic organization of the mechanism. In exploring an unknown environment the robot may stepwise construct an observation space, stored in memory, commanded and controlled by the intentional self-observing system. Finally, the role of self-observation in machine consciousness is shortly discussed. (shrink)

Había tiempos en los que como fenomenólogo uno era visto de forma muy crítica y también compasiva cuando le atribuía a imágenes y signos algo así como una presencia encarnada. Ahora nos encontramos más bien con un exceso de oferta de presencia, inmediatez, contacto y cercanía. Sin embargo, algo de esto parece ser una reversión con la que se intenta sobrecompensar deficiencias anteriores. También en la filosofía, de cuando en cuando, se da un afán excesivo, como se encuentra en los (...) recién convertidos. Pero dejemos hablar a las cosas mismas. Con este fin me limito a señalar en forma de resumen algunos puntos tanto relevantes como controvertidos que conciernen en su conjunto al lugar de las imágenes en la experiencia y que adquieren un tono particular a través del contraste entre eidos y pathos2.

Many approaches to the semantics of generic sentences posit an unpronounced quantifier gen. However, while overt quantifiers are conservative, gen does not seem to be. A quantifier Q is conservative iff instances of the following schemas are equivalent: Q As are F and Q As are As that are F. All ravens are black is obviously equivalent to All ravens are ravens that are black, yet ravens are black is not equivalent to ravens are ravens that are black. This may (...) cast doubt on theviability of quantificational analyses of generics. This paper proposes a theory of why such “conservativity” generics are problematic that is compatible with the conservativity of gen and also accounts for perennially troublesome examples such as books are paperbacks and bees are workers.

The present paper reports the results of a vignette- and questionnaire-based research project investigating the influence of Moral Intensity (MI) on decision making in a New Zealand business context. The use of a relatively sensitive research design yielded results showing that – in contrast to previous research – objective manipulations, as well as subjective perceptions, of three of the six MI components were of particular importance in accounting for a comparatively large proportion of the variation in four outcome variables. There (...) were no interactions of appreciable magnitude between MI components, or variations across scenarios. Also, no support was found for a reliable multi-dimensional structure of perceptions of Moral Intensity. Implications of the findings are discussed. (shrink)

Both Brandom and Wittgenstein see meaning and content as emerging from normative social practices. Wittgenstein says little about the constitution of such norms, other than that they are exhibited in practitioners’ judgements of correctness. In addition, they appear already to be content involving, since the moves whose correctness is in question are moves such as asserting that such and such. In contrast, Brandom says a good deal about the constitution of the norms and promises a reductive programme. The norms are (...) essentially inferential and are instituted in the social practice of attributing commitments and entitlements. In particular, we are urged to see the norm-bound move of assertion as capable of being understood in terms of the normative statuses of commitments and entitlements. Jeremy Wanderer calls this Brandom’s bold conjecture. In this paper I use Wittgenstein’s thinking about normativity to reflect on the defensibility of Brandom’s bold conjecture. (shrink)

Dorr et al. present a case that poses a challenge for a number of plausible principles about knowledge and objective chance. Implicit in their discussion is an interesting new argument against KK, the principle that anyone who knows p is in a position to know that they know p. We bring out this argument, and investigate possible responses for defenders of KK, establishing new connections between KK and various knowledge-chance principles.

"Bernard Groethuysen (1880-1946), philosophe d'origine allemande, partage, dès 1904, sa vie entre Berlin et Paris où il étudie la Révolution française et rencontre, grâce à Bergson, Alix Guillain (1876-1951), traductrice et journaliste à L'Humanité. Vivant avec leurs compagnes dans le phalanstère de la rue Campagne-Première, Groethuysen et Paulhan, devenus amis, oeuvrent à partir de 1920 à La Nouvelle Revue francaise, dont ce dernier prend la direction cinq ans plus tard : ils font découvrir Hôlderlin, Kassner, Kafka, Büchner, Musil... En 1927, (...) ils inaugurent leur collection "Bibliothèque des Idées" par l'essai majeur de Groethuysen, Origines de l'esprit bourgeois en France, "notre premier enfant", écrit-il à Paulhan. Dans son ultime lettre d'Allemagne, de 1931, il s'inquiète : "L'Histoire devrait nous donner des vacances. On en profiterait pour reprendre la vie." En août 1932, devant l'essor du nazisme, Groethuysen s'exile en France. Quant à Paulhan, le Front populaire le voit s'engager aux côtés de Jean Longuet, maire socialiste de Châtenay-Malabry. Arrive la guerre : Germaine et Jean Paulhan quittent leur maison, leur jardin, leurs animaux, dont Alix Guillain et Groethuysen, naturalisé en 1938, prennent soin. Après la défaite de l'Allemagne, le philosophe rêve encore d'utopie, mais il meurt le 17 septembre 1946. Les travaux de Groethuysen m'intéressaient, il s'intéressait aux miens", confiera Paulhan à Ponge. Ce volume prouve leur affectueuse amitié, fondée sur le travail en commun pour la NRF. Mais c'est également un document sur les réseaux intellectuels et politiques de l'entre-deux-guerres: Maria Van Rysselberghe et les amis de Gide, la princesse de Bassiano et la revue Commerce, Paul Desjardins et les Décades de Pontigny, Henry Church et la revue Mesures, Alix Guillain et le Parti communiste, Aline Mayrisch et le groupe de Colpach... "Je n'ai pas connu d'autre homme, écrira Paulhan, pour qui une idée, fût-elle évidemment fausse ou absurde, dès l'instant qu'un homme l'avait inventée, eût un tel prix. Il disait: "C'est une idée" d'un ton de gourmet. C'est qu'il pensait que la vérité ayant été une fois dans la suite des temps atteinte (par Hegel et - pour ce qui concernait son application au monde moderne - par Marx), il ne nous restait qu'à former des idées - plus ou moins agréables, curieuses, attendrissantes de faiblesse."

Dr. Northoff's comprehensive comparison of clinical symptoms and neurobiological findings in catatonia with that of Parkinson's disease through integration of various levels of investigation, from neurochemistry up to the subjective experience, is a good example of the new strategies we need to improve our understanding of psychiatric disorders. His multimodal approach, leading to the hypothesis that different pathophysiologies of transcortical “horizontal modulation” and “bottom-up/top-down” – orbitofrontal/basal ganglia – “vertical modulations,” may explain many clinical aspects of catatonia and Parkinson's disease, and (...) thereby fills an important gap in current theories of psychomotor syndromes. However, to analyze more specifically the pathophysiology of catatonia, comparison not only with Parkinson's disease, but also with schizophrenia and anxiety disorders would be helpful. As long as the pathohistological and molecular basis of catatonic syndromes is unknown, theories based mainly on functional considerations remain preliminary. (shrink)

This article deals with developments of Shinto in the seventeenth century, focussing on the school of Yoshikawa Shinto. It is presented as an example of the coalition between Shinto and Neo-Confucianism intellectuals typical for that time. Pointing out the medieval predecessors of this coalition, the article argues that the theological ideas of Yoshikawa Shinto were much more indebted to medieval Shinto than is generally assumed. This is demonstrated by a doctrinal comparison as well as by a historiographical sketch of the (...) relations between Yoshikawa Shinto and Yoshida Shinto. Both schools regarded themselves as legitimate representatives of Japan's original Way of the kami. The article examines the internaljustifications of these claims as well as their acknowledgments by thepolitical authorities. (shrink)

In this paper we bring together results from a series of previous papers to prove the constructive version of the Gelfand duality theorem in any Grothendieck topos , obtaining a dual equivalence between the category of commutative C*-algebras and the category of compact, completely regular locales in the topos.

Religions commonly are taken to provide general orientation in leading one's life. We develop here the idea that religions also may have a much more concrete guidance function in providing systematic decision biases in the face of cognitive-control dilemmas. In particular, we assume that the selective reward that religious belief systems provide for rule-conforming behavior induces systematic biases in cognitive-control parameters that are functional in producing the wanted behavior. These biases serve as default values under uncertainty and affect performance in (...) any task that shares cognitive-control operations with the religiously motivated rule-conforming behavior the biases were originally developed for. Such biases therefore can be unraveled and objectified by means of rather simple tasks that are relatively well understood with regard to the cognitive mechanisms they draw on. (shrink)

In this article, I apply a structural-phenomenological conception of experience and self to the anthropological theorizing of spirit possession. In particular, I argue that a phenomenology of the alien, as elaborated by the philosopher Bernhard Waldenfels, allows for a more differentiated understanding of possession phenomena. Following a characterization of alienness—in conceptual distinction from the more common term “otherness”—as a dimension that necessarily eludes experience, I describe spirit possession as a cultural technology to appropriate the experiential alien by transforming it (...) into the symbolic other. I discuss this relation to the alien in thematic areas central to the anthropology of possession: illness and therapy, symbolism and naming, embodiment and self. (shrink)

I contrast two approaches to the interpretation of generics such as `ravens are black:' majority-based views, on which they are about what is the case most of the time, and inquiry-based views, on which they are about a feature we focus on in inquiry---an inductive target. I argue that while majority-based views are preferable based on the most basic data about generics, only inquiry-based views can account for a systematic class of sentences: generics with logically complex predicates, such as `cats (...) are black, white, and ginger.' Thus, inquiry-based views should carry the day. I then go on to sketch a theory of inductive targets. (shrink)

ZusammenfassungAktuelle Positionspapiere wie das der Sektion Ethik der Deutschen Interdisziplinären Vereinigung für Intensiv- und Notfallmedizin „Therapiezieländerung und Therapiebegrenzung in der Intensivmedizin“, die „Münchner Leitlinie zu Entscheidungen am Lebensende“ und die Erlanger „Empfehlungen zur Behandlungsbegrenzung auf Intensivstationen“ konzentrieren sich auf die Begründung und Erstellung praxistauglicher Entscheidungspfade. Dabei bleibt kaum Raum für die Darlegung der moraltheoretischen Grundlagen zur formalen Handlungsbewertung einer Indikationsstellung am Lebensende. Der Beitrag will anhand einer intensivmedizinischen Entscheidungssituation zeigen, dass im Falle einer Therapiezieländerung aus Indikationsgründen eine aristotelische Argumentation zentrale (...) Bedeutung erhält. Sie besteht in der begründeten Festlegung eines realistisch erreichbaren Ziels und des dahin führenden Therapiepfades. Klinische Ethikberatung, so das Resultat, kann demnach nicht nur die Bedeutung von inhaltlichen Prinzipien unterstreichen, sondern muss auch ihre Kenntnis der formalen Handlungsbewertung zur Geltung bringen.

Contemporary philosophers and scientists have done much to expand our understanding of the structure and neural mechanisms of joint action. But the phenomenology of joint action has only recently become a live topic for research.One method of clarifying what is unique about the phenomenology of joint action is by considering the alternative perspective of agents subsumed in group action. By group action we mean instances of individual agents acting while embedded within a group agent, instead of with individual coordination. Paradigm (...) examples are educational bureaucracies, corporations, and nation states. There is a phenomenological difference between agents whose actions are subsumed within a group action as compared to agents who act jointly. Attending to this difference clarifies what is phenomenologically distinctive about joint action.Appealing to an Aristotelian account of agency and to the metaphysical concept of weak emergence, we argue that what makes paradigmatic group action distinctive is the relative inaccessibility, un-revisability, and evaluative simplicity of the group agent’s goal from the perspective of individual agents. This suggests that a distinctive feature of joint agency is the maintenance of a greater sense of individual agency. Put simply, joint agency is often experienced as an enhancement of the individuals’ agency precisely because our paradigmatic agential powers are extended intersubjectively as we act together. In contrast, group agency often involves a loss of the sense of agency, precisely because it is the emergent group agent that maintains the agential powers. (shrink)

Ceteris Paribus (cp-)laws may be said to hold only “other things equal,” signaling that their truth is compatible with a range of exceptions. This paper provides a new semantic account for some of the sentences used to state cp-laws. Its core approach is to relate these laws to natural language on the one hand — by arguing that cp-laws are most naturally expressed with generics — and to natural kinds on the other — by arguing that the semantics of generics (...) in the context of the special sciences are best spelled out by appeal to natural kinds. The paper then goes on to draw on these semantics in order to illuminate several problems raised by cp-laws, some familiar, some new. (shrink)

The specter of the ‘group mind’ or ‘collective subject’ plays a crucial and fateful role in the current debate on collective intentionality. Fear of the group mind is one important reason why philosophers of collective intentionality resort to individualism. It is argued here that this measure taken against the group mind is as unnecessary as it is detrimental to our understanding of what it means to share an intention. A non-individualistic concept of shared intentionality does not necessarily have to get (...) stuck with some collectivist super-agent. Rather, the specter of the group mind arises from a deep-seated ‘Cartesian’ preconception concerning intentionality, which we should try to overcome. (shrink)
