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)

Instead of essentializing and defining what CSR “is”, we analyze CSR as a political discourse in which different actors struggle to fill the empty shell of Corporate Social Responsibility (CSR) with a legitimate interpretation. In this paper we take the current debate on CSR in Austria as an example to demonstrate how this debate is shaped by changes in the greater socio-economic environment. We suggest that this debate might be paradigmatic for the development of CSR in the European/International context. We (...) argue that the debate and the political moves concerning an implicit or an explicit concept of CSR are rooted in a more fundamental question: the societal (re-)embedding or disembedding of companies.

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.

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.

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)

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.

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.

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)

"Pensar Europa en sus fronteras", como ya en 1992 proponían un grupo de filósofos de la Universidad de Estrasburgo -Denis Guénoun, Philippe Lacoue-Labarthe, Jean-Luc Nancy, Daniel Payot-, significa considerar qué es eso de la "geofilosofía de Europa" como una cuestión imprescindible que conlleva toda reflexión veraz en torno a la idea de Europa. El debate al que invitaron a una serie diversa de colegas y amigos, procedentes de diferentes naciones, planteaba la posibilidad misma de una identificación de Europa, así como (...) la profundidad, esto es, la misma violencia que esta posibilidad conlleva, como los hechos de la más reciente y rabiosa actualidad han confirmado una y otra vez desde aquellas fechas. La propuesta era todo menos fútil. En efecto, como es bien sabido y ellos mismos expresaron unos meses después, en julio de 1993, lo bien cierto es que ha habido terribles furores desencadenados y atroces desgarramientos tanto intra como extraeuropeos, que como mínimo nos urgen a pensar si el proyecto de lo que merece llamarse un 'mundo' puede o no puede confundirse con la exclusiva exportación de aquello que Europa habría inventado, producido e identificado. El futuro parece atenazado por dos figuras mórbidas, dos pesadillas simétricas, la mítica de un planeta homogéneo, como una gigantesca Europa que se extendiera por doquier, y la de una Europa recluida, encerrada en sus imprecisas e inciertas fronteras, una especie de barricadas o trincheras aislantes para que ella devorase en solitario el espejismo de su supuesto bienestar. Esta deplorable alternativa concita parte de nuestras responsabilidades, pues los escenarios del futuro se alimentan necesariamente de formas y de proposiciones de pensamiento, que vale la pena tratar de sopesar y de comprender. A este reto respondió la reflexión del profesor Bernhard Waldenfeis con una memorable intervención, publicada primero en francés de modo conciso y resumido, pero recogida luego en su versión definitiva en el capítulo 6 de su libro Topographie des Fremden, volumen primero de los cuatro de que se compone su magna obra Studien zur Phanomenologie des Fremden, publicada por la editorial Suhrkamp de Frankfurt del Meno en 1997. Queremos agradecer al autor y a la editorial su cortesía al permitir que publiquemos la traducción castellana de ese ensayo. "Thinking Europe at its limits", as proposed in 1992 by a group of philosophers from the University of Strasbourg -Denis Guénoun, Philippe Lacoue-Labarthe, Jean-Luc Nancy, Daniel Payot-, means considering what the "geo-philosophy of Europe" is as an essential question that encompasses all truthful reflection surrounding the idea of Europe. The debate, to which a diverse group of colleagues and friends from different nations were invited, advanced the very possibility of an identification of Europe, together with the profoundness, in other words the very violence that this possibility implies, as confirmed time and again since then by recent and highly topical events. The proposal was everything but futile. Indeed, as is well known and was confirmed by the group itself some months later in July 1993, what is certain is that a storm of terrible furores broke out and atrocious upheavals were expressed, both intra- and extra-European, that, if nothing else, urge us to consider whether the project of what deserves to be known as a "world"may or may not be confused with the exclusive exportation of what Europe has invented, produced and identified. The future appears to be in the grip of two morbid figures, two symmetrical nightmares: the myth of a homogeneous planet, like a gigantic Europe spreading everywhere; and a confined Europe, imprisoned in its imprecise and uncertain boundaries, a kind of isolating barricade or trenches enabling it to reclusively consume the illusion of its supposed welfare. This deplorable alternative incites part of our responsibilities, since the arenas of the future necessarily feed off the forms and propositions of thought, which are worthy of an attempt to weigh up and understand. Professor Bernhard Waldenfels responded to this challenge with a memorable intervention, a concise and summarised version of which was first published in French, the final version appearing in Chapter 6 of his book Topographie des Fremden, the first of four volumes that make up his great work Studien zur Phanomenologie des Fremden, published by Suhrkamp of Frankfurt del Meno in 1997. We wish to express our thanks to the author and the publishers for their kind permission to publish the Spanish translation of this essay. (shrink)

An ethical epoché is required to leave the terrain of a self-evident morality and question its origin. In particular, four fundamental motifs of the ethical dimension are identified: pathos, to be thematised as an alternative to the persistent activist unilateralism; response, which always involves body and soul; diastasis with its stumbles and subtractions; and finally coaffection, in which the social dimension of experience is announced. Ethical behaviour feeds on the magma of pathos, which in turn would be blind and directionless (...) without any ethos. (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.

Living corporeity is the intermediate element between nature and culture, which must be thought of as a reciprocal interconnection, since as corporeal beings we always move on a threshold. In the reflection of the bodily self, a doubling between the living body as a functioning subject and as a material object is revealed; after all, even one's own body sometimes takes on the features of a foreign body, as is the case in the experience of illness. In the technical instrument, (...) the body is prolonged and this highlights the connection between the technique of the thing and the technique of the self; however, despite the gradual autonomisation of the technical element from the living corporeity, there remains what escapes calculation and looms large in the subtraction of the alien.

One of the central logical ideas in Wittgenstein’sTractatus logico-philosophicusis the elimination of the identity sign in favor of the so-called “exclusive interpretation” of names and quantifiers requiring different names to refer to different objects and (roughly) different variables to take different values. In this paper, we examine a recent development of these ideas in papers by Kai Wehmeier. We diagnose two main problems of Wehmeier’s account, the first concerning the treatment of individual constants, the second concerning so-called “pseudo-propositions” (Scheinsätze) of (...) classical logic such as$a=a$or$a=b \wedge b=c \rightarrow a=c$. We argue that overcoming these problems requires two fairly drastic departures from Wehmeier’s account: (1) Not every formula of classical first-order logic will be translatable into asingleformula of Wittgenstein’s exclusive notation. Instead, there will often be a multiplicity of possible translations, revealing the original “inclusive” formulas to beambiguous. (2) Certain formulas of first-order logic such as$a=a$will not be translatable into Wittgenstein’s notation at all, being thereby revealed as nonsensical pseudo-propositions which should be excluded from a “correct” conceptual notation. We provide translation procedures from inclusive quantifier-free logic into the exclusive notation that take these modifications into account and define a notion of logical equivalence suitable for assessing these translations.

Theories of explanation seek to tell us what distinctively explanatory information is. The most ambitious ones, such as the DN-account, seek to tell us what an explanation is, tout court. Less ambitious ones, such as causal theories, restrict themselves to a particular domain of inquiry. The least ambitious theories constitute outright skepticism, holding that there is no reasonably unified phenomenon to give an account of. On these views, it is impossible to give any theories of explanation at all. I argue (...) that both the less ambitious and outright skeptical varieties are committed to a certain context-sensitivity of our explanatory discourse. And though this discourse is almost certainly context-sensitive in some respects, it does not exhibit the context-sensitivity less than fully ambitious theories are committed to. Therefore, all accounts that seek to restrict themselves in scope, including causal accounts of explanation, fail. (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. I argue that majority-based views face far more systematic counterexamples than has previously been supposed. They cannot account for generics about kinds with multiple characteristic properties, such as ‘elephants live in Africa and Asia.’ I then go (...) on to sketch an inquiry-based view. (shrink)

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)

In lieu of an abstract, here is a brief excerpt of the content:The Paradox of Education:A ConversationHumberto R. Maturana and Bernhard PoerksenResponsibility of the TeacherPoerksen: Immanuel Kant writes in his essay Über Pädagogik that the wide field of education is governed by a fundamental paradox. On the one hand, we want free and self-determined individuals to leave our schools; on the other, we impose a syllabus on the future individuals, force them to attend schools, punish their failures, and persecute (...) their noncompliance. There is, if we follow Kant, an inescapable relationship of tension between the goals and the means of educational efforts: They contradict each other. Would you agree?Maturana: No. Education, the commentary of an observer, is the process of transformation resulting from the co-existence with adults. We become the adults we have been living with. This means: If freedom and self-determined thinking are the goals of educational activity, then we have to live together in a way that is supported by the mutual respect for the autonomy of the other. In my view, the paradox formulated by Kant does not exist at all. The way of life, the manner of living together, shapes and transforms people. If you want to teach autonomy and reflection, you cannot use force as a method but must create an open space for communal reflection and action. There must be no contradiction between goals and means.Poerksen: Surely, there must also be constraints? It must be laid down when everybody has to be present, what the task is, who the teacher is, who has authority.Maturana: Compulsion will emerge if the teachers do not succeed in presenting their material in a thrilling way and in making school an attractive place of being together. Their failure will lead to force.Poerksen: The teacher is totally responsible for everything that may happen in school. Is this not an exaggerated claim?Maturana: No. If a teacher behaves respectfully, if he does not intimidate his pupils, if he listens, encourages cooperation and reflection, then a special form of interaction will emerge. The way of living practiced by the teacher, including the goals of teaching, will be the source of profitable learning for the pupils. This also implies that three questions and tasks must be sorted out cooperatively in education. First it seems necessary to me to debate the educational ideal to be chosen—what should the future adults be like when leaving the school one day? Should they be democratically minded and responsibly acting citizens? Or are they to be authoritarian and commandeering hierarchs, lords who feel superior to everyone else? It is then necessary to anchor a way of life in the school that permits acting and thinking according to that ideal. Finally, there is the essential task of preparing the teachers for their job in such a [End Page 25] way as to do justice to the desired goals—to enable them to live what they have to achieve.Poerksen: This would mean that teaching has nothing to do with the stepwise elimination of ignorance, as is commonly thought. The transmission of knowledge is secondary. The primary requirement is a way of life that corresponds with one's ideals, a particular form of living together, out of which the material topics will arise in due course.Maturana: Exactly. The children do not learn mathematics in school; they learn how to live together with a mathematics teacher. Perhaps they will one day carry on this enjoyable and exciting kind of being together independently—and become mathematics teachers or mathematicians themselves. Teachers do not simply transmit some content; they acquaint their pupils with a way of living. In the process, the rules of arithmetic, the laws of physics, or the grammar of a language will be acquired. My claim is: Pupils learn teachers.Poerksen: What about children who systematically refuse to cooperate? What is to be done with them? The classical answer is, of course: bad marks, relegation, exclusion from the winning circles.Maturana: The so-called difficult children about whom teachers keep complaining often only struggle to be seen and accepted, while the whole world expects them to behave in a calculable manner and to adapt to strange demands.

In the debate on peace ethics in Germany, it is constantly argued that the ‘doctrine of just war’ must be replaced by a ‘doctrine of just peace’. The criteriology of just war can at best be preserved within a doctrine of just peace. However, it is often overlooked that—although the word ‘peace’ may sound nicer than ‘war’—a doctrine of just peace is also fraught with great difficulties in terms of content. The concept of peace can be interpreted in different ways; (...) the concept of justice must even be differentiated if it is to have meaning at all. Ultimately, the two concepts point to a different understanding of tradition and historicity: while the doctrine of just war takes its criteria from the tradition, the idea of just peace attempts to draw conclusions for the present from drafts or blueprints of the future. However, since the drafts can turn out differently, new conflicts will arise precisely for this reason. Talk of ‘just peace’ might be more pleasing to the public, but does not necessarily have to be more restrictive in terms of violence. (shrink)

How different neural crest derivatives differentiate in distinct embryonic locations in the vertebrate embryo is an intriguing issue. Many attempts have been made to understand the underlying mechanism of specific pathway choices made by migrating neural crest cells. In this speculative review we suggest a new mechanism for the regulation of neural crest cell migration patterns in avian and mammalian embryos, based on recent progress in understanding the expression and activity of receptor tyrosine kinases during embryogenesis. Distinct subpopulations of crest‐derived (...) cells express specific receptor tyrosine kinases while residing in a migration staging area. We postulate that the differential expression of receptor tyrosine kinases by specific subpopulations of neural crest cells allows them to respond to localized growth factor ligand activity in the embryo. Thus, the migration pathway taken by neural crest subpopulations is determined by their receptor tyrosine kinase response to the differential localization of their cognate ligand. (shrink)

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)

The paper starts out with a discussion of the difference between mythology and feasible concepts in robotics. Based on a novel brain model and an appropriate formalism, a distinction is made between auto-reflection and hetero-reflection of the robot and self-reflection of its constructor. Whereas conscious robots are able to auto-reflect their mechanical behavior and hetero-reflect the behavior with regard to the environment, the capability of self-reflection must remain within the constructor of the robot. This limitation of the construction of conscious (...) robots is mainly brain-theoretically and philosophically founded. Finally, it is proposed that in addition to a second nature, human technology may succeed in creating a third nature embodied as a society of robots. (shrink)

Few would contest the fact that analytical philosophy has dominated philosophical practice in the English speaking world for about the last century. But dispute continues about both its origins and nature; whilst others question its value. Michael Dummett wholly embraced the analytical approach to philosophy, as he conceived of it. For him analytical philosophy marked itself off from its precursors and its alternatives, embodied in the Continental tradition, by taking the linguistic turn. And Frege was unequivocally the first philosopher to (...) take that auspicious turn, which ushered in a new method in philosophy. Henceforth philosophers were to approach the business of analyzing thought via the enterprise of analyzing language. So Dummett is presenting us with both a history lesson and a recommendation about how we ought to do philosophy. But is his reading of the history accurate? And is his conception of the nature of analytical philosophy viable? In order to reflect on these questions this collection brings together eight scholars who have made a serious business of reading Dummett. (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)

In the present note we give a direct deduction of the Axiom of Choice from the Maximal Ideal Theorem for commutative rings with unit.

This paper investigates the interaction between semantic theories for cp-laws (roughly, laws that hold “all things equal”) and metaphysical theories of kinds in the special sciences. Its central conclusion is that cp-laws concerning kinds behave differently from cp-laws concerning non-kinds: “ravens are black” which concerns the kind corvus corax, behaves differently from from “albino ravens are white” which concerns the non-kind grouping of albino ravens. I argue that this difference is in the first instance logical: the two sorts of cp-laws (...) give rise to different inferential patterns. I draw two further conclusions. The difference in logical behavior poses a severe problem for extant semantic theories of cp-laws, and: we cannot elucidate the distinction between kinds and non-kinds by suggesting that only kinds can appear in laws.

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)

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.

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.

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.

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.
