In people with chronic low back pain, maladaptive structural and functional changes on a cortical level have been identified. On a functional level, somatosensory cortical excitability has been shown to be reduced in chronic pain conditions, resulting in cortical disinhibition. The occurrence of structural and/or functional maladaptive cortical changes in people with CLBP could play a role in maintaining the pain. There is currently no measurement protocol for cortical excitability that employs stimulation directly to the lower back. We developed a (...) protocol for the measurement of single pulse somatosensory evoked potential waveforms and paired-pulse behavior generated from sensory nerves of the lower back and quantified its test–retest reliability in a sample of 30 healthy individuals to gain insights into the normal variability of cortical responses, which could then be compared to results from people with CLBP. We investigated cortical excitability by measuring SEPs and PPB. PPB was defined as the ratio of the amplitude of the second cortical response divided by the first cortical response. A2s was determined by subtracting the response to single-pulse stimuli from the paired pulse stimuli response to account for linear superposition effects. The test–retest reliability of the protocol was very poor with no evidence of systematic bias but a high amount of random variability between sessions. There was no significant difference in the right side PPB for session 1 and session 2 ; mean session difference [ = −0.44 ; t = −1.17, p = 0.26]. The ICC3.1 for the outlier-removed right side PPB were 0.19 and 0.43 for left side PPB. This finding potentially has wider implications for PPB protocols. If these findings were replicated in other groups and other nerves, it would question the validity of this measure more generally. However, these findings are restricted to healthy people and sensory nerves of the lower back and may not be generalizable. (shrink)

For Descartes, knowledge exists as ideas in the mind that represent the world. In a radical critique, Hubert Dreyfus and Charles Taylor argue that knowledge consists of much more than the representations we formulate in our minds. They affirm our direct contact with reality—both the physical and the social world—and our shared understanding of it.

Metabolic dysfunction is a ubiquitous underlying feature of many neurological conditions including acute traumatic brain injuries and chronic neurodegenerative conditions. A central problem in neurological patients, in particular those with traumatic brain injuries, is an impairment in the utilization of glucose, which is the predominant metabolic substrate in a normally functioning brain. In such patients, alternative substrates including ketone bodies and lactate become important metabolic candidates for maintaining brain function. While the potential neuroprotective benefits of ketosis have been recognized for (...) up to almost a century, the majority of work has focused on the use of ketogenic diets to induce such a state, which is inappropriate in cases of acute disease due to the prolonged periods of time (i.e., weeks to months) required for the effects of a ketogenic diet to be seen. The following review seeks to explore the neuroprotective effects of exogenous ketone and lactate preparations, which have more recently become commercially available and are able to induce a deep ketogenic response in a fraction of the time. The rapid response of exogenous preparations makes their use as a therapeutic adjunct more feasible from a clinical perspective in both acute and chronic neurological conditions. Potentially, their ability to globally moderate long-term, occult brain dysfunction may also be relevant in reducing lifetime risks of certain neurodegenerative conditions. In particular, this review explores the association between traumatic brain injury and contusion-related dementia, assessing metabolic parallels and highlighting the potential role of exogenous ketone and lactate therapies.

A los efectos de mostrar el compromiso de Utopía de Moro con el ideal republicano de una civitas libera se siguen en este trabajo tres pasos o momentos. Tras unas breves, pero necesarias consideraciones terminológicas acerca de los dos principales sentidos de “república” a comienzos del siglo XVI, se desarrolla la concepción acerca de la naturaleza y legitimidad del poder defendida en la obra. Luego se analiza cómo dicho principio se traduce en las instituciones y prácticas de la comunidad utopiense. (...) Y finalmente se intenta dar cuenta de cómo dichas instituciones y prácticas cristalizan en aquel modelo político (típico del republicanismo renacentista) llamado “régimen mixto”, que combina la monarquía, la democracia y la aristocracia. Ahora bien, la expresión concreta de este último aspecto en la vida de Utopía da lugar a una interesante tensión interna. En efecto, por una parte, produce una significativa restricción de la libertad política al reconocer derechos desiguales al “pueblo” (que solo elige, pero no puede ser elegido para las principales magistraturas) respecto del estamento intelectual (que es el único que puede ser elegido para las mismas). Pero, al mismo tiempo, si tenemos en cuenta que la pertenencia a dicho estamento no depende en absoluto de la riqueza (puesto que en Utopía no hay propiedad privada, sino propiedad común), de aquí podemos inferir que se ha comenzado a pensar de modo decidido y disruptivo la igualdad material como condición necesaria de la auténtica libertad política.

It has often been argued that Thomas More’s Utopia is fundamentally concerned with outlining and theoretically justifying an ideal model of society and not with determining what would be the practical steps required for its establishment in the real world. Even if we were to accept this widespread interpretation, I consider that it is possible to recognize in the text indications that suggest two different and even opposing paths along which the political construction of Utopia could take place. The first, (...) and strictly speaking, the only one that the work is trying to put forward, is individual, elitist, coercive, and top-down. The second that, for its part, seems to be presented rather with the intention of preventing it from coming to fruition is hence, on the contrary, collective, popular, insurrectionary and from below. The present article tries, first, to show how and through what arguments these two models of action are presented in More’s work, taking note, in addition, of the important difficulties involved in the one which it intends to propose. After this, two historical realizations immediately after Utopia was published that illustrate them are developed. Finally, the present article tries to establish what relationship these two paths have with each other according to the work’s approach and, also, suggest what alternative relationship they could maintain if a different point of view was attempted.

Migrant farmworkers dominate the horticultural workforce in many parts of the Minority (developed) World. The ‘manual’ work that they do—picking and packing fruits and vegetables, and pruning vines and trees—is widely designated unskilled. In policy, media, academic, activist and everyday discourses, hired farm work is framed as something anybody can do. We interrogate this notion with empirical evidence from the Sunraysia horticultural region of Australia. The region’s grape and almond farms depend heavily on migrant workers. By-and-large, the farmers and farmworkers (...) we spoke to pushed back against the unskilled tag. They asserted that farmworkers acquire knowledge and skills over time and that experienced farmworkers are valuable—their value being brought into sharp relief against accounts of inexperienced farmworkers’ errors. Our interviewees provided rich insights into farmworkers’ engagements with crops and the intricacies of picking and pruning well. Far from being bereft of knowledge and skills, they recognised that experienced farmworkers bring benefits. They improve productivity, product quality and ultimately profits. This is especially so when open communication channels exist across the farm hierarchy, when experienced farmworkers’ insights are taken seriously by their employers. Our research is informed by organisational studies literature and scholarship on craft/making. Like factory floor workers and artisans, experienced farmworkers bring accumulated knowledge and skills to their work, gained through repeat performance. They reflect on and adjust their activities in dialogue with their materials and the environment. Experienced farmworkers demonstrate care, dexterity and judgement. They are not unskilled, and they are more than labouring bodies. (shrink)

For fifty years Hubert Dreyfus has done pioneering work which brings phenomenology and existentialism to bear on the philosophical and scientific study of the mind. This is a selection of his most influential essays, developing his critique of the representational model of the mind in analytical philosophy of mind and mainstream cognitive science.

This volume presents a selection of Hubert Dreyfus's pioneering work in bringing phenomenology and existentialism to bear on the philosophical and scientific study of the mind. Each of the thirteen essays interprets, develops, and extends the insights of his predecessors working in the European philosophical tradition. One of Dreyfus' central contributions to reading the historical canon of philosophy comes from his recognition that great philosophers help us to understand the -background practices- of a culture - the practices that shape (...) and embody our most basic understanding of ourselves and the things and situations we encounter in our world. Background practices are all too often overlooked completely, or else their importance is misunderstood. Each chapter in this volume shows in one way or another how a broad range of philosophical topics can only be properly understood when we recognize how they are grounded in the background practices that shape our lives and give meaning to our activities, our tasks, our normative commitments, our aims and our goals.

Structurally, cognitive and biological evolution are highly similar. Random variation and constant but blind selection drive evolution within biology as well as within cognition. However, evolution of cognitive programs, and in particular of grammar systems, is not a subclass of biological evolution but a domain of its own. The abstract evolutionary principles, however, are akin in cognitive and biological evolution. In other words, insights gained in the biological domain can be cautiously applied to the cognitive domain. This paper claims that (...) the cognitively encapsulated, i.e. consciously inaccessible, aspects of grammars as cognitively represented systems, that is, the procedural and structural parts of grammars, are subject to, and results of, Darwinian evolution, applying to a domain-specific cognitive program. Other, consciously accessible aspects of language do not fall under Darwinian evolutionary principles, but are mostly instances of social changes. (shrink)

Ethics, in the sense of a recognized branch of inquiry, reputedly began with Socrates and the Sophists, at least for the western world. Ethics, understood as a set of moral standards, traditionalized by maxims and admonitions, has existed in human cultures from so early a time that it would be hazardous indeed to conjecture the date of its probable origin. The "Hopi Ethics" which Mr. Brandt has studied is obviously that of this second sense, whereas his own study, at least (...) insofar as it is a "theoretical analysis" and goes beyond mere description, is "ethics" in the first sense. That the Hopi Indians were somewhat astonished and perplexed by Mr. Brandt's line of inquiry is indicated by some of their quoted remarks, such as their mention of the "hard questions" being put to them, and their amazement at the suggestion of the possibility that "there is no right answer to ethical questions." One gathers, thus, that while the problem of ethical relativism was of high concern to Mr. Brandt, such an idea was nigh unthinkable to the Hopi. (shrink)

Celem artykułu jest pogłębiona analiza przyczyn i konsekwencji rozdwojenia sejmiku wiszeńskiego w 1597 r. z naciskiem na relacje polityczno-społeczne obejmujące teren dawnego województwa ruskiego oraz głównych politycznych aktorów zdarzeń: Stanisława Stadnickiego z Łańcuta, Stanisława Żółkiewskiego i Jana Zamoyskiego. Pomimo stosunkowo obfitego materiału źródłowego w postaci listów, protestacji i sejmowych diariuszy jedyna poważna próba zbadania tego tematu podjęta przez Jana Rzońcę okazała się dalece niewystarczająca, zawężając temat rozbicia sejmiku jedynie do obszaru wpływu na późniejsze obrady sejmu oraz ogólną kondycję państwa. Przeprowadzona (...) w artykule krytyczna analiza zachowanych źródeł pozwoliła w dużym stopniu zrekonstruować obrady tytułowego sejmiku, ustalić dokładne przyczyny jego rozbicia oraz powiązać zaszłe na nim zdarzenia z politycznym przesileniem, do którego doszło w województwie ruskim pod koniec roku 1597 w postaci lokalnego sojuszu Jana Zamoyskiego ze Stanisławem Stadnickim z Łańcuta. Poznanie kulis zawarcia powyższego porozumienia oraz powodów jego fiaska pozwoliło natomiast lepiej zrozumieć mechanizmy funkcjonowania stronnictwa kanclerskiego pod koniec XVI w. i stanu, w jakim się wówczas znalazło. W artykule podjęta została ponadto próba rozwikłania problemu uczestnictwa w sejmiku żołnierzy kwarcianych/prywatnych oraz zbadania ich rzeczywistego wpływu na obrady sejmiku w Wiszni. Bezrefleksyjnie przyjmowana do tej pory teoria personalnie obarczająca winą za rozbicie sejmiku hetmana polnego Stanisława Żółkiewskiego wydaje się co najmniej przesadzona, zupełnie pomijając własnowolność służących w wojsku żołnierzy oraz przysługujące im jako szlachcie prawa do uczestnictwa w życiu publicznym Rzeczypospolitej.

The article examines one quodlibet of thomas of sutton (c. 1287 a. d.) and compares it with a quodlibet of william of ockham (d. 1349 a. d.). both attack the position of henry of ghent on the distinction between essence and existence. and both reach opposite conclusions. thomas of sutton argued that the distinction is a real one, while ockham saw it only as nominal and connotative. the opposing views stem from different epistemologies and different metaphysics.

A remarkable turnaround by a leader with a remarkable philosophy: Find your noble purpose. Put people at the center. Unleash human magic. "It was Fall in Minnesota. It was getting cold and we were supposed to die." This is how Hubert Joly describes the early, dark days as CEO of Best Buy, a job most thought he was crazy to accept. Amazon was tearing a disruptive path through retail, but in the face of that existential threat Joly did something (...) remarkable: he saved Best Buy and remade it into a thriving company rated as one of the most desirable businesses to work for. Having recently stepped down as Chairman and CEO, Joly is ready to share the leadership principles that underpinned the resurgence of Best Buy and that he believes are at the heart of business: pursue a noble purpose, put people at the center, unleash human magic, and treat profit as an outcome. There was a time when many would call this a soft philosophy. But times are changing. Best Buy and 180 other companies signed the momentous Business Roundtable statement in support of stakeholder capitalism. The Covid-19 pandemic further pushed many businesses to lead from a place of purpose and with humanity. The changes underway are not a revolt, but a revolution. And Joly provides concrete advice on how to implement principles that can serve as beacons for the next era of capitalism. Joly himself was transformed from a hard-charging, deeply analytical McKinsey consultant to a leader who believes in what he calls human magic. He will share how so much of what he initially learned about management is either dated, incomplete, or simply wrong-including how to turn around a business, develop and implement a strategy, mobilize an organization, and what it takes to be a great leader. The leadership principles Joly lays out worked at Best Buy. They can also contribute to the necessary re-foundation of business and capitalism around purpose and humanity. (shrink)

_Internet_ is een van de eerste boeken waarin het filosofische inzicht -van Plato tot Kierkegaard - betrokken wordt op het debat over de mogelijkheden en onmogelijkheden van het internet. Dreyfus laat zien dat de onstoffelijke, 'vrij zwevende' websurfer zijn oorsprong vindt in Descartes' scheiding van geest en lichaam, en hoe Kierkegaards inzichten in de opkomst van het moderne leespubliek vooruitlopen op de nieuwsgierige, maar elk risico vermijdende internet-junkie. Uitgaande van recente onderzoeken naar het isolement dat veel internetgebruikers ervaren, toont Dreyfus (...) aan hoe het internet, door zijn nadruk op privé-ervaringen, gebruikers berooft van wezenlijke, belichaamde vermogens zoals vertrouwen, stemmingen en betrokkenheid bij met anderen gedeelde lokale aangelegenheden. _Internet_ is verplichte kost voor iedereen die on line is en is geïnteressseerd in onze plaats in de 'e-revolutie'.

In previous work I urged that the perceptual experience we rational animals enjoy is informed by capacities that belong to our rationality, and - in passing - that something similar holds for our intentional action. In his Presidential Address, Hubert Dreyfus argued that I thereby embraced a myth, "the Myth of the Mental". According to Dreyfus, I cannot accommodate the phenomenology of unreflective bodily coping, and its importance as a background for the conceptual capacities exercised in reflective intellectual activity. (...) My paper responds to this accusation. Dreyfus misreads my invocation of Aristotle, and is thereby led to suppose, wrongly, that I conceive rationality as detached, brought to bear on practical predicaments from a standpoint other than one of immersion in them. I urge that even unreflective bodily coping, on the part of rational animals, is informed by their rationality. Dreyfus mentions Heidegger’s distinction, which is picked up by Gadamer, between being oriented towards the world and merely inhabiting an environment. But he sets it aside, whereas it is crucial for the issue between us. Engaged bodily coping involves responsiveness to affordances, and responsiveness to affordances on the part of rational animals belongs to their relation to the world. I explain how the idea that conceptual capacities are actualized in our perceptual experience is connected with the thought that our perceptual experience opens us to the world. Finally, I suggest that the real myth in this area is the conception of rationality underlying Dreyfus’s resistance to my picture. (shrink)

I want to combine two hitherto largely independent research projects, scientific understanding and mechanistic explanations. Understanding is not only achieved by answering why-questions, that is, by providing scientific explanations, but also by answering what-questions, that is, by providing what I call scientific descriptions. Based on this distinction, I develop three forms of understanding: understanding-what, understanding-why, and understanding-how. I argue that understanding-how is a particularly deep form of understanding, because it is based on mechanistic explanations, which answer why something happens in (...) virtue of what it is made of. I apply the three forms of understanding to two case studies: first, to the historical development of thermodynamics and, second, to the differences between the Clausius and the Boltzmann entropy in explaining thermodynamic processes.

Dit boek is een hommage aan de filosoof Hubert Dethier (°21 juli 1933), die we zeker in de rij kunnen plaatsen van denkers als Jaap Kruithof, Hans Achterhuis en Etienne Vermeersch. Deze hommage is geen chronologische biografie. Het is daarentegen wel een verhaal waarin het leven van Hubert Dethier verweven wordt met de geschiedenis van zijn denken. Een denken dat zich situeert in de tweede helft van de vorige eeuw en het begin van de huidige eeuw en zich (...) moeiteloos projecteert naar de toekomst. Ontegensprekelijk een woelige en gewelddadige periode, maar ook een tijdgewricht van hoop en verwachting van het “nieuwe”.0. (shrink)

Because Bertrand Russell adopted much of the logical symbolism of Peano, because Russell always had a high regard for the great Italian mathematician, and because Russell held the logicist thesis so strongly, many English-speaking mathematicians have been led to classify Peano as a logicist, or at least as a forerunner of the logicist school. An attempt is made here to deny this by showing that Peano's primary interest was in axiomatics, that he never used the mathematical logic developed by him (...) for the reduction of mathematical concepts to logical concepts, and that, instead, he denied the validity of such a reduction.

Human intuition and perception are basic and essential phenomena of consciousness. As such, they will never be replicated by computers. This is the challenging notion of Hubert Dreyfus, Ph. D., archcritic of the artificial intelligence establishment. It's important to emphasize that he doesn't believe that AI is fundamentally impossible, only that the current research program is fatally flawed. Instead, he argues that to get a device (or devices) with human-like intelligence would require them to have a human-like being in (...) the world, which would require them to have bodies more or less like ours, and social acculturation (i.e. a society) more or less like ours. This helps to explain the practical problems in implementing artificial intelligence algorithms. (shrink)

My purpose here is to describe a type of argument characterized by the fact that one of its premises is a directive—i.e. what is expressed by a directive sentence: a general instruction how to proceed or act. This directive premise brings an ostensive mechanism for the inclusion of visual or multimodal elements in an argument. If an argument is an invitation to inference, by using such a directive utterance the addresser is inviting the addressee to make an inference from an (...) image, not from a proposition. Hence I will call them arguments from ostension or from deixis. (shrink)

Se ha señalado con frecuencia el escaso tratamiento de Heidegger acerca del amor. Se busca recuperar y articular algunas alusiones importantes. Cabe distinguir tres registros temáticos: como modo de “encontrarse”, como “actitud” con los otros y como rasgo del “ser mismo”. Se intenta no solo comprender el fenómeno amoroso en el pensamiento heideggeriano, sino mostrar la incidencia que habría tenido en la interpretación de otras cuestiones y, sobre todo, en el asunto central sobre el sen-tido del Ser.

Les Presses universitaires de France ont publié, en 1994, une Encyclopédie universelle de philosophie, dans laquelle Hubert Mono Ndjana est présenté comme un spécialiste de la pensée des hommes politiques. Il avait en effet traduit en français Obiang Nguema Mbasogo en 1980 (Un Pari pour la liberté), publié un ouvrage en 1985 sur le chef d'Etat de son pays (L'Idée sociale chez Paul Biya), et deux autres sur la pensée et le pays de Kim Il Sung (Révolution et création (...) et Regard sur la Corée), en 1987. Sa pensée s'est également et abondamment préoccupée de la question du politique et des préoccupations épistémologiques.

Religiose Vielfalt ist nicht erst eine Erscheinung der "westlichen Moderne". Vielmehr existierten schon in fruhen Zeiten und an verschiedenen Orten der Welt oft mehrere Religionen nebeneinander, sei es dass diese unterschiedlichen Ursprungs waren oder sich aufgrund divergierender Auffassungen der religiosen Akteure innerhalb einer gemeinsamen Tradition ausdifferenzierten. Nicht immer war und ist diese Koexistenz eine friedliche. Die Religion der anderen wird haufig als "deviant" wahrgenommen oder gar als "nonkonformistisch" stigmatisiert und sanktioniert, bis hin zur physischen Vernichtung der "Devianten". Im vorliegenden Band (...) gehen vierzehn ausgewiesene Wissenschaftler_innen aus den Fachgebieten Religionswissenschaft, Soziologie, Sinologie und Judaistik aus ihrer jeweiligen fachlichen Perspektive und anhand diverser Fallbeispiele aus Geschichte und Gegenwart der Frage nach, unter welchen Umstanden, aus welchen Grunden und mit welchen Folgen religiose Pluralitat als Problem wahrgenommen wird. Das Buch verbindet so systematische Fragestellungen mit empirischen Fallbeispielen und liefert damit eine ausgezeichnete Grundlage fur die Erforschung des gesellschaftlichen Umgangs mit religioser Pluralitat.

Philosophers now seem to agree that frequentism is an untenable strategy to explain the meaning of probabilities. Nevertheless, I want to revive frequentism, and I will do so by grounding probabilities on typicality in the same way as the thermodynamic arrow of time can be grounded on typicality within statistical mechanics. This account, which I will call typicality frequentism, will evade the major criticisms raised against previous forms of frequentism. In this theory, probabilities arise within a physical theory from statistical (...) behavior of almost all initial conditions. The main advantage of typicality frequentism is that it shows which kinds of probabilities (that also have empirical relevance) can be derived from physics. Although one cannot recover all probability talk in this account, this is rather a virtue than a vice, because it shows which types of probabilities can in fact arise from physics and which types need to be explained in different ways, thereby opening the path for a pluralistic account of probabilities.
