Loneliness in medicine is a serious problem not just for patients, for whom illness is intrinsically isolating, but also for physicians in the contemporary condition of medicine. We explore this problem by investigating the ideal physician-patient relationship, whose analogy with friendship has held enduring normative appeal. Drawing from Talbot Brewer and Nir Ben-Moshe, we argue that this appeal lies in a dynamic form of companionship incompatible with static models of friendship-like physician-patient relationships: a mutual refinement of embodied virtue that draws (...) both persons together. The ideal physician-patient relationship has a dialectical character that fosters each member's improvement of phenomenologically recognizing and embodying moral virtues. A key component of this dynamic is a commitment to the common goal of the patient's health, realized through joint interactivities and conversations over time. The physician's presence to the patient's suffering—understood best as an alienating phenomenological condition for the patient—orients and discloses possibilities for virtuous caregiving by structuring the meanings of the goals, conversations, and joint narrative constitutive of their relationship. Presence to suffering, paradoxically, is perhaps an important prerequisite for this dynamic partnership. These activities dialectically build an interpretive horizon of understanding through which moral goods and character refinement—in and for the other—may become revealed for both persons in their shared being-in-the-world. This analysis of suffering, mood, and revealing of (possible) moral goods has implications for addressing the modern problem of loneliness for patients and physicians, who are increasingly inhibited from building flourishing relationships with each other.

Our aim in this paper is to explicate some unexpected and striking similarities and equally important differences, which have not been discussed in the literature, between Wittgenstein's methodology and the approach of Chinese Chan or Japanese Zen Buddhism. We say ?unexpected? similarities because it is not a common practice, especially in the analytic tradition, to invest very much in comparative philosophy. The peculiarity of this study will be further accentuated in the view of those of the ?old school? who see (...) Wittgenstein as a logical positivist, and Zen as a religious excuse for militarism or sadomasochism. If the second claim were true, the following investigation would not only be futile but also impossible. That the first claim, concerning the ?old school? perspective on Wittgenstein, is incorrect, we will demonstrate in the ensuing discussion. By now more experts have come to accept this claim and we hope that our comparative perspective will add even more momentum. (shrink)

This paper is a philosophical discussion about the link between utopianism and responsibility. It argues that our time demands a strong practice of political responsibility in both organizations and society based on what has been called ‘real utopianism’. It takes as a starting point Hans Jonas’ critique of utopianism. Keeping in mind the horrors of the Second World War this Jewish thinker disconnected the principle of responsibility from the idea of utopianism, and connected it to a ‘heuristics of fear’ (...) – we should be careful with ‘wild’ new technologies, but also with new utopian perspectives. In a second step Jonas’ predecessors and utopian thinkers Martin Buber, Ernst Bloch and Ernest Callenbach are revisited. They show that a fully conceptualized idea of utopianism includes at least three dimensions of responsibility: subsistence, justice and spirituality. I then argue that if one digs deeper into the work of Jonas, it seems that the concept of responsibility in fact implies the courage to overcome a heuristics of fear. This paper therefore argues that there is no need to radically disjunct responsibility from utopianism and that the concept of responsibility actually opens a path to ‘real utopianism’. Such a concept of responsibility can best be supported by a confessionally neutral but nonetheless spiritual eco-humanist worldview that develops a new attitude towards nature, in which (eco)asceticism, morality and spirituality become intertwined.

In lieu of an abstract, here is a brief excerpt of the content:Spinoza and the Theory of Organism HANS JONAS I CARTESIANDUALISMlanded speculation on the nature of life in an impasse: intelligible as, on principles of mechanics, the correlation of structure and function became within the res extensa, that of structure-plus-function with feeling or experience (modes of the res cogitans) was lost in the bifurcation, and thereby the fact of life itself became unintelligible at the same time that the (...) explanation of its bodily performance seemed to be assured. The impasse became manifest in Occasionalism : its tour de force of an extraneous, divine "synchronization" of the outer and the inner world (the latter denied to animals) not only suffered from its extreme artificiality, the common failing of such ad hoc constructions, but even at so high a cost failed to accomplish its theoretical purpose by its own terms. For the animal machine, like any machine, raises beyond the question of the "how" that of the "what for" of its functioning---of the purpose for which it had thus been constructed by its maker.1 Its performance, however devoid of immanent teleology, must serve an end, and that end must be someone's end. This end may (directly) be itself, as indeed Descartes had implied when declaring self-preservation to be the effect of the functioning of the organic automaton. In that case the existence as such of the machine would be its end--either terminally, or in turn to benefit something else. In the former case, the machine would have to be more than a machine, for a mere machine cannot enioy its existence. But since, by the rigorous conception of the res extensa, it cannot be more than a machine, its function and/or existence must serve something other than itself. Automata in Descartes ' time were mainly for entertainment (rather than work). But the raison d'etre of the living kingdom could not well be seen in God's indulging his mechanical abilities or in the amusement of celestial spectators--especially since mere complexity of arrangement does not create new quality and thus add something to the unrelieved sameness of the simple substratum that might enrich the spectrum of being. For quality, beyond the primitive determinations of the extended per se, is the subjective creature of sensation, the confused representation of quantity in a mind; and thus organisms cannot harbor it because as mere machines they lack mentality, and pure spirits cannot because they lack sensuality, or the privilege of confusion and thereby of illusion with its possible enjoyment. And as to their intellectual enjoyment, even that, deprived of the thrill of discovery by the same token, would pale in the contemplation of what to sufficiently large The concept of "machine," adopted for its strict confinementto efficientcause, is still a finalisticconcept,even thoughthe final cause is no longer internal to the entity, as a mode of its own operation,but external to it as antecedent design. [43] 44 HISTORY OF PHILOSOPHY intellects is nothing but the ever-repeated exemplification of the same few, elementary (and ultimately trivial) truths. There remained, then, the time-honored--Stoic as well as Christian--idea that plants and animals are for the benefit of Man. Indeed, since the existence of a living world is the necessary condition for the existence of any of its members, the self-justifying nature of at least one such member (= species) would justify the existence of the whole. In Stoicism, Man provided this end by his possession of reason, which makes him the culmination of a terrestrial scale of being that is also self-justifying throughout all its grades (the end as the best of many that are good in degrees) ; in Christianity, by his possession of an immortal soul, which makes him the sole imago Dei in creation (the end as the sole issue at stake) ; and Cartesian dualism radicalized this latter position by making man even the sole possessor of inwardness or "soul" of any kind, thus the only one of whom "end" can meaningfully be predicated as he alone can entertain ends. All other life then, the product of physical necessity, can be considered his means. However, this traditional idea, in its anthropocentric vanity never a... (shrink)

Benjamin Libet's celebrated experiments concerning freedom elicited numerous attempts of _philosophical_ repudiation. Ten years ago, however, Judy Trevena and Jeff Miller published a _technical_ objection; they claim to have detected a,,smearing artifact" in Libet's calculations. This rests on a misunderstanding of Libet's methodology. In my reconstruction of Libet's argument, he draws an abductive inference to the best explanation. Now, Trevena's and Miller's objection does indeed lead to alternative explanations of Libet's measurements. These alternatives are _ad hoc_ and extremely improbable. They (...) constitute worse explanations than the explanation offered by Libet. _German_ Benjamin Libets bahnbrechende Experimente zur Willensfreiheit aus den Achtziger Jahren des vorigen Jahrhunderts gehören längst zu den Klassikern der Experimentalkunst. Aus _philosophischer_ Perspektive sind sie oft kritisiert worden; unabhängig davon ist zu Beginn des neuen Jahrtausends ein _technischer_ Einwand gegen Libet prominent geworden, der von Freiheitsfreunden gerne zitiert wird. Er geht auf Judy Trevena und Jeff Miller zurück und besteht in dem Vorwurf, dass Libet mit seiner Berechnung der _gemittelten_ Bereitschaftspotential-Kurven die wahren Verhältnisse verschmiere und dabei aus mathematischen Gründen den Anstiegs-Zeitpunkt des Bereitschaftspotentials künstlich nach vorne verschiebe – das ist der Vorwurf des sog. Verschmierungsartefakts. Ich zeige, dass der Vorwurf nicht sticht. Er beruht auf einem Missverständnis der Schlussmethode Libets. Laut meiner wissenschaftstheoretischen Rekonstruktion zieht Libet weder deduktive noch induktive Schlüsse aus seinen Einzelbeobachtungen; er schließt abduktiv, d.h. er schließt auf die beste Erklärung seiner Einzelbeobachtungen. Wie eine genaue arithmetische Analyse zeigt, bieten die Alternativ-Erklärungen, unter denen sich das Verschmierungsartefakt bewahrheiten würde, schlechtere Erklärungen als Libets Erklärung – sie sind an den Haaren herbeigezogen und extrem unwahrscheinlich.

Sprachliche Ausdrücke, mit deren Hilfe wir Spiele beschreiben und vorantreiben, sind in ihrer Verwendungsweise so vielfältig wie kaum irgendwelche anderen Ausdrücke. Und sie haben eine Eigenschaft, die man mit dem Thema Spiel eher nicht in Verbindung bringen würde: Sie eignen sich dazu, auf substantive Weise Metaphysik zu treiben oder wieder ingangzubringen. Diese Art der Starthilfe hat die jahrtausendealte Metaphysik (metaphysica specialis) neuerdings nötig. Seit knapp hundert Jahren steht sie im Verdacht, auf nichts besseres hinauszulaufen als leeres, unverständliches Wortgeklingel. Wer diesen (...) sprachphilosophischen Verdacht auszuräumen wünscht, tut gut daran, unverdächtige Redebereiche zu bemühen. In der Tat, mithilfe unserer höchst robusten, völlig alltäglichen Rede vom Spielen und beim Spielen können wir tiefe metaphysische Möglichkeiten verständlich machen, etwa die Möglichkeit einer Wirklichkeit jenseits oder oberhalb des Bereichs derjenigen Wirklichkeit, die wir Natur oder physisches Universum nennen. Dazu betrachte ich ein philosophisches Gedankenspiel (das den Matrix-Filmen zugrundeliegt und all unsere Wissensansprüche zu unterminieren scheint): Wir sind Gehirne im Tank, d.h. wir haben keinen vollständigen menschlichen Körper, sondern nur ein Gehirn, das in einem Tank mit Nährflüssigkeit schwebt; die Nerven-Enden dieser Gehirne sind mit einem Supercomputer verbunden, der uns die Illusion verschafft, dass alles in Ordnung sei. Hiergegen hat Hilary Putnam folgende sprachphilosophische Schwierigkeit aufgeworfen: Wie soll ein Gehirn im Tank seine eigene Situation treffend auf den Punkt bringen, wenn doch seine Ausdrücke "Tiger", "Gehirn", "Tank" usw. allesamt nicht mit echten Tigern, Gehirnen usw. verknüpft sind, sondern mit Nullen und Einsen im Computer? Putnam trieb diese Schwierigkeit bis an den Punkt, an dem sich zweifelsfrei beweisen lässt, dass wir keine Gehirne im Tank sein können. Und da hatte er meiner Ansicht nach recht. Wie ich meine, sollten wir uns nicht darüber den Kopf zerbrechen, ob wir ein Gehirn im Tank sind, sondern darüber, ob wir in einer analogen Situation stecken, um eine Ebene nach oben verschoben. Um die Metaphern dieser Formulierung des Problems auszupacken, setze ich Spielvokabeln ein. Wegen ihrer atemberaubenden Flexibilität brauchen sie (im Unterschied zur naturwissenschaftlichen Sprache) bei Übersetzung aus der Tanksprache in unsere Sprache nicht verändert zu werden; solche Ausdrücke heißen semantisch stabil. Mit ihrer Hilfe können wir gravierende metaphysische Möglichkeiten aufwerfen, z.B.: "Jemand, der nicht aus Materie besteht und nicht in meinem physischen Universum vorkommt, treibt mit mir von außerhalb seine Machtspielchen". Damit beziehen wir uns vielleicht auf die außerirdische Programmiererin der Simulation, in der wir möglicherweise doch stecken. Weniger respektlos formuliert, wäre das die Frage eines allmächtigen Schöpfergottes außerhalb unserer physikalischen Raumzeit: Metaphysik pur. (shrink)

Quine behauptet, dass uns der Holismus (d.h. die Quine/Duhem-These) daran hindert, Synonymie zu definieren. In "Word and Object" weist er einen Synonymiebegriff zurück, der selbst dann gut funktioniert, wenn der Holismus zutrifft. Dieser Begriff lässt sich so definieren: R und S sind synonym, wenn für alle Sätze T die logische Konjunktion aus R und T reizsynonym zur Konjunktion aus S und T ist. Dieser Begriff entgeht Quines bedeutungsskeptischen, holistischen Einwänden. Anders als Quine gemeint hat, ist der Begriff enger als sein (...) Begriff der Reizsynonymie – insbesondere bei Anwendung auf Sätze mit weniger als kritischer semantischer Masse. Fazit: Wir können Synonymie selbst dann sauber definieren, wenn wir Quines Holismus, Naturalismus, Behaviorismus und radikale Übersetzung mitmachen. Quines Bedeutungsskepsis sollte sogar auf Quines eigenem Territorium zurückgewiesen werden. (shrink)

Epistemic theories of truth, such as those presumed to be typical for anti-realism, can be characterised as saying that what is true can be known in principle: p → ◊Kp. However, with statements of the form “p & ¬Kp”, a contradiction arises if they are both true and known. Analysis of the nature of the paradox shows that such statements refute epistemic theories of truth only if the the anti-realist motivation for epistemic theories of truth is not taken into account. (...) The motivation in a link of understandability ans meaningful- ness suggests to change the above principle and to restrict the theory to logically simple sentences, in which case the paradox does not arise. This suggestion also allows to see the deep philosophical problems for anti-realism those counterexamples are pointing at. (shrink)

In May 2017, my book ‘Conversations on Art and Aesthetics’ appeared. It contains conversations with, and photographic portraits of, ten prominent philosophers of art. They are Noël Carroll, Gregory Currie, Arthur Danto, Cynthia Freeland, Paul Guyer, Carolyn Korsmeyer, Jerrold Levinson, Jenefer Robinson, Roger Scruton, and Kendall Walton. The book has two main aims. One is to provide a broad and accessible overview of what aesthetics as a subfield of philosophy has to offer. The other is to stimulate new work in (...) this area of research. In this brief paper I’d like to say a bit more about this second objective. Current research is rarely conducted or communicated in the form of conversations, so the question arises: how can a book like mine fit with and feed into a research culture which is very much dominated by the format of the journal article?

Newtons experimentum crucis hat ein komplementares Gegenstück, d.h. ein Experiment, in dem die Rollen von Licht und Schatten genau ausgetauscht sind. Statt wie Newton in der Dunkelkammer zu experimentieren, müssen wir das Komplement des experimentum crucis in einer Streulichtkammer aufbauen (deren Wände sog. Lambertstrahler sind). Wenn es dieses umgestülpte Experiment wirklich gibt, dann liefert es für jeden newtonischen Beweis einen umgestülpten Gegenbeweis, dessen Konklusion die Heterogenitat der Schatten wäre (also die Behauptung, dass nicht weißes Licht, sondern schwarze Schatten eine heterogene (...) Mischung verschiedenfarbiger Strahlen mit unterschiedlichen Brechungseigenschaften seien). Dass Newtons experimentum crucis in diesem Sinne umgestülpt werden kann, wird von Newtons eigener Theorie impliziert. Mehr noch, inzwischen ist der empirische Nachweis der Umstülpung gelungen.

Context: The majority of contemporary enactivist work is influenced by the philosophical biology of Hans Jonas. Jonas credits all living organisms with experience that involves particular “existential” structures: nascent forms of concern for self-preservation and desire for objects and outcomes that promote well-being. We argue that Jonas’s attitude towards living systems involves a problematic anthropomorphism that threatens to place enactivism at odds with cognitive science, and undermine its legitimate aims to become a new paradigm for scientific investigation and understanding (...) of the mind. Problem: Enactivism needs to address the tension between its Jonasian influences and its aspirations to become a new paradigm for cognitive science. By relying on Jonasian phenomenology, contemporary enactivism obscures alternative ways in which phenomenology can be more smoothly integrated with cognitive science. Method: We outline the historical relationship between enactivism and phenomenology, and explain why anthropomorphism is problematic for a research program that aspires to become a new paradigm for cognitive science. We examine the roots of Jonas’s existential interpretation of biological facts, and describe how and why Jonas himself understood his project as founded on an anthropomorphic assumption that is incompatible with a crucial methodological assumption of scientific enquiry: the prohibition of unexplained natural purposes. We describe the way in which phenomenology can be integrated into Maturana’s autopoietic theory, and use this as an example of how an alternative, non-anthropomorphic science of the biological roots of cognition might proceed. Results: Our analysis reveals a crucial tension between Jonas’s influence on enactivism and enactivism’s paradigmatic aspirations. This suggests the possibility of, and need to investigate, other ways of integrating phenomenology with cognitive science that do not succumb to this tension. Implications: In light of this, enactivists should either eliminate the Jonasian inference from properties of our human experience to properties of the experience of all living organisms, or articulate an alternative conception of scientific enquiry that can tolerate the anthropomorphism this inference entails. The Maturanian view we present in the article’s final section constitutes a possible framework within which enactivist tools and concepts can be used to understand cognition and phenomenology, and that does not involve a problematic anthropomorphism. Constructivist content: Any constructivist approach that aims for integration with current scientific practice must either avoid the type of anthropomorphic inference on which Jonas bases his work, or specify a new conception of scientific enquiry that renders anthropomorphism unproblematic.

In recent years, philosophers have used expressions of Wittgenstein’s (e.g. “language-games,” “form of life,” and “family resemblance”) in attempts to conceive of the discipline of philosophy in a broad, open, and perhaps global way. These Wittgenstein-inspired approaches indicate an awareness of the importance of cultural and historical diversity for approaching philosophical questions. While some philosophers have taken inspiration from Wittgenstein in embracing contextualism in philosophical hermeneutics, Wittgenstein himself was more instrumental than contextual in his treatment of other philosophers; his focus (...) in his writings was on his own philosophical problems. Does this mean that Wittgensteinian philosophy is a poor resource after all for comparative, cross-cultural, or globally-engaged philosophy (i.e. if it is properly Wittgensteinian)? In this article, I examine the relevance of Wittgenstein to contextually-sensitive philosophy through studies of his conceptions of history and culture, his interest in Spengler’s philosophy of history, and recent scholarship by Hans-Johann Glock and Hans Sluga on the place of contextualism in Wittgenstein’s analysis of philosophical problems. Ultimately, this article advances the view that there are strong resources in Wittgenstein’s philosophy for those seeking a more globally-engaged approach to the field. (shrink)

Abstract in English, German, French and Croatian -/- In the paper “The ‘Bubbling Up’ of Subterranean Politics in Europe”, which was published in 2013 in the Journal of Civil Society, Mary Kaldor and Sabine Selchow attempted to reveal the specific qualities of the uprisings which emerged after the year 2010 in some European countries, such as Germany, Spain, Italy, England etc. According to the authors, the mode of organization which forms the main body of these emancipatory movements obtains its basic (...) logic from the world of the Internet. The use of the Internet requires a re-evaluation of negative philosophical commentary regarding technology. In the context of twentieth-century philosophy, Martin Heidegger and Herbert Marcuse are the most influential philosophers who studied the negative aspects of technology. Heidegger portrayed the destructive effects of scientific reasoning and technology on the Western culture through the criticism of the traditional Western metaphysics on a phenomenological-ontological level. Marcuse, belonging to the tradition of Western Marxism, formed his critique of technology in the context of the concept of instrumental rationality and the critique of advanced industrial society and capitalism. Although the starting points of their perspectives on technology and the underlying purposes of their critiques of technology were different, it may be asserted that both have a rather negative and almost entirely pessimistic disposition towards technology. Heidegger’s and Marcuse’s criticisms of technology will be discussed in this context and the differences and similarities between these criticisms will be shown. Finally, the paper will emphasise the question of the possibility of a positive role of technology. Technology can serve as an alternative to negative uses by shedding light on the relation between the current uprisings and the Internet.

Zusammenfassung In dem Artikel „The ‘Bubbling Up’ of Subterranean Politics in Europe”, veröffentlicht im Jahre 2013 im Journal of Civil Society, versuchten Mary Kaldor und Sabine Selchow die spezifischen Qualitäten der Aufstände zum Ausdruck zu bringen, die nach 2010 in den europäischen Ländern ausbrachen – Deutschland, Spanien, Italien, England usw. Nach Ansicht der Autoren erhält der Modus der Organisation, der den Hauptkörper dieser emanzipatorischen Bewegungen bildet, seine grundlegende Logik aus der Welt des Internets. Die Analogie mit dem Internet erfor- dert eine Neubewertung der negativen Kommentare über die Technologie aus philosophischer Perspektive. Martin Heidegger und Herbert Marcuse sind die einflussreichsten Philosophen, die sich mit den negativen Aspekten der Technologie in der Philosophie des 20. Jahrhunderts befasst haben. Heidegger schilderte die zerstörerischen Auswirkungen der wissenschaftlichen Vernunft und Technologie auf die westliche Kultur durch die Kritik an der traditionellen abend- ländischen Metaphysik auf der phänomenologisch-ontologischen Ebene, während Marcuse, ein Mitglied des westlichen Marxismus, seine Kritik an der Technologie im Rahmen des Konzepts der instrumentellen Rationalität und der Kritik der fortgeschrittenen Industriegesellschaft und Kapitalismus geformt hat. Obgleich die Ansatzpunkte ihrer Perspektiven über die Technologie und die zugrunde liegenden Zwecke ihrer Kritik an der Technologie unterschiedlich waren, kann behauptet werden, dass beide eine eher negative und fast völlig pessimistische Einstellung zur Technologie hatten. In diesem Zusammenhang werden Heideggers und Marcuses Kritiken an der Technologie diskutiert sowie Unterschiede und Ähnlichkeiten zwischen den beiden Kri- tiken aufgezeigt. Abschließend unterstreicht das Paper die Frage nach der Möglichkeit einer positiven Rolle für die Technologie, die als Alternative zur negativen Perspektive dienen kann, indem sie Licht in das Verhältnis zwischen aktuellen Aufständen und Internet bringt.

Résumé Dans l’article « The “Bubbling Up” of Suberranean Politics in Europe » publié en 2013 dans Journal of Civil Society, Mary Kaldor et Sabine Selchow tentent de mettre en lumière les caractéristiques spécifiques des révoltes qui ont fait jour après 2010 dans certains pays européens – Allemagne, Espagne, Italie, Angleterre, etc. Selon nos auteures, le mode d’organisation qui a formé le corps essentiel de ces mouvements émancipatoires tire sa logique de base du monde de l’internet. Cette analogie avec l’internet requiert une réévaluation, à partir d’un point de vue philosophique, des commentaires négatifs sur la technologie. Martin Heidegger et Herbert Marcuse sont les philosophes les plus influents ayant travaillé sur les aspects négatifs de la technologie au sein de la philosophie du XXe siècle. Heidegger a dépeint les effets destructeurs de la raison scientifique et de la technologie de notre culture occidentale à travers son criticisme de la métaphysique traditionnelle occidentale à un niveau phénoménologico-ontologique, tandis que Marcuse, membre du « communisme occidentale », a formé une critique de la technologie au sein du concept de rationalité instrumentale et une critique de la société industrielle avancée et du capitalisme. Bien que le point de départ de leur perspective sur la technologie et que le but sous-jacent de leur critique diffèrent, il est possible d’affirmer que leur point commun est d’avoir posé un regard négatif et presque entièrement pessimiste sur la technologie. À cet égard, le criticisme d’Heidegger et de Marcuse vont être abordés afin d’en soulever les différences et les similarités. Enfin, cet article mettra l’accent sur la possibilité d’un rôle positif de la technologie qui pourrait servir d’alternative aux perspectives négatives en faisant la lumière sur le lien entre les révoltes actuelles et l’internet.

Sažetak U članku »The ‘Bubbling Up’ of Subterranean Politics in Europe«, objavljenom 2013. u časopisu Journal of Civil Society, Mary Kaldor i Sabine Selchow pokušale su otkriti specifične značajke pobuna koje su se javila nakon 2010. godine u europskim zemljama poput Njemačke, Španjolske, Italije, Engleske itd. Prema autoricama, način organiziranja koji čini glavno tijelo ovih emancipatornih pokreta preuzima svoju osnovnu logiku iz svijeta Interneta. Analogija s Internetom zahtijeva ponovnu evaluaciju negativnih komentara o tehnici iz filozofske perspektive. Martin Heidegger i Herbert Marcuse najutjecajniji su filozofi 20. stoljeća koji su se bavili negativnim aspektima tehnike. Heidegger je prikazao destruktivne učinke znanstvene racionalnosti i tehnike na zapadnu kulturu kroz kritiku tradicionalne zapadne metafizike na fenomenološko-ontološkoj razini, dok je Marcuse, kao predstavnik zapadnoga marksizma, oblikovao svoju kritiku tehnike u kontekstu pojma instrumentalne racionalnosti te kritike razvijenog industrijskog društva i kapitalizma. Iako su polazišne točke njihovih pogleda na tehniku, kao i osnovne svrhe kritike tehnike, različite, može se reći da obojica imaju poprilično negativno i gotovo u potpunosti pesimističko shvaćanje tehnologije. U tom će se kontekstu razmotriti Heideggerova i Marcuseova kritika tehnike kao i razlike i sličnosti između tih dvaju pristupa. Zaključno će rad naglasiti mogućnost pozitivne uloge tehnike, koja može služiti kao alternativa negativnoj perspektivi osvjetljavajući odnos između nedavnih pobuna i interneta.

Not only did Paracelsus (1493-1541) censure the logic of the Aristotelians, but also their "Godless" approach to questioning nature. He declared that Aristotle was “a heathen whose work had rightly been condemned repeatedly in church councils." In this essay I elucidate some of the more salient features of Paracelsus’s "epistemology," and draw parallels between his notion of experientia (Erfahrung) and that of Hans-Georg Gadamer. I also discuss Paracelsus’s educational metaphor, his creation myth, and the mysterious doctrine of signatures en (...) route to uncovering his peculiar understanding of the relationship between theory, practice, and experience.

En el presente trabajo, (i) caracterizamos algunos de estos desacuerdos como desacuerdos profundos. Además, (ii) mostramos que los desacuerdos profundos sobre ontología científica pueden surgir no solo de la adopción de diferentes stances epistémicas, sino entre posiciones que se encuadran dentro de una misma stance. El desarrollo de ese punto nos permite, a su vez, establecer una distinción entre tipos (...) de desacuerdos profundos y explorar la posibilidad de que existan diferencias de grado entre ellos.

The Early Han enjoyed some prosperity while it struggled with centralization and political control of the kingdom.

The aim of the paper is to briefly present the philosophy of Hans Wagner (1917-2000) as belonging to the last phase of the development of the German transcendental philosophy. Hans Wagner’s philosophy is presented as an attempt to synthesize earlier positions developed on the basis of this tradition, namely the synthesis of (a) neo-Kantianism with post-neo-Kantianism, (b) Kant's philosophy with Hegel's philosophy, (c) neo-Kantian transcendentalism with Husserl's transcendentalism, (d) the philosophy of transcendental subject (Kant, neo-Kantianism, phenomenology) with the (...) philosophy of empirical subject (Hönigswald, Heidegger, Sartre). The main theoretical figure of Hans Wagner’s philosophy is the problem of two aspects of human thinking: its absoluteness and finiteness. According to Wagner development of the philosophical reflection, which we can observe on the example of the evolution of - originating from Kant - transcendental philosophy, leads to an explanation of the possibility to reconcile these two aspects of human thinking, and thus to answer the very question: how is it possible that our thinking can be both absolute and finished, and what are the consequences of this fact for the status of all cultural products of human thinking, such as science, morality or law.

«Hva er det vi egentlig mener når vi sier, mennesket er dødelig?» spør Woody Allen i boken The Insanity Defence. Han legger til: «Det er åpenbart ikke et kompliment.»1 Jeg tror Woody tar feil her. Vår dødelighet er et kompliment – eller i det minste av det gode – siden livet uten døden ville være katastrofalt. Udødelige liv fører til dyp kjedsomhet, eksistensiell angst og en radikal form for verdinihilistisk tilværelse. Grunnen er at udødeligheten gjør at vi en gang i (...) fremtiden må konfronteres med de radikalt livsfiendtlige stadiene av universets historie. Jeg argumenterer for at dette er en skjebne langt verre enn døden. Konklusjonen blir derfor, med et nikk til Voltaire, at om døden ikke hadde eksistert, hadde vi vært nødt til å finne den opp. (shrink)

RÉSUMÉ: Cet article propose une analyse détaillée des considérations de Hans-Georg Gadamer sur l’herméneutique théologique proprement dite. Pensée dans et pour la foi chrétienne, la conception de l’herméneutique théologique qu’il met en avant se veut essentiellement une herméneutique du texte biblique. Les réflexions de Gadamer sur ce thème nous conduisent cependant tout droit dans sa théorie de la littérature. La question directrice devient celle de la nature du texte religieux (entendons : du texte biblique, reçu en son unité canonique) (...) en tant que texte éminent, dont la structure singulière est mise en relief au moyen d’une éclairante comparaison avec les textes poétique, philosophie et juridique. L’Écriture, en tant qu’elle répond à la structure textuelle de la promesse, exige du lecteur une forme particulière d’appropriation qui trouve sa réalisation exemplaire dans la prédication. Toutefois, contre une lecture (Ommen, Eberhard, etc.) qui insiste sur la discontinuité de l’herméneutique théologique de Gadamer avec sa propre oeuvre philosophique, je soutiens la thèse de leur foncière cohérence. ABSTRACT: This paper offers a detailed analysis of Hans-Georg Gadamer’s considerations on theological hermeneutics proper. Thought within and for the Christian faith, the conception of theological hermeneutics he puts forward is mainly understood as a hermeneutics of the biblical text. However, Gadamer’s reflections on this theme bring us straight to his theory of literature. The guiding question becomes that about the nature of the religious text (meaning : the biblical text, received in its canonical unity) as eminent text, which peculiar structure is thrown into relief through an enlightening comparison with the poetical, the philosophical and the legal text. The Scripture, in that it has the textual structure of a promise, requires from the reader a particular form of appropriation, which finds its exemplary fulfillment in preaching. Against a reading that emphasizes discontinuity between Gadamer’s theological hermeneutics and his own philosophical work (Ommen, Eberhard, etc.) I defend the thesis of their fundamental coherence.

Dans cet article, nous examinerons le thème de la découverte en science. Nous soutiendrons qu’il est possible de définir une stratégie rationnelle soutenant la découverte au moyen du principe de l’abduction. Afin de démontrer cette thèse, il s’agira d’abord de diagnostiquer le problème de la complexité et de l’irrationalité de la découverte scientifique et de considérer la position néo-positiviste endossée par Karl Popper et Hans Reichenbach, selon laquelle la découverte ne peut faire l’objet d’une étude proprement logique ou épistémologique. (...) Par la suite, l’analyse se concentrera sur la position de Norwood R. Hanson qui, répondant et contredisant celle de Popper et de Reichenbach, affirme qu’il existe une « logique de la découverte », fondée sur le principe de l’abduction. Après avoir déployé l’argument de Hanson et explicité sa conception du principe de l’abduction, nous montrerons, en nous appuyant sur la vision d’Atocha Aliseda, comment l’abduction est liée à la découverte en science. Finalement, nous examinerons la notion d’inférence à la meilleure explication et le concept « d’hypothèse explicative » de Peter Lipton, ce qui permettra d’expliquer dans quelle mesure cette variante de l’abduction nous permet de comprendre les éléments et conditions qui favorisent la génération de découvertes en science.

Este trabajo se inserta en un proyecto mayor consistente en la evaluación moral de las políticas de seguridad a la luz del ideal político republicano de libertad como no dominación. Los razonamientos en torno al poder punitivo desde la Ilustración hasta nuestros días han tomado mayoritariamente como punto de partida la concepción de libertad hobbesiana. Según esta concepción un individuo es libre sí y sólo sí no padece interferencias provocadas por otros individuos. La interferencia es entendida aquí como una intervención (...) más o menos intencional. El Estado aparece como una institución que causa la libertad y, en particular, el derecho penal es una interferencia tan mala en sí misma como la coerción procedente de otras direcciones, pero justificada en la medida que disminuye el nivel general de coerción.• Si el nivel de interferencia producido por el derecho es menor que el nivel de interferencia privada que el aparato estatal evita que se produzca, entonces los individuos son más libres. La concepción hobbesiana de libertad se presenta así, utilizando la distinción introducida por Isaiah Berlin3 como un tipo de libertad negativa. A diferencia de la concepción clásica de libertad, presente por ejemplo en Aristóteles, no requiere de la existencia de autodominio o control -ya sea personal o político- por parte del individuo.

The Modern concept of truth, which subjects truth to certainty, broke the harmonious relation between reality and truth, that prevailed in Ancient and Medieval Philosophy. Hans-Georg Gadamer thinks that the main task of contemporary Philosophy is to recover the original harmony of being and knowledge. To shed light on the nature of this problem, we expound the metaphysical-theological foundation of truth, which is at the roots of Aristotelian and Thomistic Philosophies. Specifically, we analyze here the relation between being, truth (...) and logos in the Aristotelian treatise Perì Hermeneías, and in its Thomistic commentary. (shrink)

Premier ouvrage de l’histoire de la philosophie à être totalement consacré au concept d’entéléchie, il ne s’agira pas de proposer un essai historique allant de la mise en place de cette notion chez Aristote jusqu’à la conception biologique développée par Hans Driesch. Inscrit dans un projet plus global de compréhension du temps aristotélicien, c’est à une véritable refondation métaphysique du concept que ce travail nous convie. Si Kant, à l’ultime fin de sa première critique, avait admis qu’il n’existait que (...) deux voies possibles de fondation de l’a priori - la voie historique (platonicienne) empruntée par Hegel et la voie physiologique (aristotélicienne) qui sera la nôtre - la première partie de ce second volume prendra pour acquis qu’il n’existe pas de théorie qui puisse unifier ces deux pôles du savoir. Cela impliquera une scission entre deux mouvements irrationnels que sont le mouvement entéléchique aristotélicien et le mouvement dialectique platonicien. A partir du corps a priori du surhomme, le premier mouvement sera à la racine de la théorie de la connaissance (De la science) alors que le second sera au fondement de la théorie des valeurs (De l’Idéologie). En circonscrivant le mouvement dialectique dorien autour du noûs perse (iranien), ce travail offrira une première définition totalement négative du mouvement entéléchique appuyé, lui, sur le noûs ionien (« phénicien ») dont la seconde partie sera l’objet. De l’analyse de la substance première en passant par l’étude phénoménologique des schèmes de la camusité et du membre moteur, cette étude reviendra sur l’élasticité du tendon afin d’approcher non-phénoménalement le concept lui-même et tenter ainsi une première symphyse avec les rythmes circadiens de la biologie contemporaine.

DESENVOLVIMENTO EMBRIONÁRIO E DIFERENCIAÇÃO SEXUAL -/- E. I. C. da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim Departamento de Zootecnia – UFRPE sede -/- 1.1 INTRODUÇÃO O sexo foi definido como a soma das diferenças morfológicas, fisiológicas e psicológicas que distinguem o macho da fêmea permitindo a reprodução sexual e assegurando a continuidade das espécies. Os processos de diferenciação sexual são realizados durante o desenvolvimento embrionário, onde ocorre a proliferação, diferenciação e maturação das células germinativas e primordiais, precursoras (...) de ovócitos e espermatozoides em fêmeas e machos, respectivamente. Assim, os embriões machos e fêmeas iniciam o seu desenvolvimento de forma semelhante, de modo que em ambos os sexos se estabelecem em estruturas idênticas a partir das quais se formarão os órgãos reprodutores correspondentes a cada sexo. O conhecimento da origem e do desenvolvimento do aparelho genital é indispensável para entender sua função e as alterações que produzem infertilidade ou esterilidade. 1.2 DETERMINAÇÃO DO SEXO CROMOSSÔMICO Nos mamíferos, o sexo cromossômico é determinado no momento da fertilização, quando um óvulo, que contém um cromossomo X, é fecundado por um espermatozoide portador de um cromossomo X ou um cromossomo Y. No primeiro caso, o complemento cromossômico seria XX, o que originaria uma fêmea (sexo homogamético), e no segundo daria como resultado um macho com a fórmula cromossômica XY (sexo heterogâmico). 1.3 A GÔNADA INDIFERENCIADA A primeira manifestação das gônadas se aprecia no embrião em forma de um par de eminências longitudinais chamadas cristas ou dobras gonodais, situadas em ambos os lados da linha média entre os mesonefros (rins em desenvolvimento) e do mesentério dorsal. Nos embriões dos mamíferos, as células germinativas primordiais (CGP) manifestam-se em estágios precoces do desenvolvimento, podendo ser detectadas pela primeira vez na metade da gastrulação. As CGP são células grandes, de citoplasma claro e núcleo grande e redondo, localizadas na parede do saco vitelino, perto do alantoide. Essas células possuem grande capacidade de proliferação e vão migrar desde o endoderma do intestino e o epitélio do saco vitelino, através do mesentério, até as cristas gonodais. Isso ocorre por volta do 26° dia da gestação no bovino. Sua migração realiza-se graças aos movimentos de translocação passiva e deslocamento ameboide ativo. Desconhece-se o mecanismo pelo qual estas células são dirigidas para as cristas gonodais, porém foram estudadas algumas moléculas que se expressam durante sua migração e que poderiam desempenhar um papel importante na diferenciação deste tipo celular. A fosfatase alcalina é uma enzima que tem sido usada como marcador de CGP para determinar a sua origem e migração. Num estudo recente, foi inserido um marcador fluorescente que se exprime unicamente nas células germinativas primordiais de embriões transgênicos, e utilizando este marcador e a fosfatase alcalina determinou-se a origem e o padrão de migração destas células. O primeiro sinal de diferenciação das células germinativas primordiais é a expressão de fosfatase alcalina, e esta apareceu pela primeira vez na parte mais posterior da linha primitiva. No sétimo dia de desenvolvimento no embrião do camundongo, o endoderma visceral (AF+) é substituído pelo endoderma definitivo (AF-) originado na parte anterior da linha primitiva. O fator de transcrição Oct-4 é expresso nas CGP de ambos os sexos, pelo que acredita-se estar envolvido na mantença a totipotêncialidade das células. O receptor tirosina quinase, cujo ligante é o fator de Steel, é outra das moléculas que expressam as CGP. Tem sido demonstrado que este receptor possui um papel muito importante na sobrevivência deste tipo celular. Existem outros fatores que promovem a sobrevivência e/ou proliferação de CGP in vitro. Em experiências realizadas com o fator de transformação beta I (TGFβ-I), observou-se que este tem um efeito negativo sobre a proliferação das CGP. Outra atividade que tem sido postulada a este fator é o de um agente quimioatraente que possivelmente possa direcionar a migração destas células para a gônada. a) Um formado pelas células germinativas primordiais (precursoras dos gametas masculinos ou femininos), rodeadas de células somáticas das quais posteriormente se derivarão as células de Sertoli no macho e as células da granulosa na fêmea. b) O tecido que formará o estroma da gônada: tecido conjuntivo, vasos sanguíneos e as células intersticiais com atividade esteroidogênica (células de Leydig no testículo e a teca interna do ovário). As células somáticas do primórdio gonodal originam-se do mesoderma. Inicialmente são de três tipos: mesenquimáticas, mesoteliais e endoteliais. As células mesenquimáticas e mesoteliais iniciam grande atividade proliferativa ao chegar as CGP. Observa-se então uma condensação de células de origem mesotelial e mesenquimatoso que forma um agregado compacto denominado "blastema gonodal". A partir deste primórdio embrionário, diferenciam-se dois tecidos gonodais: os cordões sexuais e o estroma. Os cordões sexuais são arranjos epiteliais que se encontram delimitados por uma folha basal, e dentro deles encontramos as CGP. Por sua vez, no estroma encontram-se células do tipo mesenquimático e vasos sanguíneos. Neste momento, as gônadas são indiferenciadas e bipotencialmente sexuais, sendo impossível diferenciar, morfologicamente, uma gônada masculina de uma feminina, mas no caso dos machos genéticos já existe uma diferenciação da gônada a nível molecular. Nesta fase já se encontram presentes as estruturas das quais se desenvolvem os dutos mesonéfricos ou de Wolff precursores do aparelho genital masculino e os dutos paramesonéfricos ou de Müller que darão origem ao aparelho reprodutor feminino. Há uma série de fatores envolvidos no desenvolvimento precoce da gônada, entre os quais o fator esteroidogênico I (SFI: Steroidogenic fator l), que é um membro da subfamília de receptores nucleares, receptores órfãos. Este fator de transcrição tem um local de ligação ao DNA composto por dois dedos-de-Zinc. O SFI foi identificado como um ativador de genes envolvidos na biossíntese de esteroides em diferentes células. O SFI está presente durante o desenvolvimento embrionário em regiões associadas com funções endócrinas como gônadas, adrenais, pituitárias e hipotálamos. Os animais homozigotos para o gene SFI defeituoso, necessitam de gônadas e adrenais e têm a função gonadotrófica alterada. Os ratos sem SFI carecem de gonadotrofos e têm um desenvolvimento anormal do núcleo ventro-medial do hipotálamo; em particular as gônadas deixam de se desenvolver entre os dias 11 a 15 e degeneram-se por apoptose. No entanto, a crista genital forma-se e é colonizada pelas células germinativas, o que indica que estas continuam a receber o sinal adequado para a sua migração. Portanto, o SFI não está envolvido no desenvolvimento precoce da gônada e do sistema urogenital, mas parece estar envolvido na manutenção do crescimento das células somáticas presentes na gônada indiferenciada. O gene associado ao tumor de Wilms (WTI: Wilm's tumor Associated) está envolvido no desenvolvimento da gônada e do rim. Durante o desenvolvimento embrionário, WTI se expressa em todo o mesoderma intermediário e posteriormente na gônada indiferenciada, bem como no rim em formação. WTI regula o sinal indutivo do mesênquima para o epitélio celômico dos mesonefros. Se este for o caso, então WTI é responsável pelo crescimento da crista genital ao dirigir a entrada do epitélio celômico. Dado que estas células darão origem às células de Sertoli, a carência de WTI pode causar o desenvolvimento de embriões XY como fêmeas simplesmente porque não se formam as células de Sertoli. Em geral, todos os genes importantes na diferenciação do mesoderma intermediário e do sistema urogenital intervêm no desenvolvimento da gônada precoce. 1.4 DIFERENCIAÇÃO GONODAL O desenvolvimento das gônadas e ductos genitais descritos até o momento, é o mesmo para ambos os sexos. Igualmente, os genes descritos, que estão envolvidos no desenvolvimento das gônadas, ductos genitais e migração das células germinativas, afetam igualmente os embriões com genótipo XX ou XY. A gônada primitiva consiste anatomicamente de uma medula (interna) e uma crosta (externa), e de acordo com o local onde ocorre a colonização das células germinativas, diferenciara em testículo ou um ovário, respectivamente. Nos mamíferos, a primeira manifestação estrutural de diferenciação sexual é detectada na gônada dos machos, onde as células germinativas estão localizadas na medula. A diferenciação do testículo inicia-se quando os cordões sexuais se separam do epitélio celômico como consequência dos arranjos produzidos por uma invasão do mesênquima e vasos sanguíneos que provoca a compactação dos cordões, agora denominados cordões testiculares. As células que rodeiam os cordões se achatam e formam as células mioides, que são responsáveis pela formação das membranas basais. As células do epitélio interno, ou seja, as células de Sertoli, têm duas funções principais: o suporte das CGP e a síntese da hormona antimulleriana, responsável pela regressão dos ductos de Müller e secretada durante o período de diferenciação sexual. As células do estroma que rodeiam os cordões testiculares diferenciam-se para formar vários tipos de células: células mioides, fibroblastos, endotélio e células de Leydig, que são as mais importantes pela sua atividade endócrina. Posteriormente, os cordões testiculares dão origem aos túbulos seminíferos, que contêm o epitélio que produzirá os espermatozoides ao chegar à puberdade. Na fêmea, durante os estágios iniciais de diferenciação gonodal, não se observam mudanças em relação à gônada indiferenciada, só pode-se observar um certo crescimento devido à proliferação de células somáticas e germinativas. As células germinativas iniciam um período de proliferação, que termina com o início da meiose. Iniciada a meiose, dá-se o processo de foliculogênese; neste momento os cordões epiteliais se fragmentam, de tal maneira que cada ovócito fica rodeado de células epiteliais cobertas por uma folha basal fina (figura 1). Para que a gônada primitiva se desenvolva em testículo é indispensável a presença do cromossoma Y, independentemente do número de cromossomas X que contenha o genoma de um indivíduo. O gene determinante do testículo encontra-se localizado no cromossoma Y, denominado sry em ratos e SRY em humanos. O gene sry se expressa durante o desenvolvimento embrionário na crista genital de embriões de camundongos. A expressão é detectável no dia 10,5, pouco depois do aparecimento das cristas genitais, atinge o seu máximo durante o dia 11,5 e mantém-se até pouco depois de ocorrerem os primeiros sinais morfológicos de diferenciação testicular no dia 12,5. Este padrão de expressão é compatível com a teoria de que sry atua induzindo a ativação dos genes (figura 2) que conduzem ao desenvolvimento testicular, sem que exista a necessidade da expressão contínua de sry para manter a diferenciação do testículo após o dia 12,5. Como mencionado anteriormente, a gônada primitiva é composta por vários tipos de células. No entanto, as células germinativas primordiais não são o local de expressão do sry, já que os embriões que necessitam de células germinativas mantêm a expressão de sry e desenvolvem o sexo gonodal normalmente. As células somáticas na gônada em desenvolvimento incluem também as células de suporte. Sabe-se que é nestas células que o sry é expresso para que se diferenciem em células de Sertoli, e a expressão transitória de sry indica que deve ativar a outros genes para a manutenção das células de Sertoli. Uma vez diferenciadas as células de Sertoli, elas se encarregarão da diferenciação do resto das células na gônada. -/- Figura 1: Representação da diferenciação dos órgãos genitais internos. Adaptado de BRONSON, 1989. Figura 2: Cascada de genes envolvidos na diferenciação sexual, adaptado de KOOPMAN, 1999. O fator sry é necessário para a diferenciação do testículo. Embora não se conheçam os genes que provavelmente regulam esse gene, estudos realizados em camundongos demonstram que este gene parece coordenar-se com certos genes autossômicos. Entre estes genes autossômicos, o sox9, que é produzido pelas células de Sertoli uma vez que são estimuladas por sry, de modo que sox9 é um dos genes relacionados estruturalmente com sry. O Sox9 funciona como um fator de transcrição, mas não se sabe se a proteína tem qualquer outra função estrutural; este gene exprime-se abundantemente nos condrócitos e está relacionado com defeitos do aparelho ósseo chamados displasia campomélica. Curiosamente, os pacientes XY com esta condição sofrem frequentemente de reversão do sexo. O Sox9 é um dos poucos genes, além do SRY, do qual as mutações demonstraram interferir com a determinação sexual masculina. No entanto, apenas 75% dos pacientes com anomalias esqueléticas de tipo displasia campomélica têm reversão sexual e não foram encontrados casos de reversão sexual devido a um defeito de Sox9 que não seja acompanhado de defeitos esqueléticos. Isso indica que o Sox9 é apenas um membro da rede de genes que são ativados para determinar a diferenciação sexual, enquanto a rota que rege a condrogênese é mais sensível a perturbações deste. O momento em que se detecta a expressão do gene Sox9 (11dpc em ratos) coincide com a máxima expressão de sry, o que poderia indicar a possibilidade de que sry regule positivamente a Sox9. De fato, na região do promotor de Sox9 há um local de união ao que potencialmente se pode unir o sry. A expressão de Sox9 durante a diferenciação sexual sugere um papel abaixo de sry na diferenciação das células de Sertoli. O cromossoma X também é importante na diferenciação gonodal. O gene DAX-I foi isolado do lócus DSS (Dosage sensitive sex reversal) do cromossoma X. DAX-I é parte da cascata de determinação sexual, mas não é necessário para a formação do testículo. DAX-I é um membro dos receptores nucleares conhecidos como receptores órfãos. Este gene demonstrou ser um poderoso repressor da transcrição de SFI e de vários genes. Os padrões de expressão de DAX-I são complementares daqueles de SFI, ambos expressos nas cristas genitais. Em resumo, dada a evidência exposta, desenvolveu-se a hipótese de que DAX-I é um antagonista de sry; esse antagonismo é dependente dos níveis relativos de DAX-I e sry e de um limiar que varia de espécie para espécie. A DAX-I foi classificada como o gene antitestículo. Na fêmea (cariótipo XX) é importante que ocorra a inativação de um dos cromossomas sexuais X para que se mantenha o equilíbrio genético ao igualar o conteúdo de DNA dos cromossomas. Esse cromossoma inativado constitui o chamado corpúsculo de Barr. No entanto, para que a meiose se realize, é necessário dos dois cromossomas X ativos nos ovócitos para assegurar a diferenciação ovárica e a fertilidade. 1.5 DIFERENCIAÇÃO DOS DUCTOS SEXUAIS O embrião possui, além das gônadas indiferenciadas, dois sistemas de ductos: os de potencialidade masculina denominam-se ductos de Wolff ou mesonéfricos, e os de potencialidade feminina se chamam ductos de Müller ou paramesonéfricos (figura 1). Se a diferenciação gonodal levou à formação de um testículo, a partir do ducto mesonéfrico ou de Wolff se desenvolverão os ductos eferentes, o epidídimo, os ductos deferentes e as vesículas seminais. As hormonas importantes no desenvolvimento do aparelho genital masculino são a testosterona, produzida pelas células de Leydig, e sua forma 5α reduzida, a 5α di-hidrotestosterona. Acredita-se que a testosterona é responsável pela virilização dos ductos de Wolff, e a di-hidrotestosterona dos órgãos genitais externos. No macho, os canais de Müller atrofiam-se devido à ação de uma hormona fetal de origem testicular denominada hormona inibidora das estruturas de Müller (HIM) ou hormona antimulleriana. Este processo começa assim que os cordões espermáticos se formam e se diferenciam as células de Sertoli. A existência de HIM foi proposta baseada em estudos realizados em bezerras freemartin, devido à existência de uma hormona responsável pela atresia dos ductos de Müller que na fêmea dá origem ao útero e aos ovidutos. Essa hormona provoca a involução do aparelho genital do bovino nas gestações gemelares nas quais os produtos de diferente sexo têm comunicação sanguínea por ter ocorrido a anastomose dos vasos de ambas as placentas (figura 3). A HIM é uma glicoproteína pertencente à subfamília de TGFβ, é expressa pelas células que darão origem às células de Sertoli e é um dos primeiros marcadores de diferenciação nestas células. A HIM é secretada na vida adulta pelas células de Sertoli no testículo e por células da granulosa no ovário. No rato a HIM é expressa-se no 12° dia em um teste padrão que segue muito de perto o aumento na expressão de sry. No macho, esta secreção de HIM continua durante a vida fetal e adulta, contudo os níveis de HIM declinam na puberdade devido a um aumento na secreção de testosterona. Vários fatores intervêm na regulação do gene de HIM, incluindo os acima descritos SFI e Sox9. O gene HIM contém segmentos de DNA que são conservados em várias espécies de vertebrados. Existe um nexo de ligação para SFI, que ativa a transcrição de HIM. A mutação no local de ligação de SFI resulta em reversão do sexo em indivíduos XY incluindo genitais femininos normais, presença de um útero formado enfatizando a importância de SFI na determinação sexual e na expressão de HIM. Embora SFI seja um bom candidato como regulador de HIM, é expresso em outras células, como as de Leydig e adrenais, que não expressam HIM. Em contrapartida, Sox9 é expresso unicamente nas células de Sertoli que são as produtoras de HIM. O gene HIM também tem um nexo de ligação para Sox9. Além disso, Sox9 pode atuar sinergicamente com SFI para promover a secreção de HIM. Ao contrário destes dois fatores de transcrição, DAX-I antagoniza a ação de Sox9 e provavelmente SFI sobre o promotor de HIM. Assim, para que as células de Sertoli secretem HIM, a transcrição de DAX-I deve diminuir. Figura 3: Representação da diferenciação dos órgãos genitais externos. Adaptado de BRONSON, 1989. Os ductos de Wolff tornam-se o sistema de ejaculação do macho. A porção mais próxima dos testículos dá origem ao epidídimo, a parte central ao ducto deferente e a porção mais distal às vesículas seminais. A próstata e a parte membranosa da uretra do macho desenvolvem-se a partir da porção pélvica do seio urogenital. A virilização e diferenciação dos ductos de Wolff dependem da produção de testosterona pelo testículo. Quanto aos órgãos genitais externos do macho, o tubérculo genital é ampliado e as dobras uretrais se fundem para formar a uretra peniana. A fusão das dobras uretrais aproxima os tubérculos genitais para formar o escroto (figura 4). Figura 4: Diferenciação do aparelho genital da fêmea e do macho. Adaptado de KOOPMAN, 1989. A diferenciação dos órgãos genitais da fêmea ocorre de forma passiva, já que a ausência de testículos e por isso da hormona inibidora dos ductos de Müller (HIM), assim como dos andrógenos virilizantes, favorece o desenvolvimento dos ductos de Müller, enquanto os de Wolff sofrem atrofia. A porção cefálica dos ductos de Müller dá origem aos ovidutos, que na sua terminação caudal se fundem com o útero. O contato dos ductos de Müller com o seio urogenital induz uma intensa proliferação celular que resulta na formação da área uterovaginal localizado entre o seio urogenital e os ductos de Müller. As células do prato uterovaginal proliferam e aumentam a distância entre as duas estruturas criando o espaço que formará a vagina quando o prato é canalizado e forma um lúmen. Em contraste com o que ocorre no macho, na fêmea a maior parte do seio urogenital se mantém exposta na superfície da abertura onde desembocam a vagina e a uretra. O tubérculo urogenital da fêmea tem um crescimento limitado e forma o clitóris. A sequência de passos da diferenciação sexual do aparelho genital é resumida na tabela 1.

Assim, da mesma maneira que a gônada e os ductos sexuais se desenvolvem para o tipo feminino ou masculino, propôs-se que o cérebro pode ser "masculinizado" ou permanecer "Feminizado". A diferenciação do hipotálamo vai depender do ambiente esteroidal do neonato e ocorre na fase perinatal. Estes eventos serão de grande transcendência na vida reprodutiva do indivíduo. Tanto a fêmea como o macho nascem com a capacidade de secreção de gonadotropinas de acordo com um padrão cíclico; contudo, no macho, a exposição do hipotálamo à ação dos andrógenos testiculares durante os primeiros dias da vida extrauterina provoca a masculinização, com o qual o hipotálamo do macho é programado para que a secreção de gonadotropinas se realize a um ritmo relativamente constante por parte da hipófise (secreção tônica). Na fêmea, tanto a secreção tônica como a cíclica se conservam. No entanto, observou-se que a injeção de testosterona ou o transplante de testículo na rata fêmea durante os primeiros dias de vida, suprime a sua futura atividade estral (secreção cíclica). Por outro lado, se os ovários forem transplantados para o rato macho normal castrado na idade adulta, o animal não desenvolve qualquer atividade cíclica, mas se os machos transplantados forem castrados ao nascer, o ovário é capaz de efetuar mudanças cíclicas e ovulações. Isto foi demonstrado em roedores, mas não em animais domésticos ou na espécie humana. Portanto, o padrão de secreção de gonadotropinas, seja cíclico ou tônico, não depende da hipófise, mas do hipotálamo e sua correta diferenciação. 1.7 CONCLUSÕES A maioria dos conhecimentos no campo da biologia do desenvolvimento e, muito especificamente, dos processos de diferenciação sexual têm sido originados de estudos relacionados com desordens congênitas, que na sua maioria devem-se a defeitos de genes específicos. A análise detalhada destas desordens permitiu entender alguns mecanismos endócrinos, moleculares e genéticos envolvidos na diferenciação sexual. A identificação do gene sry como determinante do testículo foi uma contribuição crucial e abriu as portas à compreensão dos mecanismos moleculares e celulares relacionados com o desenvolvimento do testículo. Se este gene não estiver presente, é criado um programa genético alternativo para levar a cabo a diferenciação gonodal para o ovário. Finalmente, devemos ter presente que é necessária uma correlação entre mudanças morfológicas e expressão de genes durante o desenvolvimento para entender os mecanismos relacionados com a diferenciação. -/- Apoio -/- Realização -/- REFERÊNCIAS BIBLIOGRÁFICAS ANDERSON, Robert et al.

I denne artikel argumenteres der for, at døden i Phaidon primært skal forstås metaforisk, som sjælens adskillelse fra kroppen i den rene tænkning. Artiklens hovedtese er, at de fire argumenter for sjælens udødelighed, der findes i dialogen, skal læses som en fremadskridende afklaring af, hvilken væremåde sjælen har, når den isolerer sig fra kroppen, snarere end at læses bogstaveligt som beviser for, at sjælen er udødelig. Tillige argumenteres der for, at den såkaldt anden sejlads – Sokrates’ beskrivelse af, hvorledes han (...) for at forstå virkeligheden søgte tilflugt i argumenter og ideer snarere end i sanserne – skal forstås som et forsvar for en bestemt opfattelse af menneskelig frihed. Når Sokrates indfører ideerne som årsager i løbet af Phaidon, skal dette først og fremmest ses som en forklaring på, hvordan den rene tænkning kan erkende virkeligheden og derigennem kontrollere vores umiddelbare tilbøjeligheder. Det er mulighedsbetingelsen for menneskelig frihed som Platons Sokrates forstår den. Frihed skal da primært forstås som mulighed, nemlig mulighed til at handle i overensstemmelse med det, den fornuftsbestemte indsigt tilsiger en, at man skal gøre, uden hensyntagen til umiddelbare, kropsligt bestemte tilbøjeligheder, herunder tilbøjeligheden til selvopretholdelse for enhver pris. Den foreslåede læsning peger dermed på en politisk dimension af Phaidon, der ofte overses som følge af, at argumenterne for sjælens udødelighed tages for bogstaveligt. (shrink)

This volume offers a collective study of the work of P. F. Strawson (1919-2006) and an exploration of its relevance for current philosophical debates. It is the first book since Strawson's death to cover the full range of his philosophy, with chapters by world-leading experts about his lasting contributions to the philosophy of language, metaphysics, epistemology, moral philosophy, and philosophical methodology. It aims to achieve a balance between exegesis of Strawson, critical engagement, and consideration of the reception and continuing value (...) of his work. It explores the intellectual relations between Strawson and some of his predecessors and contemporaries and it will be an indispensable source for scholars and students of twentieth-century philosophy and its influence in the twenty-first. With contributions by Anne Bezuidenhout, Ian Rumfitt, Paul Snowdon, Quassim Cassam, Michelle Montague, Hans-Johann Glock, Anil Gomes, Lilian Alweiss, Giuseppina D'Oro, A.P. Martinich, Paul Russell, Lucy Allais, and Victoria McGeer. (shrink)

El presente trabajo de tesis se centra en el estoicismo, en la obra titulada Disertaciones que recoge las enseñanzas de Epicteto pero que fue recopilada por Arriano. Es en tal texto en el que principalmente basamos la presente tesis. Analizamos las enseñanzas de Epicteto, filósofo nacido en Hierópolis (Frigia) hacia el 55 d.C., que fue un liberto que se adentró en el estoicismo tras asistir a las clases del filósofo Musonio Rufo; gracias al permiso de su amo Epafrodito pudo asistir (...) a las pláticas de tal erudito. Los dos temas a tratar, el poder y el amor, que forman parte de la ética y de la filosofía política –estoicas-, así como de la epistemología, la física y la metafísica, por ser el sistema estoico uno que está estrecha y racionalmente interconectado, han sido abordados por investigadores recientes desde distintos ámbitos y perspectivas. El poder y el amor son conceptos que deben de ser explicados y analizados a partir de los conceptos mencionados de “sentimiento”, “inclinación”, “pasión”, “bueno”, “malo”, además de los de “virtud”, “vicio”, “indiferente”, “oikéiosis”, “deber”, “sabio”, “libertad”, etc. Por lo que ambas categorías han sido abordadas desde su vinculación con, o a partir de su explicación a través de, uno o varios de los conceptos mencionados.

TWENTIETH-CENTURY ETHICS. AFTER NIETZSCHE -/- Preface This book tells the story of twentieth-century ethics or, in more detail, it reconstructs the history of a discussion on the foundations of ethics which had a start with Nietzsche and Sidgwick, the leading proponents of late-nineteenth-century moral scepticism. During the first half of the century, the prevailing trends tended to exclude the possibility of normative ethics. On the Continent, the trend was to transform ethics into a philosophy of existence whose self-appointed task was (...) that of describing the human condition as consisting of choices, as unavoidable as arbitrary, without any attempt at providing criteria for making such choices. In the Anglo-Saxon countries, the heir of ethics was a philosophy of morality, that is, an analysis of the language of morality that intended to clarify valuations without trying to justify them. 1958 was the year of the normative turn that led to the Rehabilitation of practical philosophy, a turn followed by decades of controversies between distinct kinds of normative ethics: utilitarian, Kantian, virtue ethics. While the controversy was raging, a quiet revolution took place, that of applied ethics which surprisingly dissolved the controversy's very subject matter by providing methods for making convergence possible on intermediate principles even when no agreement was available about first principles. The normative turn and the revolution of applied ethics have led us, at the turn of the century, to a goal that was quite far from the starting point. Instead of scepticism and relativism that was the fashion at the beginning of the century, at the beginning of the third millennium impartial and universal moral arguments seem to hold the spot being supported, if not by a final rational foundation, at least by reasonableness, the most precious legacy of the Enlightenment. -/- ● TABLE OF CONTENTS -/- ● I Anglo-Saxon philosophy: naturalism 1. Dewey beyond evolutionism and utilitarianism 2. Dewey and anti-essentialist moral epistemology 3. Dewey and naturalist moral ontology 4. Dewey and normative ethics of conduct and function 5. Perry and semantic naturalism -/- ● II Anglo-Saxon philosophy: ideal utilitarianism and neo-intuitionism 1. Moore's critique of utilitarian empiricism 2. Moore on the naturalistic fallacy 3. Moore on the nature of intrinsic value 4. Moore on ideal utilitarianism 5. Prichard on the priority of the right over the good 6. Ross's coherentist moral epistemology 7. Ross's moral ontology: realism, pluralism, and non-naturalism 8. Ross's normative ethics of prima facie duties -/- The chapter reconstructs the background of ideas, concerns and intentions out of which Moore's early essays, the preliminary version, and then the final version of Principia Ethica originated. It stresses the role of religious concerns, as well as that of the Idealist legacy. It argues that PE is more a patchwork of somewhat diverging contributions than a unitary work, not to say the paradigm of a new school in Ethics. -/- ●III Anglo-Saxon philosophy: non-cognitivism 1. The Scandinavian School, the Vienna circle and proto-emotivism 2. Wittgenstein and the ineffability of ethics 3. Russell's and Ayer's radical emotivism 4. Stevenson and moderate emotivism 5. Stevenson and the pragmatics of moral language 6. Stevenson and the methods for solving ethical disagreement 7. Hare and prescriptivism The chapter reconstructs first the discussion after Moore. The naturalistic-fallacy argument was widely accepted but twisted to prove instead that the intuitive character of the definition of 'good', its non-cognitive meaning, in a first phase identified with 'emotive' meaning. Alfred Julius Ayer is indicated as a typical proponent of such non-cognitivist meta-ethics. More detailed discussion is dedicated to Bertrand Russell's ethics, a more nuanced and sophisticated doctrine, arguing that non-cognitivism does not condemn morality to arbitrariness and that the project of rational normative ethics is still possible, heading finally to the justification of a kind of non-hedonist utilitarianism. Stevenson's theory, another moderate version of emotivism is discussed at some length, showing how the author comes close to the discovery of the role of a pragmatic dimension of language as a basis for ethical argument. A section reconstructs the discussion from the Forties about Hume's law, mentioning Karl Popper's argument and Richard Hare's early non-cognitivist but non-emotivist doctrine named prescriptivism. -/- ●IV Anglo-Saxon philosophy: critics of non-cognitivism 1. Neo-naturalism and its objections to the naturalistic fallacy argument 2. Objections to Hume's law 3. Clarence Lewis and the pragmatic contradiction 4. Toulmin and the good reasons approach 5. Baier and moral reasons 5. Baier, social moralities and the absolute morality 6. Baier and the moral point of view 7. Baier and the contents of absolute ethics -/- ● V Continental philosophy: the philosophy of values 1. Max Weber and the polytheism of values 2. Phenomenology against psychologism and rationalism 3. Reinach and the theory of social acts 4. Scheler and the material ethics of values 5. Hartmann and the ontology of values 6. Plessner, Gehlen and the Philosophische Anthropologie -/- The chapter illustrates first the idea of phenomenology and the Husserl's project of a phenomenological ethic as illustrated in his 1908-1914 lectures. The key idea is dismissing psychology and trying to ground a new science of the apriori of action, within which a more restricted field of inquiry will be the science of right actions. Then the chapter illustrates the criticism of modern moral philosophy conducted in the 1920 lectures, where the main target is naturalism, understood in the Kantian meaning of primacy of common sense. The third point illustrate is Adolph Reinach's theory of social acts as a key the grounding of norms, a view that sketches the ideas 'discovered' later by Clarence I. Lewis, John Searle, Karl-Otto Apel and Jürgen Habermas. A final section discusses Nicolai Hartman, who always refused to define himself a phenomenologist and yet developed a more articulated and detailed theory of 'values' – with surprising affinities with George E. Moore - than philosophers such as Max Scheler, who claimed to be Husserl's legitimate heirs. -/- ● VI Continental philosophy: the critics of the philosophy of values 1. Freud, the Superego and Civilization 2. Heidegger on original ethos against ethics 3. Sartre and de Beauvoir on authenticity and ambiguity 4. Adorno and Horkheimer on emancipation and immoralism -/- ●VII Post-liberal theologians and religious thinkers 1. Barth on the autonomy of faith from ethics 2. Developments of Reformed moral theology after Barth 3. Bonhoeffer on the concrete divine command and ethics of penultimate realities 4. Developments of Reformed and Catholic moral theology after world war II 5. Baeck and the transformation of liberal Judaism 6. Rosenzweig against liberal Judaism 7. Buber and religion as the vital lymph of morality 8. Heschel and Judaism as a science of actions -/- The chapter examines the main protagonists of Christian theology and Jewish religious thinking in the twentieth century. It stresses how the main dilemmas of contemporary philosophical ethics lie at the root of the various path of inquiry taken by these thinkers. -/- ● VIII Normative ethics: neo-Utilitarianism 1. The discussion on act and rule utilitarianism 2. Hare on two-tiered preference utilitarianism 3. Harsanyi, Gauthier and rational choice ethics 4. Parfit, utilitarianism and the idea of a person 5. Brandt and indirect conscience utilitarianism -/- The chapter addresses the issue of the complex process of self-transformation Utilitarianism underwent after Sidgwick's and Moore's fatal criticism and the unexpected Phoenix-like process of rebirth of a doctrine refuted. Two examples give the reader a glimpse at this uproarious process. The first is Roy Harrod Wittgensteinian transformation of utilitarianism in pure normative ethics depurated from hedonism as well as from whatsoever theory of the good. This transformation results in preference utilitarianism combined with a 'Kantian' version of rule utilitarianism. The second is Richard Hare's two-level preference utilitarianism, where act utilitarianism plays the function of the eventual rational justification of moral judgments and rule-utilitarianism that of an action-guiding practical device. -/- ● IX Normative ethics: neo-Aristotelianism and virtue ethics 1. Hannah Arendt, action and judgement 2. Hans-Georg Gadamer and phronesis 3. Alasdair MacIntyre on practices, virtues, and traditions 5. Stuart Hampshire on deliberation 6. Bernard Williams and moral complexity 7. Feminist ethics -/- Sect 1 reconstructs the post-war rediscovery of ethics by many German thinkers and its culmination in the Sixties in the movement named 'Rehabilitation of practical philosophy' is described. Heidegger's most brilliant disciples were the promoters of this Rehabilitation. Hans-Georg Gadamer is a paradigmatic example. His reading of Aristotle's lesson I reconstructed, starting with Heidegger's lesson but then subtly subverting its outcome thanks to the recovery of the significant role of the notion of phronesis. Sect 3 discusses the three theses defended by Anscombe in 'Modern Moral Philosophy'. It argues that: a) her answer to the question "why should I be moral?" requires a solution of the problem of theodicy, and ignores any attempts to save the moral point of view without recourse to divine retribution; b) her notion of divine law is an odd one more neo-Augustinian than Biblical or Scholastic; c) her image of Kantian ethics and intuitionism is the impoverished image manufactured by consequentialist opponents for polemical purposes and that she seems strangely accept it; d) the difficulty of identifying the "relevant descriptions" of acts is not an argument in favour of an ethics of virtue and against consequentialism or Kantian ethics, and indeed the role of judgment in the latter is a response to the difficulties raised by the case of judgment concerning future action. The chapter gives a short look at further developments in the neo-naturalist current trough a reconstruction of Philippa Foot's and Peter Geach's critiques to the naturalist-fallacy argument and Alasdair MacIntyre's grand reconstruction of the origins and allegedly inevitable failure of the Enlightenment project of an autonomous ethic. -/- ● X Normative ethics: Kantian and rights-based ethics 1. Dialogical constructivism 2. Apel, Habermas and discourse ethics 3. Gewirth and rights-based ethics 4. Nagel on agent-relative reasons 5. Donagan and persons as ends in themselves Parallel to the neo-Aristotelian trend, there was in the Rehabilitation of practical philosophy a Kantian current. This current started with the discovery of the pragmatic dimension of language carried out by Charles Peirce and the Oxford linguistic philosophy. On this basis, Karl-Otto Apel singled out as the decisive proponent of the linguistic and Kantian turn in German-speaking ethics, worked out the performative-contradiction argument while claiming that this was able to provide a new rational and universal basis for normative ethics. The chapter offers an examination of his argument in some detail, followed by a more cursory reconstruction of Jürgen Habermas's elaboration on Apel's theory. -/- ● XI The applied ethics renaissance 1. Elisabeth Anscombe on the atom bomb 2. From medical ethics to bioethics 3. Rawls and public ethics 3. Nozick, Dworkin and further developments of public ethics 5. Sen and the revival of economic ethics -/- The chapter presents the revolution of applied ethics while stressing its methodological novelty, exemplified primarily by Beauchamp and Childress principles approach and then by Jonsen and Toulmin's new casuistry. The chapter argues that Rawls's distinction between a "political" and a "metaphysical" approach to the theory of justice, one central part of ethical theory, is a formulation of the same basic idea at the root of both the principles approach and the new casuistry, both discussed in the following chapter. The idea is that it is possible to reach an agreement concerning positive moral judgments even though the discussion is still open – and in Rawls' view never will be close – on the essential criteria for judgment. -/- ● XII Fin-de-siècle metaethics 1. Deontic logics 2. Anti-realism 3. External realism 4. Internal realism 5. Kantian constructivism -/- The chapter illustrates the fresh start of meta-ethical discussion in the Eighties and Nineties and the resulting new alignments: metaphysical naturalism, internal realism, anti-realism, and constructivism.

Karl Popper, en tant que rationaliste critique, a été un opposant à toutes les formes de scepticisme, de conventionnalisme et de relativisme scientifique. En 1935, il a écrit Logik der Forschung. Zur Erkenntnistheorie der modernen Naturwissenschaft, traduisant plus tard le livre en anglais et le publiant sous le titre The Logic of Scientific Discovery (1959), considéré comme un travail de pionnier dans son domaine. De nombreux arguments de ce livre sont dirigés contre les membres du « Cercle de Vienne », (...) tels que Moritz Schlick, Otto Neurath, Rudolph Carnap, Hans Reichenbach, Carl Hempel et Herbert Feigl. Popper est d'accord avec eux sur les aspects généraux de la méthodologie scientifique et sur leur méfiance à l'égard de la méthodologie philosophique traditionnelle, mais ses solutions ont été sensiblement différentes. Popper a largement contribué aux débats sur la méthodologie scientifique générale, la démarcation de la pseudo-science, la nature des probabilités et la méthodologie des sciences sociales.

Historically, laws and policies to criminalize drug use or possession were rooted in explicit racism, and they continue to wreak havoc on certain racialized communities. We are a group of bioethicists, drug experts, legal scholars, criminal justice researchers, sociologists, psychologists, and other allied professionals who have come together in support of a policy proposal that is evidence-based and ethically recommended. We call for the immediate decriminalization of all so-called recreational drugs and, ultimately, for their timely and appropriate legal regulation. We (...) also call for criminal convictions for nonviolent offenses pertaining to the use or possession of small quantities of such drugs to be expunged, and for those currently serving time for these offenses to be released. In effect, we call for an end to the “war on drugs.”. (shrink)

The Louvre Museum is the largest of the world's art museums by its exhibition surface. These represent the Western art of the Middle Ages in 1848, those of the ancient civilizations that preceded and influenced it (Oriental, Egyptian, Greek, Etruscan and Roman), and the arts of early Christians and Islam. At the origin of the Louvre existed a castle, built by King Philip Augustus in 1190, and occupying the southwest quarter of the current Cour Carrée. In 1594, Henri IV decided (...) to unite the palace of the Louvre with the palace of the Tuileries built by Catherine de Medicis. The Cour Carrée was built by the architects Lemercier and then Le Vau, under the reign of Louis XIII and Louis XIV. The Department of Paintings currently has about 7,500 paintings (of which 3,400 are exposed), covering a period that goes from the Middle Ages to 1848 (date of the beginning of the Second Republic). By including the deposits, the collection is, with 12,660 works, the largest collection of ancient paintings in the world. With rare exceptions, the works after 1848 were transferred to the Musée d'Orsay when it was created in 1986.

This study is about the Quality. Here I have dealt with the quality that differs significantly from the common understanding of quality /as determined quality/ that arise from the law of dialectics. This new quality is the quality of the quantity /quality of the quantitative changes/, noticed in philosophy by Plato as “quality of numbers”, and later developed by Hegel as “qualitative quantity. The difference between the known determined quality and qualitative quantity is evident in the exhibit form of these (...) two qualities. The exhibit form of the known determined quality from the law of dialectics /or it transformation/ is related with discreteness and abrupt changes. The exhibit form of the qualitative quantity /and it transformation/ is related with the continuity and gradual transition from one condition, to a different condition, without any abrupt changes. In my paper “Quality of the quantity”, I have argued that one of the most ancient implementation of quality of the number can be found in the dimensional mathematical model of point – line – surface – figure - introduced by Plato. The most whole presentation of the idea of quality of number in Plato is embeded in his teaching about the "eidical number". The quality of the quantity emerges as criteria for recognizing the difference between the eidical numbers and natural arithmetical number. The thesis concerning Plato is based on the The Unwritten Doctrine of Plato and one of the most original works in the history of philosophy written in the 20th century - “Arete bei Platon und Aristoteles” – “Arete in Plato and Aristotle” /Heidelberg 1959/ written by Hans Joachim Krämer. The new quality as the quality of the quantity /quality of the quantitative changes/, first noticed in philosophy by Plato as “quality of numbers” was developed in Hegel as “qualitative quantity”. Hegel proclaimed the Qualitative quantity, or Measure in the both of his Logics -The Science of Logic / the Greater Logic/ and The Lesser Logic/ Part One of the Encyclopedia of Philosophical Sciences: The Logic. In my paper I have offered the arguments that the concept of quality of the quantity should be enhanced with the adopted methodological approach of analogy with an implementation in the field of the Topology - Analysis Situs, developed by the Jules Henri Poincare. In the topology we could see homeomorphism as exhibit form of Quality on the Quantity. The explicit form of the quality of the quantity transformation is the continuous deformation – typically known in topology as homeomorphism. The concept of qualitative quantity is linked with the concept “structural stability” and nonequilibrum phase transition. The concept of structural stability is related with the topological homeomorphism. In his book “Synergetics: Introduction and Advanced Topics” /Springer, ISBN 3-540-40824/, in the Chapter 1.13. Qualitative Changes: General approach, p. 434-435, Hermann Haken explores and illustrate the structural stability with an example /figure 1.13, p.434/ given by of D'Arcy W. Thompson, the Scottish biologist, mathematician and classics scholar and pioneering mathematical biologist, Nobel Laureate in Medicine /1960/, the author of the book, On Growth and Form, /1917/. The quality of the quantity could be seen in the Herman Haken’s citation on the D'Arcy W. Thompson. My thesis is that the topological homeomorphism is the explicit form of the quality of the quantity transformation. The qualitative quantity change which becomes phenomenon, according to Émile Boutroux, is the subject of study in Cultural Phenomenology of Qualitative quantity. Our approach to this subject is Poincaré Model of the Subconscious Mind in Mathematics, which is the most suitable tool to unfold the arhetype of qualitative quantity. (shrink)

Les diferents filosofies “postmodernes” que sorgiren dels anys 1970 als anys 1990 s'han considerat sovint com una classe d´“ideología” irracionalista-escèptica-relativista (o alguna altra sort d´amalgama semblant) que en el nostre temps prendrien perillosament el control sobre la filosofia acadèmica i la cultura occidental, amb greu risc per als universalistes o, simplement, per a qualsevol projecte racionalista.2 No obstant això, com el títol d'aquest article denota, un examen més detallat d'algunes tendències del pensament postmodern podria mostrar no solament que algunes d´aquestes (...) filosofies estan incòmodes amb l'etiqueta “relativista”, “irracionalista” o “escèptica”, sinó també que ofereixen arguments substancials en contra, per exemple, de les tesis principals del relativisme. Nogensmenys, naturalment, cap d´aquestes tendències deixa de tenir també famoses reserves respecte del universalisme (el suposat enemic mortal dels relativistes). (shrink)

En aquest article es presenten dues teories sobre la naturalesa del temps i s’analitzen objeccions que s’hi han presentat els darrers anys en el marc de la filosofia analítica. La primera sosté que el passat i el futur no són reals, i presenta el problema de com es poden expressar proposicions veritables sobre temps no presents. D’acord amb la segona teoria, per contra, tots els temps —present, passat i futur— són igual de reals, però això sembla implicar que el futur (...) sigui tan determinat i inexorable com el passat... L’autor clou amb una reflexió entorn de la manera de fer de la filosofia analítica i dels horitzons d’aquesta tradició. (shrink)

This paper engages critically with anti-representationalist arguments pressed by prominent enactivists and their allies. The arguments in question are meant to show that the “as-such” and “job-description” problems constitute insurmountable challenges to causal-informational theories of mental content. In response to these challenges, a positive account of what makes a physical or computational structure a mental representation is proposed; the positive account is inspired partly by Dretske’s views about content and partly by the role of mental representations in contemporary cognitive scientific (...) modeling.
