How the cilium appeared is still such a poorly defined question that current hypotheses range from a symbiotic spirochaete to a cellular eye. In this paper, the whole question is subdivided into a list of problems which are morphological, physiological and temporal. These problems are examined one by one, in order to analyse the most popular exogenous hypothesis of Margulis as well as other recent exogenous and endogenous hypotheses. To overcome fundamental topological and temporal difficulties, a new endogenous hypothesis is (...) expounded, according to which the cilium derives from a cellular peduncle reinforced with microtubules. This hypothesis implies a geometrical rationale for the ninefold symmetry. In the last paragraph the consequences of the various hypotheses are compared. (shrink)

As colleges and universities seek to invigorate ethics education, they need methods to identify where and describe how ethics is already present across their curricula. Meeting this need is complicated by the fact that much ethics education occurs in courses not explicitly focused on ethics or morality. In this paper, we review recent methodological advances before presenting a new Ethics Course Identification Tool (ECIT) that combines application of an expert-derived weighted dictionary and natural language processing methods to identify ethics-related courses (...) based on their titles and course catalog descriptions, even when the terms “ethic” or “moral” are not present. Two studies, the second a pre-registered replication, revealed considerable interrater reliability among experts in ethics education regarding the ethical relevance of courses. Critically, both studies revealed strong correlations between expert judgments and ECIT scores. This empirical evidence points to a shared understanding of ethics education among experts, and it supports the valid use of the ECIT to rapidly and reliably identify ethics-related courses. Based on these findings, we propose that the ECIT can be used both to advance research on trends in ethics education and to help target interventions to improve ethics education at colleges and universities.

The aim of this article is to highlight and discuss two problems of the biological philosophy of technology. In particular, I will analyse the work of André Leroi-Gourhan and Gilbert Simondon, and I will show that the meaning of the analogy between technical and natural objects that underlies the approach of the biological philosophy of technology remains problematic and the biological approach to technology is very effective for analysing tools and machines, but is not sufficient to describe the so-called information (...) technologies. In the last part of the article, I will argue that, in order to understand information technologies, it is necessary to integrate the biological approach to technology with a grammatological approach. I will try to show that, next to the tool and the machine, there is a third category of technical objects that can be better described using the notion of “writing” proposed by one of the masters of the so-called French Thought, Jacques Derrida.

En el último mes los practicantes de yoga que habitan la ciudad de Washington se han enfrentado con una situación que pone sobre el tapete la definición misma de su práctica. El primero de Octubre pasado, en efecto, ha entrado en vigencia una nueva legislación por la cual a los establecimientos cuya finalidad es el ejercicio físico, tales como gimnasios, centros de fitness y también, de acuerdo con las autoridades impositivas, institutos de Yoga, se les cobra casi un 6% de (...) impuesto sobre las ganancias. Tal medida ha desatado, posiblemente sin buscarlo, una polémica de corte filosófico. Los practicantes, por una parte, abogan por el rechazo de la aplicación del "yoga tax" o impuesto del yoga, como ha pasado a llamarse, sobre su práctica. Alegan, para ello, que la finalidad del yoga es "integrar la mente, el cuerpo y el espíritu" y afirman que la mejora en el estado físico es un efecto secundario. Las autoridades, por otra parte, son taxativas en su visión del yoga como un ejercicio y no están dispuestas a flexibilizar sus criterios. (shrink)

Erleichtert die Konzeptualisierung der Patientenverfügung als bloßes Indiz für den mutmaßlichen Willen die notwendige Einbeziehung eines relationalen Autonomieverständnisses in eine zunehmend kulturübergreifende Bioethik? Ich lege dar, dass die Berücksichtigung relationaler Autonomiekonzepte kein überzeugendes Argument für die Bestimmung der Patientenverfügung als bloßes Indiz für den mutmaßlichen Willen ist, sondern vielmehr – neben einer Reihe anderer Argumente – für die Patientenverfügung als verbindliche Willensbekundung spricht. Diese erweist sich als flexibel genug, um unterschiedlichen Formen von Autonomie gerecht zu werden.

Who or what is morally considerable? That is to say, what merits direct moral consideration—consideration in light of what it is? Mark Bernstein steers a middle course between the extremes he labels “chauvinism” and “deep ecology.” Chauvinists hold that, at most, all human beings are morally considerable. Deep ecologists are either individualists who hold that every living thing is morally considerable or holists who hold that ecosystems but not their constituent parts are considerable in themselves.

A noção de “interesse público” parece ter uma tradição antiga e profícua nos estudos políticos, em particular nas pesquisas sobre mídia, comunicação e política. No entanto, parece haver um aparente paradoxo entre a própria noção de “interesse” e a ideia de algo “público”: como uma ação ou decisão política pode contemplar a miríade de interesses de grupos e indivíduos diversos? Este artigo delineia alguns aspectos da noção de “interesse” no debate atual sobre comunicação política. Com base em uma pesquisa bibliográfica, (...) este artigo argumenta que, nas últimas décadas, as principais obras sobre o tema têm dedicado menos espaço à noção de 'interesse público' como uma entidade única em favor de uma visão mais nuançada e identitária cultural, noção que contempla a pluralidade de uma esfera pública repleta de novas formas de ativismo e demandas coletivas por espaço, igualdade e visibilidade.

Brouwer's theorem of 1927 on the equivalence between virtual and inextensible order is discussed. Several commentators considered the theorem at issue as problematic in various ways. Brouwer himself, at a certain time, believed to have found a very simple counter-example to his theorem. In some later publications, however, he stated the theorem in the original form again. It is argued that the source of all criticisms is Brouwer's overly elliptical formulation of the definition of inextensible order, as well as a (...) certain ambiguity in his terminology. Once these drawbacks are removed, his proof goes through. (shrink)

La tesi che vorrei discutere in questo saggio può essere sintetizzata nel modo seguente: l'aspetto più significativo dell'intermedialità è legato al suo potenziale di riqualificazione del rapporto tra immagine e realtà. Intendo analizzare questa tesi facendo riferimento alla teoria estetica fenomenologica. La mia ipotesi è che vi sia una relazione essenziale tra i processi di obbiettivazione dell'esperienza intuitiva descritti da Husserl e le strategie di elaborazione intermediale dell'immagine. L'intermedialità può produrre effetti di autenticazione dell'immagine perché interviene su quelle dinamiche di (...) costituzione della realtà che sono più originarie dal punto di vista fenomenologico.Procederò dunque come segue: in primo luogo farò riferimento a due testi fondamentali di Husserl in cui vengono stabilite le linee guida di una estetica fenomenologica, Le lezioni sulla sintesi passiva e il secondo libro delle Idee. Nel rileggere questi due testi, così inesauribili, mi soffermerò esclusivamente sul problema della costituzione, attraverso l'esperienza percettiva, della realtà del percepito. In secondo luogo analizzerò la nozione di intermedialità, mettendola in relazione con le analisi fenomenologiche sviluppate a partire da Husserl. In Italia è stato Pietro Montani a proporre con forza l'idea di una connessione tra il problema delle «prestazioni referenziali» dell'immagine e l'intermedialità. Cercherò dunque di ricostruire alcuni passaggi fondamentali del suo discorso teorico facendo riferimento in modo particolare al libro L'immaginazione intermediale. Infine rischierò una esemplificazione concreta proponendo una lettura di un breve film di Iñárritu in cui il nesso tra intermedialità e realtà delle immagini è «messo in opera» in modo esemplare.

In section 1 we argue that the adoption of a tenseless notion of truth entails a realistic view of propositions and provability. This view, in turn, opens the way to the intelligibility of theclassical meaning of the logical constants, and consequently is incompatible with the antirealism of orthodox intuitionism. In section 2 we show how what we call the potential intuitionistic meaning of the logical constants can be defined, on the one hand, by means of the notion of atemporal provability (...) and, on the other, by means of the operator K of epistemic logic. Intuitionistic logic, as reconstructed within this perspective, turns out to be a part of epistemic logic, so that it loses its traditional foundational role, antithetic to that of classical logic. In section 3 we uphold the view that certain consequences of the adoption of atemporal notion of truth, despite their apparent oddity, are quite acceptable from an antirealist point of view.

This study presents the Italian adaptation of the Measure of Moral Orientation, second revision. Based on Carol Gilligan’s theory of the Ethics of Care, the MMO-2 was designed to measure two complementary moral stances, namely, Care and Justice. For this study, questionnaire responses from 683 university students were assessed against an Italian-adapted MMO-2 scale. Data were analyzed through exploratory structural equation modeling first as separate scenarios and then as a single model. The final model comprises 4 intercorrelated pairs of latent (...) variables and shows highly satisfactory goodness of fit indices with moderate construct validity and reliability. Strengths, limitations, and directions for the future developments of the MMO-2 are discussed. (shrink)

Dans les Essais hérétiques sur la philosophie de l’histoire, testament philosophique et spirituel de Jan Patočka, nous ne trouvons pas seulement, en dépit du titre, une philosophie de l’histoire, avec l’appel vibrant à notre responsabilité d’hommes « historiques » dans l’époque de la civilisation technique et de l’état de guerre permanent. Nous y trouvons aussi, ou peut-être surtout, bien que cela ne soit pas généralement examiné, la tentative d’élaborer une véritable généalogie de l’histoire...

At the end of the eighteenth century and beginning of the 19th, Spain and the Italian States contributed to the development of European agricultural science and the improvement of manufacturing. They collaborated with each other and reworked the most advanced models of France, Central Europe and Great Britain. Despite their somewhat less prosperous economic status, they demonstrated great originality in research and experimentation. In this process, botanical knowledge served as a starting point for a new epistemological path. Through three case (...) studies – the botanists Antonio José Cavanilles and Domenico Nocca, and the agriculturist Filippo Re – my article analyses how Spanish and Italian naturalists and learned individuals contributed to forming the concept of ‘economic botany’ through the exchange of seeds, plant specimens, books, journals, and – more in general – opinions, becoming germinal forces in a large transnational network.

The epistemological problem of the truth of memory cannot be resolved without establishing a clear distinction between recollection and phantasy. Husserl’s position in this regard is both paradoxical and compelling. It is paradoxical because Husserl repeats his antiskeptical intention many times; but nevertheless in his phenomenology, recollection and phantasy are almost completely identical. Perhaps no philosopher has so radically approached the experience of remembering and the experience of fantasizing as Husserl. But at the same time, the recognition of this fundamental (...) similarity is precisely what allows the phenomenologist to avoid empiricist misunderstandings and thus approach the problem of the distinction between recollection and phantasy in a much more persuasive way than the traditional one. In this paper, I will first try to show how and why Husserl approaches recollection and phantasy. Then I will try to show how it is possible to establish a clear distinction between these two phenomena without misunderstanding the possibility of false memory. (shrink)

Why is it so important to study Nietzsche? Many works about Nietzsche’s thought have been published over the years, from every conceivable position, including analytical philosophy.1 One more essay on Nietzsche may seem a bit repetitive. Yet, as Giuseppe Fornari wrote in the preface of Il Caso Nietzsche (The Nietzsche Case), it is fundamental to analyze Nietzsche deeply, because the most important themes of his works are still hidden among the pages of his books.2 René Girard has made an original (...) contribution to understanding Nietzsche by underlining the close connections between Nietzsche’s philosophy and the personal relationships he established during his life. In particular, Girard’s .. (shrink)

Obiettivo di questo intervento è indagare due soglie della soggettività: l’infanzia e l’animalità. Bambini e animali condividono il loro essere “assoggettati”: mentre l’adulto è soggetto tout court, il bambino lo deve ancora diventare e l’animale è trattato come polo opposto alla soggettività. Il punto di partenza è la domanda “che cosa è un bambino?”; apertamente socratica, questa domanda serve a incrinare i sedimenti di sapere depositatisi sul senso comune circa la “vera natura” del soggetto.

We introduce an epistemic version of validity and completeness of first order logic, based on the notions of ideal agent and fictional model. We then show how the perspective here considered may help to solve an epistemic puzzle arising from Gödel's second incompleteness theorem.

Leg rigidity is associated with frequent falls in people with Parkinson’s disease, suggesting a potential role in functional balance and gait impairments. Changes in the neural state due to secondary tasks, e.g., activation maneuvers, can exacerbate rigidity, possibly increasing the risk of falls. However, the subjective interpretation and coarse classification of the standard clinical rigidity scale has prohibited the systematic, objective assessment of resting and activated leg rigidity. The pendulum test is an objective diagnostic method that we hypothesized would be (...) sensitive enough to characterize resting and activated leg rigidity. We recorded kinematic data and electromyographic signals from rectus femoris and biceps femoris during the pendulum test in 15 individuals with PD, spanning a range of leg rigidity severity. From the recorded data of leg swing kinematics, we measured biomechanical outcomes including first swing excursion, first extension peak, number and duration of the oscillations, resting angle, relaxation index, maximum and minimum angular velocity. We examined associations between biomechanical outcomes and clinical leg rigidity score. We evaluated the effect of increasing rigidity through activation maneuvers on biomechanical outcomes. Finally, we assessed whether either biomechanical outcomes or changes in outcomes with activation were associated with a fall history. Our results suggest that the biomechanical assessment of the pendulum test can objectively quantify parkinsonian leg rigidity. We found that the presence of high rigidity during clinical exam significantly impacted biomechanical outcomes, i.e., first extension peak, number of oscillations, relaxation index, and maximum angular velocity. No differences in the effect of activation maneuvers between groups with clinically assessed low rigidity were observed, suggesting that activated rigidity may be independent of resting rigidity and should be scored as independent variables. Moreover, we found that fall history was more common among people whose rigidity was increased with a secondary task, as measured by biomechanical outcomes. We conclude that different mechanisms contributing to resting and activated rigidity may play an important yet unexplored functional role in balance impairments. The pendulum test may contribute to a better understanding of fundamental mechanisms underlying motor symptoms in PD, evaluating the efficacy of treatments, and predicting the risk of falls. (shrink)
