Optical distortions as a visual disturbance are inherent in many optical devices such as spectacles or virtual reality headsets. In such devices, distortions vary spatially across the visual field. In progressive addition lenses, for example, the left and right regions of the lens skew the peripheral parts of the wearers visual field in opposing directions. The human visual system adapts to homogeneous distortions and the respective aftereffects are transferred to non-retinotopic locations. This study investigates simultaneous adaptation to two opposing distortions (...) at different retinotopic locations. Two oppositely skewed natural image sequences were presented to 10 subjects as adaptation stimuli at two distinct locations in the visual field. To do so, subjects were instructed to keep fixation on a target. Eye tracking was used for gaze control. Change of perceived motion direction was measured in a direction identification task. The point of subjective equality, that is, the angle at which a group of coherently moving dots was perceived as moving horizontal, was determined for both retinal locations. The shift of perceived motion direction was evaluated by comparing PSE before and after adaptation. A significant shift at both retinal locations in the direction of the skew distortion of the corresponding adaptation stimulus is demonstrated. Consequently, parallel adaptation to two opposing distortions in a retinotopic reference frame was confirmed by this study. (shrink)

When considering external assistive systems for people with motor impairments, gaze has been shown to be a powerful tool as it is anticipatory to motor actions and is promising for understanding intentions of an individual even before the action. Up until now, the vast majority of studies investigating the coordinated eye and hand movement in a grasping task focused on single objects manipulation without placing them in a meaningful scene. Very little is known about the impact of the scene context (...) on how we manipulate objects in an interactive task. In the present study, it was investigated how the scene context affects human object manipulation in a pick-and-place task in a realistic scenario implemented in VR. During the experiment, participants were instructed to find the target object in a room, pick it up, and transport it to a predefined final location. Thereafter, the impact of the scene context on different stages of the task was examined using head and hand movement, as well as eye tracking. As the main result, the scene context had a significant effect on the search and transport phases, but not on the reach phase of the task. The present work provides insights into the development of potential supporting intention predicting systems, revealing the dynamics of the pick-and-place task behavior once it is realized in a realistic context-rich scenario.

This article draws on the philosophical work on dialogic rationality offered by Charles Taylor as well as qualitative studies of dialogues between politically opposed college students to argue that these conversations succeed as tools of democracy precisely because they fail as interventions. That is, the democratic strength of such dialogue is the way in which it is unreliable as a means of producing particular outcomes. Students whose political views eventually shifted partly in response to dialogue understood this not as a (...) process of changing their commitments, but rather of finding a better expression for the commitments they already held. But the interviews show, too, just how rare it is for such shifts to occur at all, at least for these students in a period of political polarization and mutual distrust. The interviews suggest as well that the appeal to already shared ground is not the whole story of what prompts people to change their minds in these kinds of conversations. Rather the asking of direct but respectful questions was a crucial ingredient. Finally, dialogue did not independently cause the most profound changes in political views. Instead, it was the direction of students' lives that over time shifted their outlook. Their dialogue experience then gained meaning in retrospect, as the beginning of a process of self-questioning that was brought to fruition only later, as a first time that they had heard alternative possibilities for how value commitments can be expressed through politics.

William C. Hackett s English translation of Jean Wahl s "Existence humaine et transcendence" (1944) brings back to life an all-but-forgotten book that provocatively explores the philosophical concept of transcendence. Based on what Emmanuel Levinas called Wahl s famous lecture from 1937, "Existence humaine et transcendence" captured a watershed moment of European philosophy. Included in the book are Wahl's remarkable original lecture, the debate that ensued, with significant contributions by Gabriel Marcel and Nicolai Berdyaev, as well as (...) letters submitted on the occasion by Heidegger, Levinas, Jaspers, and other famous figures from that era. Concerned above all with the ineradicable felt value of human experience by which any philosophical thesis is measured, Wahl makes a daring clarification of the concept of transcendence and explores its repercussions through a masterly appeal to many (often surprising) places within the entire history of Western thought. Apart from its intrinsic philosophical significance as a discussion of the concepts of being, the absolute, and transcendence, Wahl's work is valuable insofar as it became a focal point for a great many other European intellectuals. Hackett has provided an annotated introduction to orient readers to this influential work of twentieth-century French philosophy and to one of its key figures. "Augmented by William C. Hackett's comprehensive introduction to Jean Wahl and his summary of Wahl's seminal "Human Existence and Transcendence," we now have Wahl's most important writings in English. The book presents the well-known ideas of transascendence and transdescendence and, in so doing, highlights the relevance of Wahl's 'philosophy of transcendence' today. Remarkable for its anticipations of later French thought, Wahl's work provides a key to much of what remains hidden in the tradition of twentieth-century French thought."

Das Böse: abstoßend und anziehend zugleich.

Dispositional essentialism is a non-Humean view about the essences of certain fundamental or natural properties that looms large in recent metaphysics , not least because it promises to explain neatly the natural modalities such as laws of nature, counterfactuals, causation and chance. In the current paper, however, several considerations are presented that indicate a serious tension between its essentialist core thesis and natural “metaphysical” interpretations of its central explanatory claims.

Parues pour la premiere fois en 1938, les Etudes kierkegaardiennes de Jean Wahl constitutent a tous egards une somme incontournable pour comprendre le sens de la philosophie de Kierkegaard et la place si originale qu'elle occupe dans l'histoire de la philosophie. L'auteur s'efforce d'y faire apparaitre le lien existant entre les evenements qui marquerent la vie de Kierkegaard et la formation de ses concepts fondamentaux. Par ce biais, l'auteur montre comment la theorie des trois stades de l'existence fait appel (...) a une dialectique qualitative, opposee a la dialectique hegelienne. L'auteur montre enfin que la theorie des trois stades de la croyance et de l'existence qui lui sont liees sont inseparables d'une lutte entreprise contre les pensees qui contribuerent a la genese de la pensee de Kierkegaard et qu'il s'agit a present pour lui de depasser: il n'y a pas de chemin qui conduit de la pensee, du cogito, a l'etre, au sum, car l'existence est l'etre hors de toute pensee.

Ecrire une lettre peut être tout à la fois approfondissement de sa propre réflexion, don à l'autre d'une partie de ses idées, et poursuite d'un lien d'amitié... Telle est bien l'impression qui se dégage à la lecture des lettres que Jean Wahl a écrites, essentiellement de 1907 à la fin des années 20 (il atteignait alors ses quarante ans), à Paul Tuffrau, un intellectuel comme lui, littéraire alors qu'il était philosophe, qu'il avait connu lors de ses études. Ces lettres (...) représentent un précieux témoignage des cheminements d'un esprit qui se construit. Jean Wahl y aborde de nombreux champs de la philosophie, allant de Bergson à Hegel, revenant à Platon, étudiant William James, tout en explorant des écrivains tels que Shelley ou Novalis, qu'il lit sous l'angle de l'écriture, et de la pensée... Elles sont aussi l'écho des mouvements politiques et sociaux, littéraires, picturaux ou musicaux de cette période si agitée, qui a vu l'irruption de la Première Guerre mondiale, et un entre-deux-guerres lourd de menaces...

Abstract:While the rise of a ‘dictatorship of relativism’ was a longstanding concern for Joseph Ratzinger/Pope Benedict XVI, some commentators have suggested that—for better or for worse—the challenge posed by relativism appears to be less of a priority for Pope Francis. Indeed, Francis's remark, ‘Who am I to judge?’ appears to have become as much the defining soundbite for his papacy as the ‘dictatorship of relativism’ was for Benedict's. Contrary to these perceptions, this article argues that a critique of relativism is (...) in fact a central aspect of Pope Francis's magisterium. Francis exhibits continuity with Benedict by amplifying his concerns about the danger of attempting to reconstruct reality according to human desire, but Francis also develops his predecessor's teaching by introducing the category of ‘practical relativism’. With this development, relativism cannot be dismissed as a theoretical problem that only plagues those who refuse to assent to the truth intellectually. The willingness to set aside the truth to which one assents when it proves inconvenient represents a more pernicious—precisely because more subtle—form of relativism that Francis argues must be rooted out, not by argument, but through self‐examination and the practice of solidarity.

Einleitend wird über die vielfältigen Vorteile wissenschaftlichen Arbeitens im Alter geschrieben. Die fünf Aufsätze des Buches widmen sich Randbereichen philosophischen Denkens. Auf dem Lande war vom 16. bis zum 19. Jahrhundert von Akademikern nur der Pfarrer gefragt, statt der akademisch gebildeten Mediziner nutzte man die aus dem Handwerk (z.B. Bader) herkommenden "Volksmediziner". Ebenso Astrologie und Alchemie. Die Dorfschullehrer hatten ebenfalls keine akademische Ausbildung. Über Philipp Melanchthon gibt es eine Vielzahl von Literatur. Sein Verhältnis zu den verschiedenen Richtungen der Häretiker, so (...) zu den Täufern, den Unitariern, zu Sebastian Franck und Caspar von Schwenckfeld ist bislang aber weniger behandelt. Auch der Chiliasmus des 16. und 17. Jahrhunderts ist gleich Utopie, Apokalyptik, Messianismus oder Eschatologie in Deutschland relativ selten philosophisches Arbeitsgebiet. Das gilt auch für Ehrenfried Walther von Tschirnhaus, Christian Weise und Johann Jakob von Hartig, "drei Glanzlichter der Oberlausitz". Bei Moses Mendelssohn wird vornehmlich seine Toleranzposition von 1782 dargelegt, dabei Toleranz und Intoleranz auch in Staat und Kirche bestimmt"--Back cover. (shrink)
