This collection of essays by Gregor Sebba (1905-1985) reflects the curiosity and insight of his mind. The range of topics is wide, including philosophy and the history of ideas, literature and art; yet there is a single underlying theme - human creativity and the search for truth - pursued along paths as diverse as Greek tragedy, Eric Voegelin's concept of order in history, and the poetry of Rainer Maria Rilke and T.S.Eliot.

Its author was a Carthusian monk. Offered here is a translation, with annotation and an important introduction, of the four books on natural philosophy, the predecessor of modern science.

In their practice, nurses make daily decisions that are ethically informed. An ethical decision is the result of a complex reasoning process based on knowledge and experience and driven by ethical values. Especially in acute elderly care and more specifically decisions concerning the use of physical restraint require a thoughtful deliberation of the different values at stake. Qualitative evidence concerning nurses’ decision-making in cases of physical restraint provided important insights in the complexity of decision-making as a trajectory. However a nuanced (...) and refined understanding of the reasoning process in terms of ethical values is still lacking. A qualitative interview design, inspired by the Grounded Theory approach, was carried out to explore nurses’ reasoning process in terms of ethical values. We interviewed 21 acute geriatric nurses from 12 hospitals in different regions in Flanders, Belgium in the period October 2009–April 2011. The Qualitative Analysis Guide of Leuven was used to analyse interview data. Nurses’ decision-making is characterized as an ethical deliberation process where different values are identified and where the process of balancing these values forms the essence of ethical deliberation. Ethical decision-making in cases of physical restraint implies that nurses have to choose which values receive priority in the process, which entails that not all values can be respected to the same degree. As a result, decision making can be experienced as difficult, even as a dilemma. Driven by the overwhelming goal of protecting physical integrity, nurses took into account the values of dignity and justice more implicitly and less dominantly. (shrink)

Gregor Betz explores the following questions: Where are the limits of economics, in particular the limits of economic foreknowledge? Are macroeconomic forecasts credible predictions or mere prophecies and what would this imply for the way economic policy decisions are taken? Is rational economic decision making possible without forecasting at all?

Wie ist es philosophisch zu erklären, dass Menschen frei und selbstbestimmt Entscheidungen treffen, die durch das klassische Begründungsmuster der Eigennützlichkeit und Selbsterhaltung unverständlich bleiben? Der Autor rekonstruiert und erweitert mit seiner neuartigen Konzeption - der autoeidetischen Struktur - Möglichkeitsbedingungen der praktischen Vernunft. Im Mittelpunkt steht dabei die eigene Existenz. Das Streben nach Selbsttreue bedingt das Wollen des Gesollten. Urteil und Praxis werden hierdurch nachvollziehbar zu Bedingungen gelingenden Lebens."--Publisher's website.

Brian Gregor draws together a hermeneutics of the self—through Heidegger, Gadamer, Ricoeur, and Taylor—and a theology of the cross—through Luther, Kierkegaard, Bonhoeffer, and Jüngel.

When does a human being begin to exist? Barry Smith and Berit Brogaard have argued that it is possible, through a combination of biological fact and philosophical analysis, to provide a definitive answer to this question. In their view, a human individual begins to exist at gastrulation, i. e. at about sixteen days after fertilization. In this paper we argue that even granting Smith and Brogaard's ontological commitments and biological assumptions, the existence of a human being can be shown to (...) begin much earlier, viz., with fertilization. Their interpretative claim that a zygote divides immediately into two substances and therefore ceases to exist is highly implausible by their own standards, and their factual claim that there is no communication between the blastomeres has to be abandoned in light of recent embryological research.

Wo Meinungen aufeinanderprallen, um Verständnis geworben und Überzeugungsarbeit geleistet wird, sind Begründungen nicht weit. Für jede Überzeugung gibt es immer ein, zwei Gründe, die mit Gegengründen konfrontiert und, im Gegenzug, mit weiteren Überlegungen verteidigt werden usw. usf. Schnell sind wir verwirrt und drohen, ohne uns der "Grammatikregeln" vernünftigen Argumentierens zu besinnen, nicht mehr durchzublicken. Die Theorie dialektischer Strukturen leistet einen Beitrag zur Grammatik vernünftigen Argumentierens. Sie stellt Begriffe und Verfahren bereit, um Fragen, die sich angesichts einer komplexen Argumentation stellen können, (...) zu beantworten: Wie beziehen sich die einzelnen Argumente der Debatte aufeinander? Welche Positionen vertreten die verschiedenen Proponenten, und wie lassen sich diese bewerten? Wie gut ist die zentrale These der Kontroverse alles in allem begründet? Ist die und die Argumentationshandlung angesichts des Debattenstandes tatsächlich zweckmäßig und rational? Liegt hier eine zirkuläre - und damit fehlerhafte - Argumentation vor? Die klassische Logik, die sogenannte informal logic und argumentationstheoretische Ansätze der Künstlichen Intelligenz bilden Anknüpfungspunkte der Theorie dialektischer Strukturen. Exemplarisch werden die entwickelten argumentationstheoretischen Methoden zur Analyse umfangreicher philosophischer Kontroversen eingesetzt. (shrink)

This paper develops a natural-language agent-based model of argumentation (ABMA). Its artificial deliberative agents (ADAs) are constructed with the help of so-called neural language models recently developed in AI and computational linguistics. ADAs are equipped with a minimalist belief system and may generate and submit novel contributions to a conversation. The natural-language ABMA allows us to simulate collective deliberation in English, i.e. with arguments, reasons, and claims themselves — rather than with their mathematical representations (as in symbolic models). This paper (...) uses the natural-language ABMA to test the robustness of symbolic reason-balancing models of argumentation (Mäs & Flache 2013; Singer et al. 2019): First of all, as long as ADAs remain passive, confirmation bias and homophily updating trigger polarization, which is consistent with results from symbolic models. However, once ADAs start to actively generate new contributions, the evolution of a conversation is dominated by properties of the agents as authors. This suggests that the creation of new arguments, reasons, and claims critically affects a conversation and is of pivotal importance for understanding the dynamics of collective deliberation. The paper closes by pointing out further fruitful applications of the model and challenges for future research. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:174 HISTORY OF PHILOSOPHY (960-1279) was in many aspects one of the most brilliant eras in Chinese history. One sees in this period the improvement of the bureaucratic system, the flourishing of a new poetic genre, the tz'u, a fresh approach to the study of Confucian cla~ics, the advancement of historiography and the rise of Neo-Confucianism. Ou-yang Hsiu (1907-1072) pioneered in all these magnificent political, cultural, and literary achievements. (...) Inevitably, he became a controversial figure to his contemporaries, and to later generations as well. There has not been a complete and balanced study, however, of this well-known and well-remembered man. Perhaps he was too broad and diverse a historical figure to be approached and studied easily. Professor Liu's book deserves our congratulations not merely for its well organized and scholarly presentation, but also for its successful approach to the subject from various angles. Ou-yang Hsiu was an official, a classicist, a political theorist, a historian, an essayist, and a poet. Accordingly this book gives separate chapters on Ou-yang Hsiu the classicist, the his= torian, the political theorist, the master of Sung literature, etc. With profound knowledge and sure control, the author organizes his materials so that the reader will not lose sight of the main points of the study. The best feature of this book (this reviewer feels) is that the author gives equal recognition to Ou-yang Hsiu the man and to the period in which he lived. Professor Liu ably and thoughtfully presents the historical characteristics of the Sung dynasty through Ou-yang Hsiu, and evaluates the merits and shortcomings, accomplishments and hmitations of Ouyang Hsiu against the peculiarity of his time. The subtitle of this book, An Eleventh=Century Neo=Con]ucianist, is most suitable. NeoConfucianism has always been studied abstractly as a philosophy, but Professor Liu's book shows us how this philosophy has been embodied in, substantialized, and practiced by "a key historical figure" who "gives us a finer perspective of his whole era."

(Paris: Gamier Fr~res, 1967. [Classiques Gamier.] Pp. 1148.12 plates. Fr 29.-) Opere scientifiehe di Ren$ Descartes. A cura di Gianni Micheli. Vol. I: La Biologia. (Torino: Unione Tipographico-Editrice Torinese, 1966. Pp. 520. 6 plates.-Classici della scienza, ed. Ludovico Geymonat, No. 6/I. L 6,000.) The second volume of the Edition Alqui~ confirms what was said here when Volume I appeared (JHP, II [1964], 260f.): this edition supersedes all currently available study editions. Volume II continues the rigorously chronological arrangement which singularly suits the philosophical writings of Descartes' "metaphysical period." Like no other edition, this one illuminates the often forgotten character of Descartes' philosophizing as an interaction between an ongoing dialogue (correspondence and replies to critics) and rigorously systematic thought. Imbedded in the stream of letters we find the Meditations not as a monolithic block, but as a sequence of three publications: the Latin text inserted at the time-point of its completion, April 1640; the French text with the first six Objections and Responses, August 1641; and at the end of the volume, the Seventh Objections and Responses and the letter to Diner. Only the Objections of Gassendi and Bourdin have been slightly cut. The volume concludes with the Recherche de la v~rit~ of unascertainable date (Aliqui~ thinks that it fits best into the 1641-42 context, without insisting on his conjecture). We thus have an edition that allows us to read the Meditations as Descartes' contemporaries---friends and adversaries --did. Once again the editor's notes are admirable, and there are brief but important critiques of the revised AT volume containing the Meditations, based on source studies by the editor, Henri Gouhier, and by Leslie J. Beck. Since the Edition Alqui$ covers only the philosophical works, it is a pleasure to report a new Italian collection and translation of Descartes' scientific works by Professor Gianni BOOK REVIEWS 175 Micheli of the Institute of History of Philosophy at the University of Milan.

In this article, I engage with three overlapping expressions of the increasingly postsecular cast of social and cultural theory. These currents — guided, respectively, by genealogical critique, neo-vitalist social philosophy and postcolonial anti-historicism — seek to problematize the frame of previous radical theorizing by exposing definite connections between the epistemological and political levels of secular understanding, and by assuming that the nature of those linkages counts heavily against secularism. As well as offering an interpretive overview of these contributions, I suggest (...) that they are traversed by a number of conceptual flaws and inconsistencies. The tensions, I argue, stem from the fact that in spite of appearing to be driven by a strong anti-secular thrust, these positionings remain thoroughly intra-secular in character. This needs to be more emphatically acknowledged if the ‘postsecular turn’ is to be productive. (shrink)

A distinction between different notions of “structure” and “function” is suggested for interpreting the overwhelming amount of data on microbiome structure and function. Sequence data, biochemical agents, interaction networks, taxonomic communities, and their dynamics can be linked to potential or actual biochemical activities, causal roles, and selected effects, respectively. This conceptual clarification has important methodological consequences for how to interpret existing data and approach open questions in contemporary microbiome research practice. In particular, the field will have to start thinking about (...) notions of function more directly. Also see the video abstract here https://youtu.be/j5pq5uGld1k. (shrink)

Examining developments in two of the central traditions of social and political theory - Marxism and pluralism, this work investigates whether the relation between them is one of progressive convergence.

Menschliches Bewusstein findet sich immer schon als verkörpertes vor. Diese Einsicht steht im Zentrum des kognitionswissenschaftlichen Paradigmas der embodied cognition: Der Geist ist „innig an einen Körper gebunden und innig in seine Welt eingebettet“. Der Geist ist kein in einem vermeintlichen Innenraum verborgenes und von der Welt weitgehend gelöstes neuronales Netzwerk, sondern als eine dynamische Weise des leiblichen In-der-Welt-Seins zu verstehen. Mit der Philosophie der Verkörperung gewinnt die Theologie einen Gesprächspartner, der ihr hilft, ihre eigene Körpervergessenheit zu überwinden und Anschluss (...) an die biblischen Anthropologien zu gewinnen. Denn diese verstehen die menschliche Existenz grundsätzlich als leiblich verfasst. Aktuelle Forschungen an der Schnittstelle von Neurobiologie und Philosophie einerseits und Exegese und Systematik andererseits lassen sich so in einen spannenden Diskurs bringen, an dessen Ende eine neue interdisziplinäre Anthropologie stehen könnte. Der vorliegende Band eröffnet diesen Diskurs mit Beiträgen aus Philosophie, Exegese und Systematischer Theologie. (shrink)

Gregor Paul, Philosoph an der Universität Karlsruhe, will zeigen, “dass ein Krieg gegen den Terrorismus unmöglich wäre, wenn man gültiger Argumentation folgte”. Die Frage ist, ob es einen „gerechten Krieg“ überhaupt gibt – eine alte Frage, auf die nicht nur in der abendländischen Philosophie unterschiedliche Antworten gegeben worden sind. Paul lässt hier die alte chinesische Philosophie zu Wort kommen. An den Beispielen der Kriege in Afghanistan und Irak wie dem sogenannten Krieg gegen den Terrorismus zeigt Paul, wie für deren (...) “Gerechtigkeit” nicht nur nicht offen argumentiert, sondern eine notwendige allseitige Diskussion verhindert wurde. Erst eine solche offene Diskussion würde das Gewicht der Argumente zeigen und Paul ist überzeugt, dass die Argumente für Kriege jeglicher Art vor dem Forum der Vernunft als zu leicht befunden würden.

The dynamics of neural populations capture the laws of the mindThis paper focuses on the level of neural networks. Examining the case of recurrent neural networks, the paper argues that the dynamics of neural populations form a privileged level of explanation in cognitive science. According to Schöner, this level is privileged, because it enables cognitive scientists to discover the laws governing organisms’ cognition and behaviour.

Published in 1785, Immanuel Kant's Groundwork of the Metaphysics of Morals ranks alongside Plato's Republic and Aristotle's Nicomachean Ethics as one of the most profound and influential works in moral philosophy ever written. In Kant's own words, its aim is to identify and corroborate the supreme principle of morality, the categorical imperative. He argues that human beings are ends in themselves, never to be used by anyone merely as a means, and that universal and unconditional obligations must be understood as (...) an expression of the human capacity for autonomy and self-governance. As such, they are laws of freedom. This volume contains Mary Gregor's acclaimed translation of the text into English, revised by Jens Timmermann, and an accessible, updated introduction by Christine Korsgaard. (shrink)

"The objective of this book is to review the complex of issues in Soren Kierkegaard's concept of existence. It is evident that for Kierkegaard existence is always composed of three elements: namely, the subject, freedom, and the ethical. In the process of clarifying the relation between these three elements in the different stages of existence, the course of the development the individual must go through in order to become the single individual is described. "The study falls into four parts. The (...) first section describes the levels in existence on which as person attempts by his own powers to actualize the ethical ideals; in this stage the center of gravity for a person's effort still lies within the bounds of immanence. The second section describes a person's ethical and religious growth as it develops in relation to a transcendent power, whose highest expression is Christ as the revelation of God. The third section discusses the issues in existence that Kierkegaard himself designated as the most difficult of all for human thought. The last section points to the highest existential position to which philosophy in the broader sense and Christianity respectively can take a person. Kierkegaard utilizes these positions as a standard for evaluating existence within immanence and for Christian existence. (shrink)

ALTHOUGH the content of Alexander Gottlieb Baumgarten's Aesthetica seems to be familiar in German philosophical circles, it is relatively unknown outside Germany. Most of us are aware that it was Baumgarten who coined the name "aesthetics" for the new philosophical discipline his Aesthetica was intended to establish; but as for the content of that work, our acquaintance is likely to be indirect, through two remarks of Kant. Explaining his own use of "Transcendental Aesthetic" in the Critique of Pure Reason, Kant (...) criticizes Baumgarten's "abortive attempt... to bring the critical treatment of the beautiful under rational principles and so to raise its rules to the rank of a science". In the Critique of Judgment, it is generally assumed to be Baumgarten Kant has in mind when, arguing that judgments of beauty are not cognitive or "logical" judgments, he criticizes the view that beauty is perfection known confusedly or indistinctly. Combining Kant's remark with Leibniz's view that beauty is--or, more precisely, flows from--perfection, we might conclude that Baumgarten simply lowered beauty from the level of distinct to that of confused concepts and tried to deduce its rules from the concept of perfection. If this was indeed Baumgarten's project, we might well ask to be excused from pursuing the subject further. (shrink)

If Kant's account of rights had continued the "early modern Natural Law tradition", basing rights on some notion of human flourishing, there would be no difficulty about including socio-economic rights for the needy in his theory. However, his division of moral philosophy into Rechtslehre and Tugendlehre limits Rechtspflichten to duties that a moral agent can be coerced to fulfill. If a state is to give the needy statutory rights, the justification for using coercion on its citizens cannot be that they (...) have a duty of virtue to assist the needy. In order to determine whether such a justification can be found, the one innate socio-economic right Kant admits, a child's right to be cared for and educated, is examined and found to be a right against its parents, not against the state. Kant does, however, hold that a state should establish institutions to provide for abandoned children and for the poor in general. His justification for a state's use of coercion with regard to such statutory rights is considered and a criterion is suggested for the possible consent of its non-virtuous citizens to proposed measures for assistance to the needy. It is suggested that if advocates of aid to the needy cannot justify their proposals by such a criterion they will have to provide a very different account of rights than Kant gives in his Rechtslehre , which is concerned with the moral permissibility of using coercion. Wenn Kants Lehre von den subjektiven Rechten nichts anderes wäre als eine Fortsetzung der "ihr vorangehenden modernen Naturrechtstradition" und die subjektiven Rechte infolgedessen auf das eine oder andere Konzept von menschlichem Wohlergehen gestützt hätte, dann wäre es nicht sonderlich schwierig, sozio-ökonomische Rechte für die Bedürftigen in diese Lehre einzubauen. Nun schränkt Kants Einteilung der Moralphilosophie in Rechtslehre und Tugendlehre den Begriff der Rechtspflicht allerdings auf diejenigen Pflichten ein, zu deren Erfüllung ein Mensch gezwungen werden kann. Deshalb kann, wenn ein Staat den Bedürftigen durch ein positives Gesetz irgendwelche Rechte auf Hilfe gewährt, die Rechtfertigung der Anwendung von staatlichem Zwang nicht darin gesucht werden, daß die dadurch in Anspruch genommenen Personen die Tugendpflicht haben, die Bedürftigen zu unterstützen. Um festzustellen, ob sich staatlicher Zwang in bezug auf solche Hilfspflichten überhaupt rechtfertigen läßt, erörtert der Beitrag das Recht des Kindes auf Fürsorge und Ausbildung als das eine und einzige angeborene sozio-ökonomische Recht, das Kant akzeptiert. Freilich ist das Recht des Kindes ein Recht gegen seine Eltern und nicht gegen den Staat. Gleichwohl nimmt Kant an, daß der Staat Einrichtungen schaffen sollte, die für verlassene Kinder und für die Armen im allgemeinen zu sorgen haben. Der Beitrag untersucht die Rechtfertigung, die Kant für die Anwendung von staatlichem Zwang zur Durchsetzung solcher positiv-gesetzlicher Rechte gibt, und arbeitet die Gründe dafür heraus, warum der nicht tugendhafte Staatsbürger in die vorgesehenen Hilfsmaßnahmen für die Bedürftigen einwilligen könnte. Wenn sich die Verfechter von Hilfsmaßnahmen für die Bedürftigen außerstande sehen, ihre Vorschläge auf Gründe dieser Art zu stützen, dann werden sie mit einem Konzept von subjektivem Recht aufwarten müssen, das sich von dem Konzept Kants von Recht und Rechtslehre , bei dem es allein um die moralische Erlaubtheit von Zwangsmaßnahmen geht, ganz erheblich unterscheidet.

Als ›Climate Engineering‹ bezeichnet man großtechnische Eingriffe in das Klimasystem, die darauf abzielen, den anthropogenen Klimawandel zu kompensieren.

This paper investigates in how far a theory of dialectical structures sheds new light on the old problem of giving a satisfying account of the fallacy of petitio principii, or begging the question. It defends that (i) circular argumentation on the one hand and petitio principii on the other hand are two distinct features of complex argumentation, and that (ii) it is impossible to make general statements about the defectiveness of an argumentation that exhibits these features. Such an argumentation, in (...) contrast, has to be evaluated on a case-by-case basis. “Petitio principii”, this paper thence suggests, is one name for, in fact, a multitude of different and quite complex dialectical situations which require specific analysis and evaluation.

In this article, we review the psychology of hero development and hero worship. We propose that heroes and hero narratives fulfill important cognitive and emotional needs, including the need for wisdom, meaning, hope, inspiration, and growth. We propose a framework called the heroic leadership dynamic to explain how need-based heroism shifts over time, from our initial attraction to heroes to later retention or repudiation of heroes. Central to the HLD is idea that hero narratives fulfill both epistemic and energizing functions. (...) Hero stories provide epistemic benefits by providing scripts for prosocial action, by revealing fundamental truths about human existence, by unpacking life paradoxes, and by cultivating emotional intelligence. To energize us, heroes promote moral elevation, heal psychic wounds, inspire psychological growth, and exude charisma. We discuss the implications of our framework for theory and research on heroism, leadership processes, and positive psychology. (shrink)

The highest goal of classic Confucianism was to contribute to the realization of a humane world. As means toward such a realization, it advocated rational methods, particularly logic, experience, and critically rational discourse. Thus, classic Confucianism reflected the view that rationality is more favorable to humanity than non-rationality. Today, classic Confucianism would belong to those schools which argue against the popular inclination toward mysticism and sectarianism, - an inclination widespread in the «West» and often defended by hinting at alleged evidence (...) from «Eastern» cultures. Above all else, it is with such points that Confucianism proves its relevance. In advancing and defending this thesis, Aspects of Confucianism suggests, contrary to a widespread opinion, that we can learn a great deal from such obvious cultural commonalities as the basic features of a universal rationality, that obvious commonalities are by no means uninteresting, and that their description and appreciation is not necessarily an expression of a cultural bias.

This article explores the interface between cultural studies and soci ology, as expressed through four scenarios which construe the 'debate' in particular ways. Two of these - 'cultural studies succession' and 'postmodernist conjuncturalist cultural studies' - unapologetically seek to dismiss sociology in favour of cultural studies, whilst a third - 'socio logical revenge' - appears to turn the tables entirely. A fourth and more productive scenario dwells synthetically on the 'cultural turn' across the whole 'field' of the social and human (...) sciences. All four postures dis cussed are found to share two problematical features. The first of these is that although rhetoric/discourse is crucial in the construction of iden tities, including disciplinary identities, over-rhetorical manifestos readily generate critical doubts about their consistency and appropri ateness. Second, the focus in the four scenarios is chiefly on disciplinary homes, fields, or turns rather than, as it perhaps should be, on substan tive theses or ideological positions within these.

With the evidence for anthropogenic climate change piling up, suggesting that climate impacts of GHG emissions might have been underestimated in the past (Allison et al. 2009; WBGU 2009), and mitigation policies apparently lagging behind what many scientists consider as necessary reductions in order to prevent dangerous climate change, the debate about intentional climate change, or “climate engineering”, as we shall say in the following, has gained momentum in the past years. While efforts to technically modify earth’s climate had been (...) the focus of sporadic discussions at least since the White House’s Report “Restoring the Quality of Our Environment” (cf. Keith 2000), Paul Crutzen’s cautious plea for research into the feasibility and side-effects of stratospheric sulphur injections (Crutzen 2006) has incited an inter-disciplinary controversy (with a preliminary culmination in the Royal Society’s assessment (Royal Society 2009)), while increasing public awareness and debate about climate engineering, as well. The controversy, though, does not focus on the question whether climate engineering should be carried out today (which is largely reckoned to be a bad idea, unnecessary, or premature) or at some point in the future (which is considered a decision we don’t have to take now), but on whether to engage in large-scale research into the alternative technological options for carrying out intentional climate change. It is this paper’s purpose to make that controversy more transparent. In order to do so, we analyse what seems to be the major argument in favour of research into climate engineering: the lesser evil-, or, as Stephen Gardiner has called it, the arm the future-argument — in short: the AF-argument (Gardiner 2010). Such an argumentative analysis makes explicit the normative and descriptive assumptions which underlie the reasoning, without ascertaining or denying them, and thus enables one to assess the overall strength of the argument as well as to determine which objections do, and which don’t undermine it.
