Die Abhandlung, ein Beitrag zur Geschichte der wissenschaftlichen Methoden, untersucht Johann Gottfried Herders Verwendung der Analogie als Instrument für die Entdeckung neuer Gebiete der Erkenntnis in den Bereichen seiner Naturphilosophie, der Geschichtsphilosophie und Literaturkritik. Abschließend wird Herders Verhältnis zum überlieferten Gedanken einer ars inveniendi bestimmt.

We show that given a simple Polygon P it is NP-hard to determine the smallest α ∈ [0, π] such that P can be illuminated by α-vertexlights, if we place exactly one α-vertexlight in each vertex of P.

First we give an overview about variants of visibility and related problems. Then we prove that some guarding and covering problems are NP-hard for ortho-polygons with holes, using a so-called vertex cover technique.

For each vertex of a simple polygon P an integer valued weight is given. We consider the path p1, p2, ..., pk in P which is created according to the following strategy: p1 is a designated start vertex s and pi+1 is obtained by choosing the vertex with smallest weight among all vertices visible from pi and different from p1, p2, ..., pi. If there is no such vertex the path is finished. This path is called geometric lexicographic dead end (...) path. We shall prove the problem of determining whether a distinguished vertex t of P is on the geometric lexicographic dead end path or not to be P-complete. (shrink)

We consider the problem of quadrilaterizing an orthogonal polygon P, that is to decompose P into nonoverlapping convex quadrangles without adding new vertices. In this paper we present a CREW-algorithm for this problem which runs in O time using Θ processors if the rectangle decomposition of P is given, and Θ processors if not. Furthermore we will show that the latter result is optimal if the polygon is allowed to contain holes.

D. T. Lee and A. K. Lin [2] proved that VERTEX-GUARDING and POINT-GUARDING are NP-hard for simple polygons. We prove that those problems are NP-hard for ortho-polygons, too.

Summary A large survey of German and Israeli younger and older adolescents was conducted to reveal their opinions and attitudes towards violence and aggression, their personal engagement in aggressive and violent behaviors in and outside the school environment, their attitudes toward physical activity, their engagement in physical activity, and the linkage between physical activity engagement and conductance of violence and aggression. The findings point out that there are more similarities than differences between German and Israeli adolescents concerning violence and aggression (...) in and outside schools. No linkage between physical activity involvement and the extent of violent and/or aggressive acts is found. The findings pertaining adolescents’ opinions and attitudes toward aggression and violence and their behaviors in and outside school are encouraging. (shrink)

Die Prinzipienbegrundungsfrage bzw. die einen Verbindlichkeitserweis erfordernde Frage "Was gilt?" verweist auf unsere grundlegende Mitverantwortung fur die im High-tech-Zeitalter bedrohte Menschheitszukunft. Um jene - zugleich hochpolitische - Prinzipienfrage geht es in diesem Diskurs- und Verantwortungsbuch: zunachst in Dietrich Bohlers einfuhrendem Essay, sodann in den acht Diskursen zwischen Jon Hellesnes, Gunnar Skirbekk, Hans Lenk, Alberto Damiani, Sebastian Hopfl, Vittorio Hosle, Thomas Rusche und Dietrich Bohler, der auf diese antwortet. Drei kritisch wurdigende Essays zu Hans Jonas' und Karl-Otto (...) Apels Verantwortungsdenken pointieren schliesslich die Aktualitat der Zukunftsethik. (shrink)

Advancements in biological ageing research have shown that age-related diseases may be fought more effectively in the future by directly intervening into the ageing process. This prospect is associated with hopes for solving problems of demographic change. It also addresses raising awareness for complex ethical, legal and social issues that have hardly been a topic of discussion to date. Therefore, as the objective of our project, an interdisciplinary discourse module entitled “Ethics of Biogerontology” was developed to initiate a social debate (...) on the ethical, legal, and societal implications of biogerontology. The discourse module focuses on competences and argumentation skills and was developed with experts from relevant disciplines, e.g. biogerontology, social gerontology, philosophy, geriatrics, and medical ethics. Concepts of age and ageing are tightly interlinked with biogerontology and are as such relevant as teaching contents of the discourse module. The course module was tested in eight discourse teaching projects in research, medicine, and education in various partner institutions and evaluated based on an ethical competence model. This article describes the conception, including the learning objectives, of such a teaching course and the associated teaching contents. It also gives a justification for their selection. Finally, we summarize the results of the evaluation. (shrink)

Nach drei Semestern war ich 1951 von München nach Köln umgezogen, weil ich mit Wirtschaftswissenschaft Ernst machen wollte. Im wirtschaftswissenschaftlichen Seminar traf ich zum ersten Mal auf Hans Albert. Obwohl er ein halbes Jahrzehnt älter war als ich, arbeitete er als studentischer Amanuensis in der ökonomischen Bibliothek.

Transcendental Pragmatics and Discourse Ethics. Elements and Perspectives of Apel's Discourse-Philosophy. The author follows Apel's intellectual biography and shows the conception of a critique of meaning qua ‘reflection upon the discourse within the discourse’ to be the centre of Apel's language-pragmatic ‘Transformation of Philosophy’. Beginning with an explication of the situation of a speaker/thinker, especially of the situation of a philosophising speaker/thinker, Apel reconstructs a two fold apriori of communication: Every thought is situated within the context of a particular, historically (...) evolved, community of language and interaction. At the same time, however, the validity-claims of thoughts transcend the context of their origin towards an unlimited community of argumentation. On the basis of the first apriori Apel criticises the methodical solipsism as well as the objectivism of modern philosophy and theory of science. Drawing upon the second apriori he develops a universalist critique of meaning of relativism and contextualism. In the sixties and seventies Apel worked out a differentiated theory of the – more or less – communicatively cognizing humanities and set it apart from the theory of the causal-explanatory natural sciences, thus challenging the objectivism of a Theory of Unified Science. Building upon this work Transcendental Pragmatics, as developed by Apel and others, sets philosophy primarily two tasks: firstly, a internal reconstruction of argumentative discourse as the situation of speech and thought which seeks to elucidate the conditions of the meaningfulness, i. e. the presuppositions, of discourse. These presuppositions comprise, thus Apel with Habermas, the four validity-claims to intelligibility, sincerety/credibility, truth and normative rightness/legitimacy. Their moral content consists, thus Apel, not only in the recognition of the equality of all beings capable of discursive reasoning but also in their recognition of a co-responsibility for the realizability of discourses and of responsibility. The author argues that the existence of a co-responsibility of this kind is indisputable because the discursive claims to validity are intertwined with a set of ‘primordial promises of dialogue’. Only with the elucidation and explication of these promises can the reconstruction of the internal conditions of discourse be completed.The second task of a pragmatics of argumentation isthe strict resp. actual reflection of the thinker upon the presuppositions of the discourse in which he currently engages. This reflection has a Socratic character and can only be done in the form of discussion and debate with critics of the reconstruction. In this context, the author proposes a method of Socratic reflection upon the presuppositions of dialogue which suspends the usual, theoretically oriented, attitude of the scientist and the philosopher in favour of an actual reflective attitude. Within a dialogue with a sceptic who doubts one of the results of the internal reconstruction of dialogical presuppositions, say X, it is tested whether his doubt as to the unrestricted validity of X can be understood as a sincere contribution to the current dialogue or whether this particular sceptical thesis does not make sense, because it is incompatible with the role of a sincere participant of argumentation which, after all, the sceptic cannot refuse to claim for himself.Finally the author explains Apel's characterization of the tension between “Discourse and Responsibility”. In the course of discussions with Max Weber, Lawrence Kohlberg, Hans Jonas et al., Apel formulates and justifies an ethics of responsibility and gives an affirmative answer to the crucial question of whether the fulfilment of the moral obligations connected with the recognition of co-responsibility can be demanded within the non-dialogical circumstances of social reality. Apel's answer employs the idea of counter-strategies which are morally legitimate in virtue of their being worthy of argumentative consensus. (shrink)

This is an edited version of an address by Hans-Georg Gadamer, presented at the Dietrich Bonhoeffer Gymnasium, Eppelheim, on 19 May 1999. The text has been edited and translated by John Cleary and Pádraig Hogan.

„On 23rd February 2022, when the editors had worked out topical issues of dispute relating to politics, ethics, technology and religion for a Hans Jonas Centre conference on responsibility for the future and discourse ethics, it was suddenly foreseeable that Russia would invade the core area of Ukraine the next night. We immediately informed our Ukrainian colleagues that we would allow them asylum, if desired, and invite them to the conference in Bad Kissingen as keynote speakers. In no time (...) at all, the new programme for the confer-ence was ready: After commemorating Hans Jonas' honorary doctorate in Berlin under the motto ‘Fatalism would be a mortal sin’ exactly 30 years ago, we now focus on ‘Discourse despite war’. After that, we discuss digitalisation as well as theology, philosophy and commitment".

El texto aristotélico Metafísica IV, 2, y sus interpretaciones por parte de los filósofos musulmanes, Avicena y Averroes, constituyen el marco teórico en el que se han elaborado las doctrinas acerca de los trascendentales, de varios autores latinos de la segunda mitad del siglo XIII de la Universidad de París, que se han posicionado en torno a la cuestión de la ‘distinción real’ entre el esse y la essentia. Según esto, nuestro trabajo busca trazar la dependencia de la doctrina general (...) de los trascendentales de Dietrich, respecto de las tesis establecidas por Aristóteles en dicho texto, y en particular, respecto de la lectura averroísta – crítica de la de Avicena –, que “ha hecho escuela” en el medio parisino, especialmente entre los maestros y estudiantes de la Facultad de Artes, pero incluso también primero en Tomás de Aquino. Así, a la luz de este entramado de lecturas e interpretaciones, buscaremos delimitar los rasgos centrales de la concepción teodoriciana de los communia, señalando las posibles discrepancias o coincidencias respecto de las doctrinas de estos autores precedentes.

The plan for this volume emerged during the international Leipzig conference commemorating the centenary of the death of Gustav Fechner.

Public and intellectual debates have long struggled with the concept of values and the difficulties of defining them. With _The Genesis of Values,_ renowned theorist Hans Joas explores the nature of these difficulties in relation to some of the leading figures of twentieth-century philosophy and social theory: Friedrich Nietzsche, William James, Max Scheler, John Dewey, Georg Simmel, Charles Taylor, and Jürgen Habermas. Joas traces how these thinkers came to terms with the idea of values, and then extends beyond them (...) with his own comprehensive theory. Values, Joas suggests, arise in experiences in self-formation and self-transcendence. Only by appreciating the creative nature of human action can we understand how our values arise. (shrink)

Nasr (Islamic studies, George Washington U.), in a series of ten lectures, argues that, unlike in the West, where scientific thought has been secularized, in the East, knowledge and religious experience have remained unified. Drawing from Buddhist, Hindu, Judaic, Christian, and Islamic traditions, he finds in each the idea of perennial wisdom as a philosophical basis for such unity. Paperback edition ($10.95) not seen. A reprint of the 1987 original with a new (short) preface. The paper edition (06459-4) is available (...) for $13.50. Annotation copyrighted by Book News, Inc., Portland, OR. (shrink)

Wittgenstein has often been ascribed a ‘use-theory of meaning’. However, he explicitly renounced theory construction. Furthermore, his slogan ‘Don’t ask for the meaning, ask for the use!’ invites circumventing the question ‘What is meaning?’ altogether. This chapter argues that, Wittgenstein’s ambivalence notwithstanding, there is no merit in avoiding the title question (‘What is meaning?’). Moreover, it is argued that, while Wittgenstein’s reflections are incompatible with a formal theory of meaning, they do lay the foundations of a viable account of the (...) concept of linguistic meaning, namely by elucidating its connections with other concepts like those of rule, explanation, and understanding. The chapter makes a case for a use-theory thus understood. (shrink)

Hans Rudi Fischer eröffnet vom Standpunkt einer philosophischen Analyse her einen neuen Zugang zu bestimmten Formen der Geisteskrankheit und damit zu ihrer psychotherapeutischen Analyse und Behandlung. Die Studie ist daher im Zwischenbereich zwischen Philosophie, Sprachtheorie und Psychologie bzw. Psychotherapie angesiedelt und somit für alle drei Bereiche von Interesse. Ihre Zielrichtung ist deshalb eine doppelte: Zum einen sollen Wittgensteins verstreute Bemerkungen zur Psychologie, zum Wahnsinn und zur Psychoanalyse in einer systematischen Interpretation ihres (bisher, wenn diese Bemerkungen überhaupt beachtet wurden, meist (...) unterstellten) kursorischen Charakters entkleidet und in einen konsistenten Zusammenhang mit seinem philosophischen Konzept von Sprachspiel, Grammatik und Lebensform gebracht werden. Zum anderen soll von dieser philosophisch gewonnenen Position her eine (weiterführende) Kritik an einigen Positionen der Psychoanalyse sowie an kommunikationstheoretischen Ansätzen in der Psychopathologie (Bateson und, auf ihn folgend, Watzlawick) geübt werden. Ergebnis ist eine philosophische Erklärung von Schizophrenie als Verschiebung der Grammatik (in Wittgensteins Gebrauch dieses Terminus) aufgrund devianter Lebensformen im sozialen Nukleus der Familie.
