In this paper, I'll present a general way of "reading off" introduction/elimination rules from elimination/introduction rules, and define notions of harmony and stability on the basis of it.

Many prominent writers on the philosophy of logic, including Michael Dummett, Dag Prawitz, Neil Tennant, have held that the introduction and elimination rules of a logical connective must be ‘in harmony ’ if the connective is to possess a sense. This Harmony Thesis has been used to justify the choice of logic: in particular, supposed violations of it by the classical rules for negation have been the basis for arguments for switching from classical to intuitionistic logic. The Thesis has also (...) had an influence on the philosophy of language: some prominent writers in that area, notably Dummett and Robert Brandom, have taken it to be a special case of a more general requirement that the grounds for asserting a statement must cohere with its consequences. This essay considers various ways of making the Harmony Thesis precise and scrutinizes the most influential arguments for it. The verdict is negative: all the extant arguments for the Thesis are weak, and no version of it is remotely plausible. (shrink)

The article outlines the Multiple-Field-Approach ("Mehr-Felder-Ansatz") in Gestalt Theoretical Psychotherapy and in psychotherapy in general. This Gestalt theory based approach deals 1) with the conditions under which a secondary phenomenal field (containing a secondary phenomenal ego and a secondary phenomenal environment) segregates within the primary phenomenal field, 2) with the dynamic field interaction between primary and secondary field and their role in psychotherapy, 3) with psychotherapeutic techniques favouring the segregation and favouring the dissolution of a secondary field . Some of (...) these phenomena have been discussed as mind-wandering, daydreaming, or - in a pathological context - as dissociation. But it seems that the Gestalt psychological approach presented in this paper has to offer a more promising framework for these phenomena and their dynamics. (shrink)

Dieser Beitrag erörtert die „übersinnlichen Erkenntnisse“ von Rudolf Steiner zum Thema der Beziehungen von Jesus zu den Essenern. Steiner beschäftigte sich in seinem Vortragszyklus „Das fünfte Evangelium“ mit dieser Frage und präsentierte Erkenntnisse seiner Forschungen aus der Akasha-Chronik. Um die Unabhängigkeit der Akasha-Forschungen von Steiner herauszufiltern, stellt der Autor die Forschungen der Theosophin Blavatsky den Erkenntnissen von Steiner gegenüber. Die Gegenüberstellung verfolgt das Ziel, die Grenzen und Möglichkeiten der Akasha-Forschungen Steiners zu erkunden. Die Arbeit zeigt, dass das fünfte Evangelium von (...) Steiner einige Grundaussagen über die Beziehung von Jesus zu den Essenern enthält, die man bereits bei Blavatsky in „Isis entschleiert“ findet. Dass Steiner die Forschungen ganz unabhängig von bereits vorhandenen Ergebnissen (von Blavatsky) betrieben hat, ist daher unwahrscheinlich. Steiner berichtet über persönliche Begegnungen von Jesus mit den Essenern, die man nirgendwo sonst in dieser Detailliertheit in der Literatur finden kann, und daher hat er einen zusätzlichen Beitrag zur esoterischen Forschung geliefert, der nicht übersehen werden sollte. Eine These, die sich aus dieser Arbeit ergibt, ist, dass Steiner methodisch sowohl den theosophischen Mediumismus als auch die meditative Schau der Akasha-Chronik, die er als exakter empfand, in seine Forschungen einfließen ließ.

The paper presents basic Gestalt psychological concepts of ego and self. They differ from other concepts in the way that they do not comprehend ego and self as fixed entities or as central controlling instances of the psyche, but as one specific organized unit in a psychological field in dynamic interrelation with the other organized units—the environment units—of this field. On this theme, well-known representatives of Gestalt theory have presented some general and special theories since the early days of this (...) approach that could partly be substantiated experimentally. They illuminate the relationship between ego and world in everyday life as well as in the case of mental disorders. Not only the spatial extension of the phenomenal ego is subject to situational changes, but also its place in the world, its functional fitting in this world, its internal differentiation, its permeability to the environment, and much more. The German Gestalt psychologist Wolfgang Metzger emphasizes the significant functional role that this dynamic plasticity of the phenomenal world and its continuously changing segregation of ego and environment have for human life by designating the phenomenal world as a “Central Steering Mechanism.” In this article, ego and self as part of this field in their interrelation with the total psychological field will be illuminated from the perspective of the thinking of the Gestalt psychologists Max Wertheimer, Kurt Koffka, Wolfgang Köhler, Kurt Lewin, Wolfgang Metzger, Mary Henle, Edwin Rausch, and Giuseppe Galli.

Summary Giancarlo Trombini presents the continuation of his research on the question of which criteria can be used to assess the progress of therapy in an objectively verifiable way and to make the decision on the completion of therapy. In the first phase of his research, the phenomenological criterion of a qualitative change in the patient’s relations toward the positive and higher complexity was proposed for this purpose. In terms of the working method in analytic therapy, this meant concretely: attention (...) should be paid to what development is shown in the comparison of the relationships that occur in the dream narrative and in the subsequent associations. This criterion was therefore given the name manifest dream/association comparison (MDAC)—comparison between the manifest dream and the subsequent associations. The idea can easily be transferred to those therapy methods, which do not primarily work with reports of dream memories and subsequent associations—also, in other ways of working, it is possible to pay attention, in the way suggested by Trombini, to the qualitative development of the relationships which are thematized by the clients in the course of an hour. To this first criterion, another phenomenological criterion is now added in the present article: that of the “concluding therapeutic turn” (CTT). If the patient’s development reaches this turn in the course of the therapy in one session, this indicates, according to Trombini, that the therapy can soon be concluded. The fulfillment of this criterion can be recognized by the fact that in the sequence of dream narration and subsequent associations in a session, a relational dynamic toward the positive and higher complexity becomes recognizable and that is, at the same time, connected with a reconciliation of the three temporal reference systems (past, present, and future). The achievement of this CTT indicates that the patient is aware of the changes made in therapy and makes it evident to the therapist that the therapy is nearing completion. (shrink)

La théorie de l’organisme social était une approche foncièrement et largement répandue au début du 20ème siècle, qui était acceptée par de nombreuses orientations théoriques dans la sociologie et l’économie. L’approche de Rudolf Steiner s’y rapportant est bien connue. La théorie de Gerhard Stolzmann ne l’est pas autant. Ce dernier était un représentant de ce qu’on appelle le « mouvement des droits sociaux de l’économie politique » et au plan philosophique, il défendait le néo-kantisme (école de Marburg, de l’Allemagne (...) du sud-ouest). Stolzmann a connu et cité les écrits de Steiner sur l’organisme social, comme on peut le prouver. Dans cet essai, on va mettre au jour les communautés et tendances dans le concept de l’organisme social chez Stolzmann et Steiner. Tous deux ont mis en exergue l’importance du spirituel et en conséquence de la sphère du droit, pour la société et l’économie dans leur théorie. Mais Steiner eut essentiellement une amorce plus pratique. Son concept d’organisme social est plus une proposition de réforme pour l’économie et la société, alors que Stolzmann fait ressortir la signification théorique générale toujours valable de sa théorie.

Sebastian Franck commented and translated parts of Agrippa´s De Vanitate Scientiarum, confirming that Franck knew at least some of this philosopher’s work. However, there is no detailed research on the influence Agrippa had on Franck—a gap this paper tries to fill. In a paper of Keefer, the author advocates that Franck was much influenced by Agrippa. The major claim of this paper is that Agrippa’s influence on Franck should not be overestimated, primarily because Franck deliberately did not cite from the (...) Occulta philosophia. Only De Vanitate Scientiarum and one paragraph of Oratio habita papiae are shown to have had a direct influence on Franck. The influence on Franck`s philosophy has to be analyzed very carefully to avoid such fallacies. In a comparison of the metaphysical belief systems of both Franck and Agrippa, important parallels concerning the soul and Christology can be found. Notably, Agrippa and Franck were both believers in the Platonic doctrine of the tripartite soul. However, Franck did not cite this concept from Agrippa. A difference between Agrippa and Franck was that Agrippa had a cosmological perspective that was strongly influenced by Neoplatonism and Hermeticism. In contrast, the Neoplatonic concept of the world soul did not make sense in Franck’s philosophical system of beliefs because Franck denies the idea that the world is conducted by rationality. His pessimistic view of the world and the human being did not blend with this idea of the world soul. These differences demonstrate that Franck did not agree with many concepts found in the Occulta philosophia. The Corpus Hermeticum was also not as important for Franck as it was for Agrippa. Franck focused primarily on the Pimander and to a certain extent on the thirteenth book (rebirth), whereas for Agrippa many parts were relevant. Research on the influence of the Hermetic books on Franck just began in the 21st century and this paper further contributes to a better understanding of how the Hermetic books affected Franck. Franck used Agrippa to convey his understanding of the Corpus Hermeticum to his readers. However, it remains an open question why Franck integrated only a small part of the Corpus Hermeticum and the writings of Agrippa into his philosophy. (shrink)

Pakṣilasvāmin's introduction to his Nyāyabhāṣyam is perhaps one of the most interesting texts of the older Nyāya indispensable to the understanding of the system. This is not because the ideas expressed therein were not to be surpassed at a later period, but because in it the development of the school appears fixed, as it were, in a "transitory moment" (transitorisches Moment), and we see there for the first time that line of thought, which historically took form in the Nyāya philosophy, (...) becoming aware of itself in a clear, though archaic, manner. Furthermore, if we bear in mind to what extent such an interpretation of a school (given by itself) determines its development, the importance of Pakṣilasvāmin's text for the history of Nyāya cannot be over-estimated.

Die Theorie des sozialen Organismus war zur Zeit des Beginns des 20. Jahrhunderts ein durchaus weit verbreiteter Ansatz der von vielen verschiedenen theoretischen Richtungen in der Soziologie und Ökonomie aufgenommen wurde. Bekannt ist der diesbezügliche Ansatz von Rudolf Steiner. Eher nicht so bekannt ist die Theorie von Rudolf Stolzmann. Letzterer war ein Vertreter der sogenannten sozialrechtlichen Richtung der Nationalökonomie und philosophisch war er ein Vertreter des Neukantianismus (Marburger Schule, Südwestdeutsche Schule). Stolzmann hat Steiners Schriften zum sozialen Organismus nachweislich gekannt und (...) auch zitiert. In diesem Aufsatz sollen Gemeinsamkeiten und Trennendes im Konzept des sozialen Organismus bei Stolzmann und Steiner gefunden werden. Stolzmann und Steiner haben die Bedeutung des Geistigen und in weiterer Folge des Rechtlichen für die Gesellschaft und Wirtschaft in ihrer Theorie hervorgehoben. Steiner hatte aber den wesentlich praktischeren Ansatz. Sein Konzept des sozialen Organismus ist mehr ein Reformvorschlag für Ökonomie und Gesellschaft, während Stolzmann die theoretische und immer gültige Bedeutung seiner Theorie hervorhebt. (shrink)

This addendum presents results that confound some commonly made claims about the sorts of environments in which the performance of TTB exceeds that of Franklin's rule, and vice versa.

Research on Sebastian Franck (1499 – 1543) has so far mainly focused on the topics “Sebastian Franck as a historian” or “Sebastian Franck as a critic of theology,” while Gnosticism in the philosophy of the radical reformer has received less attention. Since the beginning of the new millennium, the interest in a certain movement of Gnosticism, namely Hermeticism, has increased however. This paper examines the question of the parallels in content between Gnostic representatives such as the Carpocratians, the Ebionites, and (...) Sebastian Franck. Irenaeus of Lyon is used as a source for the Carpocratians and the Ebionites. Substantial similarities can be found in the fragmentary reports of Irenaeus on the Carpocratians and Ebionites and the teachings of Franck. The parallels between the Carpocratians and Franck can be identified in the concept of the Divine, the tripartite nature of the soul, and the doctrine of salvation. Unlike orthodox Christianity, both Franck and the Carpocratians believed in the self-salvation of people from their sins. Through the discovery of their spirit, all people can access the abilities that Yeshua had in his incarnation. The rejection of both the doctrine of original sin and the doctrine of grace is what Franck has in common with the Ebionites. However, the doctrine of grace would not make any sense for the Carpocratians either, as, according to their conviction, the soul is redeemed by the enlightenment of the spirit. (shrink)

Summary The article substantiates the possibility and meaningfulness of a coherent theoretical system for psychotherapy, as it is strived for in Gestalt Theoretical Psychotherapy and presented in several articles in this issue of the journal "Gestalt Theory". The necessity of consistency in the theoretical assumptions and concepts of a psychotherapy method is not derived from scientific considerations alone, but already arises from the elementary role of consistency in human life. This also results in the requirements for the consistency of theoretical (...) foundations of psychotherapy. It is not fulfilled in a mere internal, logical consistency of its models, but only in the actual fitting together with the critical-phenomenal and naive-phenomenal worlds of the therapists and their clients in the reality test of life.

Die Sebastian Franck-Forschung hat sich bisher recht ausführlich mit den Themen "Sebastian Franck als Historiker" oder "Sebastian Franck als Kritiker der Theologie" beschäftigt. Weniger Aufmerksamkeit bekam bisher der Gnostizismus im Denken des radikalen Reformers. Seit der Jahrtausendwende ist allerdings ein stärkeres Interesse an einer bestimmten Strömung des Gnostizismus zu erkennen, nämlich der Hermetik. Es gab einige Arbeiten, die den Einfluss von Hermes Trismegistos bzw. der hermetischen Schriften auf Franck aufzeigen konnten. Dieser Aufsatz geht der Frage des Einflusses des christlichen Gnostizismus (...) auf die Metaphysik von Franck nach. Die Ergebnisse zeigen, dass speziell Basilides und Valentinus einen starken Einfluss auf Franck hatten, der bisher nicht gesehen wurde. Eine große Bedeutung kommt dabei der gnostischen Soteriologie zu. Genauso wie Basilides und Valentinus nimmt Franck die platonische Dreiteilung der Seele in Geist, Seele und Körper an. Der Geist ist göttlich und ist weder entstanden noch kann er vergehen. Diesen Geist oder Christus findet man im Inneren von allen Kreaturen. Durch die Erkenntnis des Geistes oder Christus im Menschen, (=Gnosis) kann sich der Mensch von der Welt befreien. Ebenfalls christlich-gnostisch inspiriert ist der Gottesbegriff und die Lehre von Christus. Franck´s Christologie ist stark von der Nous-Christologie von Basilides beeinflußt, wobei er nicht exakt dem gleichen Doketismus folgt wie Basilides. Dass die Welt vom Demiurgen und nicht von Gott erschaffen wurde, wie Valentinus glaubt, sagt Franck nicht explizit. Franck glaubt aber der Teufel (Demiurg oder böser Engel) habe den Tod und damit die Seele erschaffen, während der unsterbliche Geist des Menschen nicht erschaffen wurde. (shrink)

Diese Arbeit behandelt die Frage, ob die Christengemeinschaft aus dogmatischer Perspektive Teil der Ökumene sein könnte. Es wurden dazu mehrere Hypothese überprüft und die Ergebnisse zeigen, dass die Christengemeinschaft inhaltlich zu weit von der Dogmatik der Ökumene abweicht. Eine Hypothese ist, dass die Christengemeinschaft zum gnostischen Strang innerhalb des Christentums gezählt werden kann. Die Hypothese wurde bejaht. Die größten Differenzen finden sich in der Christologie und beim Thema Reinkarnation. Die Christengemeinschaft ist eng an die Philosophie Rudolf Steiners orientiert und 90 (...) Prozent der Gläubigen glauben an die Reinkarnation und an die gnostische Inkarnationschristologie. (shrink)

There is a widespread belief in the academic world—above all in the United States and in the scientific communities around the world accepting U.S. mainstream science as their standard —that »schools« have lost their grounds and their legitimacy in psychology and other sciences.»Schools of thought« are seen as hampering freedom of thought and research, progress in science would have a better chance when free of such affiliations, and »objectivity« in science is seen to be best granted by some sort of (...) disinterested eclecticism.If you agree with such a premise, it is clear that it would not make much sense to run an international scientific society like the GTA, which explicitly feels committed to such a »school«. I am not the first one to object to such a view, more meritorious people have done so before me. (shrink)

Sebastian Franck hat Teile von Agrippas De Vanitate Scientiarum übersetzt und kommentiert. Von daher ist der Einfluss der Philosophie von Agrippa auf Franck bekannt. Es gab allerdings bisher keine ausführlichen Untersuchungen zu den Einflüssen von Agrippa auf Franck. Diese Lücke versucht dieser Aufsatz zu schließen. Beim Vergleich der metaphysischen Systeme von Franck und Agrippa stellt sich heraus, dass es bedeutende Einflüsse im Bereich der Seelenlehre und der Christologie gab. Sowohl Agrippa als auch Franck sind Anhänger der platonischen Lehre der drei (...) Seelenteile. Die Seele besteht nach dieser Lehre aus Geist, Seele und Körper. Der Geist ist der unsterbliche göttliche Teil im Menschen. Der Hauptunterschied zwischen Agrippa und Franck kann darin gesehen werden, dass Agrippas Synkretismus stärker den Neuplatonismus betont und Franck`s Synkretismus die Gnosis. Die Weltseele ergibt im Konzept von Franck nur wenig Sinn, während diese bei Agrippa ganz zentral ist. Franck lehnt den Gedanken ab, die Welt werde durch eine Vernunft geleitet. Sein pessimistisches Bild von der Welt und vom Menschen verträgt sich nicht mit diesem Gedanken. Da es keine Vernunft gibt, ist auch die Astrologie, die Mantik oder die Kabbalistik nicht wichtig für Franck. Daher ist es nicht verwunderlich, dass Franck nirgends die Occulta philosophia zitiert, sondern immer nur De Vantitate Scientiarum Der Synkretismus von Agrippa beinhaltet Astrologie, Mantik, Kabbala und Neuplatonismus. Am ehesten spielt bei Franck noch die Hermetik eine Rolle. Franck meint, Christus habe im Pimander mit Hermes Trismegistos kommuniziert. Diesen Gedanken findet man nicht nur bei Franck, sondern auch bei Agrippa. Die für Franck so wichtige Lehre des inneren Christus ist ebenfalls Teil der Seelenlehre von Agrippa. Wenn der Mensch seinen Geist oder seinen inneren Christus erkennt, dann erkennt er Gott. Die Untersuchung zeigt, dass Franck nur diejenigen Dinge von dem „weisen Agrippa“ übernommen hat, die in sein Konzept passen. (shrink)

Ovid versteht seine Metamorphosen als zusammenhängende Dichtung (perpetuum carmen). Für die Syrinx-Erzählung ist dieser Zusammenhang offensichtlich: Im ersten Buch wird erzählt, wie es zur Erfindung der Panflöte (Syrinx) gekommen ist, im elften Buch tritt Pan auf der Syrinx gegen Apollon an. Die unmittelbar anschließende Geschichte vom Barbier des Midas wird dagegen gegenwärtig nur selten mit der Syrinx verknüpft. Zu Unrecht, wie in diesem Aufsatz dargestellt werden soll. Denn diese Geschichte ist der eigentliche Schlusspunkt des musikalischen Wettstreits zwischen Pan und Apollon, (...) worin er sich, quasi in einer Zugabe, zugleich als Gott der Wahrheit präsentiert. Die vordergründig groteske Handlungsweise des Dieners ist durchgängig eine semantische Komposition zum Thema Syrinx. Nun wird Ovids Geschichte vom Barbier des Midas bekanntlich gerne mit dem Wort Binsenweisheit verknüpft und umgekehrt. Das geschieht durchaus unorthodox, nämlich nicht gestützt auf etymologische Wörterbücher, die meist andere Quellen bevorzugen, wenn sie die Wortbildung nicht gleich ungeklärt sein lassen. Zu dieser Verbindung gehört also eine gute Portion Einfalt. 2 Vor dem oben genannten Hintergrund müsste diese Beziehung zudem als besonders glückliche Fügung betrachtet werden. Ich kann nicht umhin, es so zu sehen und werde dafür argumentieren, dass Binsenweisheit ein Wort mit Geschichte ist, weil es ein Wort mit Geschichte ist. Gut, der Barbier des Midas wird darin zum Prototyp eines Whistleblowers. Das sieht nach einer hausgemachten Schwierigkeit aus, denn Binsenwahrheiten sind gerade keine Geheimnisse. Dieser Aspekt wird durch Bezug auf antike Interpreten, Ausonius und Persius, näher untersucht. All dies ist nicht möglich ohne kurze Streifzüge durch die Semantik von Binsenweisheit vermittels der stets griffbereiten Vergewisserungsformel Es ist eine Binsenweisheit, dass ... Zwischen Binsenwahrheit und Binsenweisheit wird im Aufsatz nicht weiter unterschieden. Wer möchte, kann sie jeweils Syrinx und Apollon, den beiden Hintergrundakteuren der Barbiergeschichte, zuordnen.

Der menschliche Verstand, sagt Kant, „kann nur d e n k e n und muss in den Sinnen die Anschauung suchen“ [KrV, §16]. Da der Verstand nur denken kann, ist denken und Anschauung suchen nicht zweierlei. Denn auch die Anschauung suchen muss man können. Daher sieht Kant das Besondere „unseres discursiven, der Bilder bedürftigen Verstandes (intellectus ectypus )“ [KdU §77] im „Vermögen, den Gegenstand sinnlicher Anschauung zu denken“ [KrV B75/A51]. Daher ist Verstand primär ein Erkenntnisvermögen. Denn ohne „den Stoff zum (...) Denken“ aus empirischer Anschauung „würde der Actus, Ich denke, doch nicht stattfinden“ [B423], und indem er sucht, findet er (cum quaerit, invenit): „Ich, der ich denke und anschaue, ist die Person“ [Preisschrift]. In diesem Aufsatz werden in einem ersten Ausblick einige grundlegende Textstellen auf dieser Basis analysiert. -/- Short summary: What is it like to be human understanding, according to Kant? Understanding is in search of intuition (intellectus ectypus quaerens sensibilitatem), and happens to be pretty successful, at least everywhere and anytime. The IQ (intellectus quaerens) project is a Kant interpretation which takes Kants talk of understanding seeking intuition as a serious thing in itself. Let‘s see how it works, with a few examples.

Albrecht von Wachters Studie Eine philosophische Untersuchung des Neuen Coronavirus (von Anfang Juni 2020) zufolge kann selbst ein gut informierter Laie erkennen, dass das Neuartige Coronavirus nicht besonders gefährlich ist. Ohne Widerspruch dazu lässt sich behaupten, dass ein Virus, das eine wichtige, sine qua non Bedingung einer weltweiten Krise ist, zurecht als hochgradig gefährlich beurteilt wird. Denn der Neuartige Coronavirus ist nicht nur gefährlich für die Gesundheit, sondern auch für Politik und Wirtschaft, wobei letzteres natürlich maßgeblich von der Beurteilung des (...) ersteren abhängt. Aber auch betreffend der Gefährlichkeit des Virus für ein und dasselbe kann man auf Basis derselben Informationen zu verschiedenen Ergebnissen kommen, und zwar, wenn verschieden Maß genommen wird, und dieses Maß ist der angewandte Gefahrenbegriff.

Menschen mussten schon immer auf der Hut sein und wir verstehen uns ganz gut auf Gefahren im allgemeinen. Von diesem allgemeinen Gefahrenbegriff ausgehend werden einige Binsenweisheiten zur Gefährlichkeit des Neuartigen Coronavirus vorgetragen. (shrink)

Upon separation of the protein from the nucleic acid component of tobacco mosaic virus by phenol, using a fast and gentle procedure, the nucleic acid is infective in assays on tobacco leaves. A series of qualitative and quantitative control experiments demonstrates that the biological activity cannot depend on residual proteins in the preparation, but is a property of isolated nucleic acid which is thus the genetic material of the virus.

Systems of logico-probabilistic (LP) reasoning characterize inference from conditional assertions interpreted as expressing high conditional probabilities. In the present article, we investigate four prominent LP systems (namely, systems O, P, Z, and QC) by means of computer simulations. The results reported here extend our previous work in this area, and evaluate the four systems in terms of the expected utility of the dispositions to act that derive from the conclusions that the systems license. In addition to conforming to the dominant (...) paradigm for assessing the rationality of actions and decisions, our present evaluation complements our previous work, since our previous evaluation may have been too severe in its assessment of inferences to false and uninformative conclusions. In the end, our new results provide additional support for the conclusion that (of the four systems considered) inference by system Z offers the best balance of error avoidance and inferential power. Our new results also suggest that improved performance could be achieved by a modest strengthening of system Z. (shrink)

Climate change and other harmful large-scale processes challenge our understandings of individual responsibility. People throughout the world suffer harms—severe shortfalls in health, civic status, or standard of living relative to the vital needs of human beings—as a result of physical processes to which many people appear to contribute. Climate change, polluted air and water, and the erosion of grasslands, for example, occur because a great many people emit carbon and pollutants, build excessively, enable their flocks to overgraze, or otherwise stress (...) the environment. If a much smaller number of people engaged in these types of conduct, the harms in question would not occur, or would be substantially lessened. However, the conduct of any particular person (and, in the case of climate change, of even quite large numbers of people) could make no apparent difference to their occurrence. My carbon emissions (and quite possibly the carbon emissions of much larger groups of people dispersed throughout the world) may not make a difference to what happens to anyone. When the conduct of some agent does not make any apparent difference to the occurrence of harm, but this conduct is of a type that brings about harm because many people engage in it, we can call this agent an overdeterminer of that harm, and their conduct overdetermining conduct. In this essay we explore the moral status of overdetermining harm. (shrink)

In this paper we discuss the new Tweety puzzle. The original Tweety puzzle was addressed by approaches in non-monotonic logic, which aim to adequately represent the Tweety case, namely that Tweety is a penguin and, thus, an exceptional bird, which cannot fly, although in general birds can fly. The new Tweety puzzle is intended as a challenge for probabilistic theories of epistemic states. In the first part of the paper we argue against monistic Bayesians, who assume that epistemic states can (...) at any given time be adequately described by a single subjective probability function. We show that monistic Bayesians cannot provide an adequate solution to the new Tweety puzzle, because this requires one to refer to a frequency-based probability function. We conclude that monistic Bayesianism cannot be a fully adequate theory of epistemic states. In the second part we describe an empirical study, which provides support for the thesis that monistic Bayesianism is also inadequate as a descriptive theory of cognitive states. In the final part of the paper we criticize Bayesian approaches in cognitive science, insofar as their monistic tendency cannot adequately address the new Tweety puzzle. We, further, argue against monistic Bayesianism in cognitive science by means of a case study. In this case study we show that Oaksford and Chater’s (2007, 2008) model of conditional inference—contrary to the authors’ theoretical position—has to refer also to a frequency-based probability function.

Indigenous and non-indigenous communities in Latin America make land claims and support them with a variety of arguments. Some, such as Zapatistas and the Mapuche, have appealed to the “ancestral” or “historical” connections between specific communities and the land. Other groups, such as MST in Brazil, have appealed to the extremely unequal distribution of the land and the effects of this on the poor; the land in this case is seen mainly as a means for securing a decent standard of (...) living for members of disadvantaged groups. Although there is a large literature on the history as well as the social and political dimensions of land contestations and conflicts in Latin America, the question of whether the land claims put forward by disadvantaged groups can be morally justified has not been adequately examined. In this essay, we investigate the scope and limits of appeals to what we shall call assistance-based, contribution-based, and benefitting-based moral reasons with respect to land claims made by these disadvantaged groups.

In this essay we argue that an agent’s failure to assist someone in need at one time can change the cost she can be morally required to take on to assist that same person at a later time. In particular, we show that the cost the agent can subsequently be required to take on to help the person in need can increase quite significantly, and can be enforced through the proportionate use of force. We explore the implications of this argument (...) for the duties of the affluent to address global poverty. (shrink)

Meta-induction, in its various forms, is an imitative prediction method, where the prediction methods and the predictions of other agents are imitated to the extent that those methods or agents have proven successful in the past. In past work, Schurz demonstrated the optimality of meta-induction as a method for predicting unknown events and quantities. However, much recent discussion, along with formal and empirical work, on the Wisdom of Crowds has extolled the virtue of diverse and independent judgment as essential to (...) maintenance of 'wise crowds'. This suggests that meta-inductive prediction methods could undermine the wisdom of the crowd inasmuch these methods recommend that agents imitate the predictions of other agents. In this article, we evaluate meta-inductive methods with a focus on the impact on a group's performance that may result from including meta-inductivists among its members. In addition to considering cases of global accessibility (i.e., cases where the judgments of all members of the group are available to all of the group's members), we consider cases where agents only have access to the judgments of other agents within their own local neighborhoods.

Schon der Titel von Kants Aufsatz kann als Hinweis darauf verstanden werden, zu lügen könne, wenn überhaupt, dann nur vermeintlich rechtens sein. Doch geht es um Lügen, die vermeintlich rechtens sein können, ist Kant notorisch unklar, mit Ausnahme dieses Aufsatzes. Denn die Klärung dieser Unklarheit ist gerade Kants systematischer Grund seiner Abfassung. Dieser These folgend wird versucht, Kants Argumentation in Anschluss an Die Metaphysik der Sitten nachzuzeichnen, und das, wofür argumentiert wird, ist: Genau dann, wenn einmal gesprochen werden muss, widerspricht (...) die Lüge, was auch ihr Inhalt sein mag, also formal, dem allgemeinen Sittengesetz in seinen inneren und äußeren Gesetzen. Der paradigmatische Fall für das menschliche Sprechenmüssen ist die äußere Gesetzgebung selbst. (shrink)

Crises in therapist-patient relationship can also become a challenge in clinical supervision. However, success and failure in establishing and maintaining constructive relationships in therapy and supervision is not only subject to a lucky fit of personal characteristics (therapist A gets along well/badly with client B; supervisee A gets along well/badly with supervisor C). Rather, we can identify determining field conditions in the overall therapeutic and supervisory situation for this outcome. We do not only focus on the persons involved, but also (...) on their environment, the task to be accomplished together, further framework conditions and the power relations resulting from their mutual influence-in the supervised case of therapy as well as in supervision itself. We want to examine the structure and dynamics of these relationships from a genuine Gestalt psychological perspective. What contributes to a cooperative atmosphere? When do goals get out of sight? What can make the atmosphere hostile? How do such developments become accessible in supervision? (shrink)

This book explores the nature of moral responsibilities of affluent individuals in the developed world, addressing global poverty and arguments that philosophers have offered for having these responsibilities. The first type of argument grounds responsibilities in the ability to avert serious suffering by taking on some cost. The second argument seeks to ground responsibilities in the fact that the affluent are contributing to such poverty. The authors criticise many of the claims advanced by those who seek to ground stringent responsibilities (...) to the poor by invoking these two types of arguments. It does not follow from this that the affluent are meeting responsibilities to the poor. The book argues that while people are not ordinarily required to make large sacrifices in assisting others in severe need, they are required to incur moderate costs to do so. If the affluent fail consistently to meet standards, this fact can substantially increase the costs they are required to bear in order to address it. (shrink)

In recent years it has often been claimed that policies such as subsidies paid to domestic producers by affluent countries and tariffs on goods produced by foreign producers in poorer countries violate important moral requirements because they do severe harm to poor people, even kill them. Such claims involve an empirical aspect—such policies are on balance very bad for the global poor—and a philosophical aspect—that the causal influence of these policies can fairly be characterized as doing severe harm and killing. (...) In this essay, we examine the philosophical aspect of this issue. We conclude that these policies do not do harm to the poor, but rather enable harm to them in various ways, and explore the moral implications of this fact. (shrink)

In previous work, we studied four well known systems of qualitative probabilistic inference, and presented data from computer simulations in an attempt to illustrate the performance of the systems. These simulations evaluated the four systems in terms of their tendency to license inference to accurate and informative conclusions, given incomplete information about a randomly selected probability distribution. In our earlier work, the procedure used in generating the unknown probability distribution (representing the true stochastic state of the world) tended to yield (...) probability distributions with moderately high entropy levels. In the present article, we present data charting the performance of the four systems when reasoning in environments of various entropy levels. The results illustrate variations in the performance of the respective reasoning systems that derive from the entropy of the environment, and allow for a more inclusive assessment of the reliability and robustness of the four systems.

Remittances are private financial transfers from migrant workers back to their countries of origin. These are typically intra-household transfers from members of a family who have emigrated to those who have remained behind. The scale of such transfers throughout the world is very large, reaching $338 billion U.S. in 20081—several times the size of overseas development assistance (ODA) and larger even than foreign direct investment (FDI). The data on migration and remittances is too poor to warrant very firm conclusions about (...) their effects—actual or potential—on poverty and development in poorer countries. We will however, present reasons that make it plausible to believe that remittances can contribute to poverty-reduction and promote development in poorer countries. Our main aim, however, is not to engage in detail with empirical debates about the effects of these transfers, but to establish moral grounds for favorable tax treatment on remittances on the assumption that they do have positive effects on receiving countries.

We describe a prediction method called "Attractivity Weighting" (AW). In the case of cue-based paired comparison tasks, AW's prediction is based on a weighted average of the cue values of the most successful cues. In many situations, AW's prediction is based on the cue value of the most successful cue, resulting in behavior similar to Take-the-Best (TTB). Unlike TTB, AW has a desirable characteristic called "access optimality": Its long-run success is guaranteed to be at least as great as the most (...) successful cue. While access optimality is a desirable characteristic, concerns may be raised about the short-term performance of AW. To evaluate such concerns, we here present a study of AW's short-term performance. The results suggest that there is little reason to worry about the short-run performance of AW. Our study also shows that, in random sequences of paired comparison tasks, the behavior of AW and TTB is nearly indiscernible. (shrink)

Traditionally, moral philosophers have distinguished between doing and allowing harm, and have normally proceeded as if this bipartite distinction can exhaustively characterize all cases of human conduct involving harm. By contrast, cognitive scientists and psychologists studying causal judgment have investigated the concept ‘enable’ as distinct from the concept ‘cause’ and other causal terms. Empirical work on ‘enable’ and its employment has generally not focused on cases where human agents enable harm. In this paper, we present new empirical evidence to support (...) the claim that some important cases in the moral philosophical literature are best viewed as instances of enabling harm rather than doing or allowing harm. We also present evidence that enabling harm is regarded as normatively distinct from doing and allowing harm when it comes to assigning compensatory responsibility. Moral philosophers should be exploring the tripartite distinction between doing harm, allowing harm, and enabling harm, rather than simply the traditional bipartite distinction. Cognitive scientists and psychologists studying moral judgment, who have so far largely adopted the bipartite distinction in this area of research, should likewise investigate the tripartite distinction.

Was ist Natur oder was könnte sie sein? Diese und weitere Fragen sind grundlegend für Naturdenken und -handeln. Das Lehr- und Studienbuch bietet eine historisch-systematische und zugleich praxisbezogene Einführung in die Naturphilosophie mit ihren wichtigsten Begriffen. Es nimmt den pluralen Charakter der Wahrnehmung von Natur in den philosophischen Blick und ist auch zum Selbststudium bestens geeignet.

There are numerous formal systems that allow inference of new conditionals based on a conditional knowledge base. Many of these systems have been analysed theoretically and some have been tested against human reasoning in psychological studies, but experiments evaluating the performance of such systems are rare. In this article, we extend the experiments in [19] in order to evaluate the inferential properties of c-representations in comparison to the well-known Systems P and Z. Since it is known that System Z and (...) c-representations mainly differ in the sorts of inheritance inferences they allow, we discuss subclass inheritance and present experimental data for this type of inference in particular.

In their paper Nothing but the Truth Andreas Pietz and Umberto Rivieccio present Exactly True Logic, an interesting variation upon the four-valued logic for first-degree entailment FDE that was given by Belnap and Dunn in the 1970s. Pietz & Rivieccio provide this logic with a Hilbert-style axiomatisation and write that finding a nice sequent calculus for the logic will presumably not be easy. But a sequent calculus can be given and in this paper we will show that a calculus for (...) the Belnap-Dunn logic we have defined earlier can in fact be reused for the purpose of characterising ETL, provided a small alteration is made—initial assignments of signs to the sentences of a sequent to be proved must be different from those used for characterising FDE. While Pietz & Rivieccio define ETL on the language of classical propositional logic we also study its consequence relation on an extension of this language that is functionally complete for the underlying four truth values. On this extension the calculus gets a multiple-tree character—two proof trees may be needed to establish one proof. (shrink)

Hilbert arithmetic in a wide sense, including Hilbert arithmetic in a narrow sense consisting by two dual and anti-isometric Peano arithmetics, on the one hand, and the qubit Hilbert space (originating for the standard separable complex Hilbert space of quantum mechanics), on the other hand, allows for an arithmetic version of Gentzen’s cut elimination and quantum measurement to be described uniformy as two processes occurring accordingly in those two branches. A philosophical reflection also justifying that unity by quantum neo-Pythagoreanism (...) links it to the opposition of propositional logic, to which Gentzen’s cut rule refers immediately, on the one hand, and the linguistic and mathematical theory of metaphor therefore sharing the same structure borrowed from Hilbert arithmetic in a wide sense. An example by hermeneutical circle modeled as a dual pair of a syllogism (accomplishable also by a Turing machine) and a relevant metaphor (being a formal and logical mistake and thus fundamentally inaccessible to any Turing machine) visualizes human understanding corresponding also to Gentzen’s cut elimination and the Gödel dichotomy about the relation of arithmetic to set theory: either incompleteness or contradiction. The metaphor as the complementing “half” of any understanding of hermeneutical circle is what allows for that Gödel-like incompleteness to be overcome in human thought. (shrink)

This contribution provides a transcription and translation of, and a commentary on, a letter of the German-Dutch-Japanese polymath Peter Hartzing to Gerhard Wolter Molanus, abbot of Loccum and famous collector of coins and medals. In the commentary, a survey of the life and intellectual endeavours of Hartzing is provided.

Review of Gerhard Richter's work on randomness in his recent abstract art paintings, compared with John Cage's work on randomness; the review asks about what randomness in representation qua art amounts to.

I argue that No-Ought-From-Is (in the sense that I believe it) is a relatively trivial affair. Of course, when people try to derive substantive or non-vacuous moral conclusions from non-moral premises, they are making a mistake. But No-Non-Vacuous-Ought-From-Is is meta-ethically inert. It tells us nothing about the nature of the moral concepts. It neither refutes naturalism nor supports non-cognitivism. And this is not very surprising since it is merely an instance of an updated version of the conservativeness of logic (in (...) a logically valid inference you don’t get out what you haven’t put in): so long as the expressions F are non-logical, you cannot get non-vacuous F-conclusions from non-F premises. However, the triviality of No-Non-Vacuous-Ought-From-Is is important and its non-profundity profound. No-Ought-From-Is is widely supposed to tell us something significant about the nature of the moral concepts. If, in fact, it tells us nothing, this is a point well worth shouting from the housetops. This brings me to my dispute with Gerhard Schurz who has proved a related version of No-Ought-From-Is, No-Ought-Relevant-Ought-From-Is, a proof which relaxes my assumption that ‘ought’ should not be treated as a logical constant. But if ought is not a logical expression then it does not really matter much that No-Ought-From-Is would be salvageable even if it were. Furthermore, Schurz’s proof depends on special features of the moral concepts and this might afford the basis for an abductive argument to something like non-cognitivism. As an error theorist, and therefore a cognitivist, I object. Finally I take a dim view of deontic logic. Many of its leading principles are false, bordering on the nonsensical, and even the reasonably plausible ones are subject to devastating counter-examples. (shrink)
