With the ever-growing quality of observational data in astronomy, the complexity of astrophysical models has been increasing in turn. This trend raises the question: Are there still reasons to prefer simpler models if the final goal is an actual model-target comparison? I argue for two aspects in which astrophysical research may favor models having reduced complexity: first, to address the problem of determining the values of adjustable parameters and, second, to pave the way for a validation of the model based (...) on the modeler’s understanding of the scope of the model and the critical processes on the target’s side.

This paper explores the epistemic status of models and simulations between theory, on the one hand, and observations, on the other. In particular, I will argue that the interpretation of an essentially invariant astrophysical model structure can change substantially over time. I will illustrate this claim using as an example the first 20 years (1985–2004) of development of the Paris-Durham shock code—a numerical model of slow interstellar shock waves (i.e. a disturbance of the medium that travel faster than the local (...) speed of sound). I will show that the model’s interpretation and, in particular, its underlying representational ideal—the modeler’s (often implicit) goal governing the development and the use of the model—changed notably during this period. Whereas the code was originally used in a purely exploratory fashion, it was later taken to represent and encompass the target phenomenon as completely as possible. It is noteworthy that during this transition the model’s change of epistemic status was never explicitly acknowledged or in any way articulated. However, the impetus for the change can, I claim, be found in the role that observational data came to play in the later publications. (shrink)

Sibylle Moser untersucht am Beispiel des Handlungsbegriffs die argumentative Komplexität der Empirischen Theorie der Literatur (ETL) und stellt den Entwurf einer konstruktivistischen Methodologie vor.

Food retailers are powerful actors of the agro-industrial food system. They exert strong lock-in effects that hinder transitions towards more sustainable agri-food systems. Indeed, their marketing practices generally result in excluding the most sustainable food products, such as local, low-input, small-scale farmers’ products. Recently in Belgium, several initiatives have been created to enable the introduction of local products on supermarket shelves. In this article, we study three of those initiatives to analyse if the development of local sourcing in supermarkets opens (...) up an opportunity for a transition towards more sustainable agri-food systems. We conceptualise transitions as a shift in governance and ethical values and adopt a pragmatist approach of ethics combined with the systemic perspective of transition studies, to evaluate the impact of these initiatives. Our analysis shows that they mainly contribute to the reproduction of the incumbent agri-food system. It also highlights that first, to be a driver for sustainability transitions, food ethics need to be systemic i.e. relate to a systemic understanding of problems and perspective of sustainability, including social justice. And second, it highlights that governance arrangements involving not only representative organisations of the various agri-food and non-agricultural actors, but also actors upholding ethical values that are currently missing in conventional supply chains and representing excluded and marginalised interests, favour the uptake of such systemic ethics by incumbent actors. Hence, systemic ethics and inclusive governance are key features for initiatives to contribute to a sustainability transition. (shrink)

This article presents an analytic critique of the predominant revisionist theoretical paradigm of just war (henceforth: revisionism). This is accomplished by means of a precise description and explanation of the practicability problem that confronts it, namely that soldiers that revisionism would deem “unjust” are bound to fail to fulfil the duties that revisionism imposes on them, because these duties are overdemanding. The article locates the origin of the practicability problem in revisionism’s overidealized conception of a soldier as an individual rational (...) agent analogous to the aggressor or defender in a case of lethal self-defense, who is capable of reflecting on the morality of his status in war and of the killing he performs and thus of recognizing his revisionist duties. Revisionism, however, ignores the following fact: Killing in war is not a natural human behavior. This is why training soldiers to kill is—and arguably always has been—a necessity for the existence of war and the killing that occurs in it. Moreover, this training involves a certain level of moral desensitization to violence whose goal is to prevent soldiers from thoroughly reflecting on the morality of the killing they engage in. Hence, war and killing can only exist if soldiers are trained in such a way that they do not reflect on whether they could be addressees of revisionist duties in the first place. This means that military training is a “constitutive condition” of soldiers and war, which is why it cannot excuse their noncompliance with revisionist duties, thus making these duties categorically overdemanding. The argument here draws on the paradigmatic example of modern US military killing conditioning (MC), but embeds it into a broader military-historical perspective that describes how soldiers have always needed to be mentally and morally influenced in order to enable war and killing. The article’s explanation of revisionism’s practicability problem has a constructive consequence for future theory-building in the ethics of war: It implies that a potentially revised ethical theory of war must necessarily analyze the institutions that allocate belligerent resources, if it aims to morally assess battlefield behavior in a practicable manner.

In the eighteenth century, the sciences and their applications adopted a new attitude based on quantification and, increasingly, on a notion of precision. Within this process, instruments played a significant role. However, while new devices such as the micrometer, telescope, and pendulum clock embodied a formerly unknown potential of precision, this could only be realized by defining a set of practices regulating their application and control. The paper picks up the case of pendulum clocks used in eighteenth-century observatories in order (...) to show the process of learning in the course of which the pendulum clock first became a precision instrument. By examining the results of an especially developed statistical analysis, conducted to compare the performance of eighteenth-century clocks, it highlights the diversity of conditions, attitudes, and manners of handling that are characteristic for the epoch. In this way, it underlines the necessity of standardization of timekeeping practices rather than exclusively focusing on the technological development of clocks. Ultimately, the paper discusses the role of makers and users in order to show the evolution of a “precision instrument.”. (shrink)

Investigators agree that hope is an important coping skill for patients. Hope is stronger than optimism and influences one's physical well being. Suggestions and strategies that can be used in the clinical setting to increase hope begin with an admission of its important role.

The daughter of French psychoanalyst Jacques Lacan tries to make sense of her relationship with her father. “When I was born, my father was already no longer there.” Sibylle Lacan's memoir of her father, the influential French psychoanalyst Jacques Lacan, is told through fragmentary, elliptical episodes, and describes a figure who had defined himself to her as much by his absence as by his presence. Sibylle was the second daughter and unhappy last child of Lacan's first marriage: the (...) fruit of despair (“some will say of desire, but I do not believe them”). Lacan abandoned his old family for a new one: a new partner, Sylvia Bataille (the wife of Georges Bataille), and another daughter, born a few months after Sibylle. For years, this daughter, Judith, was the only publicly recognized child of Lacan—even if, due to French law, she lacked his name. In one sense, then, A Father presents the voice of one who, while bearing his name, had been erased. If Jacques Lacan had described the word as a “presence made of absence,” Sibylle Lacan here turns to the language of the memoir as a means of piecing together the presence of a man who had entered her life in absence, and in his passing, finished in it. In its interplay of absence, naming, and the despair engendered by both, A Father ultimately poses an essential question: what is a father? This first-person account offers both a riposte and a complement to the concept (and the name) of the father as Lacan had defined him in his work, and raises difficult issues about the influence biography can have on theory—and vice versa—and the sometimes yawning divide that can open up between theory and the lives we lead.

Simple heuristics exploit basic human abilities, such as recognition memory, to make decisions based on sparse information. Based on the relative speed of recognizing two objects, the fluency heuristic infers that the one recognized more quickly has the higher value with respect to the criterion of interest. Behavioral data show that reliance on retrieval fluency enables quick inferences. Our goal with the present functional magnetic resonance imaging study was to isolate fluency-heuristic-based judgments to map the use of fluency onto specific (...) brain areas that might give a better understanding of the heuristic’s underlying processes. Activation within the claustrum for fluency heuristic decisions was found. Given that claustrum activation is thought to reflect the integration of perceptual and memory elements into a conscious gestalt, we suggest this activation correlates with the experience of fluency.

"Das Konzept der ›operativen Ontologien‹ ist nicht einfach zu verstehen. Dieser Artikel versucht Potenzial und Schranken dieser Idee auszuloten. Der methodische Ansatz der operativen Ontologie zielt darauf, dass das ›Ontische‹ im Sinne des phänomenal je Gegebenen das ›Ontologische‹ im Sinne der Erklärbarkeit und Verstehbarkeit von Welt bedingt und aus sich hervortreibt: Das Ontische gebiert das Ontologische. Was das bedeutet, wird einerseits anhand von Bernhard Siegerts Begriff ›Kulturtechnik‹ sowie andererseits anhand von Lorenz Engells Begriff der ›Ontographie‹ rekonstruiert sowie kritisch kommentiert. The (...) concept of ‘operative ontologies’ is not easy to understand. The article tries to explore the potential and limitations of this idea. The methodological approach of operative ontology aims at the fact that the ‘ontic’ (in the sense of the phenomenally given) deter- mines and produces the ‘ontological’ (in the sense of the comprehensibility of the world): The ontic gives birth to the ontological. The meaning of this statement is reconstructed with reference to Bernhard Siegert’s concept of ‘cultural technique’ as well as Lorenz Engell’s notion of ‘ontography’ and is further- more critically commented upon.

The article deals with Kant's understanding of personhood and autonomy. It highlights the connection of autonomy and human dignity within Kant's appreciation of morality, and indicates how his distinction between the empirical and transcendental spheres enables Kant to extend dignity even to humans who are not actually autonomous. Turning to contemporary approaches within ethics that refer to Kant but omit this transcendental framework, it defends the necessity of a trans-empirical frame within the Kantian system and hints at consequences for bioethics. (...) It concludes that Kant works with neither an absolutist notion of freedom in terms of solipsistic autarky, nor an empirical freedom and autonomy that begin and end at certain points of time.

In recent years feminists have begun arguing for various political conceptions of ‘care’. I have argued, by contrast, for the intimate connection between the women’s movement of the last half century, and the growing realization of the necessity of civic friendship as a condition for genuine justice. I only repeat the outlines of my argument here, for my goal is to look at various institutions which might help realize not merely ‘public care’ – contemporary theories of which I argue need (...) a far more careful normative account – but a civic friendship between all citizens. Indeed, I argue that the ideal of civic friendship provides that normative account of political care lacking in contemporary theories. (shrink)

ZusammenfassungDer Text versucht in Auseinandersetzung mit den Ansätzen von Jürgen Moltmann, Johann Baptist Metz und Odo Marquard und im Anschluss an lutherische Theologie zu einer Verhältnisbestimmung von Theodizeefrage und Kreuzestheologie zu gelangen. Dabei wird Luthers Einsicht fruchtbar gemacht, dass Gott verborgen im Leiden wirkt, das Leiden aber nicht zu seiner Wesenseigenschaft wird. Vielmehr eröffnet sich in der Klage des leidenden Menschen die Möglichkeit, das Leiden an Gott zu beenden und gegen Gott zu Gott zu fliehen. Von Luthers Kreuzestheologie her ist (...) eine gegenseitige Durchdringung von Theodizeefrage, Hamartiologie, Kreuzestheologie und Eschatologie anzumahnen. Gleichzeitig verhelfen Klage und Anklage dazu, sich aufgrund von erfahrenen Leiden nicht in sich selbst zu verschließen, sondern kontrafaktisch an Gott festzuhalten.SummaryDiscussing the thoughts of J. Moltmann, J. B. Metz and O. Marquard the essay attempts – whilst following Martin Luther's theologia crucis – to find a relation between the theodicy-question and the theology of the cross. For this concern it refers to the aspect that God acts in suffering in a hidden way but does not posses suffering as an intrinsic characteristic. Rather, the lament of suffering people address to God, as we find it in the Psalms, gives the opportunity of bringing suffering from God's hiddenness to an end and to “flee from God to God”. Returning to Luther's theologia crucis should lead to further reflections on theodicy, sin, theology of the cross and eschatology. At the same time, lamentation as bringing human suffering before God provides an aid for suffering people not to lock their suffering in themselves, but to maintain the relationship to God – even against the supposedly factual evidence of the experience of suffering.

ZUSAMMENFASSUNGIm Rekurs auf Luthers Verständnis der communicatio idiomatum, also der gegenseitigen Mitteilung und Partizipation von Göttlichem und Menschlichem in der Person Jesu Christi, versucht der Text eine Annäherung zu leisten an eine kommunikative theologische Anthropologie innerhalb einer relationalen und kommunikativen Ontologie. Mit einem solchen Konzept erscheint es als möglich, innerhalb der Debatte um Leib und Seele beziehungsweise Gehirn und Geist, die in den vergangenen Jahrzehnten aufgrund der Forschungsergebnisse der Neurowissenschaften von neuem in die öffentliche Aufmerksamkeit gerückt ist, zu einer Klärung (...) zu gelangen und sowohl einen Leib-Seele-Dualismus als auch eine naturalistische Reduzierung mentaler Prozesse auf rein physische Vorgänge zu vermeiden. Luthers Modell der communicatio idiomatum dient in diesem Zusammenhang als Strukturmodell für die Kommunikation von Mensch und Gott im Glauben und für die leib-seelische Existenz des Menschen selbst.SUMMARYThe article tries – in referring to Martin Luther's understanding of communicatio idiomatum, thus the communication of divine and human nature in the person of Jesus Christ – to outline a communicative anthropology and ontology, in order to help to clarify the body-mind-problem and to overcome both the body-mind-dualism and a naturalistic approach currently favoured by several neuroscientist concepts. In comparing Luther's view of the communication of immaterial and material processes within the person of Jesus Christ and his concept of communication that takes place between Christ and the believer, the essay concludes that Luther seems to conceive a constitutively relationally structured view of man. In taking this approach seriously, there could be a way for Christian theology to appropriately deal with the challenges caused by the contemporary neuroscientist debate. Following Luther's concept of communication within the person of Jesus Christ, of Christ and man and within man himself, this communicative concept could turn out to be helpful in outlining a relational and communicational theological anthropology.

This article notes differences in legislation in Germany and Great Britain regarding human embryo research and looks for an explanation in their divergent intellectual traditions. Whereas the German Stem Cell Act invokes an anthropological concept of human dignity to ground its ban on using embryos for research, there is no definition of what it means to be human in either the British Human Fertilisation and Embryology Act or in the advisory Warnock-Report. After studying the differences and providing some philosophical background, (...) the essay distinguishes two notions that are significant for understanding human dignity. It then proposes from a theological point of view a basic understanding within a relational anthropology, and comes to the conclusion that because of continuity in development and their relational constitution, humans embryos should be accepted as human from the moment of conception.

The study investigates the »Four Principles of Biomedical Ethics« published by Tom Beauchamp and James Childress with a particular concern for the principle of respect for autonomy. The leading question is in which philosophical background autonomy is dealt with by Beauchamp/childress and by the enlightenment philosopher Immanuel Kant, while the more emipirical theoretical framework of Beauchamp/childress and the rationalistic framework of Kant are being analyzed. After having considered the foundation of autonomy both in Beauchamp/childress and Kant, the study turns to (...) the relationship of autonomy and human dignity by exploring the implicit extension of autonomy, human dignity and being human, and asks which consequences have to be drawn from a theological point of view.

In international literature of the last decade, few genres have been as widely read or as intensely discussed as autofiction. Writers of autofiction use a variety of literary means to do what the novel has always done: to illuminate the private sphere. Yet, as this article argues, the idea of the private sphere underlying autofiction structurally differs from that of the fictional novel. Starting from a reading of Sheila Heti’s 2018 novel Motherhood and an analysis of its reception in various (...) YouTube formats, this article shows that the private sphere to which autofiction grants access is no longer framed as a refuge for the individual from the public. Instead, autofiction stages and reflects a model of privacy in which intense self-observation directly serves the creation of new social ties. Autofiction aesthetically reflects on interpersonal networking. Moreover, in dramatizing the crossing of boundaries between the fictional and non-fictional, and in breaking »the fourth wall,« it aesthetically recreates the forging of new network connections. The continued success of contemporary autofiction therefore needs to be understood against the backdrop of the structural transformation of the private sphere within the network society. (shrink)

A careful, theoretical clarification of gender roles has only recently begun in social and political philosophy. It is the aim of the following piece to reveal that an analysis of women’s traditional position - her distinctive activities, labor and surrounding sense of ‘mine’ - can not only make valuable contributions towards clarifying traditional property disputes, but may even provide elements for a new conception of ownership. By way of illustration, the article focusses on the influential work of John Rawls and (...) argues that - when Rawls’s own analysis and principles of justice are supplemented by an account of what is here called ‘reproductive labor’ - his theory in fact tends to a form of democratic socialism. Stated somewhat differently, my aim is to shift the terms of the property debate as posed by Rawls fromwithinhis own position. I hope to show that the real ownership question which now emerges is no longerwhether‘justice as fairness’ countenances a private property or socialist form of democracy, but what preciseformsuch a socialism should take.

O objetivo deste artigo é relacionar o ready-made de Duchamp – uma obra de arte que é idêntica a um objeto comum – com a história da arte que o precedeu e entender de que modo sua ruptura radical já estava dentro dessa história. Inicio com uma introdução ao e interpretação do ready-made. Em seguida, me respaldando em Gombrich, Greenberg e outros, examino os três tipos de arte na história propostos por Peter Bürger, focando na questão da realidade/irrealidade da obra, (...) aos poucos me aproximando da relação da obra com seu caráter de objeto. Meu ponto principal é que a bidimensionalidade do quadro reforça a existência da tela e assim também a relação de sua experiência com o mundo concreto em que o quadro se encontra, em contraposição a ilusão dramática do quadro tridimensional. A seguir, examino os impressionistas, onde se inicia um movimento de encontro à realidade da tela, que se radicaliza depois em variadas vertentes do modernismo, onde se encontra Duchamp. Tendo feito este percurso, examino o conceito de vanguarda de Bürger e sua relação com o que ele chama de práxis vital, o mundo fora do quadro ilusionista, que explico através da ideia de distração de Walter Benjamin. Aqui, sugiro pensar o ready-made como uma proposta de transposição da arte e sua teoria ao mundo "não-artístico" das coisas comuns. (shrink)
