ZusammenfassungDie Geschichte der genetischen Pränataldiagnostik ist bislang als Teil der Geschichte der Humangenetik und deren Neuorientierung als klinisch-laborwissenschaftliche Disziplin in der zweiten Hälfte des 20. Jahrhunderts betrachtet worden. Anhand neuen Quellenmaterials soll in diesem Beitrag gezeigt werden, dass das Interesse an der Pränataldiagnostik in Westdeutschland auch im Kontext von Forschungen entstand, die sich mit Gefahren für den Menschen in der Umwelt befassten. Anhand der Debatten um die Einrichtung des DFG-Schwerpunktprogramms „Pränatale Diagnostik genetischer Defekte“ 1970 untersuchen wir, wie die Technik der (...) Amniozentese in Westdeutschland von einer interdisziplinären Forschungsgruppe eingeführt wurde, die sich mit Schädigungen des Organismus durch Strahlen, Arzneimittel und andere Gebrauchsstoffe und Konsumgüter befasste. In einer als ökologische Wende bezeichneten Zeit wachsenden Umweltbewusstseins, so unsere These, sollte durch die Förderung der Pränataldiagnostik eine wahrgenommene Lücke in der Prävention umweltbedingt auftretender genetischer Anomalien geschlossen werden. Für die Pränataldiagnostik als „Schutzmaßnahme“ sprach unter anderem ihre erwartete Finanzierung als Krankenkassenleistung im Zuge der Reform des Abtreibungsrechts. Erst in einem zweiten Schritt führten Veränderungen von Strukturen der Forschung, vor allem aber Erfahrungen in der gynäkologischen Praxis zu einer Neuausrichtung auf die Diagnostik und Prävention mehrheitlich erblicher oder spontan auftretender Anomalien. Die Pränataldiagnostik, so wie sie schließlich in Westdeutschland ab den frühen 1980er Jahren routinemäßig Einsatz fand, hatte mit Fragen der „Umwelt“ kaum noch zu tun. Diese Fallstudie zur Frühgeschichte der genetischen Pränataldiagnostik handelt von dem noch wenig untersuchten Verhältnis von humangenetischer Forschung, klinischer Praxis und Umweltforschung und hat zum weiteren Ziel, den bisher in anderen Kontexten beschriebenen Wandel von Perspektiven in der Vorsorge um 1970 zu beleuchten.

In this paper, I describe and discuss two mental phenomena which are somewhat neglected in the philosophy of mind: focused daydreaming and mind-wandering. My aim is to show that their natures are rather distinct, despite the fact that we tend to classify both as instances of daydreaming. The first difference between the two, I argue, is that, while focused daydreaming is an instance of imaginative mental agency, mind-wandering is not—though this does not mean that mind-wandering cannot involve mental agency at (...) all. This personal-level difference in agency and purposiveness has, furthermore, the consequence that instances of mind-wandering do not constitute unified and self-contained segments of the stream of consciousness—in stark contrast to focused daydreams. Besides, the two kinds of mental phenomena differ in whether they possess a narrative structure, and in how we may make sense of the succession of mental episodes involved. (shrink)

Sequence learning is fundamental to a wide range of cognitive functions. Explaining how sequences—and the relations between the elements they comprise—are learned is a fundamental challenge to cognitive science. However, although hundreds of articles addressing this question are published each year, the actual learning mechanisms involved in the learning of sequences are rarely investigated. We present three experiments that seek to examine these mechanisms during a typing task. Experiments 1 and 2 tested learning during typing single letters on each trial. (...) Experiment 3 tested for “chunking” of these letters into “words.” The results of these experiments were used to examine the mechanisms that could best account for them, with a focus on two particular proposals: statistical transitional probability learning and discriminative error-driven learning. Experiments 1 and 2 showed that error-driven learning was a better predictor of response latencies than either n-gram frequencies or transitional probabilities. No evidence for chunking was found in Experiment 3, probably due to interspersing visual cues with the motor response. In addition, learning occurred across a greater distance in Experiment 1 than Experiment 2, suggesting that the greater predictability that comes with increased structure leads to greater learnability. These results shed new light on the mechanism responsible for sequence learning. Despite the widely held assumption that transitional probability learning is essential to this process, the present results suggest instead that the sequences are learned through a process of discriminative learning, involving prediction and feedback from prediction error.

Our societies are marked not only by disagreements on the good life, but also by disagreements on justice. This motivates philosophers as divergent as John Gray and Chandran Kukathas to focus their normative political theories on peace instead of justice. In this article, I discuss how peace should be conceived if peace is to be a more realistic goal than justice, not presupposing any moral consensus. I distinguish two conceptions of peace to be found in the literature. One, ordinary peace, (...) conceives of peace as non-violent coexistence based on modus vivendi arrangements. Modus vivendi arrangements, in turn, are explained as a special kind of compromise. Ordinary peace does not presuppose any moral consensus and is therefore realistic, but at the same time it is too minimalist and undemanding to be satisfying. The other conception of peace, ambitious peace, can be found in Kukathas’s work. It is a conception of peace ‘beyond compromise’, not minimalist and undemanding, but, I will argue, not realistic because presupposing at least a second-order moral consensus. In the end, I advocate a division of labour between both conceptions of peace under the umbrella of an overarching ideal of peace. (shrink)

Need-claims are ubiquitous within moral and political theory. However, need-based theories are often criticized for being too narrow in scope and too focused on the material preconditions for leading a decent life for grounding a substantial theory of social justice. The aim of this paper is threefold. Firstly, it will investigate the nature and scope of needs by analysing existing conceptualizations of the idea of needs. In so doing, we will get a better understanding of needs, which will help us (...) to carve out the importance and singularity of basic need claims. Secondly, on the basis of the analysis of needs, it will argue for the concept of a fundamental interest in free social agency, which is much better suited than the idea of basic needs actually to ground a theory of social justice, as it highlights the social and institutional conditions for free agency. Thirdly, using the distinction between basic needs and fundamental interests, it will clarify their respective role in and importance for grounding moral principles. Overall, the paper offers a friendly critique of need-based theories, while arguing for a shift of focus to the idea of fundamental interests. (shrink)

Adorno notoriously asserted that there is no 'right' life in our current social world. This assertion has contributed to the widespread perception that his philosophy has no practical import or coherent ethics, and he is often accused of being too negative. Fabian Freyenhagen reconstructs and defends Adorno's practical philosophy in response to these charges. He argues that Adorno's deep pessimism about the contemporary social world is coupled with a strong optimism about human potential, and that this optimism explains his (...) negative views about the social world, and his demand that we resist and change it. He shows that Adorno holds a substantive ethics, albeit one that is minimalist and based on a pluralist conception of the bad - a guide for living less wrongly. His incisive study does much to advance our understanding of Adorno, and is also an important intervention into current debates in moral philosophy. (shrink)

Around the globe, economists affect markets by saying what markets are doing, what they should do, and what they will do. Increasingly, experimental economists are even designing real-world markets. But, despite these facts, economists are still largely thought of as scientists who merely observe markets from the outside, like astronomers look at the stars. Do Economists Make Markets? boldly challenges this view. It is the first book dedicated to the controversial question of whether economics is performative--of whether, in some cases, (...) economics actually produces the phenomena it analyzes.The book's case studies--including financial derivatives markets, telecommunications-frequency auctions, and individual transferable quotas in fisheries--give substance to the notion of the performativity of economics in an accessible, nontechnical way. Some chapters defend the notion; others attack it vigorously. The book ends with an extended chapter in which Michel Callon, the idea's main formulator, reflects upon the debate and asks what it means to say economics is performative.The book's insights and strong claims about the ways economics is entangled with the markets it studies should interest--and provoke--economic sociologists, economists, and other social scientists.In addition to the editors and Callon, the contributors include Marie-France Garcia-Parpet, Francesco Guala, Emmanuel Didier, Philip Mirowski, Edward Nik-Khah, Petter Holm, Vincent-Antonin Lépinay, and Timothy Mitchell.

The imagination poses fascinating philosophical questions across a range of subjects including philosophy of mind, aesthetics and epistemology. However, until now it has been a relatively neglected topic. How do acts of imagining differ from other mental episodes, such as perceptions or judgements? What kind of awareness is involved in imagining? Can imagining ground knowledge and if so, how reliable is it? Is there some unity to the various forms of imagining? In this book Fabian Dorsch considers these questions, (...) introducing and assessing all the main issues and arguments concerning imagination, including: episodic imagining imagining objects propositional imagining imagination and epistemology imagination and aesthetics imagination and cognitive science the unity of imagining. Including chapter summaries, annotated further reading and a glossary, _Imagination_ is an ideal starting point for anyone studying the philosophy of imagination for the first time as well as more advanced students and researchers in philosophy, psychology and related disciplines.

En el parágrafo §7 de Ser y Tiempo Heidegger distingue entre «vulgar», «formal» y «fenomenológico» a propósito del concepto de «fenómeno». El objetivo del presente artículo es mostrar, en primer lugar, que esta diferencia puede entenderse únicamente desde una previa aclaración de los motivos metodológicos del término. Se sostendrá, en segundo lugar, que todo tratamiento temático es al mismo tiempo un tratamiento metodológico, esto es, que la fenomenología hermenéutica de la existencia humana desarrolla y oculta un particular discurso del método.

This book explores the morality of compromising. The author argues that peace and public justification are values that provide moral reasons to make compromises in politics, including compromises that establish unjust laws or institutions. He explains how it is possible to have moral reasons to agree to moral compromises and he debates our moral duties and obligations in making such compromises. The book also contains discussions of the sources of the value of public justification, the relation between peace and justice, (...) the nature of modus vivendi arrangements and the connections between compromise, liberal institutions and legitimacy. In exploring the morality of compromising, the book thus provides some outlines for a map of political morality beyond justice. (shrink)

Sufficientarian libertarianism is a theory of justice that combines libertarianism’s focus on property rights and non-interference with sufficientarianism’s concern for the poor and needy. Persons are conceived as having stringent rights to direct their lives as they see fit, provided that everyone has enough to live a self-guided life. Yet there are different ways to combine libertarianism and sufficientarianism and hence different types of sufficientarian libertarianism. In the article I present and discuss three types, and I argue that the last (...) one overcomes the problems of the other two. The first type combines libertarianism with a sufficiency principle in what is sometimes called the ‘ethics of distribution’. The second incorporates modest welfare rights into a libertarian theory of justice. The third endorses a sufficientarian Lockean proviso for practices of private property within a libertarian theory of justice. I argue that it is superior to the others. (shrink)

Begründet und entfaltet wird ein Begriff des Spiels, der sich um Lockungen und Drohungen des Unerwarteten dreht. Das Autorenduo ordnet seine Theorie der ludischen Aktion in klassische Konzepte des Spiels ein sowie in den aktuellen Diskurs der Game Studies. Die phänomenale Mannigfaltigkeit des Spiels wird in historischer Perspektive skizziert und in systematischer Weise gegliedert. Die Autoren erläutern medientechnische und kommunikative Voraussetzungen des Booms der Computerspiele und reflektieren die Diskussion über Eskalationen ludischer Gewalt. Kritisch ausgeleuchtet werden Instrumentalisierungen des Spiels, die sich (...) unter dem Stichwort Gamification wachsender Beliebtheit erfreuen. Die auffällige Inflation der Spielmetapher wird in Zusammenhang gebracht mit ludischen Anmutungen in den sozialen Strukturen der modernen und digitalen Gesellschaft. Fabian Arlt, M. A., hat Medienmanagement studiert und promoviert im Studiengang Gesellschafts- und Wirtschaftskommunikation der Universität der Künste (UdK) in Berlin.

We report two experiments which tested whether cognitive capacities are limited to those functions that are computationally tractable (PTIME-Cognition Hypothesis). In particular, we investigated the semantic processing of reciprocal sentences with generalized quantifiers, i.e., sentences of the form Q dots are directly connected to each other, where Q stands for a generalized quantifier, e.g. all or most. Sentences of this type are notoriously ambiguous and it has been claimed in the semantic literature that the logically strongest reading is preferred (Strongest (...) Meaning Hypothesis). Depending on the quantifier, the verification of their strongest interpretations is computationally intractable whereas the verification of the weaker readings is tractable. We conducted a picture completion experiment and a picture verification experiment to investigate whether comprehenders shift from an intractable reading to a tractable reading which should be dispreferred according to the Strongest Meaning Hypothesis. The results from the picture completion experiment suggest that intractable readings occur in language comprehension. Their verification, however, rapidly exceeds cognitive capacities in case the verification problem cannot be solved using simple heuristics. In particular, we argue that during verification, guessing strategies are used to reduce computational complexity. (shrink)

From citizens paying taxes to employees following their bosses’ orders and kids obeying their parents, we take it for granted that a whole range of authorities have the power to impose duties on others. However, although authority is often accepted in practice, it looks philosophically problematic if we conceive persons as free and as equals. -/- In this short and accessible book, Fabian Wendt examines the basis of authority, discussing five prominent theories that try to explain how claims to (...) authority can be vindicated. Focusing in particular on the issue of how states can rightfully claim authority, he rigorously analyses the theories’ arguments and evaluates their strengths and weaknesses. He also debates anarchism as an alternative that should be taken seriously if no theory ultimately succeeds in explaining state authority. -/- This clear and engaging book will be essential reading for anyone grappling with the most fundamental questions of authority and obligation in political theory and political philosophy.

The republican ideal of freedom as non-domination stresses the importance of certain social relationships for a person’s freedom, showing that freedom is a social-relational state. While the idea of non-domination receives a lot of attention in the literature, republican theorists say surprisingly little about equality. My aim in this paper is therefore to carve out the contours of a republican conception of equality. In so doing, I argue that republican accounts of equality share a significant normative overlap with the idea (...) of ‘social equality’. However, closer analysis of Philip Pettit’s account of ‘expressive egalitarianism’ (which he sees as inherently connected to non-domination) and recent theories of social equality shows that republican non-domination – in contrast to what Pettit seems to claim – is not sufficient for securing (republican) social equality. In order to secure social equality for all, republicans would have to go beyond the ideal of freedom as non-domination. (shrink)

The extent and mechanisms through which religion intertwines with decision-making processes in family firms remain inadequately understood. Family firm owners, driven by their commitment to ethical business practices and the safeguarding of their socioemotional wealth, actively seek cues to inform their decision-making processes. This research demonstrates that, among these guiding cues, top-level executives’ perceived religiosity emerges as a relevant factor. Building upon the socioemotional wealth perspective and conducting a longitudinal analysis based on listed family firms between 2009 and 2018, our (...) findings reveal a positive association between family voting rights and the presence of board members perceived to be religious. Furthermore, this relationship is less pronounced if family firms operate in industries with high research and development intensity. Our study confirms that boards with high shares of religiously perceived directors are positively associated with the appointment of chief executive officers perceived to be religious during succession events. We thereby present a unique perspective that acknowledges perceived religiosity as a micro-level constituent shaping board membership and successor selection. This investigation captures the intricate interplay between religion and family firms under a socioemotional wealth umbrella, offering important insights to the family business ethics discourse. Our research also offers practical implications for board and leadership diversity management in family firms. (shrink)

This paper aims to explain the distinction between syllogisms and subsyllogisms in Stoic logic. Subsyllogisms replace at least one premise in a syllogism with a premise that is, according to Galen and Alexander, equipollent to the respective syllogistic premise. This equipollence is not synonymy of meaning between two linguistic expressions, but obtains between two propositions when they are true or false by the same standard. Subsyllogistic premises are simple propositions that are equipollent to the non-simple premises of the respective syllogisms. (...) For subsyllogistic premises that replace syllogistic premises consist of predicates combining with cases rather than of connectives or negations governing propositions. Because of this difference in their premises, subsyllogisms have a different logical form than syllogisms and are not formally valid. (shrink)

Este ensaio tem como objetivo afirmar a leitura e a escrita enquanto processo ativo tradutório, por meio da reimaginação do Texto de Partida As cidades invisíveis, redigido em 1972 pelo autor italiano Ítalo Calvino. O ensaio é tecido mediante a noção de fragmentos, tal como entendido por Tavares, em que a escrita se constitui como uma experimentação do pensamento. Toma como ponto de partida as pistas deixadas pelo viajante Marco Polo, na obra de Calvino, a qual foi lida e reinventada (...) pelos acadêmicos do Curso de Pedagogia de uma Instituição de Ensino Superior localizada no interior do Rio Grande do Sul. Um Roteiro de Procedimentos Escrileitores – escritura e leitura – das Cidades de Calvino foi disponibilizado aos estudantes, tendo como proposição mostrar nove regras, cujo objetivo consistiu em servir à operação tradutório-inventiva. A partir delas, os estudantes arriscaram uma leitura ativa e uma escritura viva, ou seja, uma escritura tradutória, que não visa à recuperação literal do texto, mas privilegia uma escrileitura inventiva e traduções-reinvenções. Como aporte teórico, o texto aproxima-se do pensamento da diferença, de Roland Barthes, de Gilles Deleuze, além das teorizações da tradução literária propostas por Haroldo de Campos. Trata-se de experimentar a prática da leitura e o ensaio da escrita gerando novas interpretações ao Texto de Partida. Nesse sentido, ler-e-escrever configuram-se como uma prática aberta, jamais definitiva e tampouco estática. Em síntese, o texto propõe defender que os Textos de Partida são sempre fisgados pelos processos tradutórios e, por isso, novamente reinventados via leitura e escrita em Textos de Chegada.

In the deep joint work Deleuze-Guattari there is the demand of consider it as a political theory of literature, a literary politics. The following paragraphs, to some extent respond to that demand, enroll the Deleuze-Guattari micropolitics in a concatenation between the revolutionary and artistic machines, in this case, literary. Considering this conjecture, in this article we propose to address the relationships between the concept of minor literature, the spatial dynamics and the informative order.

He identifies five central types of imagining that any unifying theory must accommodate and sets himself the task of determining whether any theory of what imagining consists in covers these five paradigms. Focussing on what he (...) takes to be the three main theories, and giving them each equal consideration, he faults the first two and embraces the third, which argues that imagining is a special form of mental agency.

A libertarian theory of justice holds that persons are self-owners and have the Hohfeldian moral power to justly acquire property rights in initially unowned external resources. Different variants of libertarianism can be distinguished according to their stance on the famous Lockean proviso. The proviso requires, in Locke’s words, to leave ‘enough and as good’ for others, and thus specifies limits on the acquisition of property. Left-libertarians accept an egalitarian interpretation of the proviso, ‘right-libertarians’ either reject any kind of proviso or (...) accept rather weak versions of it. In be-tween there is room for moderate interpretations of the proviso, and in particular for a sufficientarian interpretation: a ‘sufficiency proviso.’ The resulting theory of justice can be called ‘moderate libertarianism.’ In this article I make a case for moderate libertarianism, so understood. I argue that moderate libertarianism has advantages over both left- and right-libertarianism because it better coheres with the most plausible rationale for endorsing a libertarian theory of justice in the first place.

Public reason liberals from John Rawls to Gerald Gaus uphold a principle of public justification as a core commitment of their theories. Critics of public reason liberalism have sometimes conceded that there is something compelling about the idea of public justification. But so far there have not been many attempts to elaborate and defend a ‘comprehensive’ liberalism that incorporates a principle of public justification. This article spells out how public justifiability could be integrated into a comprehensive liberalism and defends the (...) claim that what is worthwhile about public justification can be extracted from public reason liberalism.

The problem of algorithmic fairness is typically framed as the problem of finding a unique formal criterion that guarantees that a given algorithmic decision-making procedure is morally permissible. In this paper, I argue that this is conceptually misguided and that we should replace the problem with two sub-problems. If we examine how most state-of-the-art machine learning systems work, we notice that there are two distinct stages in the decision-making process. First, a prediction of a relevant property is made. Secondly, a (...) decision is taken based (at least partly) on this prediction. These two stages have different aims: the prediction is aimed at accuracy, while the decision is aimed at allocating a given good in a way that maximizes some context-relative utility measure. Correspondingly, two different fairness issues can arise. First, predictions could be biased in discriminatory ways. This means that the predictions contain systematic errors for a specific group of individuals. Secondly, the system’s decisions could result in an allocation of goods that is in tension with the principles of distributive justice. These two fairness issues are distinct problems that require different types of solutions. I here provide a formal framework to address both issues and argue that this way of conceptualizing them resolves some of the paradoxes present in the discussion of algorithmic fairness. (shrink)

Martin Heideggers Abendgespräch in einem russischen Kriegsgefangenenlager zwischen einem Jüngeren und einem Älteren ist datiert auf den 8. Mai 1945, den Tag, an dem der Nationalsozialismus besiegt wurde. Der Schlüssel zum Verständnis des Textes ist ein Zitat aus dem klassischen daoistischen Buch Zhuangzi. Warum wendet sich Heidegger an diesem Tag der chinesischen Philosophie zu? Für den Philosophen und Sinologen Fabian Heubel birgt das Abendgespräch die einzigartige Gelegenheit, Heideggers Öffnung für östliches Denken kritisch zu erörtern. Zugleich zeigt sich die Kommunikationsverweigerung (...) zwischen Heidegger und Adorno in neuem Licht, indem das Buch beide mit Hilfe daoistischen paradoxen Denkens ins Gespräch kommen lässt. Im Kommunizieren dieser drei Momente tritt eine transkulturelle Kritik hervor, die durch geschichtliches Bewusstsein von Nöten gezeichnet ist. Heideggers Kehre nach Osten ist gescheitert. Andererseits gibt es keinen philosophischen Weg nach China, der an seinem Denken vorbeiführt."-- Back cover. (shrink)

According to Karen Neander’s causal-informational teleosemantics, the contents of perceptual states depend on the etiological response functions of sensory-perceptual systems. In this paper, I argue that this theory is, despite its virtues, unable to explain how humans and other animals are capable of perceiving properties with which no sensory-perceptual system has ever been confronted. After rejecting Neander’s own proposal in terms of second-order similarity and a proposal inspired by Ruth Millikan in terms of simplicity, I offer a solution which equates (...) functions with manifestations of dispositions that made a difference to evolutionary success. My suggestion is able to generate determinate and plausible contents for new perceptual states while still preserving the idea that etiological functions explain evolutionary success. (shrink)

This essay is based on the assumption that any ambition to ask how objects are actually able to appear is bound to a “speculative minimalism”. To be able to thematize “the intentional” as a form of our experience, our experience must not coincide with its intentional structure. The initial indication of this phenomenological finding is a constitutive and specific indeterminacy, which is co-realized in every determinacy within the intentional order. Marc Richir’s concept of a hyperbolic epoché is finally to be (...) brought into play as an approach to a contemporary, systematic integration of speculative minimalism and the transcendental ambition of phenomenology.

In Metaphysics Z 5, Aristotle discusses definition by addition and comes to accept it for per se accidents. I aim to explain how Aristotle could allow here certain statements by addition as valid definitions without contravening some relevant rules about repetition he established in the Organon, and also how this definition succeeds in blocking the regress he pointed out at 1030b35–1031a1. I conclude that ‘snub nose’ can be defined by a non-superfluous repetition, which in turn contains an explication of the (...) quality (‘snub’) along the line of the specification of the general property (‘concavity’).
