This chapter examines the series of drastic epistemological and methodological transformations in the status of hypotheses in British natural philosophy during the seventeenth century. It explains that hypotheses played a rather marginal role in Francis Bacon's methodological thought because he believed they lacked any physical content, although they occupied a centre stage in the Bacon-inspired natural philosophy program of Robert Boyle and Robert Hooke. The chapter mentions that Boyle and Hooke provided a new definition of hypothesis, which is (...) that of something conceived of as causally sufficient and probable explications of natural phenomena that stand in an evidential relation to the natural phenomena they serve to elucidate.

Regular musical activity as a complex multimodal lifestyle activity is proposed to be protective against age-related cognitive decline and Alzheimer’s disease. This cross-sectional study investigated the association and interplay between musical instrument playing during life, multi-domain cognitive abilities and brain morphology in older adults from the DZNE-Longitudinal Cognitive Impairment and Dementia Study study. Participants reporting having played a musical instrument across three life periods were compared to controls without a history of musical instrument playing, well-matched for reserve proxies of education, (...) intelligence, socioeconomic status and physical activity. Participants with musical activity outperformed controls in global cognition, working memory, executive functions, language, and visuospatial abilities, with no effects seen for learning and memory. The musically active group had greater gray matter volume in the somatosensory area, but did not differ from controls in higher-order frontal, temporal, or hippocampal volumes. However, the association between gray matter volume in distributed frontal-to-temporal regions and cognitive abilities was enhanced in participants with musical activity compared to controls. We show that playing a musical instrument during life relates to better late-life cognitive abilities and greater brain capacities in OA. Musical activity may serve as a multimodal enrichment strategy that could help preserve cognitive and brain health in late life. Longitudinal and interventional studies are needed to support this notion. (shrink)

Spatestens seit dem emotional turn in den Kulturwissenschaften zu Anfang dieses Jahrhunderts ist die Leibphanomenologie von Hermann Schmitz kein Geheimtipp mehr. Die Zahl der Studien, die sich mit ihr auseinandersetzen, ist heute kaum uberschaubar. Der Band versucht nach knapp einem halben Jahrhundert Wirkungsgeschichte eine Art Zwischenbilanz zu ziehen. Er fragt, inwiefern und in welchen Kontexten sich die von Schmitz erarbeiteten Kategorien des eigenleiblichen Spurens bewahrt haben. Die Beitrage erortern die gespurte Leiblichkeit in ihrer Verflechtung mit Sachverhalten wie Geschichte, Kultur, Person, (...) Geschlecht sowie als Aktionsfeld leiblicher Kommunikation und zeugen davon, dass das von Schmitz begonnene Projekt uber die Philosophie hinaus auch von anderen Wissenschaften stetig erganzt und weiterentwickelt wird. Vor dem Hintergrund eines sich am Leitmodell des sicht- und tastbaren Korpers orientierenden Denkens konnten sprachliche Ausdrucke fur leibliches Erleben nur als Skandal der Metapher (Strub) begriffen werden. Die Leibphanomenologie bietet dagegen einen alternativen Zugang, dem aber der Korper, wie Schmitz sagt, zum Skandal wird. Diesem schwierigen Verhaltnis von Leib und Korper geht der Band nach, um das Skandalose theoretisch einzuholen. Mit Beitragen von Kerstin Andermann, Undine Eberlein, Thomas Fuchs, Ute Gahlings, Robert Gugutzer, Christian Julmi / Ewald Scherm, Steffen Kammler, Gudula Linck, Gesa Lindemann, Isabella Marcinski, Jan Slaby, Hermann Schmitz und Jens Soentgen.

A philosopher argues that state-sponsored cyberattacks against central military or civilian targets are always acts of war. What is this philosopher doing? According to conceptual analysts, the philosopher is making a claim about our concept of war. According to philosophical realists, the philosopher is making a claim about war per se. In a quickly developing literature, a third option is being explored: the philosopher is engineering the concept of war. On this view, the philosopher is making a proposal about which (...) concept we should have – even if it deviates from the extant concept, and even if it does not capture ‘what war really is’. The activity or method of proposing such revisionary definitions, as well as the metaphilosophical reflection on it, has become known as conceptual engineering. (shrink)

Conceptual engineering concerns the assessment and improvement of our concepts. But how can proposals to engineer concepts be implemented in the real world? This is known as the implementation challenge to conceptual engineering. In this paper, I am concerned with the meta-philosophical implications of the implementation challenge. Specifically, must we overcome the implementation challenge prior to undertaking conceptual engineering? Some critics have recently answered this question affirmatively. I intend to show that they are mistaken. I argue as follows. First, successful (...) implementation is not an integral part of conceptual engineering. Second, the idea that the value of conceptual engineering relies on successful implementation is in tension with widespread assumptions about normative theorizing. (shrink)

Bayesian approaches for estimating multilevel latent variable models can be beneficial in small samples. Prior distributions can be used to overcome small sample problems, for example, when priors that increase the accuracy of estimation are chosen. This article discusses two different but not mutually exclusive approaches for specifying priors. Both approaches aim at stabilizing estimators in such a way that the Mean Squared Error of the estimator of the between-group slope will be small. In the first approach, the MSE is (...) decreased by specifying a slightly informative prior for the group-level variance of the predictor variable, whereas in the second approach, the decrease is achieved directly by using a slightly informative prior for the slope. Mathematical and graphical inspections suggest that both approaches can be effective for reducing the MSE in small samples, thus rendering them attractive in these situations. The article also discusses how these approaches can be implemented in Mplus. (shrink)

This paper deals with the question of whether nature sports are to be counted among the (traditional) sports and Kevin Krein’s recent argument, based on sporting excellence, as to why they should. Krein argues that sports as such are ultimately about sporting excellence and because both so-called traditional sports and nature sports fulfil that criterion, nature sports belong in the sport domain. Here, I show that Krein’s argument rests on an equivocation between two concepts of sporting excellence. Sporting excellence in (...) traditional sports is connected to sporting success. Here agon (contest or competition) dictates or frames areté (striving for excellence). This is not the case for sporting excellence in nature sports, as these are not competitions. We are dealing with two different concepts of sporting excellence and Krein’s argument, based on sporting excellence, must be rejected. It gives no basis for including nature sports in the sport domain. (shrink)

Connecting human minds to various technological devices and applications through brain-computer interfaces (BCIs) affords intriguingly novel ways for humans to engage and interact with the world. Not only do BCIs play an important role in restorative medicine, they are also increasingly used outside of medical or therapeutic contexts (e.g., gaming or mental state monitoring). A striking peculiarity of BCI technology is that the kind of actions it enables seems to differ from paradigmatic human actions, because, effects in the world are (...) brought about by devices such as robotic arms, prosthesis, or other machines, and their execution runs through a computer directed by brain signals. In contrast to usual forms of action, the sequence does not need to involve bodily or muscle movements at all. A motionless body, the epitome of inaction, might be acting. How do theories of action relate to such BCI-mediated forms of changing the world? We wish to explore this question through the lenses of three perspectives on agency: subjective experience of agency, philosophical action theory, and legal concepts of action. Our analysis pursues three aims: First, we shall discuss whether and which BCI-mediated events qualify as actions, according to the main concepts of action in philosophy and law. Secondly, en passant, we wish to highlight the ten most interesting novelties or peculiarities of BCI-mediated movements. Thirdly, we seek to explore whether these novel forms of movement may have consequences for concepts of agency. More concretely, we think that convincing assessments of BCI-movements require more fine-grained accounts of agency and a distinction between various forms of control during movements. In addition, we show that the disembodied nature of BCI-mediated events causes troubles for the standard legal account of actions as bodily movements. In an exchange with views from philosophy, we wish to propose that the law ought to reform its concept of action to include some, but not all, BCI-mediated events and sketch some of the wider implications this may have, especially for the venerable legal idea of the right to freedom of thought. In this regard, BCIs are an example of the way in which technological access to yet largely sealed-off domains of the person may necessitate adjusting normative boundaries between the personal and the social sphere.

Worte verletzen und kränken. Woher aber kommt diese Verletzungsmacht? Während in der deutschsprachigen Philosophie Sprache meist als Gegenmittel zur Gewalt begriffen wird, hat die US-amerikanische Debatte um "hate speech" gezeigt, dass das Sprechen Gewalt nicht nur androhen oder verhindern, sondern selbst eine Form von Gewaltausübung sein kann. Wie nun sind sprachliche Verletzung, Ausgrenzung und Missachtung zu erklären und zu verstehen? Aus der Sicht verschiedener Disziplinen untersuchen die Beiträge dieses Bandes, welcher Logik, Grammatik und Rhetorik unser verletzendes Sprechen gehorcht. Mit Beiträgen (...) von u.a.

The idea of "spirit" has manifold meanings and plays a crucial role in Early Modern medicine, psychology, religion, natural philosophy, and cosmology. This book contains twenty papers, written by international experts; it explores how those disciplines conceived of the spirits and shows that knowledge of the spirits is an essential prerequisite for the understanding of Renaissance literature and music. The volume focuses on the way in which the spirits act upon the soul's perception, imagination, and cognition, and on the cultural (...) practices which aim to use, purge, or ban the spirits.

In this article, we draw on established views of CSR dysfunctionalities to show how and why CSR is regularly observed to be both shaped by and supportive of capitalism. We proceed to show that these dysfunctionalities are maintained by both the pro- and anticapitalist approaches to CSR, both of which imply an ill-defined separation of the economy and society as well an overly strong problem or solution focus on political and economic issues. Finally, we present a post-capitalist approach to CSR (...) that overcomes (1) the ill-defined separation of the economy and society, (2) the capitalist bias towards economic rationalities, and (3) the overidentification of society with its political system; this approach thus helps to manage the abovementioned CSR dysfunctionalities.

Genes induced by the plant hormone auxin are probably involved in the execution of vital cellular functions and developmental processes. Experimental approaches designed to elucidate the molecular mechanisms of auxin action have focused on auxin perception, genetic dissection of the signaling apparatus and specific gene activation. Auxin‐responsive promoter elements of early genes provide molecular tools for probing auxin signaling in reverse. Functional analysis of several auxin‐specific promoters of unrelated early genes suggests combinatorial utilization of both conserved and variable elements. These (...) elements are arranged into autonomous domains and the combination of such modules generates uniquely composed promoters. Modular promoters allow for auxin‐mediated transcriptional responses to be revealed in a tissue‐ and development‐specific manner. (shrink)

La notion de "Bildung" (culture) de Humboldt au National-socialisme dans les états allemands modernes.

Our outline points out three aspects of a new post-modern methodology in psychology: liberal, pluralistic, and more tolerant: liberal because it rejects rules that are too strict in favor of more freedom in the choice of method, pluralistic because it conveys an “almost anything goes” attitude toward methods, and more tolerant because mutual tolerance among researchers is vital for a pluralism of methods. Psychological phenomena are complex and can best be understood by using different methods. However, to get things working, (...) tolerance must actively be lived. Of course, much depends on our own willingness as researchers but also on the system’s arrangements. Psychology could be more colorful, and we could all have more fun if we were to be more committed to such a methodology. (shrink)

For the living, death has a moral dimension. When we confront death and dying in our own lives and in the lives of others, we ask questions about the good, right, and fitting as they relate to our experiences of human mortality. When others die, the living are left with moral questions--questions that often generate personal inquiry as to whether a particular death was "good" or whether it was tragic, terrifying, or peaceful. In The Ethics of Death, the authors, one (...) a philosopher and one a religious studies scholar, undertake an examination of the deaths that we experience as members of a larger moral community. Their respectful and engaging dialogue highlights the complex and challenging issues that surround many deaths in our modern world and helps readers frame thoughtful responses. Unafraid of difficult topics, Steffen and Cooley fully engage suicide, physician-assisted suicide, euthanasia, capital punishment, abortion, and war as areas of life where death poses moral challenges." -- Publisher's description.

This paper discusses the logical space of alternative conceptual engineering projects, with a specific focus on (1) the processes, (2) the targets and goals, and (3) the methods of such projects. We present an overview of how these three aspects interact in the contemporary literature and discuss those alternative projects that have yet to be explored based on our suggested typology. We show how choices about each element in a conceptual engineering project constrain the possibilities for the others, thereby giving (...) rise to distinct groupings of possible projects under the banner of conceptual engineering. We conclude with a critical reflection on the potential ethical issues that arise as a result of effectively putting conceptual engineering into practice. (shrink)

The abstract structure of inquiry - the process of acquiring and changing beliefs about the world - is the focus of this book which takes the position that the "pragmatic" rather than the "linguistic" approach better solves the philosophical problems about the nature of mental representation, and better accounts for the phenomena of thought and speech. It discusses propositions and propositional attitudes (the cluster of activities that constitute inquiry) in general and takes up the way beliefs change in response to (...) potential new information, suggesting that conditional propositions should be understood as projections of epistemic policies onto the world.Robert C.

Unlike conceptual analysis, conceptual engineering does not aim to identify the content that our current concepts do have, but the content which these concepts should have. For this method to show the results that its practitioners typically aim for, being able to change meanings seems to be a crucial presupposition. However, certain branches of semantic externalism raise doubts about whether this presupposition can be met. To the extent that meanings are determined by external factors such as causal histories or microphysical (...) structures, it seems that they cannot be changed intentionally. This paper gives an extended discussion of this ‘externalist challenge’. Pace Herman Cappelen’s recent take on this issue, it argues that the viability of conceptual engineering crucially depends on our ability to bring about meaning change. Furthermore, it argues that, contrary to first appearance, causal theories of reference do allow for a sufficient degree of meaning control. To this purpose, it argues that there is a sense of what is called ‘collective long-range control’, and that popular versions of the causal theory of reference imply that people have this kind of control over meanings.

Is the endeavour to restore perceptive brain functions by electronic implants the first step on the way to create bionic cyborgs? Can we augment or multiply our senses by directly contacting computer chips to the brain? Will bio-implants influence and permanently change human psyche?

Currently, electronic agents are being designed and implemented that, unprecedentedly, will be capable of performing legally binding actions. These advances necessitate a thorough treatment of their legal consequences. In our paper, we first demonstrate that electronic agents behave structurally similar to human agents. Then we study how declarations of intention stated by an electronic agent are related to ordinary declarations of intention given by natural persons or legal entities, and also how the actions of electronic agents in this respect have (...) to be classified under German law. We discuss four different approaches of classifying agent declarations. As one of these, we propose the concept of an electronic person (i.e., agents with limited liability), enrolment of agents into an agent register, and agent liability funds as means to serve the needs of all contracting parties.

Robert B. Brandom is one of the most original philosophers of our day, whose book Making It Explicit covered and extended a vast range of topics in metaphysics, epistemology, and philosophy of language--the very core of analytic philosophy. This new work provides an approachable introduction to the complex system that Making It Explicit mapped out. A tour of the earlier book's large ideas and relevant details, Articulating Reasons offers an easy entry into two of the main themes of Brandom's (...) work: the idea that the semantic content of a sentence is determined by the norms governing inferences to and from it, and the idea that the distinctive function of logical vocabulary is to let us make our tacit inferential commitments explicit. Brandom's work, making the move from representationalism to inferentialism, constitutes a near-Copernican shift in the philosophy of language--and the most important single development in the field in recent decades. Articulating Reasons puts this accomplishment within reach of nonphilosophers who want to understand the state of the foundations of semantics. Table of Contents: Introduction 1. Semantic Inferentialism and Logical Expressivism 2. Action, Norms, and Practical Reasoning 3. Insights and Blindspots of Reliabilism 4. What Are Singular Terms, and Why Are There Any? 5. A Social Route from Reasoning to Representing 6. Objectivity and the Normative Fine Structure of Rationality Notes Index Displaying a sovereign command of the intricate discussion in the analytic philosophy of language, Brandom manages successfully to carry out a program within the philosophy of language that has already been sketched by others, without losing sight of the vision inspiring the enterprise in the important details of his investigation ' Using the tools of a complex theory of language, Brandom succeeds in describing convincingly the practices in which the reason and autonomy of subjects capable of speech and action are expressed. --J'rgen Habermas.

Zusammenfassung Der vorliegende Beitrag lädt zur Beschäftigung mit dem Advent ein. Er knüpft zum Einstieg bei einem für dieses Vorhaben geeigneten Advents- und Weihnachtslied an: bei Alle Jahre wieder. Das Gedicht, das diesem populären Lied zugrunde liegt, entpuppt sich im Gegenlicht der religionsphilosophischen Einlassungen von Jean-Luc Nancy und Giorgio Agamben als kompaktes poetisches Pendant zu einer Theologie des Advents, die getragen wird von der Struktur eines dem Erscheinen zuvorkommenden (Heran-)Kommens und die in dieser prozessierenden Präsenz (man könnte auch sagen: dieser (...) Ereignishaftigkeit) eine Grundfigur des (christlichen) Lebens erkennt. (shrink)
