Farben sind für uns sowohl objektive, als auch phänomenale Eigenschaften. In seinem Buch argumentiert Fabian Dorsch, daß keine ontologische Theorie der Farben diesen beiden Seiten unseres Farbbegriffes gerecht werden k ann. Statt dessen sollten wir akzeptieren, daß letzterer sich auf zwei verschiedene Arten von Eigenschaften bezieht: die repräsentierten Reflektanzeigenschaften von Gegenständen und die qualitativen Eigenschaften unserer Farbwahrnehmungen, die als sinnliche Gegebenheitsweisen ersterer fungieren. Die Natur der Farben gibt einen detaillierten Überblick über die zeitgenössischen philosophischen und naturwissenschaftlichen Theorien der Farben (...) und bietet sich aufgrund seines systematischen und umfassenden Charakters auch als ein seminar- oder vorlesungsbegleitendes Textbuch an.

The scientific and practical fields—especially high-performance sports—increasingly request a stronger focus be placed on individual athletes in human movement science research. Machine learning methods have shown efficacy in this context by identifying the unique movement patterns of individuals and distinguishing their intra-individual changes over time. The objective of this investigation is to analyze biomechanically described movement patterns during the fatigue-related accumulation process within a single training session of a high number of repeated executions of a ballistic sports movement—specifically, the frontal (...) foot kick (mae-geri) in karate—in expert athletes. The two leading research questions presented for consideration are (1) Can characteristics of individual movement patterns be observed throughout the entire training session despite continuous changes, i.e., even as fatigue-related processes increase? and (2) How do intra-individual movement patterns change as fatigue-related processes increase throughout a training session? Sixteen expert karatekas performed 606 frontal foot kicks directed toward an imaginary target. The kicks were performed in nine sets at 80% (K-80) of the self-experienced maximal intensity. In addition, six kicks at maximal intensity (K-100) were performed after each of the nine sets. Between the sets, the participants took a 90-s break. Three-dimensional full-body kinematic data of all kicks were recorded with 10 infrared cameras. The normalized waveforms of nine upper- and lower-body joint angles were classified using a supervised machine learning method (support vector machine). The results of the classification revealed a disjunct distinction between the kinematic movement patterns of individual athletes. The identification of unique movement patterns of individual athletes was independent of the intensity and the degree of fatigue-related processes. In other words, even with the accumulation of fatigue-related processes, the unique movement patterns of an individual athlete can be clearly identified. During the training session, changes in intra-individual movement patterns could also be detected, indicating the occurrence of adaptations in individual movement patterns throughout the fatigue-related accumulation process. The results suggest that these adaptations can be modeled in terms of changes in patterns rather than increasing variance. Practical consequences are critically discussed. (shrink)

The article comments on the view of authors Johannes Fabian and Emmanuel Levinas on the Africanist research and social praxis in Africa. Fabian determined his ideas within anthropology, while Levinas used philosophy and ethics. The author emphasized that their reflections articulate the need for a dialogical approach in Africanist scholarship. He argued that coevalness is not enough to redress the effects of colonial and postcolonial objectification of human existence in the country.

Effectiveness is a key criterion in assessing the justification of antibiotic resistance interventions. Depending on an intervention’s effectiveness, burdens and costs will be more or less justified, which is especially important for large scale population-level interventions with high running costs and pronounced risks to individuals in terms of wellbeing, integrity and autonomy. In this paper, we assess the case of routine hospital screening for multi-drug-resistant Gram-negative bacteria (MDRGN) from this perspective. Utilizing a comparison to screening programs for Methicillin-Resistant Staphylococcus aureus (...) (MRSA) we argue that current screening programmes for MDRGN in low endemic settings should be reconsidered, as its effectiveness is in doubt, while general downsides to screening programs remain. To accomplish justifiable antibiotic stewardship, MDRGN screening should not be viewed as a separate measure, but rather as part of a comprehensive approach. The program should be redesigned to focus on those at risk of developing symptomatic infections with MDRGN rather than merely detecting those colonised. (shrink)

In the last ten or fifteen years, realism has emerged as a distinct approach in political theory. Realists are skeptical about the merits of abstract theories of justice. They regard peace, order, and stability as the primary goals of politics. One of the more concrete aims of realists is to develop a realist perspective on legitimacy. I argue that realist accounts of legitimacy are unconvincing, because they do not solve what I call the “puzzle of legitimacy”: the puzzle of how (...) some persons can have the right to rule over others, given that all persons are equals. I focus on the realist accounts of legitimacy developed by Bernard Williams and John Horton. (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.

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)

Robert Nozick and Eric Mack have tried to show that a minimal state could be just. A minimal state, they claim, could help to protect people’s moral rights without violating moral rights itself. In this article, I will discuss two challenges for defenders of a minimal state. The first challenge is to show that the just minimal state does not violate moral rights when taxing people and when maintaining a monopoly on the use of force. I argue that this challenge (...) can be met. The second challenge is to show that the just min-imal state has political authority including, most importantly, the moral power to im-pose duties on citizens. I argue that both Nozick and Mack lack the resources to meet that challenge, and that political authority cannot be deflated. This is an important prob-lem because a lack of political authority also undermines a state’s justness. (shrink)

From a left-libertarian perspective, it seems almost impossible for states to acquire political authority. For that reason, left-libertarians like Peter Vallentyne understandably hope that states without political authority could nonetheless implement left-libertarian justice. Vallentyne has argued that one can indeed assess a state’s justness without assessing its political authority. Against Vallentyne, I try to show that states without political authority have to be judged unjust even if they successfully promote justice. The reason is that institutions can be unjust independently from (...) what they achieve or do: they can be ‘intrinsically unjust’. Institutions, I argue, are intrinsically unjust when they have legal liberties and powers without having the corresponding moral liberties and powers. States without political authority are intrinsically unjust in that sense. Hence the issues of a state’s justness and a state’s political authority cannot be dealt with separately. This is a problem not only for left-libertarians but for ‘philosophical anarchism’ more generally. (shrink)

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.

A growing body of evidence in cognitive psychology and neuroscience suggests a deep interconnection between sensory-motor and language systems in the brain. Based on recent neurophysiological findings on the anatomo-functional organization of the fronto-parietal network, we present a computational model showing that language processing may have reused or co-developed organizing principles, functionality, and learning mechanisms typical of premotor circuit. The proposed model combines principles of Hebbian topological self-organization and prediction learning. Trained on sequences of either motor or linguistic units, the (...) network develops independent neuronal chains, formed by dedicated nodes encoding only context-specific stimuli. Moreover, neurons responding to the same stimulus or class of stimuli tend to cluster together to form topologically connected areas similar to those observed in the brain cortex. Simulations support a unitary explanatory framework reconciling neurophysiological motor data with established behavioral evidence on lexical acquisition, access, and recall. (shrink)

The uncertainty associated with paradigmatic families has been shown to correlate with their phonetic characteristics in speech, suggesting that representations of complex sublexical relations between words are part of speaker knowledge. To better understand this, recent studies have used two-layer neural network models to examine the way paradigmatic uncertainty emerges in learning. However, to date this work has largely ignored the way choices about the representation of inflectional and grammatical functions in models strongly influence what they subsequently learn. To explore (...) the consequences of this, we investigate how representations of IFS in the input-output structures of learning models affect the capacity of uncertainty estimates derived from them to account for phonetic variability in speech. Specifically, we examine whether IFS are best represented as outputs to neural networks or as inputs by building models that embody both choices and examining their capacity to account for uncertainty effects in the formant trajectories of word final [ɐ], which in German discriminates around sixty different IFS. Overall, we find that formants are enhanced as the uncertainty associated with IFS decreases. This result dovetails with a growing number of studies of morphological and inflectional families that have shown that enhancement is associated with lower uncertainty in context. Importantly, we also find that in models where IFS serve as inputs—as our theoretical analysis suggests they ought to—its uncertainty measures provide better fits to the empirical variance observed in [ɐ] formants than models where IFS serve as outputs. This supports our suggestion that IFS serve as cognitive cues during speech production, and should be treated as such in modeling. It is also consistent with the idea that when IFS serve as inputs to a learning network. This maintains the distinction between those parts of the network that represent message and those that represent signal. We conclude by describing how maintaining a “signal-message-uncertainty distinction” can allow us to reconcile a range of apparently contradictory findings about the relationship between articulation and uncertainty in context.

Mitos ve Logos kavramları Antik Yunan uygarlığında söz kavramına karşılık gelen sözcükleri karşılamak için kullanılmıştır. Felsefe tarihinin başlangıcı için yapılan tanımlamalarda ise mitos kavramının yerine logos kavramının tercih edilmesi iki kavram arasında bir farklılığı ortaya koymak için yapılmaktadır. Bu ayrımın nedeni ise mitos’un daha çok dinsel içerikle anılması logos’un ise içerisinde bir tür akılsallık barındırması şeklindeki yorumlarda kendini göstermektedir. Ancak söz konusu ayrımın ilk doğa filozofu/ilk felsefeci olarak nitelendirilen Thales için geçerli olup olmadığı geçmişte olduğu gibi günümüzde de halen tartışılmaktadır. (...) Felsefe tarihi yazımlarında ilk sıraya konan Thales’in anılan kavramları gerçekten farklı şekilde yorumlayıp yorumlamadığı bizce de tartışmaya açık bir husustur. Bu açıdan bakıldığında Thales, söz konusu kavramları iki farklı problemler alanı olarak mı görmüştür? Onun düşüncelerinde kendinden önceki mitolojik mirasın izleri bulunabilir mi? O, katışıksız bir rasyonel midir, yoksa henüz felsefenin yeni filizlendiği bir toplumda bir ara basamağı mı temsil etmektedir? Bu makalenin içerisinde tartışacağımız bu sorular, felsefe tarihinin başlangıcına ilişkin kavramsal arka planın ne olduğu hakkında bize katkı sağlayacaktır. (shrink)

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)

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.

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)

Ontology development methodologies emphasise knowledge gathering from domain experts and documentary resources, and knowledge representation using an ontology language such as OWL or FOL. However, working ontologists are often surprised by how challenging and slow it can be to develop ontologies. Here, with a particular emphasis on the sorts of ontologies that are content-heavy and intended to be shared across a community of users (reference ontologies), we propose that a significant and heretofore under-emphasised contributor of challenges during ontology development is (...) the need to create, or bring about, consensus in the face of disagreement. For this reason reference ontology development cannot be automated, at least within the limitations of existing AI approaches. Further, for the same reason ontologists are required to have specific social-negotiating skills which are currently lacking in most technical curricula. (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)

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)

Agricultural intensification and landscape homogenisation are major drivers of biodiversity loss in European agricultural landscapes. Improvements require changes in farming practices, but empirical evidence on farmers’ motivations underlying their on-farm biodiversity management remains fragmented. To date, there is no aggregated overview of behavioural determinants that influence European farmers’ decisions to implement biodiversity-friendly farming practices. This study aims to fill this knowledge gap by conducting a systematic literature review of 150 empirical studies published between 2000 and 2022. We identified 108 potential (...) determinants of farmers’ behaviour, which were integrated into a multilevel framework. The results show that the farmers’ decisions are complex and often non-directional processes, shaped by numerous external (at a society, landscape, community, and farm level) and internal factors. These factors are embedded in regional and cultural contexts. However, the analysis of study sites indicates that the spatial coverage of scientific evidence on biodiversity-friendly farming measures is uneven across Europe. Given the diversity of local and socio-cultural conditions, there is a need for public policies, including the European Union’s Common Agricultural Policy, to address more specifically determinants encouraging biodiversity-friendly farm management. This entails reflecting culture-specific perspectives and incorporating experiential knowledge into multilevel policy design processes, as well as offering regionally adapted advice on measure implementation and biodiversity impacts.

The hitherto neglected Pandechion epistemonicon, Ulisse Aldrovandi’s extant manuscript encyclopaedia, indicates that Renaissance naturalists did not necessarily apply the humanist jack-of-all-trades, the commonplace book, in their own field without considerably altering its form. Over many years the Italian natural historian tested and recombined different techniques to arrive at the form of paper technology that he considered to be the most fit for his purposes. Not all of these techniques were taught at school or university.

This thesis aims to clarify a number of conceptual aspects of the debate surrounding algorithmic fairness. The particular focus here is the role of causal modeling in defining criteria of algorithmic fairness. In Chapter 1, I argue that in the discussion of algorithmic fairness, two fundamentally distinct notions of fairness have been conflated. Subsequently, I propose that what is usually taken to be the problem of algorithmic fairness should be divided into two subproblems, the problem of predictive fairness, and the (...) problem of allocative fairness. At the core of Chapter 2 is the proof of a theorem that establishes that three of the most popular (predictive) fairness criteria are pairwise incompatible. In particular, I show that under certain conditions, a predictive algorithm that satisfies a criterion called counterfactual fairness will with logical necessity violate two other popular predictive fairness criteria called equalized odds and predictive parity. In Chapter 3, a new predictive fairness criterion is developed using a mathematical framework for causal modeling. This fairness criterion, which I call causal relevance fairness, is a relaxation of another popular fairness criterion, counterfactual fairness, but turns out to be more closely in line with philosophical theories of discrimination. In Chapter 4, another infamous impossibility result in algorithmic fairness is analyzed through the lens of causality. I argue that by using a causal inference method called matching, we can modify the two fairness criteria equalized odds and predictive parity in a way that resolves the impossibility. Lastly, Chapter 5 contains an empirical case study. In it, the fairness of a popular recidivism risk prediction tool is analyzed using the criteria of (predictive) fairness developed earlier.

I discuss a contemporary solution to the dynamic problem of old evidence (POE), as proposed by Sprenger. Sprenger’s solution combines the Garber–Jeffrey–Niiniluoto (GJN) approach with Howson’s suggestion of counterfactually removing the old evidence from scientists’ belief systems. I argue that in the dynamic POE, the challenge is to explain how an insight under beliefs in which the old evidence E is known increased the credence of a scientific hypothesis. Therefore, Sprenger’s counterfactual solution, in which E has been artificially removed, does (...) not resolve the problem. I consider several potential responses. (shrink)

This paper critically examines the metaphorical use of medical terms in philosophy. Three examples selected from distinct philosophical contexts demonstrate that such terms have been employed as metaphors both to describe the practice of philosophising and historically to diagnose philosophical positions. The selected examples are (i) the title of Avicenna’s main philosophical work, The Book of Healing, (ii) the criticism of medical metaphors in Enlightenment philosophy, and (iii) recent historical diagnoses in philosophy. The underlying epistemological assumptions of all three contexts (...) are reconstructed to critically analyse the medical metaphors. Through this tripartite synopsis, I arrive at a normative conclusions medical metaphors, such as the “healing of the soul” or “pathology of reason”, do not stand up to the critique of Enlightenment and are obsolete against the theoretical background of my reference texts.
