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. The scholarship is immaculate, the writing crystal clear and the argumentation always powerful.' (Malcolm Budd). (shrink)

Ethics is normative; ethics indicates, in broad terms, what researchers should do. For example, researchers should respect human participants. Empirical study tells us what actually happens. Empirical research is often needed to fine-tune the best ways to achieve normative objectives, for example, to discover how best to achieve the dual aims of gaining important knowledge and respecting participants. Ethical decision making by scientists and institutional review boards should not be based on hunches and anecdotes (e.g., about such matters as what (...) information potential research participants would want to know and what they understand, or what they consider to be acceptable risks). These questions should be answered through empirical research. Some of the preceding articles in this special issue illustrate uses of empirical research on research ethics. This article places empirical research on research ethics into broader perspective and challenges investigators to use the tools of their disciplines to proactively solve ethical problems for which there currently exist no empirically proven solutions.

Modern neurotechnologies are rapidly infringing on conventional notions of human dignity and they are challenging what it means to be human. This article is a survey analysis of the future of the digital age, reflecting primarily on the effects of neurotechnology that violate universal human rights to dignity, self-determination, and privacy. In particular, this article focuses on neuromarketing to critically assess potentially negative social ramifications of under-regulated neurotechnological application. Possible solutions are critically evaluated, including the human rights claim to the (...) ‘right to mental privacy’ and the suggestion of a new human right based on spiritual jurisdiction, where the human psyche is a legal space in a substantive legal setting.

Society has reached a new rupture in the digital age. Traditional technologies of biopower designed around coercion no longer dominate. Psychopower has manifested, and its implementation has changed the way one understands biopolitics. This discussion note references Byung-Chul Han’s interpretation of modern psychopolitics to investigate whether basic human rights violations are committed by Facebook, Inc.’s product against its users at a psychopolitical level. This analysis finds that Facebook use can lead to international human rights violations, specifically cultural rights, social rights, (...) rights to self-determination, political rights, and the right to health.

Background Thorough information of the patient is an integral part of the process of shared decision making. We aimed to investigate if detailed information about medication may induce nocebo effects. Methods We conducted a randomized, single-blind, pilot-study including n = 51 psychiatric in-patients aged between 18 and 80 years with a depressive disorder and accompanying sleeping disorders. In the intervention group we provided thorough information about adverse effects, while the control group received only a simple consent procedure. In both groups, (...) patients received an open-label placebo pill instead of their sleeping medication. Results No statistically significant differences between the intervention group and the control group were found regarding the main outcome parameter. Conclusion In this study, we were not able detect an effect of informed consent vs. simple consent on the emergence of placebo or nocebo effects. This finding is contrary to most assumptions and publications about this topic. Trial registration Trial registration number: DRKS00017653, registered August 30th 2018. Retrosprectively registered.

As part of the social distancing measures for preventing the spread of COVID-19, many university courses were moved online. There is an assumption that online teaching limits opportunities for fostering interpersonal relationships and students’ satisfaction of the basic need for relatedness – reflected by experiencing meaningful interpersonal connections and belonging – which are considered important prerequisites for student motivation and vitality. In educational settings, an important factor affecting students’ relatedness satisfaction is the teachers’ behavior. Although research suggests that relatedness satisfaction (...) may be impaired in online education settings, to date no study has assessed how university lecturers’ relatedness support might be associated with student relatedness satisfaction and therefore, student motivation and vitality. This study tested this mediating relationship using data collected during the early days of the COVID-19 pandemic. The study also investigated whether the relations were moderated by a high affiliation motive which reflects a dispositional wish for positive and warm relationships. The possible importance of the communication channel selected by the lecturers and the format of a class were also investigated. In a sample of N = 337 students, we tested our hypotheses using structural equation model. Results confirmed mediation, but not moderation. The use of video chat seems to facilitate the provision of relatedness support but our data did not show that the format of a class was associated with relatedness. Our findings indicate that both teaching behavior and the technical format used to deliver lectures play important roles in student experiences with online classes. The results are discussed in light of other research conducted during the pandemic. (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.

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.

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)

Sich dem Phänomen des Computerspielens aus der Perspektive der philosophischen Handlungstheorie zu nähern, kann einem zunächst nicht besonders vielversprechend vorkommen. Und dies aus zwei Gründen: Zum einen scheint sich der universalistische Anspruch der Handlungstheorie nicht besonders gut mit dem Studium eines Partikularbereichs menschlichen Tuns zu vertragen. Denn die Handlungstheorie ist jener Bereich der Philosophie, der zu erklären versucht, wie man das Phänomen des menschlichen Handelns als solches verstehen kann. Das heißt in der Philosophie des Handelns wird der Frage nachgegangen, auf (...) welche Weise wir am besten verstehen können, dass Handlungen sich von anders gearteten Bewegungen unseres Körpers einerseits aber auch von der Art des zielgerichteten Verhaltens, zu dem Tiere in der Lage sind, unterscheiden. Handlungstheorie, so kann man das auch beschreiben, ist eine Form der Anthropologie: Sie beschreibt eine spezielle Weise, in der sich unsere Charakteristik als vernünftiges Tier ausbuchstabieren lässt.

Philip Pettit’s republican conception of freedom is presented as an alternative both to negative and positive conceptions of freedom. The basic idea is to conceptualize freedom as non-domination, not as non-interference or self-mastery. When compared to negative freedom, Pettit’s republican conception comprises two controversial claims: the claim that we are unfree if we are dominated without actual interference, and the claim that we are free if we face interference without domination. Because the slave is a widely accepted paradigm of the (...) unfree person, the case of a slave with a non-interfering master is often cited as providing a good argument for the first republican claim and against a negative conception of freedom. One aim of this article is to raise doubts about whether this is true. The other aim of the article is to show that the prisoner—also a paradigm of the unfree person—presents a good argument against the second republican claim and in favour of a negative conception of freedom. This is called the ‘prisoner-argument’. It will be argued that neither Pettit’s distinction between free persons and free choices nor his distinction between compromising and conditioning factors of freedom can help to rebut the charge of the prisoner-argument.

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)

In many critical investigations of machine vision, the focus lies almost exclusively on dataset bias and on fixing datasets by introducing more and more diverse sets of images. We propose that machine vision systems are inherently biased not only because they rely on biased datasets but also because theirperceptual topology, their specific way of representing the visual world, gives rise to a new class of bias that we callperceptual bias. Concretely, we define perceptual topology as the set of those inductive (...) biases in machine vision systems that determine its capability to represent the visual world. Perceptual bias, then, describes the difference between the assumed “ways of seeing” of a machine vision system, our reasonable expectations regarding its way of representing the visual world, and its actual perceptual topology. We show how perceptual bias affects the interpretability of machine vision systems in particular, by means of a close reading of a visualization technique called “feature visualization”. We conclude that dataset bias and perceptual bias both need to be considered in the critical analysis of machine vision systems and propose to understand critical machine vision as an important transdisciplinary challenge, situated at the interface of computer science and visual studies/Bildwissenschaft.

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)

This Chapter presents an analysis of the idea of social pathology and its role in Frankfurt School Critical Theory. I suggest that this idea can set Critical Theory apart from mainstream liberal approaches, but also note the challenges involved in doing so, urging a return to its original, interdisciplinary program.

Although the individuality of whole-body movements has been suspected for years, the scientific proof and systematic investigation that individuals possess unique movement patterns did not manifest until the introduction of the criteria of uniqueness and persistence from the field of forensic science. Applying the criteria of uniqueness and persistence to the individuality of motor learning processes requires complex strategies due to the problem of persistence in the learning processes. One approach is to examine the learning process of different movements. For (...) this purpose, it is necessary to differentiate between two components of movement patterns: the individual-specific component and the discipline-specific component. To this end, a kinematic analysis of the shot put, discus, and javelin throwing movements of seven high-performance decathletes during a qualification competition was conducted. In total, joint angle waveforms of 57 throws formed the basis for the recognition task of individual- and discipline-specific throwing patterns using a support vector machine. The results reveal that the kinematic throwing patterns of the three disciplines could be distinguished across athletes with a prediction accuracy of up to 100% (57 of 57 throws). However, athlete-specific throwing characteristics could also be identified across the three disciplines. Prediction accuracies of up to 52.6% indicated that up to 10 out of 19 throws of a discipline could be assigned to the correct athletes, based on only knowing these athletes from the kinematic throwing patterns in the other two disciplines. The results further suggest that individual throwing characteristics across disciplines are more pronounced in shot put and discus throwing than in javelin throwing. Applications for training and learning practice in sports and therapy are discussed. In summary, the chosen approach offers a broad field of application related to the search of individually optimal movement solutions in sports. (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)

The article argues that persons should be conceived as self-owners and entitled to acquire private property within justifiable property conventions because they should be able to live as project pursuers. This is the ‘project pursuit argument’. It leads to a conception of self-ownership that is stringent, but weaker than standard libertarian notions of self-ownership, and to an understanding of private property as a convention that has to meet a sufficientarian threshold in order to be justifiable.

In this article, I defend the view that we can acquire factual knowledge – that is, contingent propositional knowledge about certain (perceivable) aspects of reality – on the basis of imaginative experience. More specifically, I argue that, under suitable circumstances, imaginative experiences can rationally determine the propositional content of knowledge-constituting beliefs – though not their attitude of belief – in roughly the same way as perceptual experiences do in the case of perceptual knowledge. I also highlight some philosophical consequences of (...) this conclusion, especially for the issue of whether imagination can help us to learn something from fictions. (shrink)

The article defends the claim that if some laws are (or would be) widely accepted, this provides pro tanto moral reasons to support these laws and not to support otherwise better laws that are not widely accepted. In that sense the value of having widely accepted laws provides moral reasons to make compromises in politics, and it justifies a modest and qualified status quo bias. Widely accepted laws are valuable because they reduce enforcement costs, have symbolic value, help to maintain (...) peace, and realize the value of non-subjugation. (shrink)

While John Rawls made the notion of a “modus vivendi” prominent in political philosophy, he treats modus vivendi arrangements rather short and dismissively. On the other hand, some political theorists like John Gray praise modus vivendi as the only available and legitimate goal of politics. In the article I sketch the outlines of a different, more nuanced approach to modus vivendi arrangements. I argue that the moral standing of modus vivendi arrangements varies, and I try to spell out the factors (...) that determine the relative moral standing of modus vivendi arrangements. (shrink)

This article investigates the categories of variegated social formations and structural historical heterogeneity, which have been developed from Latin American Marxism as a theoretical attempt that aims to account for the complexity of the debates around historical time. For this, the work of René Zavaleta Mercado (Bolivia) and Aníbal Quijano (Peru) is analyzed, revealing their connections and divergences. It is concluded that there are important meeting points, but also disagreements.

In line with Allen Newell's challenge to develop complete cognitive architectures, and motivated by a recent proposal for a unifying subsymbolic computational theory of cognition, we introduce the cognitive control architecture SEMLINCS. SEMLINCS models the development of an embodied cognitive agent that learns discrete production rule-like structures from its own, autonomously gathered, continuous sensorimotor experiences. Moreover, the agent uses the developing knowledge to plan and control environmental interactions in a versatile, goal-directed, and self-motivated manner. Thus, in contrast to several well-known (...) symbolic cognitive architectures, SEMLINCS is not provided with production rules and the involved symbols, but it learns them. In this paper, the actual implementation of SEMLINCS causes learning and self-motivated, autonomous behavioral control of the game figure Mario in a clone of the computer game Super Mario Bros. Our evaluations highlight the successful development of behavioral versatility as well as the learning of suitable production rules and the involved symbols from sensorimotor experiences. Moreover, knowledge- and motivation-dependent individualizations of the agents’ behavioral tendencies are shown. Finally, interaction sequences can be planned on the sensorimotor-grounded production rule level. Current limitations directly point toward the need for several further enhancements, which may be integrated into SEMLINCS in the near future. Overall, SEMLINCS may be viewed as an architecture that allows the functional and computational modeling of embodied cognitive development, whereby the current main focus lies on the development of production rules from sensorimotor experiences.

Constitutive Russellian panpsychism seems to combine the strengths of its rivals, physicalism and dualism, while avoiding their weaknesses: by acknowledging the irreducibility of phenomenal properties yet grounding macro- in microphenomenality, the view can avoid both anti-physicalist arguments and the causal exclusion problem for dualism. However, two severe objections have been raised: the combination problem for phenomenal constitution, and the structural exclusion problem for the position’s account of microphenomenal causation. It is currently hotly debated whether the combination problem can be overcome. (...) If not, panpsychists are forced to view macrophenomenality as emergent. Yet emergent panpsychism is subject to the causal exclusion problem, thereby sacrificing panpsychism’s advantage over dualism. With regard to the structural exclusion problem, Mørch provides a solution in terms of microphenomenal powers. I argue that Mørch’s view is not tenable. This notwithstanding, I develop a modification of her view which can solve the structural exclusion problem. Moreover, the emergentist version of this approach can avoid the causal exclusion problem. Thus, I aim to provide both a satisfying account of microphenomenal causation in panpsychism and a viable version of emergent panpsychism in case the combination problem turns out to be unsolvable.

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)

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.

En este artículo se discute la relación entre silogismo y demostración con respecto al concepto aristotélico del conocimiento científico formulado en los Analíticos segundos. La argumentación sigue tres líneas principales: (i) se ofrecen razones para rechazar la relegación de la sistematización silogística a la instancia postrera de justificación y exposición didáctica del conocimiento previamente adquirido. Como respuesta alternativa, (ii) se muestra que una explicación aristotélica necesita la silogística en virtud del papel que desempeña la causa como término medio silogístico. En (...) consecuencia, debería estar en condiciones de (iii) sostener que no resulta factible establecer firmemente los principios propios como premisas explicativas sin construir silogismos. This article focuses on the relation between syllogism and demonstration, as related to Aristotle's concept of scientific knowledge in his Posterior Analytics. Three main lines of argumentation are followed: (i) reasons are given to reject that syllogistic systematization plays a unique role as a skill for justification and didactic proof of a body of knowledge previously acquired. Alternatively, (ii) it is showed that an Aristotelian explanation requires syllogistic as to the role of cause as middle syllogistic term. Thus, it should be feasible (iii) to sustain that it is not possible to firmly establish proper principles as explanative premises without constructing syllogisms. (shrink)

Must we ascribe hope for better times to those who (take themselves to) act morally? Kant and later theorists in the Frankfurt School tradition thought we must. In this article, I disclose that it is possible – and ethical – to refrain from ascribing hope in all such cases. I draw on two key examples of acting irrespective of hope: one from a recent political context and one from the life of Jean Améry. I also suggest that, once we see (...) that it is possible to make sense of (what I call) ‘merely expressive acts’, we can also see that the early Frankfurt School wasnotguilty of a performative contradiction in seeking to enlighten Enlightenment about its (self-)destructive tendencies, while rejecting the (providential) idea of progress.

To learn whether criticism and regulation of research practices have been followed by a reduction of deception or use of more acceptable approaches to deception, the contents of all 1969, 1978, 1986, and 1992 issues of the Journal of Personality and Social Psychology were examined. Deception research was coded according to type of (non)informing (e.g., false informing, consent to deception, no informing), possible harmfulness of deception employed (e.g., powerfulness of induction, morality of the behavior induced, privacy of behavior), method of (...) deception (e.g., bogus device or role, false purpose of study, false feedback), and debriefing employed. Use of confederates has been partly replaced by uses of computers. "Consent" with false informing declined after 1969, then rose in 1992. Changes in the topics studied (e.g., attribution, socialization, personality) largely accounted for the decline in deception in 1978 and 1986. More attention needs to be given to ways of respecting subjects' autonomy, to appropriate debriefing and desensitizing, and to selecting the most valid and least objectionable deception methods.
