From the early reception of Thomas Aquinas up to the present, many have interpreted his theory of liberum arbitrium to imply intellectual determinism: we do not control our choices, because we do not control the practical judgments that cause our choices. In this paper we argue instead that he rejects determinism in general and intellectual determinism in particular, which would effectively destroy liberum arbitrium as he conceives of it. We clarify that for Aquinas moral responsibility presupposes liberum arbitrium and thus (...) the ability to do otherwise, although the ability to do otherwise applies differently to praise and blame. His argument against intellectual determinism is not straightforward, but we construct it by analogy to his arguments against other deterministic threats. The non-determinism of the intellect’s causality with respect to the will results from his claims that practical reasoning is defeasible and that the reasons for actions are not contrastive reasons.

The contribution of the body to cognition and control in natural and artificial agents is increasingly described as “off-loading computation from the brain to the body”, where the body is said to perform “morphological computation”. Our investigation of four characteristic cases of morphological computation in animals and robots shows that the ‘off-loading’ perspective is misleading. Actually, the contribution of body morphology to cognition and control is rarely computational, in any useful sense of the word. We thus distinguish (1) morphology that (...) facilitates control, (2) morphology that facilitates perception and the rare cases of (3) morphological computation proper, such as ‘reservoir computing.’ where the body is actually used for computation. This result contributes to the understanding of the relation between embodiment and computation: The question for robot design and cognitive science is not whether computation is offloaded to the body, but to what extent the body facilitates cognition and control – how it contributes to the overall ‘orchestration’ of intelligent behaviour.

Climate change and decarbonization raise complex justice questions that researchers and policymakers must address. The distributions of greenhouse gas emissions rights and mitigation efforts have dominated justice discourses within scenario research, an integrative element of the IPCC. However, the space of justice considerations is much larger. At present, there is no consistent approach to comprehensively incorporate and examine justice considerations. Here we propose a conceptual framework grounded in philosophical theory for this purpose. We apply this framework to climate mitigation scenarios (...) literature as proof of concept, enabling a more holistic and multidimensional investigation of justice. We identify areas of future research, including new metrics of service provisioning essential for human well-being. [Can be freely read by clicking the ReadCube link below.]. (shrink)

An action-oriented perspective changes the role of an individual from a passive observer to an actively engaged agent interacting in a closed loop with the world as well as with others. Cognition exists to serve action within a landscape that contains both. This chapter surveys this landscape and addresses the status of the pragmatic turn. Its potential influence on science and the study of cognition are considered (including perception, social cognition, social interaction, sensorimotor entrainment, and language acquisition) and its impact (...) on how neuroscience is studied is also investigated (with the notion that brains do not passively build models, but instead support the guidance of action). A review of its implications in robotics and engineering includes a discussion of the application of enactive control principles to couple action and perception in robotics as well as the conceptualization of system design in a more holistic, less modular manner. Practical applications that can impact the human condition are reviewed (e.g., educational applications, treatment possibilities for developmental and psychopathological disorders, the development of neural prostheses). All of this foreshadows the potential societal implications of the pragmatic turn. The chapter concludes that an action-oriented approach emphasizes a continuum of interaction between technical aspects of cognitive systems and robotics, biology, psychology, the social sciences, and the humanities, where the individual is part of a grounded cultural system.

The philosophy of modality investigates necessity and possibility, and related notions--are they objective features of mind-independent reality? If so, are they irreducible, or can modal facts be explained in other terms? This volume presents new work on modality by established leaders in the field and by up-and-coming philosophers. Between them, the papers address fundamental questions concerning realism and anti-realism about modality, the nature and basis of facts about what is possible and what is necessary, the nature of modal knowledge, modal (...) logic and its relations to necessary existence and to counterfactual reasoning. The general introduction locates the individual contributions in the wider context of the contemporary discussion of the metaphysics and epistemology of modality. (shrink)

Over the last two decades, the capabilities approach has become an increasingly influential theory of development. It conceptualises human wellbeing in terms of an individual's ability to achieve functionings we have reason to value. In contrast, the African ethic of ubuntu views human flourishing as the propensity to pursue relations of fellowship with others, such that relationships have fundamental value. These two theoretical perspectives seem to be in tension with each other; while the capabilities approach focuses on individuals as the (...) locus of ethical value, an ubuntu ethic concentrates on the relations between individuals. In this article, we ask: to what extent is the capabilities approach compatible with this African ethical theory? We argue that, on reflection, relations play a much stronger role in the capabilities approach than often assumed. There is good reason to believe that relationality is part of the concept of a capability itself, where such relationality has intrinsic ethical value. This understanding of the ethical centrality of relations grounds new normative perspectives on the capabilities approach, and offers a more comprehensive grasp of the relevance of relationships to empirical enquiry.

Recent advancements in AI have prompted a large number of AI ethics guidelines published by governments and nonprofits. While many of these papers propose concrete or seemingly applicable ideas, few philosophically sound proposals are made. In particular, we observe that the line of questioning has often not been examined critically and underlying conceptual problems not always dealt with at the root. In this paper, we investigate the nature of ethical AI systems and what their moral status might be by first (...) turning to the notions of moral agency and patience. We find that their explication would come at a too high cost which is why we, second, articulate a different approach that avoids vague and ambiguous concepts or the problem of other minds. Third, we explore the impact of our philosophical and conceptual analysis on the regulatory landscape, make this link explicit, and finally propose a set of promising policy steps. (shrink)

Abductive reasoning takes place in forming``hypotheses'''' in order to explain ``facts.'''' Thus, theconcept of abduction promises an understanding ofcreativity in science and learning. It raises,however, also a lot of problems. Some of them will bediscussed in this paper. After analyzing thedifference between induction and abduction (1), Ishall discuss Peirce''s claim that there is a ``logic''''of abduction (2). The thesis is that this claim can beunderstood, if we make a clear distinction between inferential elements and perceptive elements of abductive reasoning. For (...) Peirce, the creative act offorming explanatory hypotheses and the emergence of``new ideas'''' belongs exclusively to the perceptive side of abduction. Thus, it is necessary to study the roleof perception in abductive reasoning (3). A furtherproblem is the question whether there is arelationship between abduction and Peirce''s concept of``theorematic reasoning'''' in mathematics (4). Both forms of reasoning could be connected, because both arebased on perception. The last problem concerns therole of instincts in explaining the success ofabductive reasoning in science, and the question whether the concept of instinct might be replaced bymethods of inquiry (5).

Previous research has shown that subliminally presented stimuli accelerate or delay responses afforded by supraliminally presented stimuli. Our experiments extend these findings by showing that unconscious stimuli even affect free choices between responses. Thus, actions that are phenomenally experienced as freely chosen are influenced without the actor becoming aware of the manipulation. However, the unconscious influence is limited to a response bias, as participants chose the primed response only in up to 60% of the trials. LRP data in free choice (...) trials indicate that the prime was not ineffective in trials in which participants chose the non-primed response as then it delayed performance of the incongruently primed response.

Based on a qualitative survey among 203 US workers active on the microwork platform Amazon Mechanical Turk, we analyze potential biases embedded in the institutional setting provided by on-demand crowdworking platforms and their effect on perceived workplace fairness. We explore the triadic relationship between employers, workers, and platform providers, focusing on the power of platform providers to design settings and processes that affect workers’ fairness perceptions. Our focus is on workers’ awareness of the new institutional setting, frames applied to the (...) mediating platform, and a differentiated analysis of distinct fairness dimensions. (shrink)

In this article, the authors explore the impact of a potential future regulatory decision by FDA whether or not to continue its enforcement discretion policy allowing physicians to perform, and stool banks to sell, stool product for fecal microbiota transplantation as a treatment for recurrent Clostridium Difficile infection without an Investigative New Drug application. The paper looks at the Agency's regulatory options in light of the current gut microbiota based products that are in the FDA pipeline for drug approval and (...) the potential impact and repercussions of their approval on FDA action. In laying out FDA's options we consider the implications of market exclusivity and off-label use of newly approved drugs. Ultimately, we explore the potential impact of FDA's decision on patients, research, and innovation. (shrink)

100 years ago, the editors of the Journal of Educational Psychology conducted one of the most famous studies of experts' conceptions of human intelligence. Reason enough to prompt the question where we stand today with conceptualizing 'intelligence'. In this paper, I provide a synopsis of the latest research on human intelligence(s). I embrace the notion of intelligence as a non-unitary faculty with pluralistic forms. Even though I do not provide a definition of 'intelligence' of my own, I provide good reasons (...) for this reluctance. Nonetheless, I specify the term as complex, gradual, embedded, multidirectional, and dynamic. Furthermore, I argue for the special status of musical, not linguistic, intelligence. (shrink)

In this book Tobias Hoffmann studies the medieval free will debate during its liveliest period, from the 1220s to the 1320s, and clarifies its background in Aristotle, Augustine, and earlier medieval thinkers. Among the wide range of authors he examines are not only well-known thinkers such as Thomas Aquinas, Duns Scotus, and William of Ockham, but also a number of authors who were just as important in their time and deserve to be rediscovered today. To shed further light on their (...) theories of free will, Hoffmann also explores their competing philosophical explanations of the fall of the angels, that is, the hypothesis of an evil choice made by rational beings under optimal psychological conditions. As he shows, this test case imposed limits on tracing free choices to cognition. His book provides a comprehensive account of a debate that was central to medieval philosophy and continues to occupy philosophers today. (shrink)

We study model theory of actions of finite groups on substructures of a stable structure. We give an abstract description of existentially closed actions as above in terms of invariants and PAC structures. We show that if the corresponding PAC property is first order, then the theory of such actions has a model companion. Then, we analyze some particular theories of interest (mostly various theories of fields of positive characteristic) and show that in all the cases considered the PAC property (...) is first order.

Chemical structures are among the trademarks of our profession, as surely chemical as flasks, beakers and distillation columns. When someone sees one of us busily scribbling formulas or structures, he or she has no trouble identifying a chemist.

They raise interesting and difficult questions about representation. It is the intent (...) of this article to reflect upon molecular graphics. (shrink)

Had more philosophers of science come from chemistry, their thinking would have been different. I begin by looking at a typical chemical paper, in which making something is the leitmotif, and conjecture/refutation is pretty much irrelevant. What in fact might have been, might be, different? The realism of chemists is reinforced by their remarkable ability to transform matter; they buy into reductionism where it serves them, but make no real use of it. Incommensurability is taken without a blink, and actually (...) serves. The preeminence of synthesis in chemistry could have led philosophers of science to take more seriously questions of aesthetics within science, and to find a place in aesthetics for utility. The necessary motion twixt macroscopic and microscopic views of matter in modern chemistry leads to the coexistence of symbolic and iconic representations. And in another way to the deliberate, creative violation of categories. (shrink)

We generalize a well-known theorem binding the elementary equivalence relation on the level of PAC fields and the isomorphism type of their absolute Galois groups. Our results concern two cases: saturated PAC structures and nonsaturated PAC structures.

Why do we formulate arguments? Usually, things such as persuading opponents, finding consensus, and justifying knowledge are listed as functions of arguments. But arguments can also be used to stimulate reflection on one’s own reasoning. Since this cognitive function of arguments should be important to improve the quality of people’s arguments and reasoning, for learning processes, for coping with “wicked problems,” and for the resolution of conflicts, it deserves to be studied in its own right. This contribution develops first steps (...) towards a theory of reflective argumentation. It provides a definition of reflective argumentation, justifies its importance, delineates it from other cognitive functions of argumentation in a new classification of argument functions, and it discusses how reflection on one’s own reasoning can be stimulated by arguments.

A significant amount of discussion in the bioethics community has been devoted to the question of whether individuals performing ethics consultations in healthcare institutions have any special expertise. In addition, articles in the lay press have questioned the “added value” that bioethicists bring to ethical dilemmas.

This research replicates Bhattacharjee et al. :1167–1184, 2013) moral decoupling model and extends the original along the dimensions of theory, method, and context. Adopting a branding perspective and focusing on the corporate domain rather than the public figures investigated by Bhattacharjee and colleagues, this research examines the proposition that consumers dissociate judgments of morality from judgments of performance to justify purchasing from companies deemed to act immorally. The original study is further extended by applying the model in a different cultural (...) context and employing a more realistic stimulus to establish external and ecological validity. The results of the replication generally support the original findings, in particular, under conditions of higher product involvement, a theoretical extension. (shrink)

We study algebraic and model-theoretic properties of existentially closed fields with an action of a fixed finite group. Such fields turn out to be pseudo-algebraically closed in a rather strong sense. We place this work in a more general context of the model theory of fields with a group scheme action.

Medieval authors generally agreed that we have the freedom to choose among alternative possibilities. But most medieval authors also thought that there are situations in which one cannot do otherwise, not even will otherwise. They also thought when willing necessarily, the will remains free.

As a committee of the National Academy of Engineering recognized, ethics education should foster the ability of students to analyze complex decision situations and ill-structured problems. Building on the NAE’s insights, we report about an innovative teaching approach that has two main features: first, it places the emphasis on deliberation and on self-directed, problem-based learning in small groups of students; and second, it focuses on understanding ill-structured problems. The first innovation is motivated by an abundance of scholarly research that supports (...) the value of deliberative learning practices. The second results from a critique of the traditional case-study approach in engineering ethics. A key problem with standard cases is that they are usually described in such a fashion that renders the ethical problem as being too obvious and simplistic. The practitioner, by contrast, may face problems that are ill-structured. In the collaborative learning environment described here, groups of students use interactive and web-based argument visualization software called “AGORA-net: Participate – Deliberate!”. The function of the software is to structure communication and problem solving in small groups. Students are confronted with the task of identifying possible stakeholder positions and reconstructing their legitimacy by constructing justifications for these positions in the form of graphically represented argument maps. The argument maps are then presented in class so that these stakeholder positions and their respective justifications become visible and can be brought into a reasoned dialogue. Argument mapping provides an opportunity for students to collaborate in teams and to develop critical thinking and argumentation skills. (shrink)

Recent findings about the capabilities of smart animals such as corvids or octopi and novel types of artificial intelligence, from social robots to cognitive assistants, are provoking the demand for new answers for meaningful comparison with other kinds of intelligence.

Second, we provide a method for coding absolute Galois groups of structures, so they can be interpreted in some monster model with an additional predicate.

Fourth, we describe Kim-dividing in (...) these PAC substructures and show several results related to the SOPnhierarchy. Fifth, we characterize the algebraic closure in PAC structures. (shrink)

Moral licensing theory posits that individuals who initially behave morally may later display behaviors that are immoral, unethical, or otherwise problematic. While previous literature mainly focused on individual moral licensing, the influences from the social environment have barely been investigated. To address this issue, the present paper develops a conceptual framework of social moral licensing and outlines two main avenues for future research via six propositions. The first avenue entitled “the conspicuousness of moral licensing” considers moral licensing that comes into (...) play when people are observed by others. The second avenue entitled “the relativity of moral licensing” focusses on social comparisons between individuals, their ingroups and outgroups. Specific and testable social moral licensing effects are derived in both avenues. By doing so, this paper outlines promising directions for future studies in this new research stream. (shrink)

This essay is the first attempt to compare Reinhart Koselleck's Historik with Hannah Arendt's political anthropology and her critique of the modern concept of history. Koselleck is well-known for his work on conceptual history as well as for his theory of historical time. It is my contention that these different projects are bound together by Koselleck's Historik, that is, his theory of possible histories. This can be shown through an examination of his writings from Critique and Crisis to his final (...) essays on historical anthropology, most of which have not yet been translated into English. Conversely, Arendt's political theory has in recent years been the subject of numerous interpretations that do not take into account her views about history. By comparing the anthropological categories found in Koselleck's Historik with Arendt's political anthropology, I identify similar intellectual lineages in them as well as shared political sentiments, in particular the anti-totalitarian impulse of the postwar era. More importantly, Koselleck's theory of the preconditions of possible histories and Arendt's theory of the preconditions of the political, I argue, transcend these lineages and sentiments by providing essential categories for the analysis of historical experience.

Among the many problems posed by Peirce's concept of abduction is how to determine the scope of this form of inference, and how to distinguish different types of abduction. This problem can be illustrated by taking a look at one of his best known definitions of the term:Abduction is the process of forming an explanatory hypothesis. It is the only logical operation which introduces any new idea; for induction does nothing but determine a value, and deduction merely evolves the necessary (...) consequences of a pure hypothesis.The second half of this quote is not part of the definition, but an explanation of it.

Discussions concerning belief revision, theorydevelopment, and ``creativity'' in philosophy andAI, reveal a growing interest in Peirce'sconcept of abduction. Peirce introducedabduction in an attempt to providetheoretical dignity and clarification to thedifficult problem of knowledge generation. Hewrote that ``An Abduction is Originary inrespect to being the only kind of argumentwhich starts a new idea'' (Peirce, CP 2.26).These discussions, however, led to considerabledebates about the precise way in which Peirce'sabduction can be used to explain knowledgegeneration (cf. Magnani, 1999; Hoffmann, 1999).The crucial question is (...) that of understandinghow we can get the new elements capableof enlarging our theories. Under thesecircumstances, it might be helpful to step outof the entanglement and reconsider the basis ofthe problem that originally triggered Peirce'sinterest in abduction. This will lead us toanother Peircean concept, that of ``diagrammaticreasoning,'' which I discuss here in the contextof his ``pragmatism.'' In this way, I hope toreach a better understanding of thecontribution of ``abduction'' to the knowledgegeneration process. (shrink)

Over recent years, the research community has been increasingly using preprint servers to share manuscripts that are not yet peer-reviewed. Even if it enables quick dissemination of research findings, this practice raises several challenges in publication ethics and integrity. In particular, preprints have become an important source of information for stakeholders interested in COVID19 research developments, including traditional media, social media, and policy makers. Despite caveats about their nature, many users can still confuse pre-prints with peer-reviewed manuscripts. If unconfirmed but (...) already widely shared first-draft results later prove wrong or misinterpreted, it can be very difficult to “unlearn” what we thought was true. Complexity further increases if unconfirmed findings have been used to inform guidelines. To help achieve a balance between early access to research findings and its negative consequences, we formulated five recommendations: (a) consensus should be sought on a term clearer than ‘pre-print’, such as ‘Unrefereed manuscript’, “Manuscript awaiting peer review” or ‘’Non-reviewed manuscript”; (b) Caveats about unrefereed manuscripts should be prominent on their first page, and each page should include a red watermark stating ‘Caution—Not Peer Reviewed’; (c) pre-print authors should certify that their manuscript will be submitted to a peer-review journal, and should regularly update the manuscript status; (d) high level consultations should be convened, to formulate clear principles and policies for the publication and dissemination of non-peer reviewed research results; (e) in the longer term, an international initiative to certify servers that comply with good practices could be envisaged.

G protein‐coupled receptors (GPCRs) constitute the largest family of transmembrane proteins and play a crucial role in regulating diverse cellular functions. They transmit their signaling via binding to intracellular signal transducers and effectors, such as G proteins, GPCR kinases, and β‐arrestins. To influence specific GPCR signaling behaviors, β‐arrestins recruit effectors to form larger signaling complexes. Intriguingly, they facilitate divergent functions for the binding to different receptors. Recent studies relying on advanced structural approaches, novel biosensors and interactome analyses bring us closer (...) to understanding how this specificity is achieved. In this article, we share our hypothesis of how active GPCRs induce specific conformational rearrangements within β‐arrestins to reveal distinct binding interfaces, enabling the recruitment of a subset of effectors to foster specialized signaling complexes. Furthermore, we discuss methods of how to comprehensively assess β‐arrestin conformational states and present the current state of research regarding the functionality of these multifaceted scaffolding proteins.

Many consumers implicitly associate sustainability with lower product strength. This so-called ethical = less strong intuition (ELSI) poses a major threat for the success of sustainable products. This article explores this pervasive lay theory and examines whether it is a key barrier for sustainable consumption patterns. Even more importantly, little is known about the underlying mechanisms that might operate differently at the implicit and explicit levels of the consumer’s decision-making. To fill this gap, three studies examine how the implicit judgments (...) that consumers activate automatically shape their consumption behaviors, in concert with their more controlled explicit beliefs about sustainable products. The Main Study investigates the ELSI’s imprint on actual shopping patterns and disentangles the implicit and explicit mechanisms of the lay theory. This paper also asks how this negative influence can be attenuated by examining whether the consumer’s interest in sustainable consumption reduces reliance on the ELSI. Two follow-up studies confirm the robustness from different methodological and practical perspectives. Implications for companies and policy makers are derived. (shrink)

Historically, biocentrists have ascribed interests to organisms via an account of function. One promising account of function for this purpose is the organizational or autopoietic account of function, according to which some entity x has a function of self-maintenance when the parts of x contribute to the goal of self-maintenance. In this paper, I will present the autopoietic account of interests and provide some reasons for thinking that this account is promising. I will also present a possible issue for the (...) biocentrist who uses the autopoietic account of function given the following two claims: what it means to be a biological “self” is ambiguous, and the autopoietic account of interests relies on a self boundary. I argue that the proponent of this account then needs to choose a definition of individual and explain why that definition is morally relevant. Otherwise, the proponent of the autopoietic account has not given an account of what constitutes a harm or a benefit for a biological individual, and there are good reasons to believe that this is a necessary component of any account of interests.

We study model theory of fields with actions of a fixed finite group scheme. We prove the existence and simplicity of a model companion of the theory of such actions, which generalizes our previous results about truncated iterative Hasse–Schmidt derivations [13] and about Galois actions [14]. As an application of our methods, we obtain a new model complete theory of actions of a finite group on fields of finite imperfection degree.
