One of the more interesting philosophical debates today centers on the concept of potentiality. The Italian philosopher Giorgio Agamben has been one of the main driving forces behind the renewed interest in the concept, as he has made his own particular understanding of potentiality a crucial tool for his analyses in the book series on Homo Sacer.1 Agamben developed his understanding of potentiality through a striking reading of Aristotle that goes against the grain of certain generally accepted truths of Aristotelianism. (...) In particular, he claims that potentiality for Aristotle can be defined as "potentiality not to be", which seems to go against mainstream Aristotelian thought, according to... (shrink)

As biobank research has become increasingly widespread within biomedical research, study-specific consent to each study, a model derived from research involving traditional interventions on human subjects, has for the sake of feasibility gradually given way to alternative consent models which do not require consent for every new study. Besides broad consent these models include tiered, dynamic, and meta-consent. However, critics have pointed out that it is normally not known at the time of enrolment in what ways samples deposited in a (...) biobank may be used in future research and that, for a consent to be informed, exactly this kind of knowledge is required. Therefore, there is an ongoing debate about the ethical acceptability of going for less than study-specific consent. In light of this debate we address the question of how to best protect participants against relevant risks and violations of autonomy. We apply the central aims of the informed consent process to the unique circumstances of biobank research where samples and data in many cases are stored for long periods of time and reused in subsequent studies. Thereby we are able to formulate a set of criteria focusing both on the risk of informational harm and the potential violation of participants’ values. We compare existing models of consent based on their ability to satisfy the criteria, and we find that the broad consent model offers the best level of protection for participants, although, it suffers from a few important deficiencies with regards to protection against participant value violations and long-term protection of autonomy, if it is applied without qualifications. For this reason, we propose modifications to the current broad consent model, in order to ensure that it provides protection of autonomy and participant values through strong ethical review and continuous communication. We conclude that a modified form of broad consent is ethically superior in biobank research, not only because it is most feasible but primarily because it offers the best available protection against the hazards facing research subjects in this form of research.

The goal of the present paper is to construct a formal explication of the pluralistic ignorance explanation of the bystander effect. The social dynamics leading to inaction is presented, decomposed, and modeled using dynamic epistemic logic augmented with ‘transition rules’ able to characterize agent behavior. Three agent types are defined: First Responders who intervene given belief of accident; City Dwellers, capturing ‘apathetic urban residents’ and Hesitators, who observe others when in doubt, basing subsequent decision on social proof. It is shown (...) how groups of the latter may end in a state of pluralistic ignorance leading to inaction. Sequential models for each agent type are specified, and their results compared to empirical studies. It is concluded that only the Hesitator model produces reasonable results. (shrink)

Current debate and policy surrounding the use of genetic editing in humans often relies on a binary distinction between therapy and human enhancement. In this paper, we argue that this dichotomy fails to take into account perhaps the most significant potential uses of CRISPR-Cas9 gene editing in humans. We argue that genetic treatment of sporadic Alzheimer’s disease, breast- and ovarian-cancer causing BRCA1/2 mutations and the introduction of HIV resistance in humans should be considered within a new category of genetic protection (...) treatments. We find that if this category is not introduced, life-altering research might be unnecessarily limited by current or future policy. Otherwise ad hoc decisions might be made, which introduce a risk of unforeseen moral costs, and might overlook or fail to address some important opportunities. (shrink)

Seit fast 200 Jahren wird Clausewitz gelesen und interpretiert. Rasmus Beckmann erschließt seine Kriegstheorie den modernen Sozialwissenschaften. Dabei wird deutlich, dass sich Clausewitz keineswegs auf zwischenstaatliche Kriege beschränkt hat. Auch die asymmetrischen Kriege kann man durch seine Theorie besser analysieren und verstehen. Dies zeigt der Autor am Beispiel des Afghanistankrieges.

In this essay, I undertake a critical phenomenological exposition of the conditions of ethical community as they present themselves in the light of the Anthropocene. I begin by approaching the present human condition by following Arendt in her considerations of what more recently has been termed the Anthropocene. I will take her notion of the process character of action as a lodestar in a so-called anarcheological reading of Aristotle that opens for a thinking of unbounded possibility and unbounded affinity and (...) that shows how Aristotle’s ethics, like so many other ethical and moral theories, is really a project of metaphysical closure in the face of the poignantly sensed, but theoretically marginalized, anarchic apertures of communitary life. To prepare for an ethics capable of perpetually affirming, rather than closing off, these anarchic apertures of the human condition, I bring the insights won in the anarcheological reading of Aristotle into conversation with accounts of the ethical responses presented by the Native American nation of the Crow towards the end of the 19th century, when they – in a sense not-dissimilar to what we now experience in the Anthropocene – faced the end of the world. I conclude by extracting from this some elements for a thinking of ethics at the end of worlds that affirms the unbounded apertures of human community. (shrink)

Threshold models and their dynamics may be used to model the spread of ‘behaviors’ in social networks. Regarding such from a modal logical perspective, it is shown how standard update mechanisms may be emulated using action models – graphs encoding agents’ decision rules. A small class of action models capturing the possible sets of decision rules suitable for threshold models is identified, and shown to include models characterizing best-response dynamics of both coordination and anti-coordination games played on graphs. We conclude (...) with further aspects of the action model approach to threshold dynamics, including broader applicability and logical aspects. Hereby, new links between social network theory, game theory and dynamic ‘epistemic’ logic are drawn. (shrink)

Hintikka’s Knowledge and Belief from 1962 is considered the seminal treatise on epistemic logic. It provides the nuts and bolts of what is now a flourishing paradigm of significance to philosophy, economics, mathematics and theoretical computer science—in theory as well as practice. And in theory and for practice epistemic logic has been extensively articulated, refined and developed especially with respect to capturing the dynamics of reasoning about knowledge. But although the robust narrative about Hintikka’s epistemic logic is rather static, the (...) leap to dynamic epistemic logic is right there back in 1962 as this paper will show. (shrink)

There has been a recent interest in hierarchical generalizations of classic incompleteness results. This paper provides evidence that such generalizations are readily obtainable from suitably formulated hierarchical versions of the principles used in the original proofs. By collecting such principles, we prove hierarchical versions of Mostowski’s theorem on independent formulae, Kripke’s theorem on flexible formulae, Woodin’s theorem on the universal algorithm, and a few related results. As a corollary, we obtain the expected result that the formula expressing “$\mathrm {T}$is$\Sigma _n$-ill” (...) is a canonical example of a$\Sigma _{n+1}$formula that is$\Pi _{n+1}$-conservative over$\mathrm {T}$.

This article examines the prosody and sequential organisation of repeats in French talk-in-interaction. Repeats in French are used for initiating repair, as well as for registering receipt. I show for two sequential contexts – after first pair parts and after second pair parts – that the action import of the repeat depends on its prosodic design; prosody allows participants to differentiate between repair-initiating and receipt-registering repeats. While questioning repeats make a response conditionally relevant, registering repeats do not – however, they (...) do not preclude a response either. Registering repeats are sometimes responded to with confirmation tokens, and sometimes not; when produced, such responses are a contingent possibility rather than an expectable second pair part. In the selection and design of confirmation tokens, participants distinguish between solicited and volunteered confirmations. The article relates these findings to prior research on repetition and sequence organisation in French and also in English, Russian and Finnish. (shrink)

abstract G. A. Cohen argues that egalitarians should compensate for expensive tastes or for the fact that they are expensive. Ronald Dworkin, by contrast, regards most expensive tastes as unworthy of compensation — only if a person disidentifies with his own such tastes (i.e. wishes he did not have them) is compensation appropriate. Dworkinians appeal, inter alia, to the so‐called ‘first‐person’ or ‘continuity’ test. According to the continuity test, an appropriate standard of interpersonal comparison reflects people's own assessment of their (...) relative standing: Person A can only legitimately demand compensation from person B if he regards himself as worse off, all things considered, than B. The typical bearer of expensive tastes does not regard herself as being worse off than others with less expensive tastes. Hence, in the typical case, pace Cohen, compensation for expensive tastes is inappropriate. The article scrutinizes this rationale for not compensating for expensive tastes. Especially, we try to bolster the continuity test by relating it to Dworkin's distinction between integrated and detached values, pointing out that an argument for the continuity test can be built on the assumption that equality has integrated value. In brief, the point is that a metric of equality should be assessed, partly, in virtue of its consequences for related ideals. One of these is the kind of justificatory community promoted by the continuity test. We defend this view against an objection to the effect that equality is a detached value. We conclude that the continuity test constitutes a strong foothold for the resourcist egalitarian reluctance to compensate people for their expensive tastes. (shrink)

This paper presents and applies a conceptual framework to address human vulnerability to climate change. Drawing upon social risk management and asset-based approaches, the conceptual framework provides a unifying lens to examine links between risks, adaptation, and vulnerability. The result is an integrated approach to increase the capacity of society to manage climate risks with a view to reduce the vulnerability of households and maintain or increase the opportunities for sustainable development. We identify 'no-regrets' adaptation interventions, meaning actions that generate (...) net social benefits under all future scenarios of climate change and impacts. We also make the case for greater external support for community-based adaptation, discuss the role of social protection, and propose a research agenda. (shrink)

This paper discusses the concept of social affordances in relation to social theory. Our point of departure is the growing literature which posits, in one way or another, that affordances may be seen as social, or cultural or similar. Across the literature on social affordances, it is thus emphasized how perception is shaped within human econiches, how it is fundamentally social, historical, and cultural, but limited direct engagement with decades of scholarship within the social sciences on many of these same (...) topics. This paper thus discusses three key themes for theories of social affordances, exploring sociological perspectives on meaning, place and power, arguing that there may be a difficult, yet fruitful, potential for not just an ecological psychology, but an ecological social science.

This letter addresses the editorial decision to publish the article, “Research on group differences in intelligence: A defense of free inquiry” (Cofnas, 2020). Our letter points out several critical problems with Cofnas's article, which we believe should have either disqualified the manuscript upon submission or been addressed during the review process and resulted in substantial revisions.

This thesis is on information dynamics modeled using *dynamic epistemic logic*. It takes the simple perspective of identifying models with maps, which under a suitable topology may be analyzed as *topological dynamical systems*. It is composed of an introduction and six papers. The introduction situates DEL in the field of formal epistemology, exemplifies its use and summarizes the main contributions of the papers.Paper I models the information dynamics of the *bystander effect* from social psychology. It shows how augmenting the standard (...) machinery of DEL with a decision making framework yields mathematically self-contained models of dynamic processes, a prerequisite for rigid model comparison.Paper II extrapolates from Paper I's construction, showing how the augmentation and its natural peers may be construed as maps. It argues that under the restriction of dynamics produced by DEL dynamical systems still falls a collection rich enough to be of interest. Paper III compares the approach of Paper II with *extensional protocols*, the main alternative augmentation to DEL. It concludes that both have benefits, depending on application. In favor of the DEL dynamical systems, it shows that extensional protocols designed to mimic simple, DEL dynamical systems require infinite representations. Paper IV focuses on *topological dynamical systems*. It argues that the *Stone topology* is a natural topology for investigating logical dynamics as, in it, *logical convergence* coinsides with topological convergence. It investigates the recurrent behavior of the maps of Papers II and III, providing novel insigths on their long-term behavior, thus providing a proof of concept for the approach.Paper V lays the background for Paper IV, starting from the construction of metrics generalizing the Hamming distance to infinite strings, inducing the Stone topology. It shows that the Stone topology is unique in making logical and topological convergens coinside, making it the natural topology for logical dynamics. It further includes a metric-based proof that the hitherto analyzed maps are continuous with respect to the Stone topology. Paper VI presents two characterization theorems for the existence of *reduction laws*, a common tool in obtaining complete dynamic logics. In the compact case, continuity in the Stone topology characterizes existence, while a strengthening is required in the non-compact case. The results allow the recasting of many logical dynamics of contemporary interest as topological dynamical systems. (shrink)

In this paper, we argue that there is at least a pro tanto reason to favor the control account of the right to privacy over the access account of the right to privacy. This conclusion is of interest due to its relevance for contemporary discussions related to surveillance policies. We discuss several ways in which the two accounts of the right to privacy can be improved significantly by making minor adjustments to their respective definitions. We then test the improved versions (...) of the two accounts on a test case, to see which account best explains the violation that occurs in the case. The test turns out in favor of the control account. (shrink)

Framing datafication as new form of knowledge production has become a trope in both academic and commercial contexts. This special theme examines and ultimately rejects the familiar grand claims of datafication, to instead pay attention to emergent conversations that seek to take a more nuanced stock of the status and nature of datafied knowledge production. The articles in this special theme thus engage with datafied knowledge production through elaborate explorations of how datafied knowledge depends on the contexts of its production (...) and the forms of knowledge production that precede it in those contexts. Our basic argument is that while the resources, material features and analytical operations involved in datafied knowledge production may be different, many fundamental concerns about epistemology, ontology and methods remain relevant to understand what shapes it. We still need to understand and explicate the assumptions, operations and consequences of emergent forms of knowledge production. If datafied knowledge production is neither a clean revolutionary break with past forms of knowledge production nor a balloon of pure hype, the articles in this special theme ask: what does the phenomenon of datafied knowledge production look like? Which digital and datafied infrastructures support its future development? And what potentialities and limits do such forms of analysis and knowledge production contain? (shrink)

The Hare Psychopathy Checklist (PCL; Hare, Neumann, & Mokros 2018) scales are among the most widely used forensic assessment tools. Their perceived utility rests partly on their ability to assess stable personality traits indicative of a lack of conscience, which then facilitates behavioral predictions useful in forensic decisions. In this systematic review, we evaluate the empirical evidence behind 3 fundamental justifications for using the PCL scales in forensics, namely, that they are empirically predictive of (1) criminal behavior, (2) treatment outcomes, (...) and (3) a lack of conscience. We found the PCL scales can predict criminal behavior to a statistically significant degree, though with important limitations. We found no evidence of PCL psychopathy being predictive of treatment and rehabilitation outcomes. We found no evidence of PCL psychopathy being predictive of a lack of conscience. These findings disprove widespread beliefs about PCL psychopathy among forensic practitioners and questions the current and future role of the PCL scales in forensic settings. (shrink)

Abstract:This paper examines how second home users perceive their own and aggregate impacts on the environment, while also exploring the justifications they give for such impacts. We combine findings from two Norwegian studies. We find that second home users tend to perceive their own use as less environmentally detrimental than the average use. Positive perceptions about own impacts can partially be explained by the standard of second homes and number of years with access to it. Negative perceptions of aggregate impacts (...) can likewise partially be explained by standard and years with access. Interviewees often justify impacts by relating to popular arguments presented in media and literature. Taking point of departure in a second home perspective, these findings are new to research, but support previous research from tourism studies. Our findings highlight the importance of narratives surrounding second home use and their ability to affect peoples’ perceptions about the environmental friendliness of second homes. (shrink)

Selectionist evolutionary theory has often been faulted for not making novel predictions that are surprising, risky, and correct. I argue that it in fact exhibits the theoretical virtue of predictive capacity in addition to two other virtues: explanatory unification and model fitting. Two case studies show the predictive capacity of selectionist evolutionary theory: parallel evolutionary change in E. coli, and the origin of eukaryotic cells through endosymbiosis.

The last decade has seen an increasing number of references to quantum mechanics in the humanities and social sciences. This development has in particular been driven by Karen Barad’s agential realism: a theoretical framework that, based on Niels Bohr’s interpretation of quantum mechanics, aims to inform social theorizing. In dealing with notions such as agency, power, and embodiment as well as the relation between the material and the discursive level, the influence of agential realism in fields such as feminist science (...) studies and posthumanism has been profound. However, no one has hitherto paused to assess agential realism’s proclaimed quantum mechanical origin including its relation to the writings of Niels Bohr. This is the task taken up here. We find that many of the implications that agential realism allegedly derives from a Bohrian interpretation of quantum mechanics dissent from Bohr’s own views and are in conflict with those of other interpretations of quantum mechanics. Agential realism is at best consistent with quantum mechanics and consequently, it does not capture what quantum mechanics in any strict sense implies for social science or any other domain of inquiry. Agential realism may be interesting and thought provoking from the perspective of social theorizing, but it is neither sanctioned by quantum mechanics nor by Bohr’s authority. This conclusion not only holds for agential realism in particular, it also serves as a general warning against the other attempts to use quantum mechanics in social theorizing. (shrink)

This comment expands on Hooks et al.’s criticism of the problematic and overly general uses of “stress” within the microbiota-gut-brain field.

Blandt de værker, der er overleveret under Platons navn, er den forholdsvis ukendte Theages. Det er en ganske kort dialog, som ikke desto mindre behandler et kernespørgsmål i Platons forfatterskab: Hvordan opnår man visdom? Den har tydelige referencer til en række kendte passager i Platons værk, fx iForsvarstalen, Symposion, Staten og Theaitetos. Desuden viser den nogle af de berømteste sider af Platons Sokrates: Hans guddommelige tegn, hans særlige ironi, hans forhold til sofisterne og til de mennesker, der vil følge ham. (...) Dialogen er både filosofisk og litterært vanskelig at fortolke og er ofte blevet anset for uægte. Den platoniske dialog Theages giver en oversættelse af dialogen, gennemgår dens forskningshistorie og fortolker den gennem en omhyggelig læsning og en diskussion af dens vigtigste temaer. Bogen viser, hvordan de sidste århundreders forskning direkte eller indirekte har været afhængig af spørgsmålet om ægthed. I modsætning hertil argumenterer forfatteren for, at den rette forståelse af dialogen bedst findes på baggrund af Platons samlede værk, uafhængigt af forfatterspørgsmålet. Således giver bogen også et overblik over den nyere Platon-forskning og en indføring i en række væsentlige temaer hos Platon. (shrink)

Distance, it is often argued, is the only coherent and empirically adequate world-making relation that can glue together the elements of the world. This paper offers entanglement as an alternative world-making relation. Entanglement is interesting since it is consistent even with quantum gravity theories that do not feature space at the fundamental level. The paper thereby defends the metaphysical salience of such non-spatial theories. An account of distance is the predominant problem of empirical adequacy facing entanglement as a world-making relation. (...) A resolution of this obstacle utilizes insights from the Ryu–Takayanagi formula and Susskind and Maldacena’s related ER = EPR conjecture. Together these indicate how distance can be recovered from entanglement and thus carves the way for entanglement fundamentalism. (shrink)

I argue that Merleau-Ponty’s use of the case of Schneider in his arguments for the existence of non-conconceptual and non-representational motor intentionality contains a problematic methodological ambiguity. Motor intentionality is both to be revealed by its perspicuous preservation and by its contrastive impairment in one and the same case. To resolve the resulting contradiction I suggest we emphasize the second of Merleau-Ponty’s two lines of argument. I argue that this interpretation is the one in best accordance both with Merleau-Ponty’s general (...) methodology and with the empirical case of Schneider as it was described by Gelb and Goldstein.

Radical naturalized metaphysics wants to argue (1) that metaphysics without sufficient epistemic warrant should not be pursued, (2) that the traditional methods of metaphysics cannot provide epistemic warrant, (3) that metaphysics using these methods must therefore be discontinued, and (4) that naturalized metaphysics should be pursued instead since (5) such science‐based metaphysics succeeds in establishing justified conclusions about ultimate reality. This paper argues that to defend (5), naturalized metaphysics must rely on methods similar to those criticized in (2). If naturalized (...) metaphysics instead opts for the weaker claim that science‐based metaphysics is only superior to other metaphysics, then this is insufficient to establish (4). In this case, (4) might therefore be defeated by (1). An alternative is to replace (1) with the view that we should just approach metaphysical questions with the best means available. While this would recommend a science‐based approach whenever possible, it would also allow for the continuation of science‐independent metaphysics in domains that science has no bearing on and thus reject (3). The paper concludes that none of these alternatives is entirely satisfactory for naturalized metaphysics. (shrink)

Liberal egalitarianism is commonly criticized for being insufficiently sensitive to status inequalities and the effects of misrecognition. I examine this criticism as it applies to Ronald Dworkin’s ‘equality of resources’ and argue that, in fact, liberal egalitarians possess the resources to deal effectively with recognition-type issues. More precisely, while conceding that the distributive principles required to realize equality of resources must apply against a particular institutional background, I point out, following Dworkin, that among the principles guiding this background is a (...) ‘principle of independence,’ and that this principle, properly interpreted, requires government to protect people against the disadvantageous effects of wrongful prejudicial discrimination. Moreover, I give an account of wrongful prejudice which is grounded in a particular interpretation of the abstract egalitarian principle Dworkin requires for a government to be legitimate and which goes a long way toward acknowledging status inequalities. Finally, I suggest other resources within the theory for responding to residual problems of recognition not addressed by the principle of independence. (shrink)

The term psychopathy refers to a personality disorder associated with callous personality traits and antisocial behaviors. Throughout its research history, psychopathy has frequently been described as a peculiar form of moral blindness, engendering a narrative about a patient stereotype incapable of taking a genuine moral perspective, similar to a blind person who is deprived of proper visual perceptions. However, recent empirical research has shown that clinically diagnosed psychopaths are morally more fit than initially thought, and the blindness-analogy now comes across (...) as largely misleading. In this contribution, the moral-blindness analogy is explored in an attempt to qualify anew its relevance in psychopathy theory and research. It is demonstrated that there are indeed theoretically relevant parallels to be drawn between blindness and psychopathy, parallels that are especially illuminating when accounting for the potential symptomatology, dimensionality, and etiological nature of the disorder.

In this paper, we argue that what is often discussed under the umbrella of `spacetime emergence' in the philosophy of quantum gravity in fact consists of a plethora of distinct and even highly different problems. We therefore advocate to cast such debates more specifically in terms of the emergent spatiotemporal aspects, as is already done in the physics literature. We first show how ambiguous the notion of spacetime is already in general relativity. We then argue against three ways to reject (...) our call for specificity: the many distinct philosophical problems relating to the emergence of the various spatiotemporal aspects do not suggest any singular, overarching, or exceptional problem of spacetime emergence. We also discuss how the objections are reflected by five conceptions of spacetime. Next, we observe that different spatiotemporal aspects are emergent in the different quantum gravity approaches, whereby investigating emergence in quantum gravity collectively is problematic. Finally, we illustrate how philosophical inquiries that employ notions of spacetime emergence are aided by conducting the investigation at the level of specific spatiotemporal aspects. (shrink)

While structural approaches to sustainability have remained unable to muster wider political support, green political theory has for some time taken a voluntarist turn, arguing that deep changes in attitudes and behaviour are necessary to reduce the ecological debt of the rich countries. Within environmental citizenship theory it is believed that justice requires each individual to start living within his or her 'ecological space'. Firmly rooted in the pollution paradigm, environmental citizenship theory holds that the path to sustainability goes through (...) a dramatic reduction in economic activity and international trade. Since such cuts in material welfare run counter to the preferences of many, doubts can be had about their political plausibility. More seriously, with a world population of more than seven billions, it is doubtful that even such harsh sacrifices would suffice to ensure environmental sustainability. This article challenges environmental citizenship theory by arguing that it is tied to a conception of sustainability which is both theoretically misleading and strategically unfortunate in a rapidly industrialising world. Instead of further individual guilt, there is an urgent need to define new collective progressive projects aimed at universal affluence and natural restoration. Fashionable as a sense of individual guilt may be, it fails to recognise the responsibility of the rich world to provide new technologies capable of securing global environmental sustainability.
