Full ectogenesis as the complete externalization of human reproduction by bypassing the bodily processes of gestation and childbirth can be considered the culmination of genetic and reproductive technologies. Despite its still being a hypothetical scenario, it has been discussed for decades as the ultimate means to liberate women from their reproductive tasks in society and hence finally end fundamental gender injustices generally. In the debate about the application of artificial wombs to achieve gender equality, one aspect is barely mentioned but (...) is of crucial relevance from a medical‐ethical perspective: whether and how could full ectogenesis be justified as a proper use of medicine? After characterizing the technology as a special form of human enhancement and as an extension of medical practice that goes beyond the traditional field of medicine, this paper critically assesses the theoretical possibilities of legitimizing this extension. We identify two ways of justification: either one argues that ectogenesis fulfils a proper goal of medicine (a justification we call pathologization), or one argues that the application of ectogenesis achieves a non‐medical goal (which we call medicalization). Because it is important from a medical‐ethical point of view to avoid an inappropriate instrumentalization or misuse of medicine and thus an undue medicalization of non‐medical problems, a set of necessary conditions has to be met. It is doubtful whether full ectogenesis for non‐medical purposes could fulfil these conditions. Rather, its comprehensive usage could be seen as a revolutionary modification of what it means to be human. (shrink)

Notwithstanding the success of conventional field trials for vaccines against COVID-19, human challenge trials that could obtain more information about these and about other vaccines and further strategies against it are about to start in the UK. One critique of COVID-19 HCTs is their distinct paucity of information on crucial population groups. For safety reasons, these HCTs will exclude candidate participants of advanced age or with comorbidities that worsen COVID-19, yet a vaccine should protect such populations. We turn this cliché (...) on its head. The truth is that either an HCT or a field trial has intrinsic generalisability limitations, that an HCT can expedite protection of high-risk participants even without challenging them with the virus, and that an important route to obtaining results generalisable to high-risk groups under either strategy is facilitated by HCTs. There are no data in this work. (shrink)

Saying so can make it so, J. L. Austin taught us long ago. Famously, John Searle has developed this Austinian insight in an account of the construction of institutional reality. Searle maintains that so-called Status Function Declarations, allegedly having a “double direction of fit”, synchronically create worldly institutional facts, corresponding to the propositional content of the declarations. I argue that Searle’s account of the making of institutional reality is in tension with the special theory of relativity—irrespective of whether the account (...) is interpreted as involving causal generation or non-causal grounding of worldly institutional facts—and should be replaced by a more modest theory which interprets the results of Status Function Declarations in terms of mere Cambridge change and institutional truth. I end the paper by indicating the import of this more modest theory for theorizing about the causal potency of institutional phenomena generated by declarations. (shrink)

Over the last few decades, philosophers and social scientists have applied the so-called powers ontology to the social domain. I argue that this application is highly problematic: many of the alleged powers in the social realm violate the intrinsicality condition, and those that can be coherently taken to be intrinsic to their bearers are arguably causally redundant. I end the paper by offering a diagnosis of why philosophers and social scientists have been tempted to think that there are powers in (...) social realm. (shrink)

Many powers metaphysicians postulate both active and passive powers, understood as distinct kinds of intrinsic causal properties of objects. I argue that the category of passive power is superfluous. I also offer a diagnosis of how philosophers are misled to postulate passive powers.

In this paper I explore how the tenseless copula is to be interpreted in sentences of the form “a is F at t”, where “a” denotes a persisting, changeable object, “F” stands for a prima facie intrinsic property and “t” for a B-time. I argue that the interpretation of the copula depends on the logical role assigned to the time clause. Having rejected the idea that the time clause is to be treated as a sentence operator, I argue: that if (...) “at t” is thought of as being associated with “a” or “F”, then the tenseless copula is most plausibly read as an “is” simpliciter; and that if “at t” is treated as being associated with the copula, then the tenseless copula is most plausibly understood as expressing a disjunction of tensed copulas. I end the paper by explaining the importance of the issue. I indicate the ramifications interpretation of the tenseless copula has for the so-called problem of temporary intrinsics. (shrink)

Consciousness is targeted by both philosophers and neuroscientists; but different methodological premises and even different conceptions about what conscious experience is and how the challenges and potential problems associated with consciousness research should be formulated underlie the different approaches. Namely, whereas empirical data and the constant refinement of experimental procedures to expand and modify this body of empirical data and resulting empirical theories are crucial to neuroscience, the significance of empirical knowledge to philosophy is less clear: Although empirical data certainly (...) can influence philosophical concepts, the latter are nonetheless prerequisites of empirical research itself and thus may themselves not be empirically testable. The present paper elaborates from a multidisciplinary, neuroscientist-philosopher’s perspective the relation of philosophical concepts and empirical research on consciousness, drawing on two exemplary controversies from the philosophy of mind – on the ontological status of experiential properties and on free will. Consequences from both the scientific and the philosophical standpoint are discussed. (shrink)

León and Zahavi (2023) have made a compelling case for the necessity of philosophy — and not only neuroscience — for investigating consciousness. In particular, they argue that any theory of consciousness cannot avoid philosophical enquiry and thus only can choose between good or bad philosophy. Also, the topics of self-consciousness and selfhood are highlighted as problems of consciousness sui generis next to the mind–body problem. I will try to elucidate a bit more the specific approaches to consciousness that philosophy (...) and neuroscience take and thus elaborate why the philosophy and the neuroscience of consciousness are complimentary rather than mutually exclusive.

Setting off from a familiar distinction in the philosophy of properties, this paper introduces a tripartite distinction between sparse causation, abundant causation and mere abundant causation. It is argued that the contrast between sparse and mere abundant causation allows us to resolve notorious philosophical issues having to do with negative causation, causation involving institutional properties and physical macro-causation in a way that is unified, intuitive and in line with scientific doctrines and practices.

I argue that Mumford and Anjum’s recent theory of simultaneous causation among powerful meso-level objects is problematic in several respects: it is based on a false dichotomy, it is incompatible with standard meso-level physics, it is explanatory deficient, and it threatens to render the powers metaphysics incoherent. Powers theorists are advised, therefore, to adopt a purely sequential conception of causation.

I outline a deflationary truthmakers account of social groups. Potentially, the approach allows us to say, with traditional ontological individualists, that there are only pluralities of individuals out there, ontologically speaking, but that there are nevertheless colloquial and social-scientific truths about social groups. If tenable, this kind of theory has the virtue of being both ontologically parsimonious and compatible with ordinary and social-scientific discourse—a virtue which the stock reductive / ontological dependence accounts of social groups arguably lack.

Excellence and frontier research have made inroads into European research policymaking and structure political agendas, funding programs and evaluation practices. The two concepts travelled a long way from the United States and have derived from contexts outside of science. Following their conceptual journey, we ask how excellence and frontier research have percolated into European science and higher education policies and how they have turned into lubricants of competition that buttress an ongoing reform process in Europe.

David Chalmers has distinguished the “hard” and the “easy” problem of consciousness, arguing that progress on the “easy problem”—on pinpointing the physical/neural correlates of consciousness—will not necessarily involve progress on the hard problem—on explaining why consciousness, in the first place, emerges from physical processing. Chalmers, however, was hopeful that refined theorizing would eventually yield philosophical progress. In particular, he argued that panpsychism might be a candidate account to solve the hard problem. Here, I provide a concise stock-take on both the (...) empirical-neuroscientific and philosophical-conceptual progress on consciousness. It turns out that, whereas empirical progress is indisputable, philosophical progress is much less pronounced. While Chalmers was right, I argue, in distinguishing distinctive types of problems of consciousness, his prediction of progress on the hard problem was overly optimistic. Empirical progress and philosophical progress are essentially uncoupled; a more skeptical perspective on progress in philosophy in general is appropriate. (shrink)

Three arguments for the conclusion that objects cannot endure in B-time even if they remain intrinsically unchanged are examined: Carter and Hestevolds enduring-objects-as-universals argument (American Philosophical Quarterly 31(4):269-283, 1994) and Barker and Dowe's paradox 1 and paradox 2 (Analysis 63(2):106-114, 2003, Analysis 65(1):69-74, 2005). All three are shown to fail.

In this note, we point attention to and briefly discuss a curious manuscript of Einstein, composed in 1938 and entitled “Unified Field Theory,” the only such writing, published or unpublished, carrying this title without any further specification. Apparently never intended for publication, the manuscript sheds light both on Einstein′s modus operandi as well as on the public role of Einstein′s later work on a unified field theory of gravitation and electromagnetism.

This thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. It is a widespread view among philosophers that if we accept the B-theory, the commonsensical ‘endurance theory’ of persistence will have to be rejected. The endurance theory says (...) that objects persist through time by being wholly present at distinct times as numerically the same entity. Instead of endurantism, it has been argued, we have to adopt either ‘perdurantism’ or the ‘stage theory’. Perdurantism is the theory that objects are four-dimensional ‘space-time worms’ persisting through time by having distinct temporal parts at distinct times. The stage theory says that objects are instantaneous temporal parts (stages) of space-time worms, persisting by having distinct temporal counterparts at distinct times. In the thesis, it is argued that no good arguments have been provided for the conclusion that we are obliged to drop the endurance theory by acceptance of the B-theory. This conclusion stands even if the endurance theory incorporates the claim that objects endure through intrinsic change. It is also shown that perdurantism and the stage theory come with unwelcome consequences. -/- Paper I demonstrates that the main arguments for the view that objects cannot endure in B-time intrinsically unchanged fail. Papers II and III do the same with respect to the traditional arguments against endurance through intrinsic change in B-time. Paper III also contains a detailed account of the semantics of the tenseless copula, which occurs frequently in the debate. The contention of Paper IV is that four-dimensional space-time worms, as traditionally understood, are not suited to take dispositional predicates. In Paper V, it is shown that the stage theory needs to introduce an overabundance of persistence-concepts, many of which will have to be simultaneously applicable to a single object (qua falling under a single sortal), in order for the theory to be consistent. The final article, Paper VI, investigates the sense in which persistence can, as is sometimes suggested, be a ‘conventional matter’. It also asks whether alleged cases of ‘conventional persistence’ create trouble for the endurance theory. It is argued that conventions can only enter at a trivial semantic level, and that the endurance theory is no more threatened by such conventions than are its rivals. (shrink)

This paper discusses social mechanisms of discrimination and reviews existing field experimental designs for their identification. We first explicate two social mechanisms proposed in the literature, animus-driven and statistical discrimination, to explain differential treatment based on ascriptive characteristics. We then present common approaches to study discrimination based on observational data and laboratory experiments, discuss their strengths and weaknesses, and elaborate why unobtrusive field experiments are a promising complement. However, apart from specific methodological challenges, well-established experimental designs fail to identify the (...) mechanisms of discrimination. Consequently, we introduce a rapidly growing strand of research which actively intervenes in market activities varying costs and information for potential perpetrators to identify causal pathways of discrimination. We end with a summary of lessons learned and a discussion of challenges that lie ahead. (shrink)

ZUSAMMENFASSUNGDer Aufsatz geht davon aus, dass Charles Taylors viel beachtetes Werk Ein säkulares Zeitalter neben verschiedenen anderen Erkenntnisinteressen auch auf eine ›religionsphilosophische Rehabilitierung der christlichen Religion‹ zielt. Es wird darum das Verfahren, mit dem Taylor dabei zu Werke geht, auf seine argumentativen Gehalte hin rekonstruiert und auf einige neuralgische Punkte aufmerksam gemacht. Die wesentliche These ist dabei, dass – unbeschadet aller Errungenschaften des Buchs – Fragen der Geltung in Taylors Religionsphilosophie letztlich zu kurz kommen.SUMMARYThe article assumes that Charles Taylor's highly (...) acclaimed A Secular Age attempts, in addition to several other interests, to offer a ›religio-philosophical rehabilitation of the Christian religion‹. Therefore, Taylor's chain of reasoning is reconstructed in regards to its argumentative content and attention is drawn to some critical points of his approach. In sum, the article's main thesis is that – notwithstanding all the achievements of Taylor's A Secular Age – questions of the validity in Taylor's philosophy of religion ultimately come up too short.

This study explores the evolutionary-based hypothesis that facial attractiveness (a guiding force in mate selection) is a cue for physical fitness (presumably an important contributor to mate value in ancestral times). Since fluctuating asymmetry, a measure of developmental stability, is known to be a valid cue for fitness in several biological domains, we scrutinized facial asymmetry as a potential mediator between attractiveness and fitness. In our sample of young women, facial beauty indeed indicated physical fitness. The relationships that pertained to (...) asymmetry were in the expected direction. However, a closer analysis revealed that facial asymmetry did not mediate the relationship between fitness and attractiveness. Unexpected problems regarding the measurement of facial asymmetry are discussed. (shrink)

Words whose consonantal articulation places move from the front of the mouth to the back (e.g. BADAKA; inward) receive more positive evaluations than words whose consonantal articulation places move from the back of the mouth to the front (e.g. KADABA; outward). This in–out effect has a variety of affective, cognitive, and even behavioural consequences, but its underlying mechanisms remain elusive. Most recently, a linguistic explanation has been proposed applying the linguistic easy-first account and the so-called labial-coronal effect from developmental speech (...) research and phonology to the in–out effect: Labials (front) are easier to process than coronals (middle); and people prefer easy followed by harder motor components. Disentangling consonantal articulation direction and articulation place, the present three preregistered experiments (total N = 1012) found in–out effects for coronal-dorsal (back), and labial-dorsal articulation places. Critically, no in–out effect emerged for labial-coronal articulation places. Thus, the in–out effect is unlikely an instantiation of easy first. (shrink)

In recent debates surrounding World Health Organization reform, international lawmaking has received unprecedented attention as a future priority function of the Organization. Although WHO's constitutional lawmaking authority was historically neglected and even resisted by WHO and its Member States until the adoption of its first treaty a decade ago, the widespread consensus in favor of a central role for lawmaking in visions of a reformed WHO reflects the crystallization of contemporary approaches to global health governance. Today it is widely recognized (...) that the trends toward globalization that have restricted the capacity of sovereign states to protect health through unilateral action alone have made innovative mechanisms to promote global cooperation and coordination, including international lawmaking, an essential component of governance of public health.

Cigarette smoking and other addictive behaviors are among the main preventable risk factors for several severe and potentially fatal diseases. It has been argued that addictive behavior is controlled by an automatic-implicit cognitive system and by a reflective-explicit cognitive system, that operate in parallel to jointly drive human behavior. The present study addresses the formation of implicit attitudes towards smoking in both smokers and non-smokers, using a Go/NoGo association task, and behavioral and electroencephalographic measures. The GNAT assesses, via quantifying participants’ (...) reaction times, the strength of association between a target category and either pole of an evaluative dimension. EEG analysis is performed to determine the temporal course of the event-related potential components underlying Go/NoGo decisions and implicit attitude formation. Both smokers and non-smokers showed prolonged reaction times to smoking-related pictures when the pictures were coupled with positive evaluative words. This indicates negative implicit attitudes towards smoking in both groups alike at the time point of the behavioral response. However, only the non-smokers, not the smokers, were found to show a delay of the N200 component in the incongruent condition. This is interpreted as reflecting ambivalent or even positive implicit attitudes towards smoking in the smoker group at the time point of the N200. Our study thus provides evidence for the hypothesis that implicit attitudes are subject to changes within several hundred milliseconds after stimulus presentation, and can be altered in the course of their formation.

Extensive research has demonstrated that rs1360780, a common single nucleotide polymorphism within the FKBP5 gene, interacts with early-life stress in predicting psychopathology. Previous results suggest that carriers of the TT genotype of rs1360780 who were exposed to child abuse show differences in structure and functional activation of emotion-processing brain areas belonging to the salience network. Extending these findings on intermediate phenotypes of psychopathology, we examined if the interaction between rs1360780 and child abuse predicts resting-state functional connectivity (rsFC) between the amygdala (...) and other areas of the salience network. We analyzed data of young European adults from the general population (N = 774; mean age = 18.76 years) who took part in the IMAGEN study. In the absence of main effects of genotype and abuse, a significant interaction effect was observed for rsFC between the right centromedial amygdala and right posterior insula (p <.025, FWE-corrected), which was driven by stronger rsFC in TT allele carriers with a history of abuse. Our results suggest that the TT genotype of rs1360780 may render individuals with a history of abuse more vulnerable to functional changes in communication between brain areas processing emotions and bodily sensations, which could underlie or increase the risk for psychopathology.

Throughout the last decade, calls for a return to materiality have reverberated within the humanities and social sciences. Few, however, have noticed that this return has also entailed a return to fiction, as the new theoretical writings on matter regularly include elements of storytelling, fabulation or other genres of invention. This article asks why this alliance between new materialism and fiction has come about: Why do scholars united by a common interest in ‘getting real’ consistently utilize a type of discourse (...) defined precisely by not committing itself to reality? Examining works by Jane Bennett, Dominic Pettman, Stacy Alaimo, Astrida Neimanis, Donna Haraway, and Rebekah Sheldon, the article explores this question by tracing three modes of fictionality in new materialism distinguished by inventing non/human entanglements, scientific knowledge, and future societies respectively. Ultimately, the article argues that fictionality is a particularly attractive tool for attempts to transcend anthropocentric regimes of truth. (shrink)
