Graphical AbstractIn article number 2000050, Barbora Straková et al. speculate that environmental sex determination in amniotes evolves via a heterochronic shift of sex change from the adult to the embryonic stage in a hermaphroditic ancestor. Subsequently, the loss of responsiveness to environmental stimuli (stress) led to genotypic sex determination, where the sex is decided at conception. Cover image by Tereza Unzeitigova.

Frequent independent origins of environmental sex determination (ESD) are assumed within amniotes. However, the phylogenetic distribution of sex‐determining modes suggests that ESD is likely very ancient and may be homologous across ESD groups. Sex chromosomes are demonstrated to be old and stable in endothermic (mammals and birds) and many ectothermic (non‐avian reptiles) lineages, but they are mostly non‐homologous between individual amniote lineages. The phylogenetic pattern may be explained by ancestral ESD with multiple transitions to later evolutionary stable genotypic sex determination. (...) It is pointed out here that amniote ESD shares several key aspects with sequential hermaphroditism of fishes such as a lack of sex differences in genomes, biased population sex ratios, and potentially also molecular mechanism related to general stress responses. Here, it is speculated that ESD evolves via a heterochronic shift of the sensitive period of sex change from the adult to the embryonic stage in a hermaphroditic amniote ancestor.

Using the technique of prepared questions, Conversations with Lukacs is a brilliant gathering of thoughts and insights covering topics as ontology, the techniques of manipulative societies, the pitfalls of combating Stalinism with Stalinist methods, and the problems of intellectuals in advanced capitalist societies. Above all, there is the restatement of Lukacs unshaken conviction that the working class, with all the changes that have occurred in its way of life and composition, is still the historical carrier of social transformation. Lukacs's interlocutors (...) in these four conversations are Hans Heinz Holz, Leo Kofler, and Wolfgang Abendroth. Each of them engages Lukacs in separate dialogues, on being and consciousness (Holz), on society and the individual (Kofler), and on the elements of scientific politics (Abendroth). Lukacs, Abendroth, and Holz work toward a "Provisional Summary" in the last conversation. The interlocutors and the editor write that "These conversations show very clearly the basis of abstraction in the experiences of everyday life.... This gives these conversations with Lukacs a more than anecdotal value; for the unmediated way in which thought is produced in conversation corresponds exactly to that primary level of experience, the data of everyday reality, whose theoretical value Lukacs emphasizes.... They aspire to bear witness to the living thought of one of the great men of our century, and to provide the opportunity to approach this thought by the simplest possible route.". (shrink)

Carbon pricing is one of the most politically important approaches for the mitigation of climate change in the world today. Most political actors who are not committed to climate change denial favor carbon pricing, either as emissions trading or carbon taxation. In this article, I argue that carbon pricing should be considered unfair in most of its forms. I present a line of criticism called the Unfair Burdens Argument. It states that the most politically relevant ways to price carbon needlessly (...) burden the less affluent more than the more affluent. This is unfair because, among other things, the more affluent have on average done more to create the problem of climate change in the first place. Principles for the fair distribution of burdens under climate change mitigation like the Polluter Pays Principle, which were thought to support carbon pricing, turn out to speak against it, when interpreted properly. Although the Unfair Burdens Argument on its own cannot show that carbon pricing is impermissible, it offers important clues for what a morally permissible form of climate change mitigation would look like.

ABSTRACT This essay examines the exhibition of dinosaurs at the American Museum of Natural History during the first two decades of the twentieth century. Dinosaurs provide an especially illuminating lens through which to view the history of museum display practices for two reasons: they made for remarkably spectacular exhibits; and they rested on contested theories about the anatomy, life history, and behavior of long-extinct animals to which curators had no direct observational access. The American Museum sought to capitalize on the (...) popularity of dinosaurs while mitigating the risks of mounting an overtly speculative display by fashioning them into a kind of mixed-media installation made of several elements, including fossilized bone, shellac, iron, and plaster. The resulting sculptures provided visitors with a vivid and lifelike imaginative experience. At the same time, curators, who were anxious to downplay the speculative nature of mounted dinosaurs, drew systematic attention to the material connection that tied individual pieces of fossilized bone to the actual past. Freestanding dinosaurs can therefore be read to have functioned as iconic sculptures that self-consciously advertised their indexical content. (shrink)

One of the most pressing points in the philosophy of sport is the question of a definition of sport. Approaches towards sport vary based on a paradigm and position of a particular author. This article attempts to analyse and critically evaluates a recent definition of sport presented by Jim Parry in the context of argument that e-sports are not sports. Despite some innovations, his conclusions are in many ways traditional and build on the previous positions. His research, rooted in the (...) conceptual analysis, starts with a stipulation that sport is paradigmatically Olympic sport. He defines it then as an ‘institutionalised, rule-governed contest of human physical skill’ i.e., identifies six necessary elements of sport: human (not animals), physical (not chess), skill (not jogging), contest (not mountaineering), rule-governed (not ‘field sports’), institutionalized (not hula-hooping). Our claim is that this definition, despite its methodological clarity, is not accurate and does not sufficiently represent sport outside the Olympic context. First, to say for something to be a sport it is necessary to be a contest leads to a narrow concept of sport. Secondly, Parry’s account lacks the emphasis on game and play-like structures that are inherently present in sport (even in the Olympic sport), namely non-necessity, non-ordinariness, arbitrariness and gratuitousness. We try to direct the attention precisely on these structures and offer an alternative account of sport understood as a modern ‘hard core’ sport that nevertheless reaches important congruences with Parry’s definition. The originality of this contribution lies in presenting the essential qualities of modern ‘hard core’ sports, which, although sometimes hidden in the modern emphasis on high level performances, competition, and results, play an important role in the question how sport ought to be played and approached.

The extent of our duties to mitigate climate change is commonly conceptualized in terms of temperature goals like the 1.5°C and the 2°C target and corresponding emissions budgets. While I do acknowledge the political advantages of any framework that is relatively easy to understand, I argue that this particular framework does not capture the true extent of our mitigation duties. Instead I argue for a more differentiated approach that is based on the well-known distinction between subsistence and luxury emissions. At (...) the heart of this approach lies the argument that we have no budget of substantial, net-positive luxury emissions left. In a world in which dangerous climate change has begun, we must expect all further substantial, net-positive luxury emissions to cause harm. Since they lack the kind of justification needed for them to be nevertheless permissible, I conclude that we must stop emitting them with immediate effect. I also briefly discuss the difficult case of subsistence emissions and offer some first thoughts on the morality of a third category of emissions, what I call ‘transition emissions’. (shrink)

Machine intelligence already helps medical staff with a number of tasks. Ethical decision-making, however, has not been handed over to computers. In this proof-of-concept study, we show how an algorithm based on Beauchamp and Childress’ prima-facie principles could be employed to advise on a range of moral dilemma situations that occur in medical institutions. We explain why we chose fuzzy cognitive maps to set up the advisory system and how we utilized machine learning to train it. We report on the (...) difficult task of operationalizing the principles of beneficence, non-maleficence and patient autonomy, and describe how we selected suitable input parameters that we extracted from a training dataset of clinical cases. The first performance results are promising, but an algorithmic approach to ethics also comes with several weaknesses and limitations. Should one really entrust the sensitive domain of clinical ethics to machine intelligence? (shrink)

We investigate the determinants of decision rights transfer and its effects on the motivation of an agent. The study is based on a laboratory experiment conducted on 130 subjects playing an innovative principal–agent game. Interestingly, the results show that agents do not favour a delegation and a decision is considered rather burdensome. Although the experiment could not give support for the behavioural hypothesis of higher effort provided by participants who receive choice subsequently, the survey illuminates the interaction between delegation motives, (...) effort motivators, goals and other perceptions of the agents.

Článek se zabývá komparací předpokladů rakouské školy a ekonomie hlavního proudu se zaměřením na jejich realističnost a důsledky plynoucími z odlišnosti těchto předpokladů. Hlavní pozornost je věnována rozdílnému chápání role a způsobu získávání informací. Předpoklady ekonomie hlavního proudu jsou na základě uvedené argumentace označeny za záměrně nereálné proto, aby vyhovovaly matematickým modelům. Dále jsou analyzovány dopady matematizace ekonomie, zejména v kontextu jejího využití pro predikce ekonomického vývoje.

Wright (1998) and Bar-On (2004) put pressure on the idea that self-knowledge as an explanandum should be identified with privileged belief formation. They argue that setting up the discourse on the level of belief and belief formation rules out promising approaches to explain self-knowledge. Hence, they propose that we should characterize self-knowledge on the level of linguistic practice instead. I argue against them that self-knowledge cannot be fully characterized by features of our linguistic practice. I propose that in some circumstances (...) – disagreements about one's mental states – self-knowledge plays a role, but this role cannot be described in virtue of features of our linguistic practice. I consider three objections to the argument and conclude that we should not conceive self-knowledge solely in terms of linguistic practice. (shrink)

What is the practical relevance of the Non-Identity Problem (NIP) for our climate change-related duties? Climate change and the NIP are often discussed together, but there is surprisingly little work on the practical relevance of the NIP for the ethics of climate change. The central claim of this article is that the NIP makes a relatively minor difference to our climate change-related duties even if we pursue what has become known as the ‘bite the bullet’ strategy: endorse a person-affecting view (...) threatened by the NIP and not modify it in such a way as to evade the NIP. In particular I will argue that a harm-based view can justify the big-picture call for action emerging from the field of climate ethics. The key to reaching this conclusion is pointing out the consequences of our climate change-related decisions for people whose existence does not depend on these very decisions. (shrink)

The acceptability of _any_-DPs in existential modal sentences presents a challenge for theories of NPI licensing: existential modal sentences appear to differ substantially from other environments in which _any_-DPs are acceptable (in particular, they lack a downward-entailing operator). One approach to this challenge has been to, first, take _any_-DPs to be subject to an environment-based downward-entailingness condition—they have to occur in an environment that is Strawson downward-entailing with respect to their domain (cf. Kadmon and Landman 1993 )—and, second, to derive (...) such an environment in existential modal sentences by means of exhaustification (e.g., Fox 2007 ). This note presents new evidence for such a two-layered approach (cf. Crnič 2017, 2019 ). The evidence comes from a striking contrast in the behavior of singular vs. plural _any_-DPs in existential modal sentences. The paper concludes by charting some relations between _any_-DPs and other polarity items. (shrink)

According to Frege, expressions shift their reference when they occur in indirect contexts: in “Anna believes that Plato is wise” the expression “Plato” no longer refers to Plato but to what is ordinarily its sense. Many philosophers, including Carnap, Davidson, Burge, Parsons, Kripke and Künne, believe that on Frege's view the iteration of indirect context creating operators gives rise to an infinite hierarchy of senses. While the former two take this to be problematic, the latter four welcome the hierarchy with (...) open arms. In this paper I argue that the hierarchy should be avoided and that it can be avoided.

When an individual is comatose while parts of her brain remain functional, the question arises as to whether any mental characteristics are still associated with this brain, that is, whether the person still exists. Settling this uncertainty requires that one becomes clear about two issues: the type of functional loss that is associated with the respective profile of brain damage and the persistence conditions of persons. Medical case studies can answer the former question, but they are not concerned with the (...) latter. Conversely, in the philosophical literature, various accounts of personal identity are discussed, but usually detached from any empirical basis. Only uniting the two debates and interpreting the real-life configurations of brain damage through the lens of the philosophical concepts enables one to make an informed judgment regarding the persistence of comatose persons. Especially challenging are cases in which three mental characteristics that normally occur together—wakefulness, awareness and memory storage—come apart. These shall be the focus of this paper.

Following the work of Peter Schmitt-Egner, this article lays out a value-form theoretical approach to racism. During the debates within German Marxism on the reconstruction of the critique of political economy (Neue Marx-Lektüre), Schmitt-Egner developed a theory in the 1970s that tries to explain racism with reference to Marx’s analysis of the commodity form and circulation. Thereby he developed a highly original theoretical derivation of racism as an ideological reification of the debased position of colonised labour power in comparison with (...) that of metropolitan workers. The bourgeois ideals of freedom and equality, constituted through commodity circulation, according to Schmitt-Egner, are modified by the nature of the colonial production process and thus negated in the case of the racialised worker. Even if his theory, as I am going to show, has some serious flaws, it helps to make sense of past and current patterns of racist inferiorisation. (shrink)

Expectations play an important role in how people plan their lives and pursue their projects. People living in highly industrialized countries share a way of life that comes with high levels of emissions. Their expectations to be able to continue their projects imply their holding expectations to similarly high future levels of personal emissions. We argue that the frustration or undermining of these expectations would cause them significant harm. Further, the article investigates under what conditions people can be thought to (...) hold legitimate expectations, in particular about permissible levels of future emissions. We distinguish differing theories of understanding these conditions, namely authority-based and justice-based theories, that each allows us to systematically distinguish between legitimate and illegitimate expectations. Furthermore, with respect to individuals’ future permissible emissions we give several reasons for holding that such theories cannot identify a particular expectation to a specific level of personal emissions as the only legitimate one. Finally, we argue that the set of legitimate expectations that people hold with respect to a just and effective solution to climate change has normative significance in at least two ways: the differing but equally legitimate expectations ought to be taken into account when justifying what could count as such a solution and when determining the just way of arriving at and implementing such a solution.

Gibt es überzeugende Überforderungseinwände gegen anspruchsvolle moralische Auffassungen? In diesem Buch werden Überforderungseinwände präzise charakterisiert, systematisch eingeordnet und argumentativ verteidigt. Unter Berücksichtigung der wichtigsten philosophischen Beiträge zum Thema wird gezeigt, weshalb gewisse Moraltheorien und -prinzipien dafür kritisiert werden können, dass sie zu viel von einzelnen Personen verlangen.

Subverting a once widely held Quinean paradigm, there is a growing consensus among philosophers of logic that higher-order quantifiers (which bind variables in the syntactic position of predicates and sentences) are a perfectly legitimate and useful instrument in the logico-philosophical toolbox, while neither being reducible to nor fully explicable in terms of first-order quantifiers (which bind variables in singular term position). This article discusses the impact of this quantificational paradigm shift on metaphysics, focussing on theories of properties, propositions, and identity, (...) as well as on the metaphysics of modality.

The literature on Base of the Pyramid strategies emphasizes that creating social value requires collaborative, multi-stakeholder business approaches. However, there is limited understanding of how businesses can successfully coordinate such value creation processes in the developing economies that face significant institutional voids. This study adopts a business model perspective for analyzing social value creation processes that span organizational boundaries. We introduce a novel, theoretically grounded business model framework that helps conceptualize social value by locating the various loci of value creation, (...) and the stakeholders that partake in creating and capturing this value. We subsequently analyze the mechanisms of social value creation in M-Pesa, a renowned boundary-spanning mobile money system that has advanced financial inclusion among tens of millions of users in Kenya. The results show that information and communications technology can help advance social value creation by reducing the cost of coordinating boundary-spanning business models that integrate diverse societal stakeholders. The results further point to uneven distributional outcomes in self-governing social value creation strategies where the focal firm plays a coordinating role. (shrink)

In this paper, I consider Patricius’s argument on integrality laid out in “Pampsychia”, least researched book belonging to Nova universis philosophia, in comparison with the notions, methodologies and pragmatic reach of the contemporary science of human psyche. I attempted to determine can the argument correspond to the methodological instrument of psychology or the relation is disjunctive, that is, in animosity. I emphasise Patricius’s reflection on the mindcenteredness of the soul while trying to point at the dynamic and dialectical character of (...) the psyche phenomenon as the fundamental determinant of Patricius’s psycho­ontology and the importance of implementing philosophical reflection into the mental health system framework, as a precondition for the holistic, integrative approach to the problem.

The distinction between voluntarism and intellectualism has recently been criticized for inaccurately characterising early modern theories of divine freedom. In response, defenders of the distinction have argued that these labels are needed in order to account for the famous correspondence between Leibniz (intellectualist) and Clarke (voluntarist). In this paper, I argue that the voluntarism/intellectualism distinction is unable to account for the opposition between Leibniz and Clarke. In the first part, I provide an analysis of Clarke’s theory of divine freedom, and (...) show how he employs the distinction between activity and passivity in order to account for the separation between God’s will and intellect, which ultimately safeguards God’s freedom. I also analyse Clarke’s correspondence with Leibniz, and show how Clarke deals with choice among equals, the principle of sufficient reason, and the principle of the best. In the second part, I argue on the basis of this analysis that Clarke is not a voluntarist, but should instead be interpreted as an intellectualist (if one wants to keep the labels). Therefore, the Leibniz-Clarke correspondence cannot be explained as a clash between voluntarism and intellectualism. Published on 2022-02-18 12:23:56. (shrink)

The main aim of this article is to contribute to the discussion about the universality of well-being by juxtaposing the theoretical and empirical arguments of the two extreme theoretical positions regarding the possibility of a universal notion of well-being. The article first explains that the question about the possibility of a universal notion of well-being is ultimately a matter of the nature of well-being. While researchers who opt for the universalist position are convinced that their empirical data show that the (...) differences in the nature of well-being are minor enough that a universal notion is possible, the proponents of the culturalist position believe that their research uncovers more dramatic differences in the nature of well-being. Therefore, they reject a universal notion of well-being. By reading one position against the other on theoretical and empirical levels, the article illuminates and assesses the limitations, problems and possible dangers of both and considers which position regarding the possibility of a universal notion of well-being seems more convincing . The article concludes that currently the culturalist position seems more reasonable, as long as it remains open to a possible discovery of a more universal structure in the nature of well-being promised by the emerging field of neuroscience of happiness.

In the past, experts have disagreed about whether Samuel Clarke accepted the idea that gravity is a power superadded to matter by God. Most scholars now agree that Clarke did not support superaddition. But the argumentation employed by Clarke to reject superaddition has not been studied before in detail. In this paper, I explicate Clarke's argumentation by relating it to an important discussion about the possibility of superadded gravity in the Clarke-Collins correspondence. I examine Clarke's responses to Collins and draw (...) on his other works to reconstruct Clarke's reasons for rejecting superadded gravity. (shrink)

Many people living in highly industrialised countries and elsewhere emit greenhouse gases at a certain high level as a by-product of their activities, and they expect to be able to continue to emit at that level. This level is far above the just per capita level. We investigate whether that expectation is legitimate and permissible. We argue that the expectation is epistemically legitimate. Given certain assumptions, we can also think of it as politically legitimate. Also, the expectation is shown to (...) be morally permissible but with major qualifications. The interpretation of the significance of the expectation is compatible with the understanding that historical emissions should count in terms of fairly distributing the benefits of emission-generating activities over people’s lifetimes but constrains the way in which we may collectively respond to climate change.

Climate change can be interpreted as a unique case of historical injustice involving issues of both intergenerational and global justice. We split the issue into two separate questions. First, how should emission rights be distributed? Second, who should come up for the costs of coping with climate change? We regard the first question as being an issue of pure distributive justice and argue on prioritarian grounds that the developing world should receive higher per capita emission rights than the developed world. (...) This is justified by the fact that the latter already owns a larger share of benefits associated with emission generating activities because of its past record of industrialisation. The second question appears to be an issue of compensatory justice. After defining what we mean by compensation, we show that different kinds of compensatory principles run into problems when used to justify payments by historical emitters of the North to people suffering from climate change in the South. As an alternative, we propose to view payments from wealthy countries for adaptation to climate change in vulnerable countries rather as a measure based on concerns of global distributive justice.

In this paper, I explore a new approach to we-mode agency drawing on the concept of layered agency. I argue that agents can shut out their personal attitudes in favour of a perspective jointly established with other people. I can act as a member of the philosophy department aiming for what the department agreed on, even if that might conflict with my personal beliefs. I can shut out these personal beliefs for a moment and reason from the group’s standpoint. While (...) this observation itself is not novel, I provide an original account for this phenomenon building on C. Thi Nguyen’s proposal of layered agency. I then use this new account of the we-mode as a basic building block for conceptualising social groups and group attitudes. I end by showing how the proposal deals with common cases from the literature. (shrink)

ABSTRACT Stephen Gardiner’s A Perfect Moral Storm offers an in-depth analysis of the ethical facets of climate change. In this paper, I contend that he nonetheless overlooks an important structural layer to climate vulnerabilities and injustices because he analyzes them implicitly interactional. I argue that climate change should rather be understood as a form of structural injustice as outlined by Iris M. Young. In this reading, the unjust socio-economic structural processes that give rise to climate change, the production and consumption (...) of fossil fuel energy, are at their core marked by (i) oppressive and dominating power relations that position agents (ii) intersecting with other structural constraints. Crucially, (iii) these structural processes arose historically, persist over time, and entrench the burden on those suffering in the future. This viewpoint improves our understanding of how the climate crisis unfolds over time in a way that augments Gardiner’s analysis. The structural approach can advance the climate justice debate both theoretically and practically. (shrink)

Adding an option is a neglected mechanism for bringing about behavioural change. This mechanism is distinct from nudges, which are changes in the choice architecture, and instead makes it possible to pursue republican paternalism, a unique form of paternalism in which choices are changed by expanding people's set of options. I argue that this is truly a form of paternalism (albeit a relatively soft one) and illustrate some of its manifestations in public policy, specifically public options and market creation. Furthermore, (...) I compare it with libertarian paternalism on several dimensions, namely respect for individuals' agency, effectiveness, and efficiency. Finally, I consider whether policymakers have the necessary knowledge to successfully change behaviour by adding options. Given that adding an option has key advantages over nudges in most if not all of these dimensions, it should be considered indispensable in the behavioural policymaker's toolbox. (shrink)

The article takes the renewed popularity and interest in epidemiological modelling for Covid-19 as a point of departure to ask how modelling has historically shaped epidemiological reasoning. The focus lies on a particular model, developed in the late 1920s through a collaboration of the former field-epidemiologists and medical officer, Wade Hampton Frost, and the biostatistician and population ecologist Lowell Reed. Other than former approaches to epidemic theory in mathematical formula, the Reed-Frost epidemic theory was materialised in a simple mechanical analogue: (...) a box with coloured marbles and a wooden trough. The article reconstructs how the introduction of this mechanical model has reshaped epidemiological reasoning by shifting the field from purely descriptive to analytical practices. It was not incidental that the history of this model coincided with the foundation of epidemiology as an academic discipline, as it valorised and institutionalised new theoretical contributions to the field. Through its versatility, the model shifted the field’s focus from mono-causal explanations informed by bacteriology, eugenics or sanitary perspectives towards the systematic consideration of epidemics as a set of interdependent and dynamic variables.

The positive, non-exclusive inference of _only_ has been famously elusive with respect to its projective status and its content: in some cases the positive inference behaves like a presupposition, while in others it does not; in some cases the inference is non-modal, corresponding to the prejacent of _only_ or an existential counterpart of it, while in others it is modalized. This behavior, we argue, surfaces the exceptive nature of _only_ (cf. von Fintel and Iatridou in Linguist Inq 38(3):445–483, 2007). More (...) specifically, if the import of _only_ is distributed between a minimality and a subtraction component, as has been argued for exceptives (esp. Gajewski in Nat Lang Semant 16(1):69–110, 2008), the apparently irreconcilable properties of _only_ can be captured. (shrink)

Hybrid contingentism combines first-order contingentism, the view that it is contingent what individuals there are, with higher-order necessitism, the view that it is non-contingent what properties and propositions there are (where these are conceived as entities in the range of appropriate higher-order quantifiers). This combination of views avoids the most delicate problems afflicting alternative contingentist positions while preserving the central contingentist claim that ordinary, concrete entities exist contingently. Despite these attractive features, hybrid contingentism is usually faced with rejection. The main (...) reason for this is an objection that crucially involves haecceitistic properties, properties such as being identical to Plato or being identical to Aristotle. The objection alleges that by accepting the necessary existence of such haecceities, hybrid contingentists incur an explanatory commitment that they are unable to discharge, namely that of explaining how it is that certain haecceities ‘lock onto’ their target individuals even when those individuals are absent. To defend hybrid contingentism against this charge, I first clarify the haecceities objection in several respects and consider, in particular, what notion of explanation the objection is operating with. After arguing that it can be fruitfully understood as a challenge to provide metaphysical grounds for certain haecceity facts, I develop a contingentist response to the objection that draws on recent work on the connection between ground and essence.
