The ecosystem services argument is a highly publicised instrumental argument for protecting biodiversity. I develop a new objection to this argument based on the lack of a causal connection from global species losses to local ecosystem changes. I survey some alternative formulations of services arguments, including ones incorporating option value or a precautionary principle, and show that they do not fare much better than the standard version. I conclude that environmental thinkers should rely less on ecosystem services as a means (...) to defend biodiversity, and that attention should be focused on additional types of value which might be attributed to global biodiversity.

I develop an account of ecological role functions—the functions of species within ecosystems—which is informed by alternative regime phenomena in ecology. My account is a causal-role theory which includes a counterfactual sensitivity condition. The account tracks and explains a distinction ecologists make between functions and various activities which are not functions. My counterfactual sensitivity condition resolves the liberality problem often attributed to causal-role theories of function, while also illuminating the explanatory centrality of role functions within ecology.

This paper addresses the stalemate on the question whether biodiversity has intrinsic value. I distinguish between a “weak” conception and two “strong” conceptions of intrinsic value in the environmental ethics literature. The strong conceptions of intrinsic value are connected, respectively, to moral standing and to a strongly objectivist account of value. Neither of these forms of value likely applies to biodiversity. However, the weak conception of intrinsic value is neutral about both moral standing and the nature of value and plausibly (...) applies to biodiversity. In addition, weak intrinsic value avoids common objections to the claim that biodiversity is intrinsically valuable. I develop a cumulative argument showing that environmentalists should presume that biodiversity has intrinsic value in the weak sense. (shrink)

Ecological neutral theory has been controversial as an alternative to niche theory for explaining community structure. Neutral theory, which explains community structure in terms of ecological drift, is frequently charged with being unrealistic, but commentators have usually not provided an account of theory or model realism. In this paper, I propose a framework for comparing the “realism” or accuracy of alternative theories within a domain with respect to the extent to which the theories abstract and idealize. Using this framework I (...) argue, contrary to most previous commentators, that neutral and niche theories are similarly realistic. Realism cannot provide a basis for accepting or rejecting either type of theory; instead, community ecologists should continue working with a plurality of models. While theoretical unification may become possible, we should treat a plurality of complementary, partial models as the expected situation within community ecology. (shrink)

We characterize four fruitful and underappreciated epistemic roles played by the concept of an individualized niche in contemporary biology, utilizing results of a qualitative empirical study conducted within an interdisciplinary biological research center. We argue that the individualized niche concept (1) shapes the research agenda of the center, (2) facilitates explaining core phenomena related to inter-individual differences, (3) helps with managing individual-level causal complexity, and (4) promotes integrating local knowledge from ecology, evolutionary biology, behavioral biology and other biological fields. We (...) thereby also challenge arguments that the niche concept is superfluous in ecology. (shrink)

The main aim of this book is to introduce the topic of limited awareness, and changes in awareness, to those interested in the philosophy of decision-making and uncertain reasoning.

The Bayesian maxim for rational learning could be described as conservative change from one probabilistic belief or credence function to another in response to newinformation. Roughly: ‘Hold fixed any credences that are not directly affected by the learning experience.’ This is precisely articulated for the case when we learn that some proposition that we had previously entertained is indeed true (the rule of conditionalisation). But can this conservative-change maxim be extended to revising one’s credences in response to entertaining propositions or (...) concepts of which one was previously unaware? The economists Karni and Vierø (2013, 2015) make a proposal in this spirit. Philosophers have adopted effectively the same rule: revision in response to growing awareness should not affect the relative probabilities of propositions in one’s ‘old’ epistemic state. The rule is compelling, but only under the assumptions that its advocates introduce. It is not a general requirement of rationality, or so we argue. We provide informal counterexamples. And we show that, when awareness grows, the boundary between one’s ‘old’ and ‘new’ epistemic commitments is blurred. Accordingly, there is no general notion of conservative change in this setting. (shrink)

Laurie Paul argues that, when it comes to many of your most significant life-changing decisions, the principles of rational choice are silent. That is because, in these cases, you anticipate that one of your choice options would yield a transformative experience. We argue that such decisions are best seen as ones in which you anticipate awareness growth. You do not merely lack knowledge about which possible outcome will arise from a transformative option; you lack knowledge about what are the possible (...) outcomes. We show how principles of rational choice can be extended to cases of anticipated awareness growth. (shrink)

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

Katie Steele and H. Orri Stefánsson argue that, to reflect an agent’s limited awareness, the algebra of propositions on which that agent’s credences are defined should be relativised to their awareness state. I argue that this produces insurmountable difficulties. But the project of relativising the agent’s algebra to reflect their partial perspective need not be abandoned: the algebra can be relativised, not to the agent’s awareness state, but to what we might call their subjective modality.

Recent critics (Andrew Light, Bryan Norton, Anthony Weston, and Bruce Morito, among others) have argued that we should give up talk of intrinsic value in general and that of nature in particular. While earlier theorists might have overestimated the importance of intrinsic value, these recent critics underestimate its importance. Claims about a thing’s intrinsic value are claims about the distinctive way in which we have reason to care about that thing. If we understand intrinsic value in this manner, we can (...) capture the core claims that environmentalists want to make about nature while avoiding the worries raised by contemporary critics. Since the distinction between intrinsic and extrinsic value plays a critical role in our understanding of the different ways that we do and should care about things, moral psychology, ethical theory in general, and environmental ethics in particular shouldn’t give up on the concept of intrinsic value.

Most ethicists agree that at least some nonhumans have interests that are of direct moral importance. Yet with very few exceptions, both climate ethics and climate policy have operated as though only human interests should be considered in formulating and evaluating climate policy. In this paper I argue that the anthropocentrism of current climate ethics and policy cannot be justified. I first describe the ethical claims upon which my analysis rests, arguing that they are no longer controversial within contemporary ethics. (...) Next, I review work in climate ethics and policy, demonstrating the absence of consideration of nonhuman interests in both domains. Finally, I consider five possible justifications for omitting nonhuman interests in the evaluation climate policy options, arguing that none of these arguments succeeds. (shrink)

This article is about the special, subjective concepts we apply to experience, called “phenomenal concepts”. They are of special interest in a number of ways. First, they refer to phenomenal experiences, and the qualitative character of those experiences whose metaphysical status is hotly debated. Conscious experience strike many philosophers as philosophically problematic and difficult to accommodate within a physicalistic metaphysics. Second, PCs are widely thought to be special and unique among concepts. The sense that there is something special about PCs (...) is very closely tied up with features of the epistemic access they afford to qualia. When we deploy phenomenal concepts introspectively to some phenomenally conscious experience as it occurs, we are said to be acquainted with our own conscious experiences. Accounts of PCs either have to explain the acquaintance relation, or acquaintance with our phenomenal experiences has to be denied. PCs have received much attention in recent philosophy of mind mainly because they figure in arguments for dualism and in physicalist responses to these arguments. The main topic of this paper is to explore different accounts of phenomenal concepts and their role in recent debates over the metaphysical status of phenomenal consciousness. (shrink)

We argue that concerns about double-counting—using the same evidence both to calibrate or tune climate models and also to confirm or verify that the models are adequate—deserve more careful scrutiny in climate modelling circles. It is widely held that double-counting is bad and that separate data must be used for calibration and confirmation. We show that this is far from obviously true, and that climate scientists may be confusing their targets. Our analysis turns on a Bayesian/relative-likelihood approach to incremental confirmation. (...) According to this approach, double-counting is entirely proper. We go on to discuss plausible difficulties with calibrating climate models, and we distinguish more and less ambitious notions of confirmation. Strong claims of confirmation may not, in many cases, be warranted, but it would be a mistake to regard double-counting as the culprit. 1 Introduction2 Remarks about Models and Adequacy-for-Purpose3 Evidence for Calibration Can Also Yield Comparative Confirmation3.1 Double-counting I3.2 Double-counting II4 Climate Science Examples: Comparative Confirmation in Practice4.1 Confirmation due to better and worse best fits4.2 Confirmation due to more and less plausible forcings values5 Old Evidence6 Doubts about the Relevance of Past Data7 Non-comparative Confirmation and Catch-Alls8 Climate Science Example: Non-comparative Confirmation and Catch-Alls in Practice9 Concluding Remarks.

In this paper, we develop a novel response to counterfactual scepticism, the thesis that most ordinary counterfactual claims are false. In the process we aim to shed light on the relationship between debates in the philosophy of science and debates concerning the semantics and pragmatics of counterfactuals. We argue that science is concerned with many domains of inquiry, each with its own characteristic entities and regularities; moreover, statements of scientific law often include an implicit ceteris paribus clause that restricts the (...) scope of the associated regularity to circumstances that are ‘fitting’ to the domain in question. This observation reveals a way of responding to scepticism while, at the same time, doing justice both to the role of counterfactuals in science and to the complexities inherent in ordinary counterfactual discourse and reasoning.

While holist views such as ecocentrism have considerable intuitive appeal, arguing for the moral considerability of ecological wholes such as ecosystems has turned out to be a very difficult task. In the environmental ethics literature, individualist biocentrists have persuasively argued that individual organisms—but not ecological wholes—are properly regarded as having a good of their own . In this paper, I revisit those arguments and contend that they are fatally flawed. The paper proceeds in five parts. First, I consider some problems (...) brought about by climate change for environmental conservation strategies and argue that these problems give us good pragmatic reasons to want a better account of the welfare of ecological wholes. Second, I describe the theoretical assumptions from normative ethics that form the background of the arguments against holism. Third, I review the arguments given by individualist biocentrists in favour of individualism over holism. Fourth, I review recent work in the philosophy of biology on the units of selection problem, work in medicine on the human biome, and work in evolutionary biology on epigenetics and endogenous viral elements. I show how these developments undermine both the individualist arguments described above as well as the distinction between individuals and wholes as it has been understood by individualists. Finally, I consider five possible theoretical responses to these problems. (shrink)

Resentment, as it is currently understood in the philosophical literature, is individual. That is, it is anger about a moral injury done to oneself. But in some cases, resentment responds to systemic harms and injustices rather than direct moral injuries. The purpose of this paper is to move beyond individualistic conceptions of resentment to develop an account of collective resentment that better captures the character and effects of the emotion in these cases. I use the example of indigenous and settler (...) Canadians’ reciprocal resentments in response to the Indian Residential Schools and continuing political disagreements as an example of a context in which understanding collective resentment is important.

This paper defends an account of moral shock as an emotional response to intensely bewildering events that are also of moral significance. This theory stands in contrast to the common view that shock is a form of intense surprise. On the standard model of surprise, surprise is an emotional response to events that violated one's expectations. But I show that we can be morally shocked by events that confirm our expectations. What makes an event shocking is not that it violated (...) one's expectations, but that the content of the event is intensely bewildering. What causes moral shock is, I argue, our lack of emotional preparedness for the event. And I show that, despite the relative lack of attention to shock in the philosophical literature, the emotion is significant to moral, social, and political life. (shrink)

Neosentimentalist accounts of value need an explanation of which of the sentiments they discuss are pro-attitudes, which attitudes are con-attitudes, and why. I argue that this project has long been neglected in the philosophical literature, even by those who make extensive use of the distinction between pro- and con-attitudes. Using the attitudes of awe and respect as exemplars, I argue that it is not at all clear what if anything makes these attitudes pro-attitudes. I conclude that neither our intuitive sense (...) of the distinction nor the vague accounts of it that exist in the philosophical literature are especially helpful in sorting out the hard cases. What is needed is a more explicit and thorough account of what the valence of our attitudes consists in. (shrink)

This article defends an account of collective hope that arises through solidarity in the pursuit of justice. I begin by reviewing recent literature on the nature of hope. I then explore the relationship between hope and solidarity to demonstrate the ways in which solidarity can give rise to hope. I suggest that the hope born of solidarity is collective when it is shared by at least some others, when it is caused or strengthened by activity in a collective action setting, (...) and when the reciprocal hopeful expressions of individual group members result in an emotional atmosphere of hope that extends across the group. In the context of social movements, collective hope emerges alongside the collective intentions and actions of the solidarity group; namely, in the pursuit of a form of social justice that inspires the movement. I then suggest that the object of collective hope born of solidarity is the guiding ideal of justice and reflect on what it might mean to hope well for justice. (shrink)

This article argues that common intuitions regarding (a) the specialness of ‘use-novel’ data for confirmation and (b) that this specialness implies the ‘no-double-counting rule’, which says that data used in ‘constructing’ (calibrating) a model cannot also play a role in confirming the model’s predictions, are too crude. The intuitions in question are pertinent in all the sciences, but we appeal to a climate science case study to illustrate what is at stake. Our strategy is to analyse the intuitive claims in (...) light of prominent accounts of confirmation of model predictions. We show that on the Bayesian account of confirmation, and also on the standard classical hypothesis-testing account, claims (a) and (b) are not generally true; but for some select cases, it is possible to distinguish data used for calibration from use-novel data, where only the latter confirm. The more specialized classical model-selection methods, on the other hand, uphold a nuanced version of claim (a), but this comes apart from (b), which must be rejected in favour of a more refined account of the relationship between calibration and confirmation. Thus, depending on the framework of confirmation, either the scope or the simplicity of the intuitive position must be revised. (shrink)

Philosophers have started to theorize the concept of ‘affective injustice’ to make sense of certain ways in which people’s affective lives are significantly marked by injustice. This new research has offered important insights into people’s lived experiences under oppression. But it is not immediately clear how the concept ‘affective injustice’ picks out something different from the closely related phenomenon of ‘psychological oppression.’ This paper considers the question of why we might need new theories of affective injustice in light of the (...) well-established cross-disciplinary literature on psychological oppression. I suggest that, whereas psychological oppression is found in the hearts and minds of people who are oppressed, affective injustice is most fruitfully understood as a structural phenomenon. It operates primarily outside of us: in affective norms, practices, and relationships that are embedded in social conditions of injustice. The account I offer is tentative and incomplete. But my hope is that it will help show how theorizing affective injustice has the potential to enrich existing theories of justice and theories of psychological oppression. (shrink)

In engineering, as in other scientific fields, researchers seek to confirm their models with real-world data. It is common practice to assess models in terms of the distance between the model outputs and the corresponding experimental observations. An important question that arises is whether the model should then be ‘tuned’, in the sense of estimating the values of free parameters to get a better fit with the data, and furthermore whether the tuned model can be confirmed with the same data (...) used to tune it. This dual use of data is often disparagingly referred to as ‘double-counting’. Here, we analyse these issues, with reference to selected research articles in engineering. Our example studies illustrate more and less controversial practices of model tuning and double-counting, both of which, we argue, can be shown to be legitimate within a Bayesian framework. The question nonetheless remains as to whether the implied scientific assumptions in each case are apt from the engineering point of view. (shrink)

This chapter considers the possibility and ethics of collective forgiveness. I begin by distinguishing between different forms of forgiveness to illustrate what it might look like for a collective to forgive that is distinct from the individual and group-based forgiveness of its members. I then consider how emotional models of forgiveness might capture the phenomenon of collective forgiveness. I argue that shortcomings with emotional models suggest that performative and social practice models of forgiveness more plausibly extend to collective forgiveness. I (...) close by exploring a range of moral questions and objections to practices of collective forgiveness. (shrink)

This paper addresses the question of what the attitude of hope consists in. We argue that shortcomings in recent theories of hope have methodological roots in that they proceed with little regard for the rich body of literature on the emotions. Taking insights from work in the philosophy of emotions, we argue that hope involves a kind of normative perception. We then develop a strategy for determining the content of this perception, arguing that hope is a perception of practical reasons. (...) Our proposal stands in contrast with familiar views on which hope is fundamentally about the good. We conclude by considering the increasingly popular idea that some hopes are non-intentional and thus, by implication, non-perceptual. We reply by arguing that our perceptual theory plausibly generalizes to these instances of hope. (shrink)

In this essay, we suggest practical ways to shift the framing of crisis standards of care toward disability justice. We elaborate on the vision statement provided in the 2010 Institute of Medicine (National Academy of Medicine) “Summary of Guidance for Establishing Crisis Standards of Care for Use in Disaster Situations,” which emphasizes fairness; equitable processes; community and provider engagement, education, and communication; and the rule of law. We argue that interpreting these elements through disability justice entails a commitment to both (...) distributive and recognitive justice. The disability rights movement's demand “Nothing about us, without us” requires substantive inclusion of disabled people in decision‐making related to their interests, including in crisis planning before, during, and after a pandemic like Covid‐19.

Polarization poses a critical threat to the stability of nations around the world, as it impacts climate change, populism, democracy, and global health. This perspective examines the conceptual understanding, measurement challenges, and potential interventions for polarization. Our analysis highlights the distinction and interactions between the individual and collective levels of polarization, conceptually, methodologically, and in terms of interventions. We conclude by pointing out future directions for understanding polarization and highlighting the interrelations between polarization and other social phenomena. -/- .

The spreading of false information on social media platforms is becoming increasingly common and thus, is creating an epistemic environment where people don’t know what to believe. Within this essay, I will argue that measures should be taken to address and reduce the spreading of false information on social media platforms, furthermore, accountability mechanisms should be implicated in order to do so.

This chapter reports on Sweden as an active and critical player within the European sharing economy. With a key focus on cities, Sweden has launched a national program, “Sharing Cities Sweden”—a strategic innovation program for smart and sustainable cities with an allocated budget of 12 million EUR over four years. The objectives of the program are to develop world-leading test-beds for the sharing economy in Stockholm, Gothenburg, Malmö, and Umeå, as well as develop a national node to significantly improve national (...) and international cooperation and promote an exchange of experience on sharing cities. In the following pages, the sharing economy in Sweden is outlined, first, through exploring the definitions adopted by various actors and key questions to be addressed, and second, with the help of examples of existing collaborative economy platforms. The report concludes with a discussion on the collaborative economy in a Swedish context, forthcoming developments in the sector, and the associated issues and challenges. (shrink)

Philip's interest is specifically aimed toward the ethics of Transhumanism and depictions of Transhumanism in works of fiction.

While the two perspectives might not seem that close, there is certain to be an overlap in Andrew and Philip's shared understanding of how technological phenomena play a crucial role (...) concerning religion and society.

Since Case and Deaton (2015) coined the term ‘deaths of despair,’ there has been significant empirical work and public interest in the topic. Yet social scientists studying this topic lament the absence of a clear theory of despair. Philosophical inquiry into the nature and value of hope has begun to fill this gap, with despair often cited as the opposite of hope. The assumption that hope and despair are opposites has helped to motivate two central tasks in the literature: how (...) a theory of hope can make sense of the difference between hope and despair, and how hope might prevent people from falling into despair. Yet the focus of inquiry has been principally on hope. This paper builds on the existing literature to offer a theory of despair. We argue that despair is a mode of sadness whereby one experiences the loss of reasons to take seriously that which one desires. Our account of despair captures a set of desiderata that any theory of despair should explain, and it offers useful conceptual resources to social scientists studying deaths of despair. (shrink)

Many philosophers of science are ontologically committed to a lush rainforest of special science entities ), but are often reticent about the criteria that determine which entities count as real. On the other hand, the metaphysics literature is much more forthcoming about such criteria, but often links ontological commitment to irreducibility. We argue that the irreducibility criteria are in tension with scientific realism: for example, they would exclude viruses, which are plausibly theoretically reducible and yet play a sufficiently important role (...) in scientific accounts of the world that they should be included in our ontology. In this paper, we show how the inhabitants of the rainforest can be inoculated against the eliminative threat of reduction: by demonstrating that they are emergent. According to our account, emergence involves a screening off condition as well as novelty. We go on to demonstrate that this account of emergence, which is compatible with theoretical reducibility, satisfies common intuitions concerning what should and shouldn't count as real: viruses are emergent, as are trouts and turkeys, but philosophically gerrymandered objects like trout-turkeys do not qualify.

In the biomedical context, policy makers face a large amount of potentially discordant evidence from different sources. This prompts the question of how this evidence should be aggregated in the interests of best-informed policy recommendations. The starting point of our discussion is Hunter and Williams’ recent work on an automated aggregation method for medical evidence. Our negative claim is that it is far from clear what the relevant criteria for evaluating an evidence aggregator of this sort are. What is the (...) appropriate balance between explicitly coded algorithms and implicit reasoning involved, for instance, in the packaging of input evidence? In short: What is the optimal degree of ‘automation’? On the positive side: We propose the ability to perform an adequate robustness analysis as the focal criterion, primarily because it directs efforts to what is most important, namely, the structure of the algorithm and the appropriate extent of automation. Moreover, where there are resource constraints on the aggregation process, one must also consider what balance between volume of evidence and accuracy in the treatment of individual evidence best facilitates inference. There is no prerogative to aggregate the total evidence available if this would in fact reduce overall accuracy. (shrink)

Brouwer’s intuitionism was a far-reaching attempt to reform the foundations of mathematics. While the mathematical community was reluctant to accept Brouwer’s work, its response to later-developed brands of intuitionism, such as those presented by Hermann Weyl and Arend Heyting, was different. The paper accounts for this difference by analyzing the intuitionistic versions of Brouwer, Weyl, and Heyting in light of a two-tiered model of the body and image of mathematical knowledge. Such a perspective provides a richer account of each story (...) and points to a possible connection between the community’s reaction and the changes each mathematician had proposed. (shrink)

Heyes presents a compelling account of how cultural evolutionary processes shape and create “rules,” or norms, of social behavior. She suggested that normativity depends on implicit, genetically inherited, domain-general processes and explicit, culturally inherited, domain-specific processes. Her approach challenges the nativist point of view and provides supporting evidence that shows how social interactions are responsible for creating mental processes that assist in understanding and behaving according to rules or norms. We agree. In our commentary, we suggest that it is not (...) only that mental processes for grasping norms are recreated in each generation but also that social interactions shape the kinds of social groups that are recognized (for a more extensive discussion, see Kish Bar-On & Lamm, 2023). We highlight evidence showing that accounts of norm psychology thus require a richer notion of human groups. (shrink)

These results illustrate the difficulty in making the PP consistent with the acceptance of any trade-offs between catastrophic risks (...) and more ordinary goods. (shrink)

ABSTRACT Offsetting is a very ineffective way to do good. Offsetting your lifetime emissions may increase aggregated life expectancy by at most seven years, while giving the amount it costs to offset your lifetime emissions to a malaria charity saves in expectation the life of at least one child. Is there any moral reason to offset rather than giving to some charity that does good so much more effectively? There might be such a reason if your offsetting compensated or somehow (...) benefitted the victims of your emission, since that could mean that you would satisfy the duty not to harm others by emitting and offsetting. But that is typically not true. If your emission harms some person and your offsetting benefits some person, then these are most likely different people. Hence, I conclude, we have a stronger reason to give to effective charities than we have to offset our emissions. (shrink)

Society is a composite of interacting people and groups. These groups play a significant role in maintaining social status, establishing group identity and social identity, and enforcing norms. As such, groups are essential for understanding human behavior. Nevertheless, the study of groups in everyday group life yields many diverse and sometimes contradicting theories of group behavior, and researchers tend to agree that we have yet to understand the emergence of groups out of aggregates of individuals. The current paper aims to (...) shed new light on the convoluted interrelation between groups and individuals by focusing on individuals’ social identities and group categorization. It does so by exploring the dynamic nature of the self and its implications on identity and group membership, and introducing a framework recognizing the fluidity of groups and group categorization. Incorporating historical insights with contemporary theories, this paper argues for a flexible understanding of group dynamics that surpasses rigid in-group and out-group classifications, proposing instead that group affiliations exist along a continuum that reflects the ever-changing social landscape.

The veil of ignorance argument was used by John C. Harsanyi to defend Utilitarianism and by John Rawls to defend the absolute priority of the worst off. In a recent paper, Lara Buchak revives the veil of ignorance argument, and uses it to defend an intermediate position between Harsanyi's and Rawls' that she calls Relative Prioritarianism. None of these authors explore the implications of allowing that agent's behind the veil are averse to ambiguity. Allowing for aversion to ambiguity---which is both (...) the most commonly observed and a seemingly reasonable attitude to ambiguity---however supports a version of Egalitarianism, whose logical form is quite different from the theories defended by the aforementioned authors. Moreover, it turns out that the veil of ignorance argument neither supports standard Utilitarianism nor Prioritarianism unless we assume that rational people are insensitive to ambiguity. (shrink)

Part of a book symposium for Peter Langland-Hassan's Explaining Imagination (2020).

Brouwer's philosophy of mathematics is usually regarded as an intra-subjective, even solipsistic approach, an approach that also underlies his mathematical intuitionism, as he strived to create a mathematics that develops out of something inner and a-linguistic. Thus, points of connection between Brouwer's mathematical views and his views about and the social world seem improbable and are rarely mentioned in the literature. The current paper aims to challenge and change that. The paper employs a socially oriented prism to examine Brouwer's views (...) on the construction, use, and practice of mathematics. It focuses on Brouwer's views on language, his social interactions, and the importance of group context as they appear in the significs dialogues. It does so by exploring the establishment and dissolution of the significs movement, focusing on Gerrit Mannoury's influence and relationship with Brouwer and analyzing several fragments from the significs dialogues while emphasizing the role Brouwer ascribed to groups in forming and sharing new ideas. The paper concludes by raising two questions that challenge common historical and philosophical readings of intuitionism. (shrink)

I defend a weak version of the Pigou-Dalton principle for chances. The principle says that it is better to increase the survival chance of a person who is more likely to die rather than a person who is less likely to die, assuming that the two people do not differ in any other morally relevant respect. The principle justifies plausible moral judgements that standard ex post views, such as prioritarianism and rank-dependent egalitarianism, cannot accommodate. However, the principle can be justified (...) by the same reasoning that has recently been used to defend the core axiom of ex post prioritarianism and egalitarianism, namely, Pigou-Dalton for well-being. The arguably biggest challenge for proponents of Pigou-Dalton for chances is that it violates State Dominance for social prospects. However, I argue that we have independent reason for rejecting State Dominance for social prospects, since it prevents a social planner from properly respecting people's preferences. (shrink)

Ingenieur- und Naturwissenschaften sind Knoten eines engen Beziehungsgeflechts, in dem Mensch und Gesellschaft, Natur und Kultur weitere Knoten sind. Entwicklungen in diesen beiden Bereichen haben somit stets Auswirkungen sowohl auf die anderen Knoten als auf das Beziehungsgeflecht als Ganzes.

Bartha and DesRoches (2021) and Steel and Bartha (2023) argue that we should understand the precautionary principle as the injunction to maximise lexical utilities. They show that the lexical utility model has important pragmatic advantages. Moreover, the model has the theoretical advantage of satisfying all axioms of expected utility theory except continuity. In this paper I raise a trilemma for any attempt at modelling the precautionary principle with lexical utilities: it permits choice cycles or leads to paralysis or implies that (...) the smallest value difference that is possible in a context has extreme axiological implications.
