ABSTRACT The rise of social media has correlated with an increase in political polarization, which many perceive as a threat to public discourse and democratic governance. This paper presents a framework, drawing on social epistemology and the economic theory of public goods, to explain how social media can contribute to polarization, making us collectively poorer, even while it provides a preferable media experience for individual consumers. Collective knowledge and consensus is best served by having richly connected networks that are epistemically (...) integrated: individuals with diverse levels of expertise should be relatively well connected to each other. In epistemically segregated networks, by contrast, we have reason to predict collective epistemic failures. Expert knowledge will be isolated from the majority, leading average opinion to be less informed than is socially optimal, and entrenching disagreements. Because social media enables users to very easily adopt homophilous network connections – connections to those with similar opinions, education levels, and social backgrounds – it is likely to have increased epistemic segregation compared to older media platforms. The paper explains the theoretical foundations of these predictions, and sketches regulatory measures – such as taxes – that might be employed to preserve the public good of a well integrated social media network.

If A is better than B and B is better than C, then A is better than C, right? Larry Temkin and Stuart Rachels say: No! Betterness is nontransitive, they claim. In this paper, I discuss the central type of argument advanced by Temkin and Rachels for this radical idea, and argue that, given this view very likely has sceptical implications for practical reason, we would do well to identify alternative responses. I propose one such response, which employs the idea (...) that rational agents might regard some options as incommensurate in value, and will reasonably employ a heuristic of status quo maintenance to avoid suboptimal choices from incommensurate goods.

This paper presents an attempt to integrate theories of causal processes—of the kind developed by Wesley Salmon and Phil Dowe—into a theory of causal models using Bayesian networks. We suggest that arcs in causal models must correspond to possible causal processes. Moreover, we suggest that when processes are rendered physically impossible by what occurs on distinct paths, the original model must be restricted by removing the relevant arc. These two techniques suffice to explain cases of late preëmption and other cases (...) that have proved problematic for causal models. (shrink)

Humean metaphysics is characterized by a rejection of necessary connections between distinct existences. Dispositionalists claim that there are basic causal powers. The existence of such properties is widely held to be incompatible with the Humean rejection of necessary connections. In this paper I present a novel theory of causal powers that vindicates the dispositionalist claim that causal powers are basic, without embracing brute necessary connections. The key assumptions of the theory are that there are natural types of causal processes, and (...) that manifestations of powers are identified with certain kinds of causal processes. From these assumptions, the modal features of powers are explained in terms of internal relations between powers themselves and the process-types in which powers are manifested. (shrink)

This paper develops two ideas with respect to dispositional properties: (1) Adapting a suggestion of Sungho Choi, it appears the conceptual distinction between dispositional and categorical properties can be drawn in terms of susceptibility to finks and antidotes. Dispositional, but not categorical properties, are not susceptible to intrinsic finks, nor are they remediable by intrinsic antidotes. (2) If correct, this suggests the possibility that some dispositions—those which lack any causal basis—may be insusceptible to any fink or antidote. Since finks and (...) antidotes are a major obstacle to a conditional analysis of dispositions, these dispositions that are unfinkable may be successfully analysed by the conditional analysis of dispositions. This result is of importance for those who think that the fundamental properties might be dispositions which lack any distinct causal basis, because it suggests that these properties, if they exist, can be analysed by simple conditionals and that they will not be subject to ceteris paribus laws. (shrink)

This paper discusses the prospects of a dispositional solution to the Kripke–Wittgenstein rule-following puzzle. Recent attempts to employ dispositional approaches to this puzzle have appealed to the ideas of finks and antidotes—interfering dispositions and conditions—to explain why the rule-following disposition is not always manifested. We argue that this approach fails: agents cannot be supposed to have straightforward dispositions to follow a rule which are in some fashion masked by other, contrary dispositions of the agent, because in all cases, at least (...) some of the interfering dispositions are both relatively permanent and intrinsic to the agent. The presence of these intrinsic and relatively permanent states renders the ascription of a rule-following disposition to the agent false. (shrink)

This paper examines the idea that there might be natural kinds of causal processes, with characteristic diachronic structure, in much the same way that various chemical elements form natural kinds, with characteristic synchronic structure. This claim -- if compatible with empirical science -- has the potential to shed light on a metaphysics of essentially dispositional properties, championed by writers such as Bird and Ellis.

Sacred value attitudes involve a distinctive profile of norm psychology: an absolutist prohibition on transgressing the value, combined with outrage at even hypothetical transgressions. This article considers three mechanisms by which such attitudes may be adaptive, and relates them to central theories regarding the evolution of religion. The first, “deterrence” mechanism functions to dissuade coercive expropriation of valuable resources. This mechanism explains the existence of sacred value attitudes prior to the development of religion and also explains analogues of sacred value (...) in non-human species. The two remaining mechanisms, “assurance” and “coalitional,” are more likely to have been involved in the cultural evolution of specifically religious behavior. In the assurance mechanism, sacred value attitudes increase the cost of ideological commitments, making them more reliable as signals of a cooperative disposition. In the coalitional mechanism, sacred value attitudes make it dangerous for third parties to dissent from a social norm, and thus discourage competitor ideologies. While both these mechanisms are compatible with major accounts of the evolution of religion, different theories suggest a greater or lesser emphasis on one mechanism or the other. (shrink)

David McCarthy has recently suggested that our compensation and liability practices may be interpreted as reflecting a fundamental norm to hold people liable for imposing risk of harm on others. Independently, closely related ideas have been criticised by Stephen R. Perry and Arthur Ripstein as incompatible with central features of negligence law. We aim to show that these objections are unsuccessful against McCarthy’s Risk–liability theory, and that such an approach is a promising means both for understanding the moral basis of (...) liability for negligence and for reasoning about possible reforms of the institution of negligence law.

In this paper we present an account of practical rationality and weakness of will in terms of rational capacities. We show how our account rectifies various shortcomings in Michael Smith's related theory. In particular, our account is capable of accommodating cases of weak-willed behaviour that are not `akratic', or otherwise contrary to the agent's better judgement. Our account differs from Smith's primarily by incorporating resolve: a third rational capacity for resolute maintenance of one's intentions. We discuss further two ways to (...) explain the importance of resolve to practical rationality: one based on Richard Holton's recent work, and an alternative, non-consequentialist account. (shrink)

The essentially comparative conception of value entails that the value of a state of affairs does not depend solely upon features intrinsic to the state of affairs, but also upon extrinsic features, such as the set of feasible alternatives. It has been argued that this conception of value gives us reason to abandon the transitivity of the better than relation. This paper shows that the support for intransitivity derived from this conception of value is very limited. On its most plausible (...) interpretations, it merely provides a necessary, but not sufficient, condition for intransitivity. It is further argued that the essentially comparative conception of value appears to support a disjunctive conclusion: there is incommensurability of value or betterness is not transitive. Of these two alternatives, incommensurability is preferable, because it is far less threatening to our other axiological commitments. (shrink)

The most familiar philosophical conception of objective chance renders determinism incompatible with non-trivial chances. This conception – associated in particular with the work of David Lewis – is not a good fit with our use of the word ‘chance’ and its cognates in ordinary discourse. In this paper we show how a generalized framework for chance can reconcile determinism with non-trivial chances, and provide for a more charitable interpretation of ordinary chance-talk. According to our proposal, variation in an admissible ‘evidence (...) base’ generates a spectrum of different chance functions. Successive coarse-grainings of the evidence base generates a partial ordering of chance functions, with finer trumping coarser if known. We suggest that chance-attributions in ordinary discourse express different chance functions in different contexts, and we sketch a potential contextual mechanism for making particular chance functions salient. The mechanism involves the idea that admissible evidence is available evidence: propositions that could be known. A consequence is that attributions of objective chances inherit the relatively familiar context-sensitivity associated with the modal ‘could’. We show how this context-dependency undermines certain arguments for the incompatibility of chance with determinism. (shrink)

This article gives a general overview of recent metaphysical work on dispositional properties and causal relations. It serves as an introduction to the edited volume, Dispositions and Causes.

The human faculty of moral judgment is not well suited to address problems, like climate change, that are global in scope and remote in time. Advocates of ‘moral bioenhancement’ have proposed that we should investigate the use of medical technologies to make human beings more trusting and altruistic, and hence more willing to cooperate in efforts to mitigate the impacts of climate change. We survey recent accounts of the proximate and ultimate causes of human cooperation in order to assess the (...) prospects for bioenhancement. We identify a number of issues that are likely to be significant obstacles to effective bioenhancement, as well as areas for future research. (shrink)

Necessitarian accounts of the laws of nature meet an apparent difficulty: for them, counterlegal conditionals, despite appearing to be substantive, seem to come out as vacuous. I argue that the necessitarian may use the presuppositions of counterlegal discourse to explain this. If the typical presupposition that necessitarianism is false is made explicit in counterlegal utterances, we obtain sentences such as 'If it turns out that the laws of nature are contingent, then if the laws had been otherwise, then such and (...) such would have been the case', which are non-vacuous and very often true. This goes a long way towards resolving the difficulty for necessitarianism. (shrink)

We know that Homo sapiens will not exist forever. Given this, how should our species end? What are the reasons, if any, to delay our extinction? In this paper, I show that the pre-eminent reasons which favour prolonging the existence of the species are partial: they will arise from the particular attachments and projects of the final few generations. While there may also be impartial reasons to prolong the species, these reasons are liable, with time, to reverse their valence: we (...) can be reasonably confident that they will ultimately recommend hastening the demise of the species. Consequently, it is likely that our descendants will eventually face a difficult -- possibly tragic -- conflict, between partial duties that recommend living on, and an impartial duty to extinguish the species.

Marc Lange objects to scientific essentialists that they can give no better account of the counterfactual invariance of laws than Humeans. While conceding this point succeeds ad hominem against some essentialists, I show that it does not undermine essentialism in general. Moreover, Lange's alternative account of the relation between laws and counterfactuals is - with minor modification - compatible with essentialism.

Orthodox decision theory gives no advice to agents who hold two goods to be incommensurate in value because such agents will have incomplete preferences. According to standard treatments, rationality requires complete preferences, so such agents are irrational. Experience shows, however, that incomplete preferences are ubiquitous in ordinary life. In this paper, we aim to do two things: (1) show that there is a good case for revising decision theory so as to allow it to apply non-vacuously to agents with incomplete (...) preferences, and (2) to identify one substantive criterion that any such non-standard decision theory must obey. Our criterion, Competitiveness, is a weaker version of a dominance principle. Despite its modesty, Competitiveness is incompatible with prospectism, a recently developed decision theory for agents with incomplete preferences. We spend the final part of the paper showing why Competitiveness should be retained, and prospectism rejected. (shrink)

Is a Nozickian theory of rights compatible with a no-fault motor insurance scheme? I say, Yes. The argument turns on an explication of the basis on which a Nozickian justifies the prohibition of merely risky activities.

Nations are understood to have a right to go to war, not only in defense of individual rights, but in defense of their own political standing in a given territory. This paper argues that the political defensive privilege cannot be satisfactorily explained, either on liberal cosmopolitan grounds or on pluralistic grounds. In particular, it is argued that pluralistic accounts require giving implausibly strong weight to the value of political communities, overwhelming the standing of individuals. Liberal cosmopolitans, it is argued, underestimate (...) the difficulties in disentangling a state’s role in upholding or threatening individual interests from its role in providing the social context that shapes and determines those very interests. The paper proposes an alternative theory, “prosaic statism”, which shares the individualistic assumptions of liberal cosmopolitanism, but avoids a form of fundamentalism about human rights, and is therefore less likely to recommend humanitarian intervention in non-liberal states.

Peer Instruction is a simple and effective technique you can use to make lectures more interactive, more engaging, and more effective learning experiences. Although well known in science and mathematics, the technique appears to be little known in the humanities. In this paper, we explain how Peer Instruction can be applied in philosophy lectures. We report the results from our own experience of using Peer Instruction in undergraduate courses in philosophy, formal logic, and critical thinking. We have consistently found it (...) to be a highly effective method of improving the lecture experience for both students and the lecturer. (shrink)

This is a review of Toby Handfield's book, "A Philosophical Guide to Chance", that discusses Handfield's Debunking Argument against realist accounts of chance.

Climate change threatens to infringe the human rights of many. Taking an optimistic stance, climate engineering might reduce the extent to which such rights are infringed, but it might also bring about other rights infringements. This Forum, leading off the special issue on climate engineering governance, engages three scholars in a discussion of three core issues at the intersection of human rights and climate engineering. The Forum is divided into three sections, each authored by a different scholar and discussing a (...) distinct aspect of this relationship. First, Toby Svoboda gives an overarching view of three competing approaches to human rights, grounded in philosophy; then, Holly Jean Buck looks at lessons from how the climate migration conversation brings a human rights approach to a climate policy issue; and finally, Pablo Suarez illustrates how a humanitarian approach to climate engineering works with a human rights framework. The conclusion of the Forum draws together points of overlap across the three sections and suggests a path forward for policy and research on this topic. Together, the sections show that climate engineering, should it materialize, will pose novel human rights challenges, and may well force reconsideration of how human rights are applied as a guide to action.

Instances of epistemic injustice elicit resistance, anger, despair, frustration or cognate emotional responses from their victims. This sort of response to the epistemic injustices that accompanied historical systems of oppression such as colonialism, for example, is normal. However, if their victims have internalised these oppressive situations, we could get the counterintuitive response of appreciation. In this paper, I argue for the phenomenon of appreciative silencing to make sense of instances like this. This is a form of epistemic silencing that happens (...) when the accepted hegemonic intuitions of the oppressed are formed/influenced by the ideologies of the oppressors over time. Here, we have a resilient, oppressive and hegemonic epistemic system. Put together, it creates a variant of epistemic injustice and silencing that is obscure since its victims are neither resistant nor aware of the injustice they face but are appreciative. (shrink)

As we understand them, dispositions are relatively uncontroversial 'predicatory' properties had by objects disposed in certain ways. By contrast, powers are hypothetical 'ontic' properties posited in order to explain dispositional behaviour. Chapter 1 outlines this distinction in more detail. Chapter 2 offers a summary of the issues surrounding analysis of dispositions and various strategies in contemporary literature to address them, including one of our own. Chapter 3 describes some of the important questions facing the metaphysics of powers including why they're (...) worth positing, and how they might metaphysically explain laws of nature and modality.

The deliberative systems approach is a recent innovation within the tradition of deliberative democratic theory. It signals an important shift in focus from the political legitimacy produced within isolated and formal sites of deliberation (e.g., Parliament or deliberative mini-publics), to the legitimacy produced by a number of diverse interconnected sites. In this respect, the deliberative systems (DS) approach is better equipped to identify and address defects arising from the systemic influences of power and coercion. In this article, I examine one (...) of the least explored and least understood defects: the exclusion of non-speaking political actors generated by the uniform privileging of speech in all sites within a system. Using the examples of prefigurative protest, Indigenous refusal to deliberate, and the non-deliberative agency of disabled citizens, I argue that the DS approach allows theorists to better understand forms of domination related to the imposition of speech on those who are either unwilling or unable to speak.

As a response to climate change, geoengineering with solar radiation management has the potential to result in unjust harm. Potentially, this injustice could be ameliorated by providing compensation to victims of SRM. However, establishing a just SRM compensation system faces severe challenges. First, there is scientific uncertainty in detecting particular harmful impacts and causally attributing them to SRM. Second, there is ethical uncertainty regarding what principles should be used to determine responsibility and eligibility for compensation, as well as determining how (...) much compensation ought to be paid. Significant challenges loom for crafting a just SRM compensation system. (shrink)

Anthropogenic climate change poses some difficult ethical quandaries for non-anthropocentrists. While it is hard to deny that climate change is a substantial moral ill, many types of non-human organisms stand to benefit from climate change. Modelling studies provide evidence that net primary productivity (NPP) could be substantially boosted, both regionally and globally, as a result of warming from increased concentrations of greenhouse gases. The same holds for deployment of certain types of climate engineering, or large-scale, technological modifications of the global (...) environment in order to prevent or slow anthropogenic climate change. For example, solar radiation management with stratospheric aerosol injections could benefit plant life by promoting enhanced photosynthesis, increasing diffuse radiation, and reducing heat stress. This has a surprising implication: from some non-anthropocentric perspectives, certain scenarios of climate change and climate engineering might bring about morally better states of affairs when compared to emission-mitigation baselines.

A Kantian approach can establish that non-human natural entities are morally considerable and that humans have duties to them. This is surprising, because most environmental ethicists have either rejected or overlooked Kant when it comes to this issue. Inspired by an argument of Christine Korsgaard, I claim that both humans and non-humans have a natural good, which is whatever allows an entity to function well according to the kind of entity it is. I argue that humans are required to confer (...) normative value on the natural good of all entities that have a natural good. This is so because, as a matter of fact, humans confer normative value on their own natural good simply because it is a natural good, which commits humans to the position that any natural good deserves to have normative value conferred on it. Since non-human natural entities have a natural good, their natural good deserves to have normative value conferred on it as well, and this is sufficient to make non-human natural entities morally considerable such that humans have duties to them.

Settler colonialism is structured in part according to the principle of civilizational progress yet the roots of this doctrine are not well understood. Disparate ideas of progress and practices related to colonial dispossession and domination can be traced back to the Enlightenment, and as far back as ancient Greece, but there remain unexplored logics and continuities. I argue that civilizational progress and settler colonialism are structured according to the opposition between politics governed by reason or faith and the figure of (...) the child as sinful or bestial. Thus, it is not contingent, but rather necessary that justificatory frameworks of European empire and colonialism depict Indigenous peoples as children. To illustrate how the theoretical link between Indigenous peoples and children emerges not as a simple analogy, but rather, as the source of the premodern/modern and savage/civilized binaries, I trace the various historical iterations of the political/childhood opposition through the classical, medieval, enlightenment, and modern eras. I show how the model of civilizational progress from a premodern and savage state of childhood continues to serve as the model for settler colonial exclusion and domination of Indigenous peoples.

According to indirect duty views, human beings lack direct moral duties to non-human organisms, but our direct duties to ourselves and other humans give rise to indirect duties regarding non-humans. On the orthodox interpretation of Kant’s account of indirect duties, one should abstain from treating organisms in ways that render one more likely to violate direct duties to humans. This indirect duty view is subject to several damaging objections, such as that it misidentifies the moral reasons we have to treat (...) non-humans in certain ways and that it sanctions only weak obligations vis-à-vis organisms. I develop an alternative indirect duty view: given a direct duty to oneself to cultivate virtuous dispositions, one has an indirect duty to abstain from treating organisms in ways that erode one’s virtues or develop vices. I argue that this indirect duty view strictly proscribes knowingly causing unnecessary harm to organisms, and I show that it is not subject to the damaging objections directed against the indirect duty view attributed to Kant by the orthodox interpretation. This suggests that indirect duty views are more worthy of consideration than is often supposed. (shrink)

Charles Sanders Peirce offers a number of arguments against the rational application of theory to morality, suggesting instead that morality should be grounded in instinct. Peirce maintains that we currently lack the scientific knowledge that would justify a rational structuring of morality. This being the case, philosophically generated moralities cannot be otherwise than dogmatic and dangerous. In this paper, I contend that Peirce’s critique of what I call “dogmatic-philosophical morality” should be taken very seriously, but I also claim that the (...) purely instinctive morality Peirce endorses is liable to a danger of its own, namely fanaticism. Indeed, Peirce himself recognizes this danger. As an alternative, I sketch a form of “pragmatic morality” that attempts to sidestep the dogmatism of philosophical morality and the fanaticism of instinctive morality. This form of morality avoids philosophical dogmatism by treating extant instincts as the postulates and materials with which it works. It avoids instinctive fanaticism by allowing a role to reason. By exhibiting fallibilism, revisability, pluralism, and meliorism, this type of reasoning can avoid the dogmatism of the philosophical kind of morality Peirce critiques. (shrink)

Climate engineering with stratospheric sulfate aerosol injections (SSAI) has the potential to reduce risks of injustice related to anthropogenic emissions of greenhouse gases. Relying on evidence from modeling studies, this paper makes the case that SSAI could have the potential to reduce many of the key physical risks of climate change identified by the Intergovernmental Panel on Climate Change. Such risks carry potential injustice because they are often imposed on low-emitters who do not benefit from climate change. Because SSAI has (...) the potential to reduce those risks, it thereby has the potential to reduce the injustice associated with anthropogenic emissions. While acknowledging important caveats, including uncertainty in modeling studies and the potential for SSAI to carry its own risks of injustice, the paper argues that there is a strong case for continued research into SSAI, especially if attention is paid to how it might be used to reduce emissions-driven injustice.

This paper begins with a discussion of Foucault's examination of Seneca's epistles in his late essay, "Self Writing." I argue that Foucault offers an accurate and interesting account of the practices Seneca employs in his epistles pursuant to his art of living. This paper then considers Foucault's interpretation of Seneca's art of living as an aesthetics of existence. I argue that this interpretation is unsatisfactory, instead suggesting that Seneca's art of living is a plausible response to the problem of suffering. (...) I close by arguing that such a conception of Seneca's art of living makes it relevant for present-day human beings, who, like Seneca, are subject to the problem of suffering. (shrink)

The binary between the figure of the child and the fully human being is invoked with regularity in analyses of race, yet its centrality to the conception of race has never been fully explored. For most commentators, the figure of the child operates as a metaphoric or rhetorical trope, a non-essential strategic tool in the perpetuation of White supremacy. As I show in the following, the child/human binary does not present a contingent or merely rhetorical construction but, rather, a central (...) feature of racialization. Where Black peoples are situated as objects of violence it is often precisely because Blackness has been identified with childhood and childhood is historically identified as the archetypal site of naturalized violence and servitude. I proceed by offering a historical account of how Black peoples came to inherit the subordination and dehumanization of European childhood and how White youth were subsequently spared through their partial categorization as adults.

As a site of colonial conquest, sub-Saharan Africa has experienced colonialism’s historic and continuing harms. One of the aspects of this harm is epistemic. In the analytic philosophical tradition, this harm can partly be theorised in line with the literature on epistemic injustice, although it does not fit squarely. I show this by arguing for what can be understood as a colonial state’s specific manifestation of epistemic injustice. This manifestation takes into account the historical context of colonisation and the continuing (...) coloniality of sub-Saharan African countries. From this, I argue for an approach to remediating this epistemic injustice that relies on the fair-minded pursuit of knowledge. This approach, I briefly argue, gains valuable insights from African epistemological traditions and can be beneficial to other epistemic injustice instances that result specifically from historical cases of oppression.

This article concerns Quentin Meillassoux’s claim that Kant’s revolution is responsible for philosophy’s catastrophic loss of the ‘great outdoors’, of our knowledge of things as they are in themselves. I argue that Meillassoux’s critique of Kant’s ‘weak’ correlationism and his defence of ‘strong’ correlationism are predicated on a fallacious argument (termed ‘the Gem’ by David Stove) and the traditional, but in my view mistaken, metaphysical interpretation of Kant’s transcendental distinction. I draw on Henry Allison’s interpretation of Kant’s idealism to argue (...) that when Kant’s transcendental distinction is understood epistemologically we can avoid the fallacious reasoning underpinning Meillassoux’s argument, and at the very least attenuate his concerns about the ‘Kantian catastrophe’.

The strongest arguments for the permissibility of geoengineering (also known as climate engineering) rely implicitly on non-ideal theory—roughly, the theory of justice as applied to situations of partial compliance with principles of ideal justice. In an ideally just world, such arguments acknowledge, humanity should not deploy geoengineering; but in our imperfect world, society may need to complement mitigation and adaptation with geoengineering to reduce injustices associated with anthropogenic climate change. We interpret research proponents’ arguments as an application of a particular (...) branch of non-ideal theory known as “clinical theory.” Clinical theory aims to identify politically feasible institutions or policies that would address existing (or impending) injustice without violating certain kinds of moral permissibility constraints. We argue for three implications of clinical theory: First, conditional on falling costs and feasibility, clinical theory provides strong support for some geoengineering techniques that aim to remove carbon dioxide from the atmosphere. Second, if some kinds of carbon dioxide removal technologies are supported by clinical theory, then clinical theory further supports using those technologies to enable “overshoot” scenarios in which developing countries exceed the cumulative emissions caps that would apply in ideal circumstances. Third, because of tensions between political feasibility and moral permissibility, clinical theory provides only weak support for geoengineering techniques that aim to manage incoming solar radiation.

This important edited collection addresses ethical issues associated with solar radiation management (SRM), a category of climate engineering techniques that would increase the planet’s reflectivity in order to offset some of the impacts of anthropogenic climate change. Such techniques include injecting sulfate aerosols into the stratosphere or brightening marine clouds with seawater. Although SRM has the potential to cool the planet by reducing the amount of incoming solar radiation absorbed by the planet, it raises a wide array of difficult and (...) interesting ethical issues. Engineering the Climate makes an important contribution to addressing many of these issues. (shrink)

Given the deep disagreement surrounding population axiology, one should remain uncertain about which theory is best. However, this uncertainty need not leave one neutral about which acts are better or worse. We show that as the number of lives at stake grows, the Expected Moral Value approach to axiological uncertainty systematically pushes one towards choosing the option preferred by the Total and Critical Level views, even if one’s credence in those theories is low.

The environment can elicit biological responses such as oxidative stress (OS) and inflammation as a consequence of chemical, physical, or psychological changes. As population studies are essential for establishing these environment-organism interactions, biomarkers of OS or inflammation are critical in formulating mechanistic hypotheses. By using examples of stress induced by various mechanisms, we focus on the biomarkers that have been used to assess OS and inflammation in these conditions. We discuss the difference between biomarkers that are the result of a (...) chemical reaction (such as lipid peroxides or oxidized proteins that are a result of the reaction of molecules with reactive oxygen species) and those that represent the biological response to stress, such as the transcription factor NRF2 or inflammation and inflammatory cytokines. The high-throughput and holistic approaches to biomarker discovery used extensively in large-scale molecular epidemiological exposome are also discussed in the context of human exposure to environmental stressors. We propose to consider the role of biomarkers as signs and to distinguish between signs that are just indicators of biological processes and proxies that one can interact with and modify the disease process.

Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

In “Regulating social media as a public good: Limiting epistemic segregation” (2022), Toby Handfield tackles a well-known problematic aspect of widespread social media use: the formation of ideologically monotone and insulated social networks. Handfield argues that we can take some cues from economics to reduce the extent to which echo chambers grow up around individual users. Specifically, he argues that tax incentives to encourage network heterophily may be levied at any of three different groups: individual social media (...) users, social media sites/companies, or advertisers who use social media to promote their products and material. In this response, I examine the plausibility of using such incentives on each of the these groups. I argue, first, that using tax incentives on either (1) social media companies or (2) advertisers would be ineffective as these incentives could not feasibly be made strong enough to override the enormous financial gain of the standard social media algorithms. Next, I argue that levying the incentives/penalties on individual users would be a hazard, due to the risk of what is called the epistemic “backfire effect”. Finally, I argue that the problem lies in relying on incentives and disincentives—rather than direct regulation—to increase network heterophily. (shrink)

While geoengineering may counteract negative effects of anthropogenic climate change, it is clear that most geoengineering options could also have some harmful effects. Moreover, it is predicted that the benefits and harms of geoengineering will be distributed unevenly in different parts of the world and to future generations, which raises serious questions of justice. It has been suggested that a compensation scheme to redress geoengineering harms is needed for geoengineering to be ethically and politically acceptable. Discussions of compensation for geoengineering (...) harms, however, sometimes presume geoengineering has presented new and unique challenges to compensation that cannot be readily accommodated by existing compensation practices. The most explicit formulation of this view was recently presented by Toby Svoboda and Peter J. Irvine, who argued that two forms of uncertainty in geoengineering — namely, ethical uncertainty and scientific uncertainty — make it immensely difficult to devise an ethically and politically satisfactory compensation scheme for geoengineering harms. -/- In this paper, we argue against the view that geoengineering presents new and unique challenges relating to compensation. More specifically, we show that placing these challenges within the broader context of anthropogenic climate change reveals them to be less serious and less specific to geoengineering than some appear to believe.

In their ‘Ethical and Technical Challenges in Compensating for Harm Due to Solar Radiation Management Geoengineering’ (2014), Toby Svoboda and Peter Irvine (S&I) argue that there are significant technical and ethical challenges that stand in the way of crafting a just solar radiation management (SRM) compensation system. My aim in this article is to contribute to the project of addressing these problems. I do so by focusing on one of S&I’s important ethical challenges, their claim that the polluter pays (...) principle (PPP) is too problematic to be useful in determining responsibility for SRM compensation. Their argument for the latter claim consists in a series of allegations, mostly in the form of questions, that are thought to indicate serious difficulties standing in the way of using the PPP to craft a just compensation system. I argue that S&I fail to substantiate these allegations: the PPP is not as problematic as S&I suggest, and moreover, is a viable candidate for determining responsibility for SRM compensation. S&I raise five allegations against the PPP. I discuss each in turn. (shrink)

The question of the moral demands that humans, posthumans, and nonhumans in the Anthropocene put up on persons now living generally takes the form of supererogatory demands—that is, moral obligations with a perfectionist structure leading to obligations “above and beyond the call of duty” and extreme individual and collective sacrifice. David Roden construes this by deontology; Toby Ord, following Derek Parfit, by consequentualism. Such obligations are akin to the martyrdom of saints: but must our expectations of the Anthropocene necessarily (...) lead to this kind of moral obligation? Can it be mitigated and how? Meta-ethically, it is a highly externalist form of motivation with no concurrent rewards. In this respect, the inquiry is to be pursued through understanding how to align horizons of experience and of expectation. Normatively, it very much concerns how we define and regard persons—present and future, human and non-human, organic or artificial, conscious or not, intelligent or otherwise—since personhood and moral obligation are deeply connected concepts. In my conference paper I want to open and provoke discussion of the current and possible views of the supererogatory moral obligations in and toward the Anthropocene. (shrink)

Some authors have called for increased research on various forms of geoengineering as a means to address global climate change. This paper focuses on the question of whether a particular form of geoengineering, namely deploying sulfate aerosols in the stratosphere to counteract some of the effects of increased greenhouse gas concentrations, would be a just response to climate change. In particular, we examine problems sulfate aerosol geoengineering (SAG) faces in meeting the requirements of distributive, intergenerational, and procedural justice. We argue (...) that SAG faces obstacles to meeting the requirements of all three considered kinds of justice, because its impacts can harm some persons and communities much more than others; it poses serious risks to future generations; and SAG is especially prone to unilateral implementation. While we do not claim that SAG ought not to be implemented, we argue that it is the responsibility of proponents of SAG to recognize and address these ethical obstacles before advocating its implementation.
