The three main types of policies for addressing climate change are command and control regulation, carbon taxes (or price instruments), and cap and trade (or quantity instruments). The first question in the ethics of carbon pricing is whether the latter two (price and quantity instruments) are preferable to command and control regulation. The second question is, if so, how should we evaluate the relative merits of price and quantity instruments. I canvass relevant arguments to explain different ways of addressing these (...) important policy questions, suggesting that carbon pricing is preferable to command and control regulation, and that price instruments have the theoretical edge over quantity instruments.

The coronavirus disease 2019 (COVID-19) crisis ought to serve as a reminder about the costs of failure to consider another long-term risk, climate change. For this reason, it is imperative to consider the merits of policies that may help to limit climate damages. This essay rebuts three common objections to carbon taxes: (1) that they do not change behaviour, (2) that they generate unfair burdens and increase inequality, and (3) that fundamental, systemic change is needed instead of carbon taxes. The (...) responses are (1) that there is both theoretical and empirical reason to think that carbon taxes do change behaviour, with larger taxes changing it to a greater extent; (2) that undistributed carbon taxes are regressive but distributing the tax receipts can alleviate that regressivity (and, in many cases, make the overall effect progressive); and (3) that while small changes for increasing democratic decision-making may be helpful, (fundamental) change takes time and the climate crisis requires urgent action. [Open access] //// -/- La crise de lamaladie à coronavirus 2019 (COVID-19) devrait servir de rappel sur les coûts de la non-prise en compte d’un autre risque à long terme, les changements climatiques. Pour cette raison, il est impératif de considérer lesmérites des politiques susceptibles de contribuer à limiter les changements climatiques. Cet essai réfute trois objections courantes aux taxes sur le carbone : (1) qu’elles ne changent pas les comportements (2) qu’elles génèrent des charges injustes et augmentent les inégalités, et (3) qu’un changement fondamental et systémique est nécessaire au lieu de taxes sur le carbone. Les réponses sont (1) qu’il existe des raisons à la fois théoriques et empiriques de penser que les taxes sur le carbone modifient effectivement les comportements, et que des taxes plus élevées les modifient dans une plus grande mesure; (2) que les taxes sur le carbone non distribuées sont régressives,mais que la distribution des recettes fiscales peut atténuer cette régressivité (et, dans de nombreux cas, rendre l’effet global progressif); et (3) que, bien que de petits changements pour l’amélioration de la prise de décision démocratique peuvent être utiles, un changement (fondamental) prend du temps et la crise climatique exige une action urgente.

Climate ethics has been concerned with polluter pays, beneficiary pays and ability to pay principles, all of which consider climate change as a single negative externality. This paper considers it as a constellation of externalities, positive and negative, with different associated demands of justice. This is important because explicitly considering positive externalities has not to our knowledge been done in the climate ethics literature. Specifically, it is argued that those who enjoy passive gains from climate change owe gains not to (...) the net losers, but to the emitters, just as the emitters owe compensation to the net losers for the negative externality. This is defended by appeal to theoretical virtues and to the social benefits of generating positive externalities, even when those positive externalities are coupled with far greater negative externalities. We call this the Polluter Pays, Then Receives ('PPTR', or 'Peter') Principle. This principle is then applied at two levels in the context of Canada. [Open access]. (shrink)

This chapter introduces several distinctions relevant to what is called the “discounting problem”, since the issue is how (future) costs and benefits are discounted to make them comparable in present terms. The author defends the claim that there are good reasons to adopt Ramsey-style discounting in the context of climate change: the Ramsey rule is robust, flexible, and well-understood. An important distinction involved in discounting—“descriptivism” and “prescriptivism”—is discussed. It is argued that, even if we adopt prescriptivism, and accept that this (...) means there is need for moral experts in parameter assignments, there is a significant issue. The type of moral expertise required for the discounting problem will not involve knowledge of moral theory—thus making moral philosophy unhelpful in terms of making particular parameter assignments, despite these being substantive moral judgments.

Parfit denies that the introduction of reasons into our ontology is costly for his theory. He puts forth two positions to help establish the claim: the Plural Senses View and the Argument from Empty Ontology. I argue that, first, the Plural Senses View for ‘exists’ can be expanded to allow for senses which undermine his ontological claims; second, the Argument from Empty Ontology can be debunked by Platonists. Furthermore, it is difficult to make statements about reasons true unless these statements (...) include reference to objects in reality. These arguments show the instability of Parfit’s claimed metaethical advantages over naturalism. [Open access]. (shrink)

Utility discounting in intertemporal economic modelling has been viewed as problematic, both for descriptive and normative reasons. However, positive utility discount rates can be defended normatively; in particular, it is rational for future utility to be discounted to take into account model-independent outcomes when decision-making under risk. The resultant values will tend to be smaller than descriptive rates under most probability assignments. This also allows us to address some objections that intertemporal considerations will be overdemanding. A principle for utility discount (...) rates is suggested which is rooted in probability discounting. Utility discounting is defended against objections from Parfit (1984) and Broome (2005); Broome (2012). A sample utility discount rate is estimated. [Open access]. (shrink)

When probability discounting (or probability weighting), one multiplies the value of an outcome by one's subjective probability that the outcome will obtain in decision-making. The broader import of defending probability discounting is to help justify cost-benefit analyses in contexts such as climate change. This chapter defends probability discounting under risk both negatively, from arguments by Simon Caney (2008, 2009), and with a new positive argument. First, in responding to Caney, I argue that small costs and benefits need to be evaluated, (...) and that viewing practices at the social level is too coarse-grained. Second, I argue for probability discounting using a distinction between causal responsibility and moral responsibility. Moral responsibility can be cashed out in terms of blameworthiness and praiseworthiness, while causal responsibility obtains in full for any effect which is part of a causal chain linked to one's act. With this distinction in hand, unlike causal responsibility, moral responsibility can be seen as coming in degrees. My argument is, given that we can limit our deliberation and consideration to that which we are morally responsible for and that our moral responsibility for outcomes is limited by our subjective probabilities, our subjective probabilities can ground probability discounting.

This paper puts forward two claims about funding carbon capture and storage. The first claim is that there are moral justifications supporting strategic investment into CO2 storage from global and regional perspectives. One argument draws on the empirical evidence which suggests carbon capture and storage would play a significant role in a portfolio of global solutions to climate change; the other draws on Rawls' notion of legitimate expectations and Moellendorf's Anti-Poverty principle. The second claim is that where to pursue this (...) strategic investment poses a morally non-trivial problem, with considerations like near-term global distributive justice and undermining legitimate expectations favouring investing in developing regions, especially in Asia, and considerations like long-term climate impacts and best uses of resources favouring investing in the relatively wealthy regions that have the best prospects for successful storage development.

A question arising from the COVID-19 crisis is whether the merits of cases for climate policies have been affected. This article focuses on carbon pricing, in the form of either carbon taxes or emissions trading. It discusses the extent to which relative costs and benefits of introducing carbon pricing may have changed in the context of COVID-19, during both the crisis and the recovery period to follow. In several ways, the case for introducing a carbon price is stronger during the (...) COVID-19 crisis than under normal conditions. Oil costs are lower than normal, so we would expect less harm to consumers compared to normal conditions. Governments have immediate need for diversified new revenue streams in light of both decreased tax receipts and greater use of social safety nets. Finally, supply and demand shocks have led to already destabilized supply-side activities, and carbon pricing would allow this destabilization to equilibrate around greener production for the long-term. The strengthening of the case for introducing carbon pricing now is highly relevant to discussions about recovery measures, especially in the context of policy announcements from the European Union and United States House of Representatives. Key Policy Insights: • Persistently low oil prices mean that consumers will face lower pain from carbon pricing than under normal conditions. • Many consumers are more price-sensitive during the COVID-19 context, which suggests that a greater relative burden from carbon prices would fall upon producers as opposed to consumers than under normal conditions. • Carbon prices in the COVID-19 context can introduce new revenue streams, assisting with fiscal holes or with other green priorities. • Carbon pricing would contribute to a more sustainable COVID-19 recovery period, since many of the costs of revamping supply chains are already being felt while idled labor capacity can be incorporated into firms with lower carbon-intensity.

Ideal carbon tax policy is internationally coordinated, fully internalizes externalities, redistributes revenues to those harmed, and is politically acceptable, generating predictable market signals. Since nonideal circumstances rarely allow all these conditions to be met, moral issues arise. This paper surveys some of the work in moral philosophy responding to several of these issues. First, it discusses the moral drivers for estimates of the social cost of carbon. Second, it explains how national self-interest can block climate action and suggests international policies—carbon (...) border tax adjustments and carbon clubs—that can help address these concerns. Third, it introduces some of the social science literature about the political acceptability of carbon taxes before addressing a couple common public concerns about carbon taxes. Finally, it introduces four carbon revenue usage options, arguing that redistributive and climate compensation measures are most morally justified. [Open access]. (shrink)

While mitigation and adaptation will help to protect us from climate change, there are harms that are beyond our ability to adapt. Some of these harms, which may have been instigated from historical emissions, plausibly give rise to duties of compensation. This chapter discusses several principles that have been discussed about how to divide climate duties—the polluter pays principle, the beneficiary pays principle, the ability to pay principle, and a new one, the polluter pays, then receives principle. The chapter introduces (...) several challenges to these principles from the literature, before discussing which policies and institutions might be relevant to compensation, whether internationally (e.g. the Green Climate Fund) or intergenerationally (e.g. Broome and Foley’s World Climate Bank). It also describes some recent successful climate cases which require both the Dutch government and a private firm to act in accordance with climate targets to avoid potential rights-violations. Finally, it discusses one of the most important international concepts with respect to compensation: the Loss & Damage pillar of climate policy. (shrink)

Luke Elson defends carbon offsetting on the basis that it is not morally objectionable to shift harms or risks around. As long as emitting and offsetting does not increase the overall harms or risks—and merely shifts them—compared to refraining from emitting, he suggests there is no injustice involved. I respond in several ways, suggesting that the time delay involved in offsetting can increase these risks but, regardless, there is a defensible default which could justify refraining from emitting, even when planning (...) to offset.

Throughout the COVID-19 pandemic, shortages of scarce healthcare resources consistently presented significant moral and practical challenges. While the importance of vaccines as a key pharmaceutical intervention to stem pandemic scarcity was widely publicized, a sizable proportion of the population chose not to vaccinate. In response, some have defended the use of vaccination status as a criterion for the allocation of scarce medical resources. In this paper, we critically interpret this burgeoning literature, and describe a framework for thinking about vaccine-sensitive resource (...) allocation using the values of responsibility, reciprocity, and justice. Although our aim here is not to defend a single view of vaccine-sensitive resource allocation, we believe that attending critically with the diversity of arguments in favor (and against) vaccine-sensitivity reveals a number of questions that a vaccine-sensitive approach to allocation should answer in future pandemics.

First, with respect to our personal relationship to fossil fuels, this chapter introduces arguments about whether we should or even can address our own usage of fossil fuels. This involves determining whether offsetting emissions is morally required and practically possible. Second, with respect to our relationship with fossil fuels at the national level, it discusses forms of local resistance, especially divestment and pipeline protesting. Finally, with respect to our relationship with fossil fuels at the international level, it considers two types (...) of policy. On the one hand, some have argued that we should stop most trade in oil, on the basis that most oil that is traded is not subject to the control of citizens. On the other hand, some have argued that we should price the costs of fossil fuels so that there are market incentives to avoid digging them out of the ground. (shrink)

This chapter qualitatively lays out some of the ways that climate change impacts are evaluated in integrated assessment models (IAMs). Putting aside the physical representations of these models, it first discusses some key social or structural assumptions, such as the damage functions and the way growth is modeled. Second, it turns to the moral assumptions, including parameters associated with intertemporal evaluation and interpersonal inequality aversion, but also assumptions in population ethics about how different-sized populations are compared and how we think (...) about distributing goods across or within times. The intention is to survey the morally important assumptions that go into estimates of the social cost of carbon, the marginal cost of an additional tonne of carbon dioxide to society. (shrink)

[Opinion] This aims to begin deliberation about investing in negative emissions technologies (NETs) by suggesting that the investment could be responsive to two particular values: need and efficiency—and that these values point us towards taking different actions. For negative emissions technologies, I suggest, we face a Need-Efficiency Tradeoff, i.e. a “NET effect”. This tradeoff also highlights several contrasts: responding to need focuses on regional and short-term moral considerations; responding to efficiency focuses on global and long-term moral considerations.

This Correspondence argues in response to Coolsaet et al. (2024) that there is an important role to play for stance-independent justice discussions that are not tied to specific social, political or critical perspectives. These can be valuable for climate research audiences, but also as a basis upon which to critically debate and research injustices.

Neil Tennant was the first to propose a proof-theoretic criterion for paradoxicality, a framework in which a paradox, formalized through natural deduction, is derived from an unacceptable conclusion that employs a certain form of id est inferences and generates an infinite reduction sequence. Tennant hypothesized that any derivation in natural deduction that formalizes a genuine paradox would meet this criterion, and he argued that while the liar paradox is genuine, Russell's paradox is not. -/- The present paper delves into Tennant's (...) conjecture for genuine paradoxes and suggests that to validate the conjecture, one of two issues must be addressed. The first issue is the need for a philosophical consensus on the identification of a genuine paradox in an informal sense. The second issue is the requirement for a uniform approach to formalize paradoxes in natural deduction. If either of these issues is addressed, the conjecture could be validated, or at the very least, it could hold philosophical importance in delineating the proof-theoretic features of paradoxicality.

One branch of the responsible innovation literature involves the direction of innovation: if the public or decision-makers can or should direct innovation, how should innovation be directed? This paper explicates a case study where directionality – the plurality of plausible values for innovation – is directly implicated. In this case, a key technology may require a strategy for innovation, but there are contrasting normative reasons to drive that innovation in different ways, reflecting two distinct moral values, ‘effectiveness’ and responsiveness to (...) ‘need’. In this case, carbon dioxide removal, these values may well conflict. Strategically deploying carbon dioxide removal in a cost-effective manner would tend to support siting it in regions where there are significant oil and gas operations. In contrast, strategically deploying carbon dioxide removal in response to need would tend to support siting it in regions where expected demand for the technology is required for development.

[Comment] I am sympathetic to Avner de Shalit’s position that a political philosophy should incorporate public values, but I see their role differently. Philosophers of science standardly distinguish between values being introduced in the context of discovery (inputs into the investigation or arguments) and in the context of justification (acceptance or rejection of substantive claims in light of the arguments or investigation). I argue that de Shalit is wrong to put the public values in the context of discovery; with respect (...) to normative theories (such as political theories), the values should be introduced in the context of justification.

In this article, we claim that recent developments in climate science and renewable energy should prompt a reframing of debates surrounding climate change mitigation. Taken together, we argue that these developments suggest (1) global climate collapse in this century is a non-negligible risk, (2) mitigation offers substantial benefits to current generations, and (3) mitigation by some can generate social tipping dynamics that could ultimately make renewables cheaper than fossil fuels. We explain how these claims undermine familiar framings of climate change, (...) wherein mitigation is understood as self-sacrifice that individuals and governments must be morally persuaded or incentivized to undertake.

While there are a variety of moral issues that relate to carbon pricing policies, I will focus on one that has received a large amount of attention: is carbon pricing unjust? Campaigners and civil society groups, especially those involved in environmental and climate justice spaces, have rejected carbon pricing as unjust. This claim deserves some discussion and, in this perspective, I discuss a few potential dimensions of justice that could be relevant to this claim. My goal is to show that, (...) for the most important dimensions of justice, distributive and procedural, carbon pricing is not unjust as a policy instrument for addressing climate change.

In the first half, I suggest that Kant’s conception of our moral life goes through a significant shift after 1793, with reverberations in his eschatology. The earlier account, based on the postulate of immortality, describes our moral life as an endless pursuit of the highest good, but all this changes in the later account, and I point out three possible reasons for this change of heart. In the second half, I explore how the considerations Kant brings up to argue for (...) his accounts can inform our process of formulating positions with respect to the afterlife. I argue that, in the absence of a convincing theoretical proof for or against the afterlife as well as apodictically certain knowledge of how demanding the moral law is, the Kantian strategy would be to ask which account of our moral life delivers the kind of contentment that can sustain our moral resolve. I also point out a way theists might be able to find contentment despite their moral failures by imagining God’s moral kenosis. (shrink)

Introduction The Defining Issues Test (DIT) aimed to measure one’s moral judgment development in terms of moral reasoning. The Neo-Kohlbergian approach, which is an elaboration of Kohlbergian theory, focuses on the continuous development of postconventional moral reasoning, which constitutes the theoretical basis of the DIT. However, very few studies have directly tested the internal structure of the DIT, which would indicate its construct validity. Objectives Using the DIT-2, a later revision of the DIT, we examined whether a bi-factor model or (...) 3-factor CFA model showed a better model fit. The Neo-Kohlbergian theory of moral judgment development, which constitutes the theoretical basis for the DIT-2, proposes that moral judgment development occurs continuously and that it can be better explained with a soft-stage model. Given these assertions, we assumed that the bi-factor model, which considers the Schema-General Moral Judgment (SGMJ), might be more consistent with Neo-Kohlbergian theory. Methods We analyzed a large dataset collected from undergraduate students. We performed confirmatory factor analysis (CFA) via weighted least squares. A 3-factor CFA based on the DIT-2 manual and a bi-factor model were compared for model fit. The three factors in the 3-factor CFA were labeled as moral development schemas in Neo-Kohlbergian theory (i.e., personal interests, maintaining norms, and postconventional schemas). The bi-factor model included the SGMJ in addition to the three factors. Results In general, the bi-factor model showed a better model fit compared with the 3-factor CFA model although both models reported acceptable model fit indices. Conclusion We found that the DIT-2 scale is a valid measure of the internal structure of moral reasoning development using both CFA and bi-factor models. In addition, we conclude that the soft-stage model, posited by the Neo-Kohlbergian approach to moral judgment development, can be better supported with the bi-factor model that was tested in the present study.

We evaluated the reliability, validity, and differential item functioning (DIF) of a shorter version of the Defining Issues Test-1 (DIT-1), the behavioral DIT (bDIT), measuring the development of moral reasoning. 353 college students (81 males, 271 females, 1 not reported; age M = 18.64 years, SD = 1.20 years) who were taking introductory psychology classes at a public University in a suburb area in the Southern United States participated in the present study. First, we examined the reliability of the bDIT (...) using Cronbach’s α and its concurrent validity with the original DIT-1 using disattenuated correlation. Second, we compared the test duration between the two measures. Third, we tested the DIF of each question between males and females. Findings reported that first, the bDIT showed acceptable reliability and good concurrent validity. Second, the test duration could be significantly shortened by employing the bDIT. Third, DIF results indicated that the bDIT items did not favour any gender. Practical implications of the present study based on the reported findings are discussed. (shrink)

[Newspaper opinion] strengthening carbon pricing during COVID-19 is the best time to do so for both consumers and for governments.

[Newspaper opinion] To give carbon storage sites the greatest chance of success, it makes sense to develop them in places where the geology has been thoroughly explored and where there is lots of relevant expertise. This would imply pumping carbon into underground storage sites in northern Europe, the Middle East and the US, where companies have spent centuries looking for and extracting fossil fuels. On the other hand, it might be important to develop storage sites in economies where the current (...) and future demand for carbon capture and storage is greatest.

Non-technical summary: -/- When developing and deploying negative emissions technologies (NETs), little attention has been paid to where. On the one hand, one might develop NETs where they are likely to contribute most to global mitigation targets, contributing to a global climate solution. On the other hand, one might develop NETs where they can help support development on a regional basis, justified by regional demands. I defend these arguments and suggest that they reflect the values of efficiency and responding to (...) need, respectively. To the extent that these values conflict, they introduce what I call the Need-Efficiency Trade-off Effect (‘NET Effect’). -/- Technical summary: -/- Unlike other geoengineering methods, the effectiveness of negative emissions technologies (NETs) tends to be sensitive to regional siting. This paper argues that this point raises morally and legally important implications by identifying a trade-off between ‘efficiency’ and ‘need’. First, it introduces two arguments justifying NETs: one focused on contributions to global mitigation and the other focused on contributions to regional development. Second, reflecting the two arguments, the paper discusses the moral values of efficiency and need, respectively. For instance, if the strategy is to try to use NETs to maximize expected mitigation contributions to reflect efficiency, then deployment should occur in regions with the best prospects for success (e.g. Western countries). However, if the strategy is to try to use NETs to improve the chances of simultaneous development and mitigation to respond to need, then deployment should occur in regions with limited development and expected growth of demand for NETs (e.g. Asian countries). When these values conflict, I call that a Need-Efficiency Trade-off Effect (‘NET Effect’). The paper concludes by considering the NET Effect in the context of bioenergy with carbon capture and storage as well as direct air carbon capture and storage. [Open access]. (shrink)

Worldwide populations are aging with economic development as a result of public health initiatives and advances in therapeutic discoveries. Since 1850, life expectancy has advanced by 1 year for every four. Accompanying this change is the rapid development of anti‐aging science. There are three schools of thought in the field of aging science. One perspective is the life course approach, which considers that aging is a good and natural process to be embraced as a necessary and positive aspect of life, (...) where the aim is to improve the quality of existing lifespan and “compress” morbidity. Another view is that aging is undesirable, and that rejuvenation and indeed immortality are possible since the biological basis of aging is understood, and therefore, strategies are possible for engineering negligible senescence. Finally, a hybrid approach is that life span can be extended by anti‐aging medicines but with uncertain effects on health. While these advances offer much promise, the ethical perspectives are seldom discussed in cross‐disciplinary settings. This article discusses some of the key ethical issues arising from recent advances in biogerontology. (shrink)

Food prices are a daily concern in many households’ decision-making, especially when people want to have healthier diets. Employing Bayesian Mindsponge Framework (BMF) analytics on a dataset of 710 Indonesian citizens, we found that people from wealthier households are less likely to have concerns about food prices. However, the degree of health considerations in food consumption was found to moderate against the above association. In other words, people of higher income-based social classes may worry more about food prices if they (...) care more about the health impacts of their food choices. These findings provide more insights for policymakers on the psychological aspects of promoting the balance between finance and health in food consumption. (shrink)

The present paper investigates whether strictly classical inferences contribute to the formalization of (genuine) paradoxes within natural deduction. Tennant's criterion for paradoxicality relies on the generation of an infinite reduction sequence, which distinguishes genuine paradoxes from mere inconsistencies. His methodological conjecture posits that genuine paradoxes are never strictly classical and can be derived without classical inferences such as the Law of Excluded Middle, Dilemma, Classical Reductio, and Double Negation Elimination. -/- It appears that there were two reasons for Tennant's proposal (...) of the methodological conjecture. The one is that strictly classical inferences hinder the generation of an infinite reduction sequence and the other is that strictly classical inferences have no role in the formalization of genuine paradoxes. -/- This paper raises questions about these two reasons. Focusing on the liar paradox, it will be argued that strictly classical inferences do not interfere with the generation of an infinite reduction sequence and that the liar sentence may implicitly entail strictly classical inferences. Should this analysis hold, it would call into question not only Tennant’s motivation for advancing the methodological conjecture, but also challenge his contention that genuine paradoxes—exemplified by the liar paradox—are never constructed with reliance on strictly classical inferences.

In this dissertation, we shall investigate whether Tennant's criterion for paradoxicality(TCP) can be a correct criterion for genuine paradoxes and whether the requirement of a normal derivation(RND) can be a proof-theoretic solution to the paradoxes. Tennant’s criterion has two types of counterexamples. The one is a case which raises the problem of overgeneration that TCP makes a paradoxical derivation non-paradoxical. The other is one which generates the problem of undergeneration that TCP renders a non-paradoxical derivation paradoxical. Chapter 2 deals with (...) the problem of undergeneration and Chapter 3 concerns the problem of overgeneration. Chapter 2 discusses that Tenant’s diagnosis of the counterexample which applies CR−rule and causes the undergeneration problem is not correct and presents a solution to the problem of undergeneration. Chapter 3 argues that Tennant’s diagnosis of the counterexample raising the overgeneration problem is wrong and provides a solution to the problem. Finally, Chapter 4 addresses what should be explicated in order for RND to be a proof-theoretic solution to the paradoxes. (shrink)

Simion and Kelp explain the trustworthiness of an AI based on that AI’s disposition to meet its obligations. Roughly speaking, according to Simion and Kelp, an AI is trustworthy regarding its task if and only if that AI is obliged to complete the task and its disposition to complete the task is strong enough. Furthermore, an AI is obliged to complete a task in the case where the task is the AI’s etiological function or design function. This account has a (...) strength in that it can provide a unificatory rationale for the trustworthy-making properties of AIs. According to this account, being explainable, being safe, and being transparent are the trustworthy-making properties of an AI because an AI can fulfill its etiological or design functions in the case where it is explainable, safe, and transparent. This paper shows that though Simion and Kelp’s account has a strength, this account is not satisfactory for two reasons. The first reason is that an AI’s trustworthiness is not determined just by the AI’s disposition to meet obligations, and the second reason is that it is difficult to explain how an AI’s etiological function and design function have to do with that AI’s obligations. To provide a full-fledged account, Simion and Kelp should dismiss these concerns. (shrink)

Climate change prevention necessitates the communication of transparent and reliable scientific evidence to improve public awareness and support. Felt responsibility is an essential factor influencing human environment-related psychology and behavior. However, the knowledge about the relationship between the felt responsibility and perceived uncertainty of scientific evidence regarding climate change has remained limited. The current study examines factors associated with the perceived uncertainty of scientific evidence (including felt responsibility to act on climate change) among stakeholders of marine and coastal ecosystems in (...) 42 countries. Employing the Bayesian Mindsponge Framework (BMF) analytics on a dataset of 709 stakeholders generated by MaCoBioS—a research project funded by the European Commission Horizon 2020, we reveal several main insights. Stakeholders with lower educational levels, being males and not from high-income countries, are more likely to think scientific evidence regarding how to act on climate change is uncertain. Moreover, people with a higher felt responsibility to act on climate change are also more likely to perceive higher uncertainty of scientific evidence. Based on these findings, we discuss how scientific evidence should be communicated to build the eco-surplus culture and, subsequently, the felt responsibility of stakeholders while inoculating them from climate change misinformation and disinformation.

In the beginning of his critical period, Kant treated the perfect attainment of the highest good—the unconditioned totality of ends which would uphold the perfect proportionality between moral virtue and happiness—as both the ground of hope for deserved happiness and the final end of our moral life. But I argue that Kant moved in the direction of de-emphasizing the latter aspect of the highest good, not because it is inappropriate or impossible for us to promote this ideal, but because the (...) endless pursuit of it offers no prospect of moral satisfaction. I take this change as one possible reason for him to shift his focus more toward social and political progress in history, which has as its main subject the human species which is in some sense immortal.

I show how those with Kantian habits of mind—those committed to maintaining certain kinds of universality in ethics—can still get involved in the project of securing the distinctiveness of Christian ethics by highlighting parts of his moral philosophy that are amenable to this project. I first describe the interaction among James Gustafson, Stanley Hauerwas, and Samuel Wells surrounding the issue of the distinctiveness of Christian ethics, to explain why Kant is generally understood as the opponent of this project in this (...) discourse. Then I lay out his discussions of how his moral argument for postulating divine existence can have beneficial moral-psychological results, and of how we can find moral satisfaction, the sense of pleasure in our moral strivings, as two elements in his moral philosophy that can be turned into a distinctively Christian ethics with revisions that should be allowed within the broad confines of Kantian moral philosophy. I also point out that his own answer to the question of moral satisfaction is already distinctively Christian, in that it is inspired by the Christian tenets of the imputation of righteousness and the assurance of salvation.

Chapter 1 What Do Zen Masters Teach Us Today? The Case of Sŏn Master Hyeam Sŏnggwan Jin Y. Park Introduction Korean Sŏn Master Hyeam Sŏnggwan (慧菴性觀, 1920–2001) is a relatively unknown figure within English-language scholarship.1 However, among Korean Buddhists, his rigorous Zen practice has been well recognized. One-meal-per-day (K. ilchongsik 一種食), no-meal-in-the-afternoon (K. ohu pulsik 午後不食), and staying-sitting-in-meditation-without-lying-down (K. changjwa purwa 長坐不臥) are all well-known practices that frequently appear when describing Hyeam as a Zen master. What is less frequently asked (...) is what these rigorous Zen practices might mean to us commoners who live in a secular world or to monastics whose practice might not be as rigorous as Hyeam’s. Should Zen masters such as Hyeam who appear to exhibit superhuman capacity for religious practice be only an object of awe and admiration in our secular modern times? Even if so, what do the awe and admiration indicate? In this chapter, I try to bridge the gap between the rigorous practice typically seen in Korean Zen masters’ lives and its meaning for people living in modern times. What questions does a Zen master like Hyeam raise for us, and how should scholars address these issues? These are the inquiries with which I hope to engage. (shrink)

This chapter lays out what we take to be the main types of justice and ethical challenges concerning those adverse effects of climate change leading to climate-related Loss and Damage (L&D). We argue that it is essential to clearly differentiate between the challenges concerning mitigation and adaptation and those ethical issues exclusively relevant for L&D in order to address the ethical aspects pertaining to L&D in international climate policy. First, we show that depending on how mitigation and adaptation are distinguished (...) from L&D, the primary focus of policy measures and their ethical implications will vary. Second, we distinguish between a distributive justice framework and a compensatory justice scheme for delivering L&D measures. Third, in order to understand the differentiated remedial responsibilities concerning L&D, we categorise the measures and policy approaches available. Fourth, depending on the kind of L&D and which remedies are possible, we explain the difference between remedial and outcome responsibilities of different actors. [Open access]. (shrink)

该研究简要介绍了儒家、佛教和道教在越南的起源和发展，以及它们如何通过 "文化叠加性 "来共存、互动、影响越南社会。基于文化叠加性的成本效益分析，本文进一步说明了儒家思想如何在越南社会中占主导地位，道教思想如何与儒家思想共存，以及为什么佛教影响力逐渐在越南民间消失。.

Climate change and decarbonization raise complex justice questions that researchers and policymakers must address. The distributions of greenhouse gas emissions rights and mitigation efforts have dominated justice discourses within scenario research, an integrative element of the IPCC. However, the space of justice considerations is much larger. At present, there is no consistent approach to comprehensively incorporate and examine justice considerations. Here we propose a conceptual framework grounded in philosophical theory for this purpose. We apply this framework to climate mitigation scenarios (...) literature as proof of concept, enabling a more holistic and multidimensional investigation of justice. We identify areas of future research, including new metrics of service provisioning essential for human well-being. [Can be freely read by clicking the ReadCube link below.]. (shrink)

[Newspaper Opinion] Before the COVID-19 pandemic and the accompanying fall in oil prices, a carbon price would have been immediately painful for the countries that imposed it, but far better for everyone over the longer term. In this unprecedented moment, introducing a carbon price would be beneficial both now and for the future.

While investigating the value of achievements, Dunkle claims that lucky achievements are possible. For instance, if a person does great works, then it is possible that the works have the status of achievements, even if luck plays a crucial role in doing the great works. Rather than examining Dunkle’s claim, this paper proceeds discussion under the assumption that lucky achievements are possible. In particular, based on this assumption, this paper suggests a new approach to the nature of achievement named the (...) Comparative Value Approach. According to the comparative value approach, a product can have the status of an achievement if the product is valuable in an achievement-relevant domain, and in that domain the product is valuable more than most other items which either have been achieved or can be achieved by others. This paper shows that the comparative value approach successfully explains the cases of achievements, including the cases of lucky achievements. Besides this reason, this paper provides three more reasons to show that the comparative value approach is a feasible view of achievements. The comparative value approach can accommodate the fact that there are various kinds of achievements; the approach can explain the relation between the nature of achievement and the achievement-value of a product; and the approach can show why in determining the status of a product it matters that for average people achieving a similar kind of product is sufficiently difficult. Based on these four reasons, this paper concludes that the comparative value approach is a plausible understanding of achievements. (shrink)

In the present paper, we prove the normalization theorem and the consistency of the first-order classical logic with disjunctive syllogism. First, we propose the natural deduction system SCD for classical propositional logic having rules for conjunction, implication, negation, and disjunction. The rules for disjunctive syllogism are regarded as the rules for disjunction. After we prove the normalization theorem and the consistency of SCD, we extend SCD to the system SPCD for the first-order classical logic with disjunctive syllogism. It can be (...) shown that SPCD is conservative extension to SCD. Then, the normalization theorem and the consistency of SPCD are given. (shrink)

The redemption thesis assumes that how events in a person’s life are related to one another is important in evaluating the person’s welfare throughout life. In particular, according to this thesis of welfare, the fact that a person’s previous hardships contribute to bringing out the same person’s later successes, and the person would regard the hardships as having been worthwhile in light of the successes makes the person’s life better for the person herself. Recently, Ian D. Dunkle provided four objections (...) to the redemption thesis: the intuition concern, the different redemptions argument, the downplaying hardships argument, and the reconciled irreconcilables argument. This paper examines these four objections. In particular, this paper dismisses all the objections showing that the redemption thesis bases on an appealing idea, does not consider the degree of hardship significant in itself, has plausible reasons to evaluate hardships not as serious as people think, and can successfully reconcile its synchronic and diachronic evaluations.

Some goals have special significance to agents. For instance, an agent could find her life worth living because she is pursuing her current goal, and the agent could also think that her previous life has no value because she did not pursue the current goal. If an agent’s current goal has special importance to the agent, then in terms of prudence the agent’s decision to obtain her current goal could be permissible even in the case where achieving her previous goal (...) brings out larger advantages. A widely endorsed thesis of prudence (i.e. the temporal neutrality thesis) does not successfully explain this phenomenon of goal achievement. Furthermore, the present-aim thesis and the harmony thesis also fail in explaining why an agent has prudential reason to prioritize her current goal. This paper introduces a new thesis of prudence, according to which an agent’s caring is significant in deciding whether the agent’s actions are prudentially permissible. In particular, after introducing this thesis named the care thesis, I argue that the care thesis can explain why an agent has reason to prioritize her current goal if the agent finds her life worth living due to her current goal. It is permissible that an agent obtains her current goal rather than previous goal because achieving her current goal benefits the agent’s cared one (i.e. the self who pursues her current goal).

"If a tree falls in a forest and no one is around to hear it, does it make a sound?" In this article I examine the framework of George Berkeley's global metaphysical theory, 'Esse est Percipi'. Then I highlight two competing potential interpretations of the theory.
