Epistemic logics based on the possible worlds semantics suffer from the problem of logical omniscience, whereby agents are described as knowing all logical consequences of what they know, including all tautologies. This problem is doubly challenging: on the one hand, agents should be treated as logically non-omniscient, and on the other hand, as moderately logically competent. Many responses to logical omniscience fail to meet this double challenge because the concepts of knowledge and reasoning are not properly separated. In this paper, (...) I present a dynamic logic of knowledge that models an agent’s epistemic state as it evolves over the course of reasoning. I show that the logic does not sacrifice logical competence on the altar of logical non- omniscience. (shrink)

A theory of learning for the future advocates the teaching of a preparedness to respond in a creative way to difference and otherness. This includes an ability to act imaginatively in situations of uncertainties. John Dewey’s pragmatism holds the key to such a learning theory his view of the continuous meetings of individuals and environments as experimental and playful. That pragmatism has not yet been acknowledged as a relevant learning theory for the future may be due to the immediate connotation (...) and the many interpretations associated with the term ‘experience’, which is at the heart of Dewey’s educational thinking. Dewey defi ned experience in a way that is not well understood within educational research, and in a way that is easily confused with the term ‘experiential learning’. The latter refers to the importance of participants’ ‘experiences’ derived from bodily actions and stored in memory as more or less tacit knowledge. (shrink)

This article argues that, as commonly understood, indirect discrimination is not necessarily unjust: 1) indirect discrimination involves the disadvantaging in relation to a particular benefit and such disadvantages are not unjust if the overall distribution of benefits and burdens is just; 2) indirect discrimination focuses on groups and group averages and ignores the distribution of harms and benefits within groups subjected to discrimination, but distributive justice is concerned with individuals; and 3) if indirect discrimination as such is unjust, strict egalitarianism (...) has to be the correct account of distributive justice, but such egalitarianism appears vulnerable to the leveling down objection (whether decisively or not), and many theorists explicitly reject strict egalitarianism anyway. The last point threatens the position of liberals who oppose indirect discrimination but think significant inequalities can be just. (shrink)

In this study I analyse the performance of a democratic decision-making rule: the weighted majority rule. It assigns to each voter a number of votes that is proportional to her stakes in the decision. It has been shown that, for collective decisions with two options, the weighted majority rule in combination with self-interested voters maximises the common good when the latter is understood in terms of either the sum-total or prioritarian sum of the voters’ well-being. The main result of my (...) study is that this argument for the weighted majority rule — that it maximises the common good — can be improved along the following three main lines. (1) The argument can be adapted to other criteria of the common good, such as sufficientarian, maximin, leximin or non-welfarist criteria. I propose a generic argument for the collective optimality of the weighted majority rule that works for all of these criteria. (2) The assumption of self-interested voters can be relaxed. First, common-interest voters can be accommodated. Second, even if voters are less than fully competent in judging their self-interest or the common interest, the weighted majority rule is weakly collectively optimal, that is, it almost certainly maximises the common good given large numbers of voters. Third, even for smaller groups of voters, the weighted majority rule still has some attractive features. (3) The scope of the argument can be extended to decisions with more than two options. I state the conditions under which the weighted majority rule maximises the common good even in multi-option contexts. I also analyse the possibility and the detrimental effects of strategic voting. Furthermore, I argue that self-interested voters have reason to accept the weighted majority rule. (shrink)

Construed as a theory of justice, relational egalitarianism says that justice requires that people relate as equals. Construed as a theory of what makes democracy valuable, it says that democracy is a necessary, or constituent, part of the value of relating as equals. Typically, relational egalitarians want their theory to provide both an account of what justice requires and an account of what makes democracy valuable. We argue that relational egalitarians with this dual ambition face the justice-democracy dilemma: Understanding social (...) relations in such a way that renders relational egalitarianism plausible as an answer to what makes democracy valuable comes at the price of understanding social relations in a way that makes it less plausible as a theory of justice, and vice versa. We also argue that there is no easy way out of the dilemma and that relational egalitarians, who want relational equality to provide both accounts mentioned, may simply have to set their ambitions lower on behalf of relational equality.

In recent years, there have been many attempts at defining learning as a social phenomenon as opposed to an individual and primarily psychological matter. The move towards understanding learning as social processes has also altered the concept of knowledge as a well-defined element stored in books, brains, CD-Roms, disks, videos or on the Internet. Instead, knowledge has been perceived as a social and context related construction. The roots of the social angle within theories on learning and knowledge are much older (...) than the current literature suggests. This paper illustrates how these theories can be traced back to pragmatism as a philosophy and foundation for an educational approach introduced by the American, John Dewey, more than one hundred years ago. The paper also suggests that Dewey avoids some pitfalls that have come with the new theories, particularly the strong division between individual vs. social and school vs. everyday life learning.

One well-known objection to the traditional Lewis-Stalnaker semantics of counterfactuals is that it delivers counterintuitive semantic verdicts for many counterpossibles (counterfactuals with necessarily false antecedents). To remedy this problem, several authors have proposed extending the set of possible worlds by impossible worlds at which necessary falsehoods may be true. Linguistic ersatz theorists often construe impossible worlds as maximal, inconsistent sets of sentences in some sufficiently expressive language. However, in a recent paper, Bjerring (2014) argues that the “extended” Lewis-Stalnaker semantics delivers (...) the wrong truth-values for many counterpossibles if impossible worlds are required to be maximal. To make room for non-maximal or partial impossible worlds, Bjerring considers two alternative world-ontologies: either (i) we construe impossible worlds as arbitrary (maximal or partial) inconsistent sets of sentences, or (ii) we construe them as (maximal or partial) inconsistent sets of sentences that are closed and consistent with respect to some non-classical logic. Bjerring raises an objection against (i), and suggests that we opt for (ii). In this paper, I argue, first, that Bjerring’s objection against (i) conflates two different conceptions of what it means for a logic to be true at a world. Second, I argue that (ii) imposes too strong constraints on what counts as an impossible world. I conclude that linguistic ersatzists should construe impossible worlds as arbitrary (maximal or partial) inconsistent sets of sentences. (shrink)

Kymlicka has offered an influential luck egalitarian justification for a catalogue of polyethnic rights addressing cultural disadvantages of immigrant minorities. In response, Quong argues that while the items on the list are justified, in the light of the fact that the relevant disadvantages of immigrants result from their choice to immigrate, (i) these rights cannot be derived from luck egalitarianism and (ii) that this casts doubt on luck egalitarianism as a theory of cultural justice. As an alternative to Kymlicka’s argument, (...) Quong offers his own justification of polyethnic rights based on a Rawlsian ideal of fair equality of opportunity. I defend luck egalitarianism against Quong’s objection arguing that if choice ever matters, it matters in relation to cultural disadvantages too. Also, the Rawlsian ideal of fair equality of opportunity cannot justify the sort of polyethnic rights that Quong wants it to justify, once we set aside an unwarranted statist focus in Quong’s conception of fair equality of opportunity. Whatever the weaknesses of luck egalitarianism are, the inadequacy of the position in relation to accommodating cultural disadvantages of immigrants is not among them. (shrink)

This paper describes the Danish legal framework for district cooling as an example of a model which so far has had limited success. A number of suggestions are analysed and discussed.

Discrimination laws usually prohibit discrimination based on some traits, like race, caste, and sex, and not on others, like sports team allegiance. Should socioeconomic class be included among the protected traits? We examine an argument for the view that it should which leads to the conclusion that both direct and indirect socioeconomic discrimination should be prohibited by the state. The argument has three premises: (1) direct paradigmatic discrimination should be prohibited by law; (2) if direct paradigmatic discrimination should be prohibited (...) by law, then so should direct socioeconomic discrimination; and (3) where direct discrimination based on a certain trait should be prohibited by law, so should indirect discrimination on the basis of the same trait. Since we assume most readers will accept (1), the paper is largely devoted to the defense of (2) and (3). The outlawing of direct socioeconomic discrimination would involve an adjustment of the political and legal status quo, but we argue that it should nevertheless be implemented. By contrast, a prohibition on indirect socioeconomic discrimination would require a radical change to the way in which our societies are structured, because many of our laws, policies, and practices systematically (re)produce inequality to the disproportionate detriment of the poor. Our main aim, therefore, is not to defend the prohibition of indirect socioeconomic discrimination, but to show that most people’s views about discrimination are in deep tension with their attitude to current law. Resolving this tension would require for most of us to revise our beliefs either about whether indirect socioeconomic discrimination should be prohibited or about (1)–(3). One might reject the view that law should prohibit socioeconomic discrimination and still accept this claim about a deep tension in most people’s views on discrimination. (shrink)

Dennis Whitcomb argues that there is no God on the grounds that God is supposed to be omniscient, yet nothing could be omniscient due to the nature of grounding. We give a formally identical argument that concludes that one of the present co-authors does not exist. Since he does exist, Whitcomb’s argument is unsound. But why is it unsound? That is a difficult question. We venture two answers. First, one of the grounding principles that the argument relies on is false. (...) Second, the argument equivocates between two kinds of grounding: instance-grounding and quasi-mereological grounding. Happily, the equivocation can be avoided; unhappily, avoidance comes at the price of a false premise. (shrink)

In presenting the key theoretical notions in Jacobi’s philosophical work, this paper shows how these notions are operative in Schellings late philosophy and in Kierkegaard. It is argued that Jacobi’s criticism of Spinozist rationalism is echoed in Schelling’s and Kierkegaard’s criticism of Hegelian speculation as it is shown that Jacobi’s distinction between two different kinds of knowledge, i.e. demonstration and illumination, is also at the very heart of Schelling’s and Kierkegaard’s philosophy. On this background the article finally discusses some important (...) similarities between Schelling and Kierkegaard, stressing the importance of the concept of the will as well as the relation between negativity and positivity. (shrink)

The paper reveals some connections between the epistemological and anthropological aspects of Kierkegaard's notion of negativity, thereby putting the concepts of necessity and freedom into focus. Thus different notions of subjectivity are taken up for discussion, on the one hand, subjectivity as certainty and, on the other hand, a dialectical understanding of the self. Regarding the notions of necessity and freedom as well as the different theories of subjectivity. I relate Kierkegaard to philosophers within the German idealism, that is, Fichte (...) and Schelling, especially pointing to some crucial similarities between the philosophy and theology of Schelling and Kierkegaard.

I have been experimenting with meditation for a long time, but just recently I seem to have come across another being in there. It may just be me looking at me, but whatever it is, it is showing me some really interesting arrangements of colored balls. At first, I thought it was just random colors and shapes, but it became very ordered. It was like this being (me?) was trying to talk to me but couldn’t, so was showing me some (...) math in pictures. I have gone in many times now and am trying to write things down here. Has anyone else ever seen this? My best guess so far is he is showing me a machine that might be useful to rapidly factor integers. I detail this in the analysis below. There is a lot of extra structure that I am currently disregarding, but is probably also something interesting. I will report more when I know more. (shrink)

Toni Rønnow-Rasmussen | : This paper explores a novel metaethical theory according to which value judgments express conditional beliefs held by those who make them. Each value judgment expresses the belief that something is the case on condition that something else is the case. The paper aims to reach a better understanding of this view and to highlight some of the challenges that lie ahead. The most pressing of these revolves around the correct understanding of the nature of the (...) relevant cognitive attitudes. It is suggested that the distinction between “dormant attitudes” and “occurrent attitudes” helps us to understand these conditional beliefs. | : Cet article explore une nouvelle théorie méta-éthique selon laquelle les jugements de valeur expriment les croyances conditionnelles des sujets qui les font.

The endeavour to locate value in moral progress faces various substantive as well as more formal challenges. This paper focuses on challenges of the latter kind. After some preliminaries, Section 3 introduces two general kinds of “evaluative moral progress-claims”, and outlines a possible novel analysis of a descriptive notion of moral progress. While Section 4 discusses certain logical features of betterness in light of recent work in value theory which are pertinent to the notion of moral progress, Sections 5 and (...) 6 outline the ambiguous character of “making moral progress”.

In this brief review it is not possible to do full justice to this lively and lucidly presented study. It is fair to say, I think, that the considerable merits of this work rest primarily with its intelligent and reliable selection of material, most of which is already available and familiar. This study does not aim to challenge any orthodoxies or present new material of some significant kind. Rasmussen does not need to do this since his real concern is (...) to tell a story about two great thinkers in an engaging manner – a task which he achieves with great success. This is a book that scholars will thoroughly enjoy and appreciate and which will also find many appreciative readers well beyond these boundaries. (shrink)

Employers sometimes use personality tests in hiring or specifically look for candidates with certain personality traits such as being social, outgoing, active, and extraverted. Therefore, they hire based on personality, specifically extraversion in part at least. The question arises whether this practice is morally permissible. We argue that, in a range of cases, it is not. The common belief is that, generally, it is not permissible to hire based on sex or race, and the wrongness of such hiring practices is (...) based on two widely accepted principles: the Relevance Principle and the Fairness Principle. The Relevance Principle states that hiring should be based on what is relevant to job performance, while the Fairness Principle states that hiring should be based on features that individuals can control. Since hiring based on sex or race violates these principles, it is wrong. However, we argue that, in a range of cases, hiring based on extraversion also violates these principles, and assuming the validity of the Relevance and the Fairness Principles, it follows that personality discrimination is morally wrong in those cases.

A well-known problem for preference-utilitarianism is to what extent it should exclude from consideration certain preferences. In this paper I focus on past preferences. I outline three general and some particular positions that a preference-utilitarian reasonably would want to take with regard to past preferences and why I think that endorsing each of these positions create new problems for the preference-utilitarian. At the end I sketch on a possible solution to the axiological problems here presented. However, although the pluralistic approach (...) that I outline shares with preference-utilitarianism the idea that what is valuable is the satisfaction of preferences, it is not a viable option for a utilitarian. My conclusion is therefore that preference-utilitarianism faces a serious axilogical problem. (shrink)

Five arguments are presented in favour of the proposal that people who opt in as organ donors should receive a tax break. These arguments appeal to welfare, autonomy, fairness, distributive justice and self-ownership, respectively. Eight worries about the proposal are considered in this paper. These objections focus upon no-effect and counter-productiveness, the Titmuss concern about social meaning, exploitation of the poor, commodification, inequality and unequal status, the notion that there are better alternatives, unacceptable expense, and concerns about the veto of (...) relatives. The paper argues that none of the objections to the proposal is very telling. (shrink)

Herjeet Kaur Marway recently proposed the Principle of Procreative Justice, which says that reproducers have a strong moral obligation to avoid completing race and colour injustices through their selection choices. In this article, we analyze this principle and argue, appealing to a series of counterexamples, that some of the implications of Marway's Principle of Procreative Justice are difficult to accept. This casts doubt on whether the principle should be adopted. Also, we show that there are some more principled worries regarding (...) Marway's idea of a strong pro tanto duty not to complete injustices through one's procreative choices. Nonetheless, we believe Marway's arguments point in the right general direction regarding duties and structural injustice. Thus, in the final part, we suggest a positive proposal on how it would be possible to respond to the cases we raise. More specifically, we explore the suggestion that agents have a pro tanto duty to participate in eliminating structural injustice. Importantly, this duty can be satisfied, not only in procreation choices but in multiple ways. (shrink)

On 24 July 2022, the landmark decision Roe v. Wade (1973), that secured a right to abortion for decades, was overruled by the US Supreme Court. The Court decision in Dobbs v. Jackson Women’s Health Organisation severely restricts access to legal abortion care in the USA, since it will give the states the power to ban abortion. It has been claimed that overruling Roe will have disproportionate impacts on women of color and that restricting access to abortion contributes to or (...) amounts to structural racism. In this paper, we consider whether restricting abortion access as a consequence of overruling Roe could be understood as discrimination against women of color (and women in general). We argue that banning abortion is indirectly discriminatory against women of color and directly (but neither indirectly, nor structurally) discriminatory against women in general. (shrink)

Overview of the global warming/climate change debate.

Within the literature in green political theory on global environmental threats one can often find dissatisfaction with liberal theories of justice. This is true even though liberal cosmopolitans regularly point to global environmental problems as one reason for expanding the scope of justice beyond the territorial limits of the state. One of the causes for scepticism towards liberal approaches is that many of the most notable anti-cosmopolitan theories are also advanced by liberals. In this paper, I first explain why one (...) of the strongest expressions of liberal anti-cosmopolitanism cannot simply be dismissed because it may fail to support desired environmental ends. The political conception of justice represents one of the most important challenges to cosmopolitanism generally and is thus a serious challenge to viewing global environmental problems in terms of cosmopolitan justice. Second, I will show through the case of anthropogenic global warming that the political conception of justice under current conditions does have clear cosmopolitan implications despite its proponents' claims.

Compelling research in international relations and international political economy on global warming suggests that one part of any meaningful effort to radically reverse current trends of increasing green house gas (GHG) emissions is shared policies among states that generate costs for such emissions in many if not most of the world’s regions. Effectively employing such policies involves gaining much more extensive global commitments and developing much stronger compliance mechanism than those currently found in the Kyoto Protocol. In other words, (...) global warming raises the prospect that we need a global form of political authority that could coordinate the actions of states in order to address this environmental threat. This in turn suggests that any serious effort to mitigate climate change will entail new limits on the sovereignty of states. In this book I focus on the normative question of whether or not we have clear moral reasons to bind ourselves together in such a supranational form of political association. I argue that one can employ familiar liberal arguments for the moral legitimacy of political order at the state level to show that we do have a duty to support such a global political project. Even if one adopts the premises employed by the most influential forms of liberal scepticism to the ideas of global political and distributive justice, such as those advanced by John Rawls and Thomas Nagel, it is clear that the threat of global warming has expanded the scope of justice. We now have a global and demanding duty of justice to create the political conditions that would allow us to collectively address our impact on the Earth’s atmosphere. (shrink)

Giving money to others feels good. It is now standard to use the label ‘warm glow feelings’ to refer to the pleasure people take from giving. But what exactly are warm glow feelings? And why do people experience them? To answer these questions, we ran two studies: a recall task in which participants were asked to remember a donation they made, and a donation task in which participants were given the opportunity to make a donation before reporting their affective states. (...) Correlational and experimental results converge towards the conclusion that, if the nature of the warm glow is straightforward, its source is multifaceted. Regarding the nature of the ‘warm glow’, the pleasure people took in giving was mainly predicted by one particular type of positive emotion and was indeed described by participants as ‘warm’. Regarding the underlying psychological mechanisms, warm glow feelings were elicited by positive appraisals regarding the donor’s moral character, positive appraisals regarding the actual impact of the donor’s donation on the welfare of others and a feeling of communion with others. We discuss the theoretical implications of our findings. (shrink)

The central focus of this paper is the disjunction between the findings of climate science in revealing the threat of global warming and the failure to act appropriately to these warnings. The development of climate science can be illuminated through the perspective provided by Peircian semiotics, but efforts to account for its success as a science and its failure to convince people to act accordingly indicate the need to supplement Peirce’s ideas. The more significant gaps, it is argued, call (...) for the integration of major new ideas. It will be argued that Peirce should be viewed as a Schellingian philosopher, and it will then be shown how this facilitates integration into his philosophy of concepts developed by other philosophers and theorists within this tradition. In particular, Bourdieu’s concepts of the ‘habitus’ and ‘field’ will be integrated with Peirce’s semiotics and used to analyse the achievements and failures of climate science. It will be suggested that the resulting synthesis can augment Peirce’s evolutionary cosmology and so provide a better basis for comprehending and responding to the situation within which we find ourselves.

This chapter constructs the argument that corporate and political policies known to accelerate anthropogenic global warming, and subsequent climate change, constitute crimes against humanity—predicated on failures to avoid reasonably foreseeable threats to sustained human existence. Given the moral gravity of crimes against humanity it follows that financial divestment is ethically obligatory for institutions wishing to avoid moral association. The moral case for fossil fuel divestment, in the wake of such crimes, derives from (a) the ethical implications of negative responsibility, (...) or what constitutes culpability by omission; (b) institutional collaboration based upon immediate financial interests tied to climate inaction; and (c) institutional complicity derived from financial support of corporate behaviors that hasten global warming. Possible objections are examined and refuted. (shrink)

Rønnow-Rasmussen’s book explores the distinction between two kinds of value: good, and good-for. Rønnow-Rasmussen provides a reductive theory of both kinds of goodness: a fitting attitude account of goodness, on which facts about value reduce to facts about the norms governing agents’ attitudes. But Rønnow-Rasmussen argues that they conflict in an especially sharp way, so that we have a kind of choice about which to prioritise, and no obvious grounds on which to choose one over the other. (...) I articulate some virtues of the book but also doubts about the central thesis. (shrink)

Principles of justice, David Estlund argues, cannot be falsified by people’s unwillingness to satisfy them. In his Utopophobia, Estlund rejects the view that justice must bend to human motivation to deliver practical implications for how institutions ought to function. In this paper, I argue that a substantive argument against such bending of justice principles must challenge the reasons for making these principles sensitive to motivational limitations. Estlund, however, provides no such challenge. His dispute with benders of justice is therefore a (...) verbal one over the true meaning of justice, which need not worry those with the intuition that justice should perform a function that requires bending. By focusing on John Rawls’s reasons for bending his justice principles, I point towards a substantive critique of bent justice. (shrink)

Alexander of Aphrodisias' treatise On Providence presents an argument that global warming is impossible based on the existence of divine providence: this raises the question of the compatibility of theism and environmentalism.

The suggestion that philosophers are responsible for global warming seems, on the face of it, absurd. However, that we might cause global warming has been known for over a century. If we had had in existence a more rigorous kind of academic inquiry devoted to promoting human welfare, giving priority to problems of living, humanity might have become aware of the dangers of global warming long ago, and might have taken steps to meet these dangers decades ago. (...) That we do not have academic inquiry of this type, giving priority to problems of living and able to warn humanity of the impending disaster of global warming, is the result of a philosophical mistake – a mistake about what constitutes rigorous intellectual inquiry. This is a mistake of philosophers. Thus philosophers, in failing to grasp the profound intellectual and humanitarian failings of academia as it is at present organized (the outcome of implementing a seriously defective philosophy of inquiry) can perhaps be said to be responsible for global warming.

The paper argues that Toni Rønnow-Rasmussen’s fitting-attitude analysis of ‘good’ and ‘good for’ allows us to interpret and justify Kant’s Formula of Humanity (FH) in a constructive way. His classification of ‘good’ as a non-relational intrinsic final value and ‘good for’ as a relational extrinsic final value sheds light on two main features of FH, namely that it requires us to display a specific attitude to human beings, while also obligating us to recognize this value in the relational dimension. (...) Based on a reflection of what attitudes toward persons are fitting, we might well come to endorse that persons are “ends in themselves” and merit respect and recognition. I then argue (by way of an ethical reading of Kant’s demand to leave the state of nature and move to a rightful civil condition) that we have, in addition to a fitting attitude, deontic normative reasons (not mere pro tanto reasons) for making this very attitude toward persons the principal standard for our relations to others and to ourselves.

Since the last ice age, when ice enveloped most of the northern continents, the earth has warmed by about five degrees. Within a century, it is likely to warm by another four or five. This revolution in our climate will have immense and mostly harmful effects on the lives of people not yet born. We are inflicting this harm on our descendants by dumping greenhouse gases into the atmosphere. We can mitigate the harm a little by taking measures to control (...) our emissions of these gases, and to adapt to the changes by, for instance, building sea walls around coastlines threatened by rising sea levels. But these measures will be very expensive, and the costs will be born by us, the present generation, whereas the benefits will come to future generations. How much should we sacrifice for the sake of the future? Economists and philosophers have independently worked on the question of our responsibility to future generations. This book brings their work together and applies it to global warming. It suggests a programme for future research on the economic and ethical issues. The book is intended for economists, and for philosophers and other social scientists who have a little knowledge of economic methods. (shrink)

When we look at 800,000 year ice core data CO2 levels since 1950 have risen at a rate of 123-fold faster than the fastest rate in 800,000 years. When we see that this rise is precisely correlated with global carbon emissions the human link to climate change seems certain and any rebuttal becomes ridiculously implausible. The 800,000 year correlation between CO2 and global temperatures seems to be predicting at least 9 degrees C of more warming based on current CO2 (...) levels. (shrink)

In the world of Avatar: The Last Airbender (ATLA) and The Legend of Korra (LOK) —let’s call it the Bending World—some people (“benders”) are endowed with telekinetic superpowers to maneuver surrounding objects without physical interaction, by mentally steering (“bending”) one of the four classical “elements of nature” composing the objects: air, fire, water, and earth. Perhaps, in a world where the fundamental laws of nature are radically different from those of our world, the fundamental conditions and manifestations of politics should (...) be radically different too. That, of course, is not to deny that political bodies familiar to us are depicted in ATLA and LOK: tribes, monarchies, autonomous townships, city-states, loose federations, colonial empires, and democracies. Despite those familiar depictions, however, it’s worth contemplating how the existence of supernatural power might fundamentally alter the norms and rationales of politics—and how it might in turn help us better understand our own political reality.

Lippert-Rasmussen and Petersen discuss my ‘Moral case for legal age change’ in their article ‘Age change, official age and fairness in health’. They argue that in important healthcare settings (such as distributing vital organs for dying patients), the state should treat people on the basis of their chronological age because chronological age is a better proxy for what matters from the point of view of justice than adjusted official age. While adjusted legal age should not be used in deciding (...) who gets scarce vital organs, I remind the readers that using chronological age as a proxy is problematic as well. Using age as a proxy could give wrong results and it is better, if possible, for states to use the vital information directly than use age as a proxy. (shrink)

Personal Values is a delightful and enlightening read. It is teeming with novel insights, ground-breaking distinctions, rich examples, new delineations of the field, refreshing historical reminders, inventive arguments, unprecedented connections, identifications of neglected difficulties, and pioneering proposals. I shall focus here on three of these insights, which are illustrative of the pervasive scrupulousness and inventiveness of the book. The first is that there is a distinction between the supervenience base of values and their constitutive grounds. The second is that FA (...) is admittedly circular (because pro-attitudes have values as formal objects), but that this circularity is benign. The third proposal is that one important kind of for- someome-sake’s attitude⎯prototypically, love⎯is such that it is not justified by the properties it represents its object as exemplifying. This is a small sample of claims not meant to be representative of the book. The reason I have chosen to discuss these in particular is that, while finding them plausible and significant, I believe that each raises a worry that Rønnow-Rasmussen fails to address properly. I shall tentatively suggest a possible solution in each case. (shrink)

The idea of geoengineering, or the intentional modification of the Earth's atmosphere to reverse the global warming trend, has entered a working theory stage, finding expression in a variety of proposed projects, such as launching reflective materials into the Earth's atmosphere, positioning sunshades over the planet's surface, depositing iron filings into the oceans to encourage phytoplankton blooms, and planting more trees, to name only a few.

Humanity may underestimate the rate of natural global catastrophes because of the survival bias (“anthropic shadow”). But the resulting reduction of the Earth’s future habitability duration is not very large in most plausible cases (1-2 orders of magnitude) and thus it looks like we still have at least millions of years. However, anthropic shadow implies anthropic fragility: we are more likely to live in a world where a sterilizing catastrophe is long overdue and could be triggered by unexpectedly small human (...) actions. In the same way, an over-inflated toy balloon, which will soon burst, is very fragile. Anthropic fragility can manifest itself in the higher chances of runaway global warming. It has often been suggested that the Earth's atmosphere remained life-supporting for billions of years by sheer chance. Therefore, the survival bias can be strong. It is also known that Earth-like water worlds could experience transitions into deadly moisture greenhouse (mean T = 65C). This means that relatively small anthropogenic actions could put the climate above an unpredictable tipping point, which could lead to the moisture greenhouse. Thus, it is necessary to carry out urgent geoengineering studies and prepare to prevent an unexpected climate catastrophe. There are three main counterarguments against the existence of the anthropic shadow: self-indication assumption (SIA), past observers and the Gaia hypothesis; we show that they fail. It was proposed that SIA exactly compensates the anthropic shadow as an observer unlikely to find herself in a world with a strong anthropic shadow; however, there is a baseline level of the anthropic shadow for all habitable planets, similar to the rate of evolutionary transitions like abiogenesis. There are no “past observers” as qualified observers appeared only 50 years ago. Gaia hypothesis assumes existence of self-stabilizing feedback in climate, but new types of events like quick CO2 growth could override its coping ability. We present a list of other catastrophes that may have been underestimated because of the anthropic shadow, including collider catastrophes, nuclear war and even an alien invasion. We also hypothesized that human intelligence is more likely to emerge in an unstable world that is nearing its end and thus we get a new form of Doomsday argument. (shrink)

The problem of global warming and its implications on the continuous existence of the world are alarming. Hence, the phenomenon has attracted a lot of responses from different people including scholars, journalists and religious leaders. While researches on possible solutions to the menace of global warming continue, the contribution of this paper is that a combination of traditional African attitude to nature and Christian theology of environment can be used as a model for the control of global (...) class='Hi'>warming. Important elements in the two traditions include the idea of relationship between God, human and nature and the eschatological views of the two traditions. The paper concludes that the combination of these views will help to check human attitude to nature and unbridled craze for material wealth which are the major causes of global warming. (shrink)
