The Procreation Asymmetry, in strongest form, states (roughly) that while we have no reason to create happy people, we do have reason not to create unhappy people. Despite its popularity among non-utilitarian philosophers, it has been surprisingly difficult to give an adequate theoretical defense of this asymmetry. However, in a recent paper, Johann Frick attempts to provide a unified account of the asymmetry that avoids the problems with previous attempts. One of Frick’s novel claims is that a certain wide-scope conditional reasons principle, together with two plausible inference rules, serves to capture both conjuncts of the asymmetry. We argue that while Frick’s account is more plausible than previous accounts, it can explain the asymmetry only by appealing to a unexplained further asymmetry that in effect reaffirms the asymmetry, and that the wide-scope conditional reasons principle does not help to provide a satisfactory explanation of the asymmetry.

This handbook presents up-to-date theoretical analyses of problems associated with the moral standing of future people in current decision-making. Future people pose an especially hard problem for our current decision-making, since their number and their identities are not fixed but depend on the choices the present generation makes. Do we make the world better by creating more people with good lives? What do we owe future generations in terms of justice? Such questions are not only philosophically difficult and important, but also directly relevant to many practical decisions and policy issues, including on climate, health, population control and taxation. If we are to adequately assess such issues, we must be able to determine the value of differently sized populations. The aim of this handbook is to shed light on the value of population change and the nature of our obligations to future generations, and to offer practical guidance to policy-makers as to how our duties to future generations should be discharged. It contains an extensive and accessible introduction for those unfamiliar with the topic of population ethics as well as original work from key figures in academic debates on population ethics covering three main themes: ways out of the paradoxes of population ethics, questioning some philosophical and methodological assumptions underlying these paradoxes, and several applications of population ethics to real world issues.

All else being equal, creating a miserable person makes the world worse, and creating an ecstatic person makes it better. Such claims are easily justified if it can be better, or worse, for a person to exist than not to exist. But that seems to require that things can be better, or worse, for a person even in a world in which she does not exist. Ingmar Persson defends this seemingly paradoxical claim in his latest book, Inclusive Ethics. He argues that persons that never exist are merely possible beings for whom non-existence is worse than existence with a good life. We argue that Persson's argument, as stated in his book, has false premises and is invalid. We reconstruct the argument to make it valid, but the premises remain highly problematic. Finally, we argue, one can make sense of our procreative obligations without letting merely possible beings into the moral club.

According to doxastic normativism, belief is essentially governed by a norm of correctness, which states, ‘Your belief that is correct if and only if is true’. The normativist further holds that this condition of correctness has normative import, meaning that it entails claims about what one ought to believe. Bykvist and Hattiangadi argue that at least one of these two claims made by the normativist is false; that is to say, having truth as its condition of correctness is either not constitutive of belief, or does not have normative import. They argue that ‘correct’ is not an essentially normative term, and that the purported norm of truth fails to distinguish belief from other propositional attitudes. Moreover, no version of normativism can avoid the unacceptable implication that we ought to believe blindspot propositions, which are true but nevertheless could not be truly believed.

This chapter discusses the question of whether we can make it better for a person by creating her. It argues that John Broome’s argument for a negative answer to this question can be improved upon to avoid some recent criticisms. Instead of being concerned with whether a state of affairs that is better for you _would_ be better for you if it obtained, we should ask whether it _could_ make things better for you. It is also shown that these criticisms assume a mistaken idea about what it means to say that abstract states of affairs have value. The correct idea is that valuable states of affairs are possible value-makers of the world.

This chapter argues that collectivist duties do not significantly affect our individual obligations in certain important coordination problems. These are moral high stake versions of the so-called Hi-Lo cases. This also means that the conflict between collectivists and individualists, who resist the collectivist move, is not that stark in these cases. Along the way, I will also show that Hi-Lo cases are of interest to all kinds of moral theories, not just consequentialism, for which it is usually seen as a challenge.

We present an argument about the methodology of ethics, broadly conceived, drawing on recent research on modelling in the philosophy of science. More specifically, we argue that normative ethics should adopt the methodology of modelling. We make our case in two parts. First, despite the perhaps unfamiliar terminology, modelling already happens in ethics. We identify it, and argue that its practice could be improved by recognising that it is modelling and by adopting some methodological lessons from philosophy of science. Second, modelling should be adopted more widely within normative ethics, because it fits well with various methodological ends we shall identify. Models can be used to investigate ethical questions in a manner that is systematic but relatively free of foundational theoretical commitments in first-order ethics. Models are more local, and less ambitious, than theories. They can be used to break deadlocks, by focusing attention on the particularities of a sub-domain and by providing a common tool–the surrogate model system–which each side can use to make their principles precise, illustrate the implications of their view, and identify sources of disagreement or points of agreement. We are pluralists about method, so this is not a call to abandon other philosophical methods. It is simply a plea for modelling, motivated by the method’s independent benefits and its fruitfulness in resolving some persistent methodological problems in ethics.

This chapter discusses time and value. The two main questions are: What is the time of value? and What is the value of time? The first main question splits into two: Does what has value always have a temporal location? and Does value itself have temporal location? The second main question asks whether temporal features are evaluatively relevant. The features discussed are duration, temporal order, life-periods, and tense. The kinds of value in focus are well-being, intrinsic value, final value, virtues, and moral value of persons.

L. A. Paul has recently argued that the epistemically transformative nature of certain experiences makes it impossible to rationally decide whether to have the experience or not. We start by explaining why, contrary to what Paul claims, epistemically transformative experiences do not pose a general problem for the possibility of rational choice. However, we show there is a particular type of agent for whom the problem identified by Paul does arise. With this agent in mind, we examine Paul’s own suggestion for how to approach a transformative decision problem, namely, that one should decide based on whether one would like to come to know the experience in question, and we conclude that Paul’s suggestion is no solution for this particular agent. In other words, Paul’s solution does not work for the only type of agent for whom the problem she has identified arises.

Among health economists, who think that preferences are the correct standard of the value of health states, it is common to assume, at least implicitly, that the correct criterion of this value takes the following schematic form: H1 is a better health state than H2 iff the members of group S prefer (on average) being in H1 to being in H2. Various candidates for members of S have been proposed, including medical experts, the general public, H1-patients, H2-patients, former H1-patients, former H2-patients, or combinations of these groups. I shall argue that criteria of this form run into serious problems, if we consider cases where people’s fundamental preferences change from one health state to another. I shall also show that these problems afflict hybrid views, according to which preferences are only one determinant of the value of health, the objective value of health states being another. Finally, I shall argue that a better subjectivist criterion would be something like this: H1 is a better health state than H2 iff the H1-patients would want to be in H1 more than the H2-patients would want to be in H2. According to this criterion, the value of a health state is determined by the absolute attitudes (favouring, disfavouring, neutrality) people would have towards a health state were they to be in it. Along the way, I will also present and make use of an attitude matrix framework that enables us to represent in a simple way complex information about attitudes. With this framework at hand, we can easily see the advantages and disadvantages of different subjectivist accounts of the value of health.

Time is morally relevant. This chapter considers three temporal features that could be assigned moral significance when one assesses actions, activities, character‐traits, and events: life periods, temporal order, and tense. It seems plausible to assign significance to life periods when one assesses character traits – innocence is a virtue for children but not for adults, for example. It is also clear that the temporal order between events can have moral significance when one assesses the overall value of the sequence of events. When it comes to tense‐partiality it is clear that people often show a psychological bias towards the future. But, it is very doubtful that this bias can be upgraded to an acceptable tense‐partial moral theory. First, such a theory will have many counterintuitive implications. Second, it will be difficult to consistently act on such a theory in dynamic choice situations.

Just as we can be more or less certain that there is extraterrestrial life or that Goldbach’s conjecture is correct, we can be more or less certain about normative matters, such as whether euthanasia is permissible or whether utilitarianism is true. However, accommodating the phenomenon of degrees of normative certitude is a difficult challenge for non-cognitivist and expressivist views, according to which normative judgements are desire-like attitudes rather than beliefs. Several attempts have been made on behalf of non-cognitivism and expressivism to meet the challenge Studies in metaethics, Oxford University Press, Oxford, 2007; Sepielli in Philos Stud 160: 191–207, 2012; Eriksson and Francén Olinder in Aust J Philos 94: 719–735, 2016). These attempts have all been found wanting. Michael Ridge has recently offered a quasi-realist solution, according to which expressivists can say exactly what cognitivists say about certitude, including normative certitude. In this paper, we explain the basic problem and Ridge’s quasi-realist solution. We then argue that the quasi-realist account of normative certitude faces severe difficulties that do not arise for cognitivist accounts, according to which normative judgements are beliefs.

According to the popular fitting attitude analysis of value, to be good is to be the object of a proattitude that it is fitting, in some sense, to have. One version of this analysis can be traced back to Franz Brentano, according to which “good” means “worthy of love.” In a review in Ethics of Brentano's The Origin of the Knowledge of Right and Wrong, G. E. Moore accuses Brentano of committing a fallacious inference, which I will call “Brentano's fallacy.” I shall show that Moore's accusation, properly formulated, hits the target and that his argument can be generalized so that it undermines other Brentano-like versions of the fitting attitude analysis.

Pandemics and other similar crises force us to make difficult moral trade-offs. It is tempting to think that this challenge should be met by invoking fundamental moral principles. This is a mistake. Instead, we need to work hard at designing institutions that enable the officeholders to make reasonable decisions under both fundamental ethical disagreement and empirical/evaluative uncertainty. It is argued that this is best done by supplementing the ethical-cum-legal platforms already in use with an ethical framework inspired by social welfare theory.

The fact that our attitudes change poses well-known challenges for attitude-sensitive wellbeing theories. Suppose that in the past you favoured your adventurous youthful life more than the quiet and unassuming life you expected to live as an old person; now when you look back you favour your current life more than your youthful past life. Which period of your life is better for you? More generally, how can we find a stable attitude-sensitive standard of wellbeing, if the standard is in part defined in terms of unstable attitudes? In this paper, I introduce an ‘attitudinal matrix’ framework that will help us clear up the problems posed by changing attitudes across time. In particular, it will help us see what is at stake, which principles that can or cannot be combined, and what might be the best solution. I defend a very plausible candidate constraint on a solution to the challenge of changing attitudes, which I call ‘diagonalism’. It is argued that among the three main forms of substantive attitude-sensitive wellbeing theories – the attitude-version, the object-version, and the satisfaction-version – it is the satisfaction-version that can both satisfy diagonalism and provide the best account of temporal and lifetime wellbeing.

ABSTRACT Broome’s target in his paper is the popular claim that rationality consists in responding correctly to reasons. He takes this to be the reductive claim that rationality reduces to responding correctly to reasons, which in turn he takes to entail that the property of rationality is identical to the property of responding correctly to reasons. It is this identity claim that Broome attempts to refute by showing that the properties that are supposed to be identical cannot be so because they themselves do not share all properties. In this short commentary, I shall say something about the overall structure of Broome’s argument. More specifically, I shall argue that in its current form his argument rests on a very controversial premise, but that it can be replaced with an argument that avoids it and has wider significance. I shall also question the way Broome deals with the so-called Kantian argument against his own argument. Finally, I shall sketch an alternative view of rationality, which agrees with Broome that it supervenes on the mind, but disagrees with him on the question of whether it itself is a purely mental property.

Recently, there has been a revival in taking empirical magnitudes seriously. Weights, heights, velocities and the like have been accepted as abstract entities in their own right rather than just equivalence classes of objects. The aim of my paper is to show that this revival should include value magnitudes. If we posit such magnitudes, important value comparisons can be easily explained; it becomes easier to satisfy the axioms for measurement of value; goodness, badness, and neutrality can be given univocal definitions; value aggregation can be given a non-mathematical understanding which allows for Moorean organic unities. Of course, this does not come for free. One has to accept a rich ontology of abstract value magnitudes, but, to quote David Lewis, ‘The price is right; the benefits in theoretical unity and economy are well worth the entities.’

: This paper focuses on cases of epistemically transformative experiences, as Paul calls them, cases where we have radically different experiences that teach us something we would not have learned otherwise. Paul raises the new and rather intriguing question of whether epistemic transformative experiences pose a general problem for the very possibility of rational decision-making. It is argued that there is an important grain of truth in Paul’s set up and solution when it is applied to a certain narrowly defined set of cases – choices to have a new taste experience in a safe environment, where no important objective values are at stake. But the way she generalizes this approach to large-scale life choices, such as the choice to become a parent, is less convincing. Furthermore, given a proper understanding of revelatory value, there is no need to reconfigure the agent’s choice situation in order to enable rational decision-making. Keywords: Transformative Experience; Rational Decision-Making; Revelatory Value; Subjective Value La riconfigurazione dei problemi decisionali nell’ottica di Transformative Experiences di L.A. Paul Riassunto: Questo lavoro si concentra sui casi di esperienze epistemicamente trasformative, come le definisce Paul, casi in cui abbiamo esperienze radicalmente differenti che ci insegnano qualcosa che non avremmo appreso diversamente. Paul solleva una questione nuova e alquanto intrigante, ossia se le esperienze epistemicamente trasformative pongano un problema generale per l’effettiva possibilità della decisione razionale. Si sosterrà come vi sia un importante elemento di verità nella posizione e nella soluzione di Paul, se riferite a un ristretto numero di casi – la scelta di provare una nuova esperienza in un ambiente sicuro, dove non sono in gioco valori oggettivamente importanti. E, tuttavia, il modo in cui Paul generalizza questo approccio investendo un vasto ambito di scelte di vita, quali la scelta di diventare genitore, è meno convincente. Inoltre, data un’adeguata comprensione di valori rivelativi, non c’è bisogno di riconfigurare il contesto di scelta dell’agente per attivare un processo decisionale razionale. Parole chiave: Esperienza trasformativa; Decisione razionale; Valore rivelativo; Valore soggettivo.

The long sweep of human history has involved a continuing interaction between peoples' efforts to improve their well-being and the environment's stability to sustain those efforts. Throughout most of that history, the interactions between human development and the environment have been relatively simple and local affairs. But the complexity and scale of those interactions are increasing. What were once local incidents of pollution shared throughout a common watershed or air basin now involve multile nations - witness the concerns for acid desposition in Europe and North America. What were once acute episodes of relatively reversible damage now affect multiple generations - witness the debates over disposal of chemical and radioactive wastes.
