John Harris has previously proposed that there is a moral duty to participate in scientific research. This concept has recently been challenged by Iain Brassington, who asserts that the principles cited by Harris in support of the duty to research fail to establish its existence. In this paper we address these criticisms and provide new arguments for the existence of a moral obligation to research participation. This obligation, we argue, arises from two separate but related principles. The principle of fairness (...) obliges us to support the social institutions which sustain us, of which research is one; while the principle of beneficence, or the duty of rescue, imposes upon us a duty to prevent harm to others, including by supporting potentially beneficial, even life-saving research. We argue that both these lines of argument support the duty to research, and explore further aspects of this duty, such as to whom it is owed and how it might be discharged. (shrink)

This paper draws on the 'Fitting Attitudes' analysis of value to argue that we should take the concept of fittingness (rather than value) as our normative primitive. I will argue that the fittingness framework enhances the clarity and expressive power of our normative theorising. Along the way, we will see how the fittingness framework illuminates our understanding of various moral theories, and why it casts doubt on the Global Consequentialist idea that acts and (say) eye colours are normatively on a (...) par. We will see why even consequentialists, in taking rightness to be in some sense determined by goodness, should not think that rightness is conceptually reducible to goodness. Finally, I will use the fittingness framework to explicate the distinction between consequentialist and deontological theories, with particular attention to the contentious case of Rule Consequentialism.

Balfe argues against enhanced interrogation. He particularly focuses on the involvement of U.S. healthcare professionals in enhanced interrogation. He identifies several empirical and normative factors and argues that they are not good reasons to morally justify enhanced interrogation. I argue that his argument can be improved by making two points. First, Balfe considers the reasoning of those healthcare professionals as utilitarian. However, careful consideration of their ideas reveals that their reasoning is consequential rather than utilitarian evaluation. Second, torture is a (...) serious human rights abuse. When healthcare professionals become involved in enhanced interrogation, they violate not only human rights against torture but also human rights to health. Considering the consequential reasoning against human rights abuses, healthcare professionals’ involvement in enhanced interrogation is not morally justified. Supplementing Balfe’s position with these two points makes his argument more complete and convincing, and hence it can contribute to the way which shows that enhanced interrogation is not justified by consequential evaluation.

Chamberlin insists on its validity in contributing to our thinking about the place of ethics in international affairs and in clarifying both the dangers and potential areas of cooperation inherent in many international relationships.

Here is a tribute to humanity. When under dictatorial rule, with free speech much constrained, a young intellectual mimed; he mimed in a public square. He mimed a protest speech, a speech without words. People drew round to watch and listen; to watch the expressive gestures, the flicker of tongue, the mouthing lips; to listen to – silence. The authorities also watched and listened, but did nothing.

This paper explores the ethics of introducing genome-editing technologies as a new reproductive option. In particular, it focuses on whether genome editing can be considered a morally valuable alternative to preimplantation genetic diagnosis. Two arguments against the use of genome editing in reproduction are analysed, namely safety concerns and germline modification. These arguments are then contrasted with arguments in favour of genome editing, in particular with the argument of the child’s welfare and the argument of parental reproductive autonomy. In addition (...) to these two arguments, genome editing could be considered as a worthy alternative to PGD as it may not be subjected to some of the moral critiques moved against this technology. Even if these arguments offer sound reasons in favour of introducing genome editing as a new reproductive option, I conclude that these benefits should be balanced against other considerations. More specifically, I maintain that concerns regarding the equality of access to assisted reproduction and the allocation of scarce resources should be addressed prior to the adoption of genome editing as a new reproductive option.

Are there any conditions under which to justify deliberately hiding or manipulating the expression of our opinions, emotions or character traits in front of others? this article examines David Hume’s answer to this question by discussing the practices that he calls good manners and impudence. the conclusion is that Hume’s description of the moral point of view allows for two conditions under which practices of opacity such as good manners and impudence can be morally assessed.

I argue for the existence of a ‘ratcheting-up effect’: the behavior of moral saints serves to increase the level of moral obligation the rest of us face. What we are morally obligated to do is constrained by what it would be reasonable for us to believe we are morally obligated to do. Moral saints provide us with a special kind of evidence that bears on what we can reasonably believe about our obligations. They do this by modeling the level of (...) sacrifice a person can realistically bear. Exposure to moral saints thus ‘ratchets-up’ our obligations by combating a type of ignorance that would otherwise defeat those obligations. (shrink)

The well-being account of sacrifice says that sacrifices are gross losses of well-being. This account is attractive because it explains the relationship between sacrifice and moral obligation. However, sacrifices made on behalf of loved ones may cause trouble for the account. Loving sacrifices occur in a context where the agent’s well-being and the beneficiary’s well-being are intertwined. They present a challenge to individualism about well-being. Drawing inspiration from feminist philosophers and bioethicists, I argue that a notion of ‘relational well-being’, analogous (...) to ‘relational autonomy’, can help account for loving sacrifices without either undermining the well-being theory of sacrifice or minimizing the very real sacrifices made in caregiving situations.

This paper examines the prevalent assumption that when people interact online via proxies—avatars—they encounter each other. Through an exploration of the ontology of users and their avatars we argue that, contrary to the trend within current discussions of interaction online, this cannot be unproblematically assumed. If users could be considered in some sense identical to their avatars, then it would be clear how an encounter with an avatar could ground an encounter with another user. We therefore engage in a systematic (...) investigation of several conceptions of identity, concluding that in none of these senses can users and avatars be identified. We go on to explore how current accounts of identity-as-selfhood online might resolve this problem by appealing to narrativity or authorship, ultimately concluding that as these accounts stand they are unable to provide grounds for the claim that users encounter each other online and so supplementary work is required.

Negative duties are duties not to perform an action, while positive duties are duties to perform an action. This article focuses on the question of who holds the positive duties correlative to human rights. I start by outlining the Universal Scope Thesis, which holds that these duties fall on everyone. In its support, I present an argument by analogy: positive and negative duties correlative to human rights perform the same function; correlative negative duties are generally thought to be universal; by (...) analogy, we have reason to think that positive duties are held by everyone. I then consider three disanalogies that challenge the above argument. To address these worries, I introduce the notion of ‘aggregative duties’ – duties that can only be adequately grasped when we focus on the aggregate effect of the actions and omissions of different agents. This framework allows me to refine the initial thesis and address the objections. (shrink)

Recent developments in biogerontology—the study of the biology of ageing—suggest that it may eventually be possible to intervene in the human ageing process. This, in turn, offers the prospect of significantly postponing the onset of age-related diseases. The biogerontological project, however, has met with strong resistance, especially by deontologists. They consider the act of intervening in the ageing process impermissible on the grounds that it would (most probably) bring about an extended maximum lifespan—a state of affairs that they deem intrinsically (...) bad. In a bid to convince their deontological opponents of the permissibility of this act, proponents of biogerontology invoke an argument which is grounded in the doctrine of double effect. Surprisingly, their argument, which we refer to as the ‘double effect argument’, has gone unnoticed. This article exposes and critically evaluates this ‘double effect argument’. To this end, we first review a series of excerpts from the ethical debate on biogerontology in order to substantiate the presence of double effect reasoning. Next, we attempt to determine the role that the ‘double effect argument’ is meant to fulfil within this debate. Finally, we assess whether the act of intervening in ageing actually can be justified using double effect reasoning. (shrink)

Climate change is projected to have very severe impacts on future generations. Given this, any adequate response to it has to consider the nature of our obligations to future generations. This paper seeks to do that and to relate this to the way that inter-generational justice is often framed by economic analyses of climate change. To do this the paper considers three kinds of considerations that, it has been argued, should guide the kinds of actions that one generation should take (...) if it is to treat both current and future people equitably. In particular it examines the case for what has been termed pure time discounting, growth discounting and opportunity cost discounting; and it assesses their implications for climate policy. It argues that none of these support the claims of those who think they give us reason to delay aggressive mitigation policies. It also finds, however, that the second kind of argument can, in certain circumstances, provide support for passing on some of the costs of mitigation to future generations. (shrink)

Much of ordinary memory is autobiographical; memory of what one saw and did, where and when. It may derive from your own past experiences, or from what other people told you about your past life. It may be phenomenologically rich, redolent of that autumn afternoon so long ago, or a few austere reports of what happened. But all autobiographical memory is first-person memory, stateable using ‘I’. It is a memory you would express by saying, ‘I remember I . . .’.

This paper aims at answering some of the objections to the NIP’s criticism of the idea of rights of future persons. Those objections usually adopt different perspectives depending on how they understand differently the nature of the correlativity between rights and duties – some adopt a present-rights-of-future-persons view, others a future-rights-of-future-persons view, others a transitive present-rights-of-present-persons view, and others still an eternalist view of rights and persons. The paper will try to show that only a non-transitive present-rights-of-present-persons view can survive (...) the challenges posed by the notion of correlativity inherent in the NIP, and thus preserve rights language when discussing the future. This view is proved also more suitable for the legal and political realms, where policies and law-making are usually more concerned with present addressees and short term effects. (shrink)

A theory of intergenerational justice consists in the study of the moral and political status of the relations between present and past or future people, more specifically, of the obligations and entitlements they can potentially generate. The challenges that justify talking about responsibilities between generations are myriad. And the disputes they prompt can focus on the past just as much as on the present, even though the fact that the human species has reached a state of technological progress that enables (...) it to have an irredeemable impact on the planet and perhaps even endanger future human existence tends to make concerns about the future more pressing. Debates on intergenerational justice are twofold. The first revolves around the issue of whether claims of justice across generations whose members' lifetimes do not necessarily overlap could be justified. And the second revolves around the specific conception of justice in play, that is, around the nature of the standard that must be applied as well as around the identification of the contents of the duties that present generations supposedly have vis-à-vis past or future generations. This survey article depicts the conceptual and argumentative framework in which these debates are set. It aims to outline certain of the main features shared by the most influential contemporary theories of intergenerational justice, and the problems inherent in them. It concludes by suggesting that, even though the idea of succeeding generations is merely an abstraction, there are specific empirical states of affairs that require different theoretical responses to intergenerational justice.

Our use of ‘I’, or something like it, is implicated in our self-regarding emotions, in the concern to survive, and so seems basic to ordinary human life. But why does that pattern of use require a referring term? Don't Lichtenberg's formulations show how we could have our ordinary pattern of use here without the first person? I argue that what explains our compulsion to regard the first person as a referring term is our ordinary causal thinking, which requires us to (...) find a persisting object as the mechanism that underpins the causal structure we naturally ascribe to the self. I thus argue against Peacocke's picture (2012), on which it's the cogito that explains one's knowledge of one's own existence. (shrink)

It is widely recognized that lives and activities can be meaningful or meaningless, but few have appreciated that they can also be anti-meaningful. Anti-meaning is the polar opposite of meaning. Our purpose in this essay is to examine the nature and importance of this new and unfamiliar topic. In the first part, we sketch four theories of anti-meaning that correspond to leading theories of meaning. In the second part, we argue that anti-meaning has significance not only for our attempts to (...) theorize about meaning in life, but also for our ability to lead meaningful lives in the modern world.

Here I argue that the hyper-individualistic and rationalistic ethical paradigms – originating in the late eighteenth century and dominating moral philosophy, in various permutations, ever since – cannot capture the moral concerns evoked by the prospect of global climate change. Those paradigms are undone by the temporal and spatial scales of climate change. To press my argument, I deploy two famous philosophical tropes – John Rawls's notion of the original position and Derek Parfit's paradox – and another that promises to (...) become famous: Dale Jamieson's six little ditties about Jack and Jill. I then go on to argue that the spatial and especially the temporal scales of global climate change demand a shift in moral philosophy from a hyper-individualistic ontology to a thoroughly holistic ontology. It also demands a shift from a reason-based to a sentiment-based moral psychology. Holism in environmental ethics is usually coupled with non-anthropocentrism in theories constructed to provide moral considerability for transorganismic entities – such as species, biotic communities, and ecosystems. The spatial and temporal scales of climate, however, render non-anthropocentric environmental ethics otiose, as I more fully explain. Thus the environmental ethic here proposed to meet the moral challenge of global climate change is holistic but anthropocentric. I start with Jamieson's six little ditties about Jack and Jill.

El siguiente trabajo se propone indagar los problemas que la clonación humana acarrearía para la identidad, debido a que este concepto se ha erigido en uno de los principales argumentos para intentar fundamentar una prohibición de la mencionada práctica. Sin embargo, la categoría de identidad aparece no solamente en los argumentos éticos, sino también en las definiciones de la clonación y en las metáforas utilizadas para calificar a los seres nacidos por esta vía. En todos esos planos, se entremezclan diferentes (...) interpretaciones de la idea de identidad, muchas veces creándose confusiones sobre el plano donde se despliegan estos razonamientos. A través de desarrollos filosóficos del concepto, como los aportes de Ricoeur, se pretende evaluar hasta qué punto la identidad del ser nacido por clonación se vería ultrajada por la técnica mencionada.

In his Reasons and Persons, Derek Parfit argues from the possibility of cases of fission and/or fusion of persons that one must reject identity as what matters for personal survival. Instead Parfit concludes that what matters is “psychological connectedness and/or continuity with the right kind of cause,” or what he calls an R-relation. In this paper, I argue that, if one accepts Parfit’s conclusion, one must accept that R-relations are what matter for moral responsibility as well. Unfortunately, it seems that (...) accepting that the R-relation is what matters for both survival and moral responsibility leads to a contradiction. My goal, however, is not merely to point out a problem in Parfit’s account. Instead, I believe that once we understand the basic intuitions which lead to this contradiction, it is clear that there is no fully satisfactory way to account for what matters with respect to survival and moral responsibility.

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. (shrink)

In this paper we discuss an objection to human cloning which appeals to the welfare of the child. This objection varies according to the sort of harm it is expected the clone will suffer. The three formulations of it that we will consider are: 1. Clones will be harmed by the fearful or prejudicial attitudes people may have about or towards them (H1); 2. Clones will be harmed by the demands and expectations of parents or genotype donors (H2); 3. Clones (...) will be harmed by their own awareness of their origins, for example the knowledge that the genetic donor is a stranger (H3). We will show why these three versions of the child welfare objection do not necessarily supply compelling reasons to ban human reproductive cloning. The claim that we will develop and defend in the course of our discussion is that even if it is the case that a cloned child will suffer harms of the type H1-H3, it is none the less permissible to conceive by cloning so long as these cloning-induced welfare deficits are not such as to blight the existence of the resultant child, whoever this may be.

In an influential paper, James Lenman argues that consequentialism can provide no basis for ethical guidance, because we are irredeemably ignorant of most of the consequences of our actions. If our ignorance of distant consequences is great, he says, we can have little reason to recommend one action over another on consequentialist grounds. In this article, I show that for reasons to do with statistical theory, the cluelessness objection is too pessimistic. We have good reason to believe that certain patterns (...) of action will tend to have better consequences, and we have good reason to recommend acting in accordance with strategies based on those advantageous patterns. I close by saying something about the strategies that this argument should lead us to favour. (shrink)

This article compares the ability to track individuals lacking mental states with the ability to track intentional agents. It explains why reference to individuals raises the problem of explaining how cognitive agents track unique individuals and in what sense reference is based on procedures of perceptual-motor and epistemic tracking. We suggest applying the notion of singular-files from theories in perception and semantics to the problem of tracking intentional agents. In order to elucidate the nature of agent-files, three views of the (...) relation between object- and agent-tracking are distinguished: the Independence, Deflationary and Organism-Dependence Views. The correct view is argued to be the latter, which states that perceptual and epistemic tracking of a unique human organism requires tracking both its spatio-temporal object-properties and its agent-properties.

Bishop Butler objected to Locke's theory of personal identity on the grounds that memory presupposes personal identity. Most of those sympathetic with Locke's account have accepted Butler's criticism, and have sought to devise a theory of personal identity in the spirit of Locke's that avoids Butler's circularity objection. John McDowell has argued that even the more recent accounts of personal identity are vulnerable to the kind of objection Butler raised against Locke's own account. I criticize McDowell's stance, drawing on a (...) distinction introduced by Annalisa Coliva between two types of immunity to error through misidentification. (shrink)

Kripke’s argument against functionalism extended to physical computers poses a deep philosophical problem for understanding the standard view of what computers are. The problem puts into jeopardy the definition in the standard view that computers are physical machines for performing physical computations. Indeed, it is entirely possible that, unless this philosophical problem is resolved, we will never have a good understanding of computers and may never know just what they are.

Collective action problems lie behind many core issues in ethics and social philosophy—for example, whether an individual is required to vote, whether it is wrong to consume products that are produced in morally objectionable ways, and many others. In these cases, it matters greatly what we together do, but yet a single individual’s ‘non-cooperative’ choice seems to make no difference to the outcome and also seems to involve no violation of anyone’s rights. Here it is argued that—contrary to influential arguments (...) by Peter Singer, Alastair Norcross, Shelly Kagan, Derek Parfit, and Allan Gibbard—an appeal to the expected consequences of acts cannot deliver plausible verdicts on many of these cases, because individuals often have a probability of making a difference that is sufficiently small to ensure that ‘non-cooperation’ is the option with the greatest expected value, even when consequentialists themselves agree that ‘cooperation’ is required. In addition, an influential argument by Singer, Norcross, and Kagan is shown to be unsound for the claim that in the collective action situations at issue, the expected effect of one individual’s action equals the average effect of everyone’s similar actions. These results have general implications for normative theory, because they undermine the sort of consequentialist explanation of collective action cases that is initially attractive from many theoretical points of view, consequentialist and otherwise.

One of the few things modern liberals, classical liberals, and conservatives can agree on is the charge that some of the worst features oftotalitarian socialist regimes have their origins in the writings of Karl Marx and Friedrich Engels. Nevertheless, the nature of this claim, and therefore the reasons for accepting or rejecting it, are oftenleft obscure. If it is understood simply as a causal statement, then it must be confirmed or disconfirmed by empirical social science. The political philosopher can at (...) most assist by providing a clear characterization of the conceptual content of the beliefs which constitute the independent variable in the alleged causal relation: those beliefs concerning Marx's and Engels's thoughts which are said to have exerted the causal influence in question. Even if empirical research did showthat beliefs about Marxist theory were a significant causal influencein the rise of certain features of totalitarian socialism, this wouldbe of limited philosophical interest if the beliefs in question were misunderstandings of the theory and if the correct explanationof why these misunderstandings occurred appealed to factors external to the theory itself. However, it would be of considerable philosophical interest if correct beliefs about Marxist theory exerted a causalinfluence on some of the more undesirable aspects of totalitarian socialism, or if incorrect beliefs did and the existence of thesemisunderstandings could be traced to ambiguities or gaps in the Marxist theory itself. The political philosopher has a legitimate interestin the relationship between the writings of Marx and Engels on the rise of totalitarian socialism, not because he is interested in articulating and testing causal connections between beliefs and social phenomena in general, but because Marxist theory is supposed – by its authors – to inspire and guide change toward a better society.

This paper addresses the question of whether gathering additional evidence is always rationally required, both from the point of view of instrumental rationality and of epistemic rationality. It is shown that in certain situations, it is not instrumentally rational to look for more evidence before making a decision. These are situations in which the risk of “misleading” evidence – a concept that has both instrumental and epistemic senses – is not offset by the gains from the possibility of non-misleading evidence. (...) These situations also undermine a particular argument for the claim that it is epistemically rational to look for more evidence, though it is argued that the relationship between instrumental and epistemic rationality makes such arguments flawed to begin with. Furthermore, these situations show us that our epistemic and our practical goals sometimes point us in different directions, not merely because of our limited resources or because our desires are sometimes best served by being in particular epistemic states, but because of the nature of rational action.

It is commonly recognized that not all actions are candidates for moral evaluation. For instance, morality is silent on the issue whether to tie one's right shoe before one's left shoe or the other way around. This shoe-tying action is not a candidate for moral appraisal. The matter is amoral, for neither alternative is morally required nor forbidden, and both are permissible. It is not commonly recognized that not all actions are candidates for prudential evaluation. I shall argue, however, that (...) there are cases of individual action over time, as well, that are aprudent in the sense that none of the alternatives under consideration are required or forbidden by prudence, but all of them are permissible. These are cases in which there is no fact of the matter as to what is the best choice for one. There are at least two such cases: first, cases in which the alternative courses of action open to one are incommensurable; and second, cases in which one's values are not yet determined and one is deciding what values to adopt, what sort of person to become, or what ideals to pursue. In these cases, prudence is silent on the question of what one ought to do. Indeed, I go on to argue prudence can even be silent on the question whether to act according to the values one currently holds or to pursue an entirely different course that will result in changes to one's values, which is the third case of aprudent choice.

According to a desire-satisfaction theory of well-being, the satisfaction of one’s desires is what promotes one’s well-being. Against this, it is frequently objected that some desires are beyond the pale of well-being relevance, for example: the desire to count blades of grass, the desire to collect dryer lint and the desire to make handwritten copies of War and Peace, to name a few. I argue that the satisfaction of such desires – I call them “quirky” desires – does indeed contribute (...) to a desirer’s well-being, when (and only when) the desirer is able to provide what Anscombe calls a desirability characterization of the object of the desire. One successfully provides such a characterization when one is able to describe the object of desire in such a way as to make comprehensible to others what she sees as positive, worthy of pursuit, in that object. To make the case, I consider common desires such as the desires to take a walk on the beach, drink a beer or listen to music. I argue that, although the well-being relevance of such common desires normally is not questioned, their satisfactions contribute to well-being just in case the same condition is met. I then argue by analogy with common desires that quirky desires are also relevant to well-being just in case that condition is met. After sketching this solution to the problem of quirky desires, I show that this response is better than other responses that have been given by desire theorists. I then develop several aspects of this account in response to objections that can be raised against it. Among these (to name a few) are the objection that my account does not apply to the well-being of infants and other inarticulate persons; the objection that intrinsic desires, such as for pleasure, cannot be given desirability characterizations; and the objection that desirability characterizations must advert to pleasure or to objectively good properties of the object of desire, so that my account reduces either to hedonism or to an objective view of well-being.

One version of the desire satisfaction theory of well-being (i.e., welfare, or what is good for one) holds that only the satisfaction of one's present desires for present states of affairs can affect one's well-being. So if I desire fame today and become famous tomorrow, my well-being is positively affected onlyif tomorrow, when I am famous, I still desire to be famous. Call this the present desire satisfaction theory of well-being. I argue, contrary to this theory, that the satisfaction of (...) past desires that are no longer held does indeed affect one's well-being. The satisfaction of past desires is good for one in that the present satisfaction of past desires positively affects one's past well-being. I argue for this view in stages, starting with the recognition that many of our desires are satisfied not at an instant but over an interval of time, and that it is during this interval of time that our well-being is positively affected. Once we get our foot in the door with some temporal thickness to desire satisfaction and the associated well-being, I argue, the door must open more widely to allow for greater temporal distance between present desire satisfaction and past well-being. I defend my thesis that present satisfaction of past desires increases one's past welfare against objections, including the claim that it involves backward causation and Velleman's claim that the view is highly counterintuitive whether or not it involves backward causation. I argue that some of the objections rely on hedonistic intuitions, intuitions that most desire satisfaction theories of welfare aim to correct. Once properly understood and applied, my counterintuitive and controversial thesis is really quite innocuous. (shrink)

Williams (1970) argues that our intuitions about personal identity vary depending on how a given thought experiment is framed. Some frames lead us to think that persistence of self requires persistence of one's psychological characteristics; other frames lead us to think that the self persists even after the loss of one's distinctive psychological characteristics. The current paper takes an empirical approach to these issues. We find that framing does affect whether or not people judge that persistence of psychological characteristics is (...) required for persistence of self. Open-ended, abstract questions about what is required for survival tend to elicit responses that appeal to the importance of psychological characteristics. This emphasis on psychological characteristics is largely preserved even when participants are exposed to a concrete case that yields conflicting intuitions over whether memory must be preserved in order for a person to persist. Insofar as our philosophical theory of personal identity should be based on our intuitions, the results provide some support for the view that psychological characteristics really are critical for persistence of self.

In a well-known paper, Bernard Williams argues that an immortal life would not be worth living, for it would necessarily become boring. I examine the implications for the boredom thesis of three human traits that have received insufficient attention in the literature on Williams’ paper. First, human memory decays, so humans would be entertained and driven by things that they experienced long before but had forgotten. Second, even if memory does not decay to the extent necessary to ward off boredom, (...) once-satisfied desires often return after a sufficient period of time. Eternity would always contain sufficient time for our desires to rejuvenate. Third, even if too many of our desires were satisfied but not yet rejuvenated, we can expect that human ingenuity would continue to invent new pursuits, pastimes, careers, and ways of life that would prevent us from becoming bored as we moved from one to another. Finally, I consider and respond to several objections, including the claims that as much variety as I propose to be put into an eternal life is inconsistent with having one character throughout one’s life and that the sort of character change and memory decay I postulate is inconsistent with personal identity.

Moral status ascribes equal obligations and rights to individuals on the basis of membership in a protected group. Substance change is an event that results in the origin or cessation of individuals who may be members of groups with equal moral status. In this paper, two substance changes that affect the moral status of human embryos are identified. The first substance change begins with fertilization and ends with the formation of the blastocyst, a biological individual with moral status comparable to (...) that ascribed to human organs. The second substance change begins at implantation and ends late in embryological development with the formation of the human body, an organism with moral status as a human being. The bioethical implications of each substance change are explored. The Two Substance Change theory is contrasted with continuity theories, which recognize no substance change in embryological development and with fertilization-only substance change theories.

It is unclear whether someone’s responsibility for developing a disease or maintaining his or her health should affect what healthcare he or she receives. While this dispute continues, we suggest that, if responsibility is to play a role in healthcare, the concept must be rethought in order to reflect the sense in which many health-related behaviours occur repeatedly over time and are the product of more than one agent. Most philosophical accounts of responsibility are synchronic and individualistic; we indicate here (...) what paying more attention to the diachronic and dyadic aspects of responsibility might involve and what implications this could have for assessments of responsibility for health-related behaviour.
