In this paper, I discuss whether there are genuinely *diachronic* constraints of practical rationality, that is, pressures on combinations of practical attitudes over time, which are not reducible to mere synchronic rational pressures. Michael Bratman has recently argued that there is at least one such diachronic rational constraint that governs the stability of intentions over time. *Pace* Bratman, I argue that there are no genuinely diachronic constraints on intentions that meet the stringent desiderata set by him. But I show that (...) there are at least two synchronic rational constraints with distinctive and important, although only indirect, diachronic dimensions. Neither of them, however, supports the practical conservatism in the face of normative underdetermination that, according to Bratman, is part and parcel of the diachronic rationality of intention stability.

...there can be cases in which we reject pleasure because there is too much of it. Sometimes we decide that pleasure is bad, or not worth having, not because of an extrinsic factor like moral, aesthetic etc. constraints but rather because one is experiencing enough pleasure to the point that more would in itself be undesirable.

Abstract According to the Deprivation Approach, the evil of death is to be explained by the fact that death deprives us of the goods we would have enjoyed if we had lived longer. But the Deprivation Approach confronts a problem first discussed by Lucretius. Late birth seems to deprive us of the goods we would have enjoyed if we had been born earlier. Yet no one is troubled by late birth. So it’s hard to see why we should be troubled (...) by its temporal mirror image, early death. In a 1986 paper, Anthony Brueckner and John Martin Fischer appealed to a version of Derek Parfit’s “Bias toward the Future”; they claimed that early death deprives us of future goods that we care about, while late birth deprives us of past goods that we don’t care about. In this paper I show that the Brueckner–Fischer principle is open to several possible interpretations, but that it does not solve the Lucretius problem no matter how we understand it.

According to Jerome Wakefield’s harmful dysfunction analysis of medical disorder, the inability of some internal part or mechanism to perform its natural function is necessary, but not sufficient, for disorder. HDA also requires that the part dysfunction be harmful to the individual. I consider several problems for HDA’s harm criterion in this article. Other accounts on which harm is necessary for disorder will suffer from all or almost all of these problems. Comparative accounts of harm imply that one is harmed (...) when one is made worse off, that is, worse off than one otherwise would have been. Non-comparative accounts imply that one is harmed when one is put into some kind of condition or state that is, in some way, bad in itself. I argue that whether harm is construed comparatively or non-comparatively, HDA’s harm criterion is problematic. I tentatively conclude that an analysis of medical disorder should not make use of the concept of harm. (shrink)

Given that a person's death is bad for her,whenis it bad? I defendsubsequentism, the view that things that are bad in the relevant way are bad after they occur. Some have objected to this view on the grounds that it requires us to compare the amount of well-being the victim would have enjoyed, had she not died, with the amount she receives while dead; however, we cannot assign any level of well-being, not even zero, to a dead person. In the (...) population ethics literature, many philosophers have argued along similar lines that bringing someone into existence can neither harm nor benefit her. Working within the comparative framework (on which harms make us worse off), I respond by proposing a good sense in which we can say that dead people, and actual people at alternatives in which they do not exist, have a well-being level of zero.

The revolutionary potential of the CRISPR-Cas9 gene editing technique has created a resurgence in enthusiasm and concern in genetic research perhaps not seen since the mapping of the human genome at the turn of the century. Some such concerns and anxieties revolve around crossing lines between somatic and germline interventions as well as treatment and enhancement applications. Underpinning these concerns, there are familiar concepts of safety, unintended consequences and damage to genetic identity and the creation of designer children through pursuing (...) human enhancement and eugenics. In the policy realm, these morally laden distinctions and anxieties are emerging as the basis for making important and applied measures to respond to the fast-evolving scientific developments. This paper argues that the dominant normative framing for such responses is insufficient for this task. This paper illustrates this insufficiency as arising from a continued reliance on misleading genetic essentialist assumptions that generate groundless speculation and over-reactionary normative responses. This phenomenon is explicit with regard to prospective human genetic enhancements. While many normative theorists and state-of-the-art reports continue to gesture toward the influence of environmental and social influences on a person and their traits and capacities, this recognition does not extend to the substance of the arguments themselves which tend to revert to the debunked genetic determinist framework. Given the above, this paper argues that there is a pressing need for a more central role for sociological input into particular aspects of this “enhancement myth” in order to give added weight, detail and substance to these environmental influences and influence from social structures.

In some cases, a group of people can bring about a morally bad outcome despite each person’s individual act making no difference with respect to bringing that outcome about. Since each person’s act makes no difference, it seems the effects of the act cannot provide a reason not to perform it. This is problematic, because if each person acts in accordance with their reasons, each will presumably perform the act—and thus, the bad outcome will be brought about. Recently, Julia Nefsky (...) has argued that this problem is solved by rejecting the assumption that if an act makes no difference with respect to an outcome, then the act cannot do anything non-superfluous toward bringing that outcome about. Nefsky suggests that, even if an act makes no difference, the act may nevertheless help: it may make a non-superfluous causal contribution. If this is right, it means that the potential effects of an act may give us a reason to perform the act, even if the act wouldn’t make a difference. In this paper, I offer some reasons to be wary of Nefsky’s approach. I first argue that her account generates problematic results in a certain range of cases, and thus that we may have no reason to help in any case. I then argue that, even if we do sometimes have a reason to act when it seems we cannot make a difference, this reason cannot be the one that Nefsky identifies. (shrink)

Recently, Derek Parfit has offered a novel solution to the “Repugnant Conclusion” that compared with the existence of many people whose quality of life would be very high, there is some much larger number of people whose existence would be better but whose lives would be barely worth living. On this solution, qualitative differences between two populations will often entail that the populations are merely “imprecisely” comparable. According to Parfit, this fact allows us to avoid the Repugnant Conclusion without violating (...) the transitivity of better than. In this paper, I argue that Parfit’s view nevertheless implies two objectionable conclusions. The first is an alternative version of the Repugnant Conclusion that, Parfit suggests, may not be all that repugnant. The second is a revised version of the first that is nearly identical to the Repugnant Conclusion. I conclude that Parfit’s view offers no escape from repugnance. (shrink)

We analyse three moral dilemmas involving resource allocation in care for HIV-positive patients. Ole Norheim and Kjell Arne Johansson have argued that these cases reveal a tension between egalitarian concerns and concerns for better population health. We argue, by contrast, that these cases reveal a tension between, on the one hand, a concern for equal *chances*, and, on the other hand, both a concern for better health and an egalitarian concern for equal *outcomes*. We conclude that, in these cases, there (...) is much less tension than Norheim and Johansson claim between egalitarian concerns and concerns for better population health. (shrink)

The thesis of the paper is that persons are similar to a kind of group: multiple-expert epistemic unities (MEUs). MEUs are groups in which there are multiple experts on whom other members of the group model their opinion. An example would be a group of children playing Telephone. Any child nearer the source is an 'expert' for any child further away. I argue that, with certain important qualifications, it is both rational and necessary for persons to treat their future selves (...) as experts (i.e. to satisfy Bas Van Fraassen's Principle of Reflection). This makes a person a kind of MEU. (The paper "Epistemic Unities" gives more details about different kinds of epistemic unities.). (shrink)

The Millennium Development Goals were effective from 2000 to 2015. Statistics show that most of the goals were met, and particularly success in the goal of reducing extreme poverty gained wide recognition. Despite the strong ethical language related to poverty reduction, there has been little analysis of the ethical significance of the MDG achievements. Since statistical and ethical definitions and representations of poverty never completely overlap, conclusions concerning ethical progress are not directly available from the statistics. This article shows how (...) this ethical significance can be analysed and what kinds of controversies and uncertainties relate to the issue. As part of this analysis, utilitarian issues, population ethics, and the social aspect of poverty are discussed. Keywords: poverty, Millennium Development Goals, statistics, ethics, poverty line.

Ronald Dworkin claims in Life's Dominion that our tradition of religious toleration shields decisions to abort a pregnancy and to end one's life with the assistance of others because they pivot on judgements about the value of human life that are essentially spiritual. He further maintains that the state may regulate these decisions to ensure that they honour appropriately life's sacred or intrinsic value. This article disputes the first of Dworkin's claims. Tolerating other people's religious practices does not entail acquiescing (...) in conduct that is not religiously motivated but springs instead from normal moral judgements. This article also questions whether governments justifiably may protect entities or processes simply because some citizens deem them intrinsically valuable. If, despite these doubts, one concludes that the state may assume this protective role, I argue that it probably can enact tighter constraints on abortion and assisted suicide than Dworkin thinks permissible.

This paper criticizes the consequentialist theory recently put forward by Fred Feldman. I argue that this theory violates two crucial requirements. Another theory, proposed by Peter Vallentyne, is similarly flawed. Feldman's basic ideas could, however, be developed into a more plausible theory. I suggest one possible way of doing this.

This paper aims to offer a plausible and renewed defence of the axioms of the already well-known account of political philosophy ‘luck egalitarianism’. By finding certain support not only in the Kantian moral programme but also in widely accepted intuitions of our time, it is contended that luck egalitarianism possesses sufficient justification to become an ethical guide at the global level, revealing plausibly the existence of a compelling positive moral duty to terminate global poverty and denouncing its toleration as nothing (...) but a matter of injustice. The arguments provided to embrace such a proposal are built upon the widely accepted claim in moral philosophy that ‘all persons are equal in fundamental moral worth’. From this standpoint, I argue that the luck egalitarian doctrine can not only satisfy such a claim to its ultimate consequences, but it also reasonably overcome its most severe challenges that have diminished its merits in recent times when it aspires to become a tenable theory of justice.

The prospect of germ-line genetic engineering, the ability to engineer genetic changes that can be passed on to subsequent generations, raises a wide range of moral and public policy questions. One of the most provocative questions is, simply put: Are there moral reasons that can be articulated in general secular terms for accepting human nature as we find it? Or, at least in terms of general secular moral restraints, may we reshape human nature better to meet our own interests, as (...) we define them? This question in turn raises the further question of whether human nature as it now exists has a moral standing akin to sacredness that can be understood in nonreligious terms. This essay will take as a given that it is not possible to show in general secular moral terms that human nature has a sanctity or special moral standing that should guide secular health-care policy. In addition, as this essay shows, it is not possible through appeals to considerations of authorizing consent or beneficence toward others to remedy this failure to establish a sanctity or special moral standing for human nature. Absent a religious or culturally normative understanding of human nature and given the availability of germline genetic engineering, there is a plurality of possibilities for refashioning our nature. The unavailability of substantive secular moral constraints on germ-line genetic engineering discloses a secularly licit plurality of possibilities for human nature. The likelihood that we will be able to refashion our human nature reveals how few general secular moral constraints there are to guide us. Paradoxically, the more we are able to reengineer our human nature, the less guidance is available. The plurality of possible conceptions of human well-being that can be pursued through germ-line genetic engineering challenges our self-understanding as humans. Given human freedom, and in the absence of taken-for-granted religious or cultural moral constraints, the likelihood of germ-line genetic engineering opens the possibility of human nature in the plural.

Counter-intuitive consequences of both causal decision theory and evidential decision theory are dramatized. Each of those theories is thereby put under some pressure to supply an error theory to explain away intuitions that seem to favour the other. Because trouble is stirred up for both sides, complacency about Newcomb’s problem is discouraged.

This paper seeks to identify a mid-level unifying ethical principle that may help clarify and articulate the ethical responsibilities of business firms in the field of marketing ethics. The paper examines critically the main principles which have been proposed to date in the literature, namely consumer sovereignty, preserving the conditions of an acceptable exchange, paternalism, and the perfect competition ideal, and concludes that all of them are vulnerable to damaging criticisms. The paper articulates and defends the mutuality principle as the (...) most plausible candidate for the role of master principle in the relations between a firm and its customers. This principle requires that sellers look for reciprocity in their relations with their customers, seeking to provide to their customers something that helps them improve in some way their well-being and is commensurate with what they receive from them.

Consequentialism has trouble explaining why hypocrisy is a term of moral condem-nation, largely because hypocrites often try to deceive others about their own selfishness through the useof words or deeds which themselves have good consequences. We argue that consequentialist attempts to deal with the problem by separating the evaluation of agent and action, or by the directevaluation of dispositions, or by focusing on long-term consequences such as reliability and erosion of trust, all prove inadequate to the challenge. We go on (...) to argue, however, that a version of consequentialism which values the fulfilment of desires, rather than mental states, is able to explain why hypocrisy is generally wrong, and indeed can do so better than its Kantian rivals.

Mark Johnston and Eric Olson have both pressed what Johnston has dubbed the personite problem. Personites, if they exist, are person-like entities whose lives extend over a continuous proper part of a person’s life. They are so person-like that they seem to have moral status if persons do. But this threatens to wreak havoc with ordinary moral thinking. For example, simple decisions to suffer some short-term hardship for long-term benefits become problematic. And ordinary punishment is always also punishment of the (...) innocent, since it punishes personites that didn’t exist when the crime was committed. An initially attractive way around the personite problem may be to simply deny that personites exist. But as I discuss in this talk, relating to contemporary discussions in metaontology, this response for principled reasons doesn’t work. The problems I discuss illustrate the significance of metaontological considerations for issues in ethics and metaethics, and generalize widely beyond the personite problem. (shrink)

This paper examines the ethical aspects of organ transplant surgery in which a donor heart is transplanted from a first recipient, following determination of death by neurologic criteria, to a second recipient. Retransplantation in this sense differs from that in which one recipient undergoes repeat heart transplantation of a newly donated organ, and is thus referred to here as “reuse cardiac organ transplantation.” Medical, legal, and ethical analysis, with a main focus on ethical analysis. From the medical perspective, it is (...) critical to ensure the quality and safety of reused organs, but we lack sufficient empirical data pertaining to medical risk. From the legal perspective, a comparative examination of laws in the United States and Japan affirms no illegality, but legal scholars disagree on the appropriate analysis of the issues, including whether or not property rights apply to transplanted organs. Ethical arguments supporting the reuse of organs include the analogous nature of donation to gifts, the value of donations as inheritance property, and the public property theory as it pertains to organs. Meanwhile, ethical arguments such as those that address organ recycling and identity issues challenge organ reuse. We conclude that organ reuse is not only ethically permissible, but even ethically desirable. Furthermore, we suggest changes to be implemented in the informed consent process prior to organ transplantation. The organ transplant community worldwide should engage in wider and deeper discussions, in hopes that such efforts will lead to the timely preparation of guidelines to implement reuse cardiac organ transplantation as well as reuse transplantation of other organs such as kidney and liver.

Given reductionism about people, personal persistence must fundamentally consist in some kind of impersonal continuity relation. Typically, these continuity relations can hold from one to many. And, if they can, the analysis of personal persistence must include a non-branching clause to avoid non-transitive identities or multiple occupancy. It is far from obvious, however, what form this clause should take. This paper argues that previous accounts are inadequate and develops a new proposal.

A compelling requirement on normative theories is that they should be satisfiable, that is, in every possible choice situation with a finite number of alternatives, there should be at least one performable act such that, if one were to perform that act, one would comply with the theory. In this paper, I argue that, given some standard assumptions about free will and counterfactuals, Objective Act Consequentialism violates this requirement.

Recent experimental studies indicate that epistemically irrelevant factors can skew our intuitions, and that some degree of scepticism about appealing to intuition in philosophy is warranted. In response, some have claimed that philosophers are experts in such a way as to vindicate their reliance on intuitions—this has become known as the ‘expertise defence’. This paper explores the viability of the expertise defence, and suggests that it can be partially vindicated. Arguing that extant discussion is problematically imprecise, we will finesse the (...) notion of ‘philosophical expertise’ in order to better reflect the complex reality of the different practices involved in philosophical inquiry. On this basis, we offer a new version of the expertise defence that allows for distinct types of philosophical expertise. The upshot of our approach is that wholesale vindications or rejections of the expertise defence are shown to be unwarranted; we must instead turn to local, piecemeal investigations of philosophical expertise. Lastly, in the spirit of taking our own advice, we exemplify how recent developments from experimental philosophy lend themselves to this approach, and can empirically support one instance of a successful expertise defence.

Current orthodoxy in research ethics assumes that subjects of clinical trials reserve rights to withdraw at any time and without giving any reason. This view sees the right to withdraw as a simple extension of the right to refuse to participate all together. In this paper, however, I suggest that subjects should assume some responsibilities for the internal validity of the trial at consent and that these responsibilities should be captured by contract. This would allow the researcher to impose a (...) penalty on the subject if he were to withdraw without good reason and on a whim. This proposal still leaves open the possibility of withdrawing without penalty when it is in the subject's best interests to do so. Giving researchers recourse to legal remedy may now be necessary to protect the science, as existing methods used to increase retention are inadequate for one reason or another. (shrink)

This paper explores the implications that the construction and use of avatars in games such as Second Life and World of Warcraft have for our understanding of personal identity. It asks whether the avatar can meaningfully be experienced as a separate person, existing in parallel to the flesh and blood player. A rehearsal of Cartesian and Lockean accounts of personal identity constructs an understanding of the self that is challenged by the experience of online play. It will be argued that (...) playful engagement in virtual worlds invites the participant to reflect upon the human being as embodied and social; qualities of which are marginalised by Descartes and Locke. The strangeness of this experience of virtual worlds confronts the player with a challenge to construct a coherent narrative of online life, of which treating the avatar as a separate person is a coherent option. This opens up the virtual world as an important space within which personal identity is explored, but one with complex implicati... (shrink)

Background: Recent literature on addiction and judgments about the characteristics of agents has focused on the implications of adopting a ‘brain disease’ versus ‘moral weakness’ model of addiction. Typically, such judgments have to do with what capacities an agent has (e.g., the ability to abstain from substance use). Much less work, however, has been conducted on the relationship between addiction and judgments about an agent’s identity, including whether or to what extent an individual is seen as the same person after (...) becoming addicted. Methods: We conducted a series of vignette-based experiments (total N = 3,620) to assess lay attitudes concerning addiction and identity persistence, systematically manipulating key characteristics of agents and their drug of addiction. Conclusions: In Study 1, we found that US participants judged an agent who became addicted to drugs as being closer to ‘a completely different person’ than ‘completely the same person’ as the agent who existed prior to the addiction. In Studies 2-6, we investigated the intuitive basis for this result, finding that lay judgments of altered identity as a consequence of drug use and addiction are driven primarily by perceived negative changes in the moral character of drug users, who are seen as having deviated from their good true selves.

The Procreation Asymmetry holds that we have strong moral reasons not to create miserable people for their own sakes, but no moral reasons to create happy people for their own sakes. To defend this conjunction against an argument that it leads to inconsistency, I show how recognizing ‘creation’ as a temporally extended process allows us to revise the conjuncts in a way that preserves their intuitive force. This defense of the Procreation Asymmetry is preferable to others because it does not (...) require us to take on controversial metaphysical or metaethical commitments – in other words, it has the theoretical virtue of portability.

I can be aware of myself, and thereby come to know things about myself, in a variety of different ways. But is there some special way in which I—and only I—can learn about myself? Can I become aware of myself by introspecting? Do I somehow show up in my own conscious experiences? David Hume and most contemporary philosophers say no. They deny that the self shows up in experience. However, in this paper I appeal to research on schizophrenia—on thought insertion, (...) in particular—to argue that Hume and his follows are wrong: The self does, in fact, show up in experience.

Suppose that you're lying in bed. You just woke up. But you're alert. Your mind is clear and you have no distractions. As you lie there, you think to yourself, ‘2 + 2 = 4.’ The thought just pops into your head. But, wanting to be sure of your mathematical insight, you once again think ‘2 + 2 = 4’, this time really meditating on your thought. Now suppose that you're sitting in an empty movie theatre. The lighting is normal (...) and the screen in front of you is blank. Then at some point an image of a peach is flashed on the screen. The image isn't up there for long. In fact, it's only on the screen for what seems like an instant—just long enough for you to see it. These two scenarios are a bit mundane. But, as I will show, reflection on them can yield significant results concerning the nature of persons and their persistence through time. First I will show that thought and perception have temporal constraints whereby your thinking or perceiving in the above scenarios implies that you exist through a temporally.. (shrink)

Sometimes in philosophy one view engenders another. If you hold the first, chances are you hold the second. But it’s not always because the first entails the second. Sometimes the tie is less clear, less clean. One such tie is between substance dualism and anti-criterialism. Substance dualism is the view that people are, at least in part, immaterial mental substances. Anti-criterialism is the view that there is no criterion of personal identity through time. Most philosophers who hold the first view (...) also hold the second. In fact, many philosophers just assume that substance dualists ought to, or perhaps even have to, accept anti-criterialism. But I aim to show that this assumption is baseless. Substance dualism doesn’t entail, suggest, support, or in any way motivate anti-criterialism, and anti-criterialism confers no benefit on dualism. Substance dualists have no special reason—and, indeed, no good reason at all—to accept anti-criterialism. Or so I shall argue. My aim isn’t to defend substance dualism, nor is it to attack anti-criterialism. My aim is to show that, contrary to a long-standing trend, dualists needn’t be anti-criterialists. Nor, as it will turn out, should they be. (shrink)

It is now broadly accepted that disability is a concept infused with both descriptive and evaluative meaning, such that invoking the concept of disability necessarily involves making judgements of moral value as well as describing certain facts about individuals. This paper aims to map the complex terrain that shapes our current understandings of disability by outlining five distinct ‘discourses of disability’. It is shown how the similarities and differences between the discourses hinge on different ways of making sense of the (...) descriptive and evaluative dimensions of the concept, and the relationships between these dimensions. The paper concludes by considering the specific implications that these different ways of elucidating the concept of disability might have for the provision of clinical ethics support, both in terms of shaping ethical decision-making relating to people with disabilities and in terms of framing the process of providing clinical ethics support itself.

In this paper I make a contribution to three distinct, but deeply interwoven subjects. Firstly, I argue that, at the level of ideal theory, the distribution of educational goods should follow a sufficientarian pattern and that the evaluative space of children’s advantage should be inspired by the capability approach. Secondly, the paper is delving into the more policy-oriented debates on the desirability of school choice. I argue that, given the non-ideal circumstances in which decision makers have to act, giving parents (...) the opportunity to choose the school for their children is a sine qua non condition for even approaching the ideals of sufficientarian justice. Lastly, I move the discussion on more empirical grounds, advancing a criticism of the Romanian educational legislation. I argue that the sufficiency-constrained school choice system that I envision could solve some of the problems that the Romanian educational system faces today. (shrink)

According to the Phenomenal Unity Thesis (“PUT”) – most prominently defended by Tim Bayne and David Chalmers – necessarily, any set of phenomenal states of a subject at a time is phenomenally unified. The standard formulation of this thesis is unacceptably vague because it does not specify what it is to be a subject. In this paper, I first consider possible meanings for ‘subject’ as used in PUT and argue that every plausible candidate definition renders the thesis trivially true. I (...) consider and reject Tim Bayne’s proposal that ‘subject’ means ‘human being’. Then I argue, contra Bayne and Chalmers, that PUT is not incompatible with any major theory of consciousness, and contra Michael Tye, that split-brain patients do not provide evidence against PUT. I close by considering some nontrivial alternatives to PUT. (shrink)

In this paper, I provide an argument for pannormism, the view according to which there are normative properties all the way down. In particular, I argue for what I call the trickling down principle, which says that if there is a metaphysically basic normative property, then, if whatever instantiates it has a ground, that ground instantiates it as well.

I develop and argue for a kind of externalism about certain kinds of non-doxastic attitudes that I call policy externalism. Policy externalism about a given type of attitude is the view that all the reasonable policies for having attitudes of that type will not involve the agent's beliefs that some relevant conditions obtain. My defense primarily involves attitudes like hatred, regret, and admiration, and has two parts: a direct deductive argument and an indirect linguistic argument, an inference to the best (...) explanation of some strange ways we use certain conditionals. The main thought throughout is that attitudes we reason with, like belief, are very different from attitudes we don't reason with, in a way that constrains the former but not the latter. Finally, I investigate some consequences of policy externalism, including that it secures the possibility of genuine conditional apologies. (shrink)

Climate change and many environmental problems are caused by the accumulated effects of repeated actions by multiple individuals. Instead of relying on collective responsibility, I argue for a non-atomistic individual responsibility towards such environmental problems, encompassing omissions, ways of life, and consequences mediated by other agents. I suggest that the degree of causal responsibility of the agent must be balanced with the degree of capacity-responsibility determined by the availability of doable alternatives. Then, the more an agent has powers as a (...) group member, the more she is responsible to design the social structure and the infrastructures of the group towards sustainability. Finally, one can hold another agent responsible only if the accused is not in a vulnerable position and if she is capable to take reparative and adaptive actions. (shrink)

In his stimulating recent book Reasons without Persons, Brian Hedden develops a novel theory of rationality that he calls Time-Slice Rationality. One of the main theses of TSR is that all rational requirements are synchronic. We argue here first that this thesis is not well-motivated. We also demonstrate that Hedden is in fact committed to an even stronger claim about the rationality of an agent at a time. Finally, we provide some arguments against the conception of rationality that results from (...) this stronger claim. (shrink)

The standard approach to the so-called paradoxes of identity has been to argue that these paradoxes do not essentially concern the notion of identity but rather betray misconceptions on our part regarding other metaphysical notions, like that of an object or a property. This paper proposes a different approach by pointing to an ambiguity in the identity predicate and arguing that the concept of identity that figures in many ordinary identity claims, including those that appear in the paradoxes, is not (...) the traditional philosophical concept but one that can be defined in terms of relevant similarity. This approach to the paradoxes will be argued to be superior to the standard one. (shrink)

One prevalent type of slippery slope argument has the following form: (1) by doing some initial act now, we will bring it about that we subsequently do some more extreme version of this act, and (2) we should not bring it about that we do this further act, therefore (3) we should not do the initial act. Such arguments are frequently regarded as mistaken, often on the grounds that they rely on speculative or insufficiently strong empirical premises. In this article (...) I point out another location at which these arguments may go wrong: I argue that, in their standard form, the truth of their empirical premises constitutes evidence for the falsity of their normative premises. If we will, as predicted, do the further act in the future, this gives us at least a prima facie reason to believe that the performance of this further act would be good, and thus something we should try to bring about. I end by briefly assessing the dialectic implications of my argument. I delineate a subset of slippery slope arguments against which my objection may be decisive, consider how the proponents of such arguments may evade my objection by adding further premises, and examine the likely plausibility of these additional premises.

Several authors have speculated that (1) the pharmaceutical, genetic or other technological enhancement of human mental capacities could result in the creation of beings with greater moral status than persons, and (2) the creation of such beings would harm ordinary, unenhanced humans, perhaps by reducing their immunity to permissible harm. These claims have been taken to ground moral objections to the unrestrained pursuit of human enhancement. In recent work, Allen Buchanan responds to these objections by questioning both (1) and (2). (...) I argue that Buchanan’s response fails. However, I then outline an alternative response. This response starts from the thought that, though moral status-increasing human enhancements might render ordinary, unenhanced humans less immune to permissible harm, they need not worsen the overall distribution of this immunity across beings. In the course of the argument I explore the relation between mental capacity and moral status and between moral status and immunity to permissible harm. (shrink)
