This thesis is about the moral reasons we have to do less than best. It consists of six chapters. Part I of the thesis proposes, extends, and defends reasons to do less than best. In Chapter One (“The Conditional Obligation”) I outline and reject two recent arguments from Joe Horton and Theron Pummer for the claim that we have a conditional obligation to bring about the most good. In Chapter Two (“Agglomeration and Agent-Relative Costs”) I argue that agent-relative costs can (...) justify permissions to less than best in a far greater range of decisions contexts than we currently believe. In Chapter Three (“Risk and Aggregation”) I discuss how anti-aggregative moral theories deal with risk, whilst proposing an argument in favour of ex-post moral theories. -/- In Part II of the thesis, I discuss longtermism, presenting a series of reasons to believe we have both significant permissions and obligations to prioritise those in the short-term. In Chapter Four (“Listening to Future People”) I criticise a recent argument presented by Andreas Mogensen for the claim we cannot have obligations grounded in the wellbeing of future people. I then show that, even permitting the existence of obligations to future people, we still have significant reasons to resist longtermism on the grounds of partiality. In Chapter Five (“The Complaints of Future People”) I argue that scepticism about aggregation is inconsistent with an obligation, or indeed even a permission, to help far future people. In Chapter Six (“Leaving the Present Behind”) I explore the moral significance of “dooming”, whilst arguing that we have a pro tanto reason of fairness to prioritise aiding those currently in existence.

Procreative obligations are often discussed by evaluating only the consequences of reproductive actions or omissions; less attention is paid to the moral role of intentions and attitudes. In this paper, I assess whether intentions and attitudes can contribute to defining our moral obligations with regard to assisted reproductive technologies already available, such as preimplantation genetic diagnosis (PGD), and those that may be available in future, such as reproductive genome editing and ectogenesis, in a way compatible with person‐affecting constraints. I propose (...) the parent–child relationship argument, which is based on the moral distinction between creating and parenting a child. Hence, I first argue that intentions and attitudes can play a role in defining our moral obligations in reproductive decisions involving PGD. Second, I maintain that if we accept this and recognize reproductive genome editing and ectogenesis as person‐affecting procedures, we should be committed to arguing that prospective parents may have moral reasons to prefer reproduction via such techniques than via sexual intercourse. In both cases, I observe an extension of our procreative responsibility beyond what is proposed by the consequentialist person‐affecting morality. (shrink)

The past few years has seen a resurgence in the public interest in space flight and travel. Spurred mainly by the likes of technology billionaires like Elon Musk and Jeff Bezos, the topic poses both unique scientific as well as ethical challenges. This paper looks at the concept of generation ships, conceptual behemoth ships whose goal is to bring a group of human settlers to distant exoplanets. These ships are designed to host multiple generations of people who will be born, (...) live, and die on these ships long before it reaches its destination. This paper takes reproductive ethics as its lens to look at how genetic enhancement interventions can and should be used not only to ensure that future generations of offspring on the ships, and eventual exoplanet colonies, live a minimally good life but that their births are contingent on them living genuinely good and fulfilling lives. The paper makes the further claim that if such a thesis holds, it also does so for human enhancement on Earth. (shrink)

Janet Malek has recently argued that the religious worldview of the clinical ethics consultant should play no normative role in clinical ethics consultation. What are the theological implications of a normatively secular clinical ethics? I argue that Malek’s proposal constitutes an irreligious clinical ethics, which commits multiple metaphysical harms. First, I summarize Malek’s key claims for a secular clinical ethics. Second, I explicate both John Milbank’s notion of ontological violence and Timothy Murphy’s irreligious bioethics to show how they apply to (...) Malek’s secular clinical ethics, resulting in an irreligious clinical ethics. Third, I then show how an irreligious clinical ethics commits metaphysical harms to patients, clinical ethics consultants, and the institution of clinical ethics consultation. I conclude that Malek’s proposal for an irreligious clinical ethics must be rejected to maintain the metaphysical integrity of clinical ethics consultants, patients, and the institution of clinical ethics consultation.

If bioethical questions cannot be resolved in a widely acceptable manner by rational argument, and if they can be regulated only on the basis of political decision-making, then bioethics belongs to the political sphere. The particular kind of politics practiced in any given society matters greatly: it will determine the kind of bioethical regulation, legislation, and public policy generated there. I propose approaching bioethical questions politically in terms of decisions that cannot be “correct” but that can be “procedurally legitimate.” Two (...) procedures in particular can deliver legitimate bioethical decisions, once combined: expert bioethics committees and deliberative democracy. Bioethics so understood can exceed bioethics as a moral project or as a set of administrative principles to regulate medical practice; it can now aspire to a democratic project that involves ordinary citizens as far as reasonably possible. I advance this argument in four steps: (1) using the example of human germline gene editing, (2) I propose a general understanding of proceduralism, and (3) then combine two types and (4) conclude with a defense of majoritarian proceduralism. I develop this argument in terms of one example: germline gene editing. (shrink)

Many people view disabilities as misfortunes, call this the standard view. In this paper, I examine one criticism that has been launched against the Standard View. Rather than determine in advance whether having a disability is good or bad for a person, some critics argue that the Standard View is reflective of and brings about inappropriate emotional responses toward people with disabilities and their circumstances. For instance, philosophers have recently argued that in holding the standard view, we become prone to (...) a destructive kind of unwarranted pity or that the view leads us to hold certain untenable or inappropriate hopes for our children and for our society. I think this sort of challenge to the Standard View has a lot of appeal, but I worry that if it is not properly articulated, the approach is vulnerable to what has been known as “The Wrong Kind of Reason” problem. The paper highlights and addresses this worry. (shrink)

When it originated in the late 19th century, psychometrics was a field with both a scientific and a social mission: psychometrics provided new methods for research into individual differences, and at the same time, these psychometric instruments were considered a means to create a new social order. In contrast, contemporary psychometrics - due to its highly technical nature and its limited involvement in substantive psychological research - has created the impression of being a value-free discipline. In this article, we develop (...) a contrasting characterization of contemporary psychometrics as a value-laden discipline. We expose four such values: that individual differences are quantitative (rather than qualitative), that measurement should be objective in a specific sense, that test items should be fair, and that utility of a model is more important than its truth. Our goal is not to criticize psychometrics for employing these values, but rather to bring them into the open and to show that these values are not inevitable and are in need of systematic evaluation.

Ever since the publication of Derek Parfit’s Reasons and Persons, bioethicists have tended to distinguish between two different ways in which reproductive technologies may have implications for the...

Assisted reproductive technologies have greatly increased our control over reproductive choices, leading some bioethicists to argue that we face unprecedented moral obligations towards progeny. Several models attempting to balance the principle of procreative autonomy with these obligations have been proposed. The least demanding is the minimal threshold model (MTM), according to which every reproductive choice is permissible, except creating children whose lives will not be worth living. Hence, as long as the future child is likely to have a life worth (...) living, prospective parents may be allowed to use preimplantation genetic diagnosis (PGD) to select embryos with genetic diseases or disabilities. Assuming a consequentialist person‐affecting view of morality, this paper investigates whether the MTM is an appropriate tool to guide procreative decisions given the continuous development of reproductive genetic technologies. In particular, I consider germline genome editing (GGE) and I argue that its application in human reproduction, unlike PGD, should be conceived as person‐affecting towards future progeny. I claim that even if we assume the plausibility of the MTM within PGD, we are committed to accepting that a greater moral obligation towards progeny should guide procreative decisions if GGE were available. In this case, the MTM should no longer be considered an appropriate instrument to guide procreative choices. Finally, I investigate when we face this greater moral obligation, concluding that it applies only when prospective parents have already engaged in the in vitro fertilization process. (shrink)

Augustine’s legacy, particularly his view of marriage as being primarily procreative and the sin of mutually desired non-procreative sex, has had a lasting impact on sexual theology and ethics in the Catholic Church. Yet indulging in the Augustinian legacy without reflection and regarding children as the end goal of marriage has led to the unchallenged assumption that children are needed in every marriage. I will examine the problematic concept of matrimony as a necessary producer of children through a variety of (...) ethical lenses – the environmental, the feminist, and the bioethical – and provide an alternative to the procreative norm of sexual expression. By focusing on the unitive aspect of marital love instead of the procreative, partners are liberated to realize their union as fully mature, regardless of biological generation thus addressing ethical concerns and providing a theological alternative to the procreative marriage.

No filme Gattaca, imagina-se um futuro já nada distante em que os casais poderão consultar um especialista em fertilização artificial e escolher as características de seu futuro filho. Eles podem selecionar embriões fertilizados em laboratório, podendo também alterar seus traços genéticos, eliminando genes capazes de expressar doenças ou mesmo características físicas indesejáveis. Técnicas recentes, como a edição genética por Prime Editing ou por meio da CRISPR-Cas9, logo permitirão terapias gênicas em embriões fertilizados in vitro antes de sua implantação uterina. Neste (...) artigo, pretendemos avaliar essas possibilidades, revisando criticamente alguns argumentos conhecidos contra o uso indiscriminado de tais técnicas. Ao final, em defesa de que objeções de princípio a práticas eugênicas devem estar assentadas na proteção e promoção dos direitos humanos, pretendemos avaliar quais limites poderiam publicamente justificar a permissão ou proibição do uso privado de tais técnicas.

Most people have a clear sense of what they mean by disability, and have little trouble identifying conditions they consider disabling. Yet providing a clear and consistent definition of disability is far from straightforward. Standardly, disability is understood as the restriction in our abilities to perform tasks, as a result of an impairment of normal physical or cognitive human functioning. However, which inabilities matter? We are all restricted by our bodies, and are all incapable of performing some tasks, but most (...) of these inabilities are not considered disabilities. If, then, we are to avoid the category of disability becoming overly broad—and thus politically and practically useless—we need some way of picking out the specific inabilities that are disabling. I argue that our answer should be informed by an account of the opportunities individuals are entitled to be able to perform as a matter of justice. Thus, to be disabled is to have these opportunities restricted, and not to deviate from the species norm or lack any ability that might improve our well-being. (shrink)

This is a critical response to "Defending Eugenics", published in MBR in 2018.

For most of human history children have been a byproduct of sex rather than a conscious choice by parents to create people with traits that they care about. As our understanding of genetics advances along with our ability to control reproduction and manipulate genes, prospective parents have stronger moral reasons to consider how their choices are likely to affect their children, and how their children are likely to affect other people. With the advent of cheap and effective contraception, and the (...) emergence of new technologies for in vitro fertilization, embryo selection, and genetic engineering, it is becoming increasingly difficult to justify rolling the genetic dice by having children without thinking about the traits they will have. It is time to face up to the awesome responsibilities that accompany our reproductive choices. (shrink)

Preimplantation genetic diagnosis allows the detection of genetic abnormalities in embryos produced through in vitro fertilization. Current funding models in Australia provide governmental subsidies for couples undergoing IVF, but do not extend to PGD. There are strong reasons for publicly funding PGD that follow from the moral principles of autonomy, beneficence and justice for both parents and children. We examine the objections to our proposal, specifically concerns regarding designer babies and the harm of disabled individuals, and show why these are (...) substantially outweighed by arguments for subsidizing PGD. We argue that an acceptance of PGD is aligned with present attitudes towards procreative decision making and IVF use, and that it should therefore receive government funding. (shrink)

Eugenics is often referred to in debates on the ethics of reproductive technologies and practices, in relation to the creation of moral boundaries between acceptable and unacceptable technologies, and acceptable and unacceptable uses of these technologies. Historians have argued that twentieth century eugenics cannot be reduced to a uniform set of practices, and that no simple lessons can be drawn from this complex history. Some authors stress the similarities between past eugenics and present reproductive technologies and practices (what I define (...) throughout the paper as ‘the continuity view’) in order to condemn the latter. Others focus on the differences between past and present practices (what I define throughout the paper as ‘the discontinuity view’) in order to defend contemporary reproductive technologies. In this paper, I explore the meanings of the word ‘eugenics’ and the relationship between its past and present uses in terms of contemporary debates on reproductive technologies and practices. I argue that moral disagreement about present technologies originate in divergent views of condemnable and justifiable features of the past. (shrink)

Em primeiro lugar, são apresentados os dois principais argumentos contra essa tentativa, as ideias de que isso prejudicaria o filho e de que os pais não estariam buscando o melhor para ele. Em seguida são apresentados três contra-argumentos a favor da escolha dos pais, que se baseiam nas considerações de que a surdez não é uma deficiência, de que essa escolha (...) aumentaria o vínculo entre pais e filhos e de que ela serviria como uma ação afirmativa a favor dos portadores de deficiências.

Proponents of moral enhancement believe that we should pursue and apply biotechnological means to morally enhance human beings, as failing to do so is likely to lead to humanity's demise. Unsurprisingly, these proposals have generated a substantial amount of debate about the moral permissibility of using such interventions. Here I put aside concerns about the permissibility of moral enhancement and focus on the conceptual and evidentiary grounds for the moral enhancement project. I argue that such grounds are quite precarious.

Annotated bibliography on eugenics and philosophy.

The view that it is better for life to be created free of disability is pervasive in both common sense and philosophy. We cast doubt on this view by focusing on an influential line of thinking that manifests it. That thinking begins with a widely-discussed principle, Procreative Beneficence, and draws conclusions about parental choice and disability. After reconstructing two versions of this argument, we critique the first by exploring the relationship between different understandings of well-being and disability, and the second (...) by more briefly focusing on the idea of a significant reason. By placing these results against the broader historical and ongoing contexts in which the lives of those with disabilities have been deemed of inferior quality, we conclude with a call for greater humility about disability and well-being in thought and practice.

This paper presents an overview of the key ethical questions of performing gene editing research on military service members. The recent technological advance in gene editing capabilities provided by CRISPR/Cas9 and their path towards first-in-human trials has reinvigorated the debate on human enhancement for non-medical purposes. Human performance optimization has long been a priority of military research in order to close the gap between the advancement of warfare and the limitations of human actors. In spite of this focus on temporary (...) performance improvement, biomedical enhancement is an extension of these endeavours and the ethical issues of such research should be considered. In this paper, we explore possible applications of CRISPR to military human gene editing research and how it could be specifically applied towards protection of service members against biological or chemical weapons. We analyse three normative areas including risk–benefit analysis, informed consent, and inequality of access as it relates to CRISPR applications for military research to help inform and provide considerations for military institutional review boards and policymakers.

In The Minority Body, Elizabeth Barnes rejects prevailing social constructionist accounts of disability for two reasons. First, because they understand disability in terms of oppressive social responses to bodily impairment, they cannot make sense of disability pride. Second, they maintain a problematic distinction between impairment and disability. In response to these challenges, this paper defends a version of the social model of disability, which we call the Social Exclusion Model. On our account, to be disabled is to be in a (...) bodily or psychological state that is represented as an impairment in the prevailing ideology of one’s society, and to be excluded from valuable activities on the basis of this representation. While this model refers to a distinction between disability and impairment, it makes no presuppositions about which bodies function ‘normally’ and which do not. It is the ideology of impairment rather than impairment itself that does any work to determine whether a person is disabled. We argue that this model answers some of the important objections that Barnes raises against prevailing social constructionist accounts of disability, and that it’s focus on the oppressive social positioning of disabled people gives it explanatory power that Barnes’s own account lacks.

The disability critique of negative genetic selection is frequently accused of threatening reproductive liberty. This paper describes the disability critique and defends it against that objection. It also contends that the critique can work to deflate belief in genetic determinism. Recognizing the influence of genetic determinism helps advocate for existing persons in the disability community and protects reproductive liberty. The disability critique can point to genetic determinism but does not suggest a ban or obstacles to the choice of negative genetic (...) selection; therefore, it is not antithetical to reproductive liberty, as has been charged.

If it is within our power to provide a significantly better world for future generations at a comparatively small cost to ourselves, we have a strong moral reason to do so. One way of providing a significantly better world may involve replacing our species with something better. It is plausible that in the not‐too‐distant future, we will be able to create artificially intelligent creatures with whatever physical and psychological traits we choose. Granted this assumption, it is argued that we should (...) engineer our extinction so that our planet's resources can be devoted to making artificial creatures with better lives. (shrink)

Prenatal diagnosis challenges the issue of parental autonomy. Two ethical aspects of the parental decision making process with reference to PND have been taken into consideration: the duty to know and the right not to know. Whilst the first approach has been widely discussed in literature, the latter seems to be overlooked. In order to find good moral reasons supporting the right not to know, firstly the duty to know approach was critically analysed. Subsequently, the emphasis was put on the (...) unconditional parental love and the issue of child’s best interests as the features supporting parental right not to know. The clarification of what is good parenthood was presented as the best normative approach supporting the parental right not to know in case of PND. Apart from parental autonomy, raising the question of the right not to know is important in the debate about the place and role of people with disabilities in society. (shrink)

It is commonly thought that when a patient is unable to make a treatment decision for herself, patient autonomy should be respected by consulting the views of a patient surrogate, normally either the next-of-kin or a person previously designated by the patient. On one view, the task of this surrogate is to make the treatment decision that the patient would have made if competent. But this so-called ‘substituted judgment standard’ (SJS) has come in for has come in for a good (...) deal of criticism recently. For instance, some question whether surrogates are able to reliably predict what the patient would have chosen. Others wonder how respecting a patient's counter-factual, rather than actual, choices is supposed to respect her autonomy. Such concerns have lead some to reject the SJS and argue for alternative characterisations of the role of surrogate decision-makers. (shrink)

The aim of this paper is to criticise the well-discussed Principle of Procreative Beneficence (PB) lately refined by Julian Savulescu and Guy Kahane. First, it is argued that advocates of PB leave us with an implausible justification for the moral partiality towards the child (or children) reproducers decide to bring into existence as compared with all other individuals. This is implausible because the reasons given in favour of the partiality of PB, which are based on practical reason and common-sense morality, (...) can just as well be used to guide reproducers to make choices that do not support partiality towards one’s possible children. This seems to be true as least in some situations. Secondly, it is argued that Jakob Elster’s recent critique of PB is problematic, and specifically that a counterexample designed by Elster to criticise PB because of its partiality towards one’s own children misses the target. Finally, a genuine counterexample to PB is developed in order to show that the partiality of PB means it gives the wrong answer in a specific case. (shrink)

While pre-implantation genetic diagnosis is available and legal in Malaysia, there is an ongoing controversy debate about its use. There are few studies available on individuals’ attitudes toward PGD, particularly among those who have a genetic disease, or whose children have a genetic disease. To the best of our knowledge, this is, in fact, the first study of its kind in Malaysia. We conducted in-depth interviews, using semi-structured questionnaires, with seven selected potential PGD users regarding their knowledge, attitudes and decisions (...) relating to the use PGD. The criteria for selecting potential PGD users were that they or their children had a genetic disease, and they desired to have another child who would be free of genetic disease. All participants had heard of PGD and five of them were considering its use. The participants’ attitudes toward PGD were based on several different considerations that were influenced by various factors. These included: the benefit-risk balance of PGD, personal experiences of having a genetic disease, religious beliefs, personal values and cost. The study’s findings suggest that the selected Malaysian participants, as potential PGD users, were supportive but cautious regarding the use of PGD for medical purposes, particularly in relation to others whose experiences were similar. More broadly, the paper highlights the link between the participants’ personal experiences and their beliefs regarding the appropriateness, for others, of individual decision-making on PGD, which has not been revealed by previous studies.

Recent work in the psychology of happiness has led some to conclude that we are unreliable assessors of our lives and that skepticism about whether we are happy is a genuine possibility worth taking very seriously. I argue that such claims, if true, have worrisome implications for procreation. In particular, they show that skepticism about whether many if not most people are well positioned to create persons is a genuine possibility worth taking very seriously. This skeptical worry should not be (...) confused with a related but much stronger version of the argument, which says that all human lives are very bad and not worth starting. I criticize the latter stance, but take seriously the former stance and hope it can be answered in future work. (shrink)

In this paper I present an argument in favour of a parental duty to use preimplantation genetic diagnosis (PGD). I argue that if embryos created in vitro were able to decide for themselves in a rational manner, they would sometimes choose PGD as a method of selection. Couples, therefore, should respect their hypothetical choices on a principle similar to that of patient autonomy. My thesis shows that no matter which moral doctrine couples subscribe to, they ought to conduct the PGD (...) procedure in the situations when it is impossible to implant all of the created embryos and if there is a significant risk for giving birth to a child with a serious condition.

The preventative paradigm of preconception care is receiving increasing attention, yet its boundaries remain vague in three respects: temporally; agentially; and instrumentally. Crucially, it remains unclear just who is to be considered a ‘potential parent’, how soon they should take up preconception responsibilities, and how weighty their responsibilities should be.

It is often argued that it does not matter morally whether biomedical interventions treat or prevent diseases or enhance nondisease traits; what matters is whether and how much they promote well-being. Therapy and enhancement both promote well-being, the argument goes, so they are not morally distinct but instead continuous. I provide three reasons why this argument should be rejected when it is applied to choices concerning the genetic makeup of future people. First, it rests on too simple a conception of (...) the badness of disease. Second, it wrongly assumes that disease avoidance and enhancement can proceed with similar accuracy. Third, it overlooks that disease avoidance tends to be more urgent than enhancement from the point of view of distributive justice. Although none of these reasons establishes a firm therapy-enhancement distinction, they show that a continuum model is not an attractive alternative. (shrink)

In Enhancing Evolution: The Ethical Case for Making Better People (2007), John Harris argues that a proper concern for the welfare of future human beings implies that we are morally obligated to pursue enhancements. Similarly, in “Procreative Beneficience: Why We Should Select The Best Children” (2001) and in a number of subsequent publications, Julian Savulescu has suggested that we are morally obligated to use genetic (and other) technologies to produce the best children possible. In this paper I argue that if (...) we do have such obligations then their implications are much more radical than either Harris or Savulescu admit. There is an uneasy tension in the work of these authors, between their consequentialism and their (apparent) libertarianism when it comes to the rights of individuals to use—or not use—enhancement technologies as they see fit. Only through a very particular and not especially plausible negotiation of the tension between their moral theory and their policy prescriptions can Harris and Savulescu obscure the fact that their philosophies have implications that most people would find profoundly unattractive.

The article explores some of the issues that have arisen in the discourse on pharmaceutical cognitive enhancement (PCE), that is, the use of stimulant drugs such as methylphenidate, amphetamine and modafinil by healthy individuals of various populations with the aim of improving cognitive performance. Specifically, we explore the presumed sizes of existing PCE user populations and the policy actions that have been proposed regarding the trend of PCE. We begin with an introductory examination of the academic stances and philosophical issues (...) involved in defining PCE. We then focus on an examination of the population sizes of presumed current PCE users that have been listed in the academic literature on PCE, on presuppositions, which have been problematized by some authors as based on anecdotal or misinterpreted survey data. We follow this with an empirical examination of a potential PCE user population in a national context (students at the University of Ljubljana in Slovenia). We then proceed to examine the regulatory options proposed in the academic literature to address PCE, finally comparing them with an empirical overview of the policy recommendations on PCE produced in the multinational context of several national ethics advisory bodies (EABs) in Europe. Our main conclusion is that there is still little debate among the national EABs on what type of public policy responses, if any, are needed to address PCE in European countries, and that the issues they do address are similar to those discussed and proposed in the academic articles on PCE.

Some have objected to human enhancement on the grounds that it violates the autonomy of the enhanced. These objections, however, overlook the interesting possibility that autonomy itself could be enhanced. How, exactly, to enhance autonomy is a difficult problem due to the numerous and diverse accounts of autonomy in the literature. Existing accounts of autonomy enhancement rely on narrow and controversial conceptions of autonomy. However, we identify one feature of autonomy common to many mainstream accounts: reasoning ability. Autonomy can then (...) be enhanced by improving people’s reasoning ability, in particular through cognitive enhancement; given how valuable autonomy is usually taken to be, this gives us extra reason to pursue such cognitive enhancements. Moreover, autonomy-based objections will be especially weak against such enhancements. As we will argue, those who are worried that enhancements will inhibit people’s autonomy should actually embrace those enhancements that will improve autonomy. (shrink)

The evaluation of whether an animal has a life worth living (LWL) has been suggested as a useful concept for farm animal policymaking. But there are a number of different ways in which the concept could be applied. This paper attempts to identify and evaluate candidate ethical principles based on the concept. It suggests that an appropriate principle by which to apply the concept is one that (1) is framed in terms of preventing an animal having a life worth avoiding (...) (LWA), rather than ensuring they have LWL, (2) is based on a prospective, rather than retrospective, concept of a life’s worth, and (3) relates to both the perpetuation and creation of an animal at all times during its life. The paper concludes by endorsing an overarching principle that no animal should be unreasonably caused to be, or allowed to remain, in a position of having a prospective LWA. (shrink)

Assisted reproduction using donor gametes is a procedure that allows those who are unable to produce their own gametes to achieve gestational parenthood. Where conception is achieved using donor sperm, the child lacks a genetic link to the intended father. Where it is achieved using a donor egg, the child lacks a genetic link to the intended mother. To address this lack of genetic kinship, some fertility clinics engage in the practice of matching the ethnicity of the gamete donor to (...) that of the recipient parent. The intended result is for the child to have the phenotypic characteristics of the recipient parents. This paper examines the philosophical and ethical problems raised by the policy of ethnic matching in gamete donation. I consider arguments for the provision of ethnic matching based on maximising physical resemblance and fostering ethnic identity development. I then consider an argument against ethnic matching based on the charge of racialism. I conclude that while the practice of ethnic matching in gamete donation could promote positive ethnic identity development in donor-conceived children from historically subjugated ethnic minorities, it also risks endorsing the problematic societal attitudes and assumptions regarding ethnicity that enabled such subjugation in the first place.

Human Enhancement Technology ranges from the commonplace, such as education, to the futuristic, with possible future developments including genetic modification or direct computer-brain interfaces. Public policies governing the supply of these technologies have the potential to greatly increase or mitigate economic inequality. Due to this potential harm, many have suggested prohibition of further developments of enhancement technologies. However, prohibition would in ineffective at preventing this harm and also would also prevent many positive aspects of enhancement technologies. On the other hand, (...) due to the expected benefits, many have suggested allowing access and development within a free-market system. However, this has the potential to increase inequality beyond acceptable levels. Consequently, Government policies must provide appropriate funding and regulation in order for these technologies to be distributed fairly to provide the most benefits and prevent the worst outcomes.
