Opponents of destructive embryo research, such as embryo rightists, as well as proponents accept that natural reproduction is permissible. There is an alternative to natural reproduction—to remain childless. John Harris began this series of articles by asking, what does a commitment to the permissibility of natural reproduction entail? Harris has argued that a commitment to the permissibility of natural reproduction entails a commitment to the permissibility of destructive embryo research. Julian Savulescu has (...) denied this. However, there are significant areas in which our views have converged. (shrink)

In this paper, we are concerned with the ethical implications of the distinction between natural reproduction and reproduction that requires assistance. We argue that the current practice of enforcing regulations on the latter but not on the former means of reproduction is ethically unjustified. It is not defensible to tolerate parental ignorance or abuse in natural reproduction and subsequently in natural parenting, whilst submitting assisted reproduction and parenting to invasive scrutiny. Our proposal (...) is to guarantee equal treatment to people engaging in either form of reproduction or parenting. (shrink)

John Harris gives a comprehensive and generally valid defense of embryo research. Although nearly all his arguments are valid, one—the argument comparing natural reproduction to embryo research—is problematic in several important ways. I focus here on that argument.

Whilst the choice of becoming a parent in the natural way is unregulated all over Europe (and proposals of regulation raise vehement objections), most European countries have (either legal or professional) regulations imposing criteria that people must satisfy if they wish to gain access to assisted reproduction and parenting. These criteria may include relationship status, age, sexual orientation, financial stability, health, and willingness to attend parenting classes. The existence of regulations in this area is largely accepted, and the (...) objections raised usually concern the suitability of specific criteria rather than the legitimacy of imposing criteria at all. The inequality (if unsupported) could be solved by requiring both prospective natural and assisted parents to satisfy the same criteria (with some qualifications specified below) and, more importantly, to be subject to the same degree of monitoring, regardless of the way in which they became parents. Often people argue that proposals to regulate natural reproduction revive dreaded eugenic policies of the past, and that their implementation would violate some of our most cherished interests and rights: in particular the interest in becoming a parent and the right to reproduction and parenting. However, the same interests and rights are not equally safeguarded when one needs assistance to become a parent, and proposals to reduce the extent to which prospective parents requiring assistance are scrutinized are unpopular. In this paper we challenge the alleged justification of the current practices, and we show that there are serious inconsistencies in the treatment of, respectively, people who become parents naturally and people who require assistance to become parents. Thus, we propose that regulation of reproduction and parenting be revised in such a way as to eliminate the inconsistencies. (shrink)

Catholic natural law has had a long and evolving interest in bioethics. Thomas Aquinas left natural law a legacy of great flexibility in evaluating goods within a whole life. He also bequeathed to the Church the basis for an abolutism on sexual issues. Modern reproductive medicine and a deeper understanding of human freedom have reopened these issues. The Vatican has developed new, holistic arguments to proscribe reproductive interventions, but critics remain unconvinced that marital relationships and goods have been (...) adequately evaluated. The resolution of this debate will require further experience and reflection. Keywords: Thomas Aquinas, freedom, natural law, reproductive ethics CiteULike Connotea Del.icio.us What's this? (shrink)

Certain restrictions on public funding for assisted reproductive technology (ART) are articulated and defended by recourse to a distinction between medical infertility and social infertility. We propose that underlying the prioritization of medical infertility is a vision of medicine whose proper role is to restore but not to improve upon nature. We go on to mark moral responses that speak of investments many continue to make in nature as properly an object of reverence and gratitude and therein (sometimes) a source (...) of moral guidance. We draw on the work of Ludwig Wittgenstein in arguing for the plausibility of an appeal to nature in opposition to the charge that it must contain a logical fallacy. We also invite consideration of the moral plausibility of some appeal to nature. Finally, we examine what follows in the case of ART. Should medicine respect as natural limits that should not be overcome: the need for a man and a woman in reproduction; menopause; and even declining fertility with age? We must first ask ourselves to what degree we should defer to nature in the conduct of medicine, at least in the particular if not the general case. This will involve also asking ourselves what we think is natural and in what instances and spirit might we defy nature. Divergent opinions and policies concerning who should receive ART treatment and public funding are more easily understood in view of the centrality, complexity and fundamental nature of these questions.

Transformations in the economy have led to significant changes in the recreational sphere of the macroregion. The introduction of market relations in the process of use, conservation, improvement and protection of natural recreational resources in the Carpathian macroregion has significantly exacerbated the solution of environmental, social and economic problems. Reproduction of natural resources in the recreational sphere requires the introduction of new theoretical and methodological principles. First of all, it concerns the qualitative distribution of resources suitable for (...) the organization of recreation between the consumer spheres. This is the conceptual basis for establishing the limits of their use in order to prevent degradation and exhaustion. Exploring the ecological and economic principles of reproduction of natural recreational resources, two areas are identified: intra-industry, which characterizes the reproduction of studied resources within the recreational economy and intersectoral, which relates to the reproduction of attractive natural resources, which at the time of study are subject to economic activities. It is scientifically substantiated that the institutes functioning in the recreational sphere of the macroregion do not provide the proper solution of the set tasks. Institutional changes are needed, taking into account such prerequisites as: transition to a market model of management; intensification of the development of the recreational sphere in the conditions of insufficient experience; ecological situation in the macroregion; environment for the development of recreation in the context of globalization.

This paper analyzes recent attempts to reject reproduction with lineage formation as a necessary condition for evolution by means of natural selection :560–570, 2008; Stud Hist Philos Sci Part C Stud Hist Philos Biol Biomed Sci 42:106–114, 2011; Bourrat in Biol Philos 29:517–538, 2014; Br J Philos Sci 66:883–903, 2015; Charbonneau in Philos Sci 81:727–740, 2014; Doolittle and Inkpen in Proc Natl Acad Sci 115:4006–4014, 2018). Building on the strengths of these attempts and avoiding their pitfalls, it is (...) argued that a robust formulation of evolution by natural selection without reproduction can be established. The main contribution of this paper is a reformulation of Lewontin’s three principles stating that minimal evolution by natural selection occurs when two conditions are met in a population: fitness-related variation and memory. Paradigmatic evolution by natural selection, which can generate adaptations, takes place when an additional condition is present, namely regeneration. (shrink)

In this paper I argue that some human reproductive genome editing interventions can be therapeutic in nature, and thus that it is false that all such interventions just create healthy individuals. I do this by showing that the conditions established by a therapy definition are met by certain reproductive genome editing interventions. I then defend this position against two objections: (a) reproductive genome editing interventions do not attain one of the two conditions for something to be a therapy, and (b) (...) some reproductive genome editing interventions are therapeutic but in a nonstandard way. In the Conclusion I call for a more nuanced discussion of the nature of reproductive genome editing interventions. (shrink)

Traditionally reproduction, gestation and childbirth have all been regarded as being primarily a woman's domain. As natural reproduction occurs inside a woman's body, respect for autonomy and bodily integrity requires the pregnant woman to have the conclusive say over the fate of the embryo/fetus growing within her. Thus traditionally the ethics and law of reproduction is dominated by the importance of respecting women's reproductive choices. This paper argues that emerging technologies demand a radical rethink of ethics (...) and law in the area of reproduction. The creation and storing of embryos outside of a woman's body and maintaining a pregnancy in a brain dead woman's body and future possibilities such as ectogenesis and male pregnancy raise important issues that cannot simply be answered by appealing to the rights of women to control their bodies. There are those who argue that when reproduction or reproductive products exist outside of a woman's body each gamete donor should have an equal say over the fate of the embryo/fetus. Others, however, argue that giving an equal say to gamete donors in practice usually means allowing the male donor to veto the reproductive enterprise and this is unacceptable. As a result it has been suggested that women should be favoured when it comes to such reproductive choices. This paper examines both sides of this debate in order to answer the fundamental ethical and policy question: 'Is there any reason why women should necessarily retain control over reproduction rather than simply over their own bodies?'.

In much of the discourse of evolutionary theory, reproduction is treated as an autonomous function of the individual organism — even in discussions of sexually reproducing organisms. In this paper, I examine some of the functions and consequences of such manifestly peculiar language. In particular, I suggest that it provides crucial support for the central project of evolutionary theory — namely that of locating causal efficacy in intrinsic properties of the individual organism. Furthermore, I argue that the language of (...) individual reproduction is maintained by certain methodological conventions that both obscure many of the problems it generates and serve to actively impede attempts to redress those difficulties that can be identified. Finally, I suggest that inclusion of the complexities introduced by sexual reproduction — in both language and methodology — may radically undermine the individualist focus of evolutionary theory.

Reproduction is broadly recognised as fundamental to human flourishing. The presumptive priority of reproductive freedom forms the predominant position in the literature, translating in the non-sexual reproductive realm as an almost inviolable right to access assisted reproductive technology (ART). This position largely condemns refusal or restriction of ART by clinicians or the state as discriminatory. In this paper, I critically analyse the moral rights individuals assert in reproductive pursuit to explore whether reproductive rights entitle hopeful parents to ART. I (...) demonstrate that none of the protected actions performed, or entitlements generated are sui generis ‘reproductive’ rights, leading to the claim that there is no such thing as a right to reproduce. Under scrutiny, the reproductive right is a far narrower and weaker rights assertion than is recognised in the literature. I argue that the predominant position is grounded in a fundamental misunderstanding of the scope and strength of reproductive claims.I also highlight a significant conceptual inconsistency in the literature. On one hand, there is broad consensus that reproductive rights are predominantly negative, yet access to fertility treatment is framed as a component of the right. This wrongly contorts the negative nature of reproductive rights into a positive claim-right to ART. I conclude that this mistakenly frames ART access as sitting within the scope of reproductive freedom. I offer a revised conceptual paradigm of reproductive rights that has important clinical and policy implications for the provision and regulation of ART. (shrink)

Giulia Cavaliere disagrees with claims that ectogenesis will increase equality and freedom for women, arguing that they often ignore social context and consequently fail to recognise that ectogenesis may not benefit women or it may only benefit a small subset of already privileged women. In this commentary, I will contextualise her argument within the broader cultural milieu to highlight the pattern of reproductive advancements and technologies, such as egg freezing and birth control, being presented as the panacea for women’s inequality. (...) While these advancements and technologies can benefit women, I argue medicine is not the best tool to ‘cure’ social problems and should not be co-opted as an agent of social change. Systemic social changes, not just technomedical approaches, are needed to address the root of gender inequality, which is social in nature, not medical. (shrink)

In China, neither reproduction and parenthood by lesbian couples nor their marital status are regulated or protected by law. In 2020, the first legal dispute in China involving a lesbian couple over custody of their joint baby was heard in court. This study examines the legal and ethical issues that lesbian couples confront when they decide to give birth to a child of their own. These challenges begin with regulatory restrictions on their lawful access to assisted reproductive technology and (...) extend to gaps in the legal establishment of parenthood. We found that the lack of access to legitimate reproductive assistance for lesbian couples in China has caused them to make efforts to circumvent laws and regulations to have a child. However, the legislative gaps later led to ethical dilemmas when resolving disputes over parenthood. This study discusses different accounts of establishing and determining natural parenthood in China and concludes by pointing out the urgent need for change in legislative and sociocultural attitudes toward both assisted reproductive technology and same‐sex relationships, mapping the way forward for lesbian couples to obtain better protection of procreation and parenthood before their marriage is culturally accepted and finally legalized.

Reproductive genetic carrier screening (RCS), when offered to anyone regardless of their family history or ancestry, has been subject to the critique that it is a form of eugenics. Eugenics describes a range of practices that seek to use the science of heredity to improve the genetic composition of a population group. The term is associated with a range of unethical programmes that were taken up in various countries during the 20th century. Contemporary practice in medical genetics has, understandably, distanced (...) itself from such programmes. However, as RCS becomes more widespread, gains public funding and uses expanded gene panels, there are concerns that such programmes could be perceived as eugenic either in intent or outcome. The typical response to the eugenics critique of RCS is to emphasise the voluntary nature of both participating in screening and making subsequent reproductive choices. While safeguarding individuals’ freedom to choose in relation to screening is essential, we consider this response inadequate. By examining the specific ethical wrongs committed by eugenics in the past, we argue that to avoid the perception of RCS being a form of eugenics it is essential to attend to the broader normative context in which reproductive decisions occur. Furthermore, ethical RCS programmes must recognise and respond to their potential to shift societal norms that shape individual reproductive choices. (shrink)

The article discusses questions on the significance of blood relatedness in the context of identity arguments about artificial reproduction (AR). Kinship, origins, and biological connections are significant to human beings. The author explains that family relationships bear on the identity of human beings. Moreover, she emphasizes that once these principles are neglected, it is possible to create people in ways that threaten significant human bonds and alienate people who are naturally related spelling loss, confusion and grief for them.

The Canadian province of Quebec recently amended its Health Insurance Act to cover the costs of In Vitro Fertilization . The province of Ontario recently de-insured IVF. Both provinces cited cost-effectiveness as their grounds, but the question as to whether a public health insurance system ought to cover IVF raises the deeper question of how we should understand reproduction at the social level, and whether its costs should be a matter of individual or collective responsibility. In this article I (...) examine three strategies for justifying collective provisions in a liberal society and assess whether public reproductive assistance can be defended on any of these accounts. I begin by considering, and rejecting, rights-based and needs-based approaches. I go on to argue that instead we ought to address assisted reproduction from the perspective of the contractarian insurance-based model for public health coverage, according to which we select items for inclusion based on their unpredictability in nature and cost. I argue that infertility qualifies as an unpredictable incident against which rational agents would choose to insure under ideal conditions and that assisted reproduction is thereby a matter of collective responsibility, but only in cases of medical necessity or inability to pay. The policy I endorse by appeal to this approach is a means-tested system of coverage resembling neither Ontario nor Quebec's, and I conclude that it constitutes a promising alternative worthy of serious consideration by bioethicists, political philosophers, and policy-makers alike.

Reproductive medical technology has revolutionized the natural order of human procreation. Accordingly, some have celebrated its advent as a new and liberating determinant of kinship at the global level and advocate it as a right to reproductive health while others have frowned upon it as a vehicle for “guiltless exchange of sexual fluid” and commodification of human gametes. Religious voices from both Christianity and Islam range from unthinking adoption to restrictive use. While utilizing this technology to enable the married (...) couple to have children through the use of their own sexual material is welcome, the use of third party, surrogacy, and reproductive cloning are not in keeping with the sacrosanct principles of kinship, procreation through licit sexual intercourse, and social cohesiveness for building a cohesive family as uphold by both Christianity and Islam. To examine such larger issues emanating from these new ways of human procreation, beyond the question of legality, is a point which legal scholars in both Christianity and Islam, when issuing religious decrees, have not anticipated sufficiently. The article proposes to be an attempt to that end through a qualitative critical content analysis of selected literature written on the subject. (shrink)

In this revised edition with a new preface from the editor, leading scientists explain the nature and goals of `test tube' reproduction and genetic engineering, and their eugenic implications.

In Australia and other countries, certain groups of women have traditionally been denied access to assisted reproductive technologies . These typically are single heterosexual women, lesbians, poor women, and those whose ability to rear children is questioned, particularly women with certain disabilities or who are older. The arguments used to justify selection of women for ARTs are most often based on issues such as scarcity of resources, and absence of infertility , or on social concerns: that it “goes against nature”; (...) particular women might not make good mothers; unconventional families are not socially acceptable; or that children of older mothers might be orphaned at an early age. The social, medical, legal, and ethical reasoning that has traditionally promoted this lack of equity in access to ARTs, and whether the criteria used for client deselection are ethically appropriate in any particular case, are explored by this review. In addition, the issues of distribution and just “gatekeeping” practices associated with these sensitive medical services are examined. (shrink)

While the principles of reproductive justice are generally agreed upon in progressive reproductive political circles, other theoretical frameworks such as reparative justice can further foster the goals of the movement. In the literature, however, reparative justice has been insufficiently explored as it relates to reproductive injustice. My concern in this essay is therefore the development of conceptual architecture for understanding reproductive justice as reparative in nature. A reparative approach to reproductive ethics importantly takes up the demand to situate reproduction (...) within ongoing historical and sociopolitical contexts. It makes transparent the harms generated by an oppressive social order and the depths to which conditions must change for reproductive justice to emerge. To construct the relationship between reparative and reproductive justice, I employ Olúfemi Táíwò’s constructivist view of reparations as an ongoing, generative, and ultimately world-building project. For, if reproductive justice is about developing enabling conditions wherein folks can control their birthing options and parent in safe and healthy environments, then a constructivist reparative approach is necessary—one which takes seriously the accumulative harms of history and their relation to transforming social structures in the present.

In this paper, I argue that the development of an artificial womb is already well on its way. By putting together pieces of information arising from new scientific advances in different areas, (neo-natal care, gynecology, embryology, the human genome project and computer science), I delineate a distinctive picture, which clearly suggests that the artificial womb may become a reality sooner than we may think. Currently, there is a huge gap between the first stages of gestation (using in vitro fertilization) and (...) the 22nd week (inside the womb). At the present time this gap seems an insurmountable barrier for fully developing a fetus outside a natural womb – a notion better known as ectogenesis. The history of science however, suggests that impenetrable barriers are such only temporarily. It is just a matter of time (and due research) until someone – intentionally or by chance – accesses the right answer and finds a way to overcome existing obstacles. Despite misgivings that the case of the artificial womb presents too many barriers, it would be naïve to suppose things would happen any differently. I observe in this paper, that it is time to acknowledge the consequences of new developments in different areas of scientific research which are leading to the advent of an artificial womb; and I modestly suggest that we might initiate a discussion on this topic now, while we have still enough time to decide what we may want and why.

Les théories féministes de la reproduction ont été soumises à trois types d’objections : elles seraient soit fonctionnalistes, soit économicistes, ou biologisantes. Ces objections reposent sur un contresens concernant les notions marxistes de production et reproduction ainsi que sur une conception réifiée de la nature des sociétés capitalistes. De plus, ces objections ne sont pas capables de proposer une alternative convaincante et débouchent sur des impasses comme celles qui sont propres aux théories des systèmes double ou triple.

Abstract:This essay reviews the 2013 Human Life International (HLI) propaganda video, Central America and Mexico: Fighting for Life, Faith, and Family, which, we argue, illustrates the well-orchestrated counteroffensive against reproductive and sexual rights movements occurring in the region. First we summarize the film's key themes, including the assertion that Catholicism is fundamental to Mexican and Central American identities and that the international “pro-abortion movement” is waging war against Catholics. Second, we note the development of a new strategic alliance between Catholics (...) and evangelicals that relies on lay religious activists working in the fields of medicine, bioethics, law, and government. Third, we show how the video appeals to HLI donors by asking them to support crisis pregnancy centres, homes for unwed mothers, adoption programs, and “natural” fertility assistance. We argue that the film conspicuously ignores the consequences of abortion bans already in place in Nicaragua, El Salvador, and Honduras, and does not consider that what it terms “international pressures” also includes treaty obligations with the United Nations and Organization of American States. This essay offers insights into the strategies used by opponents of reproductive and sexual rights movements in Mexico and Central America. (shrink)

The prolepsis in Denis Villeneuve's Arrival emphasises the cyclical nature of the film's narrative and anchors human reproduction as a central theme. Pregnancy, the pregnant body, and the physical, experiential nature of birth, commonly heavily gendered in film, are misleading focal points in the narrative. The presence of the unborn as a subtext in the film problematises Iris Marion Young's notion of pregnant embodiment as a subjective lived-body experience. The viewer is encouraged to empathise with the complexity of birth, (...) life, and death as part of Louise's lived-body experience, but is finally confronted with the uncertainty of maternity, pregnancy and the unborn. When Barbara Duden calls the unborn foetus a “not-yet”, she describes the process by which the foetus achieves a legal status, and the precarious nature of ascribing life or personhood. The prolepsis, which punctuates the main narrative, emphasises the reversibility and irreversibility of life that does “not-yet” exist. Import... (shrink)

Until quite recently human reproduction was considered an entirely natural process, and the ethics of reproduction were governed more by cultural mores and religious strictures than by any serious philosophical or empirical inquiry. However, more recently reproductive ethics has exploded as a field for several reasons. At a cultural level, many things taken for granted a generation ago, including the increasing medicalization of birth and the heteronormative two-parent nuclear family, have been challenged, and new possibilities have arisen (...) from these now contested ideas. It is important to remember that the explosion of reproductive ethics is as much from new thinking as it is from new technologies, and, at least in regard to reproductive possibilities for the LGBTQ community, it may well be fair to say that it is our new thinking that then led to new technological explorations.

The fundamental postulate of sociobiology is that individuals exploit favorable environments to increase their genetic representation in the next generation. The data on fertility differentials among contemporary humans are not cotvietent with this postulate. Given the importance ofHomo sapiensas an animal species in the natural world today, these data constitute particularly challenging and interesting problem for both human sociobiology and sociobiology as a whole.The first part of this paper reviews the evidence showing an inverse relationship between reproductive fitness and (...) “endowment” in contemporary, urbanized societies. It is shown that a positive relationship is observed only for those cohorts who bore their children during a unique period of rising fertility, 1935–1960, and that these cohorts are most often cited by sociobiologists as supporting the central postulate of sociobiology. Cohorts preceding and following these show the characteristic inverse relationship between endowment and fertility. The second section reviews the existing so-ciobiological models of this inverse relationship, namely, those of Barkow, Burley, and Irons, as well as more informal responses among sociobiologists to the persistent violation of sociobiology's central postulate, such as those of Alexander and Dawkins. The third section asks whether the goals of sociobiology, given the violation of its fundamental postulate by contemporary human societies, might not be better thought of as applied rather than descriptive, with respect to these societies. A proper answer to this question begins with the measurement of the pace and direction of natural selection within modern human populations, as compared to other sources of change. The vast preponderance of the shifts in human trait distributions, including the IQ distribution, appears to be due to environmental rather than genetic change. However, there remains the question of just how elastic these distributions are in the absence of reinforcing genetic change. (shrink)

Studies of the association between wealth and fertility in industrial populations have a rich history in the evolutionary literature, and they have been used to argue both for and against a behavioral ecological approach to explaining human variability. We consider that there are strong arguments in favor of measuring fertility (and proxies thereof) in industrial populations, not least because of the wide availability of large-scale secondary databases. Such data sources bring challenges as well as advantages, however. The purpose of this (...) article is to illustrate these by examining the association between wealth and reproductive success in the United States, using the National Longitudinal Study of Youth 1979. We conduct a broad-based exploratory analysis of the relationship between wealth and fertility, employing both cross-sectional and longitudinal approaches, and multiple measures of both wealth (income and net worth) and fertility (lifetime reproductive success and transitions to first, second and third births). We highlight the kinds of decisions that have to be made regarding sample selection, along with the selection and construction of explanatory variables and control measures. Based on our analyses, we find a positive effect of both income and net worth on fertility for men, which is more pronounced for white men and for transitions to first and second births. Income tends to have a negative effect on fertility for women, while net worth is more likely to positively predict fertility. Different reproductive strategies among different groups within the same population highlight the complexity of the reproductive ecology of industrial societies. These results differ in a number of respects from other analyses using the same database. We suggest this reflects the impossibility of producing a definitive analysis, rather than a failure to identify the “correct” analytical strategy. Finally, we discuss how these findings inform us about (mal)adaptive decision-making. (shrink)

In this article I argue that we should pay extra attention to the ecological dimension of natural selection. By this I mean that we should view natural selection primarily as acting on the outcomes of the interactions organisms have with their environment, which influences their relative reproductive output. A consequence of this view is that natural selection is not sensitive to what system of inheritance ensures reoccurrences of organism-environment interactions over generations. I end by showing the consequences (...) of this view when looking at how processes like niche construction and the Baldwin effect relate to natural selection. (shrink)

Significant developments in medical research and technology have meant that the process of reproduction is increasingly affected by the consumption of a variety of services and goods. Individuals intervene in their own reproductive processes as they eat particular foods, take particular drugs and avail themselves of diagnostic and reproductive services. Although such developments have been analysed by feminists in terms of their ethical consequences or their contribution to the commodification of reproduction, they have not been evaluated in terms (...) of their contribution to reproductive consumption. This article argues that we can avoid the reductiveness of critiques of commodified reproduction by developing a conceptual framework of reproductive consumption. Thinking through reproductive consumption also enables feminist analysis to expand our understanding of the gendered aspects of consumption. Most feminist work on consumption practices has focused on the domestic sphere as a site of consumption or on the role of sex and sexuality in promoting consumption. This article's analysis of reproductive consumption adds to this work by revealing ways in which biological reproduction itself is a site of consuming desires and needs, and is permeated by socio-economic forces. In developing a theoretical framework for analysing reproductive consumption, this article argues that consumption produces adaptive value as an object of exchange is acquired and adapted in order to satisfy some need or desire. In making this argument I draw on O'Brien, who argued that reproduction produces syntheticvalue by synthesizing reason and nature in bringing another human being into the world. In doing so she used Marx's method of extracting the concept of commodity value from capitalist exchange relations. Similarly, I analyse the relations of consumption in order to distil a value that is specific to consumption. Reproductive consumption identifies the reproductive consumer as someone who adapts objects of consumption to her own reproductive needs and desires as she negotiates her reproductive nature. Thinking about reproduction and consumption in terms of each other helps us to identify how reproduction is brought about through a taste for particular goods and services, and how consumption works through the reproductive, as well as the sexual, body.

In Northern Canada, Indigenous mixed economies persist alongside and in resistance to capital accumulation. The day-to-day sites and processes of colonial struggle, and, in particular, their gendered nature, are too often ignored. This piece takes an anti-colonial materialist approach to the multiple labours of Indigenous women in Canada, arguing that their social-reproductive labour is a primary site of struggle: a site of violent capitalist accumulation and persistent decolonising resistance. In making this argument, this piece draws on social-reproduction feminism, and (...) anti-racist, Indigenous and anti-colonial feminism, asking what it means to take an anti-colonial approach to social-reproduction feminism. It presents an expanded conception of production that encompasses not just the dialectic of capitalist production and reproduction, but also non-capitalist, subsistence production. An anti-colonial approach to social-reproduction feminism challenges one to think through questions of non-capitalist labour and the way different forms of labour persist relationally, reproducing and resisting capitalist modes of production.

The majority of embryos created in natural reproduction die spontaneously within a few weeks of conception. Some have argued that, therefore, if one believes the embryo is a person (in the normative sense) one should find ‘natural’ reproduction morally problematic. An extension of this argument holds that, if one accepts embryo deaths in natural reproduction, consistency requires that one also accepts embryo deaths that occur in (i) assisted reproduction via in vitro fertilisation (IVF) (...) and (ii) embryo research. In a recent paper in this journal, Timothy Murphy criticises both the initial argument and its extension. Murphy argues that double-effect reasoning can justify embryo deaths both in natural reproduction and IVF, but not in embryo research. Thus, according to Murphy, one can, without being inconsistent, (1) believe the embryo is a person and accept natural reproduction and IVF, and (2) accept natural reproduction and IVF, while rejecting embryo research on the ground that it involves embryo deaths. I show that Murphy's argument is problematic because double effect cannot justify embryo deaths in standard IVF practices. The problem is that the proportionality criterion of double effect is not met by such practices. Thus, Murphy's argument fails to support (1) and (2). An implication of his argument failing to support (2) is that it does not defeat the position I have defended in the past—that if one accepts standard IVF practices one should also accept embryo research, including research with embryos created solely for that purpose.

Patterns of three variables of reproductive strategies in male New World primates are examined: (i) how males obtain access to potential mates; (ii) how males obtain actual mating opportunities; and (iii) how males affect infant survival and female reproductive success. Male opportunities to associate with females, whether by remaining in their natal groups, dispersing and forming new groups, or dispersing and taking over or joining established groups, are strongly influenced by local population densities and correlate with female reproductive rates and (...) the extent of female reproductive seasonality and synchrony. Differences in male mating success are affected by female accessibility, whether male-male and male-female relationships are hierarchical or egalitarian, and whether female reproduction is seasonally restricted. Patterns of male behavior toward infants, characterized as active assistance, overt interference, or benign tolerance, appear to co-vary with differences in the degree to which males can affect female reproductive rates.These qualitative analyses suggest that the reproductive strategies of male New World primates can be classified along a continuum ranging from conservative to daring depending on whether female reproductive rates are relatively slow or fast and whether reproduction is strongly or weakly linked to seasonal ecological variables. Males adopt the conservative strategy of staying in their natal groups, forfeiting exclusive mating opportunities, and treating infants with tolerance when female reproduction is constrained by ecological factors. Conversely, males adopt the more daring strategy of dispersing and competing when potential payoffs through their ability to affect female reproduction are high. (shrink)

This paper urges reconsideration of analyses of the alternatives to reproductive uterus transplantation (UTx). I focus here specifically on the adoption alternative. Importantly, my purpose is not to oppose UTx provision. Rather, it is to propose ways in which ethical analysis and provision of UTx can potentially accommodate the concerns discussed here. I argue that the adoption alternative to UTx is too readily dismissed, and that this is a dismissal with significant moral costs. I suggest that the radical nature of (...) UTx as a form of assisted reproduction calls for an equivalently radical socio‐moral agenda for reform and transformation of adoption law, policy and practice, as well as of the norms that prevail within our presently strongly bio‐normative reproductive context. In doing so I widen the ethical frame of responsible provision of assisted reproduction to encompass not just obligations towards donors and recipient, but also our broader social responsibilities to ensure that we are doing our best to meet the significant needs of some of the most vulnerable members of our society.

Nature and Mortality is a challenging look at some of the major public issues of our time through the eyes of one of our most influential and probing liberal humanists. It is a frank account on where we stand today on such controversial matters as human embryology, genetic engineering, euthanasia and abortion. Warnock's views may seem like a red rag to a bull to some, but her contribution to the debate is always stimulating. Enlivened by autobiographical anecdote and some delicious (...) side-swipes, Nature and Mortality is Mary Warnock at her most perceptive, wise and entertaining. (shrink)

With growing awareness of a crisis in pollinator health, the practice of urban hobbyist beekeeping has grown in Canada with practitioners arguing that this activity can help to foster healthier honey bees and more mindful beekeeping practices. However, urban hobbyist beekeepers have been critiqued for encouraging improper beekeeping practices and over-saturation of honey bees in cities. Drawing on a multispecies ethnography based in London, Ontario and Toronto, including participant observation with the Toronto Beekeeping Collective and the London Urban Beekeeping Collective (...) and interviews with 26 urban beekeepers, I argue that urban hobbyist beekeepers develop a sensuous and embodied relationship with honey bees that typifies playful work. By integrating participant perspectives with social reproduction theory, I demonstrate that the playful work of urban hobbyist beekeeping allows practitioners to engage with non-human nature outside of the constraints of capitalist labour regimes, enabling the expression of delight, enchantment, and curiosity. This relationship between beekeepers and honey bees encourages the development of bee-centred practices in which the preferences and physiological needs of the bees are consciously put ahead of the needs of the beekeeper. The possibility for honey bee flourishing is increased significantly when bee-centred beekeeping is coupled with integrated pest management. (shrink)

Several problems with Hegel’s conception of the organism in the Encyclopaedia are due to the separation between individual life in Nature and the universal life of the Concept. This discontinuity between ontogenesis and phylogenesis in his dialectics of organic life will be studied here by following his presentation of physiological development, especially reproduction, and by reconstructing the historical model he criticizes—Leibniz’s organic machines and their development in Buffon’s Natural History—a model that was also of crucial importance to the (...) philosophy of nature of Schelling and his followers.

Alex Pruss argues that romantic love is a basic form of human love that is properly fulfilled in sex oriented towards reproduction. As a result, homoerotic sexual activity cannot obtain the proper consummation and therefore involves misunderstanding the other person’s nature and the possibility of union with them. Although same-sex sexual activity may feel like a consummation of romantic love, it is wrong to generate such a false experience in oneself or another. Presented is an apparent dilemma for Pruss’s (...) thesis suggesting that either both postmenopausal homosexuals and postmenopausal heterosexuals ought to be allowed to marry for their romantic love is not dysfunctional despite not being oriented towards reproduction, or that matrimony is inappropriate for both groups. I suggest avoiding the dilemma in either of two ways that would allow Pruss to distinguish the infertility of homosexual couples from the infertility of post-menopausal women. (shrink)
