Most people agree that inflicting unnecessary suffering upon animals is wrong. Many fewer people, including among ethicists, agree that painlessly killing animals is necessarily wrong. The most commonly cited reason is that death (without pain, fear, distress) is not bad for them in a way that matters morally, or not as significantly as it does for persons, who are self-conscious, make long-term plans and have preferences about their own future. Animals, at least those that are not persons, lack a morally (...) significant interest in continuing to live. At the same time, some argue that existence itself can be good, insofar as one’s life is worth living. For animals, a good life can offset a quick, if early, death. So, it seems to follow that breeding happy animals that will be (prematurely) killed can be a good thing overall. Insofar as slaughter and sale makes it economically sustainable to raise new ones, who would otherwise not exist, raising and killing animals for food who will have lives worth living is good overall. It benefits them as well as consumers, and makes the world better by adding to the sum of happiness. The process of raising and killing animals with positive welfare produces a sequence of replacement that maintains or increases overall welfare, all else being equal (assuming in particular no overall negative impact on the welfare of other parties). Call this the Replaceability Argument (RA) and the ensuing controversy the Replaceability Problem (RP). This is a problem at the crossroads of the ethics of killing, agricultural ethics, procreation ethics, and population ethics. (shrink)

Alvin Plantinga has recently turned his attention to materialism. More precisely, he has turned his attention to the thesis that philosophers of mind call materialism.[i] This thesis can be variously formulated. In this essay, I will take “materialism” to be the conjunction of the following two theses.

Animal replaceability is supposed to be a feature of some consequentialist theories, like Utilitarianism. Roughly, an animal is replaceable if it is permissible to kill it because the disvalue thereby caused will be compensated by the value of a new animal’s life. This is specially troubling since the conditions for such compensation seem easily attainable by improved forms of raising and killing animals. Thus, grounding a strong moral status of animals in such theories is somewhat compromised. As is, consequently, (...) their position as an alternative to rights-based theories in animal ethics. Recognising this, some utilitarians tried to disassociate utilitarianism and replaceability. I will here add my voice to this project. However, instead of seeing the culprit in the usual suspects (hedonism, maximisation or the total view), I advance a new proposal. After identifying that the compensating value for a disvaluable action has to be its consequence, I present a restriction on consequences: consequences of sequences of actions cannot be consequences of the isolated actions in the sequences. Given this, the main argument is simple: killing an animal is permissible only if the the value of the new animal’s life is a consequence of the killing; but this value is a consequence of a sequence of actions which involves the killing plus some additional actions; therefore, since, via the restriction, such value is not a consequence of the killing, it is irrelevant to its normative status. I then present two further motivations for the restriction: firstly, it prevents the value of conditional actions from trivially influencing the value of the actions on which they are conditional; secondly, it is useful – even if not a complete solution – to reply other objections to consequentialism: the accordion effect of action and the cluelessness problem. I finally consider a couple of objections. (shrink)

In February 2015 the UK became the first country to legalise high-profile mitochondrial replacement techniques, which involve the creation of offspring using genetic material from three individuals. The aim of these new cell reconstruction techniques is to prevent the transmission of maternally inherited mitochondrial disorders to biological offspring. During the UK debates, MRTs were often positioned as a straightforward and unique solution for the ‘eradication’ of mitochondrial disorders, enabling hundreds of women to have a healthy, biologically-related child. However, many questions (...) regarding future applications and potential users remain. Drawing on a current qualitative study on reproductive choices in the context of mitochondrial disorders, this article illustrates how the potential limitations of MRTs have been obscured in public debates by contrasting the claims made about the future beneficiaries with insights from families affected by mitochondrial disorders and medical experts. The analysis illuminates the complex choices with which families and individuals affected by mitochondrial disorders are faced, which have thus far remained invisible. An argument is presented for improved information for the public as well as an intensification of critical empirical research around the complex and specific needs of future beneficiaries of new reproductive biotechnologies.

Singer’s much-discussed replaceability argument states that non-self-conscious animals may be killed and replaced by new animals that will lead equally valuable lives. If sound, this argument can be used to justify the cycle of raising and killing animals for food. Thus, many have argued that Singer’s theory, and utilitarianism in general, while committed to this argument, offers inadequate protection to animals. However, some utilitarians reject the argument and Singer himself was rather tentative in preventing its (...) additional application to self-conscious beings. This tension, within utilitarianism, about how to best deal with the argument is the core of what I call ‘the problem of replaceability’. My main goal here is to provide a precise description of this problem. Firstly, I distinguish between the general question of replacement permissibility and the specific question of whether (a certain version of) utilitarianism implies the replaceability argument. Focusing on the specific question I set the problem apart from other known objections to utilitarianism, like the value receptacles objection and some replacement-like difficulties. I also compare two versions of the replaceability argument and advance a better one. Finally, I point out how different interpretations of the argument affect the way out of the problem. I hope this understanding of the problem offers helpful insight to possible solutions and to further investigate its importance to animal food production and animals’ moral status. (shrink)

Jürgen Habermas is regarded as a central bioconservative commentator in the debate on the ethics of human prenatal genetic manipulations. While his main work on this topic, The Future of Human Nature, has been widely examined in regard to his position on prenatal genetic enhancement, his arguments regarding prenatal genetic therapeutic interventions have for the most part been overlooked. In this work I do two things. First, I present the three necessary conditions that Habermas establishes for a prenatal genetic manipulation (...) to be regarded as morally permissible. Second, I examine if mitochondrial replacement techniques meet these necessary conditions. I investigate, specifically, the moral permissibility of employing pronuclear transfer and maternal spindle transfer. I conclude that, according to a Habermasian perspective on prenatal genetic manipulation, maternal spindle transfer and pronuclear transfer are morally impermissible. Maternal spindle transfer is, in principle, morally permissible, but only when we have beforehand preselected a sperm and an egg for our reproductive purpose. These findings are relevant for bioconservatives, both for those who hold a Habermasian stance and for those who hold something akin to a Habermasian stance, because they answer the question: what should bioconservatives do regarding mitochondrial replacement techniques? In fact, the answer to this question does not only normatively prescribe what bioconservatives should do in terms of their personal morality, but it also points towards what kind of legislation regulating mitochondrial replacement techniques they should aim at.

Many criminal lawyers should expect that, were they to not defend a certain client, someone no less capable would do so. It is morally wrong for such attorneys to defend defendants who should be punished. This is true even if we grant that the defendant’s right to be defended outweighs any rights that might be infringed by the defense and that the benefits of defending are greater than the harm. Nor does this argument depend on any particular view of (...) punishment. The fact that the attorney expects to be replaced by someone equally capable has an asymmetric effect on the reasons for and against defending. The reasons that justify defending become extremely attenuated by this expectation, no matter what they are, while the reasons against defending are much less affected, no matter what they are.

In order to be eligible for refugee status under the 1951 Refugee Convention, an individual must have a well-founded fear of persecution for reasons of race, religion, nationality, membership of a particular social group or political opinion. A major problem with this condition for refugee status is that it leaves significant protection gaps, for it is generally agreed that individuals fleeing indiscriminate violence or generalized harm do not satisfy this requirement. In this paper, I evaluate existing arguments both defending and (...) critiquing the persecution condition, and then outline my own account of the criteria that should replace it. I argue that my view is preferable to alternatives suggested in the literature because it satisfies three key desiderata: 1) it eliminates protection gaps; 2) it is feasible to implement in a world like ours; and 3) it preserves the importantly political nature of the institution of refugeehood.

A Foucauldian discourse analysis is employed to identify how our current understandings of menopause are culturally and historically determined by medical discourse. The polarity of the normal and the abnormal (pathological) became the crux of medical deliberation, where deviation from norms becomes the reason for intervention. Through manifold relations of power and the ‘struggle of knowledges’ medicine derives social authority, influencing social orthodoxies thus normalising menopausal women via discursive constructs. The course of nature in ageing women has been re‐categorised as (...) unnatural. In using the case of hormone therapy (HT) and the emergence of bio‐identical or natural hormones, while deconstructing the premises used in marketing both types of hormone therapy, the tenuousness of scientific claims about these hormones is revealed. Discourses on bio‐identical hormones (BHT) display a reliance on seemingly opposing naturalist and scientific arguments. Menopause, having been constructed as a deficiency disease, required initially chemical hormone replacement and now bio‐identical hormones replacing the mainstream medical solution. The idea of the postmenopausal state as diseased is perpetuated as the basis to suggest therapies to women. This paper suggests that although therapeutic in a few cases, hormone preparations are in fact potentially dangerous lifestyle drugs. (shrink)

The ethical theory underlying much of our treatment of animals in agriculture and research is the moral agency view. It is assumed that only moral agents, or persons, are worthy of maximal moral significance, and that farm and laboratory animals are not moral agents. However, this view also excludes human non-persons from the moral community. Utilitarianism, which bids us maximize the amount of good in the world, is an alternative ethical theory. Although it has many merits, including impartiality and the (...) extension of moral concern to all sentient beings, it also appears to have many morally unacceptable implications. In particular, it appears to sanction the killing of innocents when utility would be maximized, including cases in which we would deliberately kill and replace a being, as we typically do to animals on farms and in laboratories. I consider a number of ingenious recent attempts by utilitarians to defeat the killing and replaceability arguments, including the attempt to make a place for genuine moral rights within a utilitarian framework. I conclude that utilitarians cannot escape the killing and replaceability objections. Those who reject the restrictive moral agency view and find they cannot accept utilitarianism's unsavory implications must look to a different ethical theory to guide their treatment of humans and non-humans.

In this paper, we argue that lesbian couples who wish to have children who are genetically related to both of them should be allowed access to mitochondrial replacement techniques (MRTs). First, we provide a brief explanation of mitochondrial diseases and MRTs. We then present the reasons why MRTs are not, by nature, therapeutic. The upshot of the view that MRTs are non-therapeutic techniques is that their therapeutic potential cannot be invoked for restricting their use only to those cases where a (...) mitochondrial DNA disease could be ‘cured’. We then argue that a positive case for MRTs is justified by an appeal to reproductive freedom, and that the criteria to access these techniques should hence be extended to include lesbian couples who wish to share genetic parenthood. Finally, we consider a potential objection to our argument: that the desire to have genetically related kin is not a morally sufficient reason to allow lesbian couples to access MRTs. (shrink)

I propose that meat replacement is to meat, as drag is to gender. Meat replacement has the potential to shake concepts of meat, like drag does for gender. Meat replacements not only mimic meat but disclose how meat itself is performed in carnivorous culture -and show that it may be performed otherwise. My approach is inspired by the show RuPaul’s Drag Race. The argument builds on an imitation of Judith Butler’s work on gender performativity, performed by replacing ‘drag/ gender/ (...) sex/ heterosexism’ terms and relations in Butler’s text with ‘meat replacement/ meat/ species/ carnism’ ones.

In a recent paper –Lesbian motherhood and mitochondrial replacement techniques: reproductive freedom and genetic kinship– we argued that lesbian couples who wish to have children who are genetically related to both of them should be allowed access to mitochondrial replacement techniques (MRTs). Françoise Baylis wrote a reply to our paper –‘No’ to lesbian motherhood using human nuclear genome transfer– where she challenges our arguments on the use of MRTs by lesbian couples, and on MRTs more generally. In this reply we (...) respond to her claims and further clarify our position. (shrink)

The focus of this article is a question that has been neglected in debates about digitalization: Could machines replace human scientists? To provide an intelligible answer to it, we need to answer a further question: What is it that makes (or constitutes) a scientist? I offer an answer to this question by proposing a new demarcation criterion for science which I call “the discoverability criterion”. I proceed as follows: (1) I explain why the target question of this article is important, (...) and (2) show that it leads to a variant of the demarcation problem of science. (3) By arguing that it is probably an essential feature of science that we can make scientific discoveries, I suggest a novel way of dealing with this problem by proposing a new demarcation criterion. Before introducing it, (4) I analyze an exemplary case of a real scientific discovery, and (5) argue that scientific discovery processes have a general underlying structure. (6) I introduce my discoverability criterion for science and present my master argument that helps us understand which criteria have to be fulfilled in order to decide whether machines can replace human scientists or not. (7) I conclude by answering the article’s target question and bringing forward a take-home message. (shrink)

In her very interesting paper, “Peter Singer on Expendability,” L. A. Kemmerer re-examines Peter Singer’s utilitarian argument implying that some being are replaceable and the implications of this argument for the issue of treating animals. I attempt to defend Singer, and more generally utilitarianism , against these objections. I argue that, given a utilitarian outlook, some animals are indeed replaceable. But I also argue that few animals are replaceable in practice.

Many people are moved by the thought that if A is worse off than B, then if we can improve the condition of one or the other but not both that it is better to improve the condition of A. Egalitarians are buoyed by the prevalence of such thoughts. But something other than egalitarianism could be driving these thoughts. In particular, such thoughts could be motivated, instead, by a combination of the belief that desert should determine how people fare and (...) the belief that, for the most part, people are equally deserving. Shelly Kagan has pushed this line of argument, suggesting that desert should replace equality as a normative ideal. He argues that desert theory and egalitarianism often agree, and when they don’t intuition favors desert theory. A number of authors have offered responses to Kagan, including Serena Olsaretti, Fred Feldman, and Richard Arneson. However, I maintain that their responses are inadequate, primarily because they simply fail to capture the compelling intuitions that Kagan appeals to in making his case. There are other responses, however, and I consider three, each of which offers an egalitarian position that is compatible with Kagan’s most compelling intuitions. Thus, I maintain that Kagan has not sufficiently established that desert should replace equality as a normative ideal. There is still room for a genuinely egalitarian position, though Kagan’s reflections helpfully force egalitarians to further develop and refine their thinking. (shrink)

This essay argues that the flaws of just war theory should lead us to develop a new approach to living with others. Danielle Poe begins her argument with a description of just war theory and its failures. In the next section, Poe discusses the philosophy of Bat-Ami Bar On and Luce Irigaray in order to construct ethical commitments between people. These ethical commitments come from concrete acts of empathy, such as relationships of compassion, kindness, and hospitality. Finally, Poe considers (...) how these concrete acts can create conditions to prevent war. (shrink)

In a previous article, I argued that assessment requirements for transgender hormone replacement therapy (HRT) are unethical and dehumanising. A recent response published by theJournal of Medical Ethicscriticises this proposal. In this reply, I advance that their response misunderstood core parts of my argument and fails to provide independent support for assessment requirements. Though transition-related care may have similarities with cosmetic surgeries, this does not suffice to establish a need for assessments, and nor do the high rates of depression (...) and anxiety justify assessments, especially given the protective role HRT plays towards mental well-being.

Few discussions of the ethics of mitochondrial ‘replacement’ techniques have drawn significant ethical distinctions between the two approaches now legal in the U.K. However, Anthony Wrigley, Stephen Wilkinson and John Appleby have together argued that under some circumstances pronuclear transfer (PNT) may be in better ethical standing than maternal spindle transfer (MST). They base their conclusion on what they allege to be different implications of the techniques with respect to non‐identity considerations, which they ground on a version of origin essentialism. (...) I raise a series of problems for their argument, which have cautionary implications for invocations of origin essentialism that go beyond specialized debates regarding MST and PNT. I argue that (i) origin essentialism is a fragile foundation for non‐identity considerations; (ii) gametic essentialism, which Wrigley et al. believe licenses their claims, is more questionable than origin essentialism; (iii) gametic essentialism does not straightforwardly justify their conclusion; and (iv) their conclusion in fact relies on an especially dubious position that we can call chromosomal origin essentialism. No good reasons have yet been supplied to distinguish PNT from MST on ethical grounds, and one should be wary of basing claims with practical impact on fragile foundations relating to origin essentialism.

This paper is a complement to the recent wealth of literature suggesting a strong philosophical relationship between artificial life (A-Life) and artificial intelligence (AI). I seek to point out where this analogy seems to break down, or where it would lead us to draw incorrect conclusions about the philosophical situation of A-Life. First, I sketch a thought experiment (based on the work of Tom Ray) that suggests how a certain subset of A-Life experiments should be evaluated. In doing so, I (...) suggest that treating A-Life experiments as if they were just AI experiments applied to a new domain may lead us to see problems (like Searle’s “Chinese room”) which do not exist. In the second half of the paper, I examine the reasons for suggesting that there is a philosophical relationship between the two fields. I characterize the strong thesis for a translation of AI concepts, metaphors, and arguments into A-Life as the “global replacement strategy.” Such a strategy is only fruitful inasmuch as there is a strong analogy between AI and A-Life. I conclude the paper with a discussion of two areas where such a strong analogy seems to break down. These areas relate to eliminative materialism and the lack of a “subjective” element in biology. I conclude that the burden of proof lies with the person who wishes to import a concept from another discipline into A-Life, even if that other discipline is AI. (shrink)

A clinical trial on mitochondrial replacement therapy is currently being conducted and if this technique proves effective, National Health Service England will fund MRT through the highly specialised services funding stream. This paper considers whether MRT should be publicly funded by the NHS. Given the current financial pressure the NHS is experiencing, a comprehensive discussion is essential. There is yet to be a thorough discussion on MRT funding, perhaps because this is a small-scale issue and presumed to be covered by (...) the HSS budget. However, the source of funding has not been confirmed due to the trial’s incompletion. Upon its completion, reasoned decisions need to be made over the allocation of scarce NHS resources. It is therefore important to consider the following arguments in advance. Three arguments given against NHS funding of MRT will be evaluated. The first argument against NHS funding examines the HSS overspending its budget in an underfunded NHS, suggesting funding must be carefully reprioritised. Second, the ethical issue of allowing public access to a technique with insufficient evidence behind it will be explored. The final point considers the option of privately funding MRT and how this would affect the treatment’s development. After illustrating the weaknesses of such arguments, it will be concluded that MRT should be funded by the NHS. (shrink)

A common current refrain laments that multiculturalism has failed as a policy model and that it should be replaced by interculturalism. In this article, we present a critical analysis of the backgrounds and targets of multiculturalism and interculturalism. While multiculturalism concerns rights, equality and justice, interculturalism relates to social cohesion, shared participation and practices. Instead of merely juxtaposing these two paradigms, we illustrate the extent to which they are both different and complementary, as well as why they should be implemented (...) simultaneously. Intercultural and multicultural policies can be mutually reinforcing, in addition to adjusting or compensating for possible undesirable outcomes. By emphasising their complementarities, we go beyond the arguments of those who would expel multiculturalism in favour of interculturalism, as well as those who believe that multiculturalism already incorporates the merits of interculturalism. We also demonstrate the presence of both multicultural and intercultural aspects in the ‘civic integration’ policies that are being implemented with increasing rigour in several countries of immigration.

It seems to be a widespread opinion that increasing the length of existing happy lives is better than creating new happy lives although the total welfare is the same in both cases, and that it may be better even when the total welfare is lower in the outcome with extended lives. I shall discuss two interesting suggestions that seem to support this idea. Firstly, the idea there is a positive level of well-being above which a life has to reach to (...) have positive contributive value to a population. This view is usually called critical level utilitarianism. Secondly, the viewthat it makes an outcome worse if people are worse off than they otherwise could have been. I shall call this view comparativism. Firstly, I shall describe what I call the pure case of life extension versus replacement. Then I shall very briefly describe some different views about the value of life extension and indicate why I think some of the arguments in favor and against life extension fail. I shall then turn to the implications of critical level utilitarianism and comparativism in regards to life extension versus replacement, which is the main topic of this chapter. (shrink)

Epithelial stem cells have been identified in integumental structures such as hairs and continuously growing teeth of various rodents, and in the gut. Here we propose the involvement of epithelial stem cells in the continuous tooth replacement that characterizes non‐mammalian vertebrates, as exemplified by the zebrafish. Arguments are based on morphological observations of tooth renewal in the zebrafish and on the similarities between molecular control of hair and tooth formation. Dissection of the molecular cascades underlying the regulation of the epithelial (...) stem cell niche might open perspectives for new regenerative treatment strategies in clinical dentistry.

Should doctors have the possibility to save children from incurable suffering and end their lives?. At first glance, the standpoints in the debate around this question seem translucent and well known and the debate intelligible. I contend that this is not the case and I will illustrate this in analysing the debate between Peter Singer and Ulrich Bleidick. Whomever wants to answer the question whether it is acceptable to end the lives of suffering small children will have to do some (...) careful reading and thinking about the different and differing moral arguments in the debate. This demands emotional restraint and intellectual honesty. Trying to understand Singer and his opponents is a challenging way of charting what exactly is at stake in this debate. (shrink)

In recent times it has become common to encounter philosophers who recommend the replacement of one principle concerning theory choice, Ockham’s Razor, with another: the Laser. Whilst the Razor tells us not to multiply entities beyond necessity, the Laser tells us only to avoid multiplying fundamental entities beyond necessity. There appear to be seven arguments in the literature for the Laser. They divide into three categories: arguments from the nature of non-fundamentality attempt to motivate the Laser by appeal to various (...) observations about what it is to be non-fundamental; arguments from cases describe hypothetical or actual cases, and allege that only the Laser accords with our intuitive judgements about them; and arguments from analogy claim that ontological parsimony is analogous to conceptual economy, and that this analogy recommends the Laser. I provide novel responses to each of the extant arguments for the Laser, and conclude that there is currently no good reason for replacing the Razor with the Laser. (shrink)

Mitochondrial replacement techniques (MRTs) have made headlines as some countries have passed legislation permitting the creation of “three-parent embryos” and because of the recent revelation that a child has already been born following the use of these techniques. MRTs assist women with severe mitochondrial disease to have children who are free from mitochondrial disease. Essentially, the mitochondrial DNA of an ovum or embryo is removed and replaced with the mtDNA of a donor. The purpose of this paper is to argue (...) that MRTs are ethically impermissible but greater regulation is needed. There are five parts to this paper: (1) a brief history of mitochondrial manipulation, (2) a description of the MRT process, (3) ethical arguments in opposition to MRTs, (4) relevant counterarguments, and (5) a proposal for increased regulation.

Williams argued that Darwin replaced teleology by natural selection. This article argues that this idea is based on a misunderstanding of Darwin’s critique of the argument from design. Darwin did not replace teleology by evolutionary explanations but showed that we can understand teleology without referring to a Designer. He eliminated the concept of design and rehabilitated Aristotelian teleological explanations. The implication is that adaptations should not be investigated as if designed, but with the help of both teleological and evolutionary (...) explanations. It is argued that elaborations of teleological explanations enable us to reconcile evolutionary theory and other fields in science. (shrink)

This paper contains a novel and coherent reading of Weberian ideal type construction, based on recent philosophical approaches to conceptual engineering. This reading makes transparent the dialectics of Weber's approach, resulting in a more nuanced interpretation of his methodological work. It will become apparent that Weber, when introducing his notion of an ideal type, did not merely summarize his views on methodology in the social sciences, but, rather, presented a two-step argument in favor of these views. The reconstruction will (...) directly bear on issues in the methodology of the social sciences. Weber not only presented a methodology that is, at some level of abstraction, strikingly similar to Carnapian explication (the canonical point of reference in the contemporary debate on conceptual engineering). He also diagnosed, in a systematic fashion, types of problems we face when dealing with ordinary and scientific concepts that play a key role in the description of social reality, and he foreshadowed what is today sometimes described as “debunking” projects. From a philosophy of science perspective, I propose Weber's view (on the reconstruction proposed here) as a serious candidate for an adequate theory of concept replacement in the social sciences.

For Charles Mills, the "Racial Contract" is a set of meta-agreements between whites to categorize nonwhites as subpersons of inferior moral and legal status relative to whites. This "contract" gives whites the right to exploit non-whites and deny them opportunities provided to whites.

Florence Ashley has responded to our response to ‘Gatekeeping hormone replacement therapy for transgender patients is dehumanising.’ Ashley criticises some of our objections to their view that patients seeking hormone replacement therapy (HRT) for gender dysphoria should not have to undergo a prior psychological assessment. Here we clarify our objections, most importantly that concerning the parity between cosmetic surgery and the sort of intervention Ashley has in mind. Firstly, we show Ashley’s criticism of our comparison is insubstantial. We then examine (...) their comments regarding the analogy between abortion and HRT, and the language of informed consent. We also scrutinize the data upon which Ashley relies to defend the claim that informed consent without assessment always yields positive outcomes, finding this conclusion to be overstated. Finally, even if Ashley’s arguments were vindicated, the claim that the gatekeeping of HRT is motivated by hostility towards transgender people remains unsupported. (shrink)

This paper addresses two methodological paths in Artificial Intelligence: the paths of Babbage and anti-Cartesianism. While those researchers who have followed the latter have attempted to reverse the Cartesian dictum according to which machines cannot think in principle, Babbage’s path, which has been partially neglected, implies that the replacement of humans—and not the creation of minds—should provide the foundation of AI. In view of the examined paths, the claim that we support here is this: in line with Babbage, AI researchers (...) have recently concentrated upon the replacement of human labour, and thus upon the creation of Machine Learning systems. After presenting and analysing the paths, we characterise Machine Learning via its developments and an illustrative example. Then, we put forward an argument that shows that total replacement of human labour will not be feasible for practical and conceptual reasons despite the successful developments in recent AI systems. Our discussion finally leads to optimism and awareness: AI’s advances allow humans to dedicate themselves to higher level tasks, but these advances also require that we be vigilant about the responsibilities granted to ML-based systems.

In this article, an ethical analysis of an educational programme on renal replacement therapy options for patients and their social network is presented. The two main spearheads of this approach are: (1) offering an educational programme on all renal replacement therapy options ahead of treatment requirement and (2) a home-based approach involving the family and friends of the patient. Arguments are offered for the ethical justification of this approach by considering the viewpoint of the various stakeholders involved. Finally, reflecting on (...) these ethical considerations, essential conditions for carrying out such a programme are outlined. The goal is to develop an ethically justified and responsible educational programme. (shrink)

In this journal, Dr Daniel Daly, an American bioethicist, uses a principlist approach (respect for autonomy, non-maleficence, beneficence and justice) to argue that intravenous opiate users should not be denied repeat heart valve replacements if these are medically indicated, ‘unless the valve replacement significantly violates another’s autonomy or one or more of the three remaining principles’.1 In brief outline, the paper seeks to use a widely accepted ethical theory—‘principlism’ as developed by Beauchamp and Childress over the last 40 plus years (...) and eight editions of their ground-breaking book Principles of Biomedical Ethics2—to resolve clinical disagreement about the ethics of denying medically indicated life-prolonging treatment to patients who continue or resume intravenous opiate use. The argument Dr Daly's argument in very brief summary is that in the context of contemporary American medical practice, such treatment is ethically justified—perhaps even ethically required—if requested or accepted by an adequately autonomous patient and thus respects the patient’s autonomy, if it is not harmful to the patient, if it is beneficial to the patient, and if it is fair and just in terms of Aristotle’s formal theory of justice according to which equals should be treated equally while unequals should be treated unequally in proportion to the morally relevant inequality or inequalities. Dr Daly focuses his argument around a typical case description where these conditions are met and therefore where, he concludes, repeat heart valve replacements ought to be provided. As Dr Daly notes, principlism ‘is not without its problems; nonetheless it does provide a viable set of principles that are widely held by medical ethicists and inform the work of ethics committees at many secular medical facilities’.

New physiological and pharmacological research points to the possibility of a pill that produces the complete physiological effects of exercise. Is replacement of exercise with a pill a good idea? And if so, under what circumstances? To explore answers, I have examined three approaches to the understanding exercise. From a dualist point of view, exercise is explained mechanistically in terms of physiological cause and effect relationships. From this perspective, and in particular for reluctant exercisers, there seems to be no strong (...) argument against the use of a pill. From a phenomenological point of view, exercise is understood from a first person perspective focusing on experiential qualities. It is argued that a pill can never replace the embodied, experiential values of exercising and their potential ethical significance. In other words, the use of a pill is rejected. From a critical social constructivist point of view, exercise is understood as an expression of sociocultural values. Exercise can be a source of both bodily alienation and embodied self-realization and meaning. It is argued that in settings of alienating exercise malpractice, an exercise pill can be a temporary lesser evil approach. It is pointed out, however, that the long-term solution to malpractice is not a pill but a change of practice. In a final section, the possibility of the exercise pill is contextualized in the larger, bio-ethical debate on human enhancement. (shrink)

This essay considers Brian Leiter’s arguments for ‘replacement naturalism’ in the domain of adjudication, his thesis being that we should reject as plausible the ‘normative theory of adjudication’ and replace it witha posterioritheory which best explains the causes of judicial decisions.

Both Leiter’s original arguments for the position and (...) his more recent suggestions in response to critics are considered. (shrink)

If a state with liberal political and justificatory commitments extends benefits of various kinds to persons forming families, what qualifications may such a state place on the right to access to those benefits? I will make two assumptions for the purposes of this paper. The first is the political and justificatory terrain of some form of political or otherwise non-perfectionist liberalism. The assumption is that we are considering the resources and limitations of a community of persons who accept moral pluralism (...) (if not a specific doctrine like the "burdens of judgment"), some priority for individual freedom, and the obligation to justify public coercion and exclusion in terms accessible and fair to all members of morally and culturally diverse society. The second is that it is justified for a liberal state to recognize some forms of domestic partnerships or families in the first place and extend further benefits to them such as tax credits or laws extending (or facilitating the extension of) medical or social insurance. It is, of course, possible to imagine the argument that the liberal state gets out of the marriage business by getting out of it entirely - by extending no recognition or positive rights to families whatsoever beyond negative non-interference rights. I am interested in the dilemma of a society broadly like existing liberal ones which is committed both to subsidizing families and also to justificatory neutrality (expressed in American constitutional legal terms as the requirement of providing a "rational basis" for unequal treatment). Given these assumptions, I believe that the most justifiable policy on liberal grounds is not the institution of "marriage" increasingly open to new constituent relationships but rather a status of "registered domestic partnership" which fulfills the social and moral aims behind subsidizing the family but is entirely neutral not only to the gender or even to the numbers of the partners, but also to the affective and emotional content of domestic life and the purposes behind contracting domestic partnerships. So is there a right to polygamy and incestuous marriage? There is not a specific right to either and thus there is no a priori reason why some restrictions or even prohibitions on them might not be justified, but the same is true for every specific act where a general right to the freedom exists. I argue in this paper, however, that the arguments compatible with public reason for prohibiting them outright, or even for excluding them from the permissible types of legally registered partnerships, are quite weak. I argue that objections to polygamy from (1) female autonomy, (2) damage to children, (3) fairness in the marital market, and (4) the unfair burdening of society are serious and worth refuting, but do not establish a victorious case against multi-member relationships. As to incest, there are two separate questions. The first is whether the new institution of "registered domestic partnerships" should be open to them. The answer to that, given the state's lack of interest in citizens' reasons for forming partnerships and in what they do whilst being registered in one, is clearly "yes." The second is whether, entirely separate from the issue of legal recognition of domestic partnership, the state has a legitimate rational interest in deterring, preventing or punishing consanguineous sexual relations between close blood relations (first-degree incest). Here, the objections to allowing such relations are those from (1) child abuse; (2) unfair burdening of society; and (3) the creation of bad lives. I argue that while rape and other forms of child abuse would be no more legal or tolerated than they are now, the concern about any form of weakening a society's legal and political resources to combat such abuses does indeed register on the justificatory scale, but does not prove that such first-degree incestuous sexual relations are inherently bad enough to warrant intervention. I then argue that the concern about unfairly burdening society with unhealthy persons is not as dangerously totalitarian as we might initially fear, but nor is it strong enough to justify an outright prohibition. Finally, I argue that a concern to dissuade persons from creating certain kinds of lives (children with extreme birth defects) is also not as dangerously totalitarian as we might initially fear, and in fact goes further towards explaining why we might have a legitimate interest in intervening. Nonetheless, I argue that the criminalization of such acts only make sense when they are indicators of other offenses, namely negligence or abuse, and it thus seems that the act of consanguineous reproduction is itself insufficient.

The aim of this book is to show how McTaggart's atemporal vision of reality is a serious attempt to describe a coherent world without time. It proposes that the answer to the puzzling nature of time is not to be found in the components of time itself, but in an atemporal reality that lies behind it. McTaggart takes an idealist view that reduces all that is real to spirit, that any expression of reality is dependent on a manifestation of consciousness. (...) McTaggart's argument that time is unreal, has been the subject of much philosophical debate since it first appeared in 1908; but much discussion has ignored McTaggart's positive account of time and concentrated on his negative proof. The author argues that the negative thesis should be separated from the positive account, he attacks the standard approaches to interpreting time and provides a full account of McTaggart's atemporal world. The conclusion is drawn that the timeless world has psychological appeal and can form the basis for an atemporal thinking which can break away from the confusing philosophical models of temporality that often bear little resemblance to our experience of it.

[From Euthanasia to Infanticide] The paper revisits the recent controversy over Dr. Mitlőhner’s defense of infanticide, published in this journal. In section 1, I point out the weaknesses of Mitlőhner’s paper. In sections 2 and 3 I turn to the most sophisticated defense of infanticide on offer today, that of Peter Singer’s. Section 2 sums up Singer’s description of the medical practice as already having abandoned the traditional ethic of equal value of all human lives, which motivates ethical revisionism. However, (...) an explicit justification of a revision is necessary. This is the job of Singer’s Replacement Argument, examined in section 3. I argue that this justification of infanticide in completely impersonal terms fails. In section 4, I reject it in favor of Ronald Dworkin’s distinction between experiential interests, possessed by infants, and critical interests that develop later. Hence, neonatal euthanasia can sometimes be justified in terms of a newborn‘s own interests (presumably, to relieve its suffering), not in impersonal terms. The only exception is those infants that lack any capacity for cognitive activity whatsoever, and who thus lack even experiential interests. It is an open question whether their “life” differs from death, and whether by killing them we perform infanticide. (shrink)

I propose some arguments suggested by Descartes' text for the conclusion that we are not identical to our bodies. I suggest that a natural extension of those arguments leads to Plantinga's Replacement Argument. I conclude that even if such an argument is plausible, its conclusion does not establish the further claim that we can exist without a body.

In the third edition of ‘Practical Ethics’ (2011), Peter Singer reexamines the so-called “replaceability argument,” according to which merely sentient beings, as opposed to persons (self-conscious and with a robust sense of time), are replaceable—it is in principle permissible to kill them provided that they live pleasant lives that they would not have had otherwise and that they be replaced by equally happy beings. On this view, existence is a benefit and death is not a harm. Singer’s challenge (...) is to avoid (i) the replaceability of persons while preserving the replaceability of merely sentient beings, (ii) the implication that parents are morally required to procreate if they can have happy children, and (iii) to do avoid these implications without having the proposed solution (the “debit view” of preferences) imply negative utilitarianism, or the conclusion that a nonsentient universe is better than any sentient universe. I review Singer’s changing views since 1975 and I argue that his attempt to avoid the replaceability of persons fails: either both non-persons and persons are replaceable or neither are. Singer can only avoid this conclusion by appealing to controversial metaethical claims (attitude-independent moral objectivism) and/or giving up on essential features of utilitarianism. (shrink)

According to the indispensability argument, the fact that we quantify over numbers, sets and functions in our best scientific theories gives us reason for believing that such objects exist. I examine a strategy to dispense with such quantification by simply replacing any given platonistic theory by the set of sentences in the nominalist vocabulary it logically entails. I argue that, as a strategy, this response fails: for there is no guarantee that the nominalist world that go beyond the set (...) of sentences in the nominalist language such theories entail. However, I argue that what such theories show is that mathematics can enable us to express possibilities about the concrete world that may not be expressible in nominalistically acceptable language. While I grant that this may make quantification over abstracta indispensable, I deny that such indispensability is a reason for accepting them into our ontology. I urge that the nominalist should be allowed to quantify over abstracta whilst denying their existence and I explain how this apparently contradictory practice (a practice I call 'weaseling') is in fact coherent, unproblematic and rational. Finally, I examine the view that platonistic theories are simpler or more attractive than their nominalistic reformulations, and thus that abstract ought to be accepted into our ontology for the same sorts of reasons as other theoretical objects. I argue that, at least in the case of numbers, functions and sets, such arguments misunderstand the kind of simplicity and attractiveness we seek. (shrink)

Perry Hendricks’ impairment argument for the immorality of abortion is based on two premises: first, impairing a fetus with fetal alcohol syndrome is immoral, and second, if impairing an organism to some degree is immoral, then ceteris paribus, impairing it to a higher degree is also immoral. He calls this the impairment principle. Since abortion impairs a fetus to a higher degree than FAS, it follows from these two premises that abortion is immoral. Critics have focussed on the ceteris (...) paribus clause of TIP, which requires that the relevant details surrounding each impairment be sufficiently similar. In this article, we show that the ceteris paribus clause is superfluous, and by replacing it with a more restrictive condition, the impairment argument is considerably strengthened. There are no data in this work. (shrink)

What I hope to show here is that the costs of taking sorites arguments seriously, in particular the costs with respect to hopes for precise replacement are significantly greater than proponents of sorites arguments have estimated.

Without a proper restriction on mappings, virtually any system could be seen as implementing any computation. That would not allow characterization of systems in terms of implemented computations and is not compatible with a computationalist philosophy of mind. Information-based criteria for independence of substates within structured states are proposed as a solution. Objections to the use of requirements for transitions in counterfactual states are addressed, in part using the partial-brain argument as a general counterargument to neural replacement arguments.

Problems for 'precise replacements' as a way out of sorites paradoxes.
