The animal liberation movement, among other goals, seeks an end to the use of animals for food. The philosophers who started the movement agree on the goal but differ in their approach: deontologists argue that rearing animals for food infringes animals’ inherent right to life. Utilitarians claim that ending the use of animals for food will result in the maximization of utility. Virtue-oriented theorists argue that using animals for food is callus, self-indulgent, and unjust, in short, it’s an unvirtuous practice. (...) Despite their different approaches, arguments for vegetarianism or veganism have a common step. They move from the notion of suffering to the conclusion of vegetarianism or veganism. In this paper I suggest that the notion of animal suffering is not necessary in order to condemn the practice of animal farming. I propose the possibility of defending vegetarianism or veganism on the basis of arguments that do not rest on the notion of animal suffering, but rather rely on aesthetic principles, the avoidance of violence, and preservation of the environment, and health.

An influential argument in bioethics involves appeal to disgust, calling on us to take it seriously as a moral guide (e.g. Kass, Miller, Kahan). Some argue, for example, that genetic enhancement, especially via human reproductive cloning, is repellant or grotesque. While objectors have argued that repugnance is morally irrelevant (e.g. Nussbaum, Kelly), I argue that the problem is more fundamental: it is psychologically irrelevant. Examining recent empirical data suggests that disgust’s influence on moral judgment may be like fatigue: an exogenous (...) influence, yielding a “performance error” that does not reflect our understanding of moral matters. This conclusion also challenges appeals to repugnance on other topics (such as homosexuality) and generally downplays the importance of disgust in moral discourse. (shrink)

By many accounts, CRISPR gene-editing technology is revolutionizing biotechnology. It has been hailed as a scientific game changer and is being adopted at a break-neck pace. This hasty adoption has left little time for ethical reflection, and so this paper aims to begin filling that gap by exploring whether CRISPR is as much an ethical game changer as it is a biological one. By focusing on the application of CRISPR to non-human animals, I argue that CRISPR has and will continue (...) to result in significant shifts in the ethical debate landscape. For instance, the fact that many CRISPR edits are non-transgenic has important implications for the ethical debate, particularly the popular objection to genetic engineering that it objectionably involves “crossing species boundaries,” as well as the regulatory debate in the United States, where currently only transgenic organisms are officially genetically modified organisms. I also explore various impacts CRISPR may have on animal welfare, suggesting that although the improved precision of CRISPR suggests fewer unintended welfare problems in comparison to past techniques, the greater versatility means that more animals than ever will be engineered. Finally, I end my discussion of animal welfare issues by exploring the possibility of using CRISPR to directly improve animal welfare, for instance through introducing disease resistance. (shrink)

The rhetoric of disgust is common in moral discourse and political propaganda. Some believe it's pernicious, for it convinces without evidence. But scientific research now suggests that disgust is typically an effect, not a cause, of moral judgment. At best the emotion on its own only sometimes slightly amplifies a moral belief one already has. Appeals to disgust are thus dialectically unhelpful in discourse that seeks to convince. When opponents of abortion use repulsive images to make their case, they convince (...) few, even if they rally their base. When champions of animal rights show graphic depictions of the torturous conditions of animals in factory farms, they convince only those previously ignorant of the severity of such conditions. Ultimately, disgust may be less pernicious than it is useless. (shrink)

Gary Comstock considers whether it is ethically justified to pursue genetically modified (GM) crops and foods. He first considers intrinsic objections to GM crops that allege that the process of making GMOs is objectionable in itself. He argues that there is no justifiable basis for the objections — i.e. GM crops are not intrinsically ethically problematic. He then considers extrinsic objections to GM crops, including objections based on the precautionary principle, which focus on the potential harms that may result from (...) the adoption of GM organisms. He argues that these concerns have some merit. However, they do not justify giving up GM crops altogether. Instead, they require that GM crops be developed carefully and with appropriate oversight. Comstock then presents the positive case for GM crops that he endorses. It is based on three considerations: (i) the right of people to choose to adopt GM technology; (ii) the balance of likely benefits over harms to consumers and the environment from GM technology; and (iii) the wisdom of encouraging discovery, innovation, and careful regulation of GM technology.

The philosophical debate over disgust and its role in moral discourse has focused on disgust’s epistemic status: can disgust justify judgments of moral wrongness? Or is it misplaced in the moral domain—irrelevant at best, positively distorting at worst? Correspondingly, empirical research into disgust has focused on its role as a cause or amplifier of moral judgment, seeking to establish how and when disgust either causes us to morally condemn actions, or strengthens our pre-existing tendencies to condemn certain actions. Both of (...) these approaches to disgust are based on a set of assumptions that I call, in what follows, the evidential model of disgust. This paper proposes an alternative model, which I call the response model. Instead of looking at disgust as a cause and justification of judgments of moral wrongness, I will argue that disgust is better understood as a response to wrongness. More precisely, I argue that disgust is a response to norm violations, and that it is a fitting response insofar as norm violations are potentially contagious and therefore pose a threat to the stability and maintenance of norms.

In 2011, Ingmar Riedel‐Kruse's bioengineering laboratory at Stanford University publicized an application that uses paramecia for what the researchers termed “biotic games.” These games make use of living organisms, computer programs, and lab equipment to implement games like Pong, Pac‐man, and soccer. Gamesand related activities are often considered nonserious or trivial, whereas life, biological systems, and science are treated very seriously in moral analysis and public perception. The manipulation of living matter frequently engenders at least some controversy in the marketplace (...) of ideas, and using living things in games is no exception. Some of the objections lodged against biotic games have appeared in the ethics literature on similar topics; however, the addition of an entertainment element introduces some objections distinct from those about similar cases, as the online comments vividly illustrate. We aim to explore and address the objections in this paper, using the comments to organize and launch the discussion. In scientific work, there is typically a presumption of some prospect of translation and application of generated knowledge for public benefit. In the case of biotic games, these applications are not self‐evident. Because of this, a serious analysis of the justifications, limitations, and features of biotic games is warranted. To this end, we outline key ethical limits that ought to be placed on these activities as well as the obligations that these activities generate for researchers, other professionals, and lay people who design, implement, use, and play them.

Bernard Rollin argues that it is permissible to change an animal's telos through genetic engineering, if it doesn't harm the animal's welfare. Recent attempts to undermine his argument rely either on the claim that diminishing certain capacities always harms an animal's welfare or on the claim that it always violates an animal's integrity. I argue that these fail. However, respect for animal dignity provides a defeasible reason not to engineer an animal in a way that inhibits the development of those (...) functions that a member of its species can normally perform, even if the modification would improve the animal's welfare.

The view we defend is that in virtue of its nature, disgust is not fit to do any moral or social work whatsoever, and that there are no defensible uses for disgust in legal or political institutions. We first describe our favoured empirical theory of the nature of disgust. Turning from descriptive to normative issues, we address the best arguments in favour of granting disgust the power to justify certain judgements, and to serve as a social tool, respectively. Daniel Kahan (...) advances a pair of theses that suggest disgust is indispensable (Moral Indispensability Thesis), and so has an important part to play in the functioning of a just, well-ordered society (Conservation Thesis). We develop responses and show how they rebut the arguments given in support of each thesis. We conclude that any society free of social disgust would be more just, reasonable and compassionate.

This paper presents a way of classifying different forms of naturalness and unnaturalness. Three main forms of (un)naturalness are found as the following: history- based (un)naturalness, property-based (un)naturalness and relation-based (un)naturalness. Numerous subforms (and some subforms of the subforms) of each are presented. The subforms differ with respect to the entities that are found (un)natural, with respect to their all-inclusiveness, and whether (un)naturalness is seen as all-or-nothing affair, or a continuous gradient. This kind of conceptual analysis is needed, first, because (...) discussion concerning (un)naturalness is common in current bioethics and environmental ethics, and second, because the terms natural and unnatural are highly ambiguous. Thus, the lack of an exact definition of the type of (un)naturalness may lead into equivocation, other forms of bad argumentation, or at least vagueness. (shrink)

In public debate GMPs are oftenreferred to as being unnatural or a violationof nature. Some people have serious moralconcerns about departures from what is natural.Others are concerned about potential risks tothe environment arising from the combination ofhereditary material moving across naturalboundaries and the limits of scientificforesight of long-term consequences. To addresssome of these concerns we propose that anadditional element in risk assessment based onthe concept of familiarity should beintroduced. The objective is to facilitatetransparency about uncertainties inherent inthe risk assessment of (...) the GMP. Familiarityconventionally involves data and experiencerelating to the plant species and the ecosystemin question. We would like to extend thisconcept to the molecular level of plantbreeding and suggest that GMP characteristicsshould be compared to a reference baselinedetermined by conventional breeding techniques.Three GMPs are ranked according to familiarityat the plant and ecosystem level and themolecular level. The approach may help tointegrate discussion of the scientificarguments and moral questions raised in thedebate about GMOs by providing an operationalscheme within which moral concerns are broughtwithin the framework of science-based riskassessment.

The term moral considerability refers to the question of whether a being or set of beings is worthy of moral consideration. Moral considerability is most readily afforded to those beings that demonstrate the clearest relationship to rational humans, though many have also argued for and against the moral considerability of species, ecosystems, and “lesser” animals. Among these arguments there are at least two positions: “environmentalist” positions that tend to emphasize the systemic relations between species, and “liberationist” positions that tend to (...) emphasize the attributes or welfare of a particular individual organism. Already, this classic conflict provides for some challenging theoretical clashes between environmentalists and animal liberationists. The question of moral considerability is complicated, however, by recent developments in genetic engineering. Some animals, like pigs and fish, have been genetically modified by humans to grow organs that can then be transplanted into humans. If environmental arguments for the moral consideration of species are correct, then we are released from our obligations to morally consider those animals that we have genetically modified, since they are by their nature always an “invader species.” If, instead, the welfare of the animal is of penultimate importance, then there is a case for strengthening the moral considerability of GM animals over “naturally-occurring” animals, since they bear a closer relationship to humans. This would appear to be an intractable problem, a “bad marriage,” as Mark Sagoff once proposed. This paper argues that the case of invasive transgenic animals exposes weaknesses in this classic conflict, and particularly, in the framing of this conflict. To remedy this framing problem, this paper argues for a reconceptualization of the term “moral considerability,” instead urging a strong distinction between moral considerability, moral relevance, and moral significance.

Martha Nussbaum argues that animals are entitled to a flourishing life according to the norm for their species. Nussbaum furthermore suggests that in the case of dogs, breed norms as well as species norms are relevant. Her theses capture both common intuitions among laypeople according to which there is something wrong with the breeding of “unnatural” animals, or animals that are too different from their wild ancestors, and the dog enthusiast’s belief that dogs departing from the norms for their breed (...) are tragic. I argue that the high diversity of the dog species and the ultimate arbitrariness of breed norms support the thesis that a conception of welfare must be tied to what the individual requires in order to flourish. In the second part of the paper, I discuss the implications that an individualized welfare conception has for the breeding of dogs for conformation shows, for the pet market and for the performance of various tasks for which we need working dogs.

This study is a contribution to the bioethical debate about new and possibly emerging reproductive technologies. Its point of departure is the intuition, which many people seem to share, that using such technologies to select non-disease traits – like sex and emotional stability - in yet unborn children is morally problematic, at least more so than using the technologies to avoid giving birth to children with severe genetic diseases, or attempting to shape the non-disease traits of already existing children by (...) environmental means, like education. The study employs philosophical analysis for the purpose of making this intuition intelligible and judging whether it is justified. Different ways in which the moral problems posed by reproductive technologies are often framed in bioethical debates are criticised as inadequate for this task. In particular, it is argued that the intuition cannot fully be made sense of in terms of harm to the children that such technologies help create. The study attempts to elaborate an alternative to that broadly consequentialist approach, by drawing on Martin Heidegger’s philosophy of technology, Hans Jonas’s ethics, and Aristotle’s practical philosophy, as it has been received and developed in the hermeneutical tradition. It is suggested that reproductive choices, unlike decisions for already born children, are characterised by a peculiar one-sidedness: the future child appears to the parents as something wholly theirs to decide about, not as a concrete other with whom they must interact in a responsive and attuned way. This is problematic because it means that such choices cannot call upon the particularised moral understanding only gained in interpersonal encounters. In particular, it makes them easily shaped by various tendencies, to which parents are always susceptible, to relate to children in instrumentalising ways, and at risk of reinforcing such tendencies. However, this does not mean that all uses of reproductive technologies are equally troubling. When selecting against severe disease the parents can rely on a widely shared illness experience to escape the dangers that one-sidedness involves. It is concluded that the intuition under discussion, thus explicated and in some ways qualified, makes sense morally. (shrink)

Articulating the public's widespread unease about animal biotechnology has not been easy, and the first attempts have not been able to provide an effective tool for navigating the moral permissibility of this research. Because these moral intuitions have been difficult to cash out, they have been belittled as representing nothing more than fear or confusion. But there are sound philosophical reasons supporting the public's opposition to animal biotechnology and these arguments justify a default position of resistance I call the Presumption (...) of Restraint . The Presumption of Restraint constitutes a justificatory process that sets out the criteria for permitting or rejecting individual biotechnology projects. This Presumption of Restraint can be overridden by compelling arguments that speak to a project's moral and scientific merit. This strategy creates a middle-of-the-road stance that can embrace particular projects, while rejecting others. The Presumption of Restraint can also serve as a model for assessing moral permissibility in other areas of technological innovation. (shrink)

What types of human-animal interspecific entities are used in biomedical research? Is creating such entities morally wrong? And what do interspecifics tell us about the moral significance of species? This thesis offers an introduction to the field of human-animal interspecifics from a bioethical perspective, with a special focus on the question of speciesism.

This paper explores one aspect of the social implications of new reproductive technologies, namely, the impact such technologies have on our understandings of family structures and our expectations of children. In particular it considers whether the possibilities afforded by such technologies result in a more contractual and commodified understanding of children. To do this the paper outlines the possibilities afforded by NRTs and their commodificatory tendencies; second, it explores the commodification debate using the somewhat parallel example of commodification of organs; (...) and third, in light of these debates the link between the commodification of body parts and persons is addressed. It will argue that there is a prime facie connection between body parts and persons and thus, although needing to be balanced with other ethically relevant factors, commodification remains an issue of ethical concern. Accordingly we should only be supporting potentially commodifying practices when there are ethically pressing reasons to do so (such as in organ transplantation). Moreover given this link between body part and persons we should attempt to lessen commodifying attitudes and thus should resist the increasing use of practices which regard children as having choose-able parts.

One of the reasons why GMOs have met public resistance in the past is that they are perceived as “unnatural”. The basis for this claim has, in part, to do with crossing species boundaries, which is considered morally objectionable. The emergence of CRISPR is sometimes argued to be an ethical game-changer in this regard since it does not require the insertion of foreign genes. Based on an empirical bioethics study including individual interviews and focus groups with laypeople and other stakeholders, (...) this article analyses the normative role of appeals to naturalness in discussions about the moral acceptability of using CRISPR in salmon farming. It discusses two dimensions of naturalness found in the material– living by species-specific nature and being unaffected by humans– and argues that these dimensions put down criteria for the application of CRISPR that lead to a conflict between our moral duties towards the farmed salmon and those we hold towards the wild salmon as a threatened species. It also points to a paradox which is likely to gain traction with further climate change and biodiversity loss, namely that while nature, understood as that which is unaffected by humans, is presented as an ideal, conserving nature in its pristine state may rely on technology and human intervention.

Nanotechnologies that have been linked to the possibility of enhancing cognitive capabilities of human beings might also be deployed to reduce or eliminate such capabilities in non-human vertebrate animals. A surprisingly large literature on the ethics of such disenhancement has been developed in response to the suggestion that it would be an ethically defensible response to animal suffering both in medical experimentation and in industrial livestock production. However, review of this literature illustrates the difficulty of formulating a coherent ethical debate. (...) Well structured arguments for disenhancement can be made on the basis of mainstream views on the basis of ethical obligations to animals, but these arguments have not been persuasive against the moral intuition that disenhancements are unethical. At the same time, attempts to ground these intuitions in a coherent philosophical doctrine have been plagued by logical fallacies and question begging assertions. As such, the debate over animal disenhancement forecasts an enduring conundrum with respect to the core question of transforming the nature of sentient beings, and this conundrum is logically independent of claims that relate either to the distinctive of human beings or to issues deriving from the emphasis on enhancement.

Should face transplants be undertaken? This article examines the ethical problems involved from the perspective of the recipient, looking particularly at the question of identity, the donor and the donor’s family, and the disfigured community and society more generally. Concern is expressed that full face transplants are going ahead.

The goal of responsible engineers is the creation of useful and safe technological products and commitment to public health, while respecting the autonomy of the clients and the public. Because engineers often face moral dilemma to resolve such issues, different engineers have chosen different course of actions depending on their respective moral value orientations. Islam provides a value-based mechanism rooted in the Maqasid al-Shari‘ah (the objectives of Islamic law). This mechanism prioritizes some values over others and could help resolve the (...) moral dilemmas faced in engineering. This paper introduces the Islamic interpretive-evaluative maxims to two core issues in engineering ethics: genetically modified foods and whistleblowing. The study aims primarily to provide problem-solving maxims within the Maqasid al-Shari‘ah matrix through which such moral dilemmas in science and engineering could be studied and resolved. (shrink)

Labioplasty is a surgical procedure performed to alter the size and shape of the labia minora. The reasons for women requesting this procedure remain largely unknown and recently girls and young women under the age of 18 years have been requesting this type of surgery. This paper examines the ethical acceptability of performing this procedure on under 18s. We will first discuss whether labioplasty can be considered to be a therapeutic technique. We will claim that, while it is difficult to (...) offer a definitive definition of what constitutes a therapeutic technique, in our view labioplasty cannot be considered as such. This conclusion has relevance for the ethical acceptability of the procedure, its legal status in regard to the Female Genital Mutilation Act and the debates over who can give consent for it. It will be concluded that in our current state of knowledge, the benefits of labioplasty are far from clear, whereas the harms are demonstrable and therefore this procedure should not be offered to those aged under 18 years.

To inform the ongoing discussion of whether claims of conscientious objection allow medical professionals to refuse to perform tasks that would otherwise be their duty, this paper begins with a review of the philosophical literature that describes conscience as either a moral sense or the dictate of reason. Even though authors have starkly different views on what conscience is, advocates of both approaches agree that conscience should be obeyed and that keeping promises is a conscience-given moral imperative. The paper then (...) considers exemplars of conscientious objection—Henry David Thoreau, Mohandas Gandhi, and Martin Luther King Jr.—to identify the critical feature of conscientious objection as willingness to bear the burdens of one’s convictions. It concludes by showing that medical professionals who put their own interests before their patients’ welfare violate their previous commitments and misappropriate the title “conscientious objector” because they are unwilling to bear the burdens of their choices and instead impose burdens on their patients and colleagues.

Das Cognitive Enhancement, die Steigerung der geistigen Leistungsfähigkeit gesunder Menschen durch Psychopharmaka und andere Interventionen, ist in jüngster Zeit verstärkt in den Fokus sowohl der Ethik als auch der breiteren Öffentlichkeit geraten. In kontrafaktischer Abstrahierung vom gegenwärtig noch sehr bescheidenen Stand der Technik wird dabei unter anderem erörtert, was grundsätzlich für und was gegen den Einsatz von markant wirksamem Cognitive Enhancement sprechen würde.

Ein besonderes Augenmerk wird auf die Frage gelegt, was für einen Einfluss der Einsatz von Cognitive Enhancement auf unser Menschenbild und auf andere Teile des epistemischen Fundaments unserer Kultur haben könnte.

Ongoing research on making “human-animal chimeras” or “animals containing human material” to solve the shortage of organs available for transplantation has raised many ethical issues regarding the creation and utilization of such constructs, including cultural views regarding the status of those creations. A pilot study was conducted to explore Japanese public attitudes toward human-animal chimeras or ACHM. The February 2012 study consisted of focus group interviews with citizens from the Greater Tokyo Area, aged between 20 and 54. The 24 participants (...) were divided into four groups. Transcripts of the interviews were analyzed and participants’ attitudes categorized. Five categories of participant attitudes were identified: resistance to the unnatural, concerns about animal welfare, concerns about controlling human-animal chimeras, concerns about the possible birth of intermediate entities, and resistance to creating and utilizing animals containing my material or my child’s material. Our FGI results showed a broader and greater variety of public concerns than those reported in previous studies. While researchers have tried to establish new methods to avoid creating intermediate entities, our participants expressed concerns about not only intermediate entities but also animals containing their own material or their child’s material. Based upon their responses in the interviews, we are introducing a new ethical concern: “animals containing my material/my child’s material.”. (shrink)

The extent to which society utilises the law to enforce its moral judgments remains a dominant issue in this era of embryonic stem cell research, preimplantation genetic diagnosis, and human reproductive cloning. Balancing the potential health benefits and diverse moral values of society can be a tremendous challenge. In this context, governments often adopt legislative bans and prohibitions and rely on the inflexible and often inappropriate tool of criminal law. Legal prohibitions in the field of reproductive genetics are not likely (...) to reflect adequately the depth and diversity of competing stakeholder positions. Rather, a comprehensive and readily responsive regulatory policy is required. Such a policy must attend to the evolving scientific developments and ethical considerations. We outline a proposal for effective, responsive, and coherent oversight of new reproductive genetic technologies. (shrink)

Participants in the long-running bioethical debate over human germline genetic modification (HGGM) tend to imagine future people abstractly and on the basis of conventionalized characteristics familiar from science fiction, such as intelligence, disease resistance and height. In order to distinguish these from scientifically meaningful terms like “phenotype” and “trait,” this article proposes the term “persemes” to describe the units of difference for hypothetical people. In the HGGM debate, persemes are frequently conceptualized as similar, modular entities, like building blocks to be (...) assembled into genetically modified people. They are discussed as though they each would be chosen individually without affecting other persemes and as though they existed as components within future people rather than being imposed through social context. This modular conceptual framework appears to influence bioethical approaches to HGGM by reinforcing the idea of human capacities as natural primary goods subject to distributive justice and supporting the use of objective list theories of well-being. As a result, assumptions of modularity may limit the ability of stakeholders with other perspectives to present them in the HGGM debate. This article examines the historical trends behind the modular framework for genetically modified people, its likely psychological basis, and its philosophical ramifications. (shrink)

Transformative technologies can radically alter human lives making us stronger, faster, more resistant to disease and so on. These include enhancement technologies as well as cloning and stem cell research. Such technologies are often approved of by many liberals who see them as offering us opportunities to lead better lives, but are often disapproved of by conservatives who worry about the many consequences of allowing these to be used. In this paper, we consider how a democratic government with mainly liberal (...) values that is governing a population divided between liberals and conservatives can introduce new transformative technologies and try to achieve consensus about the introduction of such technologies. To do so, we draw on recent work in moral psychology which enables us to better understand the intuitive and emotional responses that underpin conservative objections to such new technologies. We then show how a government may introduce incremental changes in our social practices that have the long-term effect of weakening conservative objections to transformative technologies and better enabling governments to achieve consensus about these.
