De-domestication is the deliberate establishment of a population of domesticated animals or plants in the wild. In time, the population should be able to reproduce, becoming self-sustainable and incorporating 'wild' animals. Often de-domestication is part of a larger nature restoration scheme, aimed at creating landscapes anew, or re-creating former habitats . De-domestication is taken up in this paper because it both engages and raises questions about the major norms governing animals and nature. The debate here concerns whether animals undergoing de-domestication (...) should be looked upon as wild or non-wild and the effect this has on questions about how they should be treated. It also concerns the value of nature, and the kind and degree of nature management considered appropriate. The paper first describes actual de-domestication practices and considers the character of human duties to animals in process of de-domestication. Secondly, the paper explores the implications of de-domestication for nature management, focusing on notions of naturalness and wildness. Finally, because the current division of ethical topics, with its dependence upon whether animals and nature are domesticated, hampers rather than helps, a new perspective is offered on the issues raised by de-domestication. More 'thinking outside the box' with regard to animals and nature is recommended. (shrink)

The use of multiple means of determination to “triangulate” on the existence and character of a common phenomenon, object, or result has had a long tradition in science but has seldom been a matter of primary focus. As with many traditions, it is traceable to Aristotle, who valued having multiple explanations of a phenomenon, and it may also be involved in his distinction between special objects of sense and common sensibles. It is implicit though not emphasized in the distinction between (...) primary and secondary qualities from Galileo onward. It is arguably one of several conceptions involved in Whewell’s method of the “consilience of inductions” (Laudan 1971) and is to be found in several places in Peirce. (From M. Brewer and B. Collins, eds., (1981); Scientific Inquiry in the Social Sciences (a festschrift for Donald T. Campbell), San Francisco: Jossey-Bass, pp. 123–162.). (shrink)

Winner of the 1975 National Book Award, this brilliant and widely acclaimed book is a powerful philosophical challenge to the most widely held political and social positions of our age--liberal, socialist, and conservative.

More than twenty years after its original publication, The Case for Animal Rights is an acknowledged classic of moral philosophy, and its author is recognized as the intellectual leader of the animal rights movement. In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

This chapter discusses the application of the capabilities approach to the question of animal rights. It explains that this approach provides better theoretical guidance on the issue of animal entitlements over contractarian and utilitarian approaches because it is capable of recognising a wide range of types of animal dignity and of corresponding needs for flourishing. The chapter criticises the view of philosopher Immanuel Kant and his followers that mistreatment of animals does not raise questions of justice and suggests that the (...) claims of animals should be rooted in an understanding of what sorts of capabilities animals have.

When scientists seek further confirmation of their results, they often attempt to duplicate the results using diverse means. To the extent that they are successful in doing so, their results are said to be robust. This paper investigates the logic of such "robustness analysis" [RA]. The most important and challenging question an account of RA can answer is what sense of evidential diversity is involved in RAs. I argue that prevailing formal explications of such diversity are unsatisfactory. I propose a (...) unified, explanatory account of diversity in RAs. The resulting account is, I argue, truer to actual cases of RA in science; moreover, this account affords us a helpful, new foothold on the logic undergirding RAs. (shrink)

It is commonly asserted that “death is not a welfare issue” and this has been reflected in welfare legislation and policy in many countries. However, this creates a conflict for many who consider animal welfare to be an appropriate basis for decision-making in animal ethics but also consider that an animal’s death is ethically significant. To reconcile these viewpoints, this paper attempts to formulate an account of death as a welfare issue. Welfare issues are issues that refer to evaluations concerning (...) an animal’s interests. This includes evaluations that refer only to comparisons between the presence and absence of states, including positive states. This means that an animal’s death may be a welfare issue insofar as it leads to the exclusion of relevant positive states. This allows us to deny that death is necessarily not a welfare issue.

Entrenched biases in favour of large, charismatic mammals, towards predators, towards terrestrial animals and towards species that have cultural importance can influence the selection of candidate species for de-extinction research. Often, the species with the highest existence value will also be the ones that raise the most serious animal welfare concerns.

Since its original publication in 1975, this groundbreaking work has awakened millions of concerned men and women to the shocking abuse of animals everywhere--inspiring a worldwide movement to eliminate much of the cruel and unnecessary laboratory animal experimentation of years past. In this newly revised and expanded edition, author Peter Singer exposes the chilling realities of today's "factory farms" and product-testing procedures--offering sound, humane solutions to what has become a profound environmental and social as well as moral issue. An important (...) and persuasive appeal to conscience, fairness, decency and justice, Animal Liberation is essential reading for the supporter and the skeptic alike.--From publisher description.

In this paper I ask how we should treat other beings in cases of uncertainty about sentience. I evaluate three options: an incautionary principle that permits us to treat other beings as non-sentient, a precautionary principle that requires us to treat other beings as sentient, and an expected value principle that requires us to multiply our subjective probability that other beings are sentient by the amount of moral value they would have if they were. I then draw three conclusions. First, (...) the precautionary and expected value principles are more plausible than the incautionary principle. Second, if we accept a precautionary or expected value principle, then we morally ought to treat many beings as having at least partial moral status. Third, if we morally ought to treat many beings as having at least partial moral status, then morality involves more cluelessness and demandingness than we might have thought. (shrink)

This article examines a metaphilosophical issue, namely existing disagreements in philosophy of science about the significance of using multiple means of determination in scientific practice. We argue that this disagreement can, in part, be resolved by separating different questions that can be asked about the use of multiple means of determination, including the following: what can be concluded from the convergence of data or the convergence of claims about phenomena? Are the conclusions drawn from the convergence of data and of (...) statements about phenomena of special importance to the debate about realism and antirealism? Do inferences based on multiple means of determination have stronger epistemic force than inferences that are secured in other ways? Is the epistemic goal of deploying multiple means of determination well entrenched within the scientific community? Most of these questions can be discussed both in a formal and in an empirical perspective. If the differences in perspective are taken into account, some disagreements can be easily resolved. In part, however, the disagreements reflect historiographical challenges that are very difficult, if not impossible to meet. (shrink)

This paper analyzes the concept of biodiversity in conservation biology and assesses potential methods for its measurement.

Offers a forthright approach to the many disquieting questions surrounding the emotional debate over animal rights. This book includes a chapter on animal agriculture, and additional discussions of animal law, companion animal issues, genetic engineering, animal pain, animal research, and other topics.

We argue that the de-extinction of the mammoth cannot be ethically grounded by duties to the extinct mammoth, to ecosystem health or to individual organisms in ecosystems missing the mammoth. However, the action can be shown to be morally permissible via the goods it will afford humans, including advances in scientific knowledge, valuable experiences of awe and pleasure, and perhaps improvements to our moral character or behaviour—if and only if suffering is minimal. Finally, we call for empirical research into how (...) the possibility of the technology affects our behaviour or our character to help the debate transcend duelling intuitions. (shrink)

The position advanced in this paper is that the bedrock of emotional feelings is contained within the evolved emotional action apparatus of mammalian brains. This dual-aspect monism approach to brain–mind functions, which asserts that emotional feelings may reflect the neurodynamics of brain systems that generate instinctual emotional behaviors, saves us from various conceptual conundrums. In coarse form, primary process affective consciousness seems to be fundamentally an unconditional “gift of nature” rather than an acquired skill, even though those systems facilitate skill (...) acquisition via various felt reinforcements. Affective consciousness, being a comparatively intrinsic function of the brain, shared homologously by all mammalian species, should be the easiest variant of consciousness to study in animals. This is not to deny that some secondary processes cannot be evaluated in animals with sufficiently clever behavioral learning procedures, as with place-preference procedures and the analysis of changes in learned behaviors after one has induced re-valuation of incentives. Rather, the claim is that a direct neuroscientific study of primary process emotional/affective states is best achieved through the study of the intrinsic , albeit experientially refined, emotional action tendencies of other animals. In this view, core emotional feelings may reflect the neurodynamic attractor landscapes of a variety of extended trans-diencephalic, limbic emotional action systems—including SEEKING, FEAR, RAGE, LUST, CARE, PANIC, and PLAY. Through a study of these brain systems, the neural infrastructure of human and animal affective consciousness may be revealed. Emotional feelings are instantiated in large-scale neurodynamics that can be most effectively monitored via the ethological analysis of emotional action tendencies and the accompanying brain neurochemical/electrical changes. The intrinsic coherence of such emotional responses is demonstrated by the fact that they can be provoked by electrical and chemical stimulation of specific brain zones—effects that are affectively laden. For substantive progress in this emerging research arena, animal brain researchers need to discuss affective brain functions more openly. Secondary awareness processes, because of their more conditional, contextually situated nature, are more difficult to understand in any neuroscientific detail. In other words, the information-processing brain functions, critical for cognitive consciousness, are harder to study in other animals than the more homologous emotional/motivational affective state functions of the brain.

A comprehensive study of the ethics of killing in cases in which the metaphysical or moral status of the individual killed is uncertain or controversial. Among those beings whose status is questionable or marginal in this way are human embryos and fetuses, newborn infants, animals, anencephalic infants, human beings with severe congenital and cognitive impairments, and human beings who have become severely demented or irreversibly comatose. In an effort to understand the moral status of these beings, this book develops and (...) defends distinctive accounts of the nature of personal identity, the evaluation of death, and the wrongness of killing. The central metaphysical claim of the book is that we are neither nonmaterial souls nor human organisms but are instead embodied minds. In ethical theory, one of the central claims is that the morality of killing is not unitary; rather, the principles that determine the morality of killing in marginal cases are different from those that govern the killing of persons who are self‐conscious and rational. Another important theme is that killing in marginal cases should be evaluated in terms of the impact it would have on the victim at the time rather than on the value of the victim's life as a whole. What primarily matters is how killing would affect that which would be rational for the victim to care about at the time of death. By appealing to various foundational claims about identity, death, and the morality of killing, this book yields novel conclusions about such issues as abortion, prenatal injury, infanticide, the killing of animals, the significance of brain death, the termination of life support in cases of persistent vegetative state, the use of anencephalic infants as sources of organs for transplantation, euthanasia, assisted suicide, and advance directives in cases of dementia. In particular, the book defends the moral permissibility of abortion, infanticide, and euthanasia in certain cases and argues that brain death is not the appropriate criterion of death either for a person or a human organism.

On the orthodox view in economics, interpersonal comparisons of utility are not empirically meaningful, and "hence" impossible. To reassess this view, this paper draws on the parallels between the problem of interpersonal comparisons of utility and the problem of translation of linguistic meaning, as explored by Quine. I discuss several cases of what the empirical evidence for interpersonal comparisonsof utility might be and show that, even on the strongest of these, interpersonal comparisons are empirically underdetermined and, if we also deny (...) any appropriate truth of the matter, indeterminate. However, the underdetermination can be broken non-arbitrarily (though not purely empirically) if (i) we assign normative significance to certain states of affairs or (ii) we posit a fixed connection between certain empirically observable proxies and utility. I conclude that, even if interpersonal comparisons are not empirically meaningful, they are not in principle impossible. (shrink)

Recent advances in synthetic biology have made it possible to revive extinct species of animals, a process known as ‘de-extinction’. This paper examines two reasons for supporting de-extinction: the potential for de-extinct species to play useful roles in ecosystems; and human valuing of certain de-extinct species. I focus on the particular case of passenger pigeons to argue that the most critical challenge for de-extinction is that it entails significant suffering for sentient individual animals. I also provide reasons to take existence (...) value, or valuing the mere the fact that a species exists, into consideration in debates over de-extinction. (shrink)

I sketch briefly some of the more influential theories concerned with the moral status of nonhuman animals, highlighting their biological/physiological aspects. I then survey the most prominent empirical research on the physiological and cognitive capacities of nonhuman animals, focusing primarily on sentience, but looking also at a few other morally relevant capacities such as self-awareness, memory, and mindreading. Lastly, I discuss two examples of current animal welfare policy, namely, animals used in industrialized food production and in scientific research. I argue (...) that even the most progressive current welfare policies lag behind, are ignorant of, or arbitrarily disregard the science on sentience and cognition. (shrink)

That death is not a welfare issue appears to be a widespread view among animal welfare researchers. This paper demonstrates that this view is based on a mistaken assumption about harm, which is coupled to ‘welfare’ being conceived as ‘welfare at a time’. Assessments of welfare at a time ignore issues of longevity. In order to assess the welfare issue of death, it is necessary to structure welfare assessment as comparisons of possible lives of the animals. The paper also demonstrates (...) that excluding the welfare issues of being deprived of life from the ethical assessment of killing distorts the ethical considerations. (shrink)

"Well-being," "welfare," "utility," and "quality of life," all closely related concepts, are at the center of morality, politics, law, and economics. Griffin's book, while primarily a volume of moral philosophy, is relevant to all of these subjects. Griffin offers answers to three central questions about well-being: what is the best way to understand it, can it be measured, and where should it fit in moral and political thought. With its breadth of investigation and depth of insight, this work holds significance (...) for philosophers as well as for those interested in political and economic theory and jurisprudence.

I have been involved with the current interest in de‐extinction since early 2012, nearly its beginning. I have given a lot of thought to the potential risks and benefits of de‐extinction. But only recently, after deep immersion in discussions around CRISPR‐Cas9, the hottest new tool in bioscience since polymerase chain reaction, have I thought about a more fundamental question: how, if at all, is de‐extinction special? Are “revived species” just another kind of genetically modified organism, raising essentially the same general (...) concerns? I answer, for the most part, yes. De‐extinction is not (very) special. New biotechnologies are giving humans even more power to change the biosphere but more directly, more quickly, and more utterly than ever before. De‐extinction is just one possible, and probably small, use of those technologies. Our attention, for the most part, should be on the bigger issues of regulating this power, rather than focusing specifically on their application to de‐extinction. (shrink)

Robustness is often presented as a guideline for distinguishing the true or real from mere appearances or artifacts. Most of recent discussions of robustness have focused on the kind of derivational robustness analysis introduced by Levins, while the related but distinct idea of robustness as multiple accessibility, defended by Wimsatt, has received less attention. In this paper, I argue that the latter kind of robustness, when properly understood, can provide justification for ontological commitments. The idea is that we are justified (...) in believing that things studied by science are real insofar as we have robust evidence for them. I develop and analyze this idea in detail, and based on concrete examples show that it plays an important role in science. Finally, I demonstrate how robustness can be used to clarify the debate on scientific realism and to formulate new arguments. (shrink)

T. J. Kasperbauer presents an analysis of the ethics of de-extinction that is fairly distinctive in its focus on the welfare of individual animals. But while he is right to express concerns about individual animal well-being, individualism may not be the most important lens through which to view this issue. If one examines more closely what is at issue in de-extinction technologies in relation to species, additional problems appear that cast doubt both on the legitimacy of de-extinction projects, and on (...) the limited defense of them that Kasperbauer offers.

To study animal welfare empirically we need an objective basis for deciding when an animal is suffering. Suffering includes a wide range ofunpleasant emotional states such as fear, boredom, pain, and hunger. Suffering has evolved as a mechanism for avoiding sources ofdanger and threats to fitness. Captive animals often suffer in situations in which they are prevented from doing something that they are highly motivated to do. The an animal is prepared to pay to attain or to escape a situation (...) is an index ofhow the animal about that situation. Withholding conditions or commodities for which an animal shows (i.e., for which it continues to work despite increasing costs) is very likely to cause suffering. In designing environments for animals in zoos, farms, and laboratories, priority should be given to features for which animals show inelastic demand. The care ofanimals can thereby be based on an objective, animal-centered assessment of their needs. (shrink)

This paper is a plea for hedonism to be taken more seriously. It begins by charting hedonism's decline, and suggests that this is a result of two major objections: the claim that hedonism is the 'philosophy of swine', reducing all value to a single common denominator, and Nozick's 'experience machine' objection. There follows some elucidation of the nature of hedonism, and of enjoyment in particular. Two types of theory of enjoyment are outlined-intemalism, according to which enjoyment has some special 'feeling (...) tone'. and externalism, according to which enjoyment is any kind of experience to which we take some special attitude, such as that of desire. lnternalism-the traditional view--is defended against current externalist orthodoxy. The paper ends with responses to the philosophy of swine and the experience machine objections. (shrink)

“de-extinction” refers to the process of resurrecting extinct species by genetic methods. This science-fiction-sounding idea is in fact already in early processes of scientific implementation. Although this recent “revival of the dead” raises deep ethical questions, the ethics of de-extinction has barely received philosophical treatment. Rather than seeking a verdict for or against de-extinction, this paper attempts an overview and some novel analyses of the main ethical considerations. Five dimensions of the ethics of de-extinction are explored: (a) the possible contribution (...) of de-extinction to promoting ecological values, (b) the deontological argument that we owe de-extinction to species we rendered extinct, (c) the question of “playing God” through de-extinction, (d) the utilitarian perspective, and (e) the role of aesthetic considerations in the ethics of de-extinction. A general feature arising from the paper’s discussion is that, due to de-extinction’s special character, it repeatedly tests the limits of our ethical notions. (shrink)

This introductory article describes the phenomena of incommensurability and incomparability, how they are related, and why they are important. Since incomparability is the more significant phenomenon, the paper takes that as its focus. It gives a detailed account of what incomparability is, investigates the relation between the incomparability of values and the incomparability of alternatives for choice, distinguishes incomparability from the related phenomena of parity, indeterminacy, and noncomparability, and, finally, defends a view about practical justification that vindicates the importance of (...) incomparability — assuming it exists — for practical reason.

Among the most egregious and discouraging problems of conservation is the rapidly escalating human‐caused species extinction rate. “De‐extinction” refers to the application of certain cutting‐edge techniques for the supposed recovery of lost species and gives the impression that scientists, enlightened and empowered by the miracles of technology, are coming to the rescue. “De‐extinction” is the latest example of a long play of language that has given conservation efforts a tragically false sense of accomplishment and has worsened the conservation crisis. De‐extinction (...) is the tip of an intellectual iceberg that sits atop of a host of profoundly questionable value systems, expectations, attitudes, and priorities that elude and bewitch critical reflection. It gives the impression that extinction is reversible and, thus, diminishes the gravity of the human annihilation of species. Here, we examine how the language of de‐extinction influences attitudes, shapes thoughts and imagination, and creates ethical blindness. The language developing around “de‐extinction” reveals what is in fact a profound intellectual crisis at the foundation of conservation. The underlying challenge is to find the language that will articulate and inspire the radical and indispensable change needed to come to grips with the value of nature. (shrink)

This review of Wimsatt’s book Re-engineering Philosophy for Limited Beings focuses on analysing his use of robustness, a central theme in the book. I outline a family of three distinct conceptions of robustness that appear in the book, and look at the different roles they play. I briefly examine what underwrites robustness, and suggest that further work is needed to clarify both the structure of robustness and the relation between it various conceptions.

De-extinction is the process through which extinct species can be brought back into existence. Although these projects have the potential to cause great harm to animal welfare, discussion on issues surrounding de-extinction have focussed primarily on other issues. In this paper, I examine the potential types of welfare harm that can arise through de-extinction programs, including problems with cloning, captive rearing and re-introduction. I argue that welfare harm should be an important consideration when making decisions on de-extinction projects. Though most (...) of the proposed benefits of these projects are insufficient to outweigh the current potential welfare harm, these problems may be overcome with further development of the technology and careful selection of appropriate species as de-extinction candidates.

The practice of ‘management euthanasia’, in which zoos kill otherwise healthy surplus animals, is a controversial one. The debate over the permissibility of the practice tends to divide along two different views in animal ethics—animal rights and animal welfare. Traditionally, those arguments against the practice have come from the animal rights camp, who see it as a violation of the rights of the animal involved. Arguments in favour come from the animal welfare perspective, who argue that as the animal does (...) not suffer, there is no harm in the practice and it is justified by its potential benefits. Here, I argue that an expansion of the welfare view, encompassing longevity and opportunities for positive welfare, give stronger considerations against management euthanasia, which then require greater benefits to justify its use.

The size of animal exhibits has important effects on their lives and welfare. However, most references to exhibit size only consider floor space and height dimensions, without considering the space afforded by usable features within the exhibit. In this paper, we develop two possible methods for measuring the usable space of zoo exhibits and apply these to a sample exhibit. Having a metric for usable space in place will provide a better reflection of the quality of different exhibits, and enhance (...) comparisons between exhibits. (shrink)

Different brain mechanisms seem to mediate wanting and liking for the same reward.
