Though the vegetarian movement sparked by Peter Singer’s book Animal Liberation has achieved some success, there is more animal suffering caused today due to factory farming than there was when the book was originally written. In this paper, I argue that there may be a technological solution to the problem of animal suffering in intensive factory farming operations. In particular, I suggest that recent research indicates that we may be very close to, if not already at, the point where we (...) can genetically engineer factory-farmed livestock with a reduced or completely eliminated capacity to suffer. In as much as animal suffering is the principal concern that motivates the animal welfare movement, this development should be of central interest to its adherents. Moreover, I will argue that all people concerned with animal welfare should agree that we ought to replace the animals currently used in factory farming with animals whose ability to suffer is diminished if we are able to do so.

In recent years, humans’ ability to selectively modify genes has increased dramatically as a result of the development of new, more efficient, and easier genetic modification technology. In this paper, we argue in favor of using this technology to improve the welfare of agricultural animals. We first argue that using animals genetically modified for improved welfare is preferable to the current status quo. Nevertheless, the strongest argument against pursuing gene editing for welfare is that there are alternative approaches to addressing (...) some of the challenges of modern agriculture that may offer ethical advantages over genetic modification; namely, a dramatic shift towards plant-based diets or the development of in vitro meat. Nevertheless, we provide reasons for thinking that despite these possible comparative disadvantages there are important reasons for continuing the pursuit of welfare improvements via genetic modification.

Many traditional attempts to show that nonhuman animals are deserving of moral consideration have taken the form of an argument by analogy. However, arguments of this kind have had notable weaknesses and, in particular, have not been able to convince two kinds of skeptics. One of the most important weaknesses of these arguments is that they fail to provide theoretical justifications for why particular physiological similarities should be considered relevant. This paper examines recent empirical research on pain and, in particular, (...) explores the implications of the dissociation between the sensory and the affective pain pathways. It is argued that these results show that the belief that nonhuman animals experience pain in a morally relevant way is reasonable, though not certain. It is further argued that the proposal to explore the relationship between consciousness and various forms of learning challenges the aforementioned skeptics to provide more physiological details for their claims that nonhuman mammals are probably not conscious.

Recent results from the neurosciences demonstrate that pleasure and pain are not two symmetrical poles of a single scale of experience but in fact two different types of experiences altogether, with dramatically different contributions to well-being. These differences between pleasure and pain and the general finding that “the bad is stronger than the good” have important implications for our treatment of nonhuman animals. In particular, whereas animal experimentation that causes suffering might be justified if it leads to the prevention of (...) more suffering, it can never by justified merely by leading to increased levels of happiness.

Growing awareness of the ethical implications of neuroscience in the early years of the 21st century led to the emergence of the new academic field of “neuroethics,” which studies the ethical implications of developments in the neurosciences. However, despite the acceleration and evolution of neuroscience research on nonhuman animals, the unique ethical issues connected with neuroscience research involving nonhuman animals remain underdiscussed. This is a significant oversight given the central place of animal models in neuroscience. To respond to these concerns, (...) the Center for Neuroscience and Society and the Center for the Interaction of Animals and Society at the University of Pennsylvania hosted a workshop on the “Neuroethics of Animal Research” in Philadelphia, Pennsylvania. At the workshop, expert speakers and attendees discussed ethical issues arising from neuroscience research involving nonhuman animals, including the use of animal models in the study of pain and psychiatric conditions, animal brain-machine interfaces, animal–animal chimeras, cerebral organoids, and the relevance of neuroscience to debates about personhood. This paper highlights important emerging ethical issues based on the discussions at the workshop. This paper includes recommendations for research in the United States from the authors based on the discussions at the workshop, loosely following the format of the 2 Gray Matters reports on neuroethics published by the Presidential Commission for the Study of Bioethical Issues.

Peter Carruthers argues that phenomenal consciousness might not matter very much either for the purpose of determining which nonhuman animals are appropriate objects of moral sympathy, or for the purpose of explaining for the similarities in behavior of humans and nonhumans. Carruthers bases these claims on his version of a dispositionalist higher-order thought (DHOT) theory of consciousness which allows that much of human behavior is the result of first-order beliefs that need not be conscious, and that prima facie judgments about (...) the importance of consciousness are due to confabulation. We argue briefly against his claim that 'the moral landscape can remain unchanged' even if all or nearly all nonhuman animals are taken to be incapable of conscious experience. We then show how a first-order representational (FOR) theory of consciousness might be defended against Carruthers' criticisms. Finally, we argue that Carruthers' appeal to confabulation undercuts his own arguments for an evolutionary explanation for consciousness, posing a greater epiphenomenalist threat to his DHOT theory than he concedes.

Many ethicists writing about well-being have assumed that claims made about the relationship between pleasure and well-being carry similar implications for the relationship between pain and well-being. I argue that the current neuroscience of pleasure and pain does not support this assumption. In particular, I argue that the experiences of pleasure and pain are mediated by different cognitive systems, that they make different contributions to human behavior in general and to well-being in particular, and that they bear fundamentally different relationships (...) to our motivational systems and hence desires. I further argue that though there is ample evidence that pleasure can be dissociated from appetitive motivation, there is no compelling evidence suggesting that the unpleasantness of pain can be dissociated from the aversive motivational force of pains. I consider several objections to this claim, including Jennifer Corns’ recent arguments that the unpleasantness of pain experience can be dissociated from the motivational signal of pain, before briefly drawing some lessons for ethics.

Carruthers argues that an integrated faculty of metarepresentation evolved for mindreading and was later exapted for metacognition. A more consistent application of his approach would regard metarepresentation in mindreading with the same skeptical rigor, concluding that the “faculty” may have been entirely exapted. Given this result, the usefulness of Carruthers’ line-drawing exercise is called into question.

Abstract:Human and animal research both operate within established standards. In the United States, criticism of the human research environment and recorded abuses of human research subjects served as the impetus for the establishment of the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research, and the resulting Belmont Report. The Belmont Report established key ethical principles to which human research should adhere: respect for autonomy, obligations to beneficence and justice, and special protections for vulnerable individuals and (...) populations. While current guidelines appropriately aim to protect the individual interests of human participants in research, no similar, comprehensive, and principled effort has addressed the use of (nonhuman) animals in research. Although published policies regarding animal research provide relevant regulatory guidance, the lack of a fundamental effort to explore the ethical issues and principles that should guide decisions about the potential use of animals in research has led to unclear and disparate policies. Here, we explore how the ethical principles outlined in the Belmont Report could be applied consistently to animals. We describe how concepts such as respect for autonomy and obligations to beneficence and justice could be applied to animals, as well as how animals are entitled to special protections as a result of their vulnerability.

This edited volume represents a unique addition to the available literature on animal ethics, animal studies, and neuroethics. Its goal is to expand discussions on animal ethics and neuroethics by weaving together different threads: philosophy of mind and animal minds, neuroscientific study of animal minds, and animal ethics. Neuroethical questions concerning animals’ moral status, animal minds and consciousness, animal pain, and the adequacy of animal models for neuropsychiatric disease have long been topics of debate in philosophy and ethics, and more (...) recently also in neuroscientific research. The book presents a transdisciplinary blend of voices, underscoring different perspectives on the broad questions of how neuroscience can contribute to our understanding of nonhuman minds, and on debates over the moral status of nonhuman animals. All chapters were written by outstanding scholars in philosophy, neuroscience, animal behavior, biology, neuroethics, and bioethics, and cover a range of issues and species/taxa. Given its scope, the book will appeal to scientists and students interested in the debate on animal ethics, while also offering an important resource for future researchers. Chapter 13 of this book is available open access under a CC BY 4.0 license at link.springer.com. (shrink)

We submit this brief in support of the Nonhuman Rights Project’s efforts to secure habeas corpus relief for the elephant named Happy. The Supreme Court, Bronx County, declined to grant habeas corpus relief and order Happy’s transfer to an elephant sanctuary, relying, in part, on previous decisions that denied habeas relief for the NhRP’s chimpanzee clients, Kiko and Tommy. Those decisions use incompatible conceptions of ‘person’ which, when properly understood, are either philosophically inadequate or, in fact, compatible with Happy’s personhood.

In this brief, we argue that there is a diversity of ways in which humans (Homo sapiens) are ‘persons’ and there are no non-arbitrary conceptions of ‘personhood’ that can include all humans and exclude all nonhuman animals. To do so we describe and assess the four most prominent conceptions of ‘personhood’ that can be found in the rulings concerning Kiko and Tommy, with particular focus on the most recent decision, Nonhuman Rights Project, Inc v Lavery.

Shriver and Allen (this volume, this journal; hereafter S&A) make three unconnected criticisms of my views concerning phenomenal consciousness and the question of animal consciousness. First, they claim that my dispositional higher-order thought theory of consciousness has much greater significance for ethics than I recognize. Second, they claim that, in the course of attempting to motivate that theory, I have presented inadequate criticisms of first-order theories (according to which phenomenal consciousness may well be rampant in the animal world). And (...) third, they claim that my argument that the question of animal consciousness might not matter a great deal for comparative psychology may prove too much, showing that such consciousness is genuinely epiphenomenal in ourselves, and undermining some of my own evolutionary arguments in support of higher-order theories. I shall focus mostly on the second and third criticisms. But I begin with a few remarks about the first. (shrink)

This highly readable book is a collection of critical papers on Otto Neurath. It comprehensively re-examines Neurath’s scientific, philosophical and educational contributions from a range of standpoints including historical, sociological and problem-oriented perspectives. Leading Neurath scholars disentangle and connect Neurath’s works, ideas and ideals and evaluate them both in their original socio-historical context and in contemporary philosophical debates. Readers will discover a new critical understanding. Drawing on archive materials, essays discuss not only Neurath’s better-known works from lesser-known perspectives, but also (...) his lesser-known works from the better-known perspective of their place in his overall philosophical oeuvre. Reflecting the full range of Neurath's work, this volume has a broad appeal. Besides scholars and researchers interested in Neurath, Carnap, the Vienna Circle, work on logical empiricism and the history and philosophy of science, this book will also appeal to graduate students in philosophy, sociology, history and education. Readers will find Neurath’s thoughts described and evaluated in an accessible manner, making it a good read for those beyond the academic world such as social leaders and activists. The book includes the edited 1940-45 Neurath-Carnap correspondence and the English translation of Neurath's logic papers. (shrink)

This book reconceives virtue epistemology in light of the conviction that we are essentially social creatures. Virtue is normally thought of as something that allows individuals to accomplish things on their own. Although contemporary ethics is increasingly making room for an inherently social dimension in moral agency, intellectual virtues continue to be seen in terms of the computing potential of a brain taken by itself. Thinking in these terms, however, seriously misconstrues the way in which our individual flourishing hinges on (...) our collective flourishing. Green’s account of virtue epistemology is based on the extended credit view, which conceives of knowledge as an achievement and broadens that focus to include team achievements in addition to individual ones. He argues that this view does a better job than alternatives of answering the many conceptual and empirical challenges for virtue epistemology that have been based on cases of testimony. The view also allows for a nuanced interaction with situationist psychology, dual processing models in cognitive science, and the extended mind literature in philosophy of mind. This framework provides a useful conceptual bridge between individual and group epistemology, and it has novel applications to the epistemology of disagreement, prejudice, and authority. (shrink)

Most accounts of “logical empiricism in America” take logical empiricism to be a monolithic, or at least a one-dimensional, philosophical group. This picture of logical empiricism has come under well-reasoned attack during the past two decades, but some of the relevant conclusions for the reception-history of the movement were not drawn, or were not drawn as thoroughly as they could have been. Thus, if we want to understand the reception of logical empiricism, we should not talk about the reception of (...) logical empiricism as such; rather, we should provide a more stratified and differently balanced account. This article aims to draw the contours of one more stratified account by pointing out differences in the reception-history of logical empiricism with respect to pragmatism in particular. Namely, I will examine and defend an account according to which the more pragmatist-naturalist wing of logical empiricism was welcomed by the majority of American pragmatists while the more technical wing came immediately under pragmatist attack from various sides.

Growing concern has been expressed that we have entered a “post-truth” era in which each of us willfully believes whatever we choose, aided and abetted by alternative and social media that spin alternative realities for boutique consumption. A prime example of the belief in alternative realities is said to be acceptance of “conspiracy theories”—a term that is often used as a pejorative to indict claims of conspiracy that are so obviously absurd that only the unhinged could believe them. The epistemological (...) standard often involved in this indictment, however—the standard of “obvious” falsity—invites subjectivity in its application, because what is obviously false to one person can be common sense to another. This is not just a truism; considerable research suggests that people’s political beliefs, in general, and their acceptance or rejection of conspiracy theories in particular, tends in large part to be determined by partisan, ideological, and other priors.

In a recent monograph, Sandy Goldberg argues that epistemology should be renovated so as to accommodate the way in which human beings are dependent on others for what they know. He argues that the way to accomplish this is to consider the cognition of others to be part of the belief-forming process for the purposes of epistemic assessment when radical dependence on others is in evidence. In this paper, I argue that, contrary to what one may expect, a credit theory (...) of knowledge is well positioned to make the sort of anti-individualistic move that Goldberg advocates. Furthermore, unlike Goldberg's extended process reliabilism, an extended credit theory has a theoretically motivated way of restricting the domain of epistemic evaluation to the cognitive. Finally, I argue that, although adopting the extended cognition hypothesis would help Goldberg's position, an extended credit theory would still have the advantage. (shrink)

This paper considers the prospect of moral transhumanism from the perspective of theological virtue ethics. I argue that the pursuit of goodness inherent to moral transhumanism means that there is a compelling prima facie case for moral enhancement. However, I also show that the proposed enhancements would not by themselves allow us to achieve a life of virtue, as they appear unable to create or enhance prudence, the situational judgement essential for acting in accordance with virtue. I therefore argue that (...) moral enhancement technologies should take a limited or supporting role in moral development, which I call ‘moral supplementation’. (shrink)

Human beings are promiscuously social creatures, and contemporary epistemologists are increasingly becoming aware that this shapes the ways in which humans process information. This awareness has tended to restrict itself, however, to testimony amongst isolated dyads. As scientific practice ably illustrates, information-processing can be spread over a vast social network. In this essay, a credit theory of knowledge is adapted to account for the normative features of strongly distributed cognition. A typical credit theory analyzes knowledge as an instance of obtaining (...) success because of or through the ability of the individual knower. The extended credit theory developed here broadens this framework so as to accommodate team-like epistemic achievements. The extended credit theory is then contrasted with some similar proposals given from within a process reliabilist framework. Once one isolates pairs of cases of distributed cognition in which there is a difference between sheer reliability and reliability grounded in ability, one can see that the extended credit theory maps the normative terrain better than the alternatives.

In the Typic chapter of the Critique of Practical Reason, Kant aims to enable moral judgment by means of the law of nature, which serves as the ‘type’, or formal analogue, of moral law. The present monograph is the first comprehensive study of this key text. It provides a detailed commentary on the Typic, situates it within Kant’s ethics and his theory of symbolic representation, and critically engages with the relevant secondary literature.

This edited collection provides the first comprehensive volume on A. J. Ayer’s 1936 masterpiece, Language, Truth and Logic. With eleven original chapters the volume reconsiders the historical and philosophical significance of Ayer’s work, examining its place in the history of analytic philosophy and its subsequent legacy. Making use of pioneering research in logical empiricism, the contributors explore a wide variety of topics, from ethics, values and religion, to truth, epistemology and philosophy of language. Among the questions discussed are: How did (...) Ayer preserve or distort the views and conceptions of logical empiricists? How are Ayer's arguments different from the ones he aimed at reconstructing? And which aspects of the book were responsible for its immense impact? The volume expertly places Language, Truth and Logic in the intellectual and socio-cultural history of twentieth-century philosophical thought, providing both introductory and contextual chapters, as well as specific explorations of a variety of topics covering the main themes of the book. Providing important insights of both historical and contemporary significance, this collection is an essential resource for scholars interested in the legacy of the Vienna Circle and its effect on ethics and philosophy of mind.

Jennifer Lackey presents a puzzle to which she argues there is no current solution. Lackey's claim is that testimonial knowledge can have something conspicuously wrong with it and still be knowledge. Testimonial knowledge can be ‘deficient’. Given that knowledge is a normative category, that it describes what it is for a belief to go right, there is a puzzle that comes with accounting for how a testimonial belief could be knowledge and yet go wrong in the ways Lackey has in (...) mind. In this paper, I argue that the deficiency is one of teamwork, and that Lackey's puzzle offers one a window into the respect in which testimony is a kind of team achievement. (shrink)

This paper offers an analysis of work on human development in evolutionary anthropology from a Thomist perspective. I show that both fields view care for others as fundamental to human nature and interpret cooperative breeding as expression of the virtue of charity. I begin with an analysis of different approaches to the relationship between evolutionary anthropology and moral theory. I argue that ethical naturalism is the approach best suited to interdisciplinary dialogue, since it holds that natural facts are useful for (...) moral theory but do not encompass it. This forms the basis for a Thomist analysis of some key features of human evolution including bipedalism, higher encephalisation and extended childhood. In each case I explain how these parts of our nature contributed to the evolution of modern humans, and how each is reliant upon communal care. Finally, I offer three observations on these facts from a Thomist perspective. Firstly, that a good human life necessarily involves caring for others and being cared for ourselves. Secondly, that this is exemplified in the virtue of charity, which is the ground of all virtue. Finally, that the need for such care shows that human flourishing cannot be attained without divine aid. (shrink)

C.H. Waddington is today remembered chiefly as a Drosophila developmental geneticist who developed the concepts of “canalization” and “the epigenetic landscape.” In his lifetime, however, he was widely perceived primarily as a critic of Neo-Darwinian evolutionary theory. His criticisms of Neo-Darwinian evolutionary theory were focused on what he saw as unrealistic, “atomistic” models of both gene selection and trait evolution. In particular, he felt that the Neo-Darwinians badly neglected the phenomenon of extensive gene interactions and that the “randomness” of mutational (...) effects, posited in the theory, was a false postulate. This last criticism dealt with the phenomenon known today as “developmental constraints.” Although population genetics itself has evolved considerably from its form at mid-20th century, much of Waddington’s critique, it is argued here, retains cogency. Yet, he did not attempt to develop a full-fledged alternative theory himself. Perhaps most surprisingly, in retrospect, is that he did not try to marry his work on gene interactions in development with his evolutionary interests, to create a theory of “genetic networks” and their evolution. Whether evolutionary genetics today will incorporate “network thinking” as a central element or whether there will be a general retreat to the more atomistic approach offered by genomics, remains an open question.

Rather than being in inherent conflict with religion or operating on planes that do not intersect, the cognitive science of religion (CSR) can be used to renovate a religious understanding of the world. CSR allows one to reshape the perspectives of Aquinas and Calvin on the natural knowledge of God. The Christian tradition affirms that all human beings have available to them some knowledge of God. This claim has empirical import and thus invites scientific investigation and clarification. A CSR-inspired lens (...) allows one’s theological reflections to move from paradigms that focus on the cognitive reach of a domain-general power of human thought to a paradigm focused on different ways of relating to another person. The case study of the natural knowledge of God presented here models a productive way of relating CSR and religious perspectives from within a faith tradition. (shrink)
