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.

Optogenetics is an invasive neuromodulation technology involving the use of light to control the activity of individual neurons. Even though optogenetics is a relatively new neuromodulation tool whose various implications have not yet been scrutinized, it has already been approved for its first clinical trials in humans. As optogenetics is being intensively investigated in animal models with the aim of developing novel brain stimulation treatments for various neurological and psychiatric disorders, it appears crucial to consider both the opportunities and (...) dangers such therapies may offer. In this review, we focus on the memory-modifying potential of optogenetics, investigating what it is capable of and how it differs from other memory modification technologies. We then outline the safety challenges that need to be addressed before optogenetics can be used in humans. Finally, we re-examine crucial neuroethical concerns expressed in regard to other MMTs in the light of optogenetics and address those that appear to be unique to the memory-modifying potential of optogenetic technology.

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.

What can neuroscience tell us, if anything, about the capacities of cows to think about the future? The question is important if having the right to a future requires the ability to think about one’s future. To think about one’s future involves the mental state of prospection, in which we direct our attention to things yet to come. I distinguish several kinds of prospection, identify the behavioral markers of future thinking, and survey what is known about the neuroanatomy of future-directed (...) bovine beliefs and desires. I suggest, in conclusion, that instead of asking whether a cow’s prospection is conscious, ask whether it is like ours—with “ours” understood to include all human beings. (shrink)

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.

Recent work in moral theory has seen the refinement of theories of moral standing, which increasingly recognize a position of intermediate standing between fully self-conscious entities and those which are merely conscious. Among the most sophisticated concepts now used to denote such intermediate standing is that of primitive self-consciousness, which has been used to more precisely elucidate the moral standing of human newborns. New research into the structure of the avian brain offers a revised view of the cognitive abilities of (...) birds. When this research is approached with a species-specific focus, it appears likely that one familiar species, the chicken (Gallus gallus domesticus), also exhibits primitive self-consciousness. Given the likelihood that they are primitively self-consciousness, chickens warrant a degree of moral standing that falls short of that enjoyed by persons, but which exceeds the minimal standing of merely conscious entities.

There has been a growing interest in research concerning memory modification technologies (MMTs) in recent years. Neuroscientists and psychologists are beginning to explore the prospect of controllable and intentional modification of human memory. One of the technologies with the greatest potential to this end is optogenetics—an invasive neuromodulation technique involving the use of light to control the activity of individual brain cells. It has recently shown the potential to modify specific long-term memories in animal models in ways not yet (...) possible with other MMTs. As the therapeutic potential of optogenetics has already prompted approval of the first human trials, it is especially important and timely to consider the opportunities and dangers this technology may entail. In this article, we focus on possible consequences of optogenetics as an MMT by analyzing fundamental threats potentially associated with memory modifications: the potential disruption of personality and authenticity.

In bioethics, the first decade of the twenty-first century was characterized by the emergence of interest in the ethical, legal, and social aspects of neuroscience research. At the same time an ongoing extension of the topics and phenomena addressed by neuroscientists was observed alongside its rise as one of the leading disciplines in the biomedical science. One of these phenomena addressed by neuroscientists and moral psychologists was the neural processes involved in moral decision-making. Today both strands of research are often (...) addressed under the label of neuroethics. To understand this development we recalled literature from 1995 to 2012 stored in the Mainz Neuroethics Database (i) to investigate the quantitative development of scientific publications in neuroethics; (ii) to explore changes in the topics of neuroethics research within the defined time interval; (iii) to illustrate the interdependence of different research topics within the neuroethics literature; (iv) to show the development of the distribution of neuroethics research on peer-reviewed journals; and (v) to display the academic background and affiliations of neuroethics Researchers ...

Laura Specker Sullivan (2022) makes a fairly compelling case for the value of the perspectives of Buddhist practitioners in neuroethics. In this study, Tibetan Buddhist monks have been asked, among other things, whether consciousness, in brain-injured patients in a minimally conscious state, entails a duty to preserve life. In our view, some of the participants’ responses could be used to inform the bioethical debate on death determination.

Neuroethics is the body of work exploring the ethical, legal, and social implications of neuroscience. This work can be separated into two rough categories. The neuroscience of ethics concerns a neuroscientific understanding of the brain processes that underpin moral judgment and behavior. The ethics of neuroscience, on the other hand, includes the potential impact advances in neuroscience may have on social, moral and philosophical ideas and institutions, as well as the ethical principles that should guide brain research, treatment of (...) brain disease, and cognitive enhancement. Central to the questions posed in neuroethics is the way in which neuroscience might impact our sense of self and personal responsibility, and our understanding the structure of moral judgments.

In debates about animal sentience, the precautionary principle is often invoked. The idea is that when the evidence of sentience is inconclusive, we should “give the animal the benefit of the doubt” or “err on the side of caution” in formulating animal protection legislation. Yet there remains confusion as to whether it is appropriate to apply the precautionary principle in this context, and, if so, what “applying the precautionary principle” means in practice regarding the burden of proof (...) for animal sentience. Here I construct a version of the precautionary principle tailored to the question of animal sentience together with a practical framework for implementing it. I explain and defend the key features of this framework, argue that it is well-aligned with current practice in animal welfare science, and consider and reject a number of influential counterarguments to the use of precautionary reasoning in this area.

In Animal Ethics in Context, Clare Palmer tries to harmonise two competing approaches to animal ethics. One focuses on the morally relevant capacities that animals possess. The other is the Laissez-Faire Intuition (LFI): the claim that we have duties to assist domesticated animals but should (at least generally) leave wild animals alone. In this paper, I critique the arguments that Palmer offers in favour of the No-Contact LFI - the view that we have (prima facie) duties not to (...) harm wild animals but no duties to assist them. I argue that Palmer's endorsement of the No-Contact LFI is unwarranted. Her arguments actually provide strong reasons to endorse what I call the Gradient View - a position that posits weak presumptive duties to assist wild animals that become stronger as our relations with the animals grow stronger.

Observations of animals engaging in apparently moral behavior have led academics and the public alike to ask whether morality is shared between humans and other animals. Some philosophers explicitly argue that morality is unique to humans, because moral agency requires capacities that are only demonstrated in our species. Other philosophers argue that some animals can participate in morality because they possess these capacities in a rudimentary form. Scientists have also joined the discussion, and their views are just as varied as (...) the philosophers’. Some research programs examine whether animals countenance specific human norms, such as fairness. Other research programs investigate the cognitive and affective capacities thought to be necessary for morality. There are two sets of concerns that can be raised by these debates. They sometimes suffer from there being no agreed upon theory of morality and no clear account of whether there is a demarcation between moral and social behavior; that is, they lack a proper philosophical foundation. They also sometimes suffer from there being disagreement about the psychological capacities evident in animals. Of these two sets of concerns—the nature of the moral and the scope of psychological capacities—we aim to take on only the second. In this chapter we defend the claim that animals have three sets of capacities that, on some views, are taken as necessary and foundational for moral judgment and action. These are capacities of care, capacities of autonomy, and normative capacities. Care, we argue, is widely found among social animals. Autonomy and normativity are more recent topics of empirical investigation, so while there is less evidence of these capacities at this point in our developing scientific knowledge, the current data is strongly suggestive.

We argue that animals are not cognitively stuck in time. Evidence pertaining to multisensory temporal order perception strongly suggests that animals can represent at least some temporal relations of perceived events.

The study of animal cognition raises profound questions about the minds of animals and philosophy of mind itself. Aristotle argued that humans are the only animal to laugh, but in recent experiments rats have also been shown to laugh. In other experiments, dogs have been shown to respond appropriately to over two hundred words in human language. In this introduction to the philosophy of animal minds Kristin Andrews introduces and assesses the essential topics, problems and debates as (...) they cut across animal cognition and philosophy of mind. She addresses the following key topics: what is cognition, and what is it to have a mind? What questions should we ask to determine whether behaviour has a cognitive basis? the science of animal minds explained: ethology, behaviourist psychology, and cognitive ethology rationality in animals animal consciousness: what does research into pain and the emotions reveal? What can empirical evidence about animal behaviour tell us about philosophical theories of consciousness? does animal cognition involve belief and concepts; do animals have a ‘Language of Thought’? animal communication other minds: do animals attribute ‘mindedness’ to other creatures? moral reasoning and ethical behaviour in animals animal cognition and memory. Extensive use of empirical examples and case studies is made throughout the book. These include Cheney and Seyfarth’s ververt monkey research, Thorndike’s cat puzzle boxes, Jensen’s research into humans and chimpanzees and the ultimatum game, Pankseep and Burgdorf’s research on rat laughter, and Clayton and Emery’s research on memory in scrub-jays. Additional features such as chapter summaries, annotated further reading and a glossary make this an indispensable introduction to those teaching philosophy of mind, animal cognition. It will also be an excellent resource for those in fields such as ethology, biology and psychology. (shrink)

According to the extended cognition thesis, an agent’s cognitive system can sometimes include extracerebral components amongst its physical constituents. Here, we show that such a view of cognition has an unjustifiably anthropocentric focus, for it tends to depict cognitive extensions as a human-only affair. In contrast, we will argue that if human cognition extends, then the cognition of many non-human animals extends too, for many non-human animals rely on the same cognition-extending strategies humans rely on. To substantiate this claim, we (...) will proceed as follows. First (Sect. 1), we will introduce the extended cognition thesis, exposing its anthropocentric bias. Then, we will show that humans and many non-human animals rely on the same cognition-extending strategies. To do so, we will discuss a variety of case studies, including “intrabodily” cognitive extensions such as the spinal cord (Sect. 2), the widespread reliance on epistemic actions to solve cognitive tasks (Sect. 3) and cases of animal cognitive offloading (Sect. 4). We’ll then allay some worries our claim might raise (Sect. 5) to then conclude the paper (Sect. 6). (shrink)

We welcome Mikhalevich & Powell’s (2020) (M&P) call for a more “‘inclusive”’ animal ethics, but we think their proposed shift toward a moral framework that privileges false positives over false negatives will require radically revising the paradigm assumption in animal research: that there is a clear line to be drawn between sentient beings that are part of our moral community and nonsentient beings that are not.

Animal welfare scientists face an acute version of the problem of inductive risk, since they must choose whether to affirm attributions of mental states to animals in advisory contexts, knowing their decisions hold consequences for animal welfare. In such contexts, the burden of proof should be sensitive to the consequences of error, but a framework for setting appropriate burdens of proof is lacking. Through reflection on two cases—pain and cognitive enrichment—I arrive at a tentative framework based on the (...) principle of expected welfare maximization. I then discuss the limitations of this framework and the questions it leaves open. (shrink)

Though many ethicists have the intuition that we should leave nature alone, Kyle Johannsen argues that we have a duty to research safe ways of providing large-scale assistance to wild animals. Using concepts from moral and political philosophy to analyze the issue of wild animal suffering (WAS), Johannsen explores how a collective, institutional obligation to assist wild animals should be understood. He claims that with enough research, genetic editing may one day give us the power to safely intervene without (...) perpetually interfering with wild animals’ liberties.---------------Questions addressed include: In what way is nature valuable and is interference compatible with that value? Is interference a requirement of justice? What are the implications of WAS for animal rights advocacy? What types of intervention are promising?---------------Expertly moving the debate about human relations with wild animals beyond its traditional confines, Wild Animal Ethics is essential reading for students and scholars of political philosophy and political theory studying animal ethics, environmental ethics, and environmental philosophy.

The main message of Neuroethics is that neuroscience forces us to reconceptualize human agency as marvelously diverse and flexible. Free will can arise from unconscious brain processes. Individuals with mental disorders, including addiction and psychopathy, exhibit more agency than is often recognized. Brain interventions should be embraced with cautious optimism. Our moral intuitions, which arise from entangled reason and emotion, can generally be trusted. Nevertheless, we can and should safely enhance our brain chemistry, partly because motivated reasoning crops up (...) in everyday life and in the practice of neuroscience itself. Despite serious limitations, brain science can be useful in the courtroom and marketplace. Recognizing all this nuance leaves little room for anxious alarmism or overhype and urges an emphasis on neurodiversity. The result is a highly opinionated tour of neuroethics as an exciting field full of implications for philosophy, science, medicine, law, and public policy. (shrink)

Animals have moral status, and we have corresponding obligations to take their interests into account. I argue that Stakeholder Theory provides a moderate, yet principled way for businesses to do so. Animals ought to be treated as stakeholders given that they affect and are affected by the achievement of the objectives of the businesses in which they are involved. Stakeholder Theory therefore requires taking those interests into account. It does not, however, require that they be given the same weight as (...) human interests. By taking the stakeholder approach, businesses can avoid merely reacting to (rapidly increasing) public outcry over the treatment of animals. Even those who hold extreme positions—that businesses have no obligations to animals, or that animal products and services are inherently immoral—can take the treatment of animals as stakeholders to provide an ethical realpolitik of sorts that is both better for animals and better for business.

In this paper, we argue that scientists working on the animal morality debate have been operating with a narrow view of morality that prematurely limits the variety of moral practices that animals may be capable of. We show how this bias can be partially corrected by paying more attention to the touch behaviours of animals. We argue that a careful examination of the ways in which animals engage in and navigate touch interactions can shed new light on current debates (...) on animal morality, like the study of consolation behaviour, while also revealing further forms that animal morality may take and that have been neglected so far, like capacities of tolerance or trust. This defence is structured as an analysis of the three main functions of touch: the discriminative function, the affiliative function, and the vigilance function. (shrink)

The purpose of this article is to show that animal rights are not necessarily at odds with the use of animals for research. If animals hold basic moral rights similar to those of humans, then we should consequently extend the ethical requirements guiding research with humans to research with animals. The article spells out how this can be done in practice by applying the seven requirements for ethical research with humans proposed by Ezekiel Emanuel, David Wendler and Christine Grady (...) to animal research. These requirements are i) social value, ii) scientific validity, iii) independent review, iv) fair subject selection, v) favorable risk-benefit ratio, vi) informed consent, and vii) respect for research subjects. In practice, this means that we must reform the practice of animal research to make it more similar to research with humans, rather than completely abolish the former. Indeed, if we banned animal research altogether, then we would also deprive animals of its potential benefits – which would be ethically problematic. (shrink)

It has been argued that some animals are moral subjects, that is, beings who are capable of behaving on the basis of moral motivations. In this paper, we do not challenge this claim. Instead, we presuppose its plausibility in order to explore what ethical consequences follow from it. Using the capabilities approach, we argue that beings who are moral subjects are entitled to enjoy positive opportunities for the flourishing of their moral capabilities, and that the thwarting of these capabilities entails (...) a harm that cannot be fully explained in terms of hedonistic welfare. We explore the implications of this idea for the assessment of current practices involving animals. (shrink)

In this paper, I aim to show that agency-based accounts of moral status are more plausible than many have previously thought. I do this by developing a novel account of moral status that takes agency, understood as the capacity for intentional action, to be the necessary and sufficient condition for the possession of moral status. This account also suggests that the capacities required for sentience entail the possession of agency, and the capacities required for agency, entail the possession of sentience. (...) Thus on this account sentient beings possess agency and agents possess sentience. If this is correct, it will show that an Agency Account of moral status can offer a plausible defence of the moral status of all sentient beings, something that previous Agency Accounts have not succeeded in doing. What is more, this account could establish that all sentient animals are not just moral status holders per se, but that they are owed pro tanto obligations regarding continued existence and liberty, similar in kind, though not always in strength, to those owed to humans.

Animals who live in cities must coexist with us. They are, as a result, entitled to the conditions of their flourishing. This article argues that, as the boundaries of cities and urban areas expand, the boundaries of our conception of captivity should expand too. Urbanization can undermine animals’ freedoms, hence their ability to live good lives. I draw the implications of an account of “pervasive captivity” against the background of the Capabilities Approach. I construe captivity, including that of urban animals, (...) as affecting a range of animal capabilities, understood as freedoms, and I address some tensions within Nussbaum’s treatment of human-animal conflicts. Using the Capabilities Approach as a guide, I will attempt to motivate a convergence between habitat preservation in urbanized environments, urban design guided by justice, and the individual freedoms of animals.

Empirical studies of the social lives of non-human primates, cetaceans, and other social animals have prompted scientists and philosophers to debate the question of whether morality and moral cognition exists in non-human animals. Some researchers have argued that morality does exist in several animal species, others that these species may possess various evolutionary building blocks or precursors to morality, but not quite the genuine article, while some have argued that nothing remotely resembling morality can be found in any non-human (...) species. However, these different positions on animal morality generally appear to be motivated more by different conceptions of how the term “morality” is to be defined than by empirical disagreements about animal social behaviour and psychology. After delving deeper into the goals and methodologies of various of the protagonists, I argue that, despite appearances, there are actually two importantly distinct debates over animal morality going on, corresponding to two quite different ways of thinking about what it is to define “morality”, “moral cognition”, and associated notions. Several apparent skirmishes in the literature are thus cases of researchers simply talking past each other. I then focus on what I take to be the core debate over animal morality, which is concerned with understanding the nature and phylogenetic distribution of morality conceived as a psychological natural kind. I argue that this debate is in fact largely terminological and non-substantive. Finally, I reflect on how this core debate might best be re-framed. (shrink)

Definitions of animal welfare often invoke consciousness or sentience. Marian Stamp Dawkins has argued that to define animal welfare this way is a mistake. In Dawkins’s alternative view, an animal with good welfare is one that is healthy and “has what it wants.” The dispute highlights a source of strain on the concept of animal welfare: consciousness-involving definitions are better able to capture the normative significance of welfare, whereas consciousness-free definitions facilitate the validation of welfare indicators. (...) I reflect on how the field should respond to this strain, ultimately recommending against splitting the concept and in favor of consciousness-involving definitions. (shrink)

Do non-human animals have an interest in sociopolitical freedom? Cochrane has recently taken up this important yet largely neglected quest ion. He argues that animal freedom is not a relevant moral concern in itself, because animals have a merely instrumental but not an intrinsic interest in freedom (Cochrane 2009a, 2012). This paper will argue that even if animals have a merely instrumental interest in freedom, animal freedom should nonetheless be an important goal for our relationships with animals. Drawing (...) on recent work on the value of freedom, it will be argued that freedom is non-specifically instrumentally valuable. Accordingly, freedom is a means to other goods, but often it is not possible to identify those goods in advance or aim for them directly. Some of the reasons that make freedom non-specifically valuable for human relationships, it will be argued, also apply to relationships between humans and animals. Amongst other implications, it will be shown how this argument provides a response to those who fear that stricter animal protection policies might undermine people’s freedom: A concern for freedom actually requires stricter protection policies rather than speak against them.

Animal welfare has a long history of disregard. While in recent decades the study of animal welfare has become a scientific discipline of its own, the difficulty of measuring animal welfare can still be vastly underestimated. There are three primary theories, or perspectives, on animal welfare - biological functioning, natural living and affective state. These come with their own diverse methods of measurement, each providing a limited perspective on an aspect of welfare. This paper describes a (...) perspectival pluralist account of animal welfare, in which all three theoretical perspectives and their multiple measures are necessary to understand this complex phenomenon and provide a full picture of animal welfare. This in turn will offer us a better understanding of perspectivism and pluralism itself. (shrink)

Reportedly ever since Pythagoras, but possibly much earlier, humans have been concerned about the way non human animals (henceforward “animals” for convenience) should be treated. By late antiquity all main traditions with regard to this issue had already been established and consolidated, and were only slightly modified during the centuries that followed. Until the nineteenth century philosophers tended to focus primarily on the ontological status of animals, to wit on whether – and to what degree – animals are actually rational (...) beings; accordingly they allowed – or denied – them some kind of moral standing. This modus operandi was for the first time seriously questioned by Jeremy Bentham, who put the issue on a different track. If the question, as Bentham suggested, is not if animals can think or speak, but if they can suffer1, then it seems plausible that moral agents ought to abstain from inflicting unnecessary suffering on animals; in other words, humans might have at least one – even limited – moral duty towards animals. And if this, in turn, is true, then animals should arguably be allowed the commensurate moral right, namely the right not to be inflicted unnecessary pain. Then, if animals possess this right, they could probably possess others, as well. This is how grosso modo the issue of animal rights became a pivotal part of the discussion concerning animal ethics. Bentham himself, of course, wouldn’t have gone that far; to him even the idea of human rights sounded like “simple… rhetorical nonsense upon stilts”.2 It was mostly due to his views, however, that the debate was moved from the way things actually are to the way things should ideally be – thus merging into what, in my view, should always have been: one primarily concerning ethics.

_ Source: _Volume 48, Issue 1, pp 57 - 76 The aim of this article is to address the question of the anthropological difference by focusing on the intersubjective relation between the human and the animal in the context of a phenomenological analysis of violence. Following some Levinasian and Derridian insights, my goal is to analyze the structural differences between interspecific and intraspecific violence by asking how the generic phenomenon of violence is modalized across various levels: from human to (...) human, from human to animal, from animal to human, from animal to animal.

This Open Access book provides both a broad perspective and a focused examination of cow care as a subject of widespread ethical concern in India, and increasingly in other parts of the world. In the face of what has persisted as a highly charged political issue over cow protection in India, intellectual space must be made to bring the wealth of Indian traditional ethical discourse to bear on the realities of current human-animal relationships, particularly those of humans with cows.

This article brings animal protection theory to bear on Temple Grandin’s work, in her capacity both as a designer of slaughter facilities and as an advocate for omnivorism. Animal protection is a better term for what is often termed animal rights, given that many of the theories grouped under the animal rights label do not extend the concept of rights to animals. I outline the nature of Grandin’s system of humane slaughter as it pertains to cattle. (...) I then outline four arguments Grandin has made defending meat-eating. On a protection-based approach, I argue, Grandin’s system of slaughter is superior to its traditional counterpart. Grandin’s success as a designer of humane slaughterhouses however is not matched by any corresponding success in offering a moral defence of meat-eating. Despite, or perhaps because of, the popularity of her work, Grandin’s arguments for continuing to eat animals are noteworthy only in how disappointing and rudimentary they are. If we can thank Grandin for making a difference in the lives of millions of farm animals, her work can also be criticized for not engaging the moral status of animals with the depth and rigor that it deserves.

This chapter considers philosophical problems concerning non-human (and sometimes human) animals, including their metaphysical, physical, and moral status, their origin, what makes them alive, their functional organization, and the basis of their sensitive and cognitive capacities. I proceed by assuming what most of Descartes’s followers and interpreters have held: that Descartes proposed that animals lack sentience, feeling, and genuinely cognitive representations of things. (Some scholars interpret Descartes differently, denying that he excluded sentience, feeling, and representation from animals, and I consider (...) the evidence for these interpretations as well.) Given that Descartes denied any sort of soul to animals, his other philosophical commitments entailed that he must explain the vital and sensitive powers of non-human animals through purely material causes. Indeed, he welcomed this task, for he was engaged in the larger project of providing purely mechanistic explanations for all natural phenomena of the material world. Animal bodies form functional unities that are adapted to environmental circumstances. In his new physics, Descartes sought to discover or hypothesize material mechanisms that would explain the physiological and behavioral capacities of animals, including how they maintain themselves by seeking food and drink, reproduce themselves, and modify their behavior to fit current circumstances. Metaphysically, his new perspective raised the problem of accounting for the functional unity of the animal body considered as a purely material construction, devoid of an active, organizing power such as the sensitive soul. Descartes’s project becomes even more challenging if we ask whence come such mechanisms that are capable of performing the functions of living things. Officially, Descartes endorsed the accepted theological orthodoxy, that God designed and created the bodily mechanisms of humans and animals. However, in his natural philosophy he set himself the task of explaining the origin of animals as part of the natural development of the universe out of an original chaotic soup of material particles. Within this naturalistic perspective, he must explain how, through purely material processes, the functionally organized bodies of living things (plants and animals) could be produced from non-living matter. Without a designing creator, how do animal bodies arise that are capable of digesting food, growing, reproducing, and performing the behaviors needed to preserve life and health? (shrink)

Following recent arguments that cultural practices in wild animal populations have important conservation implications, we argue that recognizing captive animals as cultural has important welfare implications. Having a culture is of deep importance for cultural animals, wherever they live. Without understanding the cultural capacities of captive animals, we will be left with a deeply impoverished view of what they need to flourish. Best practices for welfare should therefore require concern for animals’ cultural needs, but the relationship between culture and (...) welfare is also extremely complex, requiring us to rethink standard assumptions about what constitutes and contributes to welfare.

Starting from the assumption that Kant allows for the possible existence of conscious sensory states in non-rational animals, I examine the textual and philosophical grounds for his acceptance of the possibility that such states are also 'objective'. I elucidate different senses of what might be meant in crediting a cognitive state as objective. I then put forward and defend an interpretation according to which the cognitive states of animals, though extremely limited on Kant's view, are nevertheless minimally objective.

Wild animal reproduction poses an important moral problem for animal rights theorists. Many wild animals give birth to large numbers of uncared-for offspring, and thus child mortality rates are far higher in nature than they are among human beings. In light of this reproductive strategy – traditionally referred to as the ‘r-strategy’ – does concern for the interests of wild animals require us to intervene in nature? In this paper, I argue that animal rights theorists should embrace (...) fallibility-constrained interventionism: the view that intervention in nature is desirable but should be constrained by our ignorance of the inner workings of ecosystems. Though authors sometimes assume that large-scale intervention requires turning nature into an enormous zoo, I suggest an alternative. With sufficient research, a new form of gene editing called CRISPR promises to one day give us the capacity to intervene without perpetually interfering with wild animals’ liberties. (shrink)

This paper is a summary of my book 'Wild Animal Ethics'.

Proponents of the utilitarian animal welfare argument (AWA) for veganism maintain that it is reasonable to expect that adopting a vegan diet will decrease animal suffering. In this paper I argue otherwise. I maintain that (i) there are plausible scenarios in which refraining from meat-consumption will not decrease animal suffering; (ii) the utilitarian AWA rests on a false dilemma; and (iii) there are no reasonable grounds for the expectation that adopting a vegan diet will decrease animal (...) suffering. The paper is divided into four sections. In the first, I set out the utilitarian AWA in its original form. I give some background and I distinguish it from other, related arguments. In the second, I discuss the causal impotence objection, a popular objection to the utilitarian AWA. I explain how the objection works by means of a conceptual distinction between consumers and producers. In the third, I explain how proponents of the utilitarian AWA respond to this objection. In particular, I set out in some detail what I call the expected utility response. In the fourth and final section, I use the three objections noted above to explain why I do not find this response convincing. (shrink)

The personal identity relation is of great interest to philosophers, who often consider fictional scenarios to test what features seem to make persons persist through time. But often real examples of neuroscientific interest also provide important tests of personal identity. One such example is the case of Phineas Gage – or at least the story often told about Phineas Gage. Many cite Gage’s story as example of severed personal identity; Phineas underwent such a tremendous change that Gage “survived as a (...) different man.” I discuss a recent empirical finding about judgments about this hypothetical. It is not just the magnitude of the change that affects identity judgment; it is also the negative direction of the change. I present an experiment suggesting that direction of change also affects neuroethical judgments. I conclude we should consider carefully the way in which improvements and deteriorations affect attributions of personal identity. This is particularly important since a number of the most crucial neuroethical decisions involve varieties of cognitive enhancements or deteriorations. (shrink)

This paper addresses two specific and related questions the Buddhist neuroethics program raises for our traditional understanding of Buddhist ethics: Does affective neuroscience supply enough evidence that contempla- tive practices such as compassion meditation can enhance normal cognitive functioning? Can such an account advance the philosophical debate concerning freedom and determinism in a profitable direction? In response to the first question, I argue that dispositions such as empathy and altruism can in effect be understood in terms of the mechanisms (...) that regulate affective cognition. In response to the second question, I claim that moral agency is a type of achievement that comes with learning the norms of ethical con- duct, which are not tractable by specifically neurobiological mechanisms and processes (though, once learned, such norms would have their neural cor- relates when enacted).

Animal rights activists are often accused of caring more about animals than about human beings. How, it is asked, can activists condemn the use of animals in biomedical research—research that improves human health and saves human lives? In this article, I argue that even if animal experimentation might eventually provide cures for many serious diseases, given the present state of the world, we are not justified supporting this research; rather, we ought to devote our limited resources to other (...) forms of humanitarian assistance.

This article establishes grounds on which attributions of information and encoding in animal signals are warranted. As common interest increases between evolutionary agents, the theoretical approach best suited to describing their interaction shifts from evolutionary game theory to communication theory, which warrants informational language. The take-home positive message is that in cooperative settings, signals can appropriately be described as transmitting encoded information, regardless of the cognitive powers of signalers. The canonical example is the honeybee waggle dance, which is discussed (...) extensively in the second and third sections. The take-home negative message is that signals are not always a consequence of coadaptation. The communication theory approach is just one end of a continuum explored more thoroughly by evolutionary game theory. The fourth and fifth sections explore this wider framework, as well as overturning some widely held misconceptions about information theory. (shrink)

In a recent study published in Scientific Reports, the researchers documented the first wild animal seen using a plant with known medicinal properties to heal a wound.

What can we infer from numerical cognition about mathematical realism? In this paper, I will consider one aspect of numerical cognition that has received little attention in the literature: the remarkable similarities of numerical cognitive capacities across many animal species. This Invariantism in Numerical Cognition (INC) indicates that mathematics and morality are disanalogous in an important respect: proto-moral beliefs differ substantially between animal species, whereas proto-mathematical beliefs (at least in the animals studied) seem to show more similarities. This (...) makes moral beliefs more susceptible to a contingency challenge from evolution compared to mathematical beliefs, and indicates that mathematical beliefs might be less vulnerable to evolutionary debunking arguments. I will then examine to what extent INC can be used to flesh out a positive case for mathematical realism. Finally, I will review two forms of mathematical realism that are promising in the light of the evolutionary evidence about numerical cognition, ante rem structuralism and Millean empiricism.

Merleau-Ponty suggests in his Nature lectures that myth provides the best way into thinking the relation of strange kinship between humanity and animality. He goes on to refigure Husserl’s paradigm of the two hands touching to extend beyond merely human-to-human relations, invoking in the process the myth of Narcissus. By carefully examining Merleau-Ponty’s late refiguration of that paradigm, alongside the revised conception of narcissism that it helps him to develop, we find that while human-animal empathy is made possible by (...) a ground of intercorporeal kinship, human-animal estrangement makes possible the emergence of an ethical relation to other animals, contingent upon the sublimation of animal desire. Holding human-animal kinship and estrangement in tension reveals a nascent ideal present implicitly in the early stages of childhood development: a vision of the possibility of interspecies harmony, rooted in the bodily reciprocity that drives the process of self-maturation.

How does consciousness vary across the animal kingdom? Are some animals ‘more conscious’ than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness. For each dimension, existing experiments that bear on it are reviewed and future experiments are suggested. By assessing a given species against each dimension, we can construct a consciousness profile (...) for that species. On this framework, there is no single scale along which species can be ranked as more or less conscious. Rather, each species has its own distinctive consciousness profile. (shrink)
