The Great Web of Being: Environmental Ethics without Value Hierarchy

Hierarchical views of the world such as the great chain of being have come under sustained critique in recent decades, and rightly so. They have justified not only the domination of non-human creatures but also the devaluation (via animalization/racialization) of many humans. The rejection of hierarchy and the great chain of being, however, does not require the rejection of the Christian Platonic theological vision upon which hierarchy is often based. In this paper, I argue that Christian Platonic theology has always been in tension with the great chain of being and is better suited to a non-hierarchical view of creaturely value. I then develop the ethical implications of this view in dialogue with both environmental and animal ethics and anti-racist and decolonial scholarship.

More than a simple fixed action pattern: Yawning in drills

In the last decade, increasing attention has been devoted to exploring some aspects of yawning in non-human animals. With their chin red mark, bony paranasal swellings, male large brains and long canines, drills (Mandrillus leucophaeus) offer a robust model for testing hypotheses on the phenomenon. We identified two yawn variants (covered, YCT and uncovered teeth, YUCT) which differ in terms of recruitment of muscular action units (AUs). We tested the effects of several variables (sex, dominance rank, context) on the duration of the yawn and the probability of YCT or YUCT occurrence. We found that males performed longer and more YUCT than females. These findings support the Brain Cooling Hypothesis suggesting that those species showing large brains tend to display larger and longer yawns. We also tested the State Changing Hypothesis predicting the presence of a temporal association of yawning and ongoing behavioral transitions. A sequential analysis revealed that after 30 s following a yawn, drills were significantly more likely to change their behavioral state. Through the observation of yawning, conspecifics might gain knowledge of impending state changes. Seeing other’s yawns increased the probability of a similar response in the observers, thus suggesting the presence of yawn contagion in drills. Although the dataset needs to be expanded, our findings indicate that yawning is variable in drills, it can be associated with subjects’ state changes, and the imminent shifts can be perceived/processed by conspecifics.Graphical

The Anvil, the Ascent, and Enoch

First Enoch, a pseudepigraphical work from the Second Temple period, contains visions of the natural and supernatural world that cause the visionary, Enoch, to understand anew the beyond-human world. Written during a time of environmental devastation, 1 Enoch can be a resource for helping today’s readers rewild our religious imaginations, our understanding of worship, and our relationship with nonhuman creation. This essay offers a reflection on how the Book of the Watchers in 1 Enoch and the author’s failed attempts to reach a mountain peak helped the author better understand the unseating of humanity as the center of creation as an experience of grace.

Feral ecologies of the human deep past: multispecies archaeology and palaeo‐synanthropy

AbstractThis article articulates recent advances in palaeo‐ecology with the goals and ambitions of multispecies archaeology. It centres the synanthropic nexus as a key context for the study of early human‐animal relationships and argues that its evolution yields important yet currently overlooked dynamics shaping the structure of the archaeological record. I first show how the dominant heuristic of wild versus domesticated nonhuman animals obfuscates the inherent variability and creativity of past animal agency. I then illustrate how such agency is caught up with human behaviour and ecosystem impacts from relatively early on in human history, navigating historically shifting configurations of autonomy and control. Drawing on deep‐historical examples of synanthropic niches co‐assembled by human foragers and nonhuman animals, I argue that such interspecies configurations require careful attention to concepts of liminality and ferality and challenge species‐level approaches. I finally highlight potential human behavioural, material, and cosmological consequences of the synanthropic nexus, including integrative foraging patterns and notions of the giving animal, which play an important role in many Indigenous and ethnographic forager societies and illustrate the value of attending to this nexus as a focus of comparative multispecies research.

Performing yoga postures in an environmental education course: The potential of creating pedagogical places of contemplation for the empowerment of ecological consciousness

The present study attempts to answer if yoga practice belongs to environmental education and how it can contribute to the development of ecological consciousness in the framework of a holistic pedagogical paradigm. Twenty-three post-graduate students participated in an environmental education activity based on performing yoga postures inspired by nonhuman creatures and entities. The participants reflected on their experiences by recording their ideas and feelings. The results of the survey revealed that the participants experienced embodied environmental learning, highlighted a healing dimension of the educational process, and experienced a connection with creatures and entities of nonhuman nature at different levels. Yoga philosophy and practice as a contemplative learning method deserve to be explored more widely in the field of environmental education, and especially regarding the development of ecological consciousness.

“The Natural World”: An Eco-Justice Case Study, 1972–1992

ABSTRACT This article explores the history of the United Methodist Social Principles as a case study, from their commissioning in 1968 and adoption in 1972 through several quadrennia of implementation, debate, and revision by General Conference sessions, in order to examine the eco-justice movement and the place of nonhuman animals in United Methodist polity. Focusing on the section of the Principles titled “The Natural World,” the author traces language related to concepts of the eco-justice movement, creation care, and nonhuman animals. Examining both proposed and adopted language at General Conferences, the author attends to which individuals and organizations, including caucus groups, advocated for changes related to “The Natural World” Social Principles. Exploring how eco-justice concerns become part of the social justice framework of The UMC over time, the article also examines how changes occur within the denomination, and who has influence within official structures.

The emerging role of glucagon-like peptide 1 in binge eating.

Binge eating is a central component of two clinical eating disorders: binge eating disorder and bulimia nervosa. However, the large treatment gap highlights the need to identify other strategies to decrease binge eating. Novel pharmacotherapies may be one such approach. Glucagon-like peptide-1 (GLP-1) is an intestinal and brain-derived neuroendocrine signal with a critical role in promoting glycemic control through its incretin effect. Additionally, the energy balance effects of GLP-1 are well-established; activation of the GLP-1 receptor (GLP-1R) reduces food intake and body weight. Aligned with these beneficial metabolic effects, there are GLP-1R agonists that are currently used for the treatment of diabetes and obesity. A growing body of literature suggests that GLP-1 may also play an important role in binge eating. Dysregulation of the endogenous GLP-1 system is associated with binge eating in non-human animal models, and GLP-1R agonists may be a promising approach to suppress the overconsumption that occurs during binge eating. Here, we briefly discuss the role of GLP-1 in normal energy intake and reward and then review the emerging evidence suggesting that disruptions to GLP-1 signaling are associated with binge eating. We also consider the potential utility of GLP-1-based pharmacotherapies for reducing binge eating behavior.

Human Brain Organoid Transplantation: Testing the Foundations of Animal Research Ethics

Alongside in vitro studies, researchers are increasingly exploring the transplantation of human brain organoids (HBOs) into non-human animals to study brain development, disease, and repair. This paper focuses on ethical issues raised by such transplantation studies. In particular, it investigates the possibility that they might yield enhanced brain function in recipient animals (especially non-human primates), thereby fundamentally altering their moral status. I assess the critique, raised by major voices in the bioethics and science communities, according to which such concerns are premature and misleading. I identify the assumptions underlying this skeptical critique, and mention some objections against them, followed by some possible replies. I proceed to argue that the skeptical position is ultimately implausible, because it presupposes an unreasonably high standard of full moral status. My argument appeals to David DeGrazia’s idea of a “borderline person”, and to the need for consistency with existing animal research regulations. I outline the practical implications of my view for the conduct of studies that might result in the development of full moral status in a transplanted animal. I also discuss some of the ethical implications of animal enhancement (particularly of rodents) below the threshold associated with full moral status. I conclude that far from being premature, further debate on these issues is urgently needed to help clarify the prospects that a neural chimera might attain full moral status in the foreseeable future, and the level of quality of life required to make it acceptable to knowingly create such a being via HBO transplantation.

"Ché Coco, ché Coco": An animal reading of Coco the parrot in Jean Rhys’s Wide Sargasso Sea

The various human characters of Jean Rhys’s novel Wide Sargasso Sea (1966) have attracted the attention of literary scholars from different perspectives. However, the novel’s nonhuman animal characters have previously been studied mainly as symbols for human actions and destinies. In this article, I problematise this type of anthropocentric approach from a Human-Animal Studies and a literary criticism perspective. I analyse Coco as a character of the novel and as a member of his own species. My analysis examines the nature of human-animal relationships, their representations in literature, and the binary oppositions inherent in them. Additionally, I critically evaluate the ways in which nonhuman animals are perceived and depicted in cultural representations. I argue that Rhys shows Coco as a parrot with species-typical behaviour and as a character with his own agency. Nevertheless, one should not disregard his symbolic functions, which draw attention to gendered colonial violence. Furthermore, the symbolic and linguistic violence in the novel forces the nonhuman animal into a position below the human animal and normalises violence towards nonhuman animals. The human-animal relationships in Wide Sargasso Sea vary from something akin to close companionship all the way to subjugation under the will of the more powerful.

Gentrification drives patterns of alpha and beta diversity in cities

While there is increasing recognition that social processes in cities like gentrification have ecological consequences, we lack nuanced understanding of the ways gentrification affects urban biodiversity. We analyzed a large camera trap dataset of mammals (>500 g) to evaluate how gentrification impacts species richness and community composition across 23 US cities. After controlling for the negative effect of impervious cover, gentrified parts of cities had the highest mammal species richness. Change in community composition was associated with gentrification in a few cities, which were mostly located along the West Coast. At the species level, roughly half (11 of 21 mammals) had higher occupancy in gentrified parts of a city, especially when impervious cover was low. Our results indicate that the impacts of gentrification extend to nonhuman animals, which provides further evidence that some aspects of nature in cities, such as wildlife, are chronically inaccessible to marginalized human populations.

A Bird's‐Eye View of Animals in the Law

The article develops an analytic account of nonhuman animals’ current legal status. Animals are often characterised as legal things and property, but this characterisation is both simplistic and, in some cases, incorrect. The article seeks to dispel a number of orthodoxies regarding the legal status of animals and offer a more nuanced and contextual account. The emphasis is on Western law, with a particular focus on European jurisdictions. The article approaches animal legal status in terms of two historical regimes: the Commodity Regime and the More‐than‐Commodity Regime. While treating animals as commodities has been the rule for millennia, the situation has recently become more multifaceted. For instance, the private law status of companion animals has shifted away from that of commodities. Furthermore, it is argued that some wild animals have stopped being legal things altogether as a result of EU wildlife law. The multifarious arguments are then synthesised in order to produce a bird's‐eye view of animals in the law.

”You don’t have the right to steal my life”: Exploring the harms of puppy farming on ex-breeding dogs

The last decade or so has witnessed a growing body of work within green criminology exploring forms of non-human animal abuse and harms involving companion animals. To date, however, comparably less attention has been paid to the puppy trade and the phenomena of commercial dog breeding facilities (or puppy mills/puppy farms). The aim of this article is to add to this literature by exploring the multiple harms of puppy farming, focusing on its impact on the breeding dogs themselves; specifically breeding bitches. Adopting a green criminological perspective and drawing on interviews with animal rescue staff, foster carers and those who have adopted ex-breeding dogs within the UK, the article explores the harms of puppy farming on their bodies and behaviours. Interviewees describe how ex-breeding dogs are physically worn out after a life of constant breeding and often suffer from a range of often serious medical issues. In addition, they were invariably emotionally shut down, exhibiting anxiety and phobic responses when confronted with new situations, people and sounds, as well as ones that recalled the conditions in which they were kept while in the puppy farm.

“The Poetry of a Dingo’s Bite”

Science fiction has an extensive history of attempting to breach the communication boundary between humans and nonhuman animals by giving nonhuman animals some semblance of human language, with many uplift stories having them speak near-perfect English, their minds being filtered through a human linguistic framework, partly or wholly erasing their voice. Building on the examination of nonhuman animal gestural communication in Brian Massumi’s What Animals Teach Us about Politics (2014), this paper analyses how two works, Ursula K. Le Guin’s “‘The Author of the Acacia Seeds’ and Other Extracts from the Journal of the Association of Therolinguistics” (1974) and Laura Jean McKay’s The Animals in That Country (2020) depict animal behavior in itself as being creative and language-like. Neither story offers a straightforward translation from nonhuman to human, each showing how human linguistic frameworks leave gaps for the untranslatable complexities in nonhuman animal gestures. This I suggest shows that further exploration of nonhuman animal communication in science fiction can allow us to move beyond ideas of human exceptionalism and logocentrism and can turn the hierarchical scale of communication into more of a spectrum with various communication types.

Rawlsian Anti-Capitalist Environmental Justice

In this paper, I examine John Rawls’ claim in the first edition of A Theory of Justice that Justice as Fairness cannot include considerations about the environment and non-human animals. The paper aims to resolve the tension in this statement, as the idea of a Rawlsian well-ordered society without concern for the rest of nature presents as a contradiction. Through a more charitable reading of Rawlsian theory that borrows from anti-capitalist and environmental justice frameworks, we can see how Rawlsian justice connects tightly to these issues. I conclude that the Rawlsian well-ordered society must be committed to anti-capitalist environmental justice.

After-Death Communications (ADCs) from Non-Human Animals: Parallels with Human ADCs

In an earlier study, Rupert Sheldrake, Pam Smart, and Michael Nahm reviewed accounts of end-of-life experiences (ELEs) involving non-human animals. They showed animal ELEs to be similar to human ELEs, suggesting common underlying processes. Here, we consider apparent after-death communications (ADCs) from non-human animals and compare them to accounts of ADCs from humans. We collected 442 accounts of animal ADCs from our own appeals and from reports in the literature. We found a close resemblance between ADCs from animals and from humans in the types of experience—dream visitations, a sense of presence, visual, auditory, tactile, and olfactory apparitions, and psychokinetic effects. As with human ADCs, the great majority of animal ADCs were reported to have occurred in the first hours or days after death, with a dramatic falling off over time. Moreover, our data show that people grieve their pets in much the same fashion as they grieve their human loved ones, suggesting that human bereavement studies would do well to take into account the animal data to which we draw attention. Doing so may help clarify issues regarding the fundamental nature of the experiences—determining whether they are best regarded as internal hallucinations, as living-agent-psi-mediated subjective or objective phenomena, or as actual contacts with the deceased—which in turn carries implications not only for academic studies of bereavement but for clinical practice with the bereaved.

Leisure Ex Machina: The Leisure Lives of Digital Minds

Humans may soon succeed in the creation of sentient artificial intelligence (SAI) that experiences human-like consciousness. Such SAI would have a claim to the same rights and moral considerations afforded to biological humans, including a right to leisure. Particular to this special issue, I explore the implications of such a development from the context of leisure studies; specifically, I apply utilitarian moral theory and the concept of a “utility monster,” as an analytical framework to consider the potential for SAI to degrade the wellbeing of humans and non-human animals through their leisure experiences. Throughout this essay, my overarching goal is to provide a thought provoking argument that serves as the context for fruitful reflection and discussion in the field of leisure studies. Due to their potentially superhuman efficiency in deriving benefits (“utility”) from experiences, SAI may become a “utility monster,” or a being with superior moral claim to scarce resources. As SAI will (a) likely be “human-like,” and (b) exist independent of the physiological needs/limits inherent to biological humans, it is likely that a large proportion of the experiences chosen by SAI would be categorizable as leisure. Following a utilitarian logic that the only morally acceptable action is the one that raises net utility by the greatest amount, other beings would be morally compelled to transfer all available resources to satisfy the leisure preferences of the SAI utility monster. I examine the implications of this moral quandary for leisure studies and wider society, and discuss three potential paths forward: total transfer of resources to a leisure-focused SAI utility monster; strict limits on the development of SAI; and a middle path where the interests of SAI and humans align. Although the topic of artificial intelligence is increasingly relevant in discussions within our broader society, and specific to the field of leisure studies, to date that conversation has largely focused on how technological advances in artificial intelligence will impact humans, and how that technology can be used in an ethical fashion; this essay refocuses the conversation to the implications for a potential SAI that may look and feel very much like we do.

Variation in the mu-opioid receptor gene (OPRM1) moderates the influence of maternal sensitivity on child attachment

The endogenous opioid system is thought to play an important role in mother-infant attachment. In infant rhesus macaques, variation in the μ-opioid receptor gene (OPRM1) is related to differences in attachment behavior that emerges following repeated separation from the mother; specifically, infants carrying at least one copy of the minor G allele of the OPRM1 C77G polymorphism show heightened and more persistent separation distress, as well as a pattern of increased contact-seeking behavior directed towards the mother during reunions (at the expense of affiliation with other group members). Research in adult humans has also linked the minor G allele of the analogous OPRM1 A118G polymorphism with greater interpersonal sensitivity. Adopting an interactionist approach, we examined whether OPRM1 A118G genotype and maternal (in)sensitivity are associated with child attachment style, predicting that children carrying the G allele may be more likely to develop an ambivalent attachment pattern in response to less sensitive maternal care. The sample consisted of 191 mothers participating with their children (n = 223) in the Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN) project, a community-based, birth cohort study of Canadian mothers and their children assessed longitudinally across the child’s development. Maternal sensitivity was coded from at-home mother-child interactions videotaped when the child was 18 months of age. Child attachment was assessed at 36 months using the Strange Situation paradigm. As predicted, G allele carriers, but not AA homozygotes, showed increasing odds of being classified as ambivalently attached with decreasing levels of maternal sensitivity. Paralleling earlier non-human animal research, this work provides support for the theory that endogenous opioids contribute to the expression of attachment behaviors in humans.

Confronting the bias towards animal experimentation (animal methods bias)

Laws and policies are in place around the world to promote the replacement and reduction of nonhuman animals in science. These principles are rooted not just in ethical considerations for animals, but also in scientific considerations regarding the limitations of using nonhuman animals to model human biology, health, and disease. New nonanimal research approaches that use human biology, cells, and data to mimic complex human physiological states and therapeutic responses have become increasingly effective and accessible, replacing the use of animals in several applications, and becoming a crucial tool for biomedical research and drug development. Despite many advantages, acceptance of these new nonanimal methods has been slow, and barriers to their broader uptake remain. One such barrier is animal methods bias, the preference for animal-based methods where they are not necessary or where animal-free methods are suitable. This bias can impact research assessments and can discourage researchers from using novel nonanimal approaches. This article provides an introductory overview of animal methods bias for the general public, reviewing evidence, exploring consequences, and discussing ongoing mitigation efforts aimed at reducing barriers in the shift away from animal use in biomedical research and testing.

Using isochrony, but not meter, to discriminate rhythmic sequences in rats (Rattus norvegicus).

Meter induction is a key process for rhythm perception. However, while some nonhuman animals readily detect temporal regularities and perceive beats in auditory sequences, there is no consistent evidence that they extract metrical structures. In the present experiment, we familiarized rats (Rattus norvegicus) to auditory rhythmic sequences that evoked a duple or a triple meter. We then tested their recognition of these familiar sequences when pitted against novel sequences that evoked no meter (isotonic), evoked a different meter (either duple or triple), or were nonmetrical (nonisochronous). The animals only discriminated isochronous from nonisochronous sequences. However, we found no evidence for meter induction, as the animals did not discriminate familiar from isotonic sequences or from sequences with a different meter. The findings suggest that, under a familiarization paradigm, the natural tendency of the animals is to focus on temporal rather than melodic changes to recognize rhythmic sequences.

Charles Darwin: towards a bio-religious and colonial genealogy of evolutionary being

ABSTRACT While studies have examined Charles Darwin's wide social and political impact, they have not adequately centred the combined influence of colonial systems of human differentiation and religion within them. To address this, I draw from Sylvia Wynter's critique concerning how religious and colonial discourses contribute to the shifting development of Man within the Western tradition. Specifically, I explore how Darwin focused his evolutionary gaze towards one of the unique foundations of what it meant to be human in his time: religion. Tracing the entangled religious and colonial filiations of Darwin's thought, I show that he established an evolutionary link between human and non-human animals by proposing both Indigenous peoples and dogs held superstitious beliefs. To illustrate this, I show that Darwin transposed Victorian anthropological conceptions of religion - as a quantifiable object of knowledge corresponding to the intellect and associated with phrenology, dream theory and the apparitional soul - into a bio-religious conception of evolution. Furthermore, I argue that Darwin's bio-evolutionism assumes Christianity is most closely associated with abstract reason. Finally, analyzing the role of race in Darwin's thought, I suggest that theology is not what was before modern scientific bio-evolutionary conceptions of race, but at its very core.
