Brain Complexity, Sentience And Welfare, Donald M. Broom

Animal Sentience

Neither sentience nor moral standing is confined to animals with large or human-like brains. Invertebrates deserve moral consideration. Definition of terms clarifies the relationship between sentience and welfare. All animals have welfare but humans give more protection to sentient animals. Humans should be less human-centred.

Invertebrate Cognition, Sentience And Biology, Georges Chapouthier

Animal Sentience

All animal species have adapted for survival and no species is superior overall. For cognitive capacities and sentience, invertebrates such as the octopus, although quite unlike vertebrates, can achieve similar performance levels. So can other invertebrates with small brains; hence they too, as sentient beings, deserve moral consideration from humans. How are we to identify these species? Only though a detailed analysis of their behavior. The decision, which is a moral judgment, depends on biological knowledge that still needs to be acquired.

Convergent Evolution Of Sentience?, Culum Brown Prof.

Animal Sentience

Mikhalevich & Powell make a compelling case that some invertebrates may be sentient and that our moral obligations in the context of welfare should hence extend to them. Although the case is similar to that made for fishes, there is one obvious difference in that examples of invertebrate sentience probably arose independently from vertebrate sentience. We have unequivocal proof that complex cognition arose multiple times over evolutionary history. Given that cognition is our best tool for indirectly quantifying sentience, it seems highly likely that this multiple polygenesis may also have occurred for sentience. In acknowledging this, we must accept that …

Minds, Morality And Midgies, Brian Key, Deborah Brown

Animal Sentience

Mikhalevich & Powell argue that the exclusion of the vast majority of arthropods from moral standing is unwarranted, particularly given the purported evidence for cognition and sentience in these organisms. The implied association between consciousness and moral standing is questionable and their assumption that rich forms of cognition and flexible behavior are dependent on phenomenal consciousness needs to be reconsidered in light of current neuroscientific evidence. We conclude by proposing a neural algorithmic approach for deciphering whether organisms are capable of subjective experience.

Martin Luther King Jr. And Ernest Everett Just - On Evolution Of Ethical Behavior, Theodore Walker

Perkins Faculty Research and Special Events

Rev. Martin Luther King Jr. prescribed an evolutionary advance in ethical behavior: the total “abolition of poverty” and the abolition of war throughout “the world house.” Cell biologist Ernest Everett Just advanced the idea that human ethical behavior evolved from cellular origins.

Also, astrobiologists Chandra Wickramasinghe and Sir Fred Hoyle advanced the idea of cosmic biology, including stellar evolution and cosmic evolution. From cells to humans to stars and cosmology, evolutionary natural science converges with natural theology.

The Bioethical Significance Of “The Origin Of Man’S Ethical Behavior” (October 1941, Unpublished) By Ernest Everett Just And Hedwig Anna Schnetzler Just, Theodore Walker Jr.

Journal of the South Carolina Academy of Science

Abstract –

E. E. Just (1883-1941) is an acknowledged “pioneer” in cell biology, and he is perhaps the pioneer in study of egg cell fertilization. Here we discover that Just also made pioneering contributions to general biology and evolutionary bioethics.

Within Just’s published contributions to observational cell biology, there are substantial fragments of his theory of ethical behavior, a theory with roots in cell biology. In addition to such previously available fragments, Just’s fully developed theory is now available. This recently discovered unpublished book-length manuscript argues for the biological origins of ethical behavior (evolving from cells to humans, within a …

Asian Elephant Rescue, Rehabilitation And Rewilding, Liv Baker, Rebecca Winkler

Animal Sentience

Thailand has fewer than 10,000 elephants left. More of them are living in captivity to serve the tourist industry under grim conditions than are living free in what is left of their wild habitat. Conservation efforts need to be focused on all surviving members of the species, captive and free, but they need to take into account the inextricable entanglement of human and nonhuman animal lives in Thailand today. There is an opportunity for rescuing, rehabilitating and reintroducing captive elephants to the wild with the help of the traditional expertise of a mahout culture that has been elephant-keeping for centuries. …

Anthropology And Conservation, Nicolas Lainé

Animal Sentience

Baker & Winkler make a welcome contribution to elephant conservation in Thailand in advocating a role for joint human/elephant labor and local expertise in rewilding. Their argument would benefit, however, if it drew more upon the local ethnographic evidence. Ethnocentric notions such as “welfare” and “wellbeing” may not fit into the local perception of pachyderms.

Rewilding And Domestication: Clarifying Terminology, Catia Correia-Caeiro

Animal Sentience

Baker & Winkler (B&W) describe the state of Asian elephant conservation, raising unique issues, and proposing a direction based on rewilding. The long history and socio-biology of elephants and humans has some parallels with the domestication of dogs (and other species). However, markers of domestication seem absent from elephants. The proper use of terms such as “wild” and “domestic” is crucial in defining the best conservation strategies, and, more important, in attending to the welfare needs of individuals, which can differ between wild and domestic animals. B&W’s target article represents an important starting point for discussion around elephant conservation, but …

Global Risks Of Intensive Animal Farming And The Wildlife Trade, Deborah Cao

Animal Sentience

This commentary discusses two issues highlighted by Wiebers & Feigin in the context of the current and future global health crisis: the wildlife trade and factory farming. Both are instances of globalized animal cruelty – in China as well as worldwide -- that require global solutions for the well-being of both humans and nonhumans.

One Planet, One Health, Michael W. Fox

Animal Sentience

We have to reduce our collective exploitation and consumption of animals. That is what is bringing on pandemics and other zoonotic diseases, accelerating climate change, destroying biodiversity, and causing untold amounts of animal suffering.

Cultured Meat Could Prevent The Next Pandemic, Jonathan Anomaly

Animal Sentience

Wiebers & Feigin identify intensive agriculture and trade in exotic animals as the main sources of novel zoonotic viral infections. They recommend a transition away from meat. I would add that we would do well to invest in the mass production of cultured meat, derived from stem cells, as a radical alternative to animal agriculture.

Innovation In Meat Production: A Problem And An Opportunity, Christopher J. Bryant

Animal Sentience

Innovation in meat production has enabled modern humans to inflict far greater harm on animals, the environment, and public health than was possible just a few decades ago. Wiebers & Feigin aptly express the urgency with which these issues must be addressed. Those advocating for animals on moral grounds face resistance from omnivores citing taste, price and convenience. Further innovation in meat production (plant-based and cultured meat) will enable us to preserve the experience of eating meat whilst phasing out the many problems caused by industrial animal farming.

Harm, Earth Jurisprudence And Human/Nonhuman Relationships, Tanya Wyatt

Animal Sentience

To prevent the next pandemic and to protect the environment and non-human animals, there needs to be a clear definition of harm and a legal system grounded in Earth Jurisprudence. Drawing on evolutionary principles to redefine harm and to radically alter the legal system to be Earth-centred will help ensure that harmful actions like certain wildlife trade, wildlife trafficking, and intensive farming do not threaten the survival of any life.

Covid-19, Evolution, Brains And Psychology, Frederick Toates

Animal Sentience

Attention needs to be directed to the processes that control behavior in humans and the adaptive problems that they solved in our early evolutionary environment. The evolutionary mismatch between the current environment and the human brain can yield important insights into the problems that beset us in the context of environmental degradation and nonhuman animal welfare.

Re-Engage With The World For Global Health And Animal Welfare, Bradley J. Bergstrom

Animal Sentience

Wiebers & Feigin (2020) make a strong argument for measures that would limit future zoonoses, such as the COVID-19 pandemic, by closing live-animal markets, changing our habits of food consumption and production, and reducing habitat destruction. These would help human health, animal welfare, and conservation of at-risk wildlife all at the same time. China’s command-and-control government can accomplish some of these things by edict, but slower-to-act western democracies play a surprisingly large role in these global problems by the power of their consumerism, including the illicit wildlife trade. We citizens need to insist that our government use all of its …

Thinking Longer, Looking Deeper, Ronnie Z. Hawkins

Animal Sentience

We need to situate the present crisis within the larger context of what we humans have done to the nonhuman forms of life with which we evolved, taking a longer view of our own evolutionary origins and a deeper look at what might be a more appropriate role for our species to play within the Biosphere.

Bridging The Empathy Gap For Invertebrates, John M. Marzluff

Animal Sentience

The actions of sentient vertebrates command our attention and inform our morality. Mikhalevich & Powell (2020) (M&P) argue that similar activities in a wide range of invertebrates with central nervous systems should do likewise. However, humans most readily empathize with creatures we recognize as similar in behavior, physiology, or appearance to ourselves. Helping humanity overcome this bias is a significant challenge for those who study invertebrates. Until this empathy gap is bridged, I believe few people and the policies they craft will afford invertebrates the moral standing that M&P argue they deserve. Therefore, I suggest those interested in raising appreciation …

Affective Sentience And Moral Protection, Russell Powell, Irina Mikhalevich

Animal Sentience

We have structured our response according to five questions arising from the commentaries: (i) What is sentience? (ii) Is sentience a necessary or sufficient condition for moral standing? (iii) What methods should guide comparative cognitive research in general, and specifically in studying invertebrates? (iv) How should we balance scientific uncertainty and moral risk? (v) What practical strategies can help reduce biases and morally dismissive attitudes toward invertebrates?

Improving Invertebrate Welfare, Heather Browning, Walter Veit

Animal Sentience

Mikhalevich & Powell (2020) argue that it is wrong, both scientifically and morally, to dismiss the evidence for sentience in invertebrates. They do not offer any examples, however, of how their welfare should be considered or improved. We draw on animal welfare science to suggest some ways that would not be excessively demanding.

Sentience In Evolutionary Context, Jon Mallatt, Todd E. Feinberg

Animal Sentience

We appreciate the goals of Mikhalevich & Powell (M&P) and largely agree with their conclusions but we differ on some of their definitions and terms. Affects (emotional feelings) should be part of sentience. Although the evidence presented for insect sentience is strong, we list some of the counterevidence that should be considered. Our own research supports M&P’s choice of arthropods, cephalopods, and vertebrates as the only sentient organisms with moral status.

Relationship Between Cognition And Moral Status Needs Overhaul, Carrie Figdor

Animal Sentience

I commend Mikhalevich & Powell for extending the discussion of cognition and its relation to moral status with their well researched and argued target article on invertebrate cognition. I have two small criticisms: that the scala naturae still retains its appeal to some in biology as well as psychology, and that drawing the line at invertebrates requires a bit more defense given the larger comparative cognitive-scientific context.

Insect Sentience And The Rise Of A New Inclusive Ethics, David Baracchi, Luigi Baciadonna

Animal Sentience

Welfare protections for vertebrates are grounded in the belief that vertebrates are sentient and capable of feeling whereas invertebrates are not. We agree with Mikhalevich & Powell that the exclusion of small-brained invertebrates from bioethics is not warranted by the current state of the scientific evidence. The choice to promote protection for certain invertebrates should be based on the Animal Sentience Precautionary Principle (ASPP). This principle should not prevent us from conducting experimental research with non-human animals to advance knowledge. However, we believe that it is important to outline practical guidelines to manage the wellbeing of invertebrates, while accumulating further …

Appealing To Human Intuitions To Reduce Animal Abuse, Yzar S. Wehbe, Todd K. Shackelford

Animal Sentience

Social scientists may be able to find ways to positively affect people’s evolved moral compasses, thereby doing the planet and its inhabitants a great kindness. They could help to shape a constituency that is increasingly opposed to animal abuse in its largest-scale manifestations, factory farming and wet markets. This would, in turn, motivate people to elect ethical leaders who view inaction with regard to animal abuse as a serious moral and medical mistake, if only indirectly due to factory farming’s exacerbation of the threats zoonoses pose to humans.

Pandemic Leadership Failures And Public Health, Gidon Eshel

Animal Sentience

In a plainly worded target article whose sagacity and import can hardly be overstated, Wiebers & Feigin place the recent COVID-19 crisis in historic perspective. They warn us that unless we make sweeping changes the next pandemics are all but preordained. They offer a blueprint for dramatically lowering the likelihood of future pandemics.

Animal Welfare Science And “A Life Worth Living” For Wild And Captive Elephants, Lindsay R. Mehrkam, Otto Fad

Animal Sentience

Baker & Winkler (2020) propose restoring elephants to a state of “wildness” and a “life worth living” by reintroducing captive elephants to the hands of indigenous mahout cultures and practices. To evaluate this proposal, we must define operationally a number of critical concepts in a species-centric, individualistic way, avoiding human-centric opinions and romanticized notions of the wild. Animal welfare science can help create greater synergy between ex-situ zoological institutions and in-situ elephant conservation, and welfare efforts that respect and value the cultures of both species.

Compassionate Conservation And Elephant Personhood, Arian D. Wallach, Sujeewa Jasinghe, Sudarshani Fernando, Jessica Bell Rizzolo

Animal Sentience

Baker and Winkler (2020) advocate a rehabilitation program that would end the oppression of elephants — not by severing human-elephant relations, but by enabling human-bonded elephants to live a full life. We consider this program within a compassionate conservation framework, which recognises all sentient beings as persons. From this vantage point, we gaze further into the future to ask what direction just human-elephant relations could take: What could emerge from a human-elephant relation once elephants are no longer enslaved and requiring rescue? We envisage a future — beyond captivity and rewilding — of elephant sovereignty.

Future Of Thailand's Captive Elephants, Antoinette Van De Water, Michelle Henley, Lucy Bates, Rob Slotow

Animal Sentience

Removal from natural habitat and commodification as private property compromise elephants’ broader societal value. Although we support Baker & Winkler’s (2020) plea for a new community-based rewilding conservation model focused on mahout culture, we recommend an expanded co-management approach to complement and enhance the regional elephant conservation strategy with additional local community stakeholders and the potential to extend across international borders into suitable elephant habitat. Holistic co-management approaches improve human wellbeing and social cohesion, as well as elephant wellbeing, thereby better securing long-term survival of Asian elephants, environmental justice, and overall sustainability.

Whenever Possible, Treat The Cause: Shut Down The Flu Factories, Michael Greger

Animal Sentience

Over the last few decades -- and at a historically unprecedented rate -- hundreds of human pathogens have emerged, mostly from animals. The United Nations’ “Preventing the Next Pandemic” report blames increasing demand for animal protein and unsustainable agricultural intensification as two key drivers of the emergence of zoonotic threats. Animal agribusiness has become a viral disease incubator, but there is a clear path towards preventing the next pandemic as well as protecting planetary health: to reform the practice of raising domestic animals for food and to adopt eating habits that not only protect our health, but address …

The Necessity Of Human Attitude Change And Methods Of Avoiding Pandemics, Donald M. Broom

Animal Sentience

Humans share their biology with other animals and in each of their actions should consider the consequences for all life. A series of measures can be taken by governments and individuals that would minimise inter-specific transfer of pathogens from wildlife and reduce the development of antimicrobial resistance.
