The Octopus: A Beautiful (But Disorganized) “Mind”, Jon Mallatt Jan 2019

The Octopus: A Beautiful (But Disorganized) “Mind”, Jon Mallatt

Animal Sentience

Mather (2019) presents convincing evidence that octopuses have minds, but in the first 85% of the target article, the evidence does not come through very clearly because it is hidden by other information and by problems with the paper’s organization. I propose ways to build a tighter argument in the author’s Response to the Commentaries.


Cephalopod Molluscs, Causal Models, And Curious Minds, Andrew W. Corcoran Jan 2019

Cephalopod Molluscs, Causal Models, And Curious Minds, Andrew W. Corcoran

Animal Sentience

Mather (2019) presents a compelling case in favour of octopus mind. Surveying an impressive array of empirical literature, she identifies the creature’s playful, inquisitive behaviour as emblematic of a distinctively mental form of agency. I offer an alternative perspective in which curiosity and play are construed as constitutive processes in the emergence of the (predictive) mind.


Are Our Ideas About Octopus Life Too Anthropomorphic To Help?, Kenneth J. Aitken Jan 2019

Are Our Ideas About Octopus Life Too Anthropomorphic To Help?, Kenneth J. Aitken

Animal Sentience

Our understanding of the evolution and ontogeny of the octopus and its behavioral repertoire in its natural habitat remains rudimentary at best. There are many parallels, but also just as many differences from our models of human biology and ontogeny, making anthropocentric generalizations of limited use in explanation.


Octopus Minds Must Lead To Octopus Ethics, Barbara J. King, Lori Marino Jan 2019

Octopus Minds Must Lead To Octopus Ethics, Barbara J. King, Lori Marino

Animal Sentience

Mather argues convincingly for the existence of minds in octopuses based largely on laboratory experiments. Many of these experiments are highly invasive and involve mutilation and death. Moreover, octopuses are now being hailed as a “new model” for biological research and are being enthusiastically bred in captivity, both for research and for food. We argue that the compelling evidence for mind in octopuses must be accompanied by intense scrutiny of the ethics that shape how we treat them and that the intrinsic value of their individual lives must be recognized.


Keeping Hold Of Nurse, Andrew Packard Jan 2019

Keeping Hold Of Nurse, Andrew Packard

Animal Sentience

Mather draws from a lifetime devoted to studying individual octopuses in the wild and in aquaria to combine a natural history account of their actions with an argument from design adopted from second-, often third-hand sources. The 'distributed' [decentralised] nervous system said to contrast with that of vertebrates – a premise largely accepted by Mather’s commentators so far – does not reflect the original literature on motor control, nor the facts of comparative anatomy, functional morphology and morphogenesis. Ontogeny is absent. With the help of some old or little-known illustrations from my own participant-observer experimental investigations, I will try here …


Octopus Sentience: Three Criteria, Alix Noël-Guéry Jan 2019

Octopus Sentience: Three Criteria, Alix Noël-Guéry

Animal Sentience

The first question to ask is whether octopuses are sentient, so that, if so, they can be protected. Three consensual criteria to evaluate animal sentience can be applied to the octopus. Octopuses meet all three of them.


Intelligence, Complexity, And Individuality In Sheep, Lori Marino, Debra Merskin Jan 2019

Intelligence, Complexity, And Individuality In Sheep, Lori Marino, Debra Merskin

Animal Sentience

Domestic sheep (Ovis aries) are among the earliest animals domesticated for human use. They are consumed worldwide as mutton, hogget, and lamb, kept as wool and milk producers, and used extensively in scientific research. The popular stereotype is that sheep are docile, passive, unintelligent, and timid, but a review of the research on their behavior, affect, cognition, and personality reveals that they are complex, individualistic, and social.


Is Knowing Enough To Change Human Attitudes And Actions?, Liv Baker Jan 2019

Is Knowing Enough To Change Human Attitudes And Actions?, Liv Baker

Animal Sentience

Marino & Merskin present evidence on key aspects of cognition, such as theory of mind, learning, emotional valence, and sociality, to make a convincing argument that sheep are due consideration as individual sentient beings. With this information, what will it take to produce a real, meaningful shift in our attitudes and actions towards other animals, including a species as disadvantaged as sheep? What else do we need to know?


Reflections On Sheep Rearing, Joyce D'Silva Jan 2019

Reflections On Sheep Rearing, Joyce D'Silva

Animal Sentience

Sheep rearing has an incredibly long history. Sometimes this alone can give credibility and status to a human practice. In the twenty-first century, it may be time to reassess our treatment of sheep and their place in nature. “Just because we’ve always done it” no longer has validity by itself. There are many other human practices which used to be accepted widely in certain societies and which we now may find abhorrent. With sheep intelligence now rightly regarded as an acceptable area of research within the academic community, it is a good time to reflect on our treatment of these …


Sacrificial Lambs, Clive Phillips Jan 2019

Sacrificial Lambs, Clive Phillips

Animal Sentience

Sheep evolved from the mouflon as mountain animals, able to escape predation by leaping between rock ledges. Their defense was their agility. Humans brought them to the plains, where the agility was less useful, but their lack of aggression, speed or weaponry against predators made them a prime target to become one of man’s meat providers. A perfect animal in many ways, with extraordinary perceptive powers and some remarkable cognitive skills, they are often treated with complete disregard for their welfare. Yet sheep themselves won’t tell us this, for a sheep that alerted others to its weakness really would be …


Far More To Sheep Than Meets The Casual Eye, Bernard Rollin Jan 2019

Far More To Sheep Than Meets The Casual Eye, Bernard Rollin

Animal Sentience

Marino & Merskin’s survey of the cognitive and social capacities of sheep is an eye-opener about the individuality and emotionality of this most maligned of all farm animals. My own eyes had already been opened by an adopted orphaned lamb, so much more like a dog as a companion animal than the mindless robot I had been conditioned to expect. I am morally certain that Marino & Merskin’s survey will have a similar effect on readers open to changing their minds.


Sentient Animals Do Not Just Live In The Present, John Webster Jan 2019

Sentient Animals Do Not Just Live In The Present, John Webster

Animal Sentience

Sheep are particularly well-equipped with the cognitive and emotional skills appropriate to their phenotype and natural environment. These include spatial memory, the benefits of safety in numbers, and the ability to recognise special individuals in large flocks by sight and by sound. Marino & Merskin’s target article reviews convincing evidence on whether sheep are more or less clever than other mammalian species. Sheep are very good at being sheep. But sentient animals do not just live in the present. Their emotional state is not simply dictated by events of the moment. If they learn, they can cope; if not, they …


Sheep In Aesop’S And Phaedrus’S Fables, Matteo Colombo, Chiara Raucea Jan 2019

Sheep In Aesop’S And Phaedrus’S Fables, Matteo Colombo, Chiara Raucea

Animal Sentience

Sheep feature in various animal fables. Marino & Merskin suggest that “we” view sheep as “docile, passive, unintelligent, and timid,” but animal fables do not support this view. In Aesop’s and Phaedrus’s fables, sheep are a primary target of injustice; but they are not passive targets. Sheep endure injustice actively and honestly. They are intelligent, aware and outspoken about their own condition.


Why Are Sheep Sheepish? How Perception Affects Animal Stereotyping, Robert G. Franklin Jr. Jan 2019

Why Are Sheep Sheepish? How Perception Affects Animal Stereotyping, Robert G. Franklin Jr.

Animal Sentience

Marino & Merskin present compelling evidence that many stereotypes of sheep are incorrect. One factor that may play an important role in animal stereotyping is the physical appearance of animals, which can directly lead to stereotyping through automatic mental processes. Sheep have a round and babyish appearance that directly evokes judgments of warmth and docility. Depictions of sheep in art, and especially cartoons, reinforce this stereotype.


Debunking Human Prejudice And Blindness, Peter J. Li Jan 2019

Debunking Human Prejudice And Blindness, Peter J. Li

Animal Sentience

Human prejudice and blindness to animal suffering are shocking. Despite their differences in culture, politics, and religious beliefs, humans have one thing in common. They see nonhuman animals as inferior and have since time immemorial assumed a dominant position in an asymmetrical human-animal relationship. When it comes to human-animal relations, there is no “clash of civilizations.” Human prejudice and blindness are predicated on “common sense assumptions” about the natural world and nonhuman animals in particular. Marino & Merskin’s review is part of the growing effort to debunk the assumptions that have shaped human actions so as to end the injustice …


Sheep Complexity Outside The Laboratory, Cheryl Abbate Jan 2019

Sheep Complexity Outside The Laboratory, Cheryl Abbate

Animal Sentience

Marino & Merskin’s review shows that sheep are intelligent and highly social but their methodology has some shortcomings. I describe five problems with reviewing only the academic and scientific literature and suggest how one might provide an even more compelling case for the complexity of sheep minds.


Cognition, Emotion, Personality And The Conservation And Management Of Wild Ungulates, Rob Found Jan 2019

Cognition, Emotion, Personality And The Conservation And Management Of Wild Ungulates, Rob Found

Animal Sentience

Increasing public understanding of the complexity of wild ungulates can improve animal welfare and advance global conservation efforts of these keystone species. Unfortunately, shaping public opinion on wild species is challenging because personal experience with wildlife is declining, popular education is still biased towards the predator instead of the prey, and scientific research is more difficult to conduct on wild ungulates compared to those on farms, in zoos, or otherwise in captivity. Nevertheless, studies of cognition, individuality, and intelligence of wild ungulates are increasing. I briefly highlight some major results from my own work on complexity in wild elk, illustrating …


What Every Shepherd Knows, Marthe Kiley-Worthington Jan 2019

What Every Shepherd Knows, Marthe Kiley-Worthington

Animal Sentience

The findings of the research reviewed by Marino & Merskin have been common knowledge to shepherds for millennia. Many of them are also evolutionary necessities for all mammals, especially social ones.


The Importance Of Research Applicability, Krista Mclennan Jan 2019

The Importance Of Research Applicability, Krista Mclennan

Animal Sentience

Marino & Merskin’s (2019) review contains key information about the complexity of sheep and their intelligence level, but lacks practical application. The key to making any long-term changes to sheep welfare at an industry level is by generating research that is practically relevant to the sector. The practical application of research should be considered at the design stage and in consultation with producers. Additionally, thought needs to be given to how the practical application of the research will be transferred to those people directly involved in animal care (e.g., producers, stockpersons, etc.). Focusing on the practical relevance and application of …


Cognitive Dissonance About Sheep Cognition And Consumption, Catia Correia Caeiro Jan 2019

Cognitive Dissonance About Sheep Cognition And Consumption, Catia Correia Caeiro

Animal Sentience

Sheep are perceived as mere resources under the massive demand of the food and wool industry. Evidence that sheep cognition is comparable to that of other species may inspire reflection on sheep consumption. Dogs may be a promising comparison species.


Social Cognition In Sheep: Welfare Implications, Keith M. Kendrick Jan 2019

Social Cognition In Sheep: Welfare Implications, Keith M. Kendrick

Animal Sentience

More research has been carried out on social cognition in sheep than in other farm animal species. Although this has often been featured widely in the media, there is still limited public awareness of it. Marino & Merskin’s review is therefore both important and timely. In my commentary, I focus primarily on what has been established about the complexity of sheep social cognition, at the level of both brain and behavior, and on some of these findings for sheep welfare.


Animal Sentience Is Not Enough To Motivate Conservation, Irene M. Pepperberg Jan 2019

Animal Sentience Is Not Enough To Motivate Conservation, Irene M. Pepperberg

Animal Sentience

Chapman & Huffman suggest that humans’ views of their own superiority are a source of their callousness toward the environment. I do not disagree but point to a number of other issues that must be addressed for conservation efforts to succeed.


Taking Exception To Human Exceptionalism, Carrie P. Freeman Jan 2019

Taking Exception To Human Exceptionalism, Carrie P. Freeman

Animal Sentience

Chapman & Huffman refute common claims used to justify human species distinctions, and they critique the animal cruelty that has resulted from this privileged status. I raise related questions for further study of the roots of human exceptionalism and about whether aspiring to be more like our fellow animals might be part of the solution.


Mirror Neurons And Humanity’S Dark Side, Gisela Kaplan Jan 2019

Mirror Neurons And Humanity’S Dark Side, Gisela Kaplan

Animal Sentience

The last two decades have revealed brain mechanisms in birds and primates showing that, contrary to earlier prejudices, some birds can do things (cognitive and affective) on par with or even better than great apes and humans. The old dichotomies are breaking down; but the dark side is that these insights come at a time in the Anthropocene when humans have caused and continue to cause mass extinctions.


Anthropocentrism: Practical Remedies Needed, Helen Kopnina Jan 2019

Anthropocentrism: Practical Remedies Needed, Helen Kopnina

Animal Sentience

It is true that one of the harmful consequences of creating categories where one group is unique and superior to others is that it justifies discriminating against the inferior groups. And outright abuse of nonhuman animals is indeed morally unjustifiable. But what is to be done about it?


Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan Jan 2019

Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan

Animal Sentience

Humans have long viewed themselves in a favorable light. This bias is consistent with a general pattern of self-enhancement. Neural systems in the medial prefrontal cortex underlie this way of thinking, which, even when false, may be beneficial for survival. It is hence not surprising that we often disregard contrary evidence in believing ourselves superior.


Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez Jan 2019

Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez

Animal Sentience

Chapman & Huffman argue that, because humans are neither unique nor superior to the other animals, cruelty to animals is not justified. Though I agree with their conclusion, I do not think their argument works. Many human beings do have some capacities that animals do not have and are greater in some respects, in the sense of having superior abilities. It is a better argument to deny that any of that is morally relevant. Sentience suffices for moral consideration, and for deriving a moral duty not to harm other animals and to assist them when they are in need.


Is Human Uniqueness Fake News?, Sean Hermanson Jan 2019

Is Human Uniqueness Fake News?, Sean Hermanson

Animal Sentience

The world and its troubles don't need unfounded denials of human uniqueness.


Superior Or Inferior, Human Uniqueness Is Manifold, Scott Atran Jan 2019

Superior Or Inferior, Human Uniqueness Is Manifold, Scott Atran

Animal Sentience

Chapman & Huffman (C & H) contend that, as with all biological traits, there is evolutionary continuity underlying cognitive and social traits previously thought to be unique to humans. Yet C & H, like Darwin, appeal to a seemingly unique moral aptitude that enables humans to be kind to conspecific strangers and other species.


Why Cod Don't Like To Sunbathe: Quantity And Quality In The Animal Kingdom, Christoph Jung Jan 2019

Why Cod Don't Like To Sunbathe: Quantity And Quality In The Animal Kingdom, Christoph Jung

Animal Sentience

The difference between a cod and a lizard is not just a quantitative one. The recognition of qualitative differences between species does not imply a moral ranking. Our species’ special abilities to shape the earth mean we have a special responsibility for ensuring a liveable future for all organisms, human and non-human.
