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.


Animal Cognition: Quantity Has A Quality Of Its Own, Ivaylo Borislavov Iotchev, Kauê Machado Costa Jan 2019

Animal Cognition: Quantity Has A Quality Of Its Own, Ivaylo Borislavov Iotchev, Kauê Machado Costa

Animal Sentience

Chapman & Huffman’s moral analysis fails to prove that the exploitation of animals or the environment is causally connected to beliefs about human capacities. Their exposition of the philosophical interpretations of animal cognition ignores historical context and confounds different levels of analysis. Their analysis of the scientific literature, from which they conclude that humans should not be considered as different from other animals, does not take into account many recent psychological and neuroscientific developments and rests upon a flawed understanding of the relationship between gradual and categorical differences, misrepresenting the two as mutually exclusive concepts.


Intelligence As Mental Manipulation In Humans And Nonhuman Animals, Moran Bar-Hen-Schweiger, Avishai Henik Jan 2019

Intelligence As Mental Manipulation In Humans And Nonhuman Animals, Moran Bar-Hen-Schweiger, Avishai Henik

Animal Sentience

Chapman & Huffman review and evaluate various aspects of the notion of human superiority. In this commentary we focus on intelligence and suggest a biologically based view of intelligence applicable to humans and non-human species alike. “Mental manipulation” (e.g., mental transformations, rotations, perspective-taking), an extension of object manipulation, provides a continuous, biologically based concept for studying intelligent behavior in humans and other species and challenges the notion of human superiority.


Adding Sheep To The Spectrum Of Comparative Psychology, James King Jan 2019

Adding Sheep To The Spectrum Of Comparative Psychology, James King

Animal Sentience

Marino & Merskin’s comprehensive review of cognitive complexity in sheep is a laudable and important contribution to comparative psychology. It is also valuable because it shows promising directions for future research on this neglected species. The relatively small number of neurons in the bovid cerebral cortex indicates that sheep cognitive performance on traditional measures of complex learning is limited. Nevertheless, the social and emotional complexity of sheep underscores the importance of further research into domains including personality and psychological well-being.


What Is In An Octopus's Mind?, Jennifer Mather Jan 2019

What Is In An Octopus's Mind?, Jennifer Mather

Animal Sentience

It is difficult to imagine what an animal as different from us as the octopus ‘thinks’, but we can make some progress. In the Umwelt or perceptual world of an octopus, what the lateralized monocular eyes perceive is not color but the plane of polarization of light. Information is processed by a bilateral brain but manipulation is done by a radially symmetrical set of eight arms. Octopuses do not self-monitor by vision. Their skin pattern system, used for excellent camouflage, is open loop. The output of the motor system of the eight arms is organized at several levels — brain, …


What And Where Is An Octopus’S Mind?, Jennifer A. Mather Jan 2019

What And Where Is An Octopus’S Mind?, Jennifer A. Mather

Animal Sentience

It is gratifying to see the thorough discussion of whether octopuses have a mind, though perhaps a mind that is different from those of “higher” vertebrates. It stimulates us to look at the welfare of these animals and challenges us to find better ways to test mindfulness and cognition across animals with widely differing natural histories and sensory and motor capacities.


What Should We Do About Sheep? The Role Of Intelligence In Welfare Considerations, Heather Browning Jan 2019

What Should We Do About Sheep? The Role Of Intelligence In Welfare Considerations, Heather Browning

Animal Sentience

Marino & Merskin (2019) demonstrate that sheep are more cognitively complex than typically thought. We should be cautious in interpreting the implications of these results for welfare considerations to avoid perpetuating mistaken beliefs about the moral value of intelligence as opposed to sentience. There are, however, still important ways in which this work can help improve sheeps’ lives.


Can A Mirror Capture The Self?, Cynthia Willett Jan 2019

Can A Mirror Capture The Self?, Cynthia Willett

Animal Sentience

Is the mirror a reliable indicator of self-awareness for any species, whether sheep or human? Taking a cue from feminist, phenomenological, and cross-cultural philosophy, a relational self rather than a reflective one might better capture what is at stake for the lives of social animals and for science.


More Evidence Of Complex Cognition In Nonhuman Species, Lesley J. Rogers Jan 2019

More Evidence Of Complex Cognition In Nonhuman Species, Lesley J. Rogers

Animal Sentience

Chapman & Huffman have highlighted observations of animals performing, in nature, complex behaviour once thought to be unique to humans. Just as relevant to their argument are examples of cognition shown by domesticated species tested in controlled conditions. These strengthen the case for human/nonhuman similarities in behaviour and cognition. Recent research has brought to our attention the ability of nonhuman species to perform many tasks previously considered to be the hallmark of humans. Even though different species may use different ways of solving these tasks, the very fact that they can do it undermines the notion of human superiority.


Non-Human Animals Providing Rescue In Medical Emergencies, Rainer Spiegel Jan 2019

Non-Human Animals Providing Rescue In Medical Emergencies, Rainer Spiegel

Animal Sentience

In their target article, Chapman & Huffman challenge the quotation of Sir William Osler that the desire to take medication distinguishes humans from non-human animals. They provide examples of self-medication in non-human animals. Based on these examples, it can be inferred that non-human animals practice at least some form of medicine for symptom control. I would like to extend this view by showing that non-human animals not only provide self-medication, but also rescue others facing emergencies.


Corticocentric Bias In Cognitive Neuroscience, Orit Nafcha, Shai Gabay Jan 2019

Corticocentric Bias In Cognitive Neuroscience, Orit Nafcha, Shai Gabay

Animal Sentience

Chapman & Huffman (2018) note that our tendency to categorize leads to a sense of human superiority that helps justify violence against nonhuman animals. Yet animals are turning out to have capacities previously thought to be uniquely human. We add a further factor that may contribute to the false sense of human superiority: the "corticocentric" bias of neuroscience. An evolutionary approach may help identify species similarities and differences, providing a better understanding of the uniqueness of each species.


A Community Of Minds, Bennett L. Schwartz Jan 2019

A Community Of Minds, Bennett L. Schwartz

Animal Sentience

Mather (2019) provides an excellent overview of the literature on octopus perception, cognition, memory, and behavior. Anyone interested in cephalopod cognition and brain organization will find her target article informative and interesting. In this commentary, I challenge the idea that an individual organism must have an individual mind. Given the structure of the octopus brain and their complex behavior, one must consider the possibility that an octopus is a community of minds rather than a single mind.


Are Octopuses Special? Mind, Sociality And Life History, Phyllis C. Lee Jan 2019

Are Octopuses Special? Mind, Sociality And Life History, Phyllis C. Lee

Animal Sentience

Understanding the Umwelt or being-ness of an octopus is a fascinating problem. Mather’s review provides us with significant insights into the ways of living of non-humans that exploit a perceptual and physical world we can only guess at. Octopus “distributed minds” call into question our primate-based understandings of the importance of sociality and the pace of life in the evolution of complex perceptual and behavioural abilities.


The Octopus Mind And The Argument Against Farming It, Jennifer Jacquet, Becca Franks, Peter Godfrey-Smith Jan 2019

The Octopus Mind And The Argument Against Farming It, Jennifer Jacquet, Becca Franks, Peter Godfrey-Smith

Animal Sentience

Mather is convincing about octopuses having ‘a controlling mind, motivated to gather information,’ but stops short of asking what having that mind means for octopus moral standing. One consequence of understanding the octopus mind should be a refusal to subject octopuses to mass production. Octopus farming is in an experimental phase and supported by various countries. We argue that it is unethical because of concerns about animal welfare as well as environmental impacts.


Octopus Intelligence: The Importance Of Being Agnostic, Piero Amodio Jan 2019

Octopus Intelligence: The Importance Of Being Agnostic, Piero Amodio

Animal Sentience

Mather’s (2019) provocative claim that octopuses have a mind hinges on the inference that their striking behavioural flexibility is evidence of “complex” cognitive abilities. I discuss alternative explanations — not to deny the possibility of complexity but to point out that current evidence does not allow us to draw firm conclusions. Only an agnostic approach will lead to the systematic investigation of octopus behaviour and ultimately, greater insights into the cognitive capacities of these fascinating creatures.


Octopus: Multiple Minds Or Just A Slow Thinker?, Shelley A. Adamo Jan 2019

Octopus: Multiple Minds Or Just A Slow Thinker?, Shelley A. Adamo

Animal Sentience

An octopus has more neurons in their peripheral nervous system (PNS) than in their brain. PNS neurons could participate in forming cognitive networks with the central brain in the same way that the cerebellum is now thought to contribute to mammalian cognition. However, cephalopods lack myelinated fibres, which might decrease the ability of the PNS to participate in cognitive networks. The lack of myelinated fibres may also select for a less integrated brain, with an increased emphasis on local information processing. Alternatively, integration may still occur across distant neural centers, but proceed more slowly in cephalopods than in mammals.


What We Don't Know About Cephalopods And How To Define It, Catia Correia Caeiro Jan 2019

What We Don't Know About Cephalopods And How To Define It, Catia Correia Caeiro

Animal Sentience

Despite the reputation of octopuses as intelligent animals, their cognitive abilities seem to be mostly unknown. This should be the starting point of a long process of scientific enquiry about these taxa, which must include discussions on operational definitions first and foremost. Discussing octopus mind might prove fruitless without more basic concepts. Some approaches are suggested here.


Taking Darwinism Seriously, Carsta Simon Jan 2019

Taking Darwinism Seriously, Carsta Simon

Animal Sentience

Chapman & Huffman propose that dropping the categorical distinction between human and nonhuman animals may reduce the atrocious acts of humans towards nonhuman animals, but will it? Taking Darwinism seriously means accepting physical and behavioral continuity across species, including the capacity to feel pain.


Phooey On Comparisons, Gwen J. Broude Jan 2019

Phooey On Comparisons, Gwen J. Broude

Animal Sentience

Chapman & Huffman reject the notion that human beings are very different from other animals. The goal is to undermine the claim that human uniqueness and even superiority are reason enough to treat other animals badly. But evaluating human uniqueness for this purpose only plays into the hands of those who exploit invidious comparisons between us and other animals to justify mistreatment of the rest of the animal kingdom. What human uniqueness we may discover would still be no justification for how we behave toward other animals. We should also ask ourselves whether any human-centric criterion can be justification for …


Across The Great Divide, Debra Merskin Jan 2019

Across The Great Divide, Debra Merskin

Animal Sentience

Chapman & Huffman’s target article calls for a reevaluation of claims of human uniqueness and superiority. It also adds to the literature on how species differences, as Darwin noted, are more of degree than kind. The threats to environmental health and species survival are a consequence of excluding nonhuman animals from moral concern and consideration. The theory of intersectionality should include speciesism in the array of discriminatory practices.


Octopus Experience, Peter Godfrey-Smith Jan 2019

Octopus Experience, Peter Godfrey-Smith

Animal Sentience

The first part of this commentary attempts to get "inside" the octopus mind a little further than Mather does, drawing on her description of octopus cognition in many places but diverging in others. The second part outlines other disagreements with her account of the animals, especially in the area of social behavior.


Casting A Sheep’S Eye On Science, David M. Peña-Guzmán Jan 2019

Casting A Sheep’S Eye On Science, David M. Peña-Guzmán

Animal Sentience

Marino & Merskin review evidence that sheep are not just passive and reactive creatures. They have personalities that vary from individual to individual and endure over time. It follows that we must rethink what it means to study them scientifically.


A Behavior-Analytic Approach To Understanding Octopus “Mind”, Lindsay R. Mehrkam Jan 2019

A Behavior-Analytic Approach To Understanding Octopus “Mind”, Lindsay R. Mehrkam

Animal Sentience

Mather makes a convincing case for octopus sentience based on a lot of evidence of their complex learning capabilities. It should follow from Mather’s findings that these intelligent invertebrates are worthy of welfare considerations, just as vertebrate species with similar capabilities are. I provide a complementary environment-behavior analysis of how we might understand the world of the octopus more straightforwardly, borrowing from Mather’s examples, to show how to promote opportunities for complex learning and species-typical behaviors in the octopus.


Chickens Play To The Crowd, Cinzia Chiandetti Jan 2018

Chickens Play To The Crowd, Cinzia Chiandetti

Animal Sentience

The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.


Post-Darwin Skepticism And Run-Of-The-Mill Suicide, John Hadley Jan 2018

Post-Darwin Skepticism And Run-Of-The-Mill Suicide, John Hadley

Animal Sentience

Peña-Guzmán’s depiction of the opponent of animal suicide as a conservative is a straw man. It is possible to accept that animals are self-conscious and reflexive yet still reject the view that they have the mental wherewithal to commit run-of-the-mill suicide. That animal behaviour can be positioned on a continuum of self-destructive behaviour does not establish that animals can intentionally kill themselves.


An Adaptationist Perspective On Animal Suicide, Timothy P. Racine Jan 2018

An Adaptationist Perspective On Animal Suicide, Timothy P. Racine

Animal Sentience

Peña-Guzmán’s discussion of suicide in nonhuman animals has broad implications. In this commentary, I focus on the logical relation between suicide and intention. Proximate cause must be distinguished from ultimate function in explanations of suicide. I briefly discuss two adaptationist accounts of suicidal behavior.


Lessons From Chimpanzee Sign Language Studies, Mary Lee Jensvold Jan 2018

Lessons From Chimpanzee Sign Language Studies, Mary Lee Jensvold

Animal Sentience

Claims are often made about behaviors being unique to humans; the evidence usually shows they are not. Sign language studies on chimpanzees may provide a useful model for comparative studies of suicide. A productive approach to comparative studies is to focus on observable behaviors rather than getting lost in the pitfalls of vague definitions and changing measures.


Can Nondolphins Commit Suicide?, David M. Peña-Guzmán Jan 2018

Can Nondolphins Commit Suicide?, David M. Peña-Guzmán

Animal Sentience

This Response addresses the scientific and philosophical criticisms of my 2017 target article “Can nonhuman animals commit suicide?” It defends my key claims and explores topics (such as animal judgment, animal theory of mind, and the evolution of suicide) that did not appear in the original article. It also points out areas in which further research is needed and concludes that we should be wary of accusations of “anthropomorphism” in debates about animal suicide.
