The Object Of Grief, Clark Glymour
The Object Of Grief, Clark Glymour
Animal Sentience
King’s new book is a wonderful collection of diverse anecdotes illustrating the variety of animal practices that are convincing illustrations of grief. Those who want scientific arguments for that conclusion should, however, read elsewhere.
An Invertebrate Perspective On Pain, Jennifer A. Mather
An Invertebrate Perspective On Pain, Jennifer A. Mather
Animal Sentience
Although Key (2016) argues that mammals feel pain and fish do not, from an invertebrate perspective, it is obvious that the pain experience is shared by animals from a number of different animal groups.
Nonhuman Mind-Reading Ability, Marthe Kiley-Worthington
Nonhuman Mind-Reading Ability, Marthe Kiley-Worthington
Animal Sentience
Harnad (2016) is mistaken that humans are better at mind-reading than other species. Humans have context-independent language, but nonhuman species, especially mammals, have context-dependent nonverbal skills – perceptual, communicative and social -- that can be much keener than our own.
Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom
Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom
Animal Sentience
The concept of sentience concerns the capacity to have feelings. There is evidence for sophisticated cognitive concepts and for both positive and negative feelings in a wide range of nonhuman animals. All vertebrates, including fish, as well as some molluscs and decapod crustaceans have pain systems. Most people today consider that their moral obligations extend to many animal species. Moral decisions about abortion, euthanasia, and the various ways we protect animals should take into account the research findings about sentience. In addition, all animal life should be respected and studies of the welfare of even the simplest invertebrate animals should …
Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke
Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke
Animal Sentience
Broom’s (2014) book is a well-researched and thoroughly written exploration and evaluation of the journey from the origins of animal welfare science to what we can say we now know and need to consider in relation to animal sentience and welfare. This book will help to counter any skepticism among academics and policy makers.
Why Fish Do Not Feel Pain, Brian Key
Why Fish Do Not Feel Pain, Brian Key
Animal Sentience
Only humans can report feeling pain. In contrast, pain in animals is typically inferred on the basis of nonverbal behaviour. Unfortunately, these behavioural data can be problematic when the reliability and validity of the behavioural tests are questionable. The thesis proposed here is based on the bioengineering principle that structure determines function. Basic functional homologies can be mapped to structural homologies across a broad spectrum of vertebrate species. For example, olfaction depends on olfactory glomeruli in the olfactory bulbs of the forebrain, visual orientation responses depend on the laminated optic tectum in the midbrain, and locomotion depends on pattern generators …
Sentience And Animal Welfare: New Thoughts And Controversies, Donald M. Broom
Sentience And Animal Welfare: New Thoughts And Controversies, Donald M. Broom
Animal Sentience
Sentience involves having some degree of awareness but awareness of self is not as complex as some people believe. Fully functioning vertebrate animals, and some invertebrates, are sentient but neither humans nor non-humans are sentient early in development or if brain-damaged. Feelings are valuable adaptive mechanisms and an important part of welfare but are not all of welfare so the term welfare refers to all animals, not just to sentient animals. We have much to learn about what non-human animals want from us, the functioning of the more complex aspects of their brains and of our brains and how we …
Animal Mourning: Précis Of How Animals Grieve (King 2013), Barbara J. King
Animal Mourning: Précis Of How Animals Grieve (King 2013), Barbara J. King
Animal Sentience
Abstract: When an animal dies, that individual’s mate, relatives, or friends may express grief. Changes in the survivor’s patterns of social behavior, eating, sleeping, and/or of expression of affect are the key criteria for defining grief. Based on this understanding of grief, it is not only big-brained mammals like elephants, apes, and cetaceans who can be said to mourn, but also a wide variety of other animals, including domestic companions like cats, dogs, and rabbits; horses and farm animals; and some birds. With keen attention placed on seeking where grief is found to occur and where it is absent …
Cognitive Evidence Of Fish Sentience, Jonathan Balcombe
Cognitive Evidence Of Fish Sentience, Jonathan Balcombe
Animal Sentience
I present a little-known example of flexible, opportunistic behavior by a species of fish to undermine Key’s (2016) thesis that fish are unconscious and unable to feel. Lack of a cortex is flimsy grounds for denying pain to fish, for on that criterion we must also then deny it to all non-mammals, including birds, which goes against scientific consensus. Notwithstanding science’s fundamental inability to prove anything, the precautionary principal dictates that we should give the benefit of the doubt to fish, and the state of the oceans dictates that we act on it now.
A Single Strand Of Argument With Unfounded Conclusion, Robert W. Elwood
A Single Strand Of Argument With Unfounded Conclusion, Robert W. Elwood
Animal Sentience
Key (2016) describes the neural system involved in human pain experience in an excellent fashion but then suggests that only that complete system can generate the experience of pain. Thus animals without all components will not feel pain. This argument has been refuted in the past by analogy to vision where it is clear that a broad range of taxa, vertebrate and invertebrate, have good visual abilities albeit with completely different central nervous systems and receptors. This known counterargument to Key’s main idea is not mentioned in the target article. Further criteria that might indicate pain and studies examining these …
Pain In Parallel, Peter Godfrey-Smith
Pain In Parallel, Peter Godfrey-Smith
Animal Sentience
Key's (2016) arguments against the view that fish feel pain can be shown to be fallacious by considering some damage-related behaviors in invertebrates. Pain may have different neural bases in different organisms, so the absence in fish of the cortical structures that might underlie pain in mammals does not settle the question of fish pain.
Pain In Fish: Weighing The Evidence, James D. Rose
Pain In Fish: Weighing The Evidence, James D. Rose
Animal Sentience
The target article by Key (2016) examines whether fish have brain structures capable of mediating pain perception and consciousness, functions known to depend on the neocortex in humans. He concludes, as others have concluded (Rose 2002, 2007; Rose et al. 2014), that such functions are impossible for fish brains. This conclusion has been met with hypothetical assertions by others to the effect that functions of pain and consciousness may well be possible through unknown alternate neural processes. Key's argument would be bolstered by consideration of other neurological as well as behavioral evidence, which shows that sharks and ray are fishes …
Where Is Pain In The Brain?, Marshall Devor
Where Is Pain In The Brain?, Marshall Devor
Animal Sentience
Key argues that fish cannot experience pain based on (1) brain imaging in humans, (2) consequences of lesions and (3) direct brain stimulation. Imaging indeed shows that pain-relevant signals reach the cortex, but not that they underlie the subjective experience of pain. Lesions and stimulation data are more to the point, but Key paints an idiosyncratic and misleading picture of their effects. S1 and S2 ablation does not eliminate evoked or spontaneous pain, although there may be up- or down-modulation. Likewise, stimulation of pain-associated cortical areas rarely induces pain, and pain almost never occurs at the onset of epileptic seizures. …
Falsifying The Null Hypothesis That “Fish Do Not Feel Pain", Brian Key
Falsifying The Null Hypothesis That “Fish Do Not Feel Pain", Brian Key
Animal Sentience
The reader of Animal Sentience may surmise that because the weight of the commentaries on my target article, “Why fish do not feel pain,” is leaning towards not supporting my argument, it follows that the premise "fish do not feel pain" is incorrect. However, science does not prevail by popular opinion. History is plagued with numerous (and often widely accepted) examples of biological phenomena being explained by mysterious forces. In the absence of a mechanistic understanding, the many different guises of vitalism (the principle that life involves a vital energy) are often invoked to explain the unknown. Spurious …
Pain And Fish Welfare, Eliane Gonçalves-De-Freitas
Pain And Fish Welfare, Eliane Gonçalves-De-Freitas
Animal Sentience
The evolutionary approach of Key’s (2016) target article, generically comparing humans with fish of all kinds, is simplistic. The author ignores published research on structural and molecular aspects of pain in fish. The target article reads more like a selective polemic against fish welfare than an even-handed analysis.
Understanding Emotional Suffering, Barbara J. King
Understanding Emotional Suffering, Barbara J. King
Animal Sentience
In responding to insightful commentaries from 7 scholars, for which I am grateful, I offer new thoughts on whether animals can conceptualize and express signs of grief. I also discuss why I included both weak and strong examples of animal mourning, and how this work may help us think about enhanced welfare for animals, including freedom from emotional suffering.
Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan
Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan
Animal Sentience
According to Broom (2014), animal welfare is a concept that can be applied to all animals, including single-celled organisms that are obviously not sentient. Such a stance makes it difficult to draw a connection between welfare and sentience, and that is the book’s downfall. Some excellent points are made about sentience and there are very good discussions on animal welfare. However, unless sentience is considered the essential component of welfare, any attempt to link the two phenomena will be unsuccessful — and that, indeed, is the case with this book.
How Welfare Biology And Commonsense May Help To Reduce Animal Suffering, Yew-Kwang Ng
How Welfare Biology And Commonsense May Help To Reduce Animal Suffering, Yew-Kwang Ng
Animal Sentience
Welfare biology is the study of the welfare of living things. Welfare is net happiness (enjoyment minus suffering). Since this necessarily involves feelings, Dawkins (2014) has suggested that animal welfare science may face a paradox, because feelings are very difficult to study. The following paper provides an explanation for how welfare biology could help to reduce this paradox by answering some difficult questions regarding animal welfare. Simple means based on commonsense could reduce animal suffering enormously at low or even negative costs to humans. Ways to increase the influence of animal welfare advocates are also discussed, focusing initially on farmed …
Why Animal Welfarism Continues To Fail, Lori Marino
Why Animal Welfarism Continues To Fail, Lori Marino
Animal Sentience
Welfarism prioritizes human interests over the needs of nonhuman animals. Despite decades of welfare efforts other animals are mostly worse off than ever before, being subjected to increasingly invasive and harmful treatments, especially in the factory farming and biomedical research areas. A legal rights-based approach is essential in order for other animals to be protected from the varying ethical whims of our species.
End-State Welfarism, Joel Marks
End-State Welfarism, Joel Marks
Animal Sentience
Yew-Kwang Ng’s research is the work of an obviously sincere, intelligent, and conscientious animal advocate. But I am unable to accept his starting assumption that animal welfare is an appropriate basis for animal ethics. More specifically I argue that animal welfare as a means to animal liberation is an issue that can be debated, but animal welfare as the ultimate end or goal of animal advocacy is misguided.
