Beyond The Neocortex: Pallial Routes To The Edge Of Sentience, Oryan Zacks
Beyond The Neocortex: Pallial Routes To The Edge Of Sentience, Oryan Zacks
Animal Sentience
In The Edge of Sentience, the sentience candidacy of fishes and reptiles is strengthened if one accepts midbrain-centric theories of human consciousness. In this commentary I attempt to untether the two positions. I suggest that we need not look for a one-to-one match between the neocortex and a single pallial structure outside of mammals. Instead, a sufficient similarity might exist between the mammalian neocortex and the combination of pallium and midbrain in fishes and reptiles. Adopting an evolutionary perspective in the study of vertebrate brains could point to new investigation priorities in human and animal research.
Beyond Better Conditions: Seaweed Farming And The Number Of Sentient Animals In Aquaculture, Shrilaxmi Patil, Matthew Unerman, Wasseem Emam
Beyond Better Conditions: Seaweed Farming And The Number Of Sentient Animals In Aquaculture, Shrilaxmi Patil, Matthew Unerman, Wasseem Emam
Animal Sentience
Oldfield & Bonano (2024) (O&B) document how far fish welfare research lags behind welfare research in other animals. We share O&B’s feelings-based concept of welfare and agree that aquaculture seeded this field; but research volume has not scaled with animal numbers: Welfare attention per farmed fish or decapod remains negligible. Along the lines of preceding commentaries (Maia 2024, Mather 2024), we treat farmed aquatic animals as individuals rather than tonnage. We then raise a point so far absent from the commentary on O&B so far: reducing the number of sentient animals entering intensive systems. Coastal seaweed farming, which cultivates non-sentient …
Ai Is Not The Kind Of Thing That Can Ever Be Sentient, Lori Marino
Ai Is Not The Kind Of Thing That Can Ever Be Sentient, Lori Marino
Animal Sentience
Sentience evolved to allow organisms to move through their environment avoiding harms and achieving benefits. Sentience did not evolve from computation. It evolved from valenced feelings. AI (even robots) are not embodied and are not the kind of thing that needs to be sentient. There is no way to get from computations to feelings. They are qualitatively different things. We should avoid being lulled into thinking that an inanimate object designed to engage our propensity for anthropomorphism, like AI, is actually a mind.
Dimensional Welfare Beyond Pain: Extending The Precautionary Principle In Birch’S “The Edge Of Sentience”, Willa M. Lane, Nicola S. Clayton
Dimensional Welfare Beyond Pain: Extending The Precautionary Principle In Birch’S “The Edge Of Sentience”, Willa M. Lane, Nicola S. Clayton
Animal Sentience
Birch's (2024) The Edge of Sentience identifies sentience candidates primarily through the pain-focused LSE Criteria. Yet, as Birch himself notes in Proposal 17, sentience is not pain. We argue that statutory welfare protections must therefore reach beyond pain, and that the right tool for doing so is Birch et al.’s (2020) dimensionality framework, which characterises conscious experience across five domains. Used together, the LSE Criteria establish that welfare is at stake, while the dimensionality framework maps what is at stake beyond pain to provide a taxon-specific profile of where captivity impoverishes experience. We apply this approach to invertebrate welfare and …
On The Edge Of Science?, Mark Briffa, Lynne U. Sneddon
On The Edge Of Science?, Mark Briffa, Lynne U. Sneddon
Animal Sentience
In The Edge of Sentience, Jonathan Birch (2024) provides a thought-provoking synthesis of current perspectives on animal (and artificial) sentience. He addresses the question from conceptual, ethical, regulatory and empirical viewpoints. Here we focus on some of the scientific issues raised, including defining and operationalising the concept of sentience and the implications for policy and regulation. Despite unresolved conceptual challenges, the book makes a compelling case for the continued scientific investigation of animal sentience.

From The Edge To The Grounds Of “Sentientism”, David Degrazia
Animal Sentience
Birch’s book is a remarkable exploration of the nature of sentience, its moral salience, evidence for its presence, and how to arrive at humane policies regarding our treatment of human beings, animals, brain organoids, and AI systems of uncertain sentience. Although Birch endorses the view that sentience is of fundamental moral importance, he endeavors to remain neutral among reasonable moral views and work out how to navigate through uncertainty—both ethical and epistemological—to arrive at defensible policies. While making common cause with Birch’s project, my own recent book advances a developed case in favor of the “sentientism” Birch endorses.
Natural Behavior Vs. Subjective Experience In Fish Welfare Assessments, Ronald G. Oldfield
Natural Behavior Vs. Subjective Experience In Fish Welfare Assessments, Ronald G. Oldfield
Animal Sentience
Several commentaries on the Oldfield & Bonano (2024) target article proposed that natural behavior should play a larger role in assessing the welfare of fishes in zoos and aquariums. However, the natural-behavior concept of animal welfare has been widely criticized because natural behaviors do not necessarily improve welfare, and unnatural behaviors do not necessarily reduce it. I review the three major concepts of animal welfare — physical health, natural behavior, and affect/feelings — and argue that behavior patterns, whether natural or otherwise, should be evaluated according to their effects on health and subjective experience. Using the affect/feelings concept and the …
Aggression And Fish Welfare: Challenges And Opportunities, Christine M. Soper, Peter D. Dijkstra
Aggression And Fish Welfare: Challenges And Opportunities, Christine M. Soper, Peter D. Dijkstra
Animal Sentience
Oldfield & Bonano’s (2024) [O&B] target article discusses the wellbeing and sociality of bony fishes. Many fish species, such as cichlids, are not only social but territorial. Aggression is normal, but territorial aggression in a captive environment can have a negative impact on welfare. Aggression-related injuries and deaths are prevalent in pet stores as well as research settings. We discuss the need to develop effective methods to minimize the negative consequences of aggression.
Both Studying And Protecting Octopuses “On Their Own Terms”, Jennifer Jacquet, Janelle Kaz, Becca Franks, Christine Webb
Both Studying And Protecting Octopuses “On Their Own Terms”, Jennifer Jacquet, Janelle Kaz, Becca Franks, Christine Webb
Animal Sentience
Cephalopods – indeed, all animals – “must be seen on their own terms,” with respect for their autonomy and their ecological imperatives. This will provide greater scientific insight along with a more ethical and accurate understanding of minds beyond our own.
Cephalopod Consciousness On “Their Own Terms”: Who Are “They”?, Willa M. Lane, Victor Ajuwon, Nicola S. Clayton
Cephalopod Consciousness On “Their Own Terms”: Who Are “They”?, Willa M. Lane, Victor Ajuwon, Nicola S. Clayton
Animal Sentience
Mather’s call to consider cephalopods’ consciousness “on their own terms” raises the question of the extent to which cephalopods can be considered a homogenous group. While coloeoid cephalopods share traits that strongly distinguish them from other molluscs and invertebrates, they show vast ecological and morphological diversity, with implications for the design of empirical investigations of consciousness. Extending Mather’s argument, we apply Birch et al.’s (2020) five-dimensional model to compare octopus, cuttlefish, squid, and nautilus. This comparison shows that even within a graded rather than categorical framework, putative consciousness profiles depend on which taxa are included in discussions of “cephalopod consciousness.” …
Précis Of The Edge Of Sentience: Risk And Precaution In Humans, Other Animals, And Ai, Jonathan Birch
Précis Of The Edge Of Sentience: Risk And Precaution In Humans, Other Animals, And Ai, Jonathan Birch
Animal Sentience
We often face grave practical decisions that seem to hinge on whether a system is sentient. This family of cases includes invertebrate animals, people who are unresponsive after brain injury, fetuses, neural organoids, and now AI technologies. We must decide what to do despite ongoing disagreement about the nature of sentience. In our state of uncertainty, we should pragmatically transform the question from “Is it sentient?” to “Is it a sentience candidate, an investigation priority, or neither?”. When a system is a sentience candidate, it is negligent to fail to consider precautions. We should instead evaluate precautions for their proportionality …
What Is It Like To Be A Cognitive Ethologist?, Anne Wordsworth She/Her
What Is It Like To Be A Cognitive Ethologist?, Anne Wordsworth She/Her
Animal Sentience
Donald Griffin not only made the study of animal minds acceptable for scientific investigation but the work of the cognitive ethologists that he inspired made animals and their lives fascinating and accessible to the greater public. The scrupulously detailed examination of his life and work by Ristau ensures that this history will always be there to respect his work and his legacy
Can We Use Judgement Bias To Assess The Welfare Of Fish In Aquariums And Zoos?, Culum Brown
Can We Use Judgement Bias To Assess The Welfare Of Fish In Aquariums And Zoos?, Culum Brown
Animal Sentience
This commentary examines the potential of tests of judgment bias to assess fish welfare in aquariums and zoos. Judgment bias offers a non-invasive approach to interpreting affective states in animals, using cognitive responses to ambiguous stimuli as indicators of mental wellbeing. Despite the constraints of captive environments—such as limited handling and species diversity in exhibits—recent adaptations of judgment-bias protocols make them suitable across taxa, including fishes. Collaborations with progressive zoos and aquariums could facilitate this research, based on the shared goal of enhancing animal welfare and promoting public education.
Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano
Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano
Animal Sentience
Research on the behaviour of animals in zoos has been conducted for decades, and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be lacking. Here, we assess the current state of research on fishes in zoos and aquariums by surveying the peer-reviewed literature. Our assessment differs from previous surveys in that we examine the taxonomic classes Chondrichthyes (sharks and rays) and Osteichthyes (bony fishes) separately. Our survey finds that bony fishes have been drastically underrepresented in zoo journals, more drastically than chondrichthyans, revealing an …
Norms And Variance Fail To Predict Butterfly Effects On Social Dynamics By Idiosyncratic Individuals, Stephen F. Stringham, Lynn Rogers, Ann Bryant
Norms And Variance Fail To Predict Butterfly Effects On Social Dynamics By Idiosyncratic Individuals, Stephen F. Stringham, Lynn Rogers, Ann Bryant
Animal Sentience
Adaptations and adjustments to current environmental conditions are manifest in behavioral norms. Knowing norms facilitates population-level prediction, but doesn’t predict individual behavior where idiosyncrasies might trigger “butterfly effects." Knowledge of individual quirks is particularly important for risk assessment and management during close encounters between humans and potentially lethal wildlife, including bears (Ursus spp.). Innovative foraging techniques can alter population vigor and viability. Traits at the tails of a bell curve might hold the greatest potential for adapting to environmental change.
Wildlife Conservation: The Importance Of Individual Personality Traits And Sentience, Karen A. Owens, Gosia Bryja, Marc Bekoff
Wildlife Conservation: The Importance Of Individual Personality Traits And Sentience, Karen A. Owens, Gosia Bryja, Marc Bekoff
Animal Sentience
Individual differences in personality types within the same species have been studied much less than differences between species and populations. Personality differences are related to risk-taking and exploration, which in turn correlate with individuals' daily responses, decisions, and fitness. Bold and shy personality types can have different advantages and disadvantages under different social or environmental pressures. Analyzing personality differences has helped clarify how elk habituate to a well-populated area and how management strategies can be adapted to them. For wolves newly repatriated to Colorado, individual personality factors are likely to prove important for adapting to their new homes as well …
Not Just Bony Fish: All Nonmammalian And Nonavian Animals Are Neglected In Both Welfare And General Research, Jennifer A. Mather Ph.D.
Not Just Bony Fish: All Nonmammalian And Nonavian Animals Are Neglected In Both Welfare And General Research, Jennifer A. Mather Ph.D.
Animal Sentience
The lack of research on fish welfare highlighted by Oldfield & Bonano (2024) is only part of a more general problem: a relative neglect of animals other than mammals and birds. The causes are our lack of knowledge, our negative view of what we consider to be “lower” animals and our underestimation of their intelligence and sensitivity. Our estimation will increase as our knowledge increases. As a broader view spreads to the public through the media, it should gradually increase the demand to expand both research and welfare, especially beyond mammals and birds.
Animal Personality And Sentience As Distinct Concepts, Mark Briffa
Animal Personality And Sentience As Distinct Concepts, Mark Briffa
Animal Sentience
Owens et al (2024) discuss how knowledge of both animal personality and sentience in target populations can be leveraged to enhance wildlife conservation programmes. In this commentary I expand on the distinction between these two concepts. Behavioural differences should be considered broadly across conservation programmes, not just those involving species deemed sentient.
Donald Griffin: A Visionary In Science And Consciousness, Charles Foster
Donald Griffin: A Visionary In Science And Consciousness, Charles Foster
Animal Sentience
Carolyn Ristau’s (2024) timely biography reviews Donald Griffin’s pioneering ideas with depth and historical perspective, describing Griffin’s approach to science, his openness to interdisciplinary insights, and his bold stance on consciousness. Ristau’s work highlights Griffin’s relevance to contemporary debates on consciousness and natural selection.
Don Griffin And The Early Days Of Cognitive Ethology, Gordon M. Burghardt
Don Griffin And The Early Days Of Cognitive Ethology, Gordon M. Burghardt
Animal Sentience
Carolyn Ristau’s trilogy provides a comprehensive account of Donald Griffin’s life and work, with the third volume focusing on cognitive ethology. This commentary focuses primarily on my own interactions with Don, particularly during my sabbatical at Rockefeller University when his campaign for cognitive ethology was gaining momentum. I recount my research on reptile behavior and cognition, my collaboration with Don and others at RU, and my role in advancing his ideas while contextualizing them within 19th-century comparative psychology. I also discuss developments in cognitive ethology, including critical anthropomorphism, the challenges of integrating subjective experience into behavioral science, and Griffin’s lasting …

Other Perspectives On Animals, Their Sentience And Cognition, Joyce M. D'Silva Mrs
Animal Sentience
For those of us who work to achieve legal recognition that animals are sentient beings, and should in many cases be allotted personhood, Donald Griffin is indeed an inspiration and a true game-changer. He put paid to the narrow behaviourist interpretation of animals’ lives promoted by Skinner et al. He became a real heir to Darwin’s belief in animal emotions. He enabled campaigners for animal welfare and indeed animal rights to quote his work as a distinguished scientist to give gravitas to their calls for legal recognition and protection of animals.
An Individuals-Oriented Approach To Conservation, Kristy M. Ferraro
An Individuals-Oriented Approach To Conservation, Kristy M. Ferraro
Animal Sentience
Individual cognitive and emotional differences in personality among animals, along with differences in their behavioral traits, are increasingly important in conservation efforts. It is not only more effective but more ethical to take both collective and individual perspectives into account in both research and practice.
Wildlife Conservation And Adaptation To Humans, Valeria Mazza Phd, Claudio Carere
Wildlife Conservation And Adaptation To Humans, Valeria Mazza Phd, Claudio Carere
Animal Sentience
For many animal species, the ability to adapt to coexistence with the human species and to the environmental changes that humans cause is a biological imperative. This adaptive capacity varies not only between species, but within species. Studying individual differences in animals’ behavioral, cognitive and physiological adaptability is important for integrating ethology and conservation. Findings about animal cognitive capacities, including learning, need to be applied in conservation—but humans need to be educated about ethology, coexistence and conservation too.
Plant Sentience: Not Now, Maybe Later?, Helen Tiffin
Plant Sentience: Not Now, Maybe Later?, Helen Tiffin
Animal Sentience
Segundo-Ortin’s target article provides compelling evidence for physiological and behavioral complexity in plants, bringing us closer to a recognition of some kind of plant cognition – but it does not as yet offer firm grounds for inferring sentience (feeling) in plants, The recent history of the scientific demonstration and recognition of animalsentience in invertebrates, for example, does not entirely rule out the possibility that further research might provide support for plant sentience. Should this ever turn out to be the case, the ethical problems raised are not insurmountable, and would not threaten the now proven case for animal sentience
Plants Detect And Adapt, But Do Not Feel, Paul C. Struik
Plants Detect And Adapt, But Do Not Feel, Paul C. Struik
Animal Sentience
Plant sentience is a hot topic in scientific and popular media. There are moral reasons to respect both the service of plants to humanity and their natural integrity as creatures playing their own significant role in a complex ecosystem. However, to infer that plants have certain cognitive capacities that are present also in certain human and nonhuman animals calls for scientific rigor beyond mere analogy. The unique capacities of plants identified by Segundo-Ortin & Calvo are not necessarily linked to sentience. Nor is it likely that sentience is an evolutionary trait that is present to some extent in all living …

Discovering Dune: Essays On Frank Herbert’S Epic Saga., Edited By Dominic J. Nardi And N. Trevor Brierly, G. Connor Salter
Mythlore: A Journal of J.R.R. Tolkien, C.S. Lewis, Charles Williams, and Mythopoeic Literature
G. Connor Salter reviews Discovering Dune: Essays on Frank Herbert’s Epic Saga, edited by Dominic J. Nardi and N. Trevor Brierly, considering its new contributions to studies of Frank Herbert's work. Essays included fit into four categories (Politics and Power, History and Religion, Biology and Ecology, and Philosophy, Choice and Ethics) and range from Herbert's use of ecology in Dune to how game theory may help explain certain characters' apparent ability to see the future. Discovering Dune also includes an appendix which contains the only up-to-date bibliography of Herbert's work (primary and secondary sources).
Plant Sentience Revisited: Sifting Through The Thicket Of Perspectives, Paco Calvo, Miguel Segundo-Ortin
Plant Sentience Revisited: Sifting Through The Thicket Of Perspectives, Paco Calvo, Miguel Segundo-Ortin
Animal Sentience
In our target article (Segundo-Ortin & Calvo 2023), we proposed the intriguing possibility of plant sentience, drawing parallels with non-human animal studies. This response aims to sift through the rich thicket of perspectives offered by our commentators. To do so, we assess the risks of employing double standards, as well as the tendencies of anthropomorphizing and zoomorphizing in plant studies. We also emphasize the need for clarity in linguistic and conceptual terms, examine the neurophysiological evidence for plant sentience, and discuss the ethical implications of such recognition.

One of the commentaries on the target article notes that "animal sentience" is difficult to define operationally. This response to the commentaries develops a working, usable definition of animal sentience and examines the relationships between animal emotions and sentience.
Plant Sentience? Between Romanticism And Denial: Science, Miguel Segundo-Ortin, Paco Calvo
Plant Sentience? Between Romanticism And Denial: Science, Miguel Segundo-Ortin, Paco Calvo
Animal Sentience
A growing number of non-human animal species are being seriously considered as candidates for sentience, but plants are either forgotten or explicitly excluded from these debates. In our view, this is based on the belief that plant behavior is hardwired and inflexible and on an underestimation of the role of plant electrophysiology. We weigh such assumptions against the evidence to suggest that it is time to take seriously the hypothesis that plants, too, might be sentient. We hope this target article will serve as an invitation to investigate sentience in plants with the same rigor as in non-human animals.
Between Choice And Compulsion: An Examination And Critique Of The Evolution Of 'Original Sin', Matthew James Wynn
Between Choice And Compulsion: An Examination And Critique Of The Evolution Of 'Original Sin', Matthew James Wynn
Graduate Theses/Dissertations
“Why are we the way that we are?” is one of the hardest questions to answer because it requires grasping the origin of human beings. This has left philosophers and theologians in century-long debates on forming a “cosmogony of ontology” (i.e., how the origin of the universe informs the human condition). The concept, “original sin” was developed by a North African theologian named Augustine (354 – 430 CE). Augustine’s reading of Genesis 3, and inaccurate translation of Romans 5:12, taught that a person is born morally culpable for a fault antecedent to their existence. This way of thinking about the …
