The Science Of Animal Sentience And The Politics Of Animal Welfare Should Be Kept Separate, Marian Stamp Dawkins
The Science Of Animal Sentience And The Politics Of Animal Welfare Should Be Kept Separate, Marian Stamp Dawkins
Animal Sentience
Although linked historically by Rowan et al., the scientific study of animal sentience and political campaigns to improve animal welfare should be kept separate, for at least two reasons. First, the separation makes it clear that standards of evidence acceptable for ethical or political decisions on animal welfare can be lower than those required for a rigorously scientific approach to animal sentience. Second, it helps to avoid confirmatory bias in the form of giving undue weight to results that are in line with pre-conceived ideas and political views.
No Room For Speciesism In Welfare Considerations, Jennifer Vonk
No Room For Speciesism In Welfare Considerations, Jennifer Vonk
Animal Sentience
Speciesism should play no role in determining welfare outcomes. Cognition may vary within species as well as between species, but broad classifications such as invertebrates are functionally meaningless in this context. Cognition should relate to welfare only to the extent that it relates to the capacity to suffer or to experience pleasure.

Ethical Considerations For Invertebrates, Scarlett R. Howard, Matthew R.E. Symonds
Animal Sentience
Mikhalevich & Powell (2020) have built on the discussion about which species deserve inclusion in animal ethics and welfare considerations. Here, we raise questions concerning the assessment criteria. We ask how to assess different species for their ability to fulfill the criteria, which criteria are most important, how we quantify them (absolute or on a continuum), and how non-animals such as fungi and plants fit into this paradigm.

Lynne Sneddon, PhD
Recent empirical studies have reported evidence that many aquatic species, including fish, cephalopods and crustaceans, have the capacity for nociception and pain, and that their welfare should be taken into consideration. Some sceptics, rejecting the precautionary principle, have denied that any study demonstrates pain or other aspects of sentience in fish. This target article discusses some of the scientific shortcomings of these critiques through a detailed analysis of a study exploring nociception and analgesia in larval zebrafish.
A Risk Assessment And Phylogenetic Approach, Culum Brown
A Risk Assessment And Phylogenetic Approach, Culum Brown
Culum Brown, PhD
The precautionary principal is often invoked when talking about the evidence of sentience in animals, largely because we can never be certain what any animal is thinking or feeling. Birch (2017) offers a preliminary framework for the use of the precautionary principal for animal sentience combining an epistemic rule with a decision rule. I extend this framework by adding an evolutionary phylogentic approach which spreads the burden of proof across broad taxonomic groups and a risk assessment component which magnifies the likely impact by the number of animals involved.

What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy
What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy
Paul McGreevy, PhD
We agree with Chapman & Huffman that human capacities are often assumed to be unique — or attempts are made to demonstrate uniqueness scientifically — in order to justify the exploitation of animals and ecosystems. To extend the argument that human exceptionalism is against our interests, we recommend adopting the One Welfare framework, according to which animal welfare, environmental sustainability and human wellbeing are inseparably linked. Let us distinguish ourselves from other animals by resisting our short- and mid-term Darwinian inclinations, consuming less, reproducing less, and striving for a much longer-term biological fitness for us all.
Unique In Degree Not Kindness, Jennifer Vonk
Unique In Degree Not Kindness, Jennifer Vonk
Animal Sentience
Humans are certainly unique among living species. This is evident in the transformation of human environments and its resulting impact on other animals. However, many of the traits unique to humans are costly as well as adaptive and should certainly not be used to elevate their status above that of other species.
What Should We Do About Sheep? The Role Of Intelligence In Welfare Considerations, Heather Browning
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.
A Behaviorist Approach To Sheep Cognition, Intelligence, And Welfare, Lindsay R. Mehrkam
A Behaviorist Approach To Sheep Cognition, Intelligence, And Welfare, Lindsay R. Mehrkam
Animal Sentience
Marino & Merskin’s review sheds light on the complexity of the mind, learning, and cognition of sheep. Readily observable behavior has value in its own right for promoting the well-being of animals. A behavior-analytic approach can add substantially to the understanding of sheep as individuals as well as their learning capacities. The findings can also be applied to arranging their environments to promote their well-being as well as behavioral change in those responsible for their care and management.

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?

Why Animal Welfarism Continues To Fail, Lori Marino
Why Animal Welfarism Continues To Fail, Lori Marino
Lori Marino, PhD
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.
The Emotional Brain Of Fish, Sonia Rey Planellas
The Emotional Brain Of Fish, Sonia Rey Planellas
Animal Sentience
Woodruff (2017) analyzes structural homologies and functional equivalences between the brains of mammals and fish to understand where sentience and social cognition might reside in teleosts. He compares neuroanatomical, neurophysiological and behavioural correlates. I discuss current advances in the study of fish cognitive abilities and emotions, and advocate an evolutionary approach to the underlying basis of sentience in teleosts.

Brain Processes For “Good” And “Bad” Feelings: How Far Back In Evolution?, Jaak Panksepp
Brain Processes For “Good” And “Bad” Feelings: How Far Back In Evolution?, Jaak Panksepp
Animal Sentience
The question of whether fish can experience pain or any other feelings can only be resolved by neurobiologically targeted experiments. This commentary summarizes why this is essential for resolving scientific debates about consciousness in other animals, and offers specific experiments that need to be done: (i) those that evaluate the rewarding and punishing effects of specific brain regions and systems (for instance, with deep-brain stimulation); (ii) those that evaluate the capacity of animals to regulate their affective states; and (iii) those that have direct implications for human affective feelings, with specific predictions — for instance, the development of new treatments …
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 …
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.
Fish Pain: Would It Change Current Best Practice In The Real World?, B. K. Diggles
Fish Pain: Would It Change Current Best Practice In The Real World?, B. K. Diggles
Animal Sentience
Much of the “fish pain debate” relates to how high the bar for pain should be set. The close phylogenetic affinities of teleosts with cartilaginous fishes which appear to lack nociceptors suggests caution should be applied by those who seek to lower the bar, especially given the equivocal and conflicting nature of the experimental data currently available for teleosts. Nevertheless, even if we assume fish “feel pain,” it is difficult to see how current best practice in aquaculture would change. This is because of the need to avoid stress at all stages of the rearing process to optimize health, growth …

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.

The Applicability Of The Self-Fulfillment Account Of Welfare To Nonhuman Animals, Babies, And Mentally Disabled Humans, Tatjana Visak, Jonathan Balcombe
The Applicability Of The Self-Fulfillment Account Of Welfare To Nonhuman Animals, Babies, And Mentally Disabled Humans, Tatjana Visak, Jonathan Balcombe
Jonathan Balcombe, PhD
In this paper we will argue that generality is a virtue of Haybron’s account of welfare. Indeed, reflecting on the applicability of his theory to nonhuman animals will give us a better understanding of its applicability to humans. We will first focus on self-fulfillment and suggest an interpretation of Haybron’s account according to which the self-fulfillment of an individual consists in the fulfillment of the aspects of the self that are applicable to that particular individual. This makes Haybron’s account of welfare applicable to all sentient beings. Then we will focus on sub-personal nature-fulfillment and argue that the same interpretation …
