Ethical Considerations For Invertebrates, Scarlett R. Howard, Matthew R.E. Symonds
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.
Sentience In Evolutionary Context, Jon Mallatt, Todd E. Feinberg
Sentience In Evolutionary Context, Jon Mallatt, Todd E. Feinberg
Animal Sentience
We appreciate the goals of Mikhalevich & Powell (M&P) and largely agree with their conclusions but we differ on some of their definitions and terms. Affects (emotional feelings) should be part of sentience. Although the evidence presented for insect sentience is strong, we list some of the counterevidence that should be considered. Our own research supports M&P’s choice of arthropods, cephalopods, and vertebrates as the only sentient organisms with moral status.
Rethinking Rewilding Through Multispecies Justice, Danielle Celermajer
Rethinking Rewilding Through Multispecies Justice, Danielle Celermajer
Animal Sentience
Baker & Winkler’s argument that some humans, especially some Indigenous peoples, neither conceive of themselves as ontologically distinct from nature, nor do they organize their lives as such, is an important one. However, one needs to understand how colonialism and global capitalism have drawn Indigenous peoples and animals into new political economies. The new situation and the constrained opportunities available may have introduced a range of injustices or forms of violence that did not previously exist. This commentary proposes how a multispecies justice lens might assist in evaluating the most just arrangement for all parties, human and non-human.
Conventional Science Will Not Do Justice To Nonhuman Interests: A Fresh Approach Is Required, Becca Franks, Christine Webb, Monica Gagliano, Barbara Smuts
Conventional Science Will Not Do Justice To Nonhuman Interests: A Fresh Approach Is Required, Becca Franks, Christine Webb, Monica Gagliano, Barbara Smuts
Animal Sentience
Treves et al. (2019) make a convincing case that conservation efforts need to go beyond an anthropocentric worldview. Implementing that vision, however, will require human advocates to represent nonhuman interests. Where will the knowledge of those interests come from? How can humans know what is in the best interest of another animal, a plant, or an ecosystem? We discuss how the values embedded in current scientific practices may be ill-suited to representing nonhuman interests and we offer some ideas for correcting these shortcomings.
Preserving Nature For The Benefit Of All Sentient Individuals, Eze Paez
Preserving Nature For The Benefit Of All Sentient Individuals, Eze Paez
Animal Sentience
I agree with Treves et al.’s proposal for a preservation ethics based on the principle that nonhuman well-being is a matter of justice and compassion. In this commentary, I advance two objections. First, only sentient beings, rather than all life, belong in the moral community. Second, given that nature is probably harmful overall for sentient individuals, preserving it for the benefit of future human and nonhuman generations requires us to modify it as far as practicable.
The Wholeness Of Nature, Marthe Kiley-Worthington
The Wholeness Of Nature, Marthe Kiley-Worthington
Animal Sentience
The target article outlines various positions on conservation and preservation but ignores practical considerations of management since there is no wild habitat left. Population controls, either human or nonhuman mammals, are not discussed. The suggestions for legal changes are vague and will require much more thinking about how to integrate animal welfare with wildlife conservation concerns. “Freedoms” as outlined in the human bill of rights might help with decision making for improving animal welfare. Other commentators have made anthropocentric judgements concerning animal welfare, ignoring the importance of developing other ways of seeing and understanding the “multiplicity within unity,” combining empirical …
Conflicts And Triage, Kate E. Lynch, Daniel T. Blumstein
Conflicts And Triage, Kate E. Lynch, Daniel T. Blumstein
Animal Sentience
To represent diverse interests successfully, a strategy for dealing with conflicts is needed. We discuss an approach to maximizing the interests of the greatest number of individuals, present and future.
Just Preservation, Trusteeship And Multispecies Justice, Francisco J. Santiago-Ávila, Adrian Treves, William Lynn
Just Preservation, Trusteeship And Multispecies Justice, Francisco J. Santiago-Ávila, Adrian Treves, William Lynn
Animal Sentience
We are grateful to all the commentators who engaged with our target article. Some commentators have offered important insights into our proposed design and methods for legally intervening on behalf of futurity. Others have focused on theoretical considerations central to our proposal for multispecies justice and trusteeship. All have inspired modifications and further elaboration of our initial proposal. In this Response, we engage with the commentaries, integrating their suggestions, striving for convergence and complementarity, but also discussing points of divergence with our proposed framework where necessary. There is substantial overlap in the points of view of the three co-authors, but …
Exploring Eight-Armed Intelligence Through Film, Tierney M. Thys
Exploring Eight-Armed Intelligence Through Film, Tierney M. Thys
Animal Sentience
Mather (2019) provides a rich overview of the elements underlying octopus cognition and behavioral flexibility. Recently, two remarkable natural history films, My Octopus Teacher and The Octopus in My House have explored intimate human-octopus relationships with a wild (Octopus vulgaris) and a captive octopus (Octopus cyanea) respectively. Both films show rare behaviors that offer observations to test new hypotheses as well as a novel perspective on our own human relationships and place within the natural world. An interview with filmmaker Craig Foster from My Octopus Teacher reveals the profound and transformative power of forming a trusting …
Rewilding And Domestication: Clarifying Terminology, Catia Correia-Caeiro
Rewilding And Domestication: Clarifying Terminology, Catia Correia-Caeiro
Animal Sentience
Baker & Winkler (B&W) describe the state of Asian elephant conservation, raising unique issues, and proposing a direction based on rewilding. The long history and socio-biology of elephants and humans has some parallels with the domestication of dogs (and other species). However, markers of domestication seem absent from elephants. The proper use of terms such as “wild” and “domestic” is crucial in defining the best conservation strategies, and, more important, in attending to the welfare needs of individuals, which can differ between wild and domestic animals. B&W’s target article represents an important starting point for discussion around elephant conservation, but …
Becoming The Good Shepherds, Eze Paez
Becoming The Good Shepherds, Eze Paez
Animal Sentience
It is very important that we clarify what we owe to nonhuman animals. To that end, we need a better understanding of animal cognition and emotion. Marino & Merskin’s target article is a welcome contribution to this project. Sheep, like most other animals, are sentient beings with interests of their own. It is wrong to discriminate against them based on species-membership or cognitive sophistication. We are morally required not to harm them, and to help them have the best possible lives, just as we would be in the case of human beings with similar interests. We must become the good …
Domestication And Cognitive Complexity, David R. Brodbeck, Madeleine I. R. Brodbeck, Keeghan Rosso
Domestication And Cognitive Complexity, David R. Brodbeck, Madeleine I. R. Brodbeck, Keeghan Rosso
Animal Sentience
Marino and Merskin (2019) list a number of tasks that sheep can perform well. As comparative psychologists, we are not surprised by these results. Indeed, many domesticated animal species show similar abilities.
Just Policy Paralysis?, Clare Palmer, Bob Fischer
Just Policy Paralysis?, Clare Palmer, Bob Fischer
Animal Sentience
Treves et al. (2019) argue that policy making should include the interests and well-being of present and future generations of humans and nonhumans. There are deep and abiding conflicts of interest both between and within these groups. Trying to factor in so many considerations is likely to generate political gridlock. The authors need to explain how to avoid this.
The Perfecting Of The Octopus, Ila France Porcher
The Perfecting Of The Octopus, Ila France Porcher
Animal Sentience
Cephalopods split away from the phylogenetic tree about half a billion years ago, and octopus evolution has been accelerated by an extremely low survival rate. This helps explain why this unusual animal presents qualities found in no other. It has a radially organized nervous system with a processing centre for each of its eight tentacles. Yet, although this might suggest that each tentacle has its own centre of consciousness, it remains just one animal, with one mouth to feed, and one life to lose, and it behaves as if it is centrally controlled. Its capacity for a range of intelligent …

Animal Sentience
I present a brief overview of the richness of cephalopod behavioral, neural and cognitive traits.
The Octopus: A Beautiful (But Disorganized) “Mind”, Jon Mallatt
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.
Reconciling Just Preservation, Shelley M. Alexander
Reconciling Just Preservation, Shelley M. Alexander
Animal Sentience
Treves et al.’s target article can play an important role in reconciling the needs of future generations and non-human animals in conservation. Human capacities are adequate for interpreting and defining many non-human animal needs. Worldviews are more complex, however, and conservation science, like the target article itself, suffers from a lack of diversity and inclusiveness. This may pose practical impediments to realizing just preservation.
Applied Cognition Research To Improve Sheep Welfare, Kristina Horback
Applied Cognition Research To Improve Sheep Welfare, Kristina Horback
Animal Sentience
If a change is going to occur in the care and management of domestic sheep, there needs to be a collaborative effort across many disciplines. This review by Marino & Merskin of the literature on cognitive processing in domestic sheep is limited by the inherent bias of the authors, including the impracticable goal of eliminating sheep production. Animal welfare concerns about the management of commercial sheep are valid; however, in order to make a difference, we need to develop an application for this knowledge about cognitive abilities in sheep.
Debunking Human Prejudice And Blindness, Peter J. Li
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 …
What Every Shepherd Knows, Marthe Kiley-Worthington
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 Intelligence Of Sheep, David Gamez
The Intelligence Of Sheep, David Gamez
Animal Sentience
This commentary suggests how recent theories about the predictive brain could help us understand the evidence put forward by Marino & Merskin for intelligence in sheep. I contrast predictive intelligence in sheep with automatic behaviors that do not require intelligence, and I consider the flexibility of sheep intelligence.
The Importance Of Research Applicability, Krista Mclennan
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 …
The Problem Is Not Discourses Of Production; It Is Production Itself, Sean Hermanson
The Problem Is Not Discourses Of Production; It Is Production Itself, Sean Hermanson
Animal Sentience
The mistreatment of sheep is not because of fables, stereotypes, unconscious cultural paradigms, our collective consciousness, anthropocentricism, human arrogance, or our drive to dominate. Nonetheless, protections for sheep used in research and agriculture ought to be strengthened.
Cognitive Dissonance About Sheep Cognition And Consumption, Catia Correia Caeiro
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
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
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.
Anthropocentrism: Practical Remedies Needed, Helen Kopnina
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
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.
Why Cod Don't Like To Sunbathe: Quantity And Quality In The Animal Kingdom, Christoph Jung
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.

Mobilizing Heads And Hearts For Wildlife Conservation, Valérie A. M. Schoof, Simon L'Allier
Animal Sentience
Highlighting the shared evolutionary relationships between humans and animals — and recognizing that all species, including humans, are unique in their own way — may facilitate caring for and conserving animals by tapping into a human emotion: empathy.
