Pain Sentience Criteria And Their Grading, Eva Jablonka, Simona Ginsburg

Animal Sentience

On the basis of the target article by Crump and colleagues, we suggest a more parsimonious scheme for evaluating the evidence for sentience. Since some of the criteria used by Crump et al. are not independent and some are uninformative we exclude some criteria and amalgamate others. We propose that evidence of flexible learning and prioritization, in conjunction with relevant data on brain organization, is sufficient for assigning pain-sentience to an animal and we suggest a scoring scheme based on four criteria.

Truly Minimal Criteria For Animal Sentience, Mark Solms

Animal Sentience

The criteria for determining animal sentience proposed in the target article are sensible but they lack an explicit functional justification for the focus on pain. This commentary provides an abbreviated account of the most basic functional principles that underpin animal sentience and articulates some minimal criteria for determining its presence.

Crustacean Pain, Michael Tye

Animal Sentience

This commentary discusses the target article’s methodology, the relevance of the claim that crustaceans lack a neocortex to the thesis that they feel pain, and the evaluation of the results of some trade-off experiments done with hermit crabs.

No Need For Certainty In Animal Sentience, Yew Kwang Ng

Animal Sentience

This commentary supports Crump et al.’s (2022) point that where risks to welfare are severe, strong evidence of sentience is sufficient to warrant protecting welfare. Crump et al.’s eight criteria for sentience are also useful. Flexible decision-making (5) and flexible behaviour (6) are consistent with Ng (1995). The concession that the “no-need-for-sentience” proposition is unnecessary also strengthens the importance of the target article’s conclusions.

What Might Decapod Sentience Mean For Policy, Practice, And Public?, Richard Gorman

Animal Sentience

Crump et al. provide eight criteria for evaluating sentience in decapods, with scope for for application to other taxa. Their work has attracted the interest of policymakers. This commentary discusses the limitations of conceptual and legal acknowledgement of sentience in chainging practice and public attitudes. More work is needed. Social science may be able to help.

Fine-Tuning The Criteria For Inferring Sentience, Culum Brown

Animal Sentience

“Sentience” means the capacity to feel, and feelings are private affairs. Sentience is hence extremely difficult to quantify in nonhuman animals. We have no direct means of determining whether an animal is sentient. Thus we rely on a series of indirect measures or criteria which collectively provide some level of confidence about the probability that an animal is sentient. Crump et al. propose a modified framework based on 8 criteria for estimating the likelihood of sentience in a target taxon. Whereas I very much like their proposed framework, I would suggest a couple of amendments that may improve it further: …

Generalizing Frameworks For Sentience Beyond Natural Species, Michael Levin

Animal Sentience

Crump et al. (2022) offer a well-argued example of an essential development: a rigorous framework for assessing sentience from the perspective of moral concern over an agent’s welfare. Current and forthcoming developments in bioengineering, synthetic morphology, artificial intelligence, biorobotics, and exobiology necessitate an expansion and generalization of this effort. Verbal reports (the Turing Test) and homology to human brains are utterly inadequate criteria for assessing the status of novel, unconventional agents that offer no familiar touchstone of phylogeny or anatomy. We must develop principled approaches to evaluating the sentience of (and thus, our responsibility to) beings of unfamiliar provenance and …

Sentience In Decapods: An Open Question, Mark Briffa

Animal Sentience

Crump et al.’s framework is a powerful tool designed to assist decisions on the ethical treatment of decapod crustaceans. However, the question of whether decapods are sentient (i.e., whether they feel), remains open, perhaps indefinitely. More optimistically, we might design experiments that distinguish among different levels of awareness, sometimes viewed as components of sentience. We should strike a balance between assuming that all organisms are sentient and making unnecessary anatomical assumptions about sentience. Refining current experiments may provide concrete insights about awareness in Decapoda and other taxa.

Does The Sentience Framework Imply All Animals Are Sentient?, Kristin Andrews

Animal Sentience

The eight criteria proposed in Crump et al.’s framework for evaluating pain sentience in decapod crustaceans are just the tip of the iceberg when it comes to markers that could increase confidence in an animal’s sentience more generally. Some of the commentaries have already pointed out that pain is only one kind of sentience (Souza Valente). It has also already been pointed out that there are other criteria for pain that could be usefully added to the framework’s eight (Burrell). This expansive thinking about criteria that can be used to increase confidence in sentience raisess the question: in an expansive …

Distinguishing Epistemic And Moral Grounds For Legal Protection, Carlos Montemayor

Animal Sentience

The criteria proposed by Crump et al. are based on various cognitive roles associated with sentience. A subset of them may be sufficient for certain kinds of welfare, but the presence of all of them should be considered as clearly sufficient for substantial kinds of legal protection based on their relation to capacities that we consider essential for moral standing in human beings.

Unconscious Humans, Autonomous Machines And The Difficulty Of Knowing Which Animals Are Sentient, Marian Stamp Dawkins

Animal Sentience

The framework proposed by Crump et al. still leaves much doubt about whether invertebrates such as crabs are sentient. For example, many complex behaviours - even in humans - occur without sentience. Also, simple machines could easily meet all of Crump et al.’s eight proposed criteria for sentience. Acknowledging the limitations of what we currently know about sentience is important both for formulating legislation correctly and for advancing scientific understanding of this most puzzling of biological phenomena.

Sentience Criteria To Persuade The Reasonable Sceptic, Patrick Butlin

Animal Sentience

When presented with evidence that Crump et al.’s criteria are satisfied for the animals in some taxon, a sceptic could reasonably continue to suspend judgement about whether those animals are sentient. This is because the criteria refer to abilities which are associated with sentience in humans, but it is not clear that sentience is necessary for these abilities. The criteria could be strengthed by requiring evidence of a contrast in performance between cases in which information is carried by felt and unfelt states.

The Right To Reproduce, Carolyn Mcleod

Philosophy Publications

The reproductive rights of women have been a central topic in feminist bioethics. The focus has been predominantly on the right not to reproduce, and so not to be subject to pronatalist social forces that make motherhood compulsory for women. That is the case despite many women and other members of marginalized groups experiencing anti-natalism, or in other words, social pressure to avoid biological reproduction. For these groups, the right to reproduce is as important, if not more important, than the right not to reproduce. This chapter concentrates on the right to reproduce and considers what form it should take …

Phenomenological Exploration Of Followers’ Lived Experiences And Their Perception Of Ethical Leadership, Saad R. Maklad

Walden Dissertations and Doctoral Studies

The purpose of this phenomenological qualitative study was to explore the lived experiences of followers under unethical leadership in private and public organizations in the United States. Data collection involved interviewing 20 participants from private or public U.S. organizations with open-ended interview question. Participant selection was limited to followers and frontline employees who directly contact stakeholders. Utilitarianism, Adams’s equity theory, social learning theory, stakeholder theory, and Eudaimonia were the conceptual frameworks used to guide this study. The data analysis process in this phenomenological study consisted of using the two-cycle analysis and the modified Stevick-Colaizzi-Keen method. The findings demonstrated eight overarching …

Abraham Lincoln: Thoughts On Slavery And Racial Equality, Abraham Scofield

OUR Journal: ODU Undergraduate Research Journal

Looking at the political thought of Abraham Lincoln, two major themes arise: slavery and racial equality. Development of his thought on these subjects spanned his entire life and is revealed through his speeches, public statements, and written works. With the sheer amount of thought that Lincoln dedicated to these subjects, it can be difficult to decipher where he truly stood on these issues. To come to a more concrete understanding of Lincoln’s thought regarding these subjects, this article offers multiple interpretations of each of these themes. Concerning Lincoln’s thought on slavery, three interpretations arise: the Anti-Expansion interpretation, the Moral Opposition …

Decapod Sentience: Broadening The Framework, Cecilia De Souza Valente

Animal Sentience

A framework for studying sentience in decapods is of great value, but how high a cost (in suffering) to each individual decapod (or any animal) is warranted for collecting scientific evidence of sentience? The lack of evidence for some of the target article’s proposed criteria surely results from the fact that research is focused mainly on biomedical studies, ecotoxicology, and commercial production, with decapod sentience and welfare seen as only a secondary research topic. I draw attention also to the possibility of a wider framework that includes all felt experiences, from suffering to pleasure.

Sentience In Decapods: Difficulties To Surmount, Michael L. Woodruff

Animal Sentience

In the target article Crump et al. present 8 criteria to assess whether decapods experience pain. Four of these -- sensory integration, motivational trade-offs, flexible self-protection, and associative learning -- could be used to assess sentience in general. In this commentary I discuss difficulties with using these criteria to provide evidence of sentience in decapods, particularly if this evidence is to change public opinion and policies. These difficulties are lack of evidence, the potential to eventually explain the neurobiological basis of the behaviors chosen as criteria, thereby eliminating any explanatory work for sentience, and the reluctance to bring animals that …

Pain In Pleocyemata, But Not In Dendrobranchiata?, Gary Comstock

Animal Sentience

Crump et al.’s contribution to assessing whether decapods feel pain raises an important question: Is pain distributed unevenly across the order? The case for pain appears stronger in Pleocyemata than in Dendrobranchiata. Some studies report pain avoidance behaviors in Dendrobranchiata (Penaeidae) shrimp, but further studies are needed to determine whether the chemicals used are acting as analgesics to relieve pain, or as soporifics to reduce overall alertness. If the latter, the most farmed shrimp species may not require the same level of protection as crabs, crayfish, and lobsters.

Sentience As Part Of Emotional Lives, Frans B. M. De Waal

Animal Sentience

It is high time to explore the sentience of invertebrate animals, but this topic cannot be discussed without also exploring their emotional lives, including positive emotions. Sentience probably evolved to allow the regulation of emotions by endowing them with feelings.

Decapod Sentience: Promising Framework And Evidence, Jon Mallatt, Todd E. Feinberg Md

Animal Sentience

Strong points of the target article by Crump et al. are that it offers clear criteria for judging whether decapods are sentient, an effective semi-quantitative grading system for this purpose, and an astute, critical review of the literature. It concludes plausibly that major subgroups of decapods are sentient. A minor problem is that it includes classical, Pavlovian learning as a marker of sentience along with the more valid marker of complex (e.g., operant) learning. Another minor problem is that it does not distinguish results that are negative because of likely absence of sentience from results that are negative because they …

Decapods As Food, Companions And Research Animals: Legal Impact Of Ascribing Sentience, Jonathan J. Cooper, Ambrose Tinarwo, Beth A. Ventura

Animal Sentience

This commentary provides an overview of the practical implications of attributing sentience to protect decapods as food, companion and research animals in the UK context. Recognising their capacity to suffer has implications for humane slaughter in farming and fishing sectors. It should also place a greater duty of care on owners of captive decapods, considering their needs and avoiding unnecessary suffering. The recognition of decapod sentience should also have an impact on their protection as research animals, although research with a potential to cause suffering may be needed to better understand decapods’ capacity to suffer.

A Framework For Evaluating Evidence Of Pain In Animals, Matilda Gibbons, Lars Chittka

Animal Sentience

Crump et al. define eight criteria indicating sentience in animals, with a focus on pain. Here, we point out the risk of false negative or false positive diagnoses of pain. Criteria of different levels of inclusivity are useful for using the precautionary principle in animal welfare considerations, and for more formal scientific evidence of pain. We suggest tightening the criteria -- from more general evidence of sentience to pain alone -- because crucial evidence for animal welfare decisions might otherwise be missed for animals subjected to invasive and injurious procedures.

Pros And Cons Of A Framework For Evaluating Potential Pain In Decapods, Robert W. Elwood

Animal Sentience

The rigorous framework for research into potential pain in decapods was successful in allowing legislators in the United Kingdom to evaluate a complex scientific issue. However, it might produce problems for research. I discuss doubts about the usefulness of the eight criteria. Some have yet to receive any investigation and others do not allow much inference about pain. In addition, some existing studies are not covered in the framework. Most worrying, however, is the potential for stifling future research of novel areas that are excluded from the framework.

Integrating Evolution Into The Study Of Animal Sentience, Walter Veit

Animal Sentience

Like many others, I see Crump et al. (2022) as a milestone for improving upon previous guidelines and for extending their framework to decapod crustaceans. Their proposal would benefit from a firm evolutionary foundation by adding the comparative measurement of life-history complexity as a ninth criterion for attributing sentience to nonhuman animals.

Animal Sentience Research: Synthesis And Proposals, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch

Animal Sentience

Most commentaries on our target article broadly support our approach to evaluating evidence of animal sentience. In this Response, we clarify the framework’s purpose and address criticisms of our criteria. A recurring theme is that a framework to synthesise current evidence of sentience is not the same as an agenda for future directions in animal sentience research. Although future directions are valuable, our framework aims to evaluate existing evidence and inform animal welfare legislation.

Abortion And The Personhood Assumption: A New Defense Of Abortion On The Basis Of Self-Defense, Timothy Kirschenheiter

Wayne State University Dissertations

In this essay, I offer a new defense of abortion. I argue that even if we assume that the fetus is a person with full moral rights abortion is still generally morally permissible. For this argument, I rely on the concept of self-defense, arguing that abortion is morally permissible as a self-defensive action.

In Chapter II, I motivate the personhood assumption by finding and defending the strongest version of Don Marquis’s Future-Like-Ours Argument.

In Chapter III, I argue for the rejection of responsibility arguments in favor of the moral permissibility of abortion – the sort of arguments offered by Judith …

Why Do Rich People Not Retire?, Xiya Li

Scripps Senior Theses

Work and leisure are central to the human condition. Scholars from many fields have tried to understand why Americans work so much. Many people believe that when they have enough money, they will retire. However, many people are not willing to retire even if they have enough money to do so. Most people who do not have enough money to retire do not even get any amount of leisure from their jobs. If the view that enough money directly leads to retirement is wrong, then it is time to reconsider using this logic to think of the possibility of retiring. …

An Exploration Of Secular And Christian Political Thought, Elizabeth Bradley

Undergraduate Honors Theses

Through the evaluation and comparison of Machiavellian, Nietzschean, and Christian political thought, this thesis argues that Christian thinkers effectively meet the challenges posed to them by Modern philosophers. Modern philosophers reject the teaching that ethical principles have a transcendent origin in God and instead believe that morality is merely a matter of human convention. Christian philosophy was once dominant in influencing political thought. Modern thinkers such as Machiavelli and Nietzsche wrote with the express purpose of challenging and replacing Christian thought. The Christian political tradition promotes more noble qualities in leaders than the modern philosophies which proposed to challenge it. …

Equality And Justice In Aristotle's Theory Of Friendship, Mark Christopher Brennan

Legacy Theses & Dissertations (2009 - 2024)

In this dissertation, I offer an interpretation of Aristotle’s account of friendship thatemphasizes the importance of fairness in understanding the connection that he draws between friendship and justice. Many contemporary interpretations of Aristotle conclude either that the connection between friendship and justice is primarily relevant in the context of political friendship or is primarily a concern for friendships between virtuous individuals. Such interpretations, however, tend to diminish the importance of friendships on account of usefulness and pleasure in Aristotle’s account, as well as the importance of friendships in associations other than the political association.
