Defining And Exploring Animal Sentience, Andrew N. Rowan, Joyce M. D'Silva Mrs, Ian J.H. Duncan, Nicholas Palmer Jan 2023

Defining And Exploring Animal Sentience, Andrew N. Rowan, Joyce M. D'Silva Mrs, Ian J.H. Duncan, Nicholas Palmer

Animal Sentience

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.


Legal Recognition Of Animal Sentience: The Case For Cautious Optimism, Jane Kotzmann Jan 2022

Legal Recognition Of Animal Sentience: The Case For Cautious Optimism, Jane Kotzmann

Animal Sentience

Rowan et al.’s target article provides a valuable indication of the work that was required to reach the point where animals are recognised as sentient in various laws. To ensure this work was not in vain, the language of sentience needs to be used as a moral currency to demand further cultural change involving greater human respect for animals.


No Need For Certainty In Animal Sentience, Yew Kwang Ng Jan 2022

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.


Sentience And Sentient Minds, John Anthony Webster Jan 2022

Sentience And Sentient Minds, John Anthony Webster

Animal Sentience

My commentary builds on Rowan et al.’s (2022) comprehensive review to address the question ‘what do we mean by sentience?’ It suggests how we might recognise degrees of sentience within the animal kingdom, ranging from primitive sensations such as hunger and pain to more complex emotions that determine quality of life.


Zones Of Precaution, Jonathan Birch Jul 2020

Zones Of Precaution, Jonathan Birch

Animal Sentience

My commentary focusses on Mikhalevich & Powell’s criticisms of the Animal Sentience Precautionary Principle. I emphasize the pragmatic nature of my rationale for proposing that, rather than extending the scope of animal welfare protection on a species-by-species basis, we should be willing to protect entire Linnaean orders on the basis of evidence from a single species.


Animal Sentience Is Not Enough To Motivate Conservation, Irene M. Pepperberg Jan 2019

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.


Refining The Precautionary Framework, Jonathan Birch Jan 2017

Refining The Precautionary Framework, Jonathan Birch

Animal Sentience

Most of the commentators so far agree that the precautionary principle can be usefully applied to the question of animal sentience. I consider various ways of refining my proposals in light of the suggestions. I amend BAR to implement C. Brown’s suggestion that the scope of animal welfare law should be extensible by phylogenetic inference from orders in which credible indicators of sentience are found. In response to C. Brown, Mallatt, and Woodruff, I amend ACT to allow that a single credible indicator may sometimes call for urgent further investigation rather than immediate protection. In response …


Animal Sentience And The Precautionary Principle, Jonathan Birch Jan 2017

Animal Sentience And The Precautionary Principle, Jonathan Birch

Animal Sentience

In debates about animal sentience, the precautionary principle is often invoked. The idea is that when the evidence of sentience is inconclusive, we should “give the animal the benefit of the doubt” or “err on the side of caution” in formulating animal protection legislation. Yet there remains confusion as to whether it is appropriate to apply the precautionary principle in this context, and, if so, what “applying the precautionary principle” means in practice regarding the burden of proof for animal sentience. Here I construct a version of the precautionary principle tailored to the question of animal sentience together with a …


A Preliminary Investigation Into The Welfare Of Lobsters In The Uk, Gemma Carder Jan 2017

A Preliminary Investigation Into The Welfare Of Lobsters In The Uk, Gemma Carder

Animal Sentience

The welfare of invertebrates is overlooked and their needs are not understood. It is assumed that they do not experience pain and suffering. Studies on decapod crustaceans challenge this assumption. Research has focused on distinguishing between nociception (the ability to detect a harmful stimulus and to react to it reflexively) and pain (an aversive feeling or emotional experience). Findings indicate that decapod crustaceans can experience pain, which supports a case for protecting their welfare. I have investigated the current husbandry conditions of a globally consumed decapod crustacean, the lobster, as housed in tanks inside food outlets in the UK. Housing …


Beginnings: Physics, Sentience And Luca, Carolyn A. Ristau Sep 2016

Beginnings: Physics, Sentience And Luca, Carolyn A. Ristau

Animal Sentience

According to Reber’s model, Cellular Basis of Consciousness (CBC), sentience had its origins in a unicellular organism and is an inherent property of living, mobile organic forms. He argues by analogy to basic physical forces which he considers to be inherent properties of matter; I suggest that they are instead the stuff of scientific investigation in physics. I find no convincing argument that sentience had to begin in endogenously mobile cells, a criterial attribute of the originator cell(s)for sentience according to CBC. Non-endogenously mobile cells, (i.e., plants or precursors) in a moving environment would suffice. Despite my concerns and the …


Anticipatory Grief, Tara Fox Hall Jan 2016

Anticipatory Grief, Tara Fox Hall

Animal Sentience

This commentary reviews Barbara King’s How Animals Grieve, delving into the controversial topic of the status of animals in our society, as well as the key difference between human and non-human grief: the ability to anticipate death.



Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke Jan 2016

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.


What’S The Common Sense Of Just Some Improvement Of Some Welfare For Some Animals?, Liv Baker Jan 2016

What’S The Common Sense Of Just Some Improvement Of Some Welfare For Some Animals?, Liv Baker

Animal Sentience

The goal of Animal Welfare Science to reduce animal suffering is commendable but too modest: Suffering animals need and deserve far more.
