Limits To Sentience, Donald M. Broom
Limits To Sentience, Donald M. Broom
Animal Sentience
There are many parallels between cellular function in animals and plants. Plants can have complex interactions with their environments. But they lack a central nervous system, which is a prerequisite for sentience (the capacity to feel). In my view the suggestion that plants are sentient is not only empirically incorrect but potentially harmful to the efforts to protect the welfare of sentient beings.
Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters
Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters
Animal Sentience
Evidence for sentience in animals distantly related to humans is often sought in observations of behavioral and neural responses to noxious stimuli that would be painful in humans. Most proposed criteria for painful sentience in “lower” animals such as decapod crustaceans have no necessary links to the affective (“suffering”) component of pain. The best evidence for painful affect in animals is learned aversion to stimuli associated with noxious experience, and conditioned preference for contexts associated with relief from aversive consequences of noxious experience, as expressed in voluntary behavior. Such evidence is currently lacking for any invertebrate except octopus.
Why The Recognition Of Sentience Is So Important For Animal Welfare, Mark Jones
Why The Recognition Of Sentience Is So Important For Animal Welfare, Mark Jones
Animal Sentience
Rowan et al. (2022) provide a useful summary of the history and development of the philosophical, public, and legal recognition of animal sentience and its importance in improving the welfare of animals. Here I argue for the incorporation of the precautionary principle in sentience recognition, and the wider significance of sentience recognition to the current climate, biodiversity and human health crises.
Extending Animal Welfare Science To Include Wild Animals, Walter Veit, Heather Browning
Extending Animal Welfare Science To Include Wild Animals, Walter Veit, Heather Browning
Animal Sentience
Ng’s (2016) target article built on his earlier work advocating a science of welfare biology (Ng 1995). Although there were problems with the models proposed in Ng’s original paper regarding the balance of pleasure and suffering for wild animals, his call for a science of wild animal welfare was a sound one. This does not require a new discipline but just an extension of the existing frameworks and methods of animal welfare science to include wild animals.
Intensive Animal Farming Conditions Are A Major Threat To Global Health, Cynthia Schuck-Paim
Intensive Animal Farming Conditions Are A Major Threat To Global Health, Cynthia Schuck-Paim
Animal Sentience
Wiebers & Feigin accurately propose that reducing the risks posed by infectious disease outbreaks and other global health challenges will depend critically on transitioning away from intensive animal farming practices. Creating the right incentive structure for this transition to happen is one of the great challenges in the years to come, but a much-needed step to ensure the health and well-being of current and future generations.
Brain Complexity, Sentience And Welfare, Donald M. Broom
Brain Complexity, Sentience And Welfare, Donald M. Broom
Animal Sentience
Neither sentience nor moral standing is confined to animals with large or human-like brains. Invertebrates deserve moral consideration. Definition of terms clarifies the relationship between sentience and welfare. All animals have welfare but humans give more protection to sentient animals. Humans should be less human-centred.
The Necessity Of Human Attitude Change And Methods Of Avoiding Pandemics, Donald M. Broom
The Necessity Of Human Attitude Change And Methods Of Avoiding Pandemics, Donald M. Broom
Animal Sentience
Humans share their biology with other animals and in each of their actions should consider the consequences for all life. A series of measures can be taken by governments and individuals that would minimise inter-specific transfer of pathogens from wildlife and reduce the development of antimicrobial resistance.
Utilitarianism Generalized To Include Animals, Yew-Kwang Ng
Utilitarianism Generalized To Include Animals, Yew-Kwang Ng
Animal Sentience
In response to the seventeen commentaries to date on my target article on reducing animal suffering, I propose that the term “welfarism” (when used pejoratively by animal advocates) should be qualified as “anthropocentric welfarism” so as to leave “welfarism” simpliciter to be used in its generic sense of efforts to improve conditions for those who need it. Welfarism in this benign sense — even in its specific utilitarian form (maximizing the sum total of net welfare) with long-term future effects and effects on others (including animals) appropriately taken into account — should be unobjectionable (even if not considered sufficient by …
