Whether Invertebrates Are Sentient Matters To Bioethics And Science Policy, Michael L. Woodruff
Whether Invertebrates Are Sentient Matters To Bioethics And Science Policy, Michael L. Woodruff
Animal Sentience
Mikhalevich & Powell provide convincing empirical evidence that at least some invertebrates are sentient and hence should be granted moral status. I agree and argue that functional markers should be the primary indicators of sentience. Neuroanatomical homologies provide only secondary evidence. Consensus regarding the validity of these functional markers will be difficult to achieve. To be effective in practice, functional markers of sentience will have to be tested and accepted species by species to overcome the implicit biases against extending moral status to invertebrates.
Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff
Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff
Animal Sentience
Chapman & Huffman argue that the cognitive differences between humans and nonhuman animals do not make humans superior to animals. I suggest that humans have domain-general cognitive abilities that make them superior in causing uniquely complex changes in the world not caused by any other species. The ability to conceive of and articulate a claim of rights is an example. However, possession of superior cognitive ability does not entitle humans to superior moral status. It is sentience, not cognitive complexity, that is the basis for the assignment of rights and the protections under the law that accompany them.
Thinking Chickens: A Review Of Cognition, Emotion, And Behavior In The Domestic Chicken, Lori Marino
Thinking Chickens: A Review Of Cognition, Emotion, And Behavior In The Domestic Chicken, Lori Marino
Intelligence Collection
Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. At least some birds are now known to be on par with many mammals in terms of their level of intelligence, emotional sophistication, and social interaction. Yet, views of chickens have largely remained unrevised by this new evidence. In this paper, I examine the peer-reviewed scientific data on the leading edge of cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities in …
Fish Intelligence, Sentience And Ethics, Culum Brown
Fish Intelligence, Sentience And Ethics, Culum Brown
Sentience Collection
Fish are one of the most highly utilised vertebrate taxa by humans; they are harvested from wild stocks as part of global fishing industries, grown under intensive aquaculture conditions, are the most common pet and are widely used for scientific research. But fish are seldom afforded the same level of compassion or welfare as warm-blooded vertebrates. Part of the problem is the large gap between people’s perception of fish intelligence and the scientific reality. This is an important issue because public perception guides government policy. The perception of an animal’s intelligence often drives our decision whether or not to include …
Aquatic Animals, Cognitive Ethology, And Ethics: Questions About Sentience And Other Troubling Issues That Lurk In Turbid Water, Marc Bekoff
Sentience Collection
In this general, strongly pro-animal, and somewhat utopian and personal essay, I argue that we owe aquatic animals respect and moral consideration just as we owe respect and moral consideration to all other animal beings, regardless of the taxonomic group to which they belong. In many ways it is more difficult to convince some people of our ethical obligations to numerous aquatic animals because we do not identify or empathize with them as we do with animals with whom we are more familiar or to whom we are more closely related, including those species (usually terrestrial) to whom we refer …
The Changing Concept Of Animal Sentience, Ian J. H. Duncan
The Changing Concept Of Animal Sentience, Ian J. H. Duncan
Sentience Collection
A brief history of the concept of sentience is given. It is pointed out that the idea of sentience, at least in the mammals and birds, was accepted by lay people by the time of the Renaissance and before it was acknowledged by philosophers. It was not until the Enlightenment of the 18th century that philosophers started to accept the notion that animals have feelings. Towards the end of the 19th century, scientists and philosophers had developed a fairly sophisticated concept of sentience. Little consideration was given to sentience by scientists through much of the 20th century due to the …
