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.


Aesthetics And Imagining The Octopus’S Mind, André Krebber, Maike Riedinger, Yvette Watt Jan 2019

Aesthetics And Imagining The Octopus’S Mind, André Krebber, Maike Riedinger, Yvette Watt

Animal Sentience

Several commentators on Mather’s target article discuss the challenges of finding adequate cognitive methods and concepts for accessing the mind and experience of octopuses. Building on Godfrey-Smith’s commentary, we propose aesthetics as a way. The arts provide means to perform what Godfrey-Smith calls an “imaginative leap” to access the experience of octopuses, especially mimesis. We are trying to do this in our current project Okto-Lab. Laboratory for Octopus Aesthetics.


What Is In An Octopus's Mind?, Jennifer Mather Jan 2019

What Is In An Octopus's Mind?, Jennifer Mather

Animal Sentience

It is difficult to imagine what an animal as different from us as the octopus ‘thinks’, but we can make some progress. In the Umwelt or perceptual world of an octopus, what the lateralized monocular eyes perceive is not color but the plane of polarization of light. Information is processed by a bilateral brain but manipulation is done by a radially symmetrical set of eight arms. Octopuses do not self-monitor by vision. Their skin pattern system, used for excellent camouflage, is open loop. The output of the motor system of the eight arms is organized at several levels — brain, …


What And Where Is An Octopus’S Mind?, Jennifer A. Mather Jan 2019

What And Where Is An Octopus’S Mind?, Jennifer A. Mather

Animal Sentience

It is gratifying to see the thorough discussion of whether octopuses have a mind, though perhaps a mind that is different from those of “higher” vertebrates. It stimulates us to look at the welfare of these animals and challenges us to find better ways to test mindfulness and cognition across animals with widely differing natural histories and sensory and motor capacities.


Still Wondering How Flesh Can Feel, Gwen J. Broude Dec 2016

Still Wondering How Flesh Can Feel, Gwen J. Broude

Animal Sentience

Reber believes he has simplified Chalmers’s “hard problem” of consciousness by arguing that subjectivity is an inherent feature of biological forms. His argument rests on the related notions of continuity of mind and gradual accretion of capacities across evolutionary time. These notions need to be defended, not just asserted. Because Reber minimizes the differences in mental faculties among species across evolutionary time, it becomes easier to assert, and perhaps believe, that sentience is already present in early biological forms. The more explicit we are about the differences among these mental faculties and the differences across species, the less persuasive is …


Reber’S Caterpillar Offers No Help, Carl Safina Dec 2016

Reber’S Caterpillar Offers No Help, Carl Safina

Animal Sentience

Reber’s target article “Caterpillars, consciousness and the origins of mind” seems only to shift but not to address the question of where the mind is and how minds occur.



How Could Consciousness Emerge From Adaptive Functioning?, Max Velmans Sep 2016

How Could Consciousness Emerge From Adaptive Functioning?, Max Velmans

Animal Sentience

The sudden appearance of consciousness that Reber posits in creatures with flexible cell walls and motility rather than non-flexible cells walls and no motility involves an evolutionary discontinuity. This kind of “miracle” is required by all “discontinuity” theories of consciousness. To avoid miraculous emergence, one may need to consider continuity theories, which accept that different forms of consciousness and material functioning co-evolve but assume the existence of consciousness to be primal in the way that matter and energy are assumed to be primal in physics.


Bacteria And The Cellular Basis Of Consciousness, Michael L. Woodruff Aug 2016

Bacteria And The Cellular Basis Of Consciousness, Michael L. Woodruff

Animal Sentience

According to Reber’s theory, the Cellular Basis of Consciousness (CBC), sentience originates as bio-sensitivity in unicellular organisms. For this reason, Reber regards sentience as evolutionarily foundational. Many bacteria show chemotaxis and, thus, according to CBC, they are sentient. Analysis of the genetic mechanisms underlying bacterial chemotaxis indicates that sentience has no explanatory power in this case. Genetic analysis also fails to show species continuity underlying bio-sensitivity in bacteria and bio-sensitivity in species with nervous systems, so it does not seem that sentience is evolutionary foundational. CBC is rejected on these grounds.


Caterpillars, Consciousness And The Origins Of Mind, Arthur S. Reber Jul 2016

Caterpillars, Consciousness And The Origins Of Mind, Arthur S. Reber

Animal Sentience

A novel framework for the origins of consciousness and mind, the Cellular Basis of Consciousness (CBC), is presented. The model is based on a simple, perhaps radical axiom: subjectivity is an inherent feature of particular kinds of organic form. Experiential states, including those denoted as "mind" and "consciousness," are present in the most primitive species. The model has several conceptual and empirical virtues, among them: (a) it (re)solves the problem of how minds are created by brains ─ also known as the "Hard Problem" (Chalmers 1995) ─ by revealing that the apparent difficulty results from a category error, (b) it …
