Ponderings of science, philosophy, history, society, and many other topics
I'm currently reading Jonathan Birch's The Edge of Sentience, a book focusing on the boundary between systems that can feel pleasure or pain, and those that can't, and the related ethics. While this is a subject I'm interested in, I'm leery of the activism the animal portions of it attract. I have nothing in particular … Continue reading The semantic indeterminacy of sentience
Henry Shevlin has an interesting paper from 2021 in Mind & Language that just went open access: Non-human consciousness and the specificity problem: A modest theoretical proposal. Shevlin discusses the problem of applying cognitive theories of consciousness, developed within the context of human psychology, to non-human systems, such as animals or artificial systems. For example, … Continue reading The specificity problem
When writing about the mind and consciousness, and how it exists in material systems, many of us resort to functional hierarchies. (Mine typically start with physical interaction and work all the way up to self reflection.) Ogi Ogas and Sai Gaddam have a similar idea, and have written a whole book on it: Journey of … Continue reading From molecule minds to superminds
Last week, Science News had an article about the difficulty of studying animal emotions, on understanding what an animal in a particular situation is really feeling. It's an interesting article, although not one with much new information for many of you. However, I want to focus on one point raised by one of the researchers … Continue reading The benefits of functionalism for animal welfare
Daniel Issing has an interesting article at Quillette on the hard problems of vegetarianism. Vegetarianism, and its more pure form, veganism, are often seen as the obvious moral thing we should all be doing, but that most of us aren't. Issing, himself a vegetarian, explores the messy details that make this a more complicated proposition … Continue reading The scope of animal wellbeing
The recent news reports that cuttlefish are able to pass the marshmallow test are interesting. The classic marshmallow test involved giving a young child a marshmallow but promising them a second one if they could hold off eating the first for 15 minutes. The kid was then left alone in a room with the first … Continue reading The marshmallow test and conscious feeling
Mark Solms is coming out with a book on consciousness, which he discusses in a blog post. Solms sees the key to understanding consciousness as affects, specifically feelings, such as hunger, fear, pain, anger, etc. In his view, the failure of science to explain the hard problem of consciousness lies in its failure to focus … Continue reading The dual nature of affects
Last week, Science Magazine published an interesting study on bird consciousness: A neural correlate of sensory consciousness in a corvid bird. The study conducted an experiment where crows were trained to respond to a sensory stimulus. The stimulus itself could be at the threshold of perceptibility, above that threshold, or missing. After the stimulus (or … Continue reading The consciousness of crows
Jonathan Birch has an interesting paper in Noûs: The search for invertebrate consciousness. Birch notes that there is no consensus on whether any invertebrates are conscious, and no agreement on a methodology for establishing whether they are. He starts off assessing the difficulties of applying many human centric theories, such as global workspace, which don't … Continue reading The facilitation hypothesis
The journal, Trends in Cognitive Science, has an interesting paper up: Dimensions of Animal Consciousness. After noting the current consensus that some form of consciousness is present in at least mammals, birds, and cephalopods, it looks at how to evaluate it in various species. The authors take the position that consciousness can be present in … Continue reading Dimensions of animal consciousness
