Ponderings of science, philosophy, history, society, and many other topics
(Warning: neuroscience weeds) I've discussed global workspace theories (GWT) before, the idea that consciousness is content making it into a global workspace available to a vast array of specialty processes. More specifically, through a neural competitive process, the content excites key hub areas, which then broadcast it to the rest of the specialty systems throughout … Continue reading The location of the global workspace
I often say that consciousness lies in the eye of the beholder, a notion that many dislike and often push back against. To be clear, I do think that for any precise definition of "consciousness", there is a fact of the matter about whether it exists and what has it. Many respond by offering up … Continue reading Hierarchy of consciousness, January 2021 edition
This video does a pretty good job at outlining the idea and stark challenges with mind uploading. (Watching it isn't necessary to understand this post, unless you're completely unfamiliar with the idea. It's 14 minutes long, although the last few minutes are an advertisement.) https://www.youtube.com/watch?v=4b33NTAuF5E Kurzgesagt: Can You Upload Your Mind & Live Forever I'm … Continue reading Mind uploading and the philosophy of self
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
For some reason, Mary's room has been garnering attention lately. This TED Ed video on it was shared on Aeon's site this week. https://www.youtube.com/watch?v=mGYmiQkah4o The wording of the actual thought experiment is important, so quoting Frank Jackson's words (via the Wikipedia article on the knowledge argument): Mary is a brilliant scientist who is, for whatever reason, … Continue reading The problem with Mary’s room
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
When I was very young, the top of my feet started itching, so I started scratching. The itching continued for weeks and months, with me constantly scratching. My poor mother, seeing my red and scratched feet, implored me to stop. But the itching was relentless and I was maybe five or six, so I kept … Continue reading The complex composition of pain
A preprint came up a few times in my feeds, titled: Falsification and consciousness. The paper argues that all the major scientific theories of consciousness are either already falsified or unfalsifiable. One neuroscientist, Ryota Kanai, calls it a mathematical proof of the hard problem. Based on that description, it was hard to resist looking at … Continue reading The substitution argument
(Warning: consciousness theory weeds.) A new paper in the journal Cognitive Neuroscience: Hard criteria for empirical theories of consciousness, takes a shot at proposing criteria for assessing scientific theories of consciousness. The authors make clear at the beginning that they're aiming their criteria at empirical theories, rather than metaphysical ones. So they make no attempt … Continue reading Hard criteria for theories of consciousness?
It's pretty nice to see Kurzgesagt finally continuing its "Big Questions of Life and the Universe" series. I shared the first part on consciousness over a year go. The series is funded by the Templeton Foundation, which I know many people have issues with, but so far the content has been reasonably scientific. https://www.youtube.com/watch?v=ck4RGeoHFko As … Continue reading Kurzgesagt on intelligence, and prospects for engineered intelligence
