Ponderings of science, philosophy, history, society, and many other topics
I recently completed Anil Seth's new book, Being You: A New Science of Consciousness. Seth starts out discussing David Chalmers' hard problem of consciousness, as well as views like physicalism, idealism, panpsychism, and functionalism. Seth is a physicalist, but is suspicious of functionalism. Seth makes a distinction between the hard problem, which he characterizes as … Continue reading Anil Seth’s theory of consciousness
It's been a while since I listed good sources to learn about neuroscience and the brain. I think anyone interested in consciousness and the mind should get a grounding in the basics. It's a bit of work, but the introductory accounts aren't anything unmanageable for someone who can parse philosophically dense material. And it enables … Continue reading Sources of information on neuroscience
(Warning: neuroscience weeds) Some years ago, I reviewed Antonio Damasio's theory of consciousness, based on his book, Self Comes to Mind. (He has a newer book, The Strange Order of Things, which I haven't read yet, so this may not represent his most current views.) In that book, Damasio makes a distinction between two types … Continue reading Perceptions are dispositions all the way down
The other day, when discussing Mark Solms' book, I noted that he is working to create an artificial consciousness, but that he emphasizes that he isn't aiming for intelligence, just the conscious part, as though consciousness and intelligence are unrelated. This seems to fit with his affect centered theory of consciousness, and it matches a … Continue reading Consciousness and intelligence
I've discussed many times how difficult consciousness can be to define. One of the earliest modern definitions, from John Locke, was, "the perception of what passes in a man's own mind." This definition makes consciousness inherently about introspection. But other definitions over the centuries have focused on knowledge in general as well as intentionality, the … Continue reading A perceptual hierarchy of consciousness
I recently finished Mark Solms' new book, The Hidden Spring: A Journey to the Source of Consciousness. There were a few surprises in the book, and it had what I thought were strong and weak points. My first surprise was Solms' embrace of the theories of Sigmund Freud, including psychoanalysis. Freud's reputation has suffered a … Continue reading Mark Solms’ theory of consciousness
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
In the last post, in response to my criticism of Chalmers for relying on the standard but vague "something it is like" definition of phenomenal consciousness, someone pointed out that Chalmers has talked before metaphorically about a movie playing in our head, notably at the beginning of his TED talk on consciousness. I think this … Continue reading The problem with the theater of the mind metaphor
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
