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

A perceptual hierarchy of consciousness
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
Stimulating the prefrontal cortex
(Warning: neuroscience weeds) This is an interesting study getting attention on social media: Does the Prefrontal Cortex Play an Essential Role in Consciousness? Insights from Intracranial Electrical Stimulation of the Human Brain. Ned Block is one of the authors. (Warning: paywalled, but you might have luck here.) The study looks at data from epileptic patients … Continue reading Stimulating the prefrontal cortex
Hierarchy of consciousness, January 2021 edition
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
Mind uploading and the philosophy of self
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
The dual nature of affects
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
The problem with the theater of the mind metaphor
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
Consciousness and moral status
This talk by David Chalmers on the relationship between consciousness and moral status is pretty interesting. You don't have to watch the video to follow this post, but it's in response to arguments he makes in the talk. The video is 75 minutes but the talk only lasts about 50 minutes with a Q&A afterward. … Continue reading Consciousness and moral status
The unproductive search for simple solutions to consciousness
(Warning: neuroscience weeds) Earlier this year I discussed Victor Lamme's theory of consciousness, that phenomenal experience is recurrent neural processing, that is, neural signalling that happens in loops, from lower layers to higher layers and back, or more broadly from region to region and back. In his papers, Lamme notes that recurrent processing is an … Continue reading The unproductive search for simple solutions to consciousness
The problem with Mary’s room
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
