Preface: I agree with pretty much all of what you said. The other day, though, I had washed my hands. I had to be careful because one of my fingers can’t get wet due to an injury. While carefully washing my hand, I noticed that I was “experiencing” wetness all over my hand — to include on portions that were completely dry. I found this rather interesting, that I was experiencing something which I knew to be factually false. I wonder if the difference between processing and experiencing could have something to do with that. I think a lot about this stuff. conscious beings seem to self-produce composite models of the world, from which the world can be effectively navigated. conscious beings seem to also model themselves. This is keenly distinct from self-awareness. I’m referring to a model that helps you balance, walk, know when you’re hot or cold, … conscious beings can have “concepts,” which seem to be recursive and generative. You can’t describe a concept without referring to more concepts. There is no “root” concept. Also, for some reason, it’s often easier to understand what a “concept” is by investigating what it is not. conscious beings seem to be able to compartmentalize composite “concepts” into a singular, singular irreducible concept. Like if I conceptualize a combination of “banana,” “bread,” and “pudding,” I might come up with a brand new experience of “banana bread pudding.” That new experience can be referenced in its own right, and it’s not necessarily reducible back to the concepts which birthed it in the first place. I could go on and on. Sometimes I think it’s ridiculous that I can’t so easily find existing material on this stuff. You seem to be well versed on this topic. Can I ask what your study materials have been?

There’s also the concept of consciousness without memory. What’s that like? Being able to experience the current moment but having no memory of any past experiences - including your experience one second ago. Or here’s a scary thought: what if general anesthesia doesn’t actually switch off consciousness but simply blocks new memories from forming? You could experience the full horror of being awake during surgery but remember none of it. From the perspective of “now,” that would be functionally the same as never having experienced it at all. Then there are those extremely weird recordings from split-brain studies. Back when grand mal seizures were treated by cutting the corpus callosum - the bridge between the two brain hemispheres - to stop the “storm” from spreading. On the surface these patients seemed completely normal after the operation, but some really strange stuff shows up when you start testing them properly. There’s a way you can communicate with each hemisphere independently without the other one knowing. The left hemisphere controls the right side of the body, the right hemisphere the left side. You can flash text on the left side of the visual field (which only the right, non-verbal hemisphere sees), then hand them a pen and let the left hand (controlled by the right hemisphere) answer questions by writing. Turns out that the two halves often don’t agree on things. Ask the right hemisphere what it wants to do for a living and you’ll get a different answer than what the left hemisphere says out loud. Or you can give the right hemisphere a task - “go get a glass of water” - and when you ask the left hemisphere why it did that, it just makes up an explanation. “I was thirsty,” it’ll say, even though the researchers know that’s not true. It genuinely seems like there are two separate consciousnesses running in the same brain at the same time. The big question is: were they there all along, or does the second one only emerge once the connection between them is cut? And yeah, this is all stuff I’ve absorbed from podcasts covering these topics - mostly from Sam Harris. I’m just naturally really curious about the human mind, and I’m pretty experienced with meditation as well, so I probably pay attention to my day-to-day conscious experiences about 1% more than the average person. I’m however not in any way expert on this. It’s not even remotely related to what I do for living.
