Why Do Your 30 Trillion Cells Feel Like a Self?

I first became aware of David Eagleman in 2011 as the author of a little book titled Sum: Forty Tales from the Afterlives. Which led me to his book Incognito: The Secret Lives of the Brain As luck would have it, he gave a lecture later that year at nearby Westminster College (How the Internet Will Save the World: Six Easy Steps to Avert the Collapse of Civilizations) which I found fascinating. So when I discovered his weekly podcast I was quick to check it out and discovered he has done a deep dive into one of my favorite topics: the illusion of the self.

WARNING: These are long. Part 1 is 30 min, Part 2 one hour.

What Is A Thought?

I have been fascinated by this question –and its many answers– for years. Forty-one posts (this makes 42). Additionally, I’m a fan of David Eagleman (tag link below). In the podcdast below he attempts to answer the question, What Is A Thought?

Couple of things about this video I found noteworthy:

  • Dr. Eagleman appears to be speaking extemporaneously. I suppose he could be reading from a prompter but it doesn’t sound/look like it. If not, what an amazing skill.
  • The brief video clips used to illustrate some of the ideas presented appeared to be AI generated. A little over-the-top but effective nonetheless.
  • Where would I have found a clear, coherent presentation by a noted neuroscientist on this topic before YouTube? Certainly not on network or cable TV. A college classroom (if you could afford to go) I suppose.

Thinking about thoughts

I prompted Perplexity to tell me if scientists had determined how many thoughts we think every day. Obviously nobody knows for certain but 6,200 is the number she came up with. As I prepared to include a link to her findings in this post, I discovered I could create a “page” and publish that (somewhere) on Perplexity. While I didn’t write a single word of that page, I guess I get credit for the prompt? (“Curated by smays”)

Looking at the tag cloud on my blog I learned I have posted on the topic of “thoughts” 39 times going back fourteen years. A blog rabbit hole I couldn’t resist. Didn’t read them all but plan to read one each morning for the next month. I did, however, scrape some bits to give you a taste. (Each of these from a different source)

“I’m imagining a technology that doesn’t exist. Yet. A lightweight set of electrodes that monitors my brainwaves and transcribes (transmitted via Bluetooth to my mobile device, let’s say) my thoughts. An advanced version of today’s voice-to-text apps. We get to read that “stream of consciousness” at long last.”

“Thoughts think themselves.” […] “Feelings are, among other things, your brain’s way of labeling the importance of thoughts, and importance determines which thoughts enter consciousness.”

“If I re-google my own email (stored in a cloud) to find out what I said (which I do) or rely on the cloud for my memory, where does my “I” end and the cloud start? If all the images of my life, and all the snippets of my interests, and all of my notes and all my chitchat with friends, and all my choices, and all my recommendations, and all my thoughts, and all my wishes — if all this is sitting somewhere, but nowhere in particular, it changes how I think of myself. […] The cloud is our extended soul. Or, if you prefer, our extended self.”

“The problem is not thoughts themselves but the state of thinking without knowing we are thinking.”

“Even if your life depended on it, you could not spend a full minute free of thought. […] We spend our lives lost in thought. […] Taking oneself to be the thinking of one’s thoughts is a delusion.”

“Look at other people and ask yourself if you are really seeing them or just your thoughts about them. Sometimes our thoughts act like “dream glasses.”

“We often see our thoughts, or someone else’s, instead of seeing what is right in front of us or inside of us.”

“Our minds are just one perception or thought after another, one piled on another. You, the person, is not separate from these thoughts, the thing having them. Rather you just are the collection of these thoughts.”

“Nothing You See is Real”


Wikipedia: “Donald David Hoffman is an American cognitive psychologist and popular science author. He is a professor in the Department of Cognitive Sciences at the University of California, Irvine, with joint appointments in the Department of Philosophy, the Department of Logic and Philosophy of Science, and the School of Computer Science. Hoffman studies consciousness, visual perception and evolutionary psychology using mathematical models and psychophysical experiments.”

Based on years of meditation and lots of reading on the subject of consciousness, I actually get this.

The Kekulé Problem

“The Kekulé Problem” is a 2017 nonfiction essay by writer Cormac McCarthy for the Santa Fe Institute. It was his first published work of nonfiction. He theorizes about the nature of the unconscious mind and its separation from human language. The unconscious, according to McCarthy, “is a machine for operating an animal” and that “all animals have an unconscious.” McCarthy goes on to postulate that language is purely a human cultural creation, and not a biologically determined phenomenon. (Wikipedia)

“You may have read a thousand books and be able to discuss any one of them without remembering a word of the text.”

“The unconscious wants to give guidance to your life in general but it doesn’t care what toothpaste you use.”

“The unconscious seems to know a great deal. What does it know about itself? Does it know that it’s going to die? What does it think about that?”

The essay checked a lot of my boxes: awareness, consciousness, ego, thoughts.
