    I really enjoyed this conversation with Karl. From the vodka and wine in the background to the mathematics of existence, life, intelligence, and consciousness, this was a truly fascinating experience. Here's the outline:
    0:00 - Introduction
    1:50 - How much of the human brain do we understand?
    5:53 - Most beautiful characteristic of the human brain
    10:43 - Brain imaging
    20:38 - Deep structure
    21:23 - History of brain imaging
    32:31 - Neuralink and brain-computer interfaces
    43:05 - Free energy principle
    1:24:29 - Meaning of life

    Certainly one of the best, if not the best, of Lex's podcasts. Karl Friston introduced quite a few concepts that I would not have (and never could have) come up with on my own. Always amazed that Lex seems to absorb the ideas his guests present and come up so quickly with question that keep the conversation going.

      AFAIK this idea was very clearly expressed in the book _"I of the Vortex: From Neurons to Self"_ by neuroscientist Rodolfo Llinas about 20 years ago.

    Karl Friston is a surfer. I know because I am a surfer and I can't help but get the sense of surfing while comprehending all this.

The paradigmatic impact of what he's saying can't be overstated.

Where other thinkers have to rely on much cruder, headier symbols, free energy has a clean-ness to it that's fantastic. Also a very polite, calm and charming person, which in my mind always lends credence to theorists. I feel lke his way of thinking makes him a comfortable and approachable human being

    This taps n BEAUTIFULLY to Jayne;s bicamerality breakdown (the left/right are, after all, at least proto-selves) and McGhilchrist's hemispheric observations about the 'battle' between the hemispheres (more kindly: 'interaction', or 'balance') as a phase of the overall system in developing a single coherent Self.

    Commenting on the question when does the collection of grains of sand becomes a pile. For me it seems reasonable that once you are unable to tell how many grains are there without manipulating them physically, you can call it a pile. If you can say the number of grains by looking but not touching them, it is the collection of individual grains.

    • @Demosophist
      @Demosophist 4 роки тому

      This expresses a general preference I have, which may not reflect reality at all. That is the notion that research is being directed by human preferences, so possibly by preferences that are counter to my human interests. But the possibility is that none of this is really directed by human ingenuity any longer because we've reached the boundaries of the extension of the physical/chemical body, and what's actually happening is more like satisfying the curiosity and interest of the non-physical *about* the physical. In other words this is all about the extension of the non-physical "entities" back into the physical and following the threads of our history of technological extension. No one is going to ever propose this in academia, so it's not something one need worry about.

    • @Demosophist
      @Demosophist 4 роки тому

      I was wrong. Professor Friston seems to be onto this, at least in part. The notion that the extension *out* has reached a limit where first and second nature have merged, after which the directionality of extension reverses back through the extensions to alter the organism in the direction of the eternal probably hasn't occurred to him... *yet*.

    • @Demosophist

      Let me just add this: the Robinson Crusoe conjecture seems to me incomplete. It's not enough that there are other copies of me. They have to be sufficiently different from me that they compel an inference of an "I" versus a "thou." There are also, obviously, gradients of this. Julian Jaynes' conjecture was essentially that writing, and especially phonetic writing, interfered with the voice of the interior god of the right brain sufficiently to cause a recognition of otherness as the Voice went silent. But this is consistent with the notion that "self" is an inference, even though it's slightly more complicated. It's that role of the right brain, or of the grammatical and rhetorical capacity that was compelled by the interference of dialectic to infer a self separate from the gen pop.

    I was glad to hear that brain implants are difficult to implement. To me a non-intrusive solution seems much better, such as detecting electromagnetic fields with external devices similar to earbuds and smart glasses. Machine learning could be trained to interpret the electromagnetic fields at a very high abstraction level.

    1:20:45 Holy cow! Isn't that equivalent to Hegel's view about self-consciousness? That self-consciousness is a NECESSARY condition of social settings: awareness of other creatures? Furthermore, Friston's point at 1:23:32 is reminiscent of Hegel's view that self-consciousness depends on intersubjective recognition!

    In Short: Cool Scientist, but over our heads
    Notes: I'm a neuroscientist, so this theoretically should be really interesting to me. I've also listened to this 1 time through before, and when re-listening I had to listen to many parts over again. I had a difficult time following Karl and Lex together, especially when the dive into the Free energy principle which is the bulk of this podcast and Karls work. More of a story would have been much better here to keep listeners engaged. Also, simplifying some of the ideas, asking dumb and straightforward questions from lex, and slowing Karl down when it comes to the significance of the free energy principle; what does it mean? What are its implications?. This would have made this podcast way easier to follow and more engaging.
    But with all this said, there were some great points here and some profound statements, especially regarding moving to change things in the world, the power of neuroimaging (and constraints), and Karls fascination with heirarchical structure (but that part too would be easy to go over your head). Would love another, longer, more nuance, and story packed episode with Karl in the Future.

    His comment on machine learning ignoring movement remind me Alan Kay saying that we put more effort for getting data than finding meaning. The parallel is maybe totally dumb, but I assume.
    Other than that, this was a crazy conversation. Really enjoyable, funny, mind blowing, "deep". Thanks for that.
