0:00 One of the leading theories of consciousness, Integrated Information Theory, says it comes from the back of your brain.0:08 Another, Global Neuronal Workspace Theory, puts it squarely in the front.0:13 And they're both considered the most promising scientific explanations we have.0:19 Exactly.0:19 Last week on Clash of Minds we talked about unsolved mysteries, but this one feels like the biggest of all.0:27 We can’t even agree on WHERE in the head it is, let alone what it IS.0:32 And that's the whole debate, isn't it?0:35 The mainstream scientific view, your view I suspect, is materialism.0:40 Consciousness is an emergent property.0:42 It’s a byproduct of, uh, enough neurons firing in a complex enough way.0:47 Matter is fundamental, and consciousness just sort of… pops out.0:52 I wouldn't say "pops out." I'd say it arises from a high degree of organization.0:58 Just like wetness arises from water molecules, consciousness arises from neural computation.1:04 There’s ZERO evidence for anything else.1:07 We can literally see brain activity corresponding to thoughts.1:12 Oh, you can see correlation.1:14 Of course you can.1:15 If I smash a TV with a hammer, the TV show goes away.1:19 That doesn't mean the TV was generating the show.1:22 It was a receiver.1:24 Okay, but that's an old analogy.1:26 We have way more than that.1:28 We can stimulate parts of the brain and produce conscious experiences.1:33 That’s not a receiver, that's a generator.1:36 You can produce flashes of light and muscle twitches.1:40 You can't produce the subjective experience of seeing the color red, or the feeling of awe.1:46 That's the hard problem of consciousness, and materialism has absolutely no answer for it.1:53 None.1:53 I'll give you that the hard problem is...1:56 hard.1:56 Explaining qualia—the private, subjective feeling of things—is the wall we keep hitting.2:03 But saying it's fundamental to the universe feels like giving up.2:07 Does it?2:08 Or does it feel like opening up the inquiry?2:11 Thinkers like David Bohm proposed that consciousness isn't a fluke of biology but a basic feature of reality.2:19 The brain doesn't create it; it tunes into it.2:22 It acts as a filter or an amplifier.2:25 But that’s unfalsifiable!2:26 How do you test for a "universal consciousness field"?2:30 It sounds more like philosophy or spirituality than science.2:35 At least with IIT and GNWT, we have concrete, testable hypotheses about brain structures.2:41 And those hypotheses are failing to explain the one thing they're supposed to explain!2:47 Calling consciousness "emergent" is just a fancy way of saying "and then a miracle happens." It's a placeholder word for ignorance.2:56 The Fractal Consciousness Theory, for example, suggests it's a fundamental pattern that repeats at different scales.3:05 That’s a far more elegant solution.3:07 Elegant, maybe.3:08 But is it true?3:09 The materialist view, for all its gaps, is grounded in what we can observe and measure.3:16 Your view requires us to believe in a property of the universe that is, by its nature, invisible.3:23 Soooo, like dark matter?3:24 Or dark energy?3:25 Science is full of things we infer from their effects before we can see them directly.3:32 The biggest effect to explain here is your own subjective experience.3:36 Materialism just pretends it's not a big deal.3:40 I think it's the ONLY deal.3:42 Okay...3:42 I hear you.3:43 The dismissal of subjective experience is a weak point for my side.3:48 It's treated more as an annoyance than the central data point.3:52 And the lack of a clear mechanism is the weak point for mine.3:57 I’ll grant you that.3:58 "Tuning in" is a metaphor, not a mechanism.4:01 For now.4:02 So we have one side with a mechanism that can't explain the experience, and another side that prioritizes the experience but doesn't have a mechanism.4:12 That's a pretty fair summary.4:14 We're stuck between a theory that explains everything except consciousness, and a theory that explains consciousness but not much else.4:24 It feels like the real question isn't just about brains versus the universe.4:30 No, it's not.4:31 The real question is whether reality is fundamentally dead, or fundamentally aware.4:36 Is the universe just a bunch of rocks and gas that accidentally woke up on one tiny planet?4:43 Or is awareness baked in from the very beginning?
