Summary

I personally subscribe to The Economist. TOE listeners get 35% off the annual subscription. No other podcast has this! https://economist.com/TOE Joscha Bach explores the nature of intelligence, consciousness, and reality, tackling questions from the definition of truth to the existence of free will. He contrasts various theories of consciousness, discusses the role of art and society, and presents his own model of control, attention, and reflective recall.0:00 Introduction0:17 Work ethic and daily routine1:35 Definition of truth4:41 Quantum graph as nature's substratum6:25 Mathematics as language descriptor13:52 Constructivist mathematics and reality17:06 Meaning of existence and pi20:14 Something vs nothing, existence default21:11 Bach's model vs multiverse26:51 Is the universe deterministic28:23 Determining initial conditions and rules30:55 Nature of time, fundamental?34:21 Optimal algorithm for finding truth40:40 Simplicity of fundamental laws50:17 Art and the artist's cost function54:02 Ideas as stories driven by intuitions58:00 Society's minimal role in training intuitions59:24 Art under repressive government1:04:01 Market case for civil rights1:06:40 Fascism vs communism1:10:50 Control/attention/reflective recall model1:13:32 Consciousness vs attention1:16:02 Chinese Room experiment1:25:22 Understanding predicated on consciousness1:26:22 Integrated Information Theory (IIT)1:30:15 Donald Hoffman's consciousness theory1:32:40 Hofstadter's strange loop theory1:34:10 Holonomic brain theory1:34:42 Dennett's consciousness theory1:36:57 Sensorimotor (embodied cognition) theory1:44:39 What is intelligence?1:45:08 Intelligence vs consciousness1:46:36 Free will in Bach's model1:48:46 Opposite of free will and addiction1:51:48 Changing identity to live forever1:59:13 Depersonalization and illusory self2:02:25 Fear of loss of control2:05:00 Heart and conscience2:07:28 Testing/falsifying Bach's consciousness model2:13:46 Evolution of Bach's model2:14:41 Stopping lucid dreaming2:15:33 Dreams and GANs2:18:08 Why we don't remember dreams2:19:58 Are dreams real?

Okay, I think it's a good day for 2020. The sun is out again. This sky doesn't look like Mars, as far as I can see. Air is so-so, but meteor

0:43.3

didn't hit yet, and we're still waiting for the big one in the Bay Area. What's your work ethic like?

0:48.6

What do you do on a usual day? There are no usual days. So in some sense, every day is its own and every day has

0:58.0

its own demands and so on. And I do block out times and do plan things ahead. But for the

1:06.8

part, I get up. I have breakfast. I work, I spend time with the family in between,

1:12.7

and at some point I maybe reads a few pages in a book or watch a movie with the family and go to bed.

1:22.6

Do you tend to work in solid blocks uninterrupted because you need that for focus?

1:30.5

It depends on the type of work so when i uh write code i need long solitary times alone if i want to write a book i need to have solid

1:38.7

weeks uh weeks for myself so i don't write a book at this point um maybe i figure out how to do this anyway while being locked up with the family.

1:47.0

And when I do conceptual work and so on, I can do this in short intervals and sometimes I do something else,

1:54.0

interrupt it because I realize I need to write something down.

1:58.0

We're going to get into some fairly deep questions right off the bat. So what is your

2:03.2

definition of truth? Do you take a correspondence theory of truth, for example? I think that

2:12.4

truth is defined in a mathematical paradigm, which means it's defined within a language.

2:20.3

And it's a certain value that you set on variables that have the property that they can be

2:29.3

a two or false or have a truth value that varies in degrees.

2:35.0

And in some sense, truth is a predicate that you can calculate in this context.

2:41.0

And you can translate this into the languages that our mind is typically using, which are models.

2:48.0

And in these models, we can have some kind of truth definition, which means that the model, depending on the type of model that you have, can conform to any of your mathematical truth definition. So it can be something that is, can be reduced to a set of axioms, for instance. And this means that it can be in some sense compressed to the set of axioms

3:10.3

or expanded from the set of axioms into a certain state of that descriptive system.
