Ep 94: Wealth and the Conflict of Ideas

Ep 94: Wealth and the Conflict of Ideas

October 12, 2021

I recommend this episode be viewed in its video format here https://www.youtube.com/watch?v=TfuQI_LgDBE or here https://odysee.com/@BrettHall:c/wealth-and-the-conflict-of-ideas:1 as it's got lots of nice images and videos...some of which I constructed myself. That said, the actual "message" can be appreciated fully with audio only. 

 

Although I do not explicitly mention it, this entire episode was motivated by a Sam Harris “meme post” found here: https://www.instagram.com/p/B-sWqk5n1... The claim that appears there (which reads “The free market is not producing effective responses to our most important problems” is emblematic of an intellectual culture that now holds sway not only in the academy but broadly in public discourse and, of course, it is readily consumed by people hungry for simple solutions and perversely promoted by business people afraid of their left-leaning customers. In this episode I spend time on a very brief historic analysis of the motivation for such rejections of freedom and capitalism (which we must admit are relatively new creations when put beside ancient tribalism) and I look at some of the failures of central planning or rejection of the free market. I agree with those who say “there is no actual capitalism” there are merely degrees of socialism in existence. Where there is freedom in a socialist framework, to the degree there is freedom: wealth grows. And to the degree there are top down controls: poverty increases. I regard this as an opportunity cost to some extent. It should not be necessary to defend the fundamentals of economic systems that allow for wealth creation and problem solving. But we live in a time where, for various reasons, a neo-Marxist move is on the ascendency. On that: I also voice concerns I have about allies on the side of liberty turning on one another rather too often out of concern this or that “capitalist” is not sufficiently “capitalist”. I see this as a wonderful way for socialists to continue to gain ground in institutions at all levels of government. A partial script for this episode can be found here: https://www.bretthall.org/our-most-im... This video and ones like it take many days (sometimes weeks) of production from research and reading for the script through to filming and audio recording, searching libraries of stock videos and music, organising copyright issues and finally editing - because I work alone.

October 7, 2021

In this answer David provides some unique insight into the mystery that remains the nature of the mind. We are constrained by some of what we already know (like computational universality, among other things) and so given this, what can we say about the mind?

October 6, 2021

In this “question for David” number 8 we speak about direct observation - “empiricism” and how that was progress over what came before even if it is false. More than anything else this question serves as a “teaser” for the content of question 9: some of David’s views on the nature of mind.

Ep 91: David Deutsch‘s ”The Fabric of Reality” Chapter 3 “Problem Solving” Part 2

Ep 91: David Deutsch‘s ”The Fabric of Reality” Chapter 3 “Problem Solving” Part 2

October 1, 2021

In this podcast we cover a universal scheme for problem solving and then focus in on the special case of problem solving in science and compare this to outdated and refuted attempts to explain how knowledge was supposed to be "justified". Popper wrote that "all life is problem solving" - so I discuss that briefly and throughout we consider that if problems are indeed soluble (as they are) how it is that problems eventually get solved. It takes effort, it takes creativity, the process can be messy and there is no single method: but there are ways to be right about what's going on and ways to be wrong.

This is the audio only version of the video found here https://www.youtube.com/watch?v=VxeXbTv1dug and is one of my occasional episodes backed by some music.

 

Inspired largely by the work of David Deutsch with underlying themes of Popperian critical rationalism: this is my exploration of fallibilism. The three music tracks were composed by Ketsa https://freemusicarchive.org/music/Ketsa/ and are, in order:

1. "Mixed Up"

Ep: 89 ”Quantum Information” Chiara Marletto‘s ”The Science of Can & Can‘t” Ch 4 readings and discussion

Ep: 89 ”Quantum Information” Chiara Marletto‘s ”The Science of Can & Can‘t” Ch 4 readings and discussion

September 22, 2021

As the title suggests: this is about Quantum Information. It is “Quantum Information Theory” to be more precise. Now physics is sometimes regarded as strange by people who know little about it. And even for people who know a little more about it - well they might regard quantum physics as strange. And even those who know a little about quantum physics - they can regard quantum information theory as rather esoteric. This episode, following Chapter 4 of Chiara Marletto’s excellent book, begins from the ground up to explore how quantum systems can do more with information than classical systems (which is what all present day computers use). There is an excellent talk by David Wallace about the Mach Zehnder interferometer that I mention. It’s here: https://www.youtube.com/watch?v=GRJT9... Coupled with my own remarks about it here: https://www.youtube.com/watch?v=Cu4HH... Anyone should come away with a good understanding of what is actually going on.

Ep: 88 Critically Creative (Critical and Creative Thinking 2.0).

September 11, 2021

There is an article associated with this podcast episode here: https://www.bretthall.org/critically-creative-1.html

 

I mention this article from the University of Sydney, Australia: https://www.sydney.edu.au/students/critical-thinking.html

 

While recording this podcast, I had in mind teachers: they are my primary “target audience” so to speak. But this will, I hope be useful for anyone with a “stake” in the education system: so of course students, their parents, university lecturers, administrators - people in a position to make decisions about schools and curriculum. The topic is essentially “Critical Thinking” and what I think it is, in the Popperian tradition. As I will mention, unlike even just 15 years ago, “Critical Thinking” is now a fashionable term thrown around in schools, universities and among those charged with deciding what students are taught and how. Often “Creative Thinking” is thrown into the mix as well. All sorts of activities are devised for students to improve these “skills”: sometimes entire new subjects are created for students to take that are supposed to be about improving “critical thinking”. It’s all - from the education system’s point of view - very new. And because it’s new *there* they are, largely speaking, inventing things on the fly or designating certain techniques or rules or activities “critical and creative thinking”. It really is all the buzz in many places.

Ep 87: David Deutsch‘s ”The Fabric of Reality” Chapter 3 “Problem Solving” Part 1

Ep 87: David Deutsch‘s ”The Fabric of Reality” Chapter 3 “Problem Solving” Part 1

September 7, 2021

This is the first part of a discussion about chapter 3 of "The Fabric of Reality". It is about...problem solving with a significant focus on science and how scientific theories are generated. It contains criticism of the prevailing "justificationist" and "inductivist" notions. I see it as a good companion to (perhaps an introduction to) my episode "The Aim of Science" which I would consider a little more "heavy". This was wide ranging and a lot of fun to produce!

Ep 86: The Aim of Science

Ep 86: The Aim of Science

August 28, 2021

This is an "irregular" ToKCast which is all about a short essay by Popper titled "The Aim of Science". I read parts of the essay and comment on it and compare it to some more recent developments in the philosophy of science. Readings for this - like the paper itself - can be found here: http://www.bretthall.org/the-aim-of-s... The thing about the essay that is amazing is how certain paragraphs are as clear as anything one might say on this topic today: and yet he is breaking the ground in many ways with what he is saying. People struggled until Popper to even make a coherent case for what science was all about let alone how it managed to do it. There are only a few images in this "video" so you can easily get away with listening to the audio only version of this.

The original link for this (without the introduction I provide here) can be found at: https://www.youtube.com/watch?v=zEcHS... “Do Explain” is a podcast interview series created by Christofer Lövgren (Chris as I call him because I can’t pronounce his surname). Find “Do Explain” anywhere podcasts can be found - for example Apple here: https://www.google.com/url?sa=t&rct=j... or “Tune In” here https://www.google.com/url?sa=t&rct=j... The main website and host for Do Explain for now is here: https://doexplain.buzzsprout.com In this episode I cover all my "big hits" - consciousness, free will, Bayesianism and as the original title says "The nature of knowledge".
