This is a question for David about Popper's notion of "verisimilitude". Can we utter the truth? What does David think about probability? Two excellent talks by David referred to in this video are the one he did on "Statements, Propositions and Truth" with the Oxford Karl Popper Society https://www.youtube.com/watch?v=DZ-opI-jghs and the one on Probability (which is somewhat misleadingly titled "Da...

Yes, this is me asking David Deutsch about the supposed "evidence" of UFOs that are the US Military's release of footage from jet aircraft that have become known as "Tic Tacs". I do not mention this in the video, but the best explanation I have seen of at least some of this stuff is by Mick West who was able to reproduce at least some of the images: https://www.youtube.com/watch?v=Le7Fq... Neil de...

This is the second part of my interview with David - with me making some remarks about it. I will eventually release the entire conversation.   If you would like to support this endeavor, do consider making a one off (or even monthly) donation by clicking the “Donate” button on the front page of www.bretthall.org or you may “subscribe” at https://patreon.com/BrettRHall or contribute "per episode"...

The first episode in a new series of "Questions for David" - featuring David Deutsch himself - as a supplement or appendix to my series on "The Beginning of Infinity". This first one is about "The Reality of Abstractions".

This is the final "The Beginning of Infinity" episode. I must say: the Youtube version of this contains many useful videos and images to help with what is being described and explained.    Either way: Enjoy! (And rest assured "The Science of Can and Can't" and "The Fabric of Reality" episodes will continue to come out weekly. This is not the end, but "The Beginning").   Here is a time-stamped summ...

This podcast is abut crypto - and recent volatility. I explain some of the psychological motivation for crypto currency and compare it to fiat currency and the liabilities of both. Some comments on so-called “Modern Monetary Policy/Theory”.    If you wish to support my podcast, that can be done here: ToKCast is creating Videos, Podcast and Articles | Patreonhttps://www.patreon.com › BrettRHall  or...

In this, the second part of discussion about the first chapter of “The Fabric of Reality”, we delve more deeply into what the distinction between “The theory of everything” that particle physicists have in mind and what David Deutsch’s more encompassing, more grand vision is for a unification of our deepest theories (of which the particle-physicists hoped-for unification of the forces is only a pa...

This episode is focussed on the physics content of chapter 1. I explain what the current “conception” of physics is in terms of dynamical laws and initial conditions. I run through a simple example of how equations of motion are used and discuss how this has been, hitherto, the way physics has been done, is done and is expected to continue to be done according to most philosophers and physicists....

The title says it all. This episode is about quasars. I return to my original “training” in astrophysics in order to correct some misconceptions that may have crept into my video titled “The Nexus” here: https://www.youtube.com/watch?v=zpTxBkmr4LE   This episode covers three basic things: The history of the discovery of quasars The physics of quasars Varieties of quasars As with episodes of this k...

The Penultimate “The Beginning of Infinity” episode. Herein we contrast pessimism with optimism - what the conditions are for providing succour to either philosophy and who some of the leaders are. While science writers such as John Horgan, author of “The End of Science” may provide something of an introduction to the ways in which people can conclude “the end is night”, philosophers like Nick Bos...

This is an exploration of the first 7 pages of "The Fabric of Reality". I spend much of the time talking about the significance of the book, how I missed so much even on my first few readings of it and how we find even in these first few pages not merely the seeds of aspects of David Deutsch's later work, but an entire forest of important ideas that motivate much in "The Beginning of Infinity" and...

This is the first episode in a new series devoted to an entirely new book: “The Science of Can and Can’t” by Chiara Marletto. Get the book anywhere ebooks are available (as of May, 2021) and learn more about Chiara and her work here: https://www.chiaramarletto.com ​ This book is an amazing work. It presents for the lay reader an introduction to “Constructor Theory” without losing any scientific or...

In this second part I spend a large portion of our time comparing author John Horgan's work "The End of Science" to David Deutsch's "The Beginning of Infinity". What errors does Horgan make on the way to reaching the conclusion that science is coming to an end? I also summarise cases where critics of Popper seem to turn to character assassination rather than being focussed on his ideas. We end by...

This episode is identical to episode 59 - only it contains no music. I don't think this is as good :) My preferred way to experience this is the video version version which is here: https://www.youtube.com/watch?v=zpTxBkmr4LE  .  of this video (there is another published alongside this without any music -again, I don't think it is as good, but if you prefer "no music" - there is a video version wi...

My preferred way to experience this is the video version version which is here: https://www.youtube.com/watch?v=zpTxBkmr4LE  .  There is another version also published alongside this without any music - I don't think it is as good, but if you prefer "no music" - there is a version without that here: https://youtu.be/Ky4vMllidvM ​   Note that episode 60 of the podcast is just "Episode 59 without th...

The beginning of "The Beginning" which is the chapter at the very end of "The Beginning of Infinity". :) Ignore what I say early on in this episode: this is episode 58, not 57. In this episode we revisit the idea that science, or knowledge broadly is coming to an "end". Even Feynman could become uncharacteristically pessimistic in this regard. Every new discovery reveals that there is more to know...

This is a podcast all about "Existential Risk". Made at the request of a Patreon, I cover the usual spectrum of ways in which people guess civilisation might end, discuss how to think about this from a rational - but critical - perspective and how to remain optimistic in the face of public intellectuals bombarding us with these claims about the coming end-times. If you would like to get early acce...

The final part of the penultimate chapter. Here we cover "The parable of Europium" and other memorable pessimists from David's formative years. Some analysis of the present concerns about climate change and the rational problem solving - and optimistic approach as contrasted to the standard pessimistic lines.

What does it mean for something to exist?

Marx, Engels and Diamond present to us a vision of people as being in some sense impotent in the grand historical scheme - subject merely to natural forces and thus able to be predicted by a kind of natural law. This reductive view of people and their place in history (and the cosmos) leads to terrible historical ideas that bleed into pessimistic political ideologies. The truth instead is not blea...

This is additional material about Chapter 6 of "The Beginning of Infinity" - but goes into some additional areas. I compare Greek Gods to Blockchain (in a sense). I think "The Jump to Universality" is a particularly poorly understood chapter. I hope this inspires many to go back and re-read that part of the book. Again. And again.

Easter Island, Incans, Llamas and Australia. Resources and knowledge, creativity and stasis. We begin to bring together the chapters that have come before as we move into the crescendo of "The Beginning of Infinity". Images (on Youtube) all used under a creative commons licence. All music composed by me.

What does the watchword of today "sustainable" really mean when taken seriously? In this episode we compare two titans of science communication: David Attenborough and Jacob Bronowski - for although they have inspired generations of scientists and those interested in science, their underlying philosophies could not have been more different. What are those philosophies and what consequences could t...

The 50th episode! This is the third part (given there was a part 0, introduction) referring to chapter 16 of "The Beginning of Infinity" with substantive readings. We get into how memes evolved in non-human animals and then how these memes, and genes at some point allowed for a jump to universality. Specifically the universality of explanatory knowledge - which is a quality of a special kind of so...

What it says in the title :) A short and sweet introduction to a particular way of thinking and knowing. This is all about fallibilism and the possibilities that being wrong opens up.
