This is a podcast primarily about the work of philosopher and physicist David Deutsch and related matters (such as Popperian epistemology). I read from and comment upon the books ”The Beginning of Infinity” & ”The Fabric of Reality” (both by Deutsch), ”The Science of Can & Can’t” (by Deutsch’s collegue Marletto) and ”Rationality” by Pinker (so far). In addition I make stand alone episodes about topics like resources, environmentalism, economics, science, philosophy, epistemology (especially explanations) and reason broadly.

Ep 38 Ch 15 "The Evolution of Culture" Part 1 14.11.2020

This is the first in a 3 part series devoted to Chapter 15 of "The Beginning of Infinity" by David Deutsch. All about "The Evolution of Culture", in this part we are looking at the notion of a meme and consider under what conditions ideas replicate. As we touch upon: this is a question of civilizational consequence as it is related to the ability of a society to break out of being "static" (one wi...

Ep 37: An intermittent introduction to Popper and Deutsch 13.11.2020

A very brief, and personal, introduction to the philosophy of Karl Popper and David Deutsch. Note that the Youtube version of this exists in 3 parts, each of which has visuals that may help some with the explanations.

Ep 36: The Borders of Ideas 21.10.2020

This is some commentary upon a recent debate Douglas Murray was engaged in - which can be found here: https://www.youtube.com/watch?v=i3sSnmq9uKU It is, broadly speaking, an excellent encounter, modulo - as Douglas rightly observes - the tendency for his interlocutor to resort to insults or other ad hominem remarks. I reflect on Douglas' position (with which I largely agree) and attempt to connect...

Ep 35 Ch 14 "Why are Flowers Beautiful?" 20.10.2020

Audio listeners, please note: This episode contains a lot more visuals than my usual podcasts. As always this can be found on Youtube at https://www.youtube.com/watch?v=gWZ4GcRd-_8  if you want the full experience. I'm referring to images and so on throughout, or the images are illustrating what I am saying without comment. In this chapter we counter a number of prevailing views about the arts: th...

Ep 34 Ch 13 “Choices” Part 2. Some readings and remarks. 18.10.2020

This is some reading and reflections upon chapter 13 of "The Beginning of Infinity". In this second part we consider criteria for democracy and democratic institutions. I take a deep dive into Popper's own writings on the topic to supplement the material in David's book. There is even, what we might call, some "self help" when it comes to making choices, or making better choices, or cultivating a...

Ep 33 Ch 13 "Choices" Part 1. Some readings and remarks. 09.10.2020

This is the first episode of 2 parts all about chapter 13 "Choices" from "The Beginning of Infinity" by David Deutsch. Here we take a deep dive into voting systems and what this means for decision making more broadly: both as societies and individuals. Logic and fairness seem to come in conflict if we become reductionist and turn only to mathematics in order to make rational choices. As always the...

Ep 32 Ch 12 "A Physicist's History of Bad Philosophy" Part 3. Some readings and remarks 30.09.2020

This is the third episode in a 3 part series about chapter 12 of "The Beginning of Infinity". This part is focussed in a more specific way on bad science (that being explanationless science). We also delve into the nature of personhood once more, its moral significance and the possibility of having an experience as a human animal versus a non-human animal. 

Ep: 31 Ch 12 "A Physicist's History of Bad Philosophy" Part 2: Some readings and remarks. 06.08.2020

This is the second episode in a 3 part series about chapter 12 of "The Beginning of Infinity". Here we get into some of the connections between poor "interpretations" of quantum theory and relativism.

Ep: 30 Ch 12 "A Physicist's History of Bad Philosophy" Part 1: The Introduction 06.08.2020

This is the first episode in a 3 part series about Chapter 12 of "The Beginning of Infinity". As this chapter is about Bad Philosophy, I thought an episode that sets the context - especially the contemporary context - might be timely. 

Ep: 29 Ch 11 "The Multiverse" Part 5 02.07.2020

The final part of "The Multiverse" series - and with some discussion (and a story!) of some little known material about how to test "The Multiverse" against other (so-called) interpretations of quantum theory.

Ep 28: Ch 11 "The Multiverse" Part 4 15.05.2020

With apologies to audio only listeners, this one was up on Youtube for a while (and contains a few visuals) - I simply forgot to upload it to Podbean and Apple Podcasts. It is largely an analysis of common misconceptions about the multiverse and references a conversation between Sam Harris and Bret Weinstein who spoke about the multiverse during a recent conversation. 

Ep 27: Christian Atheists 25.04.2020

This is a very brief and non-standard non-Beginning of Infinity podcast. It also does not mention COVID-19 at all. It is inspired in part by some remarks made by Yaron Brook. There is an important post associated with this episode which appears here: http://www.bretthall.org/blog/mainstream-morality As with my last episode, we will return to the usual programming soon.

Ep 26: Problems, Knowledge and Wealth 17.04.2020

This is a non-Beginning of Infinity Podcast. While it makes some references, as always, to the work of David Deutsch, it is primarily some thoughts about finding ourselves in a given problem situation and what we need to find our way out in time. Of course there is some reference made to the present COVID-19 situation. A rather different episode to the usual. I hope to get back to regular programm...

Ep 25: Ch 11 "The Multiverse" Part 3 03.03.2020

Some readings and remarks about David Deutsch's "The Beginning of Infinity" Chapter 11 "The Multiverse". This is the 3rd episode in this series. As with some of the others, audio only listeners may miss a few visuals in this one...but they're not absolutely crucial this time around. There is a way to support this endeavor on my website www.bretthall.org  where you can click the donate button and c...

Ep 24: The Multiverse, Part 2 25.02.2020

This is the first episode that includes reading from Chapter 11 of "The Beginning of Infinity" about "The Multiverse". It is less edited...and rather more conversational. Compare this to episode 23 and let me know what you prefer. I will take on board comments moving forward. Thank you. As always, donations are welcome at www.brethall.org  on the "donate" button. 

Ep 23: The Multiverse, Part 1 19.02.2020

This episode is an introduction to chapter 11 from "The Beginning of Infinity". While there are no readings from the book this time around, there are readings from "The Fabric of Reality". Audio only listeners should be aware that there is a significant visual component of this episode: animations, diagrams and so forth.

Ep 22: The Logic of Experimental Tests 11.02.2020

This is not a regular ToKCast (about a chapter from "The Beginning of Infinity"). Instead it will serve in part firstly as a stand alone episode about an esoteric piece of epistemology: what is the function of the experiment in the natural sciences? (As explained by David Deutsch in his paper "The Logic of Experimental Tests particularly Everettian Quantum Theory"). I make many remarks - including...

Ep 21: Ch 10, Part 2 "A Dream of Socrates" 01.02.2020

In this, the second episode covering Chapter 10 "A Dream of Socrates", we encounter Plato in dialogue with Socrates. An attempt is made to learn epistemology from Socrates by Plato. Epistemology is applied to political institutions and the concept of dynamic and static societies is explored and we get our first sense of what anti-rational memes are about (though this terminology is not yet being u...

Ep 20: Ch 10, Part 1 "A Dream of Socrates" 26.12.2019

In this, the first episode covering Chapter 10 "A Dream of Socrates", we explore epistemology directly. Hermes comes to Socrates in a dream (or somehow!) and uses a quite "Socratic Method" to draw out Popperian epistemology from Socrates. Empiricism is refuted and the correct way knowledge is guest and criticized to improve it discussed.

Ep 19: Mr. Popper's Problems 17.12.2019

An irregular episode barely touching upon "The Beginning of Infinity". Somewhat self-indulgently, and purely for my own fun, I take a lesser-known Popper paper - found here  http://www.bretthall.org/the-nature-of-philosophical-problems.html  and provide lengthy commentary upon it with some remarks about its significance for some contemporary issues.

Ep 18: Ch 9, Part 3: “Optimism” 31.10.2019

In this, the final episode covering Chapter 9 Optimism, we explore optimism as applied to politics and institutions. A pessimistic view of people, as animals that sometimes cannot be reasoned with, would imply the initiation of force is required. But understanding people as beings of compassion and reason means we should initiate kindness and use force only ever in response to violence. Pessimism...

Ep 17: Ch 9, Part 2: "Optimism" 19.07.2019

In part 2 on Optimism, we explore the implications of David Deutsch's philosophy for individuals and institutiuons. Given people are the agents that create knowledge - the solutions to problems - what moral stance should we take with respect to them? How will this affect our future and what threats to optimism still exist in the contemporary zeitgeist?

Ep 16: Ch 9, Part 1: "Optimism" 19.07.2019

This is the first of a 3 part series on chapter 9 of David Deutsch's "The Beginning of Infinity". Chapter 9 is titled "Optimism" and the week this is published marks the 50th anniversary of the first steps taken by humans on the moon. If we choose to continue to pursue solutions in an open ended way - if we choose to embrace what might be called "Deutschian Optimism" then next it can be Mars...and...

Ep 15: A diversion on Free Will and Artificial Intelligence 22.04.2019

Note that this one is not primarily about a chapter from "The Beginning of Infinity". Some remarks on Sam Harris position on "Free Will" as articulated in his book of the same name. I do mention BoI and FoR of course and borrow heavily from David's work in constructing the arguments herein. Most especially the "Copper Atom at the tip of the nose of the statue of Winston Churchill in Parliament Squ...
