ToKCast
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 48: Cosmological Economics 13.01.2021 31:44
This episode is highly visual and better viewed on Youtube here: https://www.youtube.com/watch?v=VlcQ4ZFKrKk However, the substance is still there in this purely audio-only version. This is another episode not primarily about "The Beginning of Infinity" but it is deeply inspired by it. It is a discussion exploring the "resources" debate. Are resources finite or infinite? I look at the intersectio...
Ep 47: Are we alone? 07.01.2021 1:06:01
A ToKCast Special: Brett talks about what he's learned over the years from various academics about the question of alien life. Although I don't mention it, I draw my inspiration from an academic paper I wrote years ago as part of my Masters degree in Astronomy - it can be found here: The Rare Earth That might be a bit more sober, hard-going and not exactly entertaining. I hope this video is fun. I...
Ep 46 "The Evolution of Creativity" Part 1 07.01.2021 40:16
This is the second part (after a part 0, introduction) referring to chapter 16 of The Beginning of Infinity with more substantive readings. We get into imitation and compare how apes "ape" and parrots "parrot" to what humans are doing when they learn. Meme replication and lyrebirds make an appearance.
Ep 45 Free Will Exists 25.12.2020 26:31
This is not a regular episode - and if you have listened to episode 44 you do NOT need to listen to this because it is simply excerpts from that episode. It is simply an extraction from that episode of the material - solely my remarks rather than any reading - about the concept of "free will". The following is the Youtube description of this episode: This is an excerpt from https://www.youtube.com...
Ep 44 Ch 16 "The Evolution of Creativity" Part 0 25.12.2020 1:11:56
Early on in the episode, I wrongly refer to this as "Episode 43". It's not: it's episode 44. This particular episode is largely about the concepts underpinning chapter 16 - with very little reading (I get through the first page or so). We explore creativity, choice and the associated "mysteries" (or problems of) consciousness and free will. Are these all facets of the same underlying - deeper trut...
Ep 43 Ch 15 "The Evolution of Culture" Part 3 24.12.2020 1:16:38
This is the third 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 conditions under which a dynamic society can gradually evolve and persist. Importantly we distinguish between rational and anti-rational (not merely irrational) memes.
Ep: 42 An autobiography of wealth 10.12.2020 34:21
This episode is not about "The Beginning of Infinity". It is largely a reading of an article that can be found on my website at http://www.bretthall.org/blog/an-autobiography-of-wealth The purpose of that article and this episode is to discuss the pervasive claim that the middle classes have seen a stagnation in "real wage growth". I do not go deep into economic matters but rather take a personal...
Ep 41: Deutsch Discoveries: Part 2 of an introduction to the philosophy of David Deutsch 04.12.2020 13:22
In this episode I cover more of David Deutsch's contributions to philosophy. In order these are: 1. The true function of evidence in science 2. How the quantum multiverse is a testable theory 3. All evils are due to insufficient knowledge and how morality is about "What to do next". 4. The mathematician's misconception (i.e: that mathematical proof is independent of the known laws of physics).
Ep 40: Popper Pieces - Part 2 of an Introduction to Popper 20.11.2020 12:05
This is part 2 of my introduction to Popper series. Here I cover 1. The concept of "conjectures" 2. Common Sense 3. Realism 4. The bucket and the searchlight 5. Debating definitions Yes. It's only 2 episodes in, and I have violated my self-imposed 10 minute limit rule. But I think it was worth it, rather than splitting these in two.

Ep 39 Ch 15 "The Evolution of Culture" Part 2 19.11.2020 52:18
This is the second 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 causes of a static society: that rule (rather than the exception) about progress coming to a halt in human communities. We follow on from part 1 in looking at how memes get replicated and how different kinds of memes h...
Ep 38 Ch 15 "The Evolution of Culture" Part 1 14.11.2020 53:51
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 16:35
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 32:10
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 1:15:49
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 47:52
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 1:20:03
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 1:13:03
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 57:25
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 1:15:57
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 1:19:40
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 1:38:42
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 9:06
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 1:08:22
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 1:00:37
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 40:12
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.
