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 23: The Multiverse, Part 1 19.02.2020 1:02:24
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 1:15:16
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 56:33
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 52:36
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 1:08:39
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 47:04
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 36:40
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 1:09:07
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 34:34
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...
Ep 13: Ch 8 "A Window on Infinity" Part 1 22.04.2019 20:52
Unlucky 13: The microphone failed for this one, so the backup audio has been used. It's a little sub par but still "listenable". The next one sounds better. Note to audio-only people: some visuals are in this one - so you can find that on Youtube.
