This episode is an introduction to the chapter. Although there are some readings, they are limited and I provide context by diving deep into David's more recent work on all this. Specifically we go through the connection of Chapter 10 here (published in 1997) and Chapter 5 "The Reality of Abstractions" from "The Beginning of Infinity" (published in 2011) and then also in light of David's recent speech given at his Dirac Medal award ceremony (published in 2017) - here is the timestamped link to that https://www.youtube.com/live/J7HeDX_7... and the text of that speech is online here: https://www.daviddeutsch.org.uk/wp-co... None of that is essential reading (or listening) for this episode - but it can help. As always - buy "The Fabric of Reality" and read along as I never read the entire chapter - just excerpts!
