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.","last_synced_at":"2026-07-05T14:17:01.933436+00:00","page_url":"https://stenobird.com/podcast/tokcast-76992"},"episode":{"title":"Ep 263: David Deutsch's \"The Fabric of Reality\" Chapter 13 \"The Four Strands\" Part 4 - and final.","slug":"ep-263-david-deutsch-s-the-fabric-of-reality-chapter-13-the-four-strands-part-4-and-final","published_at":"2026-07-04T14:17:48+00:00","page_url":"https://stenobird.com/podcast/tokcast-76992/ep-263-david-deutsch-s-the-fabric-of-reality-chapter-13-the-four-strands-part-4-and-final","show_page_url":"https://stenobird.com/podcast/tokcast-76992","url":"https://brettroberthall.podbean.com/e/ep-263-david-deutschs-the-fabric-of-reality-chapter-13-the-four-strands-part-4-and-final/","audio_url":"https://mcdn.podbean.com/mf/web/vcznnzfhw88f9p5v/Final_Four_podcast77nt0.mp3","summary":"How do the Four Strands of the Fabric of Reality - Quantum Physics, Computation, Epistemology and Evolution by Natural Selection hold together? What does taking them each seriously and all of them together seriously? Is it possible to construct a worldview without one of them or based on a single one alone?
