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.
