E264 - Ep 263: David Deutsch's "The Fabric of Reality" Chapter 13 "The Four Strands" Part 4 - and final.

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? What do they imply about free will and consciousness? Doesn't making progress require us to assume them false? All this and more.
