The Theory of Anything
Bruce Nielson and Peter Johansen
A podcast that explores the unseen and surprising connections between nearly everything, with special emphasis on intelligence and the search for Artificial General Intelligence (AGI) through the lens of Karl Popper's Theory of Knowledge.
David Deutsch argued that Quantum Mechanics, Darwinian Evolution, Karl Popper's Theory of Knowledge, and Computational Theory (aka "The Four Strands") represent an early 'theory of everything' be it science, philosophy, computation, religion, politics, or art. So we explore everything.

Episode 117: Jonathan Rauch
This week we had the absolute honor of interviewing Jonathan Rauch. Rauch is an extremely influential public intellectual (journalist and author) who is also a Popperian. His 1993 book, Kindly Inquisitors, makes the epistemic case for free speech. It is a stone cold classic that will be with us for a long time. In his 2021 sequel, The Constitution of Knowledge, he considers how society collectively produces knowledge and the dangers of misinformation. He has also written a book that provided the “intellectual framework” for the case for same sex marriage. (link)And though he says he's a Jewish atheist, his latest book, Cross Purposes, is a critical, yet reverential, book on Christianity making the case that our society needs more and not less Christianity.
