The Theory of Anything

This week we talk about doomers, specifically AI doomers. Why has it become such a popular notion, especially amongst those who consider themselves the most rational kinds of people, that this kind of apocalypse, amongst others, is imminent? What assumptions are behind this pessimistic assertion?This episode was actually entirely unplanned. We started recording another episode and got off on to this tangent and thought it was a fun topic.

Here Bruce starts with Popper’s assertion that theories are 100x more valuable than concepts and compares it to Douglas Hofstadter’s ideas on creativity and consciousness. But if concepts matter so little, where do conjectures originate? Popper offers little on this point, yet Hofstadter’s view of the human mind as a system of self-referential feedback loops—able to bridge gaps that formal logic cannot—may provide a useful way to think about it.And while we’re at it, let’s poke at one of the CritRats’ sacred cows: is it actually the case that observations have no role other than helping us pick between rival theories?⁠⁠Support us on Patreon

This week we welcome back Micah Redding of the Christian Transhumanist podcast. We had a joyful conversation touching on religion, science fiction, and teleology. We look at the ways science fiction and fantasy triggers our moral intuitions regarding what kind of universe we live in with respect to meaning. Do we live in an inherently meaningful universe (teleology); a meaning neutral universe in line with existentialism, materialism, or naturalism; or an actively-malevolent Lovecraftian universe?⁠⁠Support us on Patreon

Bruce compares Donald Campbell’s evolutionary epistemology and David Deutsch’s ideas on infinite knowledge growth. What is knowledge growth? Is it a rare thing limited to only biological evolution and human ideas, as Deutsch seems to argue? (Does he argue that?) Or is it a ubiquitous process that happens all around us at all levels of nature as Campbell argues?Is knowledge created in human minds an incremental process, as Campbell might emphasize, based on blind variation and selection? Or as Deutsch might emphasize, is this a cosmically significant, open-ended process based on creativity and explanation? Can these two great thinkers ideas be reconciled or are they in contradiction to each other?⁠Support us on Patreon

In our previous episode covering Strevens' critique of Popper, we briefly touched on why Bruce believes it it a mistake for CritRats to say they don't believe in beliefs. This time Bruce takes a deep dive into beliefs -- and walks back his previous statement a bit. Do humans need beliefs? Are beliefs dangerous? What is the critical rationalist position on beliefs? What did Popper say? And can we even realistically live without beliefs?And along the way, Bruce criticizes "the disobedience criteria" as a way to make his point about the value -- and dangers -- of mythic belief systems and why we need them and why they can confuse us rationally. ⁠Support us on Patreon

This week we interview Logan Chipkin. Logan is a writer and author of several books. Recently he co-authored and published The Sovereign Child about raising children without coercion, and The Lords of the Cosmos, which tells the story of progress through the lens of good philosophy. Logan is also the president of Conjecture Institute, which is a brand new organization dedicated to promoting the worldview of Karl Popper and David Deutsch. (Follow on X)Here we discuss the New Right vs libertarianism. We consider: What is the core difference between liberalism, conservatism, and libertarianism? Why are so many libertarians into conspiracy theories? How are we to think about Popperian arguments against utopianism applied to libertarians? Does it make sense for an anarcho-capitalist to be hawkish on military intervention in places like Ukraine? And why have mainstream conservatives strayed so far from making intellectual arguments for their positions as they may have in the days or Milton Friedman?What criticisms can be correctly leveled against the Right today, especially economically but also in terms of their methods. And what does the New Right 'get right' according to Logan?Right wing resources suggested by Logan:The DispatchCommentary Magazine PodcastNational Review PodcastThe Politically Incorrect Guide to American HistoryThe Right: The Hundred-Year War for American ConservatismRadicals for Capitalism: A Freewheeling History of the Modern American Libertarian Movement⁠Support us on Patreon

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.

This week we consider: Is falsification falsifiable? Was Popper a “naive falsificationist”? Why do so many people think he was? (Including at least one of his own students!)Is falsification itself a philosophical theory that makes it immune from falsification? Does the Duhem-Quine problem, or the assertion that theory exist in an interwoven web of other theories, create a problem for falsification? What exactly is falsification anyhow? It's about showing that a theory is false, right? Right? Popper?Bruce considers these questions and more as our infinite journey into epistemology continues.
