This is a question for David about Popper's notion of "verisimilitude". Can we utter the truth? What does David think about probability? Two excellent talks by David referred to in this video are the one he did on "Statements, Propositions and Truth" with the Oxford Karl Popper Society https://www.youtube.com/watch?v=DZ-opI-jghs and the one on Probability (which is somewhat misleadingly titled "David Deutsch on Physics Without Probability" - it's actually far broader than this and should be required viewing for anyone who thinks they already understand lots about probability. After this, they might need to rethink their life ;) https://www.youtube.com/watch?v=wfzSE...

Yes, this is me asking David Deutsch about the supposed "evidence" of UFOs that are the US Military's release of footage from jet aircraft that have become known as "Tic Tacs". I do not mention this in the video, but the best explanation I have seen of at least some of this stuff is by Mick West who was able to reproduce at least some of the images: https://www.youtube.com/watch?v=Le7Fq... Neil deGrasse Tyson also makes broadly similar remarks to David in this podcast with Sam Harris: https://www.youtube.com/watch?v=VBVg5... Whatever the case, the deeper point is the more general one. When we do not know the explanation for a set of observations, then we have a problem. Not a solution. In this case, we seem to have either very prosaic solutions (as Mick West explains - in the form of camera effects) or perhaps something we "don't know". What we do not have is "evidence for" something amazing. Namely alien life visiting us in their spacecraft. The only way "evidence for" actually works is when it *rules out* every other theory. That is, in fact, the purpose of evidence in science. For more on that, see here: http://www.bretthall.org/general-rela... and here: http://www.bretthall.org/philosophy-o... #Tictacs #UFO

This is the second part of my interview with David - with me making some remarks about it.

The first episode in a new series of "Questions for David" - featuring David Deutsch himself - as a supplement or appendix to my series on "The Beginning of Infinity". This first one is about "The Reality of Abstractions".

This is the final "The Beginning of Infinity" episode. I must say: the Youtube version of this contains many useful videos and images to help with what is being described and explained.    Either way: Enjoy! (And rest assured "The Science of Can and Can't" and "The Fabric of Reality" episodes will continue to come out weekly. This is not the end, but "The Beginning").   Here is a time-stamped summary of the contents of this episode: 00:00 “The Horizon”: An introduction to “The Beginning of Infinity” 03:10 The Beginning. A throwback. 04:20 The point of all this. 06:15 Comments on Ricky Gervais and Sam Harris “Absolutely Mental” podcast and related themes 09:30 A place for religion and people. 16:00 A central message of BoI 16:45 Books that inform a worldview: including "The Fabric of Reality" by David Deutsch and "The End of Faith" by Sam Harris 22:30 Some criteria for understanding 27:40 Competing “epistemologies”. 31:20 Some comments on Ayn Rand’s philosophy 32:30 The “knowledge density” of "The Beginning of Infinity" 38:20 Critical thinking 43:15 Common Sense Realism 47:30 The end of the introduction 48:00 Reading Part 1 49:05 My reflections on historian Roy Porter and the competing Enlightenments 56:45 Reading Part 2 57:00 Prophesies and Predictions. 59:15 Reading Part 3 59:30 "Popperian Provisos" 1:00:35 Reading Part 4 1:00:51 The infinite potential of explanatory knowledge 1:01:40 Reading Part 5 1:04:10 Physical reality and laws of physics 1:05:15 Reading Part 6 1:05:30 Simulations vs recordings of people 1:06:35 Reading Part 7 1:08:00 Misunderstandings of Explanatory Universality 1:10:00 The Final Reading 1:11:00 The Beginning.

This podcast is abut crypto - and recent volatility. I explain some of the psychological motivation for crypto currency and compare it to fiat currency and the liabilities of both.

Discover the fascinating distinction between a simple theory of everything in physics and David Deutsch's grander vision for unifying our deepest theories. Explore the mind-bending concept of emergence and how it challenges traditional views. Unravel the mysteries of quasars and their role in reshaping our understanding of the universe. Dive into the balance between specialization and generalization in knowledge, all while pondering the intricate connections between different fields of study. Humor and philosophy meet in the Parable of the Copper Atom!

This episode is focussed on the physics content of chapter 1. I explain what the current “conception” of physics is in terms of dynamical laws and initial conditions. I run through a simple example of how equations of motion are used and discuss how this has been, hitherto, the way physics has been done, is done and is expected to continue to be done according to most philosophers and physicists. We then compare this vision of physics to what constructor theory aims to achieve by considering more than just a single thread through the fabric of reality (what was, is and will be) and instead to consider what might have been and might still be. This clearly has implications for knowledge and, again, we hint at the possibility of a physics of epistemology. It also opens up the possibility for physics to address questions about why the initial conditions are the way they are and thus provides a new window into the origins of the universe and the problem of "fine tuning" when it comes to the constant of nature and the form of the physical laws.

The title says it all. This episode is about quasars. I return to my original “training” in astrophysics in order to correct some misconceptions that may have crept into my video titled “The Nexus” here: https://www.youtube.com/watch?v=zpTxBkmr4LE  This episode covers three basic things: The history of the discovery of quasars The physics of quasars Varieties of quasars As with episodes of this kind, it is "image intensive" and although I hope listeners of the audio only will find value - there might be something missed without the images. This episode is also in recognition of the long term work of author Danny Frederick's contribution to the promotion of Popperian epistemology. May Danny be remembered as a philosopher of deep insight into epistemology and a critically rational worldview.

Dive into a thought-provoking exploration of optimism versus pessimism in our understanding of the universe. The discussion spans intriguing concepts like dark energy, consciousness within the multiverse, and the simulation hypothesis. Philosophers weigh in on potential doom scenarios while others offer hopeful perspectives on humanity’s future and technological evolution. The podcast tackles the intersection of AI and human consciousness, questioning what it means to be alive in a rapidly changing world filled with infinite possibilities.
