Robert Sapolsky: The Illusion of Free Will Oct 18, 2023

Show notes

I have been a fan of Robert Sapolsky’s for a long time. He is a creative force, with wide ranging knowledge, from primatology to neuroscience, and he is also a wonderful expositor of science. His previous book, Behave, was a wide ranging exploration of human behavior, at its best and worst. I have been wanting to do a podcast with him for some time, and the launch of his new book, Determined, gave us the opportunity. I got an advanced copy and we recorded this a few weeks ago, so that this podcast could post on the book’s publication date.

Had it been anyone else, I admit I wouldn’t have bothered to go through the book. I have long felt the issue of free will is overplayed. The laws of physics are deterministic, and since biology and chemistry are based on physics, I have never doubted that free will is an illusion, but have also felt that for all intents and purposes the world we live in is indistinguishable from a world with free will, so we should take responsibility for our actions.

As is often the case when reading Robert’s works, my view has now become more nuanced. His book masterfully discusses the neurobiology behind the illusion of free will, what actually interests me the most, and he effectively demolished claims of numerous philosophers, including Dan Dennett and others, that some magic occurs between the level of neurons and the level of the full brain that allows for some uncaused behavior.

Along the way, we are taken on a masterful and fun ride through modern neurobiology. And at the end, Sapolsky confronts the more serious question of crime and punishment in a world where free will is an illusion, and convincingly argues that in a world where bad luck early on gets multiplied throughout ones life, society can far more effectively and honestly deal with crime by abolishing the notion of punishment, replacing it with behaviorally more effective methods.

In our podcast, as we always do, we discussed Sapolsky’s origins. What got him interested in science. How did his 30 years working with primates impact on his view of humans, and more. I found it a fascinating discussion, and I hope you will too.

As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers. Your subscriptions support the non-profit Origins Project Foundation, which produces the podcast. The audio version is available free on the Critical Mass site and on all podcast sites, and the video version will also be available on the Origins Project Youtube channel as well.

Peter Singer: From Animal Liberation to Effective Altruism Oct 07, 2023

Show notes

I have felt privileged to know the remarkable scholar Peter Singer as a friend and colleague for over a decade. We first met, I believe, in the context of atheism, but our discussions have ranged far more broadly, and his impact on my own thinking has been substantial. He and I engaged in a public dialogue in Arizona eight or nine years ago, and preparing for that discussion changed my views about world in many ways. Peter actually had an impact on my life even earlier than that, as when my daughter was very young. The late Katharine Thalberg, who ran the famous Explore Bookstore in Aspen where I often did book signings, and who, along with her spouse Bill Stirling, rang an unsuccessful campaign to ban furs in Aspen, saw how much my then seven year old loved her dogs, and she gave Lilli a copy of Singer’s 1975 book Animal Liberation, to read when she got older. I don’t know if Lilli ever did read it, but she became a vegetarian well before I did.

Peter, perhaps more than anyone else alive, has effectively promoted the cause of animal welfare, coining the term “species-ism” to describe the fact that a proper ethics should include an equal consideration of welfare for not just all people, but all creatures. He has backed up his position with a comprehensive discussion of the disgusting manner in which animals are made to suffer in the context of industrial scale food preparation for humans. That includes not just cattle, pigs, and chickens, but also fish. Whether or not one continues to choose to eat meat, we should all at least be aware of what we are signing on for by doing so.

This year Peter updated Animal Liberation so that it is called Animal Liberation Now, to record the developments that have taken place in the almost 50 years since the book first appeared. His arguments remain as dramatic and clear as they were then, and what I particularly enjoy about Peter is how he combines the philosopher’s tools of analytical logic, with a scientist’s tools of gathering of evidence. The end result is a compelling treatise, and I was thrilled that Peter agreed to sit down again for a comprehensive discussion of the ideas in his book.

We took advantage of this opportunity to talk about Peter’s interest in Effective Altruism, about which he has also written extensively. This is the effort to do the most good in the world by empirically examining both what sorts of charities do the most good for the most people, and also exploring how much of one’s own resources one can readily part with in the process without substantially changing one’s lifestyle. Once again, his discussions may change the way you think, and act.

I hope you enjoy our comprehensive dialogue, for which he generously contributed significant time, as much as I did. And I hope it provokes the same kind of personal reflections for you as it did for me.

And a reminder that The Origins Project Foundation is programming two live events in Southern California museums. Oct 15th, at the Bowers Museum, I will be giving a presentation on my new book, and Oct 17th Brian Keating and I will be recording a joint podcast at the San Diego Air and Space Museum.

Hakeem Oluseyi: An unexpected life in Science, and unpopular truths Sep 20, 2023

Show notes

I confess that Hakeem Oluseyi had not really risen on my radar screen until the last year or two. I was aware of the National Society of Black Physicists, having sometimes gotten notices about is meetings, but, being generally unsupportive of current efforts to compartmentalize scientists by their identity, I hadn’t really paid much notice to it. Then, in one of those ironies that periodically makes one feel better about the vicissitudes of fortune, I learned more about him only after people had attempted to cancel him.

When I read about Hakeem’s brave and impressive campaign to uncover the truth about James Webb after a small but unduly loud group of physicists, whose actions seem to be centered about their mutually celebrated victimhood, argued that the James Webb Space Telescope should be renamed, my interest in him, along with my respect for him, rose considerably.

Prompted by this newfound interest, I read a book he had co-authored, entitled, A Quantum Life: My Unlikely Journey from the Street to the Stars, and I was fascinated by the remarkable transformation of a hillbilly turned drug dealer into an academic. Here was someone who could have reveled in begin a victim by lashing out in hate, but instead was inspired to improve himself and those around him. I decided I wanted to delve deeper into the man, his life, his science, and his recent unfortunate experiences while holding firm to the search for truth in a podcast. It was a fun, and fascinating few hours. Hakeem and I both like to joke as well as tell stories, and we are both serious about the effort to understand nature, and to share our enthusiasm about that effort. I hope the combination of our mutual enjoyment about life and science, along with learning about his own story will inspire, entertain and inform. I certainly enjoyed our discussion and I hope you will as well.

And a reminder that The Origins Project Foundation is programming some live upcoming events, including a live podcast with Richard Dawkins in Birmingham Sept 25th, and two live events in Southern California museums. Oct 15th, at the Bowers Museum, I will be giving a presentation on my new book, and Oct 17th Brian Keating and I will be recording a joint podcast at the San Diego Air and Space Museum.

The Best of the Origins Podcast, Part 1: Sep 01, 2023

Show notes

As promised at the beginning of this month, here is the first of two “Best of” selections from the Origins Podcast. I apologize that this hasn’t come out sooner, but the lazy days of August caught up with all of our production team. In any case, here, on the last day of August (in all US timezones), enjoy this collection of great clips from many of our exciting guests over the first two years of the podcast. These were all recorded before the pandemic and so we were able to travel to talk with my guests at their location, or bring them to our origins studio. As a result, they were all shot with 3 cameras, so the video record is better than one gets on zoom. This video version is available now to paid subscribers, and this audio version is available to all subscribers. A Youtube version will be released later this week. I hope you enjoy them as much as we enjoyed putting this compilation together.

For those of you who are Origins veterans, we will give you a chance to relive the highlights from podcasts with some of the most remarkable scientists, artists, and writers on the planet. For those of you who are newer subscribers this will give you a chance to see some tidbits from some fascinating conversations with fascinating individuals, and perhaps encourage you to explore our backlist for the full discussions.

We will return with new content in September, and will release the second “Best Of” compilation sometime later in the fall. Once again, thanks for your support of Critical Mass, which remains an essential part of allowing The Origins Project Foundation to continue its programming.

Enjoy!

Bart Ehrman: Revelations about Revelation...and more Jul 07, 2023

Show notes

I have admired Bart Ehrman’s writing for more than a decade. I remember how profoundly reading Christopher Hitchens’ God is Not Great reminded me of how little I had really understood about the scriptures. For me, Bart Ehrman took over from there. I recalled reading his 2014 masterpiece How Jesus Became God, which made it clear that the modern Western Interpretation of the Holy Trinity differs significantly from the earliest impressions of Jesus, and moreover that the notion of humans intermingling with deities has a long and checkered history. He also made it clear that the Resurrection, perhaps the cornerstone of Modern Christianity, is highly suspect, based on burial traditions at theme.

I have been trying to work out a time to record a podcast with Bart for some time, and was fortunate that his schedule opened up recently, following the publication of his newest book, Armageddon: What the Bible Really Says About The End. This book provides a detailed analysis of the Book of Revelations, and describes how perhaps the most iconic modern interpretation of End Times, The Rapture, is a modern mythological invention and is itself not even scriptural.

In our dialogue we explored Bart’s own intellectual adventure from fundamentalist youth to Biblical Scholar, from true believer to skeptical historian. We then explored some of the most enlightening aspects of his writing. It was a fascinating, entertaining, and informative discussion, and one that I hope will be widely viewed. I hope you enjoy listening to it as much as we enjoyed recording it.

Martin Rees: If Science is to Save Us, Part 2 Jun 09, 2023

Show notes

This is part two of the second podcast dialogue we are airing with renowned astrophysicist, Astronomer Royal, and former President of the Royal Society, Lord Martin Rees. The first time I sat down with Martin for the Podcast we discussed his life in science, and topics ranging from the state of modern cosmology to the potential conflicts between science and religion (which he views as minimal, and I don’t). Martin’s thinking, and his expertise, go far beyond these topics however. Based on his experience at the Royal Society, as an elected member of the House of Lords, and working with the Center for Existential Risk at Cambridge, Martin has thought carefully about the challenges we face as a society in the 21st century, and how science can be marshaled to help us address these challenges. He has written a new book on the subject called If Science is to Save Us. I thought it would be useful and interesting to sit down with Martin to discuss the ideas he raises there, and our conversation turned out to be so wide-ranging that we are presenting it in two separate episodes of the podcast. I am sure you will find his thoughtful and incisive comments both provocative and inspiring. As always, I benefitted greatly from my conversation with him, and I hope you do as well.

Douglas Murray: From Poetry to Free Speech May 27, 2023

Show notes

I have to say that Douglas Murray reminds me in several ways of my late friend Christopher Hitchens. It is not merely that they are both English, eloquent and well-read. Douglas doesn’t suffer fools gladly, and pulls no punches when necessary. But he is otherwise charming, thoughtful, and willing to enter into respectful intelligent conversations on many topics. Both Douglas and Christopher have been journalists covering dangerous parts of the world, which has helped shape some of their views. Douglas is more conservative, Christopher was in some ways more liberal, but their deep reserve of knowledge combining literature and current events makes listening to either one of them compelling.

I first got to know Douglas through his marvelous book, The Madness of Crowds, a take-off on Charles Murray’s 1841 classic Popular Delusions and the Madness of Crowds, which was “A distillation of some of the most humiliating, terrifying, and confusing things humans have done in collectivity”… treating things like alchemy, haunted houses, and the crusades. Douglas’ book discusses modern craziness, cutting with surgeon-like skill to the heart of issues related to gender, race, identity politics, and of course free speech.

The Madness of Crowds was followed more recently by The War on The West, which took up where the former book left off, dealing with issues ranging from postmodern attacks on the western Canon, attacks on modern science, and more recent ‘Critical Race Theory’ related attacks on modern western society.

I discussed all of these issues with Douglas, but was very pleased to be able to bookend the dialogue, front and back, with a discussion of poetry. He writes a weekly column for Free Press on the virtue and joy of committing great poems to memory, and while I have a limited appreciation and tolerance for poetry in general, there are a few poets, T.S. Eliot, and Rainer Maria Rilke in particular, who I greatly enjoy. It was a pleasure to listen to Douglas recite some favorite lines, and to discuss these sublime subjects with him before and after we dropped down into the muck that comprises the modern culture wars.

I hope you enjoy this discussion as much as I did.

Andrei Linde: Inflation, Multiverses, and all that, from Mr. Eternal Inflation May 14, 2023

Show notes

Andrei Linde is one of the world’s leading cosmological theorists, and is the father of much of Inflationary Cosmology. After Alan Guth developed the original idea of Inflation, Linde, who had been active in this area while working in Moscow, realized a way to make a workable theory out of it, resolving a major problem, called the ‘Graceful Exit’ problem. After that, he made the striking realization that Inflation is inevitable, even in relatively simple theoretical models, and moreover that Inflation will in general be eternal, spawning an infinite number of ‘pocket universes’, as Guth calls them, over an infinite amount of time. While there is much talk about multiverses in the context of string theory, it is the Inflationary Multiverse that is most well motivated, and is currently the most widely accepted picture of the global structure of space and time at the present moment.

Andrei is not only an incredible creative scientist, he is a charming fellow. I have enjoyed my interactions with him since I first met him, about 40 years ago. He is one of a handful of leading Russian scientists who were snapped up by the US after the fall of the Soviet Union. Since arriving in the US he has helped lead a vibrant program in Cosmology and String Theory at Stanford University. I was very excited to finally be able to have a dialogue with Andrei for The Origins Podcast. His teaching schedule precluded doing something each time I had reached out to him in the past, so I felt very fortunate when the stars aligned, or at least his teaching schedule and my recording schedule aligned. What resulted is a fascinating conversation with a remarkable scientist, and a lovely conversationalist. We discussed his own experiences in Russia and then again after emigrating, as well as Inflation, Multiverses, and the state of modern cosmology. I hope you enjoy it as much as I did.

Boldly going where no podcast has gone before: William Shatner; Wonder, Awe, and Questions, Questions... Apr 28, 2023

Show notes

I first met William Shatner a little over 19 years ago when we were filming a TV inspired in part on my book, The Physics of Star Trek. The show was ultimately titled, How William Shatner Changed the World. I am not sure what I expected when I met Bill, but what I got was something completely different. After a brief period during which I felt a bit like I was being auditioned, and which I passed after we filmed a scene in which I was required to use a teleprompter to spout a long series of Star Trek technobabble, we settled in to begin to discuss the world, and I fell a bit in love.

Bill reminded me in many ways of my Uncle, who had long been my favorite relative, and the patriarch of our rather small family. His humor, his confidence, his energy, and his curiosity emerged from the crumbling armor he had originally amassed to potentially protect from him what he may have expected to be a pestering nerd. (And which, for all I know, I may have been).

As the days wore on (I think we spent 3-4 together in total), we began to talk about science and the world, and I was impressed not just with Bill’s intense curiosity and enthusiasm, but his native intelligence. Once again, I guess I had not been prepared for that.

A decade later, and perhaps seven or eight years ago, we spent a week on a Star Trek Cruise together. He of course was the headliner, and I gave some science lectures, and ended up doing two programs on stage with him—one on the program, and one more impromptu. While perhaps billed as a dialogue, the provided an opportunity for Bill to pepper me with questions about all things physics, trade jokes, and overall have a blast. I suspect that is the norm. He invests everything he gets involved in with the same joy, and charm.

So, I was over the moon, when after discussing the possibility of doing The Origins Podcast for over 2 years, Bill finally, in a weak moment, I assume, agreed. It took about 30 seconds for the same sense of fun and joy to take over, a deep friendliness to be transparent, and for Bill to basically take over. From there, I held on to my chair and just tried to enjoy the wild ride. It was fun, and informative. I had 5 pages of questions to ask him, and I managed to sneak in about 3 or 4 questions. Instead the conversation went wherever it went—most often to questions about the Universe—and it was one of the most enjoyable 90 minutes I have spent in awhile. It also gave me a chance to reconnect with Bill, and I don’t plan to wait another decade before doing it again. I hope you enjoy our conversation as much as I did.
