Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and Ideas

Change is scary. But sometimes it can all work out for the best. There's no guarantee of that, however, even when the change in question involves the introduction of a powerful new technology. Today's guest, Daron Acemoglu, is a political economist who has long thought about the relationship between economics and political institutions. In his most recent book (with Simon Johnson), Power and Progress: Our Thousand-Year Struggle Over Technology and Prosperity, he looks at how technological innovations affect the economic lives of ordinary people. We talk about how such effects are often for the worse, at least to start out, until better institutions are able to eventually spread the benefits more broadly.

The philosophy of mathematics would be so much easier if it weren't for infinity. The concept seems natural, but taking it seriously opens the door to counterintuitive results. As mathematician and philosopher Joel David Hamkins says in this conversation, when we say that the natural numbers are "0, 1, 2, 3, and so on," that "and so on" is hopelessly vague. We talk about different ways to think about the puzzles of infinity, how they might be resolved, and implications for mathematical realism.

Just like with physics, in biology it is perfectly possible to do most respectable work without thinking much about philosophy, but there are unmistakably foundational questions where philosophy becomes crucial. When do we say that a collection of matter (or bits) is alive? When does it become an agent, capable of making decisions? What are the origins of morality and altruistic behavior? We talk with one of the world's leading experts, Samir Okasha, about the biggest issues in modern philosophy of biology.

Which is more intelligent, ChatGPT or a 3-year old? Of course this depends on what we mean by "intelligence." A modern LLM is certainly able to answer all sorts of questions that require knowledge far past the capacity of a 3-year old, and even to perform synthetic tasks that seem remarkable to many human grown-ups. But is that really intelligence? François Chollet argues that it is not, and that LLMs are not ever going to be truly "intelligent" in the usual sense -- although other approaches to AI might get there.

For those of us who are not dualists, the mind arises from our physical bodies -- mostly the brain, but the rest of the body has a role to play. And yet it remains tempting to treat the mind as a thing in itself, disconnected from how the body is doing. Ellen Langer is a psychologist who is one of the foremost researchers on the idea of mindfulness -- the cognitive skill of paying to one's thoughts, as well as to one's external environment. Her most recent book is The Mindful Body: Thinking Our Way to Chronic Health. We talk about how our state of mind can effect the functions of our body, sometimes in surprising ways.

We claim to love all of our children, friends, and students equally. But perhaps deep down you assign a ranking to them, from favorite to not-so-favorite. Ranking and quantifying people is an irresistible human tendency, and modern technology has made it ubiquitous. In this episode I talk with sociologist Kieran Healy, who has co-authored (with Marion Fourcade) the new book The Ordinal Society, about how our lives are measured and processed by the technological ecosystem around us. We discuss how this has changed how relate to ourselves and the wider world.

String theory, the current leading candidate for a theory of quantum gravity as well as other particles and forces, doesn't connect directly to the world we see. It's possible that there is a large landscape of possible states of theory, with the hope that one of them represents our universe. The existence of a landscape implies the existence of a corresponding swampland -- universes that are not compatible with string theory. I talk with Cumrun Vafa, a respected physicist and originator of the swampland program, about how we might use constraints on what kinds of physics are compatible with string theory to make predictions about cosmology and other experimental regimes.

In the conversation we refer to a famous diagram representing different ten-dimensional string theories, as well as 11-dimensional M-theory, as different limits of an underlying fundamental theory.

The Earth's climate keeps changing, largely due to the effects of human activity, and we haven't been doing enough to slow things down. Indeed, over the past year, global temperatures have been higher than ever, and higher than most climate models have predicted. Many of you have probably seen plots like this. Today's guest, Gavin Schmidt, has been a leader in measuring the variations in Earth's climate, modeling its likely future trajectory, and working to get the word out. We talk about the current state of the art, and what to expect for the future.

Publication week! Say hello to Quanta and Fields, the second volume of the planned three-volume series The Biggest Ideas in the Universe. This volume covers quantum physics generally, but focuses especially on the wonders of quantum field theory. To celebrate, this solo podcast talks about some of the big ideas that make QFT so compelling: how quantized fields produce particles, how gauge symmetries lead to forces of nature, and how those forces can manifest in different phases, including Higgs and confinement.

Modern biology is advancing by leaps and bounds, not only in understanding how organisms work, but in learning how to modify them in interesting ways. One exciting frontier is the study of tiny "robots" created from living molecules and cells, rather than metal and plastic. Gizem Gumuskaya, who works with previous guest Michael Levin, has created anthrobots, a new kind of structure made from living human cells. We talk about how that works, what they can do, and what future developments might bring.

Humanity itself might be the hardest thing for scientists to study fairly and accurately. Not only do we come to the subject with certain inevitable preconceptions, but it's hard to resist the temptation to find scientific justifications for the stories we'd like to tell about ourselves. In his new book, The Invention of Prehistory, Stefanos Geroulanos looks at the ways that we have used -- and continue to use -- supposedly-scientific tales of prehistoric humanity to bolster whatever cultural, social, and political purposes we have at the moment.

Science is enabled by the fact that the natural world exhibits predictability and regularity, at least to some extent. Scientists collect data about what happens in the world, then try to suggest "laws" that capture many phenomena in simple rules. A small irony is that, while we are looking for nice compact rules, there aren't really nice compact rules about how to go about doing that. Today's guest, Leslie Valiant, has been a pioneer in understanding how computers can and do learn things about the world. And in his new book, The Importance of Being Educable, he pinpoints this ability to learn new things as the crucial feature that distinguishes us as human beings. We talk about where that capability came from and what its role is as artificial intelligence becomes ever more prevalent.

Einstein's theory of general relativity has been our best understanding of gravity for over a century, withstanding a variety of experimental challenges of ever-increasing precision. But we have to be open to the possibility that general relativity -- even at the classical level, aside from any questions of quantum gravity -- isn't the right theory of gravity. Such speculation is motivated by cosmology, where we have a good model of the universe but one with a number of loose ends. Claudia de Rham has been a leader in exploring how gravity could be modified in cosmologically interesting ways, and we discuss the current state of the art as well as future prospects.

Technology is changing the world, in good and bad ways. Artificial intelligence, internet connectivity, biological engineering, and climate change are dramatically altering the parameters of human life. What can we say about how this will extend into the future? Will the pace of change level off, or smoothly continue, or hit a singularity in a finite time? In this informal solo episode, I think through what I believe will be some of the major forces shaping how human life will change over the decades to come, exploring the very real possibility that we will experience a dramatic phase transition into a new kind of equilibrium.

When it comes to social change, two questions immediately present themselves: What kind of change do we want to see happen? And, how do we bring it about? These questions are distinct but related; there's not much point in spending all of our time wanting change that won't possibly happen, or working for change that wouldn't actually be good. Addressing such issues lies at the intersection of philosophy, political science, and social dynamics. Sahar Heydari Fard looks at all of these issues through the lens of complex systems theory, to better understand how the world works and how it might be improved.
