What direction does time point in? None, really, although some people might subconsciously put the past on the left and the future on the right, or the past behind themselves and the future in front, or many other possible orientations. What feels natural to you depends in large degree on the native language you speak, and how it talks about time. This is a clue to a more general phenomenon, how language shapes the way we think. Lera Boroditsky is one of the world’s experts on this phenomenon. She uses how different languages construe time and space (as well as other things) to help tease out the way our brains make sense of the world.Support Mindscape on Patreon.Lera Boroditsky received her Ph.D. in cognitive psychology from Stanford University.

This is a special episode of Mindscape, thrown together quickly. Many thanks to Tara Smith for joining me on short notice. Tara is an epidemiologist, and a great person to talk to about the novel coronavirus (and its associated disease, COVID-19) pandemic currently threatening the world. We talk about what viruses are, how they spread, and a lot of the science behind virology and pandemics. We also take a practical turn, talking about what measures (washing hands, social distancing, self-isolation) are useful at combating the spread of the virus, and which (wearing masks) are probably not. Then we look to the future, to ask what the endgame here is; Tara suggests that the kind of drastic measure we are currently putting up with might last a long time indeed.Tara Smith received her Ph.D. in microbiology from the University of Toledo. She is currently Professor of Epidemiology at the Kent State University College of Public Health. She has researched and written extensively about diseases such as ebola and MRSA. She is an active science communicator, and writes regular columns for SELF magazine.Web siteKent State web pageGoogle Scholar publicationsWikipediaAmazon author pageTwitterSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

“What good is half a wing?” That’s the rhetorical question often asked by people who have trouble accepting Darwin’s theory of evolution by natural selection. Of course it’s a very answerable question, but figuring out what exactly the answer is leads us to some fascinating biology. Neil Shubin should know: he is the co-discoverer of Tiktaalik Roseae, an ancient species of fish that was in the process of learning to walk and breathe on land. We talk about how these major transitions happen — typically when evolution finds a way to re-purpose existing organs into new roles — and how we can learn about them by studying living creatures and the information contained in their genomes.Support Mindscape on Patreon.Neil Shubin received his Ph.D. in organismic and evolutionary biology from Harvard University. He is currently the the Robert Bensley Distinguished Service Professor and Associate Dean of Biological Sciences at the University of Chicago.

If you tell me that one of the world’s leading neuroscientists has developed a theory of how the brain works that also has implications for the origin and nature of life more broadly, and uses concepts of entropy and information in a central way — well, you know I’m going to be all over that. So it’s my great pleasure to present this conversation with Karl Friston, who has done exactly that. One of the most highly-cited neuroscientists now living, Friston has proposed that we understand the brain in terms of a free energy principle, according to which our brains are attempting to model the world in such a way as to minimize the amount of surprise we experience. It’s a bit more complicate than that, but I think we made great headway in explicating some very profound ideas in a way that should be generally understandable.Support Mindscape on Patreon.Karl Friston received his medical degree from King’s College Hospital, London. He is currently Professor at the Institute of Neurology, University College London, and Wellcome Principal Research Fellow and Scientific Director of the Wellcome Trust Centre for Neuroimaging. Among his major contributions are statistical parametric mapping, voxel-based morphometry, and dynamical causal modeling. He is a Fellow of the Royal Society, of the Academy of Medical Science, and of the Royal Society of Biology. Among his awards are the Young Investigators Award in Human Brain Mapping, the Minerva Golden Brain Award, the Weldon Memorial Prize, the Charles Branch Award, and the Glass Brain Award for human brain mapping.Web pageGoogle Scholar publicationsTalk on “I Am, Therefore I Think”Article on “The Free-Energy Principle: A Unified Brain Theory?”WikipediaSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Anyone who has read histories of the Cold War, including the Cuban Missile Crisis and the 1983 nuclear false alarm, must be struck by how incredibly close humanity has come to wreaking incredible destruction on itself. Nuclear war was the first technology humans created that was truly capable of causing such harm, but the list of potential threats is growing, from artificial pandemics to runaway super-powerful artificial intelligence. In response, today’s guest Martin Rees and others founded the Cambridge Centre for the Study of Existential Risk. We talk about what the major risks are, and how we can best reason about very tiny probabilities multiplied by truly awful consequences. In the second part of the episode we start talking about what humanity might become, as well as the prospect of life elsewhere in the universe, and that was so much fun that we just kept going.Support Mindscape on Patreon.Lord Martin Rees, Baron of Ludlow, received his Ph.D. in physics from University of Cambridge.

It’s hard to make decisions that will change your life. It’s even harder to make a decision if you know that the outcome could change who you are. Our preferences are determined by who we are, and they might be quite different after a decision is made — and there’s no rational way of taking that into account. Philosopher L.A. Paul has been investigating these transformative experiences — from getting married, to having a child, to going to graduate school — with an eye to deciding how to live in the face of such choices. Of course we can ask people who have made such a choice what they think, but that doesn’t tell us whether the choice is a good one from the standpoint of our current selves, those who haven’t taken the plunge. We talk about what this philosophical conundrum means for real-world decisions, attitudes towards religious faith, and the tricky issue of what it means to be authentic to yourself when your “self” keeps changing over time.Support Mindscape on Patreon.L.A. (Laurie) Paul received her Ph.D. in philosophy from Princeton University. She is currently professor of philosophy and cognitive science at Yale University. She has worked extensively on causation, the philosophy of time, mereology, and transformative experience.

Nations generally want their economies to be rich, robust, and growing. But it’s also important to person to ensure that wealth doesn’t flow only to a few people, but rather that as many people as possible can enjoy the benefits of a healthy economy. As is well known, the best way to balance these interests is a contentious subject. On one side we might find free-market fundamentalists who want to let supply and demand set prices and keep government interference to a minimum, while on the other we might find enthusiasts for very strong government control over all aspects of the economy. Suresh Naidu is an economist who has delved deeply into how economic performance affects and is affected by other notable social factors, from democracy to revolution to slavery. We talk about these, as well as how concentrations of economic power in just a few hands — monopoly and its cousin, monopsony — can distort the best intentions of the free market.Support Mindscape on Patreon.Suresh Naidu received his Ph.D. in economics from the University of California, Berkeley.

The Greek statesman Demosthenes is credited with saying “I am a citizen of the world,” and the idea that we should take a cosmopolitan view of our common humanity is a compelling one. Not everyone agrees, however; in the words of former British Prime Minister Theresa May, “If you are a citizen of the world, you are a citizen of nowhere.” On the other side of the political spectrum, groups who share a feature of identity — race, ethnicity, gender, sexuality, and others — find it useful to band together to make political progress. Kwame Anthony Appiah is a leading philosopher and cultural theorist who has thought carefully about the tricky issues of cosmopolitanism and identity. We talk about how identities form, why they matter, and how to negotiate the difficult balance between being human and being your particular self.Support Mindscape on Patreon.Kwame Anthony Appiah received his Ph.D. in philosophy from Cambridge University. He is currently Professor of Philosophy and of Law at New York University. He is the author of numerous academic books as well as several novels.
