Philosophy Talk Starters

More at https://www.philosophytalk.org/shows/shakespeares-outsiders. Over 400 years after his death, Shakespeare is still widely regarded as the greatest dramatist of all time. His many plays tackle questions about power, influence, identity, and moral and social status. His characters—be they villains or heroes—are often disdained because of their race, religion, class, disability, or gender. So what do Shakespeare’s plays reveal about identity and status in his time? How might they shed light on who we include and who we exclude today? Could Shakespearian dramas have more in common with modern day soap operas than we think? Ray and guest-host Adrian Daub go inside with David Sterling Brown from Trinity College, author of "Shakespeare's White Others."

More at https://www.philosophytalk.org/shows/mind-sharing. Mind reading might sound like the stuff of science fiction. But in philosophy and psychology, mind reading is something that human beings do whenever we try to guess what another person is thinking. Could it be that people are also natural born mind sharers, unconsciously shaping our behavior to be understood by others? How do we change or exaggerate our actions when others are present? And how can we use these insights to communicate better with our loved ones? Josh and Ray share their mind(s) with Julian Jara-Ettinger, Director of the Computational Social Cognition Lab at Yale University.

More at https://www.philosophytalk.org/shows/margaret-cavendish. Margaret Cavendish was a writer of poetry, philosophy, polemics, histories, plays, and utopian fiction. She employed many different genres as a way to overcome access barriers for women and build an audience for her subversive philosophical ideas. So, what was so radical about Cavendish's views? Why did she think all matter, even rocks, was at least partially rational? And how did she anticipate the term "epistemic injustice" 400 years before it was coined? Josh and Ray explore the life and thought of Margaret Cavendish with Karen Detlefsen from the University of Pennsylvania, co-editor of "The Routledge Handbook of Women and Early Modern European Philosophy."

More at https://www.philosophytalk.org/shows/2024-dionysus-awards. What movies of the past year challenged your assumptions and made you think about things in new ways? Josh and guest co-host Jeremy Sabol present our annual Dionysus Awards for the most thought-provoking movies of 2023, including: • Best Film about Social Justice that Wonders What Makes a Good Film about Social Justice • Most Disturbing Exploration of a Female Criminal Who Thinks She May Be Innocent • Most Moving Film (or TV show!) about Difficult Choices

More at https://www.philosophytalk.org/shows/im-yunjidang. 8th-century Korean philosopher Im Yunjidang was the first Confucian to argue for women’s equality in matters of morality and to claim that women, just like men, can be sages. She also argued that it isn't just what you do that matters morally—it's also how you decide. So what does it mean to be a sage and how does someone become one? How did Im Yunjidang use traditional Confucian texts to argue for women's spiritual equality? And what did she think was important when it comes to making difficult moral choices? Josh and Ray explore her life and thought with Hwa Yeong Wang from Duke Kunshan University, editor of "Korean Women Philosophers and the Ideal of a Female Sage: The Essential of Writings of Im Yungjidang and Gang Jeongildang." Part of the "Wise Women" series, supported by a grant from the National Endowment for the Humanities.

More at https://www.philosophytalk.org/shows/can-ai-help-us-understand-babies. Artificial intelligence is everywhere in our day-to-day lives and our interactions with the world. And it's made impressive progress at a variety of visual, linguistic, and reasoning tasks. Does this improved performance indicate that computers are thinking, or is it just an engineering artifact? Can it help us understand how children acquire knowledge and develop language skills? Or are humans fundamentally different from machines? Josh and Ray decode the babble with Michael Frank, Professor of Human Biology at Stanford University and Director of the Symbolic Systems Program.

More at https://www.philosophytalk.org/shows/20th-anniversary-quiz-night. Philosophy Talk made its radio debut on August 20, 2003 with a live pilot on KALW San Francisco and weekly broadcasts beginning in January 2004. To celebrate two decades on the air, in November 2023 we held our first-ever Quiz Night. Longtime listeners and first-time fans filled KALW's popup space in downtown San Francisco as Director of Research Laura Maguire ran eight teams through the gauntlet of a philosophical pub quiz. In this special 20th anniversary episode, Josh and Ray (who participated in the quiz as regular contestants) revisit the drama and intellectual derring-do from that evening with their guest quiz-taker, host emeritus John Perry.

More at https://www.philosophytalk.org/shows/american-futures. When Philosophy Talk co-founder Ken Taylor passed away in 2019, he was working on a manuscript titled Farewell to the Republic We Once Dreamed of. Was Ken right to think the American experiment is on the verge of collapse? Are we heading for authoritarian rule, a national divorce, or even a civil war? Or could better days be on the horizon? In Ken’s honor, Josh and Ray devote their end-of-year special to probing the future of the American republic with Barbara Walter from UC San Diego, Tamsin Shaw from New York University, and Rob Reich from Stanford University.

More at https://www.philosophytalk.org/shows/impossible-worlds. Philosophers often speculate about possible worlds: ways that things could be. Some of them also believe in impossible worlds: ways that things couldn't be. Are impossible worlds places where strange things happen, or descriptions, or abstract objects, or something else entirely? How can you describe an impossibility without contradicting yourself? Could we imagine worlds where even the laws of logic are different? Josh and Ray imagine the unimaginable with Koji Tanaka from the Australian National University, author of "Logically Impossible Worlds."

More at www.philosophytalk.org/shows/awe-wonder. René Descartes said that the purpose of wonderment is “to enable us to learn and retain in our memory things of which we were formerly unaware.” He also said that those who are not inclined to wonder are “ordinarily very ignorant.” So what exactly is wonder, and how is it different from awe? Is wonder at the core of what drives us to search for novel insights? And can we suffer from an excess of wonderment? Josh and Ray stand in awe of Helen de Cruz from St. Louis University, author of "Wonderstruck: How Wonder and Awe Shape the Way We Think" (forthcoming).

More at https://www.philosophytalk.org/shows/mary-astell. Mary Astell (1666–1731) was an English philosopher and writer who advocated for equal rights for women. While she described marriage as a type of “slavery,” she was also a staunch conservative who claimed that women who did marry should accept subordination to their husbands. So what was Astell's vision for the education of women? How did she reconcile her seemingly conflicting views on marriage? And why did philosopher John Locke criticize her views on natural law? Josh and Ray explore her life and thought with Allauren Forbes from McMaster University. Part of the "Wise Women" series, supported by a grant from the National Endowment for the Humanities.

More at www.philosophytalk.org/shows/zhuangzi. Zhuangzi, the 4th-century-BCE Chinese philosopher, was arguably the most important figure in Taoism. He believed that a person’s ideal relationship to the world was to "be one with ten thousand things." So how is someone supposed to achieve this ideal? What is at the core of Zhuangzi's conception of the good life? And how could contemporary western readers benefit from his way of thinking? Josh and Ray welcome back Paul Kjellberg from Whittier College, editor of "Essays on Skepticism, Relativism, and Ethics in The Zhuangzi."

More at https://www.philosophytalk.org/shows/referring-world. On December 2, 2019, Ken Taylor announced that he finally had “an almost complete draft” of a book he had been writing for years. “I think I'll pour a glass of wine to mark the occasion, before plunging back into the work that is still to be done,” he wrote. Tragically and unexpectedly, he died later that same day. Thanks to the hard work and dedication of some colleagues, his book, "Referring to the World: An Opinionated Introduction to the Theory of Reference," has just been published. In this special episode, Josh and Ray discuss Ken’s ideas about reference with USC philosopher Robin Jeshion, who helped bring the book to fruition.

More at https://www.philosophytalk.org/shows/elisabeth-bohemia. Princess Elisabeth of Bohemia (1618–1680) is best known for her correspondence with René Descartes. In her letters, she articulated a devastating critique of his dualist theory of mind, in particular on the impossibility of mind-body interaction. So what was Elisabeth's own position on the nature of mind? What can we ascertain about her moral and political concerns based on her various correspondences? And how are her ideas still relevant to current debates in philosophy? Josh and Ray explore Elisabeth's life and thought with Lisa Shapiro from McGill University, editor of "The Routledge Handbook of Women and Early Modern European Philosophy." Part of our series "Wise Women," supported by a grant from the National Endowment for the Humanities.

More at https://www.philosophytalk.org/shows/can-architecture-be-political. It’s common to judge a piece of architecture based on its functional and aesthetic values, and how the two might complement or compete with one other. It’s less common to judge architecture based on its political values. But can’t a building’s design also express a political viewpoint? Why are different styles of architecture associated with different ideologies? And can a historical edifice's social purpose change over time? Josh and Ray build a foundation with Vladimir Kulić from Iowa State University, editor of "Toward a Concrete Utopia: Architecture in Yugoslavia, 1948–1980."

More at https://www.philosophytalk.org/shows/are-we-living-simulation. With rapid advances in Virtual Reality technology and the like, it’s now possible for us to become absorbed in completely made-up worlds. We might wonder how soon it will be till we reach a point where VR is so good, we can’t tell it apart from the real world. But what if we’ve already reached that point? How would we know if we were currently living in a simulated reality, or are there always telltale signs? And if we were in a simulation, what difference would it make—pragmatically or morally—in how we live our lives and treat other people? Josh and Ray don't fake it with David Chalmers from NYU, author of "Reality+: Virtual Worlds and the Problems of Philosophy."

More at https://www.philosophytalk.org/shows/weird-wants. Philosophers from Thomas Aquinas to Elizabeth Anscombe have claimed that wanting something means seeing the good in it. Even if what you want is bad overall, like procrastinating on important work, you can still desire it for its positive qualities. But don't we sometimes want things because of their badness, not in spite of it? Isn't there joy in doing something totally pointless, or even in breaking the rules? And is it really impossible, logically speaking, to want to be bad? Josh and Ray unravel our weird wants with Paul Bloom from the University of Toronto, author of "The Sweet Spot: The Pleasures of Suffering and the Search for Meaning."

More at https://www.philosophytalk.org/shows/making-better-world. Some philosophers think that morality boils down to one idea: we should make the world better for everyone. But who counts in "everyone"—babies, animals, future people? How can we tell what makes the world better for others? And in an uncertain world, how can anyone gauge the effects of their actions? Josh and Ray try to save the world with acclaimed Princeton philosopher Peter Singer, author of "Ethics in the Real World: 90 Essays on Things That Matter."

More at https://www.philosophytalk.org/shows/hypatia-alexandria. Hypatia of Alexandria, late antiquity public figure and scholar, made significant contributions to mathematics, philosophy, and astronomy. Her embrace of Neoplatonism was seen as such a threat to the political elite in Alexandria that she was murdered by a mob of Christians. So what made her ideas so dangerous and revolutionary for her time? As a woman in Ancient Egypt, how did she exert power over her own narrative? And should she really be considered a "martyr" for philosophy? Josh and Ray explore Hypatia's life and thought with Edward Watts, Professor of History at UCSD and author of "Hypatia: The Life and Legend of an Ancient Philosopher."

More at www.philosophytalk.org/shows/mexican-philosophy. From early feminist Sor Juana Inés de la Cruz to existentialist Emilio Uranga, from Indigenous thought to theorists of aesthetic utopia, Mexican philosophy is full of fascinating figures with brilliant insights. What can we learn from them today about belief, desire, freedom, morality, and education? And do Mexican philosophers speak with one voice or in a complicated harmony, stretching across the centuries? Josh and Ray travel through space and time with Manuel Vargas from UC San Diego, author of "Building Better Beings: A Theory of Moral Responsibility."

What books should thoughtful people read this summer? Josh and Ray talk to the authors and editors of new and recent books as they compile their annual Summer Reading List: • Michael Schur, creator of TV's "The Good Place" and author of "How to Be Perfect: The Correct Answer to Every Moral Question" • Lori Gruen, Professor of Philosophy at Wesleyan University and co-editor of "The Good It Promises, The Harm It Does: Critical Essays on Effective Altruism" • Gabriella Safran, Professor of Slavic Languages and Literatures at Stanford University and author of "Recording Russia: Trying to Listen in the Nineteenth Century"

More at https://www.philosophytalk.org/shows/what-gender. Gender is a controversial topic these days, but people can't seem to agree about what gender is. Is it an inner identity, a biological fact, or an oppressive system? Should we respect it or resist it? Should it even be a thing? Josh and guest-host Blakey Vermeule question gender with regular co-host Ray Briggs, co-author of "What Even Is Gender?"

More at https://www.philosophytalk.org/shows/can-art-save-us. The world is facing an unprecedented environmental crisis, and we urgently need good ways to address it. Courageous politicians would help, of course, as might scientific innovations. But how much of the problem is a failure of imagination? Could the arts help us see our way out of the problem? How can literature, painting, and movies redraw the landscape in our minds? Josh and Ray imagine a conversation with Harriet Hawkins, Professor of Human Geography and Co-Director of the Centre for GeoHumanities at Royal Holloway, University of London.

More at https://www.philosophytalk.org/shows/true-contradictions. If you want to tell the truth, you shouldn’t contradict yourself—that’s just common sense. A suspect who was home on the night of the crime can’t have been elsewhere, and whatever the weapon, we can rule out the hypothesis that it was both a candlestick and not a candlestick. But there are philosophers who claim we shouldn’t overgeneralize based on murder mysteries: some contradictions are true. Could a badly written law make the dastardly deed both legal and illegal? Do mathematical paradoxes create weird things that both do and don’t exist? If we embrace contradictions, will we still be able to tell the difference between truth and falsehood? Josh and Ray embrace contradiction with Graham Priest from the City University of New York, author of "Doubt Truth to Be a Liar."

More at https://www.philosophytalk.org/shows/power-prediction. You’re standing at the top of a mountain, surveying the vast landscape below. The information your senses take in flows to your brain, which processes it to create a representation of the scene. Or does it? What if instead of directly perceiving the world around us, the brain is more like a prediction machine that hallucinates a picture of the world? If that were the case, could we still rely on the so-called “evidence of our senses”? Would it be possible to avoid unpleasant sensory experiences, like hunger or pain, by simply changing our expectations? How can we harness the power of the predictive brain? Josh and and Ray predict a fascinating conversation with Andy Clark from the University of Sussex, author of "The Experience Machine: How Our Minds Predict and Shape Reality."

More at https://www.philosophytalk.org/shows/derek-parfit-and-your-future-self. The works of Derek Parfit (1942-2017) have had a profound influence on how philosophers understand rational decision-making, ethics, and personal identity. At the heart of Parfit's thinking are questions about how you should relate to your future self, and whether you should treat your future self any differently than other future people. So why does Parfit argue that it's wrong to place a special value on your own survival? What would it take to value others in the way that you value yourself? And how might we harness Parfit's insights to make the world a better place? Josh and Ray's future selves welcome back Parfit's former student David Edmonds, author of "Parfit: A Philosopher and His Mission to Save Morality."

More at https://www.philosophytalk.org/shows/philosophy-smell. When philosophers think about human perception, they tend to focus on vision and turn their noses up at olfaction, the sense of smell. So what insights can we gain about perception, thought, and language by focusing on olfaction? How culturally variable is the ability to distinguish one scent from another? Do we need to learn certain concepts before we can detect certain odors, or can our noses pick up things we can’t yet name? And why do we have so many words to describe what we see, yet so few to describe what we smell? Josh and Ray sniff out the details with experimental psychologist and olfaction expert Asifa Majid from the University of Oxford, in an episode generously sponsored by the Stanford Symbolic Systems Program.

More at https://www.philosophytalk.org/shows/2023-dionysus-awards. What movies from the past year challenged your assumptions and made you think about things in new ways? Josh and guest co-host Jeremy Sabol present our annual Dionysus Awards for the most thought-provoking movies of 2022, including: • Meatiest Meditation on Mortality and Meaning (in the British Isles) • Coolest Contemplation of Complicated Comeuppances • Combo Cup for Greatest Genrepalooza

More at https://www.philosophytalk.org/shows/cancel-culture. Revoking support or a platform from someone who is perceived to have behaved badly has recently been dubbed “cancel culture.” Many complain that this pervasive practice promotes mob mentality and stifles free speech. But is "cancel culture" a real phenomenon, or has it become an overused and meaningless concept? Is publicly censuring others for something they've done or said itself a form of free speech? And is there a moral difference between “canceling” public figures and “canceling” ordinary folks who get caught on tape behaving badly? Josh and Ray give a platform to Adrian Daub from Stanford University, author of "Cancel Culture Transfer."

More at https://www.philosophytalk.org/shows/why-trust-science. According to a recent survey conducted by the Pew Research Center, the number of Americans who trust in science is steadily declining. While politicization is partly to blame, another reason may be that the “truths” of science seem to shift endlessly. So why should we trust science? Is it still reliable, even if it doesn’t seem to settle on a single truth? And what can be done to increase the general public’s confidence in medicine, climate research, or statistics? Josh and Ray rely on Ann Thresher from Stanford University, co-author of "The Tangle of Science Reliability Beyond Method, Rigour, and Objectivity."

More at https://www.philosophytalk.org/shows/examined-year-2022. What happened over the last twelve months that challenged our assumptions and made us think about things in new ways? • The Year in Developed Nations at War with Tamsin Shaw from NYU, author of "Nietzsche's Political Skepticism" • The Year in Supreme Court Controversy with Bernadette Meyler from the Stanford Law School, author of "Theaters of Pardoning" • The Year in Deep Space Photography with Nick Riggle from the University of San Diego, author of "This Beauty: A Philosophy of Being Alive"

More at http://philosophytalk.org/shows/how-relevant-jesus. Some people think Jesus was the son of God, though many who are skeptical about that still think he was a great moral teacher. But if we really knew what Jesus would think about moral issues that he didn't confront while he lived – abortion, terrorism, euthanasia, gay marriage or the destruction of old-growth redwoods – would it be that helpful? Would his moral vision have any implications for these issues? Ken and John discuss the moral philosophy of Jesus and its contemporary relevance with Andrew Fiala, Director of the Ethics Center at Fresno State University and author of "What Would Jesus Really Do? The Power and Limits of Jesus' Moral Teachings."

More at https://www.philosophytalk.org/shows/thinking-conspiracy-theorist. The moon landing was faked! JFK Jr. is still alive! Finland doesn’t exist! Conspiracy theories of all sorts have been gaining traction, thanks partly to the ease with which they spread online. But what makes someone more inclined to believe in vast conspiracies? Are marginalized groups who have been lied to by authorities more likely to be distrustful of official narratives? Or do common cognitive biases make all humans susceptible to this kind of thinking? And what can we do to combat the spread of conspiracy theorizing? Ray and guest-host Blakey Vermeule hatch a plot with Christopher French from the University of London, co-author of "Anomalistic Psychology: Exploring Paranormal Belief and Experience."

More at https://www.philosophytalk.org/shows/search-prousts-philosophy. Marcel Proust’s In Search of Lost Time challenges us to think hard about what we can know, who we really are, why memory matters, and how we can find enchantment in a world without God. But some might wonder why we need a 3,000 page novel to do that. Are there things a novel can do that a philosophy book can’t? Does it take a great person to produce great art? And why read Proust in the twenty-first century? Ray and guest-host Blakey Vermeule find a spot on the guestlist for Josh and his new book, "The World According to Proust."

More at https://www.philosophytalk.org/shows/how-create-virtuous-leaders. Ancient philosophers like Socrates and Plato believed that an education focused on developing good character could create virtuous leaders who work for the people, not their own benefit. Nowadays, though, it seems too many politicians are power hungry, corrupt, and out of touch. So how do we train our leaders to be more virtuous? Is good character something that can be taught? And what can we learn from the Ancients about how we can each lead an excellent life? Josh and Ray virtuously welcome back Massimo Pigliucci from the City College of New York, author of "The Quest for Character: What the Story of Socrates and Alcibiades Teaches Us about Our Search for Good Leaders."

More at https://www.philosophytalk.org/shows/liberty-and-justice-who. Many democracies are founded on the ideals of 18th- and 19th-Century British Liberalism: the idea that human beings deserve the right to self-government because we are born free, equal, and capable of rationality. Yet Liberalism was used to justify colonialism, which deprived people around the world of the right to govern themselves. How could a political philosophy that claims to be pro-freedom be used to take freedom away from so many people? Was Liberalism misunderstood, or were its moral flaws built-in from the beginning? How can we design a political philosophy that liberates everyone, not just the citizens of a few wealthy and powerful nations? Josh and Ray talk liberally with Uday Singh Mehta from the CUNY Graduate Center, author of "Liberalism and Empire: A Study in Nineteenth-Century British Liberal Thought."

More at https://www.philosophytalk.org/shows/climate-change-and-collective-action. Catastrophic storms, floods, droughts, and fires are increasing in frequency all over the globe, and the polar ice caps are melting twice as fast as initially predicted. Despite this, we struggle to take meaningful action that could avert—or at least mitigate—the impending climate disaster. So why is it so hard for people to coordinate on doing the right thing, when the threat is so urgent? Is it a failure of human rationality, a lack of will, or something else? And how do we overcome the obstacles we face and take collective action that will make a real difference? Josh and Ray collect their thoughts with Kieran Setiya from MIT, author of "Life Is Hard: How Philosophy Can Help Us Find Our Way."

More at https://www.philosophytalk.org/shows/who-owns-culture. Fashion designers, musicians, and Halloween costume wearers have been accused of engaging in cultural appropriation. In some cases, the alleged appropriator is quick to apologize; in others, they defend their actions as a way of appreciating a different culture. So why is cultural appropriation such a morally fraught issue? Is there a clear-cut way to tell whether we’re exploring or exploiting? And can we come up with principles that allow artists to be inspired while also allowing communities to hold on to what is theirs? Josh and Ray mix it up with Dominic Lopes from the University of British Columbia, author of "Aesthetic Injustice: A Cosmopolitan Theory" (forthcoming).

More at https://www.philosophytalk.org/shows/effective-altruism. Most people agree that it's good to help others, but philosophers disagree about how much good we need to do, and for whom. Effective altruists claim that you have a moral obligation to do the most good you can—even when that means setting aside the needs of your nearest and dearest in order to help strangers. So what does morality demand of us? Are we justified in caring more about our own communities than faraway strangers? And is it ever okay to pursue a personal project when you could be helping others? Josh and Ray demand much of Theron Pummer from the University of St. Andrews, author of "The Rules of Rescue: Cost, Distance, and Effective Altruism" (forthcoming).

More at https://www.philosophytalk.org/shows/what-political-inequality. We all know our society is economically unequal: some people have more money and resources than others. But equality isn't just a matter of who has which things. Political equality involves respect and participation in the political process—but those aren't resources that can be divided up like pie. So what is political equality in the first place? How do we know when we've achieved it? And can we prevent politics from being an elite activity concentrated among the educated and wealthy? Josh and Ray push for equality with Margaret Levi, Director of the Center for Advanced Study in the Behavioral Sciences at Stanford University and co-author of "A Moral Political Economy: Present, Past, and Future."

More at https://www.philosophytalk.org/shows/optimism-rational. When the odds are against you, believing in yourself can be a source of strength—but it seems to require a cavalier disregard for the evidence. So is optimism a rational way to improve your life, or an irrational kind of wishful thinking? Will hope now just lead to disappointment later? Where should we set our expectations, and where should we teach our children to set theirs? Josh and Ray tackle their hopes and fears with Jennifer Morton from the University of Pennsylvania, author of "Moving Up without Losing Your Way: The Ethical Costs of Upward Mobility."

More at https://www.philosophytalk.org/shows/summer-reading-list-banned-books-edition. The American Library Association reports that last year 1,597 books were challenged or removed from libraries, schools, and universities, a record high number (compared to 273 books in 2020). Most of the challenged or removed books deal with themes relating to race or sexuality and gender, and challenges come from both the right and the left. What are the implications for your thought-provoking summer reading? Josh and Ray talk to Stanford English professor Paula Moya about attempts to remove Toni Morrison's "The Bluest Eye" from schools; activist Chaz Stevens about his crusade to ban the Bible from Florida schools; and Jennifer Ruth & Michael Bérubé about their new book, "It's Not Free Speech: Race, Democracy, and the Future of Academic Freedom."

More at https://www.philosophytalk.org/shows/changing-face-antisemitism. Antisemitism is an old problem with roots that reach back to medieval Europe. While earlier forms focused more on religious bigotry, antisemitism in the modern period became increasingly racialized and politicized. So what is the connection between older ideas about Jews and Judaism, and contemporary antisemitic tropes and stereotypes? How are conspiratorial fears about Jewish invisibility and global control related to the emergence of finance capitalism? And what can history teach us about how to confront antisemitism today? Josh and Ray ask historian Francesca Trivellato from the Institute for Advanced Study, editor of "Jews in Early Modern Europe" (forthcoming), in a program recorded live at the Stanford Humanities Center.

More at https://www.philosophytalk.org/shows/scandalous-truth-about-memoir. A memoir is a personal narrative written about a pivotal time in the author’s life. While the story is told from a particular perspective, the events recounted are supposed to be fact, not fiction. But what exactly counts as truth in memoir? Is the distinction between “literal truth” and “emotional truth” just a way of shirking responsibility for fabricating falsehoods? What other ethical responsibilities does the memoirist have—for example, when it comes to exposing other people’s secrets? And why should anyone read—or write—memoirs in the first place? Josh and Ray take a trip down memory lane with Helena de Bres from Wellesley College, author of "Artful Truths: The Philosophy of Memoir."

More at https://www.philosophytalk.org/shows/what-ideology. Political polarization seems to be deepening, both in the U.S. and around the globe. Some believe that the rise of ideology is to blame for growing polarization. But can increased polarization really be attributed to ideology? What is exactly is ideology, and how is it different from dogma? Is ideology a kind of political or philosophical thinking? And how might our understanding of ideology affect how we practice politics? Josh and Ray ideate with Marius Ostrowski from the European University Institute, author of "Ideology (Key Concepts)."

More at https://www.philosophytalk.org/shows/what-would-kant-do. German idealist and moral philosopher Immanuel Kant is probably best known for his "Categorical Imperative," which says that you should act following moral rules you could rationally support as universal law. In other words, do only what you would have everyone else do. But are Kant's rules really a good guide to action? Does he have anything to say about things people confront in everyday life, like friendship, manners, or gossip? Is Kant overly optimistic about our capacity to use reason and choose freely? Or was he right that rationality is the key to moral progress? Josh and Ray do right by Karen Stohr from Georgetown University, author of "Choosing Freedom: A Kantian Guide to Life."

More at https://www.philosophytalk.org/shows/2022-dionysus-awards. What movies of the past year challenged our assumptions and made us think about things in new ways? Josh and guest co-host Jeremy Sabol present our annual Dionysus Awards for the most thought-provoking films of 2021, including: • Best Attempt to Redeem 80+ Years of Questionable Ethics • Best Film about Complicated Mothers Telling Uncomfortable Truths • Best Adapted Novel about Trauma, Marginalization, Self-Deception AND the Gap Between Appearance and Reality

More at https://www.philosophytalk.org/shows/why-poetry-matters. Some people say they find poetry impenetrable. Yet readership is increasing: in a 2017 survey, the National Endowment for the Arts found that nearly 12% of adults in the US had read poetry in the last year. So what explains the enduring appeal of poetry as an art form? Are there any limits to who counts as a poet, or what counts as poetry? And what makes a poem good anyway? Josh and Ray wax lyrical with Nobel Prize-winning poet Louise Glück, author of "American Originality: Essays on Poetry."

More at https://www.philosophytalk.org/shows/metoo-retribution-accountability-and-justice. The #MeToo movement exposed how pervasive sexual harassment and abuse are, and how rare it is for perpetrators to be held accountable. Although some recent high profile cases have resulted in convictions, more often punishment is meted out by public shaming. So why is it so difficult to hold sexual abusers legally responsible for their actions? Is social retribution a way to achieve some form of justice in lieu of criminal proceedings? And how do we move forward to find love and acceptance when there are still such great asymmetries of power? Josh and Ray tackle the issues with Janine Benedet from the UBC School of Law.

More at https://www.philosophytalk.org/shows/righteous-rage. Stoic philosopher Seneca wrote that anger is a form of madness. Other philosophers share this suspicion, viewing anger as a destructive emotion that leads to cruel and vengeful acts. But don't certain kinds of injustice, like the murders of black and brown people in the US, deserve our rage? What's the difference between righteous indignation and a destructive urge for revenge? And how can activists channel their anger toward political good? Josh and Ray keep their cool with Myisha Cherry from UC Riverside, author of "The Case for Rage: Why Anger is Essential to Anti-racist Struggle."

More at https://www.philosophytalk.org/shows/marcus-aurelius. Marcus Aurelius was a 2nd century Roman emperor and Stoic philosopher. He is most famous for his Meditations, which was written as a private guide to himself on how to live a life where virtue is the only good and vice the only evil. So how do we figure out how to live a truly Stoic life? What’s the relationship between the wellbeing of an individual and the interest of the larger community? And what can we learn from Marcus about developing mental resilience when confronted with fear, suffering, or pain? Josh and Ray stay calm with Rachana Kamtekar from Cornell University, author of "Plato's Moral Psychology: Intellectualism, the Divided Soul, and the Desire for Good."

More at https://www.philosophytalk.org/shows/could-robots-be-persons. As we approach the advent of autonomous robots, we must decide how we will determine culpability for their actions. Some propose creating a new legal category of “electronic personhood” for any sufficiently advanced robot that can learn and make decisions by itself. But do we really want to assign artificial intelligence legal—or moral—rights and responsibilities? Would it be ethical to produce and sell something with the status of a person in the first place? Does designing machines that look and act like humans lead us to misplace our empathy? Or should we be kind to robots lest we become unkind to our fellow human beings? Josh and Ray do the robot with Joanna Bryson, Professor of Ethics and Technology at the Hertie School of Governance.

What happened over the past 12 months that challenged our assumptions and made us think about things in new ways? • The Year in Political Insurrection with former co-host and current Stanford Dean Debra Satz • The Year in Space Tourism with Brian Green from Santa Clara University, author of "Space Ethics" • The Year in the Post-Pandemic Workplace with Quill Kukla from Georgetown University, author of "City Living: How Urban Spaces and Urban Dwellers Make One Another" ...because the un-examined year is not worth reviewing!

More at https://www.philosophytalk.org/shows/what-can-virtual-reality-actually-do. VR transports users into all kinds of different realities, some modeled on the real world, others completely invented. Though still in its infancy, the technology has become so sophisticated, it can trick the brain into treating the virtual experience as real and unmediated. So what is the most prudent way to employ this cutting edge technology going forward? Could VR help solve real world problems, like implicit bias or the climate crisis? And as the technology becomes more widely available, are there potential dangers we ought to be seriously thinking about? Josh and Ray strap on their headsets with Jeremy Bailenson, Director of the Virtual Human Interaction Lab at Stanford, and author of "Experience on Demand: What Virtual Reality Is, How It Works, and What It Can Do."

More at https://www.philosophytalk.org/shows/should-all-ages-be-equal. Age determines a lot about your position in society—what activities you can do, what benefits you can access, and what rights and responsibilities you have. While it seems appropriate to treat people at different stages of life differently, we also consider certain kinds of unequal treatment unjust. So when should we treat people of different ages differently? And when does it become ageism or age discrimination? When does a disadvantage for an age group turn into injustice against a generation? Josh and Ray act their age with Juliana Bidadanure from Stanford University, author of "Justice Across Ages: Treating Young and Old as Equals."

More at https://www.philosophytalk.org/shows/social-lives-robots. Machines might surpass humans in terms of computational intelligence, but when it comes to social intelligence, they’re not very sophisticated. They have difficulty reading subtle cues—like body language, eye gaze, or facial expression—that we pick up on automatically. As robots integrate more and more into human life, how will they figure out the codes for appropriate behavior in different contexts? Can social intelligence be learned via an algorithm? And how do we design socially smart robots to be of special assistance to children, older adults, and people with disabilities? Josh and Ray read the room with Elaine Short from Tufts University, co-author of more than 20 papers on human-robot interaction, including "No fair!! An interaction with a cheating robot."

More at https://www.philosophytalk.org/shows/frege-and-language-reason. At the end of the 19th Century, the German philosopher Gottlob Frege invented a new language, based on mathematics, designed to help people reason more logically. His ideas have had a lasting impact on philosophy, math, computer science, and the study of artificial intelligence. And many of the questions that influenced his thinking are still hotly debated today: How much does language influence the thoughts you can think? Could there be a way of speaking that taps into deep philosophical insights about the nature of reality? What's the relationship between math and logic? Josh and Ray try to make sense of Frege with host emeritus John Perry, author of "Frege's Detour: An Essay on Meaning, Reference, and Truth."

More at https://www.philosophytalk.org/shows/akan-philosophy. The Akan people of West Africa have developed a system of metaphysics, epistemology, and moral philosophy with a special focus on personhood. For the Akan, their conception of a person is not just a matter of theoretical interest—it has far reaching practical implications for their social institutions and communal practices. So what exactly is the Akan notion of personhood, and how is it rooted in Akan traditional culture? How does the Akan emphasis on the social nature of personhood promote trust, cooperation, and a sense of responsibility to the community? And can this communal perspective help restore cultural identity in a postcolonial Africa? Josh and Ray welcome Ajume Wingo from the University of Colorado Boulder, author of "Veil Politics in Liberal Democratic States."

More at https://www.philosophytalk.org/shows/mysterious-timelessness-math. Math is a really useful subject—at least, that's what your parents and teachers told you. But math also leads to scenarios, like Zeno's paradoxes, that seem to inspire skepticism. So why do we believe in math and rely on it to build bridges and spaceships? How can anyone discover the secrets of the universe by simply scribbling numbers on a piece of paper? Is math some kind of magic, or does it have a more ordinary explanation? And could math be culturally relative, or are its concepts timeless and universal? Josh and Ray add things up with Arezoo Islami from SF State University.

More at https://www.philosophytalk.org/shows/ethics-awesomeness. The word “awesome” once meant inspiring extreme fear or dread. Nowadays it’s mostly used as a general purpose exclamation of approval. So when we describe a person as awesome, are we saying that they exemplify some general form of excellence? Or are awesome people those who break specific social norms to generate moments of creative expression and social connection? Would the world be a better place if we all aimed to be more awesome and less sucky? Josh and Ray stand in awe of Nick Riggle from the University of San Diego, author of "On Being Awesome: A Unified Theory of How Not to Suck."

More at https://www.philosophytalk.org/shows/microaggressions. Microaggressions are small comments or questions that may be insulting or hurtful to another person because of their race, gender, sexuality, and so on. Some people consider microaggressions to be a phantom symptom of political correctness and a further sign that society has become “soft,” while others see them as a problematic way of normalizing bigotry. So how do microagressions compare to other types of moral harms? Do they add up to structural oppression, and if so, how are we to assign individual culpability? Josh and Ray engage calmly with Lauren Freeman from the University of Louisville, co-editor of "Microaggressions and Philosophy."

More at https://www.philosophytalk.org/shows/your-brain-literature. Cognitive science has revolutionized our understanding of the brain and how it functions. Researchers have even used fMRI to detect differences in the way people engage with literature. But can contemporary science really teach us anything about how novels, poems, and movies work? Do new understandings of the unconscious help us appreciate the brilliant magic tricks that writers pull off? And could a better picture of mental imagery inspire novelists to write differently? Josh and Ray pick the brain of Stanford neuroscientist David Eagleman, author of "Livewired: The Inside Story of the Ever-Changing Brain."

More at https://www.philosophytalk.org/shows/summer-reading-list-2021. As some parts of our lives return to some kind of normal, Josh and Ray ask authors and philosophers about what's been on their summer reading lists. • Cory Doctorow on "Making Hay," his short story in "Make Shift: Dispatches from the Post-Pandemic Future" • Helen De Cruz from Saint Louis University, co-editor of "Philosophy Through Science Fiction Stories: Exploring the Boundaries of the Possible" Plus Michaela Bronstein from the Stanford English deparment on Richard Wright's recently-published "The Man Who Lived Underground."

More at https://www.philosophytalk.org/shows/nonduality-and-oneness-being. Some branches of Hindu philosophy propose that reality is nondual in nature. Such schools of thought—called advaita schools, from a Sanskrit word meaning “not two”—see the material world either as an aspect of ultimate reality (“Brahman”) or as a mere illusion. So how do we make sense of the appearance of variety in a metaphysics of oneness? Is there room for individual selves within advaita philosophy? What can be known? And what possible sources of knowledge are there in a nondual epistemology? Josh and Ray become one with Elisa Freschi from the University of Toronto, author of "Duty, Language, and Exegesis in Prābhākara Mīmāṃsā."

More at https://www.philosophytalk.org/shows/vienna-circle. The Vienna Circle was a group of early twentieth-century philosophers, mathematicians, logicians, and scientists, best known for developing the theory of scientific knowledge called logical positivism. Although positivism as a project has been largely abandoned, the group's ideas continue to have profound influence on contemporary philosophy of science. So what philosophical theories were proposed by the Vienna Circle? How might the socio-political circumstances of their time have shaped their radical ideas? And how did their ideas aim to shape politics? Josh and Ray ask David Edmonds from the University of Oxford, author of "The Murder of Professor Schlick: The Rise and Fall of the Vienna Circle."

More at https://www.philosophytalk.org/shows/disinformation-and-future-democracy. The 2020 election and startling events that followed show that the US is as polarized as ever. Not only is there fundamental disagreement over values and goals, but people can’t seem to agree on the most basic, easily verifiable facts, like who actually won. With so many seemingly living in an alternative reality, how do we continue the business of democracy together? Should we adopt paternalistic policies towards fellow citizens who are so profoundly divorced from truth? And does our current plight suggest that the project of liberal democracy is failing? Ray and guest co-host (emeritus) John Perry stay informed about their guest, attorney and political analyst Dean Johnson, co-host of KALW's Your Legal Rights.

More at https://www.philosophytalk.org/shows/montaigne-and-art-essay. French thinker Michel de Montaigne invented a whole new genre in which to do philosophy: the essay. But in his use of that form, Montaigne repeatedly digresses and contradicts himself. So why did he think the essay was a good medium for philosophy? What impact did Montaigne’s invention have on his own philosophical work, and on the centuries of thought that followed? Are there particular forms of writing that help us live a more philosophical life? The philosophers live their best life with Cécile Alduy from Stanford University, author of "The Politics of Love: Poetics and Genesis of the "Amours" in Renaissance France (1549-1560)."

More at https://www.philosophytalk.org/shows/2021-dionysus-awards. After a year in which "entertainment" took on a whole new meaning, what were the movies that challenged our assumptions and made us think about things in new ways? Josh and guest co-host Jeremy Sabol talk to philosophers and listeners as they present our eighth annual Dionysus Awards for the most thoughtful films of the past year, including: • Best Film Painting a World Without Men • Best Picture That Packs All of American History Into One Room • Trippiest Investigation of Identity (That Probably Should Have Ended Sooner)

More at https://www.philosophytalk.org/shows/what-masculinity. Strong, in control, and stoic—these are traits of the ideal masculine man. Men who fail to conform to this ideal are often penalized, particularly if they are men of color, queer men, working-class men, or men with disabilities. So how do we create different visions of masculinity that make room for all kinds of men? Should we abandon the idea of masculinity altogether, or would that be throwing out the baby with the bathwater? Which models of masculinity will bring us closer to gender justice in the 21st century? The philosophers man their mics with Robin Dembroff from Yale University, author of "Real Men on Top: The Metaphysics of Patriarchy" (in progress).

More at https://www.philosophytalk.org/shows/what-has-replaced-freud. Although the concept that we can have thoughts and desires hidden from consciousness can be traced back to antiquity, it was Freud who truly popularized it in the twentieth century. Now Freud’s theory of the unconscious mind has mostly been abandoned for being unscientific and lacking in empirical evidence. So what has replaced it? Are newer theories that reference “automatic systems” or “implicit attitudes” any more scientific than Freud’s? And why is so much research about the unconscious mind being conducted in business schools? Josh and Ray are quite conscious of their guest, Blakey Vermeule from Stanford University, author of "The New Unconscious: A Literary Guided Tour."

More at https://www.philosophytalk.org/shows/rhetoric-big-tech. Big Tech is known for its "disruption" of established industries and changing fundamental aspects of our lives from shopping and delivery to communication and transit. While many welcome these changes, there are also worries about privacy, fairness, and deregulation. So how do tech companies think about what it is they are doing and what justifies it? Who are their philosophical sources, and do they use them responsibly? What role does New Age thinking, Ayn Rand, Martin Heidegger, and even Samuel Beckett play in shaping the rhetoric of big tech? Josh and Ray debug the code with Adrian Daub from Stanford University, author of "What Tech Calls Thinking: An Inquiry into the Intellectual Bedrock of Silicon Valley."

More at https://www.philosophytalk.org/shows/democracy-numbers. The United States prides itself on being “the world’s greatest democracy,” which adheres to the principle, “one person, one vote.” Despite this, its elections are often highly contentious—presidents can be elected after losing the popular vote, there is widespread gerrymandering and voter purging, and not everyone has equal representation in the Senate. So what can we do to make elections in the US more fair? And how do we decide what counts as fair in the first place? Is there some test or algorithm we can use to determine equal representation? Josh and Ray watch the polls with Moon Duchin from Tufts University, Director of the Metric Geometry and Gerrymandering Research Group.

More at https://www.philosophytalk.org/shows/minds-and-matter. Everything that seems to have a mind also has a body made of flesh and blood. But if we look at the diversity of animals found in the world, we find a huge variety of species that perceive and interact with the world in very different ways. Is there something all these species have in common? Are neurons and ganglia required, or can evolution generate consciousness in different ways? What can the study of evolutionary biology tell us about the nature of the mind? Josh and Ray sail away with Peter Godfrey-Smith from the University of Sydney, author of "Metazoa: Animal Life and the Birth of the Mind."

More at https://www.philosophytalk.org/shows/arts-all. When we think of “real” art, we often think of expensive, highbrow pieces that are displayed in museums and galleries, and critiqued by the elite. In fact, people commonly lament that they don’t know enough about art to truly understand or appreciate the works that they encounter. So should art aim to be accessible to everyone? Or is it ever okay to sacrifice accessibility for other competing aims that art can pursue? Do artists have a duty to make their work more available or accessible in other ways? Josh and Ray paint their masterpiece with Catharine Abell from the University of Oxford, author of "Fiction: A Philosophical Analysis."

More at https://www.philosophytalk.org/shows/are-we-all-blame. It’s easy to identify the pressing issues facing our world today, but it’s much more difficult to assign responsibility for them. Often the blame is placed on collectives — on entire governments, nations, and societies. But does the responsibility truly all fall to them? How can we identify precisely whose fault it is, for example, that we are experiencing climate change, or that hate crimes occur, or that there is a gender wage gap? Or do we as individuals hold a certain amount of responsibility for such pervasive, systemic issues? Josh and Ray avoiding pointing fingers with Maron Smiley from Brandeis University, author of "Moral Responsibility and the Boundaries of Community."

More at http://philosophytalk.org/shows/hegel. Georg Wilhelm Friedrich Hegel is without doubt one of the most influential philosophers of all time. He has, however, been largely ignored by American "analytic" philosophers of the twentieth century. John in particular, and Ken to a lesser extent, don't know nearly as much about Hegel and his philosophy as they should. They will be lively if somewhat obtuse students for Allen Wood, Stanford's resident expert on virtually all aspects of modern philosophy, when Philosophy Talk goes to the bookshelf and pulls down the big volumes of Hegel's collected works.

More at http://philosophytalk.org/shows/nature-imagination. A lot of our thinking, and even our perception, has to do not only with what is, but what might be, and what would have been. That is, the imagination is an important part of our intellectual life. And learning to use our imaginations without losing sight of reality is part of growing up. What is the imagination, and what led Mother Nature to make it such an important part of our make-up? John and Ken discuss the imagination with Alison Gopnik, a leading scholar in the field of children’s learning.

More at http://philosophytalk.org/shows/philosophical-summer-reading-list. Are there some philosophers, philosophies, or philosophical issues you want to bone up on over the Summer? Hegel's "Phenomenology of the Spirit" probably isn't a very good choice to take to the beach, but there are a lot of readable, beach-friendly classics and non-classics to add philosophical depth to your Summer Reading. Ken and John discuss some of their favorites and pass on suggestions from Philosophy Talk guests.

More at http://philosophytalk.org/shows/justice-across-boundaries. Philosophical conceptions of justice have most often been directed at the nature of a just state. But many contemporary issues of justice reach across boundaries. Are our immigration policies fair and just? Can a just state invade another state in order to outfit it with a more just government? Can we defend economic policies that improve the lives of our citizens but an adverse impact on economies abroad? John and Ken look beyond with Martha Nussbaum from the University of Chicago, author of "Frontiers of Justice: Disability, Nationality, Species Membership."

More at http://philosophytalk.org/shows/what-art. Anything someone wants to call art? Or are there some objective criteria, that not every instance of paint smeared on canvas and not every murder mystery meets? What are the main philosophies of art? Are any of them plausible? John and Ken talk about the nature of art with Alexander Nehamas from Princeton University.

More at http://philosophytalk.org/shows/philosophy-and-law. With what right do governments make and enforce laws? To what extent are citizens obligated to obey the law, even if a law is unjust? John and Ken talk about philosophy and the law with Jules Coleman from Yale University.

More at http://philosophytalk.org/shows/value-truth. The pursuit of truth is often thought to be "intrinsically" valuable. Scientists and philosophers, who eschew religious rationales for their life's work, take the pursuit of truth to be obviously a worthwhile enterprise. But what's so great about truth? Sure, it's good to know what's for lunch, or the nature of the disease that plagues you, but is there any intrinsic or instrumental value in knowing how far away the farthest stars are? Or whether Milton's greatest works were written while he had a headache? Or what the next layer of basic particles are like? Truth telling on Philosophy Talk with Simon Blackburn, author of "Truth: A Guide."

More at http://philosophytalk.org/shows/suicide. Taking human life is wrong. But what if it is one's own life? Is suicide worse or less bad than murder? Is it wrong at all? Can suicide be rational? How about helping another commit suicide? The Philosophers discuss the metaphysics and morality of taking one's own life with Michael Cholbi from Cal Poly Pomona, author of "Suicide: The Philosophical Dimensions."

More at http://philosophytalk.org/shows/what-are-number. Plato claimed that numbers exist in some mind-independent abstract heaven. Nominalists claim that there is no such heaven. Clearly, we can't see, hear, taste or feel numbers. But if there are no numbers what is mathematics all about? John and Ken count on a great discussion with Gideon Rosen from Princeton University, co-author of "A Subject With No Object: Strategies for Nominalistic Interpretation of Mathematics."

More at http://philosophytalk.org/shows/existentialism. Being and Nothingness, the for-itself and the in-itself, bad faith, and the existential predicament; these Existentialist concepts were central to the philosophical scene in Europe and America after World War II. Join the Philosophers as they examine the ideas of Existentialism with Lanier Anderson from Stanford University.

More at http://philosophytalk.org/shows/science-humor. Being funny isn't easy. Figuring out what makes things funny is even harder. Still, a number of psychologists (e.g., Freud) and philosophers (e.g., Bergson) have tried. Now computer scientists are trying to learn enough about humor to construct programs that can write good jokes; maybe an artificial stand-up comedian is on the way. Ken and John discuss the art, philosophy and science of humor with Tony Veale, an Irish computer scientist who knows a good joke when his program produces one.

More at http://philosophytalk.org/shows/marriage-and-monogamy. Monogamy is traditional in most cultures, and it is the law throughout America since Utah gave up polygamy to acquire statehood. Is there any philosophical basis for favoring monogamy over polygamy? Or any reasons grounded in clear empirical facts or social needs? With a looming shortage of females relative to males in large parts of Asia, is it time to question this traditional assumption about marriage? John and Ken remain faithful to their guest, renowned anthropologist Helen Fisher, author of "Why We Love: The Nature and Chemistry of Romantic Love."

More at http://philosophytalk.org/shows/web-du-bois. Sociologist, historian, philosopher, editor, writer, and activist, W.E.B. DuBois was one of the most influential intellectuals of the twentieth century. The first African-American Ph.D. from Harvard University, DuBois died in Ghana after having renounced his American citizenship. In between he co-founded the NAACP and wrote "The Souls of Black Folk" (1903) as well as a number of other influential books that had a decisive impact on the development of African-American culture in the twentieth century. John and Ken discuss DuBois' life and thought with Lucius Outlaw from Vanderbilt University, author of "On Race and Philosophy."

More at http://philosophytalk.org/shows/legislating-values. To legislate is to choose, and choices are made for the sake of values. But what values should, and which values do, guide our legislators? And why? Does the majority always rule? What attention must be paid to deeply held religious values? Or deeply held secular values? Ken and John discuss these issues with Representative Anna Eschoo (D-Cal).

More at http://philosophytalk.org/shows/philosophy-science. Is philosophy the queen of the sciences, with the job of synthesizing, interpreting and evaluating the results of the particular sciences? Or should we adopt John Locke's conception of philosophy as a handmaiden to science: clarifying concepts, definitions and assumptions? During the twentieth century the discipline of the philosophy of science emerged as a central part of philosophy. Ken and John discuss some of the leading ideas and projects involved in this branch of philosophy with Peter Godfrey-Smith from Harvard University.

More at http://philosophytalk.org/shows/intelligent-design. Is there any reason to think the cause or causes of order in the universe bear an even remote analogy to human intelligence? Even if they did, would that mean these intelligent causes had the benevolence and sense of justice required of a Christian God? Is this whole issue one of science, religion, or philosophy? These questions, considered by Hume, have now become the focus of a national debate. The philosophers discuss intelligent design with Daniel Dennett, Director of the Center for Cognitive Studies at Tufts University, author of books on consciousness, evolution, and freedom.

More at www.philosophytalk.org/shows/progress-and-environment Does the value of preserving our environment conflict with the development of a world community in which all enjoy the fruits of human progress? Is the environment important intrinsically, or only as a source of pleasure and other goods for human beings? Ken and John discuss these and other issues with Terry Tamminen, Cabinet Secretary to California Governor Schwarzenegger, and an environmental activist.

More at www.philosophytalk.org/shows/existence-god The question of whether or not God exists is profoundly fascinating and important. What are the proofs of the existence of God? How can one prove that God does not exist? Join us as John and Ken explore issues such as religious experience, the Bible, evil, eternity, the origin of the universe, design, and the supposed connection between morality and the existence of God with Walter Sinnott-Armstrong from Dartmouth College.

More at http://philosophytalk.org/shows/kant Immanuel Kant introduced the human mind as an active originator of experience rather than just a passive recipient of perception. How has his philosophy influenced the world after him? John and Ken dig into the brilliantly active mind of Kant with Peter Gilgen from Cornell University, editor of "Back to Kant II: The Fate of Kant in a Time of Crisis."

More at www.philosophytalk.org/shows/freedom-speech The Constitution grants the freedom of speech to every citizen. Journalists value it more than anything else. Should the freedom of speech be unlimited? Would unlimited freedom of speech do more good or bad to our society? Would limited freedom of speech impact the monitoring power of news media and therefore threaten our society? John and Ken discuss the philosophy behind the freedom of speech with Geoff Stone from the University of Chicago Law School.

More at www.philosophytalk.org/shows/friendship Who do we call friends? Do we need friends out of love for others or for ourselves? Is a life with friends necessarily a better life? Ancient philosophers, such as Aristotle, wrote extensively on the topic. John and Ken examine just what friendship means in the modern life with their friend, Martha Nussbaum, Professor of Law and Ethics, University of Chicago.

More at www.philosophytalk.org/shows/language-fiction What are we talking about when we talk about Sherlock Holmes or Santa Claus? Something that doesn't exist? Something that exists only in the mind? Something that exists only in a fictional or imaginary world? Are statements about fictional objects true? Is there a distinction between literal truth and "fictional truth?" John and Ken uncover the facts about fiction with Joshua Landy from Stanford University.

More at http://philosophytalk.org/shows/george-berkeley. Berkeley founded and defended idealism, the doctrine that there is not a material world; reality is the orchestration of ideas in minds, nothing more. He influenced Hume, Mill, Russell, and many other philosophers. John and Ken explore Berkeley's ideas with David Hilbert from the University of Illinois at Chicago.
