Addressing our nation’s history of racial injustice can be a truly backbreaking endeavor. Race-based affirmative action is usually thought of as one such effort, and colleges and universities often use it in their admissions process. However, affirmative action does seem to lower standards for certain under-represented minorities like Blacks and Hispanics. Should we think of affirmative action as patronizing those minorities, or rectifying the injustices they face? Is affirmative action enough to redress racial injustice, or is it simply the best we can do for the time being? John and Ken welcome Glenn Loury from Brown University, author of The Anatomy of Racial Inequality.

Aldous Huxley explains his conception of the brain as a "reducing valve" of consciousness in his provocative book, The Doors of Perception. His famous experiment with the psychedelic substance mescaline was an attempt to open this valve and expand his capacity for knowledge. However, many drugs and psychedelics today are seen as simply tools for pleasure or the source of bad habits. Do drugs possess the capability to expand our consciousness and provide meaningful insight? Or are they nothing more than a route to empty delirium? Ken and guest co-host Alison Gopnik take a trip with artist, scientist, and founder of the Beckley Foundation, Amanda Feilding.

According to the Treatment Advocacy Center, there are more people living with mental illness in prisons than in psychiatric hospitals across the country. Despite the fact that prisoners can have significant medical needs, healthcare services are often woefully inadequate, which can turn a minor sentence into a death sentence. And for those dying in prison, few receive any hospice or palliative care. So what kinds of patients’ rights should prisoners have? Could improved healthcare in prisons actually reduce recidivism rates? How can we ensure dignity for prisoners in the age of for-profit prisons? John and Ken maintain their dignity with filmmaker Edgar Barens, whose documentary Prison Terminal: The Last Days of Private Jack Hall was nominated for an Academy Award.

We can all agree that helping others is great, a deed worth doing. But devoting too much to helping others – too much time, too many resources get you labelled an oddity, a freak. How much can morality demand of us? Is it good to live as moral a life as possible, or do we lose something – devotion to one’s family, for example – by adhering to extreme moral principles? Can somebody be both fully rational and also a saintly type? John and Ken lend a hand to New Yorker writer Larissa MacFarquhar, author of Strangers Drowning: Grappling with Impossible Idealism, Drastic Choices, and the Overpowering Urge to Help.

The right to bear arms, as guaranteed by the Second Amendment, is at once both distinctly American and highly controversial. Incidents such as the Sandy Hook school shooting force the nation to think hard about how the law should balance gun ownership with the risk these deadly weapons present to society. What kind of right is the right to bear arms, if it is a right at all? What responsibilities ought to come with gun ownership? And what can philosophical thinking contribute to such delicate policy decisions? John and Ken stand their ground with Hugh LaFollette from the University of South Florida, author of The Practice of Ethics.

Jean-Paul Sartre was one of the first global public intellectuals, famous for his popular existentialist philosophy, his works of fiction, and his rivalry with Albert Camus. His existentialism was also adopted by Simone de Beauvoir, who used it as a foundation for modern theoretical feminism. So what exactly is existentialism? How is man condemned to be free, as Sartre claimed? And what’s so hellish about other people? John and Ken speak in good faith with Thomas Flynn from Emory University, author of Sartre: A Philosophical Biography.

The United Nations predicts human population growth will surpass 9 billion around 2050. We know the consequences of overpopulation have the potential to be catastrophic in terms of our continued existence on the planet, with negative environmental effects already visible. Limiting the number of children we have seems like one obvious way to tackle the problem. But is there a moral imperative to limit reproduction? Is having multiple children a right, and if so is it one we should give up for the greater good? What can we do ethically about controlling population? John and Ken have more than a word with Sarah Conly from Bowdoin College, author of One Child: Do We Have a Right to More?

According to a report from the Jubilee Debt Campaign, there are currently 24 countries facing a full-blown debt crisis, with 14 more on the verge. Globally, there is about $200 trillion of debt on the books. Although the poor and disenfranchised of the world play no role in negotiating these loans, in debt crises they usually end up paying the price. So when a country borrows money, who or what is the “economic agent” responsible for taking on the debt? Can traditional economic theory explain why we face debt crises and how we can get out of them? Or do we need a new economic model that dispels some of the myths of the traditional model and offers a more ethical solution to the global debt crisis? John and Ken are held to account with Julie Nelson from the University of Massachusetts Boston, author of Economics For Humans.

Positive psychology is an emerging science that investigates the qualities, attitudes, and practices that enable people to thrive and be happy. So what does this research reveal about human happiness? Are some of us just born with happier dispositions than others? How (if at all) do health, wealth, family relations, and community ties affect our happiness? Do happy people have a better or worse grip on reality than unhappy people? And is happiness something really worth pursuing? John and Ken get happy (scientifically) with Emiliana Simon-Thomas, Science Director of the Greater Good Science Center at UC Berkeley.

“White privilege” has become a buzzword in discussions about racial inequality and racial justice. The call to “check your privilege” appeals to those privileged to acknowledge the various ways they receive special treatment that others don’t. But when white people explicitly acknowledge their privilege, does this do anything to further racial equality? Is talking about “white privilege” just a way to assuage white liberal guilt? Instead of unequal privilege, should we be more focused on equal rights? What kind of theory of justice is required to improve black lives? John and Ken check their privilege with Naomi Zack from the University of Oregon, author of White Privilege and Black Rights: The Injustice of U.S. Police Racial Profiling and Homicide.

The old metaphysical question – why anything exists at all – has perplexed and intrigued humankind for ages. It has long been a question reserved for philosophers, but now some physicists claim to have answered it. Yet these attempts have raised questions of their own: is this even a meaningful question in the first place? Can it be answered by science alone, or is philosophy necessary? And what will answering the question mean for us? John and Ken find something to talk about with Jim Holt, author of Why Does The World Exist: An Existential Detective Story.

Anarchism says there's no need for a state, that it would be better to have a society without central government. Anarchists dislike the often heavy-handed authority that government brings. Yet the dream of the stateless society is not a simple one. How can we have law and order without government? What's involved in a self-governed society, free from authority? And how could we ever peacefully transition from central governance to anarchy? John and Ken question authority with James Martel from San Francisco State University, editor of How Not to be Governed: Readings and Interpretations from a Critical Anarchist Left. This program was recorded live at the Marsh Theater in San Francisco.

Albert Camus is most famous for his existential works of fiction including The Stranger as well as his philosophical essay The Myth of Sisyphus. He led the French resistance press during Nazi Occupation and became one of the youngest Nobel laureates in literature. His contemporary, Hannah Arendt, described him as head and shoulders above the other intellectuals. How does Camus' philosophy of Absurdism compare and contrast with Sartre's popular existentialism, especially in their conceptions of freedom? What political and philosophical issues of his time were he deeply involved in, and what relevance does his thinking still hold for the problems of contemporary life? John and Ken remain sensible with Robert Zaretsky from the University of Houston, author of A Life Worth Living: Albert Camus and the Quest for Meaning.

Whether it's making donations and signing petitions online, or using social media to highlight political causes, cyber-activism has never been easier. With a few clicks, we can make our voices heard around the globe. But who's listening, and is anything actually changing? Does cyber-activism mobilize real-world action on the ground, or does it reduce political engagement to simple mouse-clicking and ultimately threaten the subversive nature of change? John and Ken get active with Lucy Bernolz from the Stanford Center on Philanthropy and Civil Society, co-author of Disrupting Philanthropy: Technology and the Future of the Social Sector. This program was recorded live at the Marsh Theater in San Francisco.

Democratic systems of government are supposed to reflect the interests of ordinary citizens, and not some shadowy political elite. But more and more, we see the influence of big money and special interest groups in so-called democratic politics, while income inequality and voter suppression grow. With millions convinced that politicians don_x0090_t speak for them, is there a "crisis of representation" in the US? Are these problems a result of political decay in our institutions, or is democracy in trouble everywhere? How can we achieve an efficient and prosperous democracy in which the average citizen is truly represented? Should we consider a radically different system of government? John and Ken keep calm with renowned political scientist Francis Fukuyama, author of Political Order and Political Decay: From the Industrial Revolution to the Globalization of Democracy. This program was recorded live on the Stanford University campus.

The Diagnostic and Statistical Manual is the primary reference catalog for mental health illnesses. But whereas a medical textbook will show you the picture of a broken bone or a tumor, leaf through the DSM and you will find just one thing: lists of symptoms. Who creates these lists, and based on what criteria? Do such lists really capture the nature of a mental illness? What does it mean to be a disease of the mind versus a disease of the body? Does our classification system construct mental illness, or does it reveal underlying facts from genetics or neuroscience? John and Ken diagnose the issues with Jerome Wakefield from NYU, co-author of The Loss of Sadness: How Psychiatry Transformed Normal Sorrow Into Depressive Disorder.

The number of chronically hungry people in the world is over 800 million, yet developed countries are facing health challenges from rising rates of obesity. The growing problems of food security and water scarcity seem an issue of distribution rather than availability. But other factors also influence the status of food and water security worldwide. So where does the problem with food and water security lie? Do developed countries _ or any other entities or individuals _ have any moral obligations to ensure a global network of water and food security? What practical, policy-oriented action can fulfill any moral obligations that might exist? John and Ken grab a bite with Tim Benton, Professor of Population Ecology at the University of Leeds and UK Champion for Global Food Security.

Best known for his work Being and Time, Martin Heidegger has been hailed by many as the greatest philosopher of the twentieth century. He has also been criticized for being both nearly unreadable and a Nazi. Yet there is no disputing his seminal place in the history of Western thought. So what did Heidegger mean when he wrote about world, being, and time? What significance does he still hold as a thinker today, especially as a philosopher of modern technology? Should we even read the works of a Nazi? John and Ken are present and ready with Thomas Sheehan from Stanford University, author of Making Sense of Heidegger: A Paradigm Shift.

Humans have an amazing capacity to communicate. By uttering sounds we are able to convey meaning to those around us. These noises we make take on properties they mean certain things, they are true or false, etc. Some animals also use forms of language: bees, for example, use dances and pheromones to communicate with each other. What gives these signals words and movements their linguistic meaning? How is it possible to communicate complex propositions simply by making sound? John and Ken cut through the noise with celebrated philosopher of language John Searle, in a program recorded live at the Marsh Theatre in Berkeley.
