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 r...

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 c...

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 themse...

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 st...

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...

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...

More at www.philosophytalk.org/shows/time-summer-reading. When John and Ken began shopping around their idea for a philosophy-on-the-radio show nearly 20 years ago, many believed it would never work, let alone stay on the air. Nearly two decades later, the program that questions everything (except your intelligence) has hit 500 episodes -- just in time for current co-hosts Josh and Ray to spend ou...

More at www.philosophytalk.org/shows/ken-taylor-tribute. The Philosophy Talk team is deeply saddened by Ken Taylor's untimely passing this month. Ken was the show's co-founder, longtime co-host, chief cheerleader, and guiding light. In this special episode, co-hosts Josh Landy and Debra Satz, along with host emeritus and co-creator John Perry, remember their colleague and friend. They also hear fr...

More at https://www.philosophytalk.org/shows/foreign-aid-or-injury. Many of us might think that developed nations should lead the effort to end global poverty. But decades of foreign aid—from governments and non-governmental organizations—has failed to produce sustainable growth in the developing world. How can we empower local actors to become self-sufficient rather than dependent on foreign aid?...

More at https://www.philosophytalk.org/shows/does-science-over-reach. We've all heard the phrase, "You can't argue with science." Appealing to scientific fact as a way to settle a question makes sense given the amazing advancements science has brought us in understanding how the world works. But should we take the accomplishments of science as evidence for scientism—the view that science is the be...

https://www.philosophytalk.org/shows/radical-markets. Many people think that growing inequality, the rise of populism and nativism, and the decay of democratic institutions all have the same cause—the overreach of markets. The solution, they believe, is to limit the market through regulation. But what if rather than shrinking the market, the answer lies in expanding the market? Is it possible that...

More at https://www.philosophytalk.org/shows/repugnant-markets. We might ban buying or selling horse meat in the US not for the protection of horses, but because we find it morally repugnant. Yet this moral repugnance is clearly not universal, and on some level may even be arbitrary, given France's attitude toward horse meat. What role, if any, should moral repugnance play in determining the rules...

More at https://www.philosophytalk.org/shows/faith-and-humility. Some would argue that faith requires that one blindly—rather than rationally— believe. Faith in one ‘true’ religion often entails rejection of all others. Given this, can there ever be humility when it comes to religious faith? How unwavering should the faithful be when it comes to their religious convictions, attitudes, and actions?...

More at https://www.philosophytalk.org/shows/are-we-alone. News that life might exist or have existed on Mars or somewhere else in our universe excites many. But should we really be happy to hear that news? What are the philosophical implications of the possibility of extraterrestrial life? If life can blossom in our own cosmic backyard, then that means that the universe is most likely saturated w...

More at https://www.philosophytalk.org/shows/trolling-bullying-and-flame-wars. Open up any online comments section and you’ll find them: internet trolls, from the mildly inflammatory to the viciously bullying. It seems that the ease of posting online leads many to abandon any semblance of intellectual humility. So can we have intellectual humility on an anonymous forum with little oversight and ac...

More at https://www.philosophytalk.org/shows/how-humbly-disagree. People like to argue, especially Philosophy Talk listeners! But no matter how hard we try to resolve disputes through rational discourse, sometimes we may still disagree about important issues. One response to this predicament is simply to agree to disagree. But should the mere fact of disagreement lower our confidence in our views?...

More at https://www.philosophytalk.org/shows/could-laws-physics-change. From airplanes flying overhead to the cellular activity inside us, all events that take place in the world obey the laws of physics. Physicists seem to be getting closer and closer to understanding the physical laws that govern our universe. But what if our physical laws changed? Could that even be possible? How might changing...

More at https://www.philosophytalk.org/shows/driverless-cars-moral-crossroads. Autonomous vehicles are quickly emerging as the next innovation that will change society in radical ways. Champions of this new technology say that driverless cars, which are programed to obey the law and avoid collisions, will be safer than human controlled vehicles. But how do we program these vehicles to act ethicall...

More at https://www.philosophytalk.org/shows/cognitive-bias. Aristotle thought that rationality was the faculty that distinguished humans from other animals. However, psychological research shows that our judgments are plagued by systematic, irrational, unconscious errors known as ‘cognitive biases.’ In light of this research, can we really be confident in the superiority of human rationality? How...

More at https://philosophytalk.org/shows/knowing-what-we-know. It seems like we know many facts about ourselves and the world around us, even if there vastly many others we know that we don’t know. But how do we know if what we believe to be true is really knowledge? Can our beliefs be both justified and true, yet still not count as genuine knowledge? If so, then how much confidence should we real...

More at https://philosophytalk.org/shows/space-time-continuum. Strange things are said about time: that it's illusory, that it has no direction. But what about space, or the space-time continuum? What exactly is space-time? Are space and time fundamental features of the world? How do Einstein’s special and general theories of relativity change our understanding of space-time? Is there a distinctio...

More at http://philosophytalk.org/shows/mystery-multiverse. At the foundation of modern theoretical physics lie the equations that define our universe, telling us of its beginnings, evolution, and future. Make even minor adjustments to the fundamental laws of the universe, and life as we know it would not exist. How do we explain this extraordinary fact that our universe is so uniquely fine-tuned...

More at http://philosophytalk.org/shows/dark-matter. All the matter we have ever observed accounts for less than 5% of the universe. The rest? Dark energy and dark matter: mysterious entities that we only know about from their interactions with other matter. We infer their existence to satisfy our laws—but are we justified in making conclusions about what we cannot directly measure? How far can we...

More at http://philosophytalk.org/shows/big-bang-before-and-after. The Big Bang theory is the prevailing theory about the “birth” of the universe. It posits a singularity, or super high density state from which the entire universe expanded and continues to expand. But what exactly is the Big Bang, and what’s the evidence that it took place? How do we account for the “Big Bang state”? Was there som...

More at http://philosophytalk.org/shows/why-something. 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 b...
