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."

Mary Midgley became one of the best known public intellectuals in the UK, and was one of the first philosophers to talk about climate change. Though she didn’t publish her first book—Beast and Man—till she was 59, she wrote many influential works on science, ethics, and animal rights. So, why did Midgley argue that the climate crisis was ultimately a conceptual problem? What was her criticism of scientism, the view that only science can provide knowledge about the world around us? And why did she think the work of the philosopher is a bit like that of the plumber? Josh and Ray explore her life and thought with Clare Mac Cumhaill from Durham University, co-author of "Metaphysical Animals: How Four Women Brought Philosophy Back to Life."

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."

Rules exist for a reason: they tell us what to expect, they help us coordinate our actions, and they stop us from exploiting one another. But isn't it possible to be too much of a rule follower? Aren't some rules arbitrary, unjust, or just plain inefficient? When should we exercise our judgment to reinterpret the rules, and when should we ignore them altogether? Josh and Ray break all rules with Barry Lam from UC Riverside, author of "Fewer Rules, Better People The Case for Discretion."

Iris Murdoch may be best known for her works of fiction, but her philosophical contributions were equally significant. A moral realist influenced by Plato and Simone Weil, she developed theories in virtue ethics and care ethics. So what is the relationship between Murdoch's works of fiction and her philosophical writings? Why did she believe that "nothing in life is of any value except the attempt to be virtuous"? And given that, why did she think human life has no purpose? Josh and Ray explore Murdoch's life and thought with Eva-Maria Düringer from the University of Tübingen, author of "Evaluating Emotions."

There is consensus among scientists that global warming is real and that it’s caused by human activity. Despite the overwhelming evidence and the urgency to act, there are still many who are skeptical of or flat-out deny climate change. Are these climate deniers simply impervious to scientific evidence? Or have they just not been exposed to the right kind of information? When it comes to ideologically driven views, is it possible to change people’s minds by appeal to facts? Or are humans hopelessly and incorrigibly irrational? The Philosophers don't deny talking to cognitive scientist Michael Ranney, head of the Reasoning Research Group at UC Berkeley.

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.

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."

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."

Judith Jarvis Thomson is best known for arguing that abortion is morally permissible, even granting the fetus the status of person. Her colorful thought experiments illustrate that a right to life does not mean the right to use another person's body to survive. So, what exactly is a right to life and what does it permit or prohibit? Does pregnancy come with certain moral obligations to the fetus? And how can thought experiments, like the Trolley Problem, shed light on these questions? Josh and Ray explore Thomson's life and thought with Elizabeth Harman from Princeton University, author of "When to Be a Hero" (forthcoming).
