Philosophy Talk

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. Part of our series Wise Women, supported by a grant from the National Endowment for the Humanities.

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

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?

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.

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.

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.

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 present selves welcome back Parfit’s former student David Edmonds, author of Parfit: A Philosopher and His Mission to Save Morality.

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.

What movies of the past year challenged your assumptions and made you think about things in new ways?
