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, co-author of "The Many Faces of Impossibility."

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, author of the Oxford Bibliography on Mary Astell.

More at 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."

More at https://www.philosophytalk.org/shows/hildegard-of-bingen. Hildegard von Bingen was a 12th century mystic, polymath, and composer whose work spanned visionary theology, philosophy, cosmology, medicine, botany, and music. Her extraordinary intellectual accomplishments belie her humble claim to be “just a woman”. Was her humility justified in the face of the divine, internalizing misogynistic stereotypes, or a strategic decision to get her voice heard? What can mystical experience teach us about the world? And how can we understand ourselves in relation to the divine? Josh and Ray explore her life and thought with Jennifer Bain from Dalhousie University, editor of "The Cambridge Companion to Hildegard of Bingen."

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 https://www.philosophytalk.org/shows/philippa-foot. Philippa Foot invented the thought experiment that famously became known as the Trolley Problem. Despite the vast industry of “trolleyology” it inspired, Foot’s goal to illuminate debates on abortion and euthanasia often gets lost in the mix. So, how did Foot use this thought experiment to distinguish between doing versus allowing? What did she mean by the "Doctrine of Double Effect"? Why did she think that cultivating classic virtues—justice, courage, prudence, and temperance—was in our own rational self-interest? And what made her later change her mind? Josh and Ray explore her life and thought with John Hacker-Wright from the University of Guelph, author of "Philippa Foot's Moral Thought."

More at https://www.philosophytalk.org/shows/mary-midgley. 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." Part of our Wise Women series, generously supported by a grant from the National Endowment for the Humanities.

More at https://www.philosophytalk.org/shows/iris-murdoch. 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." Part of the "Wise Women" series, generously supported by a grant from the National Endowment for the Humanities.

More at https://www.philosophytalk.org/shows/judith-jarvis-thomson. 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). Part of the "Wise Women" series, generously supported by a grant from the National Endowment for the Humanities.

She also famously protested Truman’s decision to drop the atomic bomb when he was awarded an honorary degree at Oxford. Josh and Ray explore her life and thought with Rachael Wiseman from the University of Liverpool, co-author of "Metaphysical Animals: How Four Women Brought Philosophy Back to Life."

More at https://www.philosophytalk.org/shows/crisis-and-creativity-mayan-mythology. The Popol Vuh, written in 1702, was based on a Mayan oral tradition encompassing creation myths, history, and cosmology. These stories were written in a time of crisis: European colonialism had decimated the Mayan population and destroyed much of their cultural knowledge. How do stories help a society survive and thrive? Can they console us in times of crisis? How much of a culture can historians save in times of devastation? Josh and Ray rewrite history with Edgar Garcia from the University of Chicago, author of "Emergency: Reading the Popol Vuh in a Time of Crisis."

More at https://www.philosophytalk.org/shows/emma-goldman. Activist and anarchist philosopher Emma Goldman fought for human liberation in every realm of life. While she opposed the women's suffrage movement, she was a staunch advocate for women’s rights. So why did she think the right to vote was so unimportant? What did she think was required to achieve her anarchist goals? And how ahead of her time was she on labor, prison abolition, and sexual liberation? Josh and Ray explore her life and thought with Candace Falk from UC Berkeley, editor of "Emma Goldman: A Documentary History of the American Years."

More at https://www.philosophytalk.org/shows/american-futures. When Ken Taylor passed away suddenly 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 2023 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/simone-weil. French philosopher and mystic Simone Weil was also an activist whose goal was to elevate the lower classes. But she was opposed to the kind of revolution where the oppressed overthrow their oppressors. So, how did she think we could achieve peace and justice? Is it enough to pay the right kind of attention to each other's suffering? And how does this connect to her conversion to a mystical form of Christianity? Josh and Ray attend to the life and thought with Rebecca Rozelle-Stone from the University of North Dakota, author of "Simone Weil: A Very Short Introduction."

Born into slavery in the nineteenth century, Anna Julia Cooper received a classical education, attended the Sorbonne, and became the fourth African American in history to be awarded a PhD. Her first book, A Voice from the South, offered one of the first articulations of how Black women are impacted by race, gender, and socioeconomic class. She believed that uplifting Black women through higher education would improve life for all Black people. Josh and Ray explore her life and thought with Kathryn Sophia Belle, author of "Beauvoir and Belle: A Black Feminist Critique of The Second Sex."

More at https://www.philosophytalk.org/shows/nisia-floresta. Nísia Floresta was a 19th-century writer and translator known as “the Brazilian Mary Wollstonecraft.” She published the first book on women’s rights in South America, when Brazil was gaining independence from Portugal and a new post-colonial nation was being built. She also argued for the rights of the enslaved and indigenous Brazilians, who were marginalized and exploited in this new nation. Josh and Ray explore her life and thought with Nastassja Pugliese from the Federal University of Rio de Janeiro, author of "Nísia Floresta (Elements on Women in the History of Philosophy)."

More at https://www.philosophytalk.org/shows/mary-wollstonecraft. Mary Wollstonecraft is often labeled as a “liberal feminist” because of her concern for women’s rights and conceptions of freedom. But that label narrows her work, which was broadly critical of all social inequalities that distort human relations. So why did Wollstonecraft think that virtue is not truly possible unless we are all free? What did she think was key to the liberation of women? And what were her criticisms of the powerful institutions of her day, like the monarchy? Josh and Ray explore the life and thought of Mary Wollstonecraft with Sylvana Tomaselli from the University of Cambridge, author of "Wollstonecraft: Philosophy, Passion, and Politics."

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, and author of "The Artificial Intelligence of the Ethics of Artificial Intelligence: An Introductory Overview for Law and Regulation."

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 in Hartford, author of "Shakespeare's White Others."
