Democratizing Science — Prof. Philip Kitcher

Who should decide which scientific questions deserve our attention? And can democratic deliberation help us make moral progress?This episode features Philip Kitcher, professor emeritus of philosophy at Columbia University and author of Science, Truth, and Democracy, The Ethical Project, and The Rich and the Poor.Kitcher argues that scientific research should reflect public needs rather than scientists' priorities alone. He explains how deliberation can resolve moral disagreements through mutual understanding, and why economic inequality undermines collective action on climate change. He also explores how literature and music can convey ethical insights more powerfully than philosophical arguments.Dialexicon is a free podcast dedicated to promoting philosophical education and deep reflection.

Why do we judge harmful actions differently from helpful ones? How much of our philosophical reasoning is shaped by moral intuition?This episode features Joshua Knobe, professor of philosophy, psychology, and linguistics at Yale University and a pioneer of experimental philosophy, which uses psychological experiments to investigate philosophical questions.Knobe explains how moral judgments shape our understanding of the "true self" and whether we consider actions intentional. He explores why people hold conflicting intuitions about free will, how our sense of normality influences judgments of causation, and why we hesitate to attribute consciousness to AI. He also discusses the growing intersection of philosophy and cognitive science.Dialexicon is a free podcast dedicated to promoting philosophical education and deep reflection.

What makes someone American? Can national identity unite people without excluding others?This episode features Rogers M. Smith, professor emeritus of political science at the University of Pennsylvania and author of Civic Ideals and Stories of Peoplehood.Smith argues that political communities depend on "stories of peoplehood" that inspire loyalty but inevitably privilege certain groups. From Thomas Paine to the Lincoln–Douglas debates, he traces America's enduring conflict between egalitarian ideals and exclusionary traditions. He also explains how national myths can inspire reform and why today's disputes over citizenship reflect centuries-old disagreements about American identity.Dialexicon is a free podcast dedicated to promoting philosophical education and deep reflection.

Who gets to belong to a political community? What makes a border legitimate? And if nations are human conceptions, could we build them differently?This episode features Joseph Carens, professor emeritus of political science at the University of Toronto and one of the most influential voices in the contemporary ethics of migration. He is the author of The Ethics of Immigration and of the landmark essay "Aliens and Citizens: The Case for Open Borders," which helped establish immigration as a central question in political philosophy.In this episode, Carens argues that nations are historical constructions rather than natural facts, and that anyone living as an ongoing member of a community deserves recognition as one. He makes the case that restrictions on movement function today much as they did under feudalism—sorting life chances by accident of birth—and explains why free movement is better understood as an indicator of a just world than a solution for an unjust one. He also discusses assimilation, citizenship tests, equal incomes in a market economy, and the open question of what AI will do to all of it.Dialexicon is a free podcast dedicated to promoting philosophical education and deep reflection.

What makes a society just? Why do vast global inequalities persist? And are wealthy countries merely failing to help the poor—or actively contributing to their poverty?This episode features Thomas Pogge, the Leitner Professor of Philosophy and International Affairs and Director of the Global Justice Program at Yale University. His work focuses on global justice, poverty, inequality, human rights, and the institutions that shape the global economy.In this episode, Pogge explores how philosophical ideas about justice translate into the institutions that shape everyday life. Moving from Rawls and Kant to poverty, political power, and climate change, he argues that injustice is often built into the rules themselves—not simply the result of individual choices. The episode ultimately asks what we owe others when the systems we benefit from may also be helping produce their disadvantage.Dialexicon is a free podcast dedicated to promoting philosophical education and deep reflection.

What exactly does it mean to think? Where are memories stored? And can studying the brain really tell us how the mind works?This episode features Caitlin Mace, a graduate student at the University of Pittsburgh whose research focuses on the philosophy of neuroscience. She previously earned her master’s degree in philosophy from California State University, Long Beach.In this episode, Mace explores the relationship between philosophy and neuroscience, asking what scientists can—and cannot—learn by breaking the brain into its component parts. She discusses reductionism, mental representation, optogenetics, and the challenge of determining where memories are physically stored. She also examines false memories, the surprising ways our recollections change over time, and whether memory might extend beyond the brain itself.Dialexicon is a free podcast dedicated to promoting philosophical education and deep reflection.
