Ceteris Never Paribus takes its name from a twist on a familiar phrase, and its tagline spells the twist out: all other things are never equal. That idea runs through the episodes. Economic ideas come across as the products of argument and struggle, not settled truths. Two of the interviews here each center on one piece of research, a book in one case and a doctoral thesis in the other. In one, Fredrik Albritton Jonsson, an associate professor of British history at the University of Chicago, and Carl Wennerlind, a professor of history at Barnard College, discuss their book 'Scarcity: A History from the Origins of Capitalism to the Climate Crisis'. Their argument is that today's dominant view, endless desires demanding endless growth, emerged only over centuries of debate. Bernard Mandeville appears along the way, treating ever-growing consumption as natural to humanity. So does the South Sea bubble, after which that dream of infinite expansion was ridiculed. In the other interview, Maria Back talks with Dr. Saarang Narayan, a historian of twentieth-century South Asia whom she met at the Indian Conference for History of Economic Thought in New Delhi. His subject is the Swadeshi movement. The conversation reaches a rare fault line: the 1990s tension within Hindu nationalist networks between Swadeshi and pro-globalization positions. The show's blog adds a list of key terms with short explanations, a small help for listeners new to the subject. The show's range also goes beyond the history of ideas into the working life of research. Its series on supervision asks what makes a good doctoral supervisor, and the answers come from both sides of the desk. One supervisor describes students who simply disappear, and how hard it is to rebuild trust once it breaks. A student named Adele recalls leaving a meeting ready to drop one thread of her research for a second one that felt simpler. The episode billed as a conversation with Peter Boettke, a sort of PhD coach, covers peer-to-peer workshops where graduate students present proposals and chapters, with the emphasis on constant engagement over any cookie-cutter method. The series closes by boiling its conversations down into ten commandments for supervisors and students, starting with a practical one: use a reference manager. Its presenter also thanks their own supervisor for one lasting image, the reminder to see the forest and not only the trees. A recurring introduction quotes John Maynard Keynes on the foolish things a man thinking alone can come to believe, answers that no one here has to think alone, and includes audio of Paul Krugman's 2008 Nobel Prize banquet speech. What a listener gets is two things at once: the history of economic ideas, and a candid look at how the people who study them are trained.
