The title of today’s episode is “Rules.” The term “rules” encompasses a variety of concepts, including algorithms, maxims, principles, models, laws, regulations, and even laws of nature. In essence, rules shape our world and our lives. My guest for this conversation is Prof. Lorraine Daston. Lorraine Daston is Director Emerita at the Max Planck Institute for the History of Science in Berlin, a Permanent Fellow of the Wissenschaftskolleg zu Berlin, and a Visiting Professor in the Committee on Social Thought at the University of Chicago. After studying at Harvard and Cambridge Universities, she taught at Princeton, Harvard, Brandeis, Chicago, and Göttingen Universities before becoming one of the founding directors of the Max Planck Institute for the History of Science in Berlin, serving from 1995 until her retirement in 2019. She has published extensively on topics in the history of science, including probability, wonders, objectivity, and observation. She is a member of the American Academy of Arts and Sciences, the American Philosophical Society, the Leopoldina National Academy of Germany, and a corresponding member of the British Academy. One of her recent books, titled Rules — the namesake of this episode — will be at the center of our discussion. For our German audience, a German translation of this book is also available.  This episode has another inspiring connection: in Episode 120, I spoke with her husband, Prof. Gerd Gigerenzer. If you are German-speaking, I highly recommend listening to both episodes, as you’ll find a number of overlapping and complementary topics and ideas.
