Final Call for Papers Synthese Topical Collection on Simplicity out of Complexity? Physics and the Aims of Science *Deadline: 31 July 2020* Guest Editors Florian J. Boge (University of Wuppertal) Paul Grünke (Karlsruhe Institute of Technology) Martin King (University of Bonn) Miguel Ángel Carretero Sahuquillo (University of Wuppertal) * Description The world we live in is notoriously complex: there is an outright zoo of material particles, a vast variety of different species, a whole plethora of stars and galaxies, and so forth. Yet many scientific achievements, such as the Standard Model of particle physics or Darwin’s theory of natural selection, allow us to manage part of this complexity by means of a simple set of laws or general rules. Simplicityhas often been assumed to be an epistemic ideal, most clearly exemplified in physics, with its trend towards encompassing theories that feature only a small number of fundamental laws, capable of explaining a large number of diverse phenomena. This view of science, with physics at the center stage, has arguably provided the dominant narrative in mainstream philosophy of science throughout the 20thcentury. Yet many questions arise when one zooms in on the details. For instance: in what sense can the laws of physics be said to be simple, when concrete computations based on them are tedious or even impossible? How do notions of simplicity differ across the sciences, and what are their commonalities? Does the striving for simplification of perceived complexity imply an unjustifiedreductionism? Is simplicity really an epistemic ideal or just endorsed for pragmatic reasons, and maybe even an unreliable guide to truth? If so, what should it be replaced with? The aim of this Topical Collection is to bring together contributions from different fields, such as (the philosophy of) physics, biology, economy, psychology, linguistics, or general philosophy of science. Topics may include but are not limited to: • epistemic vs. practical: Is simplicity an epistemic goal of science or just a practical benefit? (Why) should theories aim for simplicity, or (why) not? • physics vs. other sciences: Does the complexity of the world largely preclude simple science? Is complexity also an aim of the special sciences? Does contemporary physics really aim at simplicity? • the concept of simplicity in science: What does it mean to be a ‘simple’ theory? What is simplicity? Can there be a unified account of simplicity or should one embrace pluralism? We invite contributions from the full spectrum of disciplines and their respective philosophies, scientists and scholars reflecting on their respective and neighboring research fields, as well as historians, philosophers and sociologists of science investigating the epistemologies, practices, and discourses of fellow epistemic communities. * For further information, please contact the guest editors: o Florian J.
