Postdoctoral fellow, University of Johannesburg

Ragnar is a post-doctoral research fellow at The University of Johannesburg. His research interests are in the philosophy of science, philosophy of truth, pragmatism, and complexity science. Ragnar’s PhD thesis focused on questions related to how we can have knowledge of the world given its complex nature and, most importantly, what this can tell us about scientific progress and scientific truth. Some of the journals where Ragnar has published include Axoimathes, Foundations of Science, and Journal for General Philosophy of Science. He has given talks at seminars hosted by, among others, Bath University, Kent University, University of Connecticut, and University of Vienna.
