Karl Popper famously claimed that what separated science from pseudoscience was that scientific theories were falsifiable. This claim about the importance of scientific predictions and the testability of theories is still commonly accepted by scientists and non-scientists alike and was, for example, very important in American court cases involving the teaching of Evolution, Scientific Creationism, and Intelligent Design in schools. But there are well-known are arguably insuperable problems with Popper's account. This talk given by Dr. Joel Velasco, Assistant Professor of Philosophy at Texas Tech University, will examine some of these problems and ask how we should think about the nature of scientific theorizing in light of them.
