This seminar enables students to undertake sustained philosophical research and write a graduate-level research paper. The first half of the course provides a detailed case study in the realism/antirealism debate. It examines the development of our philosophical and scientific understanding of space, time and motion from ancient times to the 19th century. These are among the most important theoretical entities in science. Are they real? The approach of the course is interdisciplinary, combining historical and philosophical perspectives with the scientists' own reflections. Many of the topics introduced in the first half remain active areas of philosophical research today. In the second half of the course students plan, develop and write a research paper, supported by in-class exploration of the relevant philosophical literature from the early 20th century to the present day. This is a 1.00 credit course.
