n this seminar we will look at some of the central questions in the philosophy of science. We will examine debates about scientific realism and antirealism, the nature of scientific explanation, reductionism, and the (dis)unity of science. Questions that we will tackle include: What sets science apart from non-science? Should we be ontologically committed to the theoretical posits of our best sciences? How do scientific explanations work, and what tells the good from the bad ones? Are the special sciences reducible to more basic sciences? Is science unified or plural? We will read classic as well as recent work in philosophy of science to help shed light on these and related questions.
