This course is an overview of contemporary issues in the philosophy of science. Questions we shall address include the following: What distinguishes science from pseudo-science? Can there be crucial experiments? What is the nature of scientific change? Are scientific theories converging on the truth? Is science objective? How do we know things we cannot observe directly, such as electrons, really exist in the way our theories say they do? What is an adequate scientific explanation? Could all of science in principle be explained by physics? The texts for the course are Thomas Kuhn's The Structure of Scientific Evolutions and Curd and Cover's anthology, Philosophy of Science: The Central Issues.
