The course has two goals. First, to give you a sense of what philosophers think about and why. Here we look at a number of perennial philosophical problems, including some or all of: how knowledge differs from "mere opinion," the objectivity (or not) of moral judgment, logical paradoxes, mind/body relations, the nature and possibility of free will, and how a person remains the same over time, as their bodily and psychological traits change. The second goal is to get you thinking philosophically yourself. This will help you develop your critical and argumentative skills more generally. Readings will be from late, great classical authors and influential contemporary figures.
