PHIL 0990T: and Infinity Josh Schechter Thursday 4:00–6:20 PM Spring 2014 Course Information Instructor Joshua Schechter Office: Corliss-Bracket, 45 Prospect St, Room 307 Office Hours: Tuesdays 2-4 (and by appointment) Email: [email protected] Phone: 863-3225 (office)

Course Description This course will focus on several important that arise in and mathematics. We will use these paradoxes to investigate central issues in metaphysics, the philosophy of language, , physics, mathematics, and logic. Among the paradoxes we will discuss are the following: Zeno's paradoxes of space, time, and motion; the paradoxes of theory; the paradoxes of truth and reference; the ; paradoxes of rational action and rational belief. This course will primarily operate as a seminar. Given the technical nature of some of the material, however, I will lecture for some portion of each week.

There is no formal prerequisite for this course. It will not presuppose any particular background knowledge of philosophy or mathematics, but some background in either one would be helpful.

Course Requirements Students will be required to complete the following work: 1. One 15-20 minute in-class presentation sometime during the term on a paradox we are studying. 2. A 15-20 page paper due near the end of the term focusing on one of the paradoxes we have studied. 3. A 6-8 page progress report due near the middle of the term. This will provide a draft of a chunk of the student’s final paper. 4. Each week, students will be required to turn in written work. Most weeks, this will be a page or two that describes an issue in the reading for that week that they found particularly interesting or stimulating. For some weeks, I will assign set problems.
