Philosophy is often described as "thinking about thinking;" variously conceived inquiries into the nature, limits, and canons of human reasoning have always been at its heart. Without challenging the centrality of such projects for philosophy, this course will focus on a less emphasized, but equally essential aspect of our lives: emotions. What are emotions, and how should we think about them? What is the proper "geography"-classification and analysis-of our emotions and what is their relation to our beliefs, judgments, and evaluations? Which methodological approach-if a single one can be thus privileged-should we adopt for examining emotions? Finally, what is the scope and nature of an adequate theory of emotions, what are the desiderata for such a theory, and what should count as evidence in its favor? We will examine a variety of philosophical and scientific (psychological and biological) theories of emotion, as well as some, more recent, theories developed within history, sociology and anthropology. Format: seminar. Requirements: weekly short response papers (1-2 pages), oral presentation, class participation, and a 10- to 15-page final paper. The class is required of all senior philosophy majors and open only to them.
