Aristotle has been often credited (and sometimes blamed) for single-handedly changing the way we think about philosophy and the world. The scope of his work spans the entire range of the humanities and sciences: biology, physics, cosmology, logic, language, poetry, ethics, politics and metaphysics. This course will aim at understanding the theoretical side of Aristotle's thought by focusing on his contributions to science, epistemology, and metaphysics. Some of the core questions in this area include: To what extent is Aristotle's thought compatible with Plato's? What is "first philosophy" and where is it to be found? Why does Aristotle deny the unity of natural sciences (or doesn't he?) In addition, particular attention will be paid throughout the course to Aristotle's notions of nature, soul, and God. All reading will be in translation, and no knowledge of Greek is necessary. Reading assignments will consist of both primary and secondary texts. Format: seminar. Requirements: two 8- to 10-page papers and regular short, informal class presentations. Prerequisites: Philosophy 102 or permission of instructor. Enrollment limit: 19 (expected: 5-15).
