Designed as an introduction to philosophical inquiry by way of conspiracy theories, "A Philosopher's Guide to Conspiracy Theories" will aim to equip students with the tools they need to seek out the truth in a "post-truth" world. The course will include a survey the basics of epistemology (the study of knowledge), philosophical argumentation, and good research practices. Over the course of the semester, we will address the following questions:  (How) do my beliefs affect others?  What is an echo chamber and how is it similar to the psychological practices of cult leaders?  What is required to thoroughly test and research a claim?  What is a conspiracy theory?  Is the world around me exactly as it appears?  What can I know about events for which I was not present?  How can I question the "official story" in a sophisticated, logically responsible way?
