3 Philosophers Walk Into A Bar Fight: Understanding & Managing Anger Using Ideas From Philosophy

This is the recording from my invited talk on philosophical resources for understanding and managing anger, which was part of my alma mater Lakeland University's Thinkhaus talk series, given up at the Mead Public Library in Sheboygan, WI. The original recording from 2017 was made by a local high school AV club, which unfortunately didn't do a great job with sound, lighting, video, or editing, so I didn't release it at the time, but I've subsequently remastered it to improve all of those. In the talk, I discuss how ideas drawn from Plato, Aristotle, and Epictetus can help us to deal productively with the anger that we inevitably encounter or experience. Specifically, from Plato we learn how to identify the sorts of conflicts that are likely to lead to anger, from Aristotle how to assess our own anger responses, and from Epictetus how to shift our feeling of anger into a different feeling by reminding ourselves of why people do things that we take as wrong or offensive.
