About The Course

This is a 16-week online course, focused on selected philosophy and literature from key authors in the Existentialist movement. Existentialism encompasses a broad and diverse set of thinkers in the 19th and 20th century, who are often in productive disagreement with each other, but who grapple with central and common questions of human existence.

We will be studying and discussing key themes, images, arguments, distinctions, insights, and characters found in representative works by Kierkegaard, Dostoevsky, Nietzsche, Shestov, Rilke, Unamuno, Kafka, Heidegger, Marcel, Sartre, De Beauvoir, Camus, Fanon, and Nishitani


The class will meet online for weekly 90-minute class sessions using Zoom, on Thursdays at 9 AM Central Time. All class sessions will be recorded and students can watch them at their leisure as often as they like. Students will also be provided with handouts developed by the instructor, some of which will be brand new for this course!

This is an open-access version of a class Dr. Sadler developed and taught in academic institutions numerous times over the last two decades.

About The Instructor

After a successful career as a college professor, researcher, and administrator, I started our company, ReasonIO to help people study and apply philosophy in public, practical, and professional contexts. I continue teaching philosophy, literature, religious studies, and humanities courses at the Milwaukee Institute of Art and Design.

I take difficult philosophical texts, thinkers, and topics, and make them accessible for everyday people. That's how philosophy gets traction and remains closely connected with real life!

From 2016 to 2022, I served as the Editor of Stoicism Today. I remain a member of the Modern Stoicism, ltd. team. I am also the producer of the Half Hour Hegel series. I have authored one book (Reason Fulfilled By Revelation), edited two volumes (Stoicism Today Selected Essaysvolume 3 and volume 4), and published dozens of articles, book chapters, and encyclopedia entries. Although I work in significant part outside of the academy, I remain actively engaged in research and scholarship.

I have held a Research Residency at the Institute for Saint Anselm Studies, been a Visiting Scholar position at European Graduate School, and was a Charles Chesnutt Library Fellow. I am also an APPA-certified Philosophical Counselor.
