An Invitation To The Class


About The Course

This is a 8-week online course, centered on studying one of the most important works in virtue ethics in the 20th century, After Virtue by Alasdair MacIntyre.

We will be studying and discussing key themes, images, arguments, distinctions, insights, and narratives within this work, going through the entire book chapter by chapter. We'll also look at several other short pieces by MacIntyre as well as by selected critics of his work.

The class will meet online for weekly 90-minute class sessions using Zoom, on Saturdays 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!

Gregory Sadler Teaching In Front Of Chalkboard

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.

Scott Tarulli, professor, Berkelee School of Music

"Philosophy classics always intimidated me. I couldn't follow a lot of it, and I did not get much out of reading. When I went to study with Dr. Greg Sadler, he helped me read the works in pieces while helping me understand. The best part is, he encouraged me to think about how some of these ancient ideas could be applied into my own life. I found him very personable, and kind. Absolutely fantastic mentor!"

Shirley Sciacca, student and working professional

"Dr. Sadler’s remarkable passion for philosophy, teaching, discussing, and engaging with others creates enlightenment across all fields of study. His energy is contagious as we delve into readings from Nietzsche, Kant, Plato, Aristotle, or Cicero.   Philosophy complements the very essence of who we are and I can’t wait to join Dr. Sadler (and his wonderful sense of humor) alongside my fellow students again as I give honor to the life-long learner in me."

Marc Smit, founder, Philosophy Companion

"Studying philosophy is rewarding but can also be challenging and lonely. Dr Sadler makes classical and modern texts approachable and accessible, while his classes bring me into conversation with fellow learners. His teaching has not only given me intellectual understanding but also a better appreciation for how I can put philosophy into practice."
