Gregory B. Sadler

I bring philosophy into practice, making complex classic philosophical ideas accessible for a wide audience of professionals, students, and life-long learners.

After a decade in traditional academic positions, I started my own business and began doing philosophical work in more practical contexts. I am an APPA-certified philosophical counselor, a public speaker, an author, an ethics trainer, and an executive coach (among other things!). I am also the editor of Stoicism Today and the producer of the Half Hour Hegel series.

Partially Examined Life

Philosophy, philosophers and philosophical texts. The format is an informal roundtable discussion, with each episode loosely focused on a short reading that introduces at least one “big” philosophical question, concern, or idea.

The Partially Examined Life podcast is our attempt to recreate the good old days when we’d meet up after a seminar to drink beer and talk shop or get some teaching yas out where students couldn’t talk back. We’re recording it to share our joy in “doing” philosophy with all who care to listen (and occasionally ranting bitterly about the profession that we so long ago escaped).
