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.


Philosophy Talk

Philosophy Talk celebrates the value of the examined life. Each week, our philosophers invite you to join them in conversation on a wide variety of issues ranging from popular culture to our most deeply-held beliefs about science, morality, and the human condition. Philosophy Talk challenges listeners to identify and question their assumptions and to think about things in new ways. We are dedicated to reasoned conversation driven by human curiosity. Philosophy Talk is accessible, intellectually stimulating, and most of all, fun!

Philosophy Talk is produced by KALW on behalf of Stanford University, as part of its Humanities Outreach Initiative.

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).
