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).

  • Episode 213: Nietzsche's Zarathustra (Part One)
    On Friedrich Nietzsche’s Thus Spoke Zarathustra, books 1 and 2 (1883). What is wisdom? In this text whose style parodies the Bible, we get pithy advice and allegorical imagery to guide us away from self-defeating, life-denying attitudes and orient us towards creative self-overcoming (i.e. exertion of the Will to Power).…
  • Episode 212: Sartre on Literature (Part Two)
    Continuing on What is Literature? (1948). Sartre gives a phenomenology of reading and writing that makes reading into a creative act of completing the writer's work, and calls this cooperation ethical: the work is an appeal to the reader's freedom, and also the reader's responsibility to then know what the…
  • Episode 212: Sartre on Literature (Part One)
    On Jean-Paul Sartre's What is Literature (1948), ch. 1 and 2. What's the purpose of literature? Why write prose as opposed to poetry? Sartre argues that while poetry is about the words themselves, prose is about the ideas, so it's necessarily political. A written work is essentially an ethical appeal…
  • PREVIEW-(sub)Text#5: Chekhov's "Uncle Vanya"
    Wes Alwan is joined by Monica McCarthy of the Happier Hour podcast to discuss Anton Chekhov's 1898 play about family dysfunction and potentially wasting your life. This is a preview of a 54-minute discussion. You can listen to the whole thing by becoming a PEL Citizen or $5 Patreon supporter.…
  • Episode 211: Sartre on Racism and Authenticity (Part Three)
    Moving finally on to Jean-Paul Sartre's "Black Orpheus" (1948), where he introduces a book of black poetry by praising its revolutionary spirit as embodied in "negritude." Is this a legitimate consciousness-raising exercise or a weird fetishization of blackness? Listen to parts one and two first, or get the ad-free, unbroken…

  • E149 | The Cult of Mindfulness | Vishpani Blomfield, Linda Woodhead, Miguel Farias
    From yoga retreats to mindfulness, meditation is fashionable and now even prescribed by the UK's National Health Service. Yet in some cases it can lead to depression and even psychosis. Is it a mistake to think that self-exploration and being at one with ourselves are necessarily good things? Would it…
  • E148 | The Problem with Materialism | John Ellis, Susan Blackmore, Hilary Lawson
    The idea that the world is made of physical stuff alone has been central to scientific progress. But our theories do not account for experience or thought, and the particles of contemporary theoretical physics have no dimensions, so that material seemingly vanishes. Might materialism be a profound mistake? Should we…
  • E147 | Should we Live Forever? | Patricia MacCormack, Anders Sandberg, Janne Teller
    From gene therapy and fad diets to cryonically frozen corpses, many still hope to find a way to live forever. Some scientists are starting to think death might be reversible. But Heidegger famously thought life's transience gave it meaning. Does our fear of death prevent us from living fully? Can…

  • E145 | The Future of Pornography | Brooke Magnanti, Finn Mackay, Rowan Pelling, Peter Tatchell
    Many believe that porn's dark fantasies risk corrupting relationships and society. Has this arisen because pornography is largely created by men? Could feminist pornography featuring authentic sex, diverse bodies and female perspectives offer a truly liberating alternative? Or is porn fundamentally incompatible with intimacy and a problem for all of…
