“The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato.”

  • The Meaning of ‘Literal’: Thinking with Owen Barfield and Alfred North Whitehead

    The following essay is adapted from the transcript of this recording on our Urphänomen research guild Substack. It is a poetic commentary on Owen Barfield’s essay in The Rediscovery of Meaning, “The Meaning of ‘Literal,’” which was also the subject of discussion in this morning’s reading group: When Whitehead remarked that every science has its…

  • Metaphysics and Theology (a dialogue with Jacob Sherman)

    This dialogue with my colleague Jake Sherman was recorded last week at our graduate program’s annual retreat.  Below is a transcript:  Matt: Welcome, everyone. Thanks for joining us this afternoon for a dialogue on metaphysics and theology, which I hope will be both interesting and entertaining. You should have found the score cards on your seat to decide…

  • The Cosmic Poetry of Whitehead’s Philosophy: Notes on my dialogue with Ingrid Rieser

    You can listen to my conversation with Ingrid over on her Forest of Thought podcast, or read the revised transcript of my remarks below. We recorded this in Claremont, CA back in June at the “Is It Too Late?” conference on ecological civilization (you can watch my conference presentation on Whitehead’s advice for the business mind here).  “Philosopher” is…

  • From Substance to Creativity, Or on the Modernity That Could Have Been

    Yesterday in my history of Western philosophy course, where my students are reading Richard Tarnas’ Passion of the Western Mind (1991), I lectured on a couple of seventeenth century philosophers in an attempt to catch the nature of the shift that historians call “the Enlightenment.” I then connect their innovations to a couple of nineteenth and twentieth…

  • Between the Speculative and the Prosaic: Life, Imagination, and Individuation

    Timothy Jackson and I went deep into descendental philosophy and aesthetic ontology, core concepts developed in my last book Crossing the Threshold (2023). I try to argue against both scientistic neutrality and dogmatic theology. I believe that any attempt at thinking the most general conditions of reality inevitably touches the spiritual. If it did not then natural science…

  • The Return of Form in Biology: Thinking Through Platonic Morphospace

    The mystery of biological form has led some biologists, most prominently Michael Levin, back to Plato’s theory of Ideas. Levin is driven primarily by the surprising empirical findings of his lab. He argues that his results are best explained by reference to modes of causality not traceable to genetic histories or molecular components. While he has…

  • Jung, Simondon, and the Ontogenesis of Philosophy

    We just wrapped the “Forever Jung” conference co-hosted by CIIS and the San Francisco Jung Institute. Tim couldn’t be with us in person, but I enjoyed his Zoom presentation on Jung and Simondon (video of his talk should be online soon; you can listen to mine here).  Below are some LLM assisted notes on Tim’s exegesis of the…

  • Remembering the Repressed with Carl Jung and Rudolf Steiner

    Judi: Hello, everybody. It’s my great pleasure to introduce Matt Segall. Matt is a PhD, a transdisciplinary researcher, philosopher, and teacher applying process-relational thought across the natural and social sciences.

  • Beyond MAGA and Wokeshevik Ressentiment: Or how to avoid a civil war

    Charlie Kirk’s assassination is a national tragedy, an unmistakable symptom of civic decay. Kirk’s murder deserves clear condemnation. But condemnation need not include canonization. Kirk’s shock-jock rhetoric served only to divide people and does not suddenly become virtuous because he was killed by an unhinged ideologue. Those of us trying to reverse the decay of…

  • Matter, Life, and Mind: Love as a Cosmological Power

    This was recorded on Saturday, September 13, 2025 as part of the Frontiers of Knowledge event at Wheeler Opera House in Aspen, CO. Below is the recording and a lightly edited transcript.  Good morning, everyone. I want to begin by thanking you all for allowing your curiosity to draw you here. We are engaged in a…

  • Birthing a New Cosmology (reflections on my dialogue with Alexander Beiner)

    I enjoyed dialoguing with my friend Alexander Beiner this morning. The recording will be published on Kainos soon. He asked whether I had a sense for whether the atheistic, secular orientation in academia is thawing, opening room for alternatives to physicalism. I do sense that! Panpsychism and idealism are the two broad categories that capture much of…

  • Value at the Root: Cultivating Virtue in a Post-Truth World

    Context  The following reflections grow out of my live dialogue with Bonnitta Roy about the metaphysics of value. She’ll be sharing the discussion in her pop-up school for those who subscribe. Here I wanted to offer some further reflections on what was stirred up in me. A few orienting points: First, we wanted our philosophical conversation to…

  • Facing the Face Within: Christopoetics in an Unfinished World in Process

    Below is a draft of a chapter for a book on radical and process theologies. My contribution is based on a conversation I had with Peter Rollins earlier this year: Facing the Face Within: Christopoetics in an Unfinished World in Process By Matthew David Segall Ahead of turning to the body of this exposition, a…

  • Notes from the Edge of the Ordinary

    Recapping my time in the twilight zone between physics and psi in Charlottesville, Virginia two weeks ago. I left the DOPS Psi Theory Meeting feeling like I’d been sitting around a camp fire telling ghost stories at the edge of a new continent. In fact, we spent the week together in the Marriott Hotel’s appropriately named Louis…

  • Cosmology, Democracy, and the Spirit of the Earth: Talking Process-Relational Political Theology with Tripp Fuller and Aaron Simmons

    I joined Tripp and Aaron to discuss the changing role of religion in public life in our tumultuous political moment. We were discussing my lecture offering a Whiteheadian process cosmological response to Carl Schmitt’s critique of liberalism. “Between Earth and Empire: Cosmopolitical Democracy Beyond the Liberal Horizon“ When Tripp asked how a process philosopher might…

  • Creativity and the Cross: Martinus, Bergson, and Whitehead in Dialogue

    A conversation with Pedro Brea and Karsten Jensen. LLM generated transcript below. Matt Segall: Hey, Karsten. Pedro Brea: Hey! Karsten Jensen: Hi, Matt! Hi, Pedro! I’m so happy you both agreed to have this conversation with me, and I really look forward to it. Matt Segall: Likewise. My exposure to Martinus was through you, Karsten, and I really appreciated…

  • Sancta Maria Magdalena

    Last Tuesday, on Mary Magdalene’s Feast Day, I walked as a pilgrim with about a dozen others from Lewes train station to St. Peter’s Church in Firle along part of a historic route called the Old Way in the south of England that stretches from Winchester in Hampshire to Canterbury in Kent. I slept in…
