  • Whitehead’s Philosophy of Science

    According to Susanne Langer, who was one of Whitehead’s students at Radcliff in the 1920s, every great philosophical scheme “must, in its original form, be regarded as a myth[1], which sets forth freshly and naively some new point of view [and] reveals new opportunities for rational construction” (The Practice of Philosophy, p. 178). Whitehead understood…


  • Reflections on the Whitehead Centennial at Emerson Hall

    My trip to Harvard gave me occasion to reflect not only on Whitehead’s legacy, but on his resonances with Emerson and their shared vision of philosophical education. It was raining Thursday afternoon when I arrived in Cambridge. My room at The Friendly Inn was a few blocks from Harvard Yard, and with the rain slowed…

Stengers focuses on how Whitehead’s ideas can help reconstitute a form of common sense in a world where…

You can listen to that conversation here: Deleuze, Whitehead, and the Computational Aesthetics of M. Beatrice Fazi About an hour and…


  • Notes on Carl Jung’s Problem of the Fourth (with help from Rudolf Steiner)

    In part five of his essay “A Psychological Approach to the Trinity,” titled “The Problem of the Fourth,” Carl Gustav Jung turns to Christian, Gnostic, and Hermetic religious symbolism for clues about the collective psychological development of Western humanity. His aim is not to offer metaphysical disambiguations of theological dogmas but to illuminate the path toward…

  • C. S. Peirce’s “A Neglected Argument for the Reality of God” (1908)

    In his 1908 essay, “A Neglected Argument for the Reality of God,” Charles Sanders Peirce offers a “humble hypothesis” meant to be accessible to the expert logician and clodhopper alike. God is identified as the ens necessarium, or the necessary being. This necessary being, according to Peirce, is the creator of all three (or at least…

    Ashton Arnoldy and Daniel Garner joined me to discuss the work of Owen Barfield. Here’s a quick summary of what we discussed: … I’ve been thinking with Barfield for many years!

  • C. S. Peirce’s Guess at the Riddle

    Later today, Timothy Jackson and I will meet to discuss Charles Sanders Peirce’s essay “A Guess at the Riddle” (1888; pages cited below from The Essential Peirce, Vol 1). I’ll update this post with the video once I’ve uploaded it. The essay lays out Peirce’s profound philosophical insight into the real idea of the triad, which he deploys (among…


  • Rudolf Steiner and the Dream of External Matter: Toward a Physiosophy of the Senses

    Over the weekend, I gave a talk at the Mysteries of Technology Conference: “Etheric Imagination as Participatory Knowing“ Unfortunately, I had to skip a few slides due to time constraints, so I wanted to share those ideas here. Below is something of an addendum to that talk, so a lot of what follows will make…

    An abridged transcript of my talk is below. For a more in depth look at social threefolding, you can also check out my article “The Urgency of Social Threefolding in a World Still At War With Itself” (2023).

  • Etheric Imagination as Participatory Knowing: A Process-Relational Reading of Rudolf Steiner’s “Light Course”

    Transcript:  It’s really lovely to be here this morning, though it’s quite early for me.

I think what MysTech is doing is important, not only for the wider world to see the ways in…


  • The Relevance of Whitehead’s Process Theology to Natural Science

    Below is a rough transcript of a Cobb Institute class lecture I gave earlier today. I’m going to speak a little bit about the relevance, as I see it, of process theology to natural science. Whitehead was kept in print, I would say, for the better part of the second half of the 20th century…

  • Becoming the World-Body

    You are not your brain, and you’re not just your body either, at least not if you think of your body as just what’s encased within the skin. To really understand what’s going on inside your body, you would need to understand its history, which is as old as the universe. Understanding the body means…


  • Re-Thinking Economics and the Meaning of Value with Tim Adalin and O. G. Rose

    It was a genuine joy to be in dialogue with Daniel and Tim yesterday. I want to reflect on some of what I shared during our discussion. The first thing I think, to frame my remarks, would be to say that over the last couple decades of my adult life, in thinking about economics and…
