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…

Schelling’s Reading of Plato’s “Timaeus”
In this dialogue, Tim Jackson and I return almost to the beginning of philosophy–“almost” in the sense that Plato himself was already responding to a few centuries of philosophizing by the physiologoi. His dialogue Timaeus represents a synthesis rather than a pure start in the evolution of philosophy. He attempted to reconcile different positions and…

Discussing “The Blind Spot” with Gregg Henriques
Here is a rough transcript of some of my comments to Gregg: I think this book speaks to both of us for obvious reasons. The work you’ve been engaged in with your UTOK system to bring together the humanities and the natural sciences in a more comprehensive, systematic perspective, and any of the dialogues you’ve…

Paradigm Shifts, Human Experience, Panpsychism, and Psychedelics (dialoguing with Jack Roycroft-Sherry)
Jack and I discussed a number of topics, beginning with how science and philosophy might be demarcated. I suggest that science, born from natural philosophy, relies on metaphysical presuppositions and requires philosophical foundations to justify its knowledge claims. Philosophy seeks the general and universal, while science specializes in isolated regions of inquiry. Both are valuable…

Processing Process Ontology (dialogue with Bonnitta Roy and Gregg Henriques)
Bonnie, Gregg, and I met to discuss the interplay between process philosophy and UTOK. We begin by unpacking the status of metaphysics vis à vis science in order to head off some common misconceptions. I make the point that physics has been without a widely accepted metaphysical underpinning since the quantum and relativistic revolutions of the early 20th century. Physics…

Debating the Place of the Human in Cosmology with Brendan Graham Dempsey
After some back and forth in his Facebook group, Brendan was gracious enough to invite me on his Metamodernism podcast to discuss several core ideas, including the nature of scientific inquiry, the role of human experience in understanding the cosmos, and the limitations of mechanistic models in science. We discussed the intersection of philosophy, science,…

Cosmic History in Steiner and Whitehead (dialogue with Formscapes)
This was a really fun conversation with Formscapes (check out his content on YouTube). The dialogue begins with Whitehead’s ideas on hybrid prehension and how they might relate to Steiner’s cultivation of higher organs of spiritual perception. Whitehead appears to have been open to esoteric ideas, based on some evidence that he tried contacting his…

Are there alternatives to the Big Bang?
In November, Tim Eastman and I were invited by the Cobb Institute to reflect on the status of the cosmological theory popularly known as the “Big Bang,” a.k.a. the ΛCDM (Lambda cold dark matter) or Lambda-CDM model. Earlier this year, NASA’s new James Webb Space Telescope came on line. Its huge mirrors allow for a six fold…
