Whitehead’s Quantum of Explanation: Thinking with Auxier and Herstein

“Our central idea is that concrete existence explains the abstract aspects of experience and not vice-versa.”
-Auxier and Herstein

“So long as necessity is taken to be the guarantor of rationality, the conception of rationality advocated will be as useless to science as it is to practical life.”
-Auxier and Herstein

Those looking for a proper review of their book should read George Lucas’ in NDPR. My thoughts are somewhat self-referential, as I am trying to sort through the intellectual earthquake unleashed within my mind as a result of reading this text.

Auxier and Herstein’s book has been on my radar for several years. I first read small sections of the unpublished manuscript in late 2016 as I was finishing my dissertation. The book was published last year by Routledge, unfortunately in highly abridged form. I just finished reading the published text in its entirety. It is nothing short of marvelous.  

Not since Isabelle Stengers’ Thinking With Whitehead: A Free and Wild Creation of Concepts (2011) has there been such a significant contribution to Whitehead studies. Some might question the extent to which Stengers’ book contributes to understanding Whitehead in his own terms. She often (I think fruitfully) reads Whitehead through a Deleuzean lens, and, more importantly for the authors of Quantum, she leans heavily on Lewis Ford’s “compositional analysis” of Whitehead’s philosophical genesis. Auxier and Herstein make many contributions to understanding Whitehead in their book, but one of the most forceful is their attempt to rebut Ford’s influential reading of Whitehead’s supposed “temporal atomism.” While Ford makes use of his theological training by applying methods of New Testament analysis to Whitehead’s texts, there discovering (or inventing?) evidence of radical breaks in his thinking during the 1920s, Auxier and Herstein argue rather convincingly for an unbroken continuity in Whitehead’s thought from his early work at Cambridge on the foundations of mathematics and logic through his philosophy of science to his work at Harvard on metaphysics and cosmology. Unlike Ford, Auxier and Herstein believe that Whitehead, in keeping with his mathematical training, published the organized results of his thinking, not the scattered pieces of its development (QE 26).

Much of their book focuses on explicating Whitehead’s non-metrical theory of extension. This is originally what drew my attention to their unpublished manuscript: my dissertation also attempts to make sense of this notoriously difficult but central feature of Whitehead’s thought. I describe his “extensive continuum” in my dissertation as a new kind of ether theory, comparing it to the ether theories of Plato (i.e., the Receptacle), Kant, Schelling, and Rudolf Steiner (see chapter 4 of my dissertation). This may seem like a stretch, but Whitehead does refer to the extensive continuum as an “ether of events” in An Enquiry Concerning the Principles of Natural Knowledge (1919) and in The Principle of Relativity (1922). He likely dropped the term in future books because of the way Einsteinian physicists ridiculed the old ether idea as akin to phlogiston, as it was made superfluous by Einstein’s special theory of relativity (despite the fact that Einstein himself claimed his general theory of relativity posited a “new ether”). But Whitehead’s novel ether theory is not the materialistic sort deployed by 19th century physicists, nor is it the relativistic sort deployed by Einstein.* Whitehead’s ether is not a physical “stuff” or space-time “fabric,” but a logical space or topological nexus allowing us to understand how self-creating actual occasions become coordinated participants in the same cosmic epoch. 

“We shall term the traditional ether an ‘ether of material’ or a ‘material ether,’ and shall employ the term ‘ether of events’ to express the assumption of this enquiry, which may be loosely stated as being ‘that something is going on everywhere and always.’ It is our purpose to express accurately the relations between these events so far as they are disclosed by our perceptual experience, and in particular to consider those relations from which the essential concepts of Time, Space, and persistent material are derived. Thus primarily we must not conceive of events as in a given Time, a given Space, and consisting of changes in given persistent material. Time, Space, and Material are adjuncts of events. On the old theory of relativity, Time and Space are relations between materials; on our theory they are relations between events” -Whitehead (Principles of Natural Knowledge 26).

The search for a proper theory of extension or spatiality was the guiding thread in all of Whitehead’s philosophizing, culminating in the infamously impenetrable Part IV of Process and Reality, wherein Whitehead invents what has since come to be called mereotopology (current applications include programming the visual systems of robots). But his magnum opus is titled Process and Reality, not Extension and Reality. Why?

In a second edition of Principles of Natural Knowledge (202), Whitehead writes:

“this book is dominated by the idea that the relation of extension has a unique preeminence and that everything can be got out of it. During the development of this theme, it gradually became evident that this is not the case…[T]he true doctrine, that ‘process’ is the fundamental idea, was not in my mind with sufficient emphasis. Extension is derivative from process, and is required by it.”

Auxier and Herstein remind students of Whitehead not to neglect his pre-Harvard “triptych” on the philosophy of science (Principles of Natural Knowledge [1919], The Principle of Relativity [1920], and The Concept of Nature [1922]) under the false assumption that he radically departs from these earlier texts in Process and Reality. All three of these books were written as a response to Einstein’s misguided identification of a preferred model of curved geometry with physical space-time (QE 30), but they carry forward physico-mathematical hypotheses that Whitehead had already been constructing for decades. Auxier and Herstein argue for the continuity of Whitehead’s thought by pointing out that already in A Treatise on Universal Algebra (1897) Whitehead was hard at work on the problem of spatiality (QE 63). I agree with them that Whitehead’s theory of extension is the golden thread linking his work in mathematics, physics, philosophy of science, cosmology, and metaphysics. There are no sharp breaks or revolutions in the story of his philosophical genesis, but there is evidence of a gradual shift in Whitehead’s thought toward an emphasis on the creative originality of process and its accretion of value over the pure possibility of extension. Yes: process requires extension to express itself. But extension, and the process of extensive abstraction by which we come to know anything about it, are functions of process. The primality of process or tension** as such over extension is part of what follows, I would think, from Auxier and Herstein’s stated radical empiricism, “that concrete existence explains the abstract aspects of experience and not vice-versa.”

My dissertation treats Whitehead’s process philosophy as a 20th century re-emergence of Schellingian Naturphilosophie. I thus treat Whitehead as a post-Kantian thinker, which is to say I read his philosophy of organism as an attempt to correct Kant’s wrong turn. Though there is little direct influence, I argue that Whitehead in effect follows Schelling by inverting the Kantian method, replacing transcendentalism with what I refer to as “descendental” philosophy. I do not believe this is the only fruitful way to interpret Whitehead’s contribution to modern philosophy, but given Auxier and Herstein’s criticisms of “habitual” readings of Whitehead as a post-Kantian (QE 35), I feel the need to defend my approach (see also pages 19-21 of my dissertation, which cites the earlier manuscript version of QE). While Whitehead does state in the first pages of Process and Reality that his philosophy of organism is a recursion to pre-Kantian modes of thought, I must disagree with Auxier and Herstein’s claim that Whitehead viewed his speculative philosophy as entirely unrelated to the Kantian project. On my reading, Whitehead explicitly and repeatedly engages with Kant’s transcendentalism throughout Process and Reality as well as other texts. I believe he did so because he recognized the significance of Kant’s Critique of Pure Reason for the pursuit of knowledge of Nature and the need to demonstrate the ways his own speculative thinking did not fall prey to transcendental illusions. It is true that “rationality” is entirely re-imagined by Whitehead in relational and radically empirical terms. His is a “critique of feeling” rather than pure Reason. Whitehead is a realist, but his realism does not ignore or recede from the challenge to knowledge of reality posed by Kant. Like Schelling, Whitehead wanted to respond to Kant, to point out and fix his errors, and to re-establish the possibility of rational cosmology, theology, and psychology on organic and aesthetic grounds. 

In addition to shedding much needed light on Whitehead’s theory of extension, Auxier and Herstein dismantle “model-centric” approaches to physics (including the standard model of gravitational cosmology), redefine naturalism in radically empiricist terms, and contribute profoundly to carrying forward Whitehead’s urgent call to secularize the concept of God’s functions in the world (see Process and Reality 207). I hope to offer further blog reflections on each of these topics in the coming weeks.

Back to teach at Schumacher College in April 2019: “The Evolution of Consciousness and the Cosmological Imagination”

I’ll be teaching another short course at Schumacher College in the UK the week of April 22nd-26th, 2019.

Here’s a link if you’re interested in registering:


Here’s what I’ll be teaching on:

“The Evolution of Consciousness and the Cosmological Imagination”

This week-long course will trace the evolution of consciousness in the West from ancient Greece through to the present. The goal is twofold: to understand the historical process whereby humanity severed itself from a meaningful universe and to re-ignite the cosmological imagination allowing us to reconnect to the soul of the world. The course begins by exploring Plato’s cosmology and theory of participation and moves on to consider the Scientific Revolution and the Romantic reaction to it. It concludes with a study of several contemporary efforts to re-enchant the cosmos by grounding human consciousness back in the more-than-human creative process responsible for generating it. In addition to Plato, the course draws upon the archetypal astronomy of Johannes Kepler, the Naturphilosophie of Goethe and Schelling, the nature poetry of Coleridge and Wordsworth, the esoteric philosophy of Rudolf Steiner and Owen Barfield, the process philosophy of Alfred North Whitehead, and the contemporary participatory theory of Jorge Ferrer.

Pre-Defense Dissertation Draft Completed

In this dissertation, I lure the process philosophies of F.W.J Schelling and A.N. Whitehead into orbit together around the transcendental philosophy of Immanuel Kant. I argue that Schelling and Whitehead’s descendental aesthetic ontology provides a way across the epistemological chasm that Kant’s critiques opened up between experience and reality. While Kant’s problematic scission between phenomena and the thing-in-itself remains an essential phase in the maturation of the human mind, it need not be the full realization of mind’s potential in relation to Nature. I contrast Schelling and Whitehead’s descendental philosophy with Kant’s transcendentalism by showing how their inverted method bridges the chasm—not by resolving the structure of reality into clear and distinct concepts—but by replanting cognition in the aesthetic processes from which it arises. Hidden at the generative root of our seemingly separate human capacities for corporeal sensation and intellectual reflection is the same universally distributed creative power underlying star formation and blooming flowers. Human consciousness is not an anomaly but is a product of the Earth and wider universe, as natural as leaves on a tree. Through a creative interweaving of their process-relational orientations, I show how the power of imagination so evident in Schelling and Whitehead’s thought can provide philosophy with genuine experiential insight into cosmos, theos, and anthropos in the aftermath of the Kantian revolution. The two—anthropos and cosmos—are perceived as one by a common sense described in this dissertation as etheric imagination. This etheric sense puts us in touch with the divine life of Nature, which the ancients personified as the ψυχὴ του κόσμου or anima mundi.

Etheric Imagination in Process Philosophy from Schelling and Steiner to Whitehead

I’ve just submitted my dissertation proposal for review. Click on the title below for the PDF.

Etheric Imagination in Process Philosophy From Schelling and Steiner to Whitehead

I welcome suggestions, critiques, sources, and/or extensions.

Basically, I’m doing a comparative study of the philosopher Friedrich Schelling, the esotericist Rudolf Steiner, and the mathematician and cosmologist Alfred North Whitehead. In particular, I want to interpret their respective “etheric” ontologies (Schelling’s “world-soul/universal organizing principle,” Steiner’s “etheric formative forces,” and Whitehead’s “evental ether/Creativity”) as typical of the process-relational imagination.
