Here’s the recording of a lecture that Becca Tarnas and I delivered last night for the Atlanta Astrological Society.

“The doctrine of relativity affects every branch of natural science, not excluding the biological sciences. . . . Relativity, in the form of novel formulae relating time and space, first developed in connection with electromagnetism. . . . Einstein then proceeded to show its bearing on the formulae for gravitation. It so happens therefore that owing to the circumstances of its origin a very general doctrine is linked with two special applications.”
–Whitehead (The Principle of Relativity, 3).

One of the biggest surprises for me upon reading Auxier and Herstein’s book The Quantum of Explanation was learning that Whitehead’s theory of extension (or “mereotopology” as it has come to be called) has been taken up by computer scientists working in the field of robotic vision (see for example the work of Ian Pratt-Hartmann).

“It is a widely acknowledged fact in this sub-discipline that Alfred North Whitehead’s work on extension is foundational for their enterprise. Our experience has been that Whitehead scholars are simply astounded to learn of this fact. Yet we should have expected and even predicted such a connection” (QE 90).

Guilty as charged. While I think I got things mostly right in section 3.2 of my dissertation (“From Geometric Conditions of Possibility to Genetic Conditions of Actuality”), the promising application of Whitehead’s topological scheme to robotic vision certainly brings this aspect of his project into sharper focus for me. As a radical empiricist, Whitehead was searching for a formal account of our concrete experience of projectively related extensa. We are finite creatures with limited sensory organs and processing capacity. We do not experience the world of spatial relations in terms of infinitesimal points or the geometrical schemes built up from such points. Rather, what we encounter in our immediate experiential field are the intuitive whole-part relational structures formalized by non-metrical projective geometry.

Following Einstein’s articulation of the special and general theories of relativity (in 1905 and 1916, respectively), and his problematic “mono-metric” identification of a 4-D geometrical model with physical space-time*, Whitehead pursued his theory of extension with renewed urgency. Somehow, the uniformity of spatial geometry had to be preserved, else scientific measurement would become impossible. Einstein did not appear to realize that allowing the contingent warping of space by massive objects undermined the fundamental logical requirements of measurement: that space have a necessary and universal structure (or, as Auxier and Herstein put it, “we must have a standard unit of spatial comparison for conjugacy…and standard(s) of spatial projection” so as to bring this unit into comparison with whatever we are trying to measure [QE 102]). By collapsing the difference between physical space and his favored geometrical scheme, Einstein made the structure of spatial geometry contingent upon randomly arrayed masses.

“We must know the complete distribution of matter and energy in the universe prior to knowing its geometry. But we must have a comprehensive grasp of this geometry in order to discover this distribution. As Whitehead pointed out, with General Relativity as our theory of space and gravity, we are saddled with a situation where we must first know everything before we can know anything” (QE 104).  

Einstein’s “mono-metric” model has been one of the most successful in the history of science. But because of the unexpected observations of the rotational velocity of galaxies and of cosmic inflation rates, its theoretical supremacy has begun to be seriously questioned. Some astrophysicists have attempted to save the theory by inventing “dark matter” and “dark energy” to explain the missing mass that would bring observations back into agreement with Einstein’s theory. Auxier and Herstein refer to these inventions as “an especially unhappy piece of nonsense” (QE 20). I’m sympathetic, but I wouldn’t go quite that far. To my mind, these invented entities are akin to the epicycles of Ptolemaic astronomy. In other words, these exotic and invisible forms of mass/energy (which supposedly compose ~96% of the universe) are postulated ad hoc in an attempt to “save the appearances” (as ancient astronomers used to say). Ancient astronomers were tasked by Plato with explaining the seemingly erratic motion of the planets in terms of a theoretical model composed only of uniform circular motions. When new planetary observations conflicted with the model, more circles were added (epicycles) to bring the model back into alignment with appearances. One view of science is that it is just about refining existing theoretical presuppositions to fit new observations, gradually approaching a perfect identity between model and reality. In this sense, the addition of epicycles to match observations could continue indefinitely. After all, Ptolemy’s geocentric model was more accurate than Copernicus’ heliocentric model (which itself still required epicycles until Kepler and Newton updated his math). The geocentric model is still accurate enough that modern planetarium projectors (invented in the 1920s by a company in Jena, Germany) continue to utilize it, reproducing Ptolemy’s deferents and epicycles with their internal gears and motors (see also).


But as Karl Popper taught us, scientific theories must be subject to empirical falsification. The eternal circular orbits of Ptolemy’s model fall out of phase with the long-term evolution of planetary orbits, while the (updated) heliocentric model accommodates this evolution well. As Thomas Kuhn, another great philosopher of science, taught us, the history of science is not just about the gradual refinement of old theories to fit new observations in an asymptotic convergence of model to reality; rather, this history is also characterized by periods of revolutionary crisis as aging paradigms are supplanted by deeper, wider, more elegant and inclusive explanatory perspectives. Einstein’s genius was to bring the reigning Newtonian theory of gravity into alignment with Maxwell’s theory of electromagnetism. A deeper theory of space was born. But in a sense, despite many other successful observational predictions, empirical falsification is exactly what happened to Einstein’s gravitational theory when it failed to accurately predict the observed rotational velocity of galaxies. However, because this darling model had made a number of other accurate predictions, and because no widely accepted alternative paradigm was on hand, astrophysicists decided to fudge the numbers by inventing new free parameters, new epicycles, to bring the theory back into alignment with observations. Appearances were thereby saved, but at the cost of conjuring into existence an entire universe (or 96% of one, at least) of cold and dark, that is, unobservable, matter/energy.

Even though he did formulate a “bimetric” alternative in 1922 (QE 109), Whitehead’s problem is not with Einstein’s model. This isn’t a “scientists have been wrong before, so why should we trust them now?” argument. Science is about modeling. In some sense, scientific models are always wrong. That’s the name of the game, after all: build a model and throw it against reality until it breaks. Then study why it broke until you find a new model that doesn’t break as quickly. Gradually, more robust, inclusive models emerge. Rather, Whitehead’s problem is with the philosophically naive “model-centrism” that leads scientists to equate their favored model with reality in a dogmatically literalistic way. We should never assume the reigning physical models of the universe offer a final account of the way things are (especially when today’s two most successful models, relativity and quantum theory, remain irreconcilable). Science is not ontology: science is a method of inquiry involving the making and breaking of toy models.

The dogmatic equation of a favored geometrical model with physical reality not only undermined the logical basis of measurement, it led Einstein to dismiss our concrete experience of an irreversible flow of time as nothing more than a “stubbornly persistent illusion.” This is Whitehead’s famous “fallacy of misplaced concreteness” writ large. Einstein’s unquestioned commitment to the classical “spectator theory of knowledge” prevented him from grasping the profoundly relational implications of his new theory of space. He upheld the old Galilean-Cartesian view of a bifurcated Nature, construing our consciousness as somehow external to a cosmos that we can only ever confusedly experience. Whitehead offers an alternative, fully relational epistemology and ontology that re-embeds experience in the cosmos: we are creative participants in a cosmogenetic relational nexus.  

Instead of rushing to eliminate experience from our understanding of a relativistic (or relational) reality, Whitehead carefully examined the hidden epistemic presuppositions and metaphysical requirements of Einstein’s more specific application of relativity to the physics of light and gravitation. The result of his examination was eventually assembled in Process and Reality as the fourth category of explanation, a truly general principle of relativity: “it belongs to the nature of a ‘being’ that it is a potential for every ‘becoming'” (PR 22). Obviously, the importance of Whitehead’s fourth category of explanation (of which there are 26 others) can only be understood within the total gestalt of his categoreal scheme (which includes the category of the ultimate: Creativity; eight categories of existence, among which the most important are eternal objects and actual occasions; and nine categories of obligation). Whitehead’s categoreal scheme is laid out in Part I of Process and Reality as something like an opening credit roll listing the conceptual dramatis personae who, in Part II, will take the stage to exemplify their adequacy. But I’m not going to run through the whole dress rehearsal right now (for a helpful exegesis of Whitehead’s first four categories of explanation, see pgs. 108-110 of QE). Suffice it to say that Whitehead’s principle of relativity expresses the truth that everything co-exists in a web of relatedness, whether actually or potentially. 

Auxier and Herstein:

This is the principle that Einstein and his devotees have abandoned: not the mathematical expression of their physical model; that model is itself only an application of what has become the standard dogma of orthodox cosmology, with its narrowly defined approach to the interpretation of a truncated representation of experience. Rather, physical cosmology has left behind the full principle of relativity and its unqualified commitment to the incurable relatedness of the real. That abandonment comes in the truncation of experience at the root of their largely unexpressed theory of experience [i.e., the theory of the bifurcation of Nature]. For one cannot have a universal principle of relativity—applicable to all that is real—unless one takes experience in its real, relational totality. Experience—both actual and potential—is exactly the kind of reality that falls under the principle of relativity. One cannot take the metaphysical principle of relativity seriously unless one is a radical empiricist” (QE 110). 

In The Quantum of Explanation, Auxier and Herstein have brilliantly succeeded in elucidating the features of a radically empirical cosmology. As Whitehead reminds us early and often in Process and Reality, the purpose of philosophy is not to explain away the existence of the concrete by reduction to the abstract, but to explain the emergence of abstraction from concretion. The proper questions are: how does concrete fact participate in general form and how are general forms exemplified in concrete facts?

For a longer discussion of Whitehead’s radical empiricism a.k.a. relational realism, see my essay “Retrieving Realism: A Whiteheadian Wager.”

*It has been brought to my attention that the matter of whether Einstein thought the physics of gravitation is reducible to the geometry of space-time is not so clear cut. See for example: “Why Einstein did not believe that general relativity geometrizes gravity” by Lehmkuhl. The research continues… 

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

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.

[Update 4/19: listen to the interview here]

On Thursday at CIIS, I’ll interview physicist and novelist Alan Lightman, author of the just published Searching for Stars on an Island in Maine (2018). As of this writing, Lightman’s book is #1 in Metaphysics on* 


Lightman begins his reflections in a cave in Font-de-Gaume, France, famous for its adornment of ochre and charcoal painted animal forms left behind by its long deceased Paleolithic inhabitants. Lightman’s cave visit inspires musings about how these primal people may have imagined the meaning of their existence. It is as though our species has always been inspired by two great mysteries (though each age further refines its understanding of them): by the unconscious depths within our psyches and by the ever-expanding edges of the evolving cosmos. We are lured deep into dark labyrinthine caves to paint Living Forms on fire-lit walls, and we are drawn skyward toward ancestral light in an attempt to calculate the spiraling of stars. Creation and discovery, art and science. Homo sapiens seems caught in a “necessary tension” between the two. With one foot aloft in a spiritual world of eternal Absolutes and the other firmly planted in a perpetually perishing material world, we stumble along through history.

Toward what? 

Lightman doesn’t pretend to have any answers, but his ruminations functioned to heighten my sense of the importance of the questions. Is there any meaning in it all? Or is it just material? Even if it is all just material, isn’t it still beautiful, anyway? Depending on our personal proclivities, the existential tension produced by such questions can either release us into enchantment with mysterious paradox or entrap us in the frustration of irresolvable contradiction. Our nature is not a unified essence. We are tripartite: artists striving to enjoy and express nature’s beauty, scientists trying to explain its necessary truths, and priests longing to embrace and be embraced by its goodness. Expression, explanation, embrace. Beauty, truth, goodness. Art, science, religion. How are these human ideals connected? Must one or the other of them dominate, or is some integral harmonization possible? Can our search for hard scientific truth be made to cohere with our longing for meaning and our love of beauty? 

Lightman moves from curiosity concerning the spirituality of the ancients to recounting his own mystical experience. One night, while he was piloting a small boat on the way to his cabin on Pole Island, he was struck by the desire to turn off the lights and cut the engine of his vessel. He laid down on the deck to gaze up at the stars in silent contemplation. It wasn’t long before the boat, his body, and any sense of separation from nature dissolved. He began to feel like he was “falling into infinity.” A spiritual sensation of cosmic kinship with the stars overtook him. 

Unlike many theists, whose faith in a personal God originates in such experiences of overpowering transcendent unity, Lightman did not draw religious conclusions from his celestial vision. He remains committed to a purely scientific view of the world, a view he has held since his childhood experiments with petri dishes and pendulums. He references Freud’s reductive view of such “oceanic feelings,” accepting that his experience of the infinite may be nothing more than an infantile desire to crawl back into his mother’s womb. Despite this possible interpretation, his personal experience of being swallowed whole by the sky has allowed him to at least understand the power and allure of religious belief.

“The materiality of the world is a fact, but facts don’t explain the experience.”

Lightman admits that even science is founded on a kind of faith, a faith in what he calls “the Central Doctrine of Science,” that all physical events are governed by universal and necessary laws, or mathematical patterns, that hold everywhere in observable time and space. Because of this scientific faith, he can imagine no “miracles,” or seemingly unexplainable supernatural events. Any such event, while perhaps surprising at first, should be treated as nothing more than an opportunity to refine and expand the laws of physics.

He contrasts the theological certainty of Augustine with the geometrical certainty of Euclid. In Lightman’s view, Augustine’s certainty, rather than a product of divine revelation, is nothing more than fervently held personal opinion. Science, on the other hand, is empirically validated and mathematically proven. 

“Theoretical physics is a temple built of mathematics and logic and aesthetics.”

Lightman contrasts the process of scientific discovery with that of artistic creation. Whereas the artist’s creativity, even if rooted in some sort of transcendent experience, remains purely subjective or internal, transcendent moments of discovery in science are both inner and outer, at once subjective and objective. Scientific inspiration has a “vital connection to the physical world,” and thus operates as a kind of “double discovery”: the inner mental world aligns with and thus reveals to consciousness the mathematical truth of the outer material world.

Lightman recounts the history of modern science and the way its discoveries decentered and humbled the human being. After Copernicus, Kepler, Bruno, Galileo, and Newton, it became more difficult for humans to imagine themselves as the uniquely special creation of a personal God. We now know (as Bruno was among the first to speculate) that there are countless other planets that are potentially habitable. Life, even intelligent life, may be pervasive in the universe. We are hardly special.

Lightman views death not as an on/off switch, but as a gradual process of disassembly of the atomic assemblage that, for a time, constitutes who and what we are. Consciousness, he wagers, is just an illusion, a word we use to describe the “mental sensation” of electrochemical flows of neurons in the brain. He claims to be “content with the illusion of life,” with the idea that he is but a “self-referencing machine.” Strangely, however, he is a machine with feelings. Even if illusory, our “mental sensations” remain undeniable. Lightman reframes Descartes’ argument for the reality of the soul: instead of “I think, therefore I am,” it becomes “I feel, therefore I am.” He accepts that, since he cannot escape the feeling of being alive, of life’s joys and sorrows, it hardly matters whether he is actually a soulless machine or not. He may as well find ways to maximize pleasure and minimize pain. Despite the illusory nature of consciousness, the neural sham of selfhood, Lightman thinks morality can still be grounded on this simple hedonistic principle.

Lightman ponders the source of our universe’s apparent “fine tuning,” the fact that, were any of the fundamental physical constants even the slightest fraction different from their observed values, life and consciousness could never have emerged. The multiverse theory is offered as one possible explanation, that is, that our universe is just one of infinitely many universes to have randomly emerged from the quantum vacuum, and we just happen to be in one of the rare worlds where the constants aligned just right so as to produce creatures capable of reflecting on this fact. But since it is impossible to test whether or not other universes exist, and because the theory offers a pseudo-explanation rooted in pure chance rather than causal necessity, Lightman is unsure whether it can really be considered scientific. In the end, when physical science reaches the question of the origin of the universe, of why there is something rather than nothing, Lightman admits that philosophy and religion still have a role to play.

While I have some problems with his view of humanity’s place in the universe, I appreciate Lightman’s acknowledgement that philosophy, and even religion, still have a place in human life (at least so long as they avoid making false claims about the physical world). This is far better than some popularizers of science, like Neil deGrasse Tyson, Lawrence Krauss, and Richard Dawkins, who tend to dismiss philosophy and ridicule religion.

I would like to ask Lightman whether he thinks we could ever finally define the meaning of “physical” without doing metaphysics. Physicists can bracket many of philosophy’s more nebulous questions to pursue their precisely defined experimental measurements and build their mathematical models, but at the end of the day, their theoretical definitions inevitably fade off into metaphysics around the edges. I have a few philosophical objections to some of what Lightman seems to take to be incontestably scientific claims. He sometimes wanders into metaphysics without explicitly realizing it, particularly when he discusses consciousness and the mind/body problem. 

Lightman emphasizes the mere materiality of everything we experience: our personal identity is nothing but neurochemistry; the enchanting beauty of an island-enveloping fog is really just minuscule droplets of water adrift in the wind; the magical bioluminescent shimmering of the ocean is just little bugs in the water, etc. “It’s all material.”

He grants that “the human body is the most amazing and baffling phenomenon of the material world,” but still, he reminds us, it is all just molecules and chemicals, just atoms out for a swerve in the void.

Nearly a century ago, just as the relativistic and quantum revolutions in science were beginning to sink in, another mathematical physicist-turned-philosopher Alfred North Whitehead offered an alternative reading of the scientific evidence:

“It is the accepted doctrine in physical science that a living body is to be interpreted according to what is known of other sections of the physical universe. This is a sound axiom; but it is double-edged. For it carries with it the converse deduction that other sections of the universe are to be interpreted in accordance with what we know of the human body” (PR 119).

“We think of ourselves as so intimately entwined in bodily life that a man is a complex unity–body and mind. But the body is part of the external world, continuous with it. In fact, it is just as much part of nature as anything else there–a river, or a mountain, or a cloud. Also, if we are fussily exact, we cannot define where a body begins and where external nature ends” (MT 21).

“The human body provides our closest experience of the interplay of actualities in nature…Analogous notions of activity, and forms of transition, apply to human experience and to the human body. Thus bodily activities and forms of experience can be construed in terms of each other. Also the body is part of nature. Thus we finally construe the world in terms of the type of activities disclosed in our intimate experience” (MT 115).

I am in agreement with Lightman that Descartes’ mind/body dualism is unacceptable. Somehow, the mental activities disclosed in our personal experience must be intimately connected with the physiological activities of our body. Like Lightman, I reject vitalistic interpretations of living organisms, where some extra spirit or vital force is thought to inhabit and organize the material body. Physical activity is the same, whether it takes place inside or outside the skin of a living organism. It’s all matter. But “just” matter? “Mere” matter? “Nothing but” matter? Why must we take such a deflationary view of materiality when, as the evidence of our own intimate experience makes clear, matter is capable in some of its forms of nothing less than conscious reflection and intelligent deliberation? What is to prevent us, like Whitehead, of generalizing from our own experience so as to recognize that all matter is to some extent experience-imbued?  

Even if we were to accept Lightman’s deflationary view of matter as just dead stuff, and of our consciousness as a linguistically produced illusion, we are still left having to explain how mere molecules could give rise to the illusion of consciousness. Whether the mind has real causal influence, or is merely an epiphenomenal hallucination, how is it that neurons generate mental sensations at all? Feelings arise as self-evident, with their own phenomenological warrant, regardless of any materialist conjectures regarding their real underlying causes. Even if they were ultimately “illusory,” reducible to some purely material level of reality, we still feel them. The “illusion” at least appears, and is thus real enough to require explanation. But I’ve yet to come across a scientific theory of how extensional lumps of matter could produce even the illusion of emotions and mental intentions. Rather than trying to solve this “hard problem,”  what is to prevent us from accepting Whitehead’s converse deduction, that our bodily experience grants us insight into the intrinsic nature of matter, a nature that the overly abstract Cartesian view of its extrinsic nature totally misses? What if matter is itself somehow intrinsically mindful or sentient, and gradually increases its experiential intensity as more complex organic forms evolve? Such a view would in no way contradict the known scientific evidence. It just offers an alternative metaphysical interpretation of what we already know about the physical world, an interpretation that allows us to avoid the absurdity of having to deny the reality of our own most intimate experience of being alive. Instead of the reductive nihilism of eliminative materialism, why not the re-enchantment of evolutionary panpsychism?

Such an alternative interpretation is strengthened by revisiting the origin story of modern science. The early modern founders of the scientific worldview were not as soberly positivistic as they are often made to seem. Copernicus’ acceptance of the heliocentric theory was motivated not by its improved predictive power (Ptolemy’s model remained more accurate until Kepler’s and Newton’s later adjustments), but by his spiritual commitment to Neo-Platonism.  Similarly, Kepler perceived not just mathematical harmony in the heavenly orbits, but their archetypal music. His astronomical science was practiced right alongside his astrological divination. Galileo, too, was a practicing astrologer. His book Starry Messenger includes a dedication to Cosimo de’ Medici that details the prominent placement of Jupiter in his natal chart.Giordano Bruno was a panpsychist magician (not to mention a political radical). Newton was an alchemist. Sure, we could dismiss their strange mystical proclivities by saying they were all transitional figures, not yet fully modern. But we could also acknowledge that an enchanted cosmology need not preclude scientific investigation. Indeed, in the case of these early founders, it seems to have motivated it!

For these early scientists, the lawful mathematical order of the universe was highly suggestive of its intelligent construction by God. From Whitehead’s perspective, there is a direct line of descent from the medieval theological doctrine of an omniscient and omnipotent God concerned with and in charge of every detail of the created world to the modern scientific faith in the lawful ordering of nature (“faith in the possibility of science is an unconscious derivative from medieval theology” [SMW 13]).

Lightman’s compromise between science and religion has it that the former concerns objective truths about the physical world, while the latter concerns subjective or personal truths about the spiritual world. The truths pursued by each need not compete since they exist in entirely distinct domains. While this position, similar to Stephen J. Gould’s notion of non-overlapping magisteria, is far superior to the aggressive atheism proffered by the likes of Dawkins and Sam Harris, I prefer to seek a more integral solution that situates human spirituality within the same evolving cosmos known to science. Rather than two worlds, one physical and the other spiritual, I inherit Schelling’s view:

“Nature is visible Spirit; Spirit is invisible Nature.”

This is not to say that the claims made by religious believers ought to be treated as epistemologically equivalent to the claims of natural scientists, especially when it is a question of experimentally testable hypotheses. If the claims of a religion are in conflict with those of a widely accepted scientific fact or theory, it is religious dogma that must bend. Whitehead again:

“Religion will not regain its old power until it can face change in the same spirit as does science. Its principles may be eternal, but the expression of those principles requires continual development” (SMW 234).

That said, modern materialistic cosmology must find a way to make room for human meaning and consciousness. Our meaning-making must of course be informed by modern scientific discoveries, but it cannot be explained away as entirely illusory. [I unpack Whitehead’s attempt to make room in Physics of the World-Soul (2016)].

At least on our planet, cosmic evolution has produced conscious human beings. All the evidence suggests that something similar may be happening on countless other planets. Life and consciousness may be just as pervasive as atoms and stars. To my mind, this fact is not evidence against the existence of a meaningful cosmos or even of a personal God. It could also be interpreted as evidence for an immanent evolutionary aim toward personalization**,  and for a far less provincial, truly infinite divinity.

Even in such an enchanted cosmos, our species may be doomed to go extinct. We may be no more than a passing evolutionary phase, as Lightman suggests, destined to be replaced by “Homo techno” in a few generations. But letting go of our anthropocentrism need not leave us with a sense of purposelessness. Even if our species goes extinct, other intelligences surely populate this universe. And even if death is the end of our individual egos, in a panpsychist cosmos, sentience never fully evaporates.

*Interestingly, #2 is Sarte’s Being & Nothingness and #3 is Robert Lanza’s Beyond Biocentrism: Rethinking Time, Space, Consciousness, & the Illusion of Death–two radically different philosophical orientations on ultimate reality. 

**As William James suggested, we can view nature as composed “of personal lives (which may be of any grade of complication, and superhuman or infrahuman as well as human), variously cognitive of each other…, genuinely evolving and changing by effort and trial, and by their interaction and cumulative achievements making up the world” (Collected Essays and Reviews, 443-444).

Below is a lecture recorded for the online course PARP 6060 02 – Introduction to Philosophy, Cosmology, and Consciousness at

I first discuss the meaning of philosophy from a Whiteheadian perspective, then run through a brief history of philosophy as relevant to process thought (Parmenides, Heraclitus, Plato, Aristotle, Copernicus, Descartes, Newton, Kant and his immediate successors), and finish by offering a few key perspectives from Whitehead’s cosmological scheme.

Many streams of thought flow into and give shape to PCC’s perspective on the Universe and our human place within it. One of these streams is the process-relational tradition. This tradition is most often associated with the 20th century mathematician and philosopher Alfred North Whitehead (1861-1947), but many of Whitehead’s core insights can be traced back to the beginnings of Western philosophy in ancient Greece, and were carried forward and brilliantly developed by the German Idealists in the early 19th century. 

I hope my lecture helped give you some sense for the philosophical lineage that Whitehead drew upon and entered into dialogue with when he articulated his post-relativistic, post-quantum cosmological scheme in the 1920s and 30s. I have a feeling you agree, after reading the chapters I assigned from his book Modes of Thought (1938), that Whitehead is not an easy thinker to understand. But as someone who has been studying his work for almost a decade now, I can assure you it is well worth the effort to get to know the intimacies of his metaphysical scheme. Almost always it takes multiple readings to grok what he’s on about. All scientists employ instruments to aid them in their study. Philosophy’s instrument of inquiry, according to Whitehead, is language itself. Just like telescopes and microscopes, it takes a bit of practice to learn how to see with them. I encourage you to take Whitehead’s experiments in language seriously, even if they at first seem confusing. 

Whitehead boldly re-affirmed the grand tradition of speculative cosmology at a time when most academic philosophers were retreating from metaphysics into reductionistic materialism and logical positivism. Whitehead summed up the situation of his contemporaries: “…the science of nature stands opposed to the presuppositions of humanism. Where some conciliation is attempted, it often assumes some sort of mysticism. But in general there is no conciliation” (MoT 136). Modern science tells us we are matter in motion, while modern humanism insists we are free agents enjoying profound emotions. While the positivists busied themselves analyzing linguistic puzzles, pretending not to be metaphysical by ignoring the mind/matter dualism implicit in all their reasonings, Whitehead sought insight into creative depths as yet unspoken. Logical positivism attempted to reduce philosophy to the safety of settled science; Whitehead sought instead to engage philosophy as a poetic adventure in world-making. 

“In my view the creation of the world is the first unconscious act of speculative thought; and the first task of a self-conscious philosophy is to explain how it has been done” (Aims of Education 164).

Whitehead’s cosmological vision is bold, but he may also deserve the title of humblest philosopher in history. “Philosophy begins in wonder,” he tells us. “And, at the end, when philosophy has done its best, the wonder remains” (MoT 168). “How shallow, puny, and imperfect are efforts to sound the depths in the nature of things,” he tells us elsewhere. “In philosophical discussion, the merest hint of dogmatic certainty as to finality of statement is an exhibition of folly” (PR xiv). For Whitehead, philosophy’s aim is to purify emotion by eliciting some increase of understanding, to correct the initial excess of subjectivity in our consciousness so as to grant us a more cosmic perspective on reality. “Purifying” emotion doesn’t mean eliminating it by replacing it with logic; even knowledge, for Whitehead, is a complex form of feeling. The goal of “knowing” is not to explain the All once and for all (impossible in the open-ended, creative cosmos Whitehead imagines), but to elucidate our experience so as to bring more of the Great Mystery’s beauty into our awareness. 

Philosophy is akin to imaginative art, Whitehead tells us. It is the endeavor to creatively reframe naive experience so as to intensify our enjoyment of the meaning and potential of our existence. None of this is to say that Whitehead ignores the importance of science: “I assume as an axiom that science is not a fairy tale” (The Concept of Nature 40). Whitehead turned to philosophical cosmology late in his life (after a illustrious 30 year career as a Royal Society elected mathematician) precisely in order to save 20th century natural science from incoherence. He wanted to provide physics with a new and more adequate metaphysical foundation after quantum and relativity theories spelled the end of the Newtonian paradigm.

“In the present-day reconstruction of physics fragments of the Newtonian concepts are stubbornly retained. The result is to reduce modern physics to a sort of mystic chant over an unintelligible Universe. This chant has the exact merits of the old magic ceremonies which flourished in ancient Mesopotamia and later in Europe. One of the earliest fragments of writing which has survived is a report from a Babylonian astrologer to the King, stating the favorable days to turn cattle into the fields, as deduced by his observations of the stars. This mystic relation of observation, theory, and practice, is exactly the present position of science in modern life, according to the prevalent scientific philosophy. The notion of empty space, the mere vehicle of spatial interconnections, has been eliminated from recent science. The whole spatial universe is a field of force, or in other words, a field of incessant activity. The mathematical formulae of physics express the mathematical relations realized in this activity. The unexpected result has been the elimination of bits of matter, as the self-identical supports for physical properties. At first, throughout the nineteenth century, the notion of matter was extended. The empty space was conceived as filled with ether…The more recent revolution which has culminated in the physics of the present day has only carried one step further this trend of nineteenth century science…Matter has been identified with energy, and energy is sheer activity; the passive substratum composed of self-identical enduring bits of matter has been abandoned, so far as concerns any fundamental description…The modern point of view is expressed in terms of energy, activity, and the vibratory differentiations of space-time. Any local agitation shakes the whole universe. The distant effects are minute, but they are there. The concept of matter presupposed simple location. Each bit of matter was self-contained, localized in a region with a passive, static network of spatial relations, entwined in a uniform relational system from infinity to infinity and from eternity to eternity. But in the modern concept the group of agitations which we term matter is fused into its environment. There is no possibility of a detached, self-contained local existence. The environment enters into the nature of each thing” (MoT 138).

Whitehead’s process-relational philosophy is an attempt to integrate the latest scientific evidence with our moral, aesthetic, and spiritual intuitions regarding the ultimate nature of the Universe. Whitehead envisions the Universe as a creative becoming, a cosmogenesis. The creatures who inhabit his world are bound up together in an infinite web of evolving relations. Reason has often functioned to alienate humanity from its relations, but Whitehead offers another possibility. Whiteheadian rationality is guided by its commitment to relationality, whereby “there is an essence to the universe which forbids relationships beyond itself” (PR 4). To search for a “beyond” is to violate the rationality of cosmic relationality. Any truth philosophy may seek can only ever be found here among us.

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.

Without the intellectual encouragement and personal friendships of Jake Sherman, Sean Kelly, Fred Amrine, Brian Swimme, Robert McDermott, Eric Weiss, Elizabeth Allison, and Rick Tarnas, this dissertation could not have been written. Thanks to each of them, and also to the entire community of students in the Philosophy, Cosmology, and Consciousness Program for sharing their philosophical passion and for the conversations that helped spark many of the ideas expressed in what follows. Thank you, finally, to my fiancée Becca for her inspiring imagination, for her encouragement, and for her patience as I labored over drafts of this text for so many consecutive weeks.

Following up on my contribution to the Latour/AIME reading group, I wanted to say a bit more about the confused concept called “matter.” There are many varieties of materialism, but for the sake of time, let’s follow Robert Jackson by dividing them up into two basic categories: 1) that variety of materialism which understands matter as some ultimate stuff that all emergent forms can be reduced to, 2) that which understands matter as some primordial formlessness, or endlessly differentiating movement from out of which all form emerges.


While I’m committed to articulating a realist ontology (my dissertation draws on Schelling and Whitehead in pursuit of what you might call an ontology of organism), I’d argue that to be real is not necessarily to be material, especially if matter is conceived of as a fundamental stuff. If we insist on continuing to employ the words “mind” and “matter” in metaphysical discussions, I’d want to construe them not as separate substances in a dualist ontology, but rather as reciprocal poles in an ontology of becoming, where “matter” signifies the accumulated weight of the stubborn facts of the past, while “mind” signifies the novel forms yearning for realization in the future. Every passing moment, or drop of experience, exists in tension between the two poles, fact and form, or actuality and potentiality. Matter, then, is only half the picture. A universe of only material things would be a universe where everything had already been actualized such that nothing new could ever emerge. All that could occur would be the rearrangement of the same old matter. There are plenty of thinkers who would disagree with me. For example, see Levi Bryant’s recent post.

Bryant seems to want to defend a non-reductive version of the first type of materialism. Contrary to my claim that materialistic atomism makes real emergent novelty impossible, Bryant writes:

…it’s difficult to see how this criticism hits the mark with the atomistic materialism of thinkers such as Democritus, Epicurus, and Lucretius.  Lucretius, for example, is quite clear that relations between atoms are every bit as important as the atoms themselves.  In example after example he discusses emergent entities that manifest powers (capacities) and properties only when atoms are arranged [or organized] in these particular ways…certain objects are only possible through certain relations.

I’ve probably got much to learn from Bryant about the Greek atomists. So my response here as much a query as a claim. I am aware that the third necessary ingredient in Lucretius’ scheme (aside from atoms and the void) is the clinamen. Atoms have an unexplained tendency to swerve as they fall through the void. According to Lucretius, without the clinamen, “nature would have never produced anything” (ii. 216-224), since no interaction would ever have occurred between atoms to allow for material organization. Leaving aside the equally puzzling question as to where atomic weight comes from or why atoms should be falling, we might also ask what the cause of this swerve, and so of material organization, is. Why do otherwise inert atoms have such a strange inclination for “curved” motion? Why does matter tend to turn in on itself? Lucretius seemed content to say it was simply “chance.” Chance, I suppose, means “for no reason at all.” Perhaps a strange swerving deserves an equally strange story. But we could tell other stories that make more sense. Dante might identify the cause of the clinamen with the Primum Mobile, the final sphere of the heavens whose divinely inspired motion initiates and sustains the motion of all the spheres it encloses (Paradiso, Canto XXVII). Of course, modern cosmology has outgrown Dante’s ancient geocentric imagination. We need a new creation myth to account for the strange inclinations of matter, a story more credible than the rather mechanical cosmos of revolving crystalline spheres first described by Aristotle and Ptolemy. I imagine Bryant would disagree with the need for a story in ontology, but then again, Lucretius articulated his ontology in the form of an epic poem. When it comes down to it, every metaphysician needs to give narrative force to their ontology by way of some ultimate reason(s) for which no reason can be given (other than givenness itself). For Whitehead, the ultimate reasons are aesthetic (Eros, Beauty), while the main characters in his cosmic plot are Creativity and Actuality. For Plato, the ultimate reasons are moral (Goodness, Truth), while his main characters are Nous and Chora.

Bryant says Lucretius finds relations to be as important as atoms. Does this mean relations are just as real as atoms? If so, perhaps the cause of the clinamen, and by proxy of nature’s emergent hierarchy of complexity, has something to do with an inclination to relate. “Chance” seems to me to be a poor explanation for such an inclination. Throwing our hands up by claiming such an all-pervasive swerve is random seems to me to be a rather anti-metaphysical, even anti-scientific, move. The tendency to relate must have a cause. There must be some account we can give of it that aligns with our understanding and coheres with our experience. Such an inclination, or tendency, may be motivated by what Whitehead, after Plato, called Eros. For Dante, Eros is “the love which moves the sun and other stars” (Paradiso, Canto XXXIII, lines 142-145). Love requires freedom, so this story concerning the cause of the clinamen need not neglect the uncertainty of atomic motion. All that I’d want to add to Lucretius’ account of atomic motion is relational emotion. This brings his ontology rather close to Whitehead’s processual atomism. How close depends on whether we are willing to say relations are just as real, and just as primordial, as atoms. Whitehead’s process-relational scheme includes both internal relations and external relations. On Bryant’s reading, Lucretius would seem to leave no room for internal relations: atoms can only collide; they cannot collude (they can only relate externally via efficient causation; they cannot relate internally via erotic play).

I’m hoping Bryant will clear up my queries concerning Lucretius. I’m ready to stand corrected about his lack of a coherent explanation for the clinamen. I would want to argue, however, that Bryant has misunderstood the second type of materialism listed by Jackson. Bryant writes:

Far from materialism being “always deployed against form” [as Jackson claims], materialism is instead the thesis that matter is always structured matter.  If materialism is deployed against anything, it would be against the schema offered by Plato in the Timeaus where it is suggested that, on the one hand, there is a formless material chora, and on the other hand a domain of idealincorporeal forms, and that a demiurge is required to mold this formless matter into formed matter.  What materialism contests is the incorporeality of form and the formlessness of materiality, instead arguing that all matter is structured matter.

Jackson describes the second type of materialism as that which posits an infinitely differentiating pulsation of formless energy at the base of all things. Whitehead’s ultimate principle of Creativity could easily be described this way. He suggests in Adventures of Ideas that Creativity is an adaptation of Plato’s “dark and difficult” concept of the Chora, or Receptacle. Plato describes the Receptacle as formless, but this is hardly the end of the story. The Receptacle is not simply the passive material from which a cosmos will be shaped, but the place within which the cosmos will come to be. Further, it is hardly “passive” at all, since it is abuzz with errant forces winnowing this way and that, grouping trace elements (pre-formed matter?) by their kind like a cosmogenic sieve, only to ceaselessly disturb every attempt at settled placement. When approaching Plato’s Receptacle, Bryant seems to fixate on one descriptor, “formless,” while ignoring the numerous indications in Timaeus that there is more to this choric “matter” than meets the eye. There’s no doubt Plato’s story could use some tweaking given our modern understanding. But let’s not forget he never claimed to be telling anything but a “likely story.” That is all we can hope to do today, even with our improved mathematics and increased data set.




Last night, I watched a short performance called “The Kepler Story” at the Morrison Planetarium in the California Academy of Sciences. The opening scene introduces Kepler’s essay on the crystalline forms of snowflakes. Kepler played with an ingenious pun between the Latin word “nix,” meaning snowflake, and the German word of the same spelling, meaning “nothing.” Is form really “nothing” at all? Kepler didn’t think so. He wondered why all snowflakes have six-sides, despite the fact that each one achieved its six-sidedness in a unique way. He searched for the “formative principle” of snow crystals. He considered the way water vapor evaporates due to heat. He considered the influence of impurities in the clouds where crystals grow.

“There must be a cause why snow has the shape of a six-cornered starlet,” Kepler wrote in his essay, De nive sexangula: “It cannot be chance. Why always six?” His answer: Hexagonal packing provides the tightest possible arrangement of water droplets. Matter has some intrinsic tendency to organize itself, taking great care to achieve geometrical harmony. Kepler’s conjecture only came to be proven basically correct several years ago. As far as Kepler was concerned, the “formative principle” at play giving shape to the water vapor had no purpose whatsoever. From his perspective, nature is “in the habit of playing with the passing moment.” Its reasons for taking shape are purely aesthetic.

The Sunset of Materialism: Whitehead’s Philosophy of Science

“The sun rose on the flawless brimming sea into a sky all brazen–all one brightening for gods immortal and for mortal men on plow lands kind with grain.” -Homer25

“God invented sight and gave it to us so that we might observe the orbits of intelligence in the universe and apply them to the revolutions of our own understanding.” -Plato26

“When you understand all about the sun and all about the atmosphere and all about the rotation of the earth, you may still miss the radiance of the sunset.” -Whitehead27

For ancient poets like Homer, the sun was a being of tremendous spiritual significance. The immense beauty of its rising and setting brought forth a dramatic display of the abiding moral harmony underlying the cosmos. For ancient philosophers like Plato, the sun was similarly a sign of the highest Good, but its visible light was thought to be only partially responsible for the shower of colors drenching earth and sky. Participating in the sunlit phenomena of the outer world was an inner noumenal light emanating from the eyes. Plato suggested that this inner light flows gently outward through the eyes from a psychic fire kindred to that animating the sun. It meets and coalesces with the light of the sun (or at night, the moon and stars) to bring forth the beauty and splendor of the universe.28 Plato’s was a participatory account of our knowledge of nature, such that soul and world were understood to synergetically intermingle in each act of perception. He considered the eyes the noblest of the senses, “source of supreme benefit to us,”

in that none of our present statements about the universe could ever have been made if we had never seen any stars, sun, or heaven. As it is, however, our ability to see the periods of [the heavens] has lead to the invention of number, and has given us the idea of time and opened the path to inquiry into the nature of the universe.29

Not only was Plato’s cosmology inclusive of perceptual experiences in its definition of nature, it felt divine eros and saw eternal eidos at work throughout the cosmos. The circling stars, sun, and moon were considered to be living gods, humanity’s wisest teachers. In his survey of European history, Whitehead places Plato at the center of the first great period of intellectual development, a period with deep influences on all subsequent thought.30 In the main, Plato’s cosmological scheme and account of visual perception, as articulated most profoundly in the dialogue Timaeus, reigned among Europe’s intelligentsia for more than 1,500 years.31 It was not until the height of the scientific revolution in the 17th century that his participatory premises were rejected by the next wave of great geniuses.

“In the year 1500,” writes Whitehead, “Europe knew less than Archimedes who died in the year 212 BCE.”32 The commonsense assumption of a person living in 1500 was that earth stood stationary at the center of a sacred series of eternally circling heavenly hosts. Below the moon, four elements composed everything; above it, something far subtler was thought to be at work. “Yet in the year 1700,” continues Whitehead, “Newton’s Principia had been written and the world was well started on the modern epoch.”33 The new analytic methods of Descartes, Galileo, and Newton succeeded in breaking the bond between the numinosity of the soul and the phenomenality of the world, bifurcating nature into two distinct substances, the material and the mental. Humanity’s understanding of its relationship with the universe underwent a fundamental transformation.

Three hundred years later, despite the evidences of modern physical science, the average 21st century person still unhesitatingly refers to the setting of the sun, to the red hues of its surrounding sky, and to the waning of its warmth as it sinks beneath the horizon. From the perspective of the well-trained mathematical physicist, such a person’s commonsense is mistaken: the sun does not set, nor is it warm, nor is its ambiance red. Its sinking, like its warmth and color, are only subjective appearances, artifacts of our perception and not facts of nature. “If the living creature were removed,” argued Galileo, the first to formalize nature’s bifurcation in terms of primary physical and secondary psychical characteristics, “all these qualities would be wiped away and annihilated.”34 The warmth and hue of a sunset, continues Galileo, “are no more than mere names so far as the object in which we locate them are concerned.”35 They reside not in the essential nature of the cosmos, but in the arbitrary names of consciousness. Plato’s insight into the erotic coupling of inner/spiritual light with outer/physical light has been degraded into the dualistic modern theory of “two natures…one the conjecture and the other the dream.”36 Scientific materialism, in other words, has come to oppose our personal experience of nature (the dream) to an abstract model of nature theorized to be the impersonal cause of that experience (the conjecture).

Following upon Galileo’s initial bifurcation of nature, Descartes brilliantly articulated the ontological and epistemological underpinnings of modern scientific materialism. The eclipse of the illusory geocentric cosmos by the mathematical elegance of Copernicus’ heliocentric model (as improved upon by Kepler) made it clear to Descartes that sensory perception could not be trusted for scientific purposes. Science was to become the study of the mechanisms of the extended things (res extensa) of nature, a study guided by the exact mathematical measurement of primary qualities like length, width, height, mass, and motion. Religion, on the other hand, was to retain responsibility for shaping the unearthly substance of the soul, providing moral guidance for existentially troubled thinking things (res cogitans) like us. Secondary qualities like color, sound, and taste were left to the free play of artists to be combined and recombined for the purpose of heightening the pleasure of appearances, rather than penetrating deeper into the archetypal dimensions of reality.37

In the intervening years since the scientific revolution, a new civilization guided by the ideals of the Enlightenment has taken root on every continent. By 1850, the values of industrial capitalism, justified by the mechanistic cosmology of scientific materialism, had infected much of the Western world, forever altering traditional forms of agriculture, manufacturing, transportation, communication, and religious practice. “[All] thought concerned with social organization,” writes Whitehead,

expressed itself in terms of material things and of capital. Ultimate values were excluded. They were politely bowed to, and then handed over to the clergy to be kept for Sundays. A creed of competitive business morality was evolved…entirely devoid of consideration for the value of…life. The workmen were conceived as mere hands, drawn from the pool of labor. To God’s question, men gave the answer of Cain– “Am I my brother’s keeper?”; and they incurred Cain’s guilt.38

Today, at the peak (if not the beginning of the decline) of humanity’s technoscientific mastery over nature, a coherent cosmology capable of guiding the adventure of civilization safely into the next millennium is just beginning to take root. Still, our knowledge remains fragmented, our society teetering on the brink of self- and world-destruction. What seemed like the cure for all ignorance in the 17th century has since become a curse. Our technoscientific way of knowing–constructed on the metaphysical assumption of the bifurcation of subject and object, fact and value, meaning and matter–threatens the continued existence of the community of life on earth.

Beginning in the early 1920s, Whitehead interrogated modern science and industrialism, not to dismiss them,39 but to remind them of what they had dismissed. He asks: “What has happened to us?” According to Stengers, this question is not an attempt to condemn scientific materialism for the wayward course of civilization, but is rather

a resource for telling our stories in another way, in a way that situates us otherwise–not as defined by the past, but as able, perhaps, to inherit from it another way.40

Whitehead’s creative retrieval of the history of natural philosophy is organized around a new concept of nature and a novel way of framing the activity of science. Instead of construing the task of science to be that of overcoming subjective illusion in order to reach objective reality, as many modern thinkers have done, Whitehead takes the speculative risk of defining nature otherwise: nature becomes, quite simply, “what we are aware of in perception.”41 “Everything perceived is in nature,” says Whitehead, “We may not pick and choose.”42 This reframing of science’s understanding of nature cannot be judged as “true” or “false” a priori; to judge it fairly, we must first trust it enough to take the “leap of the imagination”43 it implies, waiting eagerly to see in what way it transforms experience. Passing judgment on the veracity of Whitehead’s new concept of nature requires first deploying it, experimenting with its effects in the world, establishing its relevance to the values of actual life. Materialist enemies of his philosophy tend to lack the negative capability44 required to pursue the consequences of Whitehead’s unbifurcated image of the universe; they refuse to pay attention to what Whitehead’s concepts make important. Instead, they remain bound within the limits of the same old poorly composed problems (e.g., “how does the brain secrete consciousness?”, or “what sort of thing is curved space-time?”). Whitehead’s cosmology and philosophy of science require the invention and deployment of novel concepts of space, time, causality, and consciousness. These concepts pose new problems for science, allowing it to become attentive to the relevance of both quantitative patterns and qualitative perceptions in the passage of nature, releasing it from the irrational and polemical desire to replace concrete experience with abstract explanation. In this sense, Whitehead’s scientific method can be compared with Goethe’s “gentle empiricism,” which similarly rejected mechanical explanations, instead pursuing nature’s reasons by learning to participate more fully in the archetypal patterns interwoven with experience itself.45 “The divergence of [scientific] formulae about nature from the appearance of nature,” argues Whitehead, “has robbed the formulae of any explanatory character.”46

Equipped with a new kind of science, we can ask again, “What has happened to us?” We must be sensitive to both what Whitehead’s concept of nature discloses and what it makes recede into shadow. In what way does it transform the adventures of science and civilization? What becomes important when the task of natural philosophy is not to explain away value, meaning, and subjectivity at all costs, but rather to avoid the bifurcation of nature at all costs? Whitehead’s new concept of nature, should we commit ourselves to it, implies that

the red glow of the sunset should be as much part of nature as are the molecules and electric waves by which men of science would explain the phenomenon.47

Whitehead’s reframing of the task of science together with his redefinition of nature should not be construed as the imposition of limitations upon scientific knowledge. His aim is not to restrict what science can know, but to remind science what it already knows, and what its knowledge presupposes. By defining nature as “what we are aware of in perception,” Whitehead explicitly brackets “mind” (i.e., “that which perceives”) from nature. This bracketing is done in order to avoid struggling to answer badly formulated problems, such as the so-called “hard problem” of how the brain produces the mind. Posing such a problem immediately drags science into metaphysics, into reflection upon “both what is perceived and what perceives.”48 Metaphysics seeks after the nature of nature beyond what we are aware of in perception, and so pursuing such questions would negate the speculative wager whose consequences for experience Whitehead’s philosophy of science is trying to spell out. For now, says Whitehead, “we leave to metaphysics the synthesis of the knower and the known.”49 Later in his philosophical career, when he turns to full blown cosmological speculation, Whitehead will be forced to tackle such metaphysical issues; but in his early philosophy of science, he keeps his eye on the prize: a coherent foundation for our scientific knowledge of nature. From Whitehead’s re-imagined point of view, the questions of science “do not enable [it] to formulate the problem of the ‘mind’ because these questions and their answers presuppose it.”50 Science is a way of knowing nature; therefore, the pursuit of knowledge of nature presupposes that there is a knower, i.e., a mind.

Knowledge is ultimate. There can be no explanation of the “why” of knowledge; we can only describe the “what” of knowledge.51

If science is going to commit itself to the pursuit of knowledge of nature, there can be no going behind knowledge to explain it by some more fundamental activity (e.g., neurochemistry). The possibility of scientific explanation cannot itself be scientifically explained. Whitehead’s decision to bracket mind from what we are aware of in perception is not the same as the materialist’s decision to bifurcate nature into primary (physical-scientific) and secondary (psychological-aesthetic) qualities. Instead of turning science against commonsense experience through “heroic feats of explaining away,”52 Whitehead defines the truth of science in terms of its experimental achievements and experiential disclosures.53 The numinous glow of the sunset as experienced by the poet comes again to be rooted in nature, no less an aspect of what we come to be aware of in perception than the wavelengths of the photons detected by the sophisticated instrumentation of the physicist. The data of science, no matter how abstract and seemingly removed from everyday experience, must ultimately be translatable back into some operational technique or direct observation. “If the abstractions [of science] are well-founded,” says Whitehead,

that is to say, if they do not abstract from everything that is important in experience, the scientific thought which confines itself to these abstractions will arrive at a variety of important truths relating to our experience of nature.54

The “photon,” for example, is not just an invention of the physicist, nor is it simply a fact of nature. The photon is what the physicist has come to be aware of in his or her perception of light as a result of certain replicable experiments, laboratory technologies, theoretical images, and mathematical equations. The photon, as a scientific-object, is said to be abstract only in that it cannot be grasped in isolation from the “whole structure of events” or “field of activity” (i.e., the creative advance of nature) to which it belongs and through which it endures.55 From the perspective of Whitehead’s philosophy of science, the abstract will never be able to offer a satisfactory explanation for the concrete.56 The wavelength of a photon does not explain the perception of redness, nor does even a connectionist model of neurochemistry explain the artist’s aesthetic encounter with a beautiful sunset. Whenever scientific materialists try to provide such heroic explanations, they succeed only in offering descriptive commentaries in terms of the scientific objects most fashionable in their time–commentaries that presuppose the very thing they pretend to have explained away: consciousness. The only valid method of explanation from Whitehead’s point of view is the reverse of the materialist’s, an explanation which traces the genesis of abstractions back to the concrete consciousness and perceptual presences from which they emerged.57 A science that seeks to explain the concrete by way of the abstract all too easily falls prey to a form of knowledge production whose adequacy is judged instrumentally, i.e., in terms of its capacity to transform and control nature, rather than ecologically, i.e., in terms of its capacity to understand and relate to nature.

Whitehead’s aim in pursuing the philosophy of science was largely in service of pragmatic experience and commonsense: he sought to leap across and straddle the fissure bifurcating nature into the facts of physical reality on the one side and the values of psychical appearance on the other.58 In order to achieve this end, he struggled to imagine a participatory mode of attending to nature–a nature no longer objectified into the inert stuff instrumentally manipulated by an alienated technoscientific mode of knowing. Instead, Whitehead sought to disclose nature to awareness as a community of relationships shaped by the social desires and individual decisions of living organisms. Organisms cannot be characterized merely by mass, extension, and velocity; they are creatures enjoying the value of their own experience, which itself is initially inherited from the feelings of others. Contrary to Galileo, Descartes, and Newton, Whitehead’s vision of the cosmos is ecological: the final real things are individual living organisms, each dependent on their relationships to others for their continued existence as themselves.

By the late 1920s, Whitehead had given up on the problems that framed his earlier inquiry into the philosophy of science in order to pursue the riskier adventure of metaphysics. “Riskier” because “the recourse to metaphysics is like throwing a match into the powder magazine. It blows up the whole arena.”59 For the later, more explicitly metaphysical Whitehead, “mind” can no longer be bracketed from a neatly delimited “nature.” The imaginative enjoyment of the poet and the intellectual reflection of the theoretician resulting from the beauty of the setting sun must themselves be understood as ingredient in the creative advance of the universe. Mind must find its foothold in the midst of things themselves, an inhabitant of nature and not its transcendental knower. In the next section, I further unpack Whitehead’s venture beyond the philosophy of science into the formidable project of constructing a coherent cosmology justifying the civilized phases of human society.

I’ve been reading Frances Yates’ Giordano Bruno and the Hermetic Tradition (1964). Part of her project is to dispel the myth that Bruno was burnt at the stake primarily for his heliocentrism and generally scientific and materialist attitude. This was certainly one of the Roman Inquisitions many accusations, but the real reasons the Church lit his public pyre were political.

…the legend that Bruno was prosecuted as a philosophical thinker, was burned for his daring views on innumerable worlds or on the movement of the earth, can no longer stand…little attention was paid to philosophical or scientific questions in the interrogation…[instead, stress was laid] on Bruno’s religious mission. (p. 355)

His religious mission was to attend to the creation of the City of the Sun on Earth, which involved practicing the Hermetic arts of magic, astrology, and what after Jung we might call active imagination. This mission also had a political dimension, leading Bruno to ally with the likes of Henry of Navarro, who was to become King Henry IV of France. Bruno saw the potential for a universal reform of the Catholic religion in France, which was fresh off King Henry’s victory against the Spanish-backed Catholic League. Many heretical thinkers in 16th century Europe with more liberal views on religion were hoping Henry would bring peace to a continent ravaged by wars of intolerance. The Catholic Church, of course, had no interest in ceding its power to such a movement. The counter-Reformation was in full force.

Yates also tells the story of Tommaso Campanella, another Hermetic Magus who followed in Bruno’s footsteps by seeking to create the City of the Sun. Campanella lead a rebellion of Dominican monks against Catholic reformers in 1599.

But what did Bruno and Campanella’s religious mission have to do with new scientific ways of thinking and with the Copernican heliocentric theory? Campanella “praises Ptolemaeus and [admires] Copernicus, although Aristarchus and Philolaus were before him (in teaching heliocentricity)” (transl. Yates, p. 372). Both geocentric and heliocentric systems are upheld as worthy of study. Bruno’s primary reasons for holding to the heliocentric perspective were not mathematical or scientific (Ptolemy’s system was still more accurate than Copernicus’ at this point), but magico-symbolic and politico-religious. The return of the heliocentric theory was read by Bruno as an omen, a sign in the sky sent from God, prophesying the coming Golden Age when Europe would be ruled by Philosopher-Magi skilled in calling the winds of justice down to earth from the heavens.

What interests me in Yates’ historical account is the way Bruno was both modern and non-modern in his Hermetic religion: modern in that he affirmed the infinite reality of the universe; non-modern in that an infinite cosmos is the necessary counter-postulate to an infinitely real God. Modern in that he saw the moral necessity of religious freedom, but non-modern in that he felt the universe (or earth-heaven continuum) must be inter-woven throughout with astral spirits and permeated by an anima mundi (or world soul). All the beings in the universe are magically linked through the soul of the world to one another, and also to the One God, who is beyond being. The One beyond being, infinite in itself, is necessarily in relation to the beings of Being. This relation takes place through a series of revelations, beginning with the heavens. God’s infinite Speech/Word is “stepped-down” into the songs of the spiraling stars and dancing planets, which Plato identified with the Cosmic Intelligence of the World Soul. This revelation of the One through and to the many continues through every individual creature of earth, which in its individuality contains in hologrammatic form the entirety of the cosmos. As an earlier Hermetic thinker, Nicholas of Cusa, had intuited, the universe, as a reflection of God, “is a sphere of which the center is everywhere and the circumference nowhere.”

Yates ends her study on Renaissance magic by asking why it was that the scientific revolution of the 17th century began when it did. She speculates that the Renaissance Hermeticist’s new attitude concerning the place of the human being in the natural world re-directed the will, such that penetrating the secrets of the universe and coming to have mastery over nature no longer seemed so far fetched.

Behind the emergence of modern science there was a new direction of the will towards the world, its marvels, and mysterious workings, a new longing and determination to understand those workings and to operate with them. (Yates, p. 448)

Compare this attitude with that of the 3rd century Church father Tertulian, who argued that those interested in the workings of nature:

persist in applying their studies to a vain purpose, since they indulge their curiosity on natural objects, which they ought rather [direct] to their Creator and Governor.

There is a vast difference between the mechanism and mathematics of thinkers like Mersenne and Descartes and the animism and magic of thinkers like Bruno, Campanella, and Robert Fludd. But the transition between the two is not as clear cut as it would seem from our modern perspective. Like Bruno, many of the supposed fathers of the scientific revolution were deeply interested in occult knowledge. On Nov. 10th, 1619, while still a young man striving to discover a new foundation for knowledge, Descartes had a series of dreams and visions that he believed came from a higher source (Yates, p. 452). He began searching for the elusive Rosicrucian order (a Hermetic society) in Germany in the hope that they might help interpret his visions of a universal science of nature. He finally gave up in 1623 and returned to Paris, though some speculate that he actually did make contact with the secret society and had been initiated into the brotherhood. Kepler was also a rather transitional figure, having studied the Corpus Hermeticum quite closely alongside his astronomical research. Then there is the importance of alchemy to Isaac Newton, which is increasingly well-known: see especially Phillip Fanning’s recent book Isaac Newton and the Transmutation of Alchemy: An Alternative View of the Scientific Revolution (2009).

Yates points out that the early mechanists attempt to distance themselves from the magicians left them with a rather embarrassing problem: if nature was all mechanics, where did the knowing mind of the scientist fit in? The problem was especially pronounced and given its clearest formulation in Descartes infamous dualism between the res cogitans and the res extensa. “This bad start of the problem of knowledge,” writes Yates, “has never been quite made up” (p. 454).

Yates goes on:

[The mechanists] may have discarded notions on mind and matter which, however strangely formulated, may be in essence less remote than their own conceptions from some of the thought of today. (p. 455)

Writing in the early 60s, she was well-aware of the paradigm shift continuing to unfold as a result of the quantum revolution:

It may be illuminating to view the scientific revolution as in two phases, the first phase consisting of an animistic universe operated by magic, the second phase of a mathematical universe operated by mechanics. An enquiry into both phases, and their interactions, may be a more fruitful line of historical approach to the problems raised by the science of today than the line which concentrates only on the seventeenth-century triumph. Is not all science a gnosis, an insight into the nature of the All, which proceeds by successive revelations? (p. 452)

Might there be room in contemporary science for the return of the anima mundi?
