In the summer of 2018, a young orca named Tahlequah Tahlequah was the name given by The Whale Museum in Friday Harbor, Washington through their Adopt-a-Whale program. Marine biologists refer to her as “J35”. gave birth in the waters off the Pacific Northwest. When her calf died within hours, she did something that captivated millions around the world. Using her rostrum and flippers, she carried her baby’s body through the ocean for seventeen days and over a thousand miles, refusing to let go. She balanced the small corpse on her head as she swam, dove to retrieve it when it slipped away, and pushed it gently through the waves while her pod waited, watched, and accompanied her in what could credibly be called a funeral procession.
The images spread rapidly across social media and news outlets. People everywhere followed her story, many moved to tears by something they recognized immediately and viscerally. They saw a mother’s love, a parent’s refusal to accept loss—an expression of mourning that felt intimately familiar despite emanating from a being whose world we can scarcely imagine. For seventeen days, millions of us shared in Tahlequah’s vigil, connecting emotionally to what she seemed to be experiencing as she pushed through the waves to the point of exhaustion.
Some commentators dismissed this response as mere anthropomorphism—we were projecting human emotions onto animal behavior, interpreting it as grief when, they argued, we had no evidence that orcas grieve as we do. Zoologist and author Jules Howard wrote:
Pedantic (and blunt) as it sounds, if you believe J35 was displaying evidence of mourning or grief, you are making a case that rests on faith not on scientific endeavour, and that makes me uncomfortable as a scientist. Jules Howard, “The ‘grieving’ orca mother? Projecting emotions on animals is a sad mistake,” The Guardian, August 14, 2018.
Other researchers who study animal behavior strongly challenged Howard’s view. As Barbara King, a biological anthropologist who has studied animal grief for years, put it:
I am as sure as I can be in a scientific framework that there’s an expression here of her sorrow. We know by now that animal joy, animal sorrow, animal fear, animal happiness, animal grief, the whole gamut exists. So these emotions don’t (just) belong to humans. Canadian Press, January 18, 2025, quoting Barbara King.
Mark Bekoff, a behavioral ecologist, put it even more directly:
There is no doubt that many animals experience rich and deep emotions. It’s not a matter of if emotions have evolved in animals but why they have evolved as they have. We must never forget that our emotions are the gifts of our ancestors, our animal kin. We have feelings and so do other animals. Mark Bekoff, “Grief, Mourning, and Broken-Hearted Animals,” Psychology Today, November 26, 2011.
These conflicting interpretations reveal something deeper than a disagreement about animal behavior—they expose fundamental differences in how we think about consciousness and how it has evolved on Earth. The facts—Tahlequah’s seventeen-day vigil, her physical exhaustion, her pod’s accompanying presence—are not in dispute. But how we interpret those facts, what we think they mean, reflects one of the most consequential questions we face:
Is rich and complex consciousness a unique evolutionary accident in Homo sapiens, or might other species have evolved forms of consciousness that are similarly rich, even if utterly alien to us? This project argues for the latter: that what we’ll call interiority—the experiential dimension, the “what it’s like to be” aspect of existence—manifests in rich and complex forms across many species.
We use “interiority” rather than “consciousness” because the term “consciousness” has become overloaded: it can variously mean the experiential aspect itself, something that beings “have,” or specific cognitive capacities like self-reflection or language. “Interiority” keeps focus on the experiential dimension—what it’s like to be a particular organism engaging with its world—while its complement, “exteriority,” refers to the physical, measurable aspects that physics describes. Both differentiate from whatever is fundamentally real, which gives rise to both aspects. This terminology aligns with all qualitative-aspect frameworks, including idealism, panpsychism, and dual-aspect monism.
We should be candid about something: neither “interiority” nor “consciousness” can be rigorously defined in non-circular terms. Every attempt either reduces the experiential to something it isn’t — neural activity, information processing, functional states — or uses synonyms that are equally undefined: awareness, experience, sentience, “what it’s like to be.” This may seem like a fatal weakness for a book that takes consciousness as its central subject. But the situation is less unusual than it appears. We cannot define electric charge in non-relational terms either — only in terms of what it does, how it behaves, its effects on other charges. All the way down, it’s relations and behaviors, never intrinsic nature. Yet we built a technological civilization on electricity without ever resolving what charge fundamentally is.
An operational understanding of electricity has proved sufficient for its extraordinary practical applications. Interiority is in a structurally similar position, though the difficulty runs deeper — because here, the thing we’re trying to define is also the thing doing the defining. That circularity is not a problem to solve, but rather a clue about what kind of phenomenon we’re dealing with. We’ll return to this question in later chapters. For now, it’s enough to recognize that proceeding without a settled definition isn’t intellectual carelessness — it’s how inquiry into fundamental phenomena actually works.
Importantly, this broad sense of interiority–what it’s like for an organism to engage with world–exists along a spectrum of depth and complexity rather than as something beings either have or lack. It’s also not limited to humans or other highly-intelligent animals: single-cell organisms respond to their environment. For higher forms of life, interiority encompasses dimensions or modes of reality we can barely imagine—the acoustic worlds of dolphins, the distributed cognition of octopuses, and many other forms of awareness utterly alien from human subjectivity.
Understanding cetacean interiority will require imagination—not as indulgence but as methodological necessity. Their neurology is so different from ours that simple extrapolation from human experience won’t work. We must imagine seriously: given these brains, these behaviors, these evolutionary histories, what might their experiential reality encompass? This is disciplined speculation, not proof—but it’s the only rigorous path available.
Rich interiority, however, is not what makes humans unique. Complex abstraction, symbolic reasoning, and systematic manipulation of matter—these are the capacities that truly distinguish us. Other animals may possess interiority as deep or deeper than ours while lacking these specific abstractive capabilities. We mistake what makes us different for what makes us better.
And there’s a deeper possibility worth considering: our extraordinary capacity for abstraction, far from being evolutionarily superior, may indeed prove to be maladaptive. Cetaceans have maintained a stable equilibrium with their environment for millions of years. But in mere millennia, Homo sapiens has pushed multiple planetary systems toward collapse—not to mention the global ecocide potential of nuclear war. Abstract reasoning provides tremendous power—but power without commensurate wisdom becomes self-destructive.
This distinction between abstraction and interiority returns us to Tahlequah. The question isn’t whether she possesses human-like cognitive capabilities—she clearly doesn’t. The question is whether beings can experience profound interiority without human-style abstraction. Can grief be deep without being conceptually articulated? Can love be real without being symbolically represented? How we answer reveals which framework we inhabit.
Most contemporary scientists and philosophers hold, at least implicitly, that human-like interiority requires human-like cognition—abstract reasoning, symbolic language, self-reflection as we experience it. By this logic, Tahlequah might feel something, but it cannot be grief as we know it, because grief requires cognitive capacities she lacks. The seventeen days become interesting behavior, not tragedy.
But another framework is possible—one with deep roots in philosophy and increasingly supported by evidence. What if interiority is fundamental rather than derivative? What if it manifests wherever evolution creates sufficient organizational complexity, taking forms suited to each species’ particular way of engaging with reality? By this logic, Tahlequah’s massive brain, her pod’s social complexity, her sustained behavior in the face of exhaustion—these aren’t puzzles requiring explanation but manifestations of rich inner life.
The difference isn’t just academic. It shapes how we understand other beings, what ethical obligations we recognize, whether Tahlequah’s seventeen days represent tragedy or merely unusual behavior. If interiority requires human-like cognition, we can observe her vigil with detached curiosity—interesting but not morally demanding. But if interiority manifests through diverse forms we barely comprehend, then what we witnessed was a conscious being experiencing loss, and our response should be different.
Many of us sense this difference viscerally, even if we struggle to articulate why. When millions watched Tahlequah push her dead calf through the waves, something in us recognized grief-as-grief, not behavior-resembling-grief. That recognition matters—it may be valid data we’ve been trained to dismiss by a worldview that treats rich interiority as uniquely human. Trusting that recognition requires a kind of knowing that contemporary science has systematically excluded: not measurement or prediction, but what phenomenologists call disciplined imagination—the ability to imaginatively inhabit another being’s reality, constrained by what we know about their neurology and behavior, evaluated by coherence rather than proof. The epistemology of disciplined imagination has deep philosophical grounding. Edmund Husserl developed phenomenological method as a rigorous means of investigating experiential reality that resists third-person description. Francisco Varela extended this into neurophenomenology—a systematic approach to integrating first-person and third-person accounts of consciousness. Thomas Nagel’s “What Is It Like to Be a Bat?” (1974) demonstrated that subjective experience poses irreducible explanatory challenges that no amount of objective data can resolve. Iain McGilchrist’s The Master and His Emissary (2009) argues that Western thought’s preference for explicit, measurable knowledge systematically excludes valid phenomenological insight. This book builds on that tradition: imagination constrained by evidence and evaluated by coherence is not speculative weakness but epistemological necessity for questions about interiority. This is not less rigorous than demanding experimental verification—for these questions, it’s the appropriate rigor.
How did we arrive at a framework that makes such recognition seem naive? What alternatives exist that take both scientific evidence and direct knowing seriously? And what follows—ethically, practically, existentially—from recognizing that interiority is widespread rather than rare, fundamental rather than derivative?
This book addresses those questions by viewing the world through a different lens than the one employed by modern science. We will consider the phenomenon of human consciousness not as an evolutionary aberration but as a fully expected outcome in a world where the experiential is fundamental and widespread. We’ll see how humans are exceptional not for the richness of our experience but rather for the power of our abstractions and technology. And we’ll consider what can be done to intentionally evolve a culture of consciousness.
On Method: Why Imagination Matters
Before we proceed, a word about how this book approaches its questions.
You’ll encounter three kinds of claims in these pages, and I’ll work to keep them distinct:
First, established science. Tahlequah carried her calf for seventeen days. Orcas have brains with extensive paralimbic structures. Cetaceans maintain complex cultural traditions. These aren’t interpretations—they’re observations.
Second, evidence-based inference. Given this neurology and these behaviors, we can reasonably infer that orcas experience rich emotional lives. This is inference, not proof—but it’s the same kind of inference we use to conclude that other humans are conscious. We accept it for people who resemble us; the question is whether we extend it to beings with radically different neurology.
Third, disciplined imagination. When I explore what cetacean interiority might actually feel like—how acoustic transparency might create different boundaries between individual and collective experience, what seventeen days of carrying a dead calf might encompass experientially—I’m engaging in speculation. But it’s speculation constrained by evidence, not fantasy.
This third category makes some readers uncomfortable. As Wittgenstein put it “Whereof one cannot speak, thereof one must be silent.“ Ludwig Wittgenstein, Tractatus Logico-Philosophicus (1921), proposition 7. Notably, Wittgenstein himself later revised this position substantially in his Philosophical Investigations, recognizing that meaning emerges through use in ’language games’ rather than through correspondence to logical certainty. Whether the later Wittgenstein would endorse disciplined imagination as practiced here is debatable—he remained deeply suspicious of metaphysical theorizing. But his own trajectory illustrates that the demand for logical proof as the sole criterion of meaningful discourse is a position even its most famous advocate found untenable. Show proof or stay silent. But the problem is we cannot prove what another being experiences. Not ever. Wittgenstein’s dictum applies to logical certainty, not to disciplined inquiry into experiential realities. If we truly stayed silent about what we cannot prove, we’d never speak of other minds at all—including human ones. The most sophisticated neuroscience imaginable will only give us correlations—neural activity associated with reported experience. The explanatory gap between third-person observation and first-person reality is not a temporary limitation awaiting better technology or a sufficiently-detailed description of neurological processes. It’s a category distinction. This is, of course, a presumption, a statement of belief that is different in conclusion but identical in type to the presumption that a sufficient, purely physical explanation of consciousness will one day be found.
So what’s our epistemological situation? How do we know what we think we know? We have detailed neuroscience about cetacean brains. We have extensive behavioral observations. We have our own experience to draw on. And we face a choice: refuse to imagine what their interiority might be like (and call that “scientific rigor”), or imagine seriously—constrained by evidence, evaluated by coherence, transparent about uncertainty.
The refusal to imagine isn’t neutral. It’s a choice to remain within human conceptual boundaries precisely when the evidence suggests those boundaries are inadequate. It privileges a particular kind of knowing (third-person measurement) while dismissing others (phenomenological interpretation, imaginative extrapolation).
This book embraces disciplined imagination as epistemologically necessary — and not only for cetacean interiority. Later, we will also apply it to explore what it might look like to develop a genuine cultural acknowledgment of the importance of consciousness and its cultivation — questions that are necessarily more speculative but no less urgent. Imagination, far from being an indulgence, is the essential tool for exploring the landscape that opens up once we’re willing to consider that it might be real. But we need to distinguish between ideas that are well-established and those that are supported more by inference and first-person knowing than by objective evidence. I’ll signal when we move into more speculative territory.
Judge this book, then, not by whether it proves that consciousness is fundamental (it doesn’t), but by whether frameworks treating it as such illuminate patterns better than the alternatives. That’s the honest standard for these very important questions.
Our story begins with understanding what we’re actually dealing with when we encounter beings like Tahlequah.
Evolution’s Other Experiment
Tahlequah is an orca, one of approximately 90 cetacean species—toothed and baleen whales that represent evolution’s only fully oceanic mammals. Many toothed-whale species (odontocetes) possess remarkably large brains: sperm whales have the largest brains on Earth, reaching about eight kilograms—roughly six times human brain mass. Orca brains weigh around five kilograms, and several other odontocete species equal or exceed humans in absolute brain size. More remarkably, they have been this way for tens of millions of years—Tahlequah’s ancestors achieved their large brains long before the earliest proto-humans walked upright. Unlike large terrestrial mammals, these lineages have remained morphologically stable, with evolutionary change expressed primarily through social organization, behavior, and culture.
Why? If interiority is merely an accidental byproduct of neural complexity, as the standard materialist story suggests, why would evolution repeatedly invest in and sustain such metabolically intensive brain tissue? What purpose does all that neural architecture serve?
A complete answer is of course complex and out of reach. But many cetaceans exhibit behaviors similar to large-brained terrestrial species. Dolphins comprehend abstract concepts like “same” and “different.” They recognize themselves in mirrors—a capacity once thought unique to humans, great apes, and elephants—and can report their own uncertainty during cognitive tasks, forms of metacognition that suggest genuine self-awareness. They understand both symbolic gestures and grammatical structure in ways that challenge our human-centric definitions of language. Orcas maintain distinct cultural traditions—different hunting techniques, vocal dialects, and social practices—transmitted across generations and never shared even with neighboring populations whose territories overlap. Sperm whales, with their enormous brains, produce complex acoustic patterns—codas—that function as cultural markers, with different clans maintaining different repertoires across ocean basins.
Researchers in a 30-year study in coastal Australia have documented alliance networks among bottlenose dolphins spanning hundreds of individuals over decades. These are not simple cooperative relationships but sophisticated, multi-tiered coalitions requiring individuals to track not just their own allies, but their allies’ allies, navigating political landscapes that shift over years.
Cetaceans are the most extreme case of a broader pattern of convergent intelligence. Cephalopods diverged from vertebrates over 500 million years ago and evolved a fundamentally different neural architecture with no central nervous system, but they demonstrate substantial experiential depth. Corvids and parrots developed remarkable cognition with distinctly different brain architectures. Elephant brains, by far the largest of terrestrial animals, evolved well before and along completely different lines than primates. Great apes have demonstrated self-awareness and even metacognitive monitoring, realizing they don’t know something.
The pattern suggests that rich sentience—subjective experience, the felt quality of being—is not a human monopoly but an outcome that evolution has realized multiple times. Large-brained cetaceans, however, appear to provide a clear illustration of this pattern. Remarkably, odontocetes have evolved along multiple, distinct lineages, independently evolving large brains and sophisticated sentience. While the last common ancestor of all living cetaceans lived around 35 million years ago, the major large-brained odontocete lineages emerged independently during the Miocene (roughly 15–8 million years ago).
The odontocetes live in a world that is fundamentally different from and possibly incomprehensible to our visual, terrestrial experience. They navigate, hunt, and communicate through sophisticated biosonar, perceiving three-dimensional acoustic imagery and interior structures invisible to sight. Their umwelt—the subjective world they experience—is so radically different from ours that fully accessing their interiority may be impossible.
We know enough to recognize that the odontocetes’ umwelt, what neurobiologist Harry Jerison called species-specific reality, is primarily acoustic—creating a perceptual world shared among all individuals within acoustic range. Jerison expanded on this idea with a profound possibility: that odontocetes might simultaneously experience both individual selfhood and a collective awareness shared across the group—a form of interiority as alien to our experience as echolocation itself. Jerison, H. J. (1986). “The Perceptual Worlds of Dolphins.” In R. J. Schusterman, J. A. Thomas, & F. G. Wood (Eds.), Dolphin Cognition and Behavior: Comparative Research (pp. 141-166). Hillsdale, NJ: Erlbaum.
These beings—stable across millions of years, possessing brains as large or larger than ours, demonstrating sophisticated social and cognitive abilities—may have developed forms of awareness as deep and meaningful as ours, organized by completely different principles. We cannot directly access cetacean interiority any more than we can access other human minds. We infer human interiority from neural complexity and behavioral sophistication—evidence that applies equally, often more strongly, to cetaceans. The burden falls on skeptics to explain why this inference should fail for beings with larger brains and longer evolutionary histories. They may be our sentient equals, with comparable richness and depth of interior experience, albeit realized through neural architectures fundamentally different from ours.
Industrial civilization has been devastating for these remarkable beings. Millions of whales were slaughtered for their oil over the past few centuries—for lighting streets and homes prior to electrical power, and later to lubricate high-performance motors and machinery. We literally rendered down the bodies of highly sentient beings to grease the gears of our industrial machines. Populations of many species were reduced to just a few percent of their historic levels. Several may yet go extinct; others will take centuries to recover.
What This Reveals About Human Progress
Understanding what cetaceans represent fundamentally reframes debates about interiority—and opens the door for a far broader conception of interiority as an inherent aspect of reality.
Historically, humans understood the world as a living whole, investigated through multiple modes of knowing—empirical observation, contemplative practice, phenomenological insight, mythological understanding. Different wisdom traditions—from indigenous cosmologies to Buddhist phenomenology to Christian theology—developed sophisticated frameworks for understanding interiority, meaning, and right relationship. Over the last few centuries, however, Western civilization became driven by a singular imperative: to explain the world in terms the human mind can comprehend—to build models and theories that make reality intelligible, not merely predictable. That integrated vision gave way to a mechanistic metaphor described exclusively through mathematics—a deliberate strategy to make the universe graspable and controllable. This shift enabled unprecedented power to predict and manipulate matter—genuine achievements we must acknowledge and preserve. But it also fragmented our understanding, reducing interiority to epiphenomenon, meaning to illusion, and moral obligation to social construction.
We developed technological tools to serve this explanatory project—machines to help us calculate, model, and understand. But technology has diverged from that purpose. Artificial intelligence represents this divergence perfectly: it achieves breakthroughs through processes that remain opaque even to its creators. It works brilliantly without providing human-comprehensible explanations of how. The tool we built to help us understand has decoupled from understanding itself.
We’ve reached the limits of abstraction-centered progress—at least for biological intelligence. This isn’t claiming humans will never improve at mathematics or logic, but rather that machines now surpass us in these domains and the gap will only widen. The trajectory of biological consciousness developing greater abstractive capability has hit practical limits. But the limit runs deeper than machines surpassing us technologically. Explanatory abstraction itself—the attempt to make reality comprehensible through abstract models—has divorced from its original purpose. When a leading physicist defends infinite unobservable universes as “parsimonious” while dismissing consciousness-as-fundamental as metaphysical excess, something revealing has occurred—not a failure of logic, but an exposure of prior commitments about what counts as fundamental. The case is worth examining in detail. Physicist Sean Carroll defends the Many Worlds Interpretation of quantum mechanics—which postulates infinite unobservable, causally disconnected universes—because it follows from taking the Schrödinger equation as complete without ad hoc modifications. His reasoning is internally coherent. But the decision to treat the mathematical formalism as complete—as not requiring supplementation by experiential or qualitative dimensions—is itself the metaphysical commitment this essay questions. MWI is not evidence that physicalism is unreasonable. It is evidence that physicalism’s own standards of reasonableness are shaped by prior commitments about what counts as fundamental. We’ll examine this further in a later chapter. The mathematical formalism is followed wherever it leads, because the formalism is assumed to be complete. But that assumption—that mathematical description captures everything fundamental about reality—is precisely the metaphysical commitment in question, not a conclusion derived from evidence.
What remains is what we share with Tahlequah: interiority itself, the subjectivity of experience, participatory knowing that no arrangement of transistors has yet instantiated—and that, on the view developed here, no purely computational system can replicate, because interiority is not a product of computation but a fundamental aspect of reality that biological organization channels and shapes. And this reveals something profound: we’ve been over-developing one capacity while neglecting another. For centuries, we invested in abstraction and manipulation—precisely what machines now do better. We’ve barely begun cultivating experiential depth, participatory wisdom, the integration of knowledge types that only interiority enables.
We have built a global infrastructure for the manipulation of matter—schools for engineering, markets for technology, laws for property. But we have built almost no infrastructure for the cultivation of mind. We lack what philosopher Thomas Metzinger calls a Bewusstseinskultur—a genuine culture of consciousness. Because we lack this culture, we have no systematic way to value or develop the very thing that Tahlequah manifests so naturally: deep, participatory interiority.
This is where cetaceans become crucial to understanding our situation. They have mastered forms of experiential development that humans have barely begun to explore. With their large brains stable for millions of years, they appear to have reached an evolutionarily sustainable strategy—sophisticated interiority without technological manipulation, maintained across geological timescales. We cannot know what their subjective experience is like—their acoustic umwelt, their three-dimensional oceanic existence, their reality organized according to principles utterly unlike our own. But we know they demonstrate experiential depth, participatory knowing, and sustainable existence achieved without external manipulation of matter. They’ve had millions of years to refine their sense of self and, as Thomas Berry would say, their sense of place. They are an example of highly intelligent life that has learned to live in balance with their environment. They have already developed capacities we’ve barely begun to cultivate—the very capacities that become essential once abstraction reaches its limits. This represents the kind of disciplined speculation described earlier in the chapter. The behavioral and neurological evidence for cetacean cognitive sophistication is strong; the interpretation of that evidence as “experiential depth” or “participatory knowing” reflects this book’s philosophical framework rather than established scientific consensus.
Researchers in the Search for Extraterrestrial Intelligence (SETI) program have noted that technology is not the only measure of intelligence, cautioning that techno-centric bias could prevent us from recognizing highly intelligent life that never built sophisticated tools. Cetaceans may represent exactly what SETI warns about: beings who developed experiential sophistication rather than technological manipulation. They show what’s possible when evolution optimizes for participatory depth rather than abstract control.
This defines the central crisis of our time. Our civilization worships the sort of intelligence that machines now possess—the power of computation, abstraction, manipulation, and control. We are building ever-more capable machines while systematically destroying highly-intelligent beings who embody what machines can never replicate. We are obsessed with knowledge but have little regard for wisdom.
The danger is not that machines will become conscious. The danger is that we will continue to prioritize capability over wisdom, hollowing out our world until it is totally efficient, technologically advanced, and spiritually dead. Over the last several centuries we have gradually replaced the richness of interiority with the capabilities of machines, a quest for wisdom with an accumulation of knowledge. But we have failed to recognize that the capabilities machines now match—technological abstraction and manipulation—had nothing to do with moral obligation. What remains—what machines can never replicate—is interiority itself, and with it, responsibility toward other sentient beings.
This trajectory of increasingly mechanizing the cosmos is the logical outcome of human exceptionalism, a presumption that runs deep in Western thought. This presumption appears in both dominant narratives of our time: traditional theism, which places humans at the apex of divine creation, and the modern secular view, which treats interiority as an accidental byproduct of recent evolutionary history. Though grounded in opposing metaphysics, both converge on the same assumption: that human interiority—particularly our capacities for abstraction and technology—represents the pinnacle of what interiority can be.
I will argue that this assumption is wrong—or more precisely, that frameworks treating interiority as fundamental rather than derivative make better sense of the evidence. This isn’t metaphysical certainty; it’s pragmatic evaluation. Qualitative-aspect frameworks handle cetacean neuroscience, contemplative practice effects, and patterns across evolution more elegantly than physicalist reduction. They require less explanatory strain and fewer promissory notes about future discoveries.
A Recurrent View of Reality
When encounters like Tahlequah’s story unsettle modern readers, they do so against the background of a worldview that treats mind as rare, private, and biologically incidental. Yet this way of understanding reality is historically unusual. For most of human history, the universe was not imagined as a value-neutral mechanism populated by isolated observers, but as an integrated order in which experience, meaning, and structure were inseparable.
This does not mean that earlier cultures shared a unified metaphysics, nor that they possessed a concept equivalent to modern “consciousness.” They did not. Instead, they lacked the sharp division between inner mental states and outer physical reality that would later become foundational to Western thought. Perception, intention, emotion, and understanding were not confined to an interior realm; they were distributed across the entire landscape of life. The problem of how consciousness arises from matter simply did not arise, because mind and world had not yet been pulled apart.
Despite enormous cultural differences, many traditions converged on a small set of underlying assumptions: that reality is intrinsically intelligible; that knowing is continuous with the world rather than imposed upon it; that value and meaning are not merely subjective projections; and that human understanding is partial, perspectival, and situated within a larger order. These assumptions recur with sufficient regularity that historians of ideas have described them as a perennial philosophy—not a doctrine shared by all cultures, but a recurring orientation toward reality itself. And within these orientations, serious thinkers developed sophisticated accounts of the territory that physicalism would later define out of existence. The contemplative investigations of Buddhist phenomenology, the theological precision of thinkers like C.S. Lewis and David Bentley Hart, the experiential cartography of Sufi and Zen masters—these are not pre-scientific groping toward truths that physics would eventually clarify. They represent centuries of disciplined engagement with aspects of reality that our dominant framework has simply refused to investigate.
The rise of modern science brought extraordinary gains by deliberately setting these assumptions aside. In prioritizing mathematical description and predictive control, early modern thinkers bracketed qualities that resisted quantification: purpose, meaning, and lived experience. Over time, this methodological decision hardened into an ontological one. The universe came to be understood as fundamentally mindless, with awareness reclassified as a late and puzzling byproduct of physical processes.
What is striking is that many contemporary philosophical responses to this tension—idealism, panpsychism, and various forms of dual-aspect monism—arrive at positions that closely resemble the older structural intuitions, despite emerging from entirely different intellectual pressures. They do not revive ancient cosmologies, but they reopen a question that earlier worldviews never closed: whether mind belongs to reality as deeply as matter does. We’ll examine this in Part III when we explore how contemporary philosophy reconnects with perennial insights . For now, it is enough to note that frameworks of a unified cosmos have been a common theme in human history.
This project explores ideas about the fundamental nature of experiential interiority primarily through a modified lens of Western conceptions and frameworks. It recognizes the importance of scientific findings and balanced skepticism in seeking a more complete accounting of consciousness, but argues that a complete accounting cannot be achieved entirely through the current, physics-based methods of science–that the irreducible properties of the universe include non-physical aspects.
Intellectual honesty requires acknowledging uncertainty: perhaps some future physics will explain how experiential interiority emerges from purely physical processes. But this isn’t current science—it’s a promissory note. And honesty also requires acknowledging that qualitative-inclusive frameworks carry their own promissory notes—they have not yet fully explained how differentiation from the psychophysical ground produces specific experiential qualities, or why interiority takes the particular forms it does. Both sides have explanatory gaps.
But these gaps are not symmetrically situated, and pretending otherwise obscures something important. Physicalism does not present itself as one framework among others. It functions as the default assumption of virtually every Western scientific and educational institution—so deeply embedded that it operates not as a hypothesis but as the background against which all other claims are evaluated. A framework that claims this kind of authority bears a correspondingly greater burden when it fails to account for the most immediate datum any of us possesses: the fact of our own experience. Physicalism has had four centuries of institutional support, billions in research funding, and the collective effort of some of history’s finest minds—and it still cannot explain why anything feels like anything. The qualitative-inclusive frameworks explored in this book haven’t yet explained everything either, but they’ve had a fraction of the attention and resources. Given this disparity, which framework’s gaps seem more telling?
This is not a rhetorical trick. It’s a recognition that the burden of proof falls more heavily on the framework claiming to be the complete account of reality than on frameworks arguing for a hearing. Qualitative-aspect frameworks handle the pattern now—not by explaining everything, but by making interiority’s manifestation across diverse species less surprising, more naturally intelligible. They trade one kind of simplicity (everything is physical) for another (mind and matter are aspectual from the start). Whether that’s ’true’ metaphysically, we cannot know. But we can evaluate which framework illuminates more with less explanatory strain.
In the meantime, many scientists and philosophers are distancing themselves from the idea of a purely physical accounting and beginning to explore alternative frameworks. Idealism, panpsychism, and various forms of neutral monism are increasingly considered as plausible if not preferable narratives for accommodating consciousness.
This book does two things, related but distinct. First, it examines whether the physicalist framework deserves its default status—and concludes that it doesn’t. The evidence from cetacean neuroscience, contemplative practice, mind-body phenomena, and convergent evolution across species puts serious pressure on physicalism’s core assumptions, and intellectual honesty requires acknowledging this. Second, it surveys what becomes available once physicalism no longer monopolizes the space—and finds that the territory is not empty. It has been extensively explored by serious thinkers across cultures and centuries, from the contemplative traditions of Buddhism and Sufism to the theological rigor of Christian philosophers to contemporary frameworks in philosophy of mind.
These traditions don’t agree on metaphysical details, but they converge on something essential: that interiority is fundamental rather than accidental, and that this recognition has profound consequences for how we live. Escaping the gravitational field of physicalism is necessary, but insufficient. “There is so much we have yet to understand” is accurate but leaves one adrift—vaguely liberated but without orientation. The traditions that have long treated interiority as fundamental offer something more: developed accounts of what that territory looks like from the inside, tested across centuries of practice.
This project explores the fundamental nature of interiority not merely as a theoretical exercise, but as a necessary step toward a new kind of human project. The question isn’t just “What is consciousness?” but “What would it mean to take interiority as seriously as we’ve taken matter?” We have spent centuries perfecting a culture of abstraction. It is now time to build a culture of consciousness.
A culture of consciousness is not a return to pre-scientific mythology. It is a systematic, evidence-based commitment to cultivating valuable states of mind—states defined by intellectual honesty, the reduction of suffering, and the recognition of interiority in other beings. It is the decision to foster mental autonomy with the same rigor we currently apply to building machines.
The burden of wisdom falls exclusively on us. Cetaceans have maintained their equilibrium for millions of years. We have not. Despite our unique combination of abstract reasoning and planetary power, we are in the midst of a self-inflicted crisis that threatens the very systems that sustain us. We must now choose. We can continue to let our tools outpace our wisdom, or we can begin the work of matching our external power with an equal depth of interior life—reclaiming not just our balance with the world, but our dignity as a species.
This book is an invitation to that work.
