Before examining how consciousness manifests across species, we need to acknowledge that many of the terms we are using do not have an historical precedent. Terms like “psychophysical continuum,” “manifestation,” and “differentiation” sound strange not because the concepts are confused but because four centuries of mechanistic thinking shaped our vocabulary. We’re trying to describe participatory wholeness using language built for mechanical parts.
You’ve probably experienced this difficulty yourself — trying to articulate moments of recognizing consciousness in another being, or why the mechanistic account feels inadequate, and finding that ordinary language fails. The words sound either too mystical or too vague. This isn’t your failure; it’s a limitation of our language.
The problem runs deeper than you might expect. We cannot adequately define even the most basic terms. What is “matter”? Physics describes its structure, relations, and behavior with extraordinary precision — Russell’s “causal skeleton of the world” — but remains silent about its intrinsic nature. Although we know with certainty that matter exists, we cannot say what it is, only what it does. “Fundamental particle” reduces to what? Describes what? The question “what is matter?” hits language limits before it reaches conceptual ones.
The definitional problem of “consciousness” is even more acute. Any definition proves circular. “What it’s like from inside” presumes consciousness to understand the definition. “Subjective experience” defines one mystery with another. “Phenomenal awareness” uses synonyms without explaining. The hard problem is partly a language problem: we’re trying to describe from outside what only exists from inside, like asking what red looks like using only words. Some even say that because we cannot define it, consciousness doesn’t really exist. As Daniel Dennett argues in “Consciousness Defined.”
Even the terminology for continuum frameworks is imperfect. We use “psycho-” (mental) and “-physical” to describe something supposedly prior to that distinction. The word “continuum” suggests a line with poles, but that spatial metaphor may itself distort. We use this terminology as the least problematic available, not because it perfectly captures what we mean.
The problem can be compounded by the structure of English grammar itself. Subject-verb-object construction embeds a particular metaphysics: things (nouns) that do actions (verbs) to other things (objects). This structure makes it nearly impossible to discuss consciousness without treating it as either a thing that exists, a process that happens, or a property that things have. But what if consciousness is none of these? What if, as continuum frameworks suggest, both mental and physical features differentiate from something that the subject-object grammar simply cannot express? Our fundamental grammatical categories themselves may foreclose certain possibilities.
This grammatical constraint is not universal. In Chinese, 心 (xīn) — often translated as “heart-mind” — functions as both noun and verb, allowing more fluid expression of consciousness as activity rather than substance. This linguistic integration of emotion and cognition isn’t merely philosophical preference — it may better capture biological reality. As we’ll explore in Chapter 5, cetacean brains display massive development of the paralimbic system — the architecture processing emotion — deeply integrated with cognitive functions in ways that challenge Western assumptions that advanced intelligence requires emotional suppression. The Chinese language that refuses to separate 心 (heart-mind) and Indigenous frameworks that treat consciousness relationally may recognize what Western categories systematically obscure: that feeling and thinking aren’t opposed but aspects of integrated awareness.
Indigenous languages often structure reality in ways that naturally accommodate relational ontology. The Blackfoot language, as physicist F. David Peat documented in Blackfoot Physics, structures reality primarily through verbs rather than nouns, enabling speakers to express ongoing processes and relationships more readily than English allows. Botanist Robin Wall Kimmerer describes in Braiding Sweetgrass how Potawatomi employs what she calls a “grammar of animacy” — linguistic structures that distinguish beings by whether they demonstrate agency and reciprocity rather than by arbitrary human categories. In English, we grammatically equate a living orca with a rock, both rendered as “it.” Potawatomi grammar makes such conflation structurally impossible.
This reflects deeper epistemological differences. As Tewa scholar Gregory Cajete argues in Native Science, Indigenous knowledge systems integrate empirical observation with relational participation rather than treating them as opposed. What Western frameworks dismiss as “anthropomorphism” — projecting human qualities onto nature — Indigenous epistemologies recognize as accurate perception: beings do have intentions, relationships matter causally, consciousness manifests throughout the living world. The difficulty isn’t that Indigenous peoples are less rigorous; it’s that their conceptual frameworks never underwent the mechanistic turn that separated mind from matter.
Vine Deloria Jr., in God Is Red, and contemporary philosopher Kyle Powys Whyte demonstrate that Indigenous ontologies engage Western philosophy and science rigorously while maintaining commitments that continuum frameworks echo: reality constituted by relationships rather than isolated substances, multiple valid ways of knowing, consciousness as fundamental rather than derivative. These aren’t romantic appeals to “ancient wisdom” but recognition that when multiple independent intellectual traditions converge on treating consciousness as relational and participatory, the outlier may be the mechanistic framework that dismisses them all.
We’ll explore these convergences more systematically in Chapter 7. For now, the point is simpler: the difficulty articulating continuum frameworks in English reflects specific Western categorical choices, not universal cognitive limits. Other traditions that never reified the mind-matter split don’t struggle to overcome it.
Different metaphors enable different insights. Indigenous “grammar of animacy” makes consciousness-recognition structurally natural. Eastern non-duality frameworks express what Western thought requires mathematical analogies to grasp. These aren’t merely different ways of saying the same thing — they’re different modes of engagement with reality that make certain recognitions easier or harder.
As philosopher Anthony O’Hear has observed, language is not just a “reading-off” of reality but actively shapes the picture we have of the world and our place within it. Anthony O’Hear, “Beyond Evolution”, p. 39 We are not discovering labels for pre-existing categories; we are creating categories through the act of labeling. And once created, those categories constrain what we can think — often below our conscious awareness.
Consciousness and Conscience: A Revealing Split
“Consciousness” and “conscience” were historically the same word — and in some languages, still are. This is a conceptual fossil revealing a major shift in how we understand the mind.
In Latin, conscientia meant “knowing together” (con-scire) — a knowing that witnesses itself, often understood as sharing knowledge with oneself or, in religious contexts, with God. The term carried inherent moral weight: to be conscious was to be accountable to what one knows. When medieval philosophers used conscientia, they didn’t distinguish between awareness and moral sensitivity because the distinction seemed artificial. To know something was already to stand in evaluative relationship to it.
French preserved this unity. Conscience still covers both meanings — awareness and moral sense — requiring context to distinguish them. The language never forced the split.
English did split them, though the process took centuries. As late as the 17th century, “conscience” still meant both moral awareness and general consciousness. But the mechanistic turn required a neutral term for studying mind as mere object rather than moral witness. “Consciousness” emerged as the technical, psychological term stripped of moral connotations — pure awareness, supposedly value-free.
German manufactured an even more deliberate separation. Christian Wolff and 18th-century German philosophers coined Bewusstsein (consciousness) as a technical term explicitly distinct from Gewissen (conscience), though both share the root wissen (to know). Thomas Metzinger observes that this linguistic engineering wasn’t accidental — it reflected and reinforced the new mechanistic view that treated awareness as neutral observation rather than engaged participation. Metzinger, T. (2020). The Elephant and the Blind: The Experience of Pure Consciousness. MIT Press. Epilogue on Bewusstseinskultur discusses the consciousness/conscience connection and its implications for mental autonomy.
As C.S. Lewis documented in Studies in Words, the Latin conscientia originally meant “acting as a witness to oneself” — both perceiving and being accountable for what one perceives. The word gradually lost its moral weight in English through the desire to study mind as neutral object rather than moral agent. Lewis, C.S. (1960). Studies in Words. Cambridge University Press. Chapter on “Conscience and Conscious” traces the historical split and its philosophical implications. John Locke formalized this split in his 1690 Essay Concerning Human Understanding, appropriating “consciousness” to define personal identity based on memory while stripping away the “moral witness” aspect that conscientia had always carried. Locke, J. (1690/1975). An Essay Concerning Human Understanding. Ed. Peter H. Nidditch. Oxford: Clarendon Press. Book II, Chapter XXVII introduces “consciousness” as technical term for personal identity.
Owen Barfield, examining language evolution in History in English Words, argued that early human languages didn’t distinguish sharply between inner and outer, fact and value, subject and object. He viewed the conscience/consciousness split as symptomatic of what he called the shift from “original participation” to “onlooker consciousness” — the detached, scientific mode that treats awareness as passive observation rather than engaged relationship. Barfield, O. (1926/1967). History in English Words. London: Faber and Faber. Discusses shift from “original participation” to “onlooker consciousness” reflected in language evolution.
This matters for understanding consciousness cultivation across traditions. What contemplative practices develop isn’t merely “awareness” in the modern, neutered sense — a neutral registering of stimuli. They cultivate something richer: what Metzinger calls “mental autonomy,“ Metzinger, T. (2020). The Elephant and the Blind: The Experience of Pure Consciousness. MIT Press. Epilogue on Bewusstseinskultur discusses the consciousness/conscience connection and its implications for mental autonomy. what virtue ethics calls practical wisdom, what Buddhist traditions call clarity and compassion arising together, what Indigenous frameworks recognize as right relationship. The practices aim at integrated development of awareness and responsibility, perception and care, consciousness and conscience.
The difficulty reintegrating these concepts may reveal not their true separateness but our conceptual impoverishment. If to become more conscious is inherently to become more conscientious — if awareness and moral sensitivity are aspects of unified capacity rather than separate faculties — then the mechanistic framework that requires their separation faces a deeper problem than it acknowledges.
Contemporary cognitive science is recovering what the linguistic history suggests. Francisco Varela and Evan Thompson’s “enactive” approach argues that mind is never a neutral mirror but is inherently caring and value-laden. Thompson, E. (2007). Mind in Life: Biology, Phenomenology, and the Sciences of Mind. Harvard University Press. Develops enactive framework showing consciousness as inherently value-laden and concerned. To be conscious is to be an organism concerned with survival, meaning, relationship — awareness is always already evaluating, never truly neutral.
The language shapes what we think is possible. A framework that forces us to explain conscience as either cultural overlay or evolutionary add-on to supposedly neutral consciousness starts from a split that may itself be the problem. Indigenous languages that never made this separation, contemplative traditions that cultivate consciousness and conscience together, even the original Latin conscientia — all suggest that the unity may be more fundamental than the mechanistically-motivated split.
When we discuss consciousness cultivation in later chapters, remember that we’re talking about something closer to the original conscientia: awareness that knows itself, cares about what it knows, and takes responsibility for that knowing. Not consciousness or conscience, but consciousness as conscience — awareness that is inherently, not accidentally, moral.
Flatland and the Limits of Conceptual Machinery
While Indigenous languages preserve relational ontologies grammatically, Eastern frameworks express non-duality philosophically, and the Latin conscientia united awareness with moral sensitivity linguistically, Western thought after the mechanistic turn has often required mathematical analogies to grasp what these traditions handled naturally. Edwin Abbott’s 1884 novella Flatland provides one such analogy — useful not because it surpasses these other traditions but because it demonstrates dimensional limits using terms familiar to readers accustomed to thinking through geometric abstraction.
Abbott imagined a two-dimensional world with beings who possess length and width but no height. For these creatures, three-dimensional space is literally inconceivable — not merely unknown, but impossible to think about using their available conceptual resources. When a sphere passes through Flatland, its inhabitants perceive only a circle that mysteriously grows and then shrinks. A three-dimensional object cannot be described with a two-dimensional vocabulary. But it’s not only the ability to describe that is lacking — it’s the capacity to imagine.
We used this analogy in Chapter 2 to illustrate how critiques of metaphysical frameworks may reflect conceptual limits rather than the frameworks’ actual deficiencies. Here the point is different: when concepts genuinely outrun our conceptual machinery, new vocabulary helps only at the margins. We may need different modes of engagement altogether. But at minimum, we need to recognize the limits of the language we’re using.
Linguists Edward Sapir and Benjamin Lee Whorf proposed that language not only reflects thought but shapes it. We do not merely describe the world in language; we perceive the world through the structures our language makes available. Benjamin Lee Whorf, Language, Thought, and Reality (1956). In Hopi, for example, time is not broken into past, present, and future in the way English demands. Instead, it is experienced as a continuum of becoming. Such differences are not just semantic — they can shape cognition, memory, and intuition. John A. Lucy, Language Diversity and Thought (Cambridge University Press, 1992).
Abbott’s parable suggests something important: when concepts genuinely outrun our conceptual machinery, new vocabulary helps only at the margins. We may need different modes of engagement altogether. But at minimum, we need to recognize the limits of the language we’re using.
A necessary caution: the Flatland analogy is powerful but epistemically dangerous if deployed asymmetrically. It’s tempting to suggest that critics of continuum frameworks are like Flatlanders unable to perceive a third dimension. But the same logic applies in reverse — proponents of these frameworks might be imagining dimensions that don’t exist, confusing the limits of current understanding with evidence of something beyond. The analogy illustrates that conceptual limits are real; it cannot tell us which direction those limits face. We should use it to cultivate humility about all our frameworks, not as a shield for any particular one.
The Quantum Precedent
The history of quantum mechanics provides a real-world case where exactly this situation arose. In the early twentieth century, physicists discovered phenomena that could not be captured in ordinary language. Electrons and photons behaved in ways that violated not only classical physics but basic assumptions embedded in our vocabulary. Werner Heisenberg observed that words like “position” and “velocity” did not carry the same meaning in the realm of atoms, as atomic “things” can be a particle and a wave at the same time. Arthur Miller, 137, p 100
The problem went deeper than ambiguity. Certain quantum mechanical concepts, Heisenberg noted, were “derivable neither from our laws of thought nor from experiment.” The very categories available in ordinary language — derived from macroscopic experience and classical physics — simply did not apply at the quantum scale.
The physicists who founded quantum mechanics were in a situation analogous to Flatlanders encountering a sphere: they could track measurable effects, but the conceptual categories available to them could not capture what they were actually observing. There was, however, a crucial difference. The physicists could conceptualize a phenomenon and describe it mathematically, even if they couldn’t visualize or describe it in ordinary language. Flatlanders could not even conceptualize a third dimension.
Our situation with consciousness and continuum frameworks more closely resembles the Flatlanders’ predicament. We’re attempting to discuss something that may outrun not just our vocabulary but our conceptual categories themselves — categories shaped by centuries of assuming matter and mind are fundamentally separate entities. Consider quantum field fluctuations, a staple of modern physics. Physicist Sean Carroll points out that this language is essentially poetic:
“Quantum fields don’t really ‘fluctuate’; that’s poetic language, employed to help us connect to our classical intuition. What fluctuates are our observations — we can look at the same field multiple times and measure different values.“ Sean Carroll. “Are Many Worlds and the Multiverse the Same Idea?” Discover, blog, May 26, 2011.
The word “fluctuates” imports classical mechanics concepts into a domain where those concepts do not properly apply. But physicists have no other words.
Niels Bohr emphasized this predicament repeatedly: “We are forced to use the language of classical physics simply because we have no other language in which to express the results.” Even when physicists knew classical concepts were inadequate, they had no alternative vocabulary for communicating their findings. But Bohr went further, making the far more radical claim that “reality” was a word we must learn to use correctly. Petersen, A., 1963, “The Philosophy of Niels Bohr”, Bulletin of the Atomic Scientists, Sep 1963, 8–14. We cannot step outside language to some neutral vantage point from which to evaluate whether our words accurately capture reality. We are always inside language, and “reality” is itself a word whose meaning we negotiate through language. The question is not whether language perfectly mirrors reality — it cannot — but how to use language responsibly given these constraints.
Quantum mechanics found a way forward through mathematical formalisms that could express relationships and structures that words could not capture. But even mathematical formalism required interpretation. The mathematics worked spectacularly for predictions, but deep disagreements emerged about what it meant. Bohr insisted we should not ask what quantum mechanics tells us about reality independent of observation. His Copenhagen Interpretation, dominant for decades, essentially declared such questions meaningless — as David Mermin famously quipped: “Shut up and calculate!“ Mermin, N. David. 1989. “What’s Wrong with This Pillow?” Physics Today 42 (4): 9–11.
Yet other physicists — Einstein, Bohm, and contemporary researchers exploring quantum foundations — insisted that understanding what the mathematics represents matters. Bohm developed his alternative interpretation precisely because he believed physics should describe reality, not just predict measurements. This tension persists: some say interpretation is philosophy, not physics; others say physics without interpretation is mere calculation.
We face a similar choice with consciousness, though our situation differs in a crucial way. Mathematical formalism won’t help us discuss continuum frameworks — these aren’t mathematical structures. But we can learn from how quantum physicists handled language limits: acknowledge the inadequacy, use terms carefully and often symbolically, and remain explicit about where language breaks down.
The Terms We’re Using
Throughout the previous chapter, we employed terminology that requires careful handling:
“Psychophysical continuum” — refers to what Pauli and Jung described as the unus mundus: a unified reality intrinsically neither mental nor physical, from which both differentiate. The spatial metaphor of “continuum” is imperfect but no better alternative exists.
“Consciousness,” “mind,” “awareness” — all defined relative to human experience. We have no neutral terms for discussing non-anthropocentric interiority. Even saying “interiority” or “experiential aspect” carries human-centric assumptions about what experience might be like.
“Fundamental” — means what it means in physics: irreducible to something more basic, not simple or fully knowable. Charge and mass are fundamental — explanations start from them rather than arrive at them.
“Matter,” “physical,” “material” — we use these as if they’re clear, but physics describes only structure and behavior, not intrinsic nature. When we say “physical aspect of the continuum,” we’re using “physical” to mean something like “exterior, relational, measurable” — but that’s already an interpretation, not a transparent description.
“Manifestation” and “differentiation” — avoid the terms “emergence” and “causation” which carry mechanistic implications. They suggest aspects becoming articulated rather than being produced from something unlike themselves.
“Decompositional” versus “compositional” — Harald Atmanspacher formalized this distinction in developing the Pauli-Jung framework, and it proves philosophically crucial: compositional approaches build consciousness from parts (facing the combination problem), while decompositional frameworks understand mental and physical as differentiating aspects of an undivided whole. Yet even these technical terms are cumbersome and metaphorical, using spatial language (“breaking apart” vs. “assembling”) that may not fit the reality they’re meant to describe.
These terms are tools, not transparent descriptions. Like quantum physics repurposing classical concepts, we use them carefully while acknowledging their limitations.
Scientific terminology itself encodes physicalist assumptions more broadly. “Tropism” rather than “response,” “mechanism” rather than “organized system,” “instinct” rather than “intelligence” — each choice predetermines what interpretations seem reasonable. This is why continuum frameworks sound strange: not because they lack rigor but because we lack vocabulary. Four centuries of mechanistic thinking is widely embedded in our language.
Working Within Constraints
We cannot escape language’s constraints, but we can work responsibly within them. The terms we use — consciousness, manifestation, psychophysical ground — are necessary tools, not perfect descriptions.
At key moments, we’ll ask for something beyond purely linguistic understanding: direct recognition of your own consciousness, intuitive grasping of why mechanistic reduction feels inadequate. This isn’t mysticism or failure of argument — it’s acknowledging that some knowing comes through participation rather than verbal description.
The risk of using unfamiliar language is real. But the greater risk is staying trapped in vocabulary that seems precise only because it’s familiar — mistaking linguistic habit for transparency to reality.
With these limitations acknowledged, we turn to the evidence. The next chapter examines how consciousness manifests across evolution, using imperfect terms carefully and asking you to recognize what words can only approximate.
