Neoplatonism is the philosophical tradition founded by Plotinus (205–270 CE), building on Plato. Its effect on how the body was conceptualized is about as consequential as any idea in Western history.
Plotinus proposed a hierarchy of reality emanating downward from “the One” — ultimate, undivided being — through Nous (divine intellect), through the World Soul, and finally into matter. Each level is less real, less good, and further from the divine than the one above it. Matter — the physical world, the body — sits at the bottom. It is characterized not as evil exactly, but as privation: the absence of the Good. Porphyry, Plotinus’s student and biographer, noted that Plotinus “seemed ashamed of being in the body.” That’s not incidental — it’s the logical conclusion of the framework.
The soul’s purpose, in this system, is to ascend back toward the One through contemplation and purification. The body is what drags it down. It generates passions, desires, appetites — all of which pull toward multiplicity and away from unity. The body is the prison the soul needs to escape.
Augustine is the transmission mechanism. He explicitly describes reading “the books of the Platonists” (almost certainly Plotinus and Porphyry in Latin translation) as a major step toward his conversion. His concepts of concupiscence — disordered bodily desire as the inherited wound of original sin — are Neoplatonic in structure: the body pulls the will downward, away from God. His enormous influence on Western theology, both Catholic and Protestant, made this framework near-universal.
The irony is that Christianity’s own core doctrines resist it. The Incarnation and bodily resurrection are explicitly body-affirming — God takes flesh, the body participates in salvation. But the Neoplatonic inheritance ran so deep in the institutional tradition that the body-denying framework persisted despite those doctrines, producing the functional dualism the essay describes.
The body’s responsibilities in this framework are entirely negative — to be subdued, disciplined, mortified. Fasting, celibacy, physical austerity become spiritual goods not because they’re healthy but because they enact the soul’s dominance over matter. The body’s signals — hunger, desire, fatigue, pleasure — become morally suspect by definition: they represent the downward pull. Attending to them carefully is the opposite of the spiritual task. Ignoring or overriding them is virtue.
Modernist Thought
The Neoplatonic inheritance was compounded by a second current arriving through an entirely different intellectual lineage: the mechanistic worldview that emerged from Descartes in the seventeenth century and accelerated through industrialization.
Descartes is the pivot. Cogito ergo sum — I think, therefore I am — places identity entirely in thought. What he missed, and what phenomenology later made explicit, is the inversion: I am, therefore I think. Embodied existence precedes and enables thought; the body is not a vehicle the thinking self operates but the condition of possibility for thought at all. Descartes didn’t discover that thinking proves existence — he assumed a disembodied thinking subject and then had to account for the body as a separate, subordinate problem. The mistake is in the starting position.
From that axiom — res cogitans (thinking substance) versus res extensa (extended substance) — he described the body as a hydraulic automaton, its movements explicable through the same principles as a clock or a mill. The body does not think, feel, or signal — it executes. This was not a scientific finding but a metaphysical prior commitment, a reductive framework within which science was subsequently practiced. The empirical tradition that followed didn’t produce this conclusion; it was conducted inside it, constrained from the outset by the assumption that what the body feels is categorically separate from what the mind knows.
Industrial modernity extended the logic into practice. The body became a unit of productive output — its capacity measured in calories, its labor quantified by Taylor’s time-and-motion studies, its failures diagnosed as component breakdowns. Factory work organized human bodies the way machines were organized: repetitive, specialized, stripped of any function beyond the task assigned. The body’s felt experience — fatigue, discomfort, the signals of sustained strain — was irrelevant to the productive calculation, noise to be managed rather than information to be read.
Modern medicine inherited and institutionalized this reductionism. The body was divided into systems, each the domain of a specialist: cardiology, neurology, gastroenterology, endocrinology. Disease became a localized malfunction — a pathogen to eliminate, a deficiency to supplement, a structural failure to repair. Treatment targeted components. What this framework systematically discarded was the body as it actually is: an integrated, dynamical, microbiological system of distributed systems in continuous bidirectional communication — the gut’s enteric nervous system producing roughly ninety to ninety-five percent of the body’s serotonin, the autonomic nervous system running continuous feedback between visceral state and brain, the immune and endocrine networks co-regulating mood, cognition, and behavior through channels that don’t respect the specialist’s boundary lines. The microbiome alone — trillions of organisms integral to immunity, digestion, and neurological function — was invisible to mechanistic medicine until recently, because the framework had no category for it.
The convergence with Neoplatonism is what matters. Two entirely different traditions — one theological, one built on a reductive axiomatic framework — arrived at the same practical conclusion: the body’s signals are not primary data. In the religious tradition, because the body is fallen and its appetites are the downward pull away from God. In the mechanistic tradition, because what the body feels is subjective noise; what counts is the measurable output. The felt signal is irrelevant in both cases. Attending carefully to what the body is communicating — developing sensitivity to its states, learning to read its responses as information — is either spiritually dangerous or epistemically naive, depending on which tradition is speaking. The outcome is identical: a culture systematically trained away from somatic attention, which is precisely the vulnerability that total ideologies exploit.
Why Did This Happen?
The instinct driving all of this is legitimate. Life contains genuine suffering and confusion, and the demand for meaning in response to that is not pathological — it’s what humans do. But meaning operates on two different levels that are easily conflated.
Causal meaning asks why something happened — what produced it, what are the mechanisms, what preceded it. This is answerable in principle through investigation. It’s the register science operates in.
Ultimate meaning asks why anything exists at all, what the point of being here is, what suffering means in the largest sense. This is not answerable by the same method. It’s the register ideology and religion operate in — and it’s where the genuine human need lives.
People arrive at the question in the second register: genuine existential weight, suffering that demands a why at the deepest level. Ideologies offer answers that blur both. They provide ultimate meaning — your suffering has cosmic purpose, history is moving toward liberation — bundled with causal claims about how the world works. The causal claims are in principle checkable. The ultimate meaning claims aren’t. But once you’ve accepted the package for the comfort of the ultimate answer, the causal claims inherit the same immunity. You’re no longer evaluating them — you’re defending them.
To know that struggle is not the totality, that there is something beneath the difficulty worth orienting toward, is important. People were not wrong to search. They got fixated on the hardest parts of life, reached for the nearest complete answer, and accepted unverifiable causal claims as the price of getting it.
The three routes available were: defer to a higher authority, escape the question entirely, or make yourself the authority. Higher authority discards the internal signal — your experience is subordinated to doctrine. Escape avoids the question. Self-as-authority, the Cartesian route, discards the external check — reason conducted in isolation, verified only by itself. All three collapse the tension between direct experience and external verification rather than holding it.
Descartes illustrates the third failure cleanly. He locked himself in a room until he found an answer, which demonstrates commitment but has nothing to do with validity. The Meditations are entirely discursive — chains of logical inference, no attention to the felt quality of experience, no phenomenological precision in the contemplative sense. He thought very hard, which is not the same as attending carefully. If he had actually meditated — directed sustained attention to experience arising in a body — he might have noticed that the thinking self is not separable from the breathing, sensing, embodied creature doing the thinking. I am, therefore I think. The cogito is partly a confirmation of his method, not just a discovery: he became attached to reasoning as the instrument, and reasoning became the conclusion. But not all knowledge comes from propositional logic.
The deeper problem is that he never doubted the doubter. The stated method of the Meditations is radical doubt — strip everything back, accept nothing unverified. The spirit of that is right. But he doubted the senses, doubted external reality, doubted other minds, while the thinking subject doing the doubting was never put in question. That was the one thing he held throughout. Which means he didn’t perform radical doubt; he performed radical doubt about everything except his own self-concept as a reasoning mind.
A genuine contemplative practice would have caught this immediately. Sit quietly, attend carefully, and what you notice is that the “I” seeming to do the thinking is itself unstable — thoughts arise without a fixed thinker behind them, the sense of self fluctuates with mood and attention and bodily state, the feeling of being a unified rational subject is a construction that comes and goes. Buddhism makes this its central observation: anatta, no fixed self. The self Descartes found at the bottom of his doubt is the very thing sustained meditation puts in question.
He went in carrying the most important preconception of all — that there is a stable, unified, rational “I” doing the thinking — and his method was designed to confirm it because it never looked directly at it. The cogito doesn’t discover the self; it assumes it and presents the assumption as a finding. Descartes tightened his grip on self-concept through sustained reasoning. Meditation loosens it through sustained attention. Same isolation, opposite movement.
What makes this failure particularly striking is that the tools for investigating experience below the level of thought had existed for nearly two thousand years before Descartes sat in his room. Buddhism built an entire epistemology around noticing. The Vipassana tradition doesn’t begin with doctrine — it begins with bare attention to sensation before naming, before interpretation, at the moment before the label arrives. The Pali word sati — usually translated as mindfulness — is closer to “noticing” or “remembering to notice.” It’s a capacity, not a belief, directed precisely at the layer Descartes never reached: awareness observing itself, sensation before it becomes concept.
Nagarjuna’s analysis of consciousness in the second to third century CE, Vasubandhu’s Abhidharma mapping of mental factors in the fourth or fifth century, the Yogacara school’s phenomenology of how experience is constructed — these are rigorous, systematic investigations of exactly the territory Descartes ignored. They didn’t have the instruments of modern neuroscience. They had something more direct: sustained attention applied to the thing itself.
Neuroscience has since confirmed what these traditions mapped — that emotion and sensory experience are prerequisites for thought, not its byproducts; that awareness precedes and contains thought rather than the reverse. But that confirmation doesn’t make the Buddhist insight newly valid. It was valid when it was first articulated. The neuroscience is secondary confirmation using a different instrument. Treating it as the primary source inverts the epistemic hierarchy: the contemplatives were doing original investigation, and they were doing it earlier and more carefully than the philosophical tradition that displaced them in the Western canon.
Descartes’ error wasn’t inevitable. Alternatives existed, were being actively practiced, and had already produced detailed maps of the territory he claimed to be discovering from scratch.
What both the theological and the mechanistic traditions missed is that external verification and phenomenological experience are not in competition — they operate in different registers and each corrects for what the other cannot catch. External verification — intersubjective checks, empirical evidence, competing testimony — corrects for the systematic errors that individual experience produces: confirmation bias, motivated reasoning, the distortions of particular emotional states. Phenomenological experience provides the primary data that any external framework is then interpreting. Discard the external check and you’re trapped inside your own narrative. Discard the internal signal and you’ve lost the thing that makes any framework meaningful in the first place.
The question was never which arbiter to trust. It was learning to hold both without collapsing into either.
