What did Aristotle mean by flourishing?
Twenty-four centuries ago, a man teaching in the shade of the Lyceum made an observation that the modern world keeps rediscovering: happiness is not a feeling. It is a function.
Aristotle called it eudaimonia. The word gets translated as "happiness" in most textbooks, which is misleading in the way that calling a cathedral a "building" is technically accurate but misses everything that matters. Eudaimonia means something closer to "operating in accordance with your full capacity." Flourishing. Not the pleasure of a good meal or the thrill of a win, but the sustained state of a human being doing what a human being is designed to do — thinking clearly, acting virtuously, creating value, contributing to the polis — and doing it well.
The crucial detail, the one most summaries leave out: Aristotle insisted that eudaimonia requires material conditions. You cannot flourish while starving. You cannot exercise practical wisdom when your body is in crisis. The life of the mind depends on the health of the body. This was not a footnote in his ethics. It was a structural requirement.
We keep returning to that structural requirement because of a number published in 2022 that we think changes the shape of the conversation.
What does 93.2% actually mean?
Araújo and colleagues at Tufts University, publishing in the Journal of the American College of Cardiology, measured cardiometabolic health across five markers: blood pressure, blood glucose, cholesterol, waist circumference, and BMI — all in healthy ranges, without medication. Of American adults, 6.8% qualified. The remaining 93.2% were suboptimal on at least one marker, and most on several.
Sit with that. Ninety-three point two percent.
This is not a statistic about disease. It is a statistic about the biological foundation Aristotle identified as prerequisite for flourishing. Nearly everyone is missing it. The "normal" American body is not a body at baseline. It is a body in some stage of metabolic compromise, operating below the threshold that a Greek philosopher twenty-four centuries ago recognized as the floor — not the ceiling — of a good life.
We have been tracking this number across our coverage, and we keep arriving at the same conclusion: the most radical act available right now is not enhancement. It is restoration. When 93.2% of the population lacks the biological foundation for flourishing, simply getting back to baseline is extraordinary.
That is what this series is about. Not transhumanism. Not biohacking fantasies. Not going beyond human. Going back to human. The full version.
Why do we keep confusing restoration with enhancement?
There is a distinction in the medical and philosophical literature between therapy and enhancement. Therapy moves you from pathological to baseline. Enhancement moves you from baseline to something beyond. The categories seem clean. They are not.
When 93.2% of the population is below baseline, therapy and enhancement collapse into the same project. Restoring someone to normal metabolic function — stable blood sugar, healthy blood pressure, controlled inflammation — is simultaneously a therapeutic intervention and an enhancement relative to the population. The person who sleeps eight hours, eats whole food, and manages their stress is not "optimized." They are functioning as designed. But measured against the 93.2%, they look superhuman.
This collapse matters because it exposes a lie buried in the word "normal." Normal is a statistical concept. It describes what is common, not what is healthy. When the common state is pathological, normalcy becomes the disease and deviation becomes the cure. We have watched, in our research and across our community, otherwise intelligent people defend habits that are destroying them because those habits are normal — because everyone they know is tired, inflamed, foggy, and anxious, so tiredness, inflammation, fog, and anxiety must be the human condition.
They are not the human condition. They are conditions. Specific, measurable, produced by specific inputs, and reversible by specific changes. Aristotle knew the difference. We forgot it.
What does adult development tell us?
Robert Kegan spent decades at Harvard studying how adults develop — not cognitively in the narrow sense, but in terms of how they construct meaning, relate to their own beliefs, and author their lives.
His framework identifies five stages. Three matter here.
Stage 3 — the Socialized Mind. Your sense of self comes from the people around you. Your beliefs are the beliefs of your group. Your values are inherited, not examined. Roughly 50% of adults operate primarily from Stage 3. They are not unintelligent. They are embedded. Their identity is a function of their social environment, and they lack the internal architecture to step outside it and evaluate whether it serves them.
Stage 4 — the Self-Authoring Mind. You can examine your own beliefs as objects rather than living inside them as subjects. You generate your own value system, set your own direction, tolerate disagreement without identity collapse. Only about 30% of adults reach Stage 4 by age thirty-five. Many never do.
Stage 5 — the Self-Transforming Mind. You can hold multiple value systems simultaneously, recognize the limits of your own framework, and operate with genuine flexibility. This is rare. Kegan estimated single-digit percentages of the adult population.
Here is where this connects to the metabolic question, and we think the connection is underappreciated. Self-authoring requires a functioning prefrontal cortex. The capacity to examine your own beliefs, hold competing perspectives, and make deliberate choices about your life — these are executive functions. They run on the newest, most metabolically expensive hardware in the brain. When that hardware is offline — when chronic stress, poor sleep, unstable blood sugar, and systemic inflammation have degraded prefrontal function — you do not have access to self-authoring.
You default to Stage 3. Not because you lack potential, but because the biological infrastructure for Stage 4 is compromised. The socialized mind is not just a developmental stage. For millions of people, it is a metabolic consequence.
Reaching Stage 4 in the current environment — actually authoring your own life rather than being authored by your conditions — already qualifies as extraordinary. Relative to the population baseline, it is superhuman. Not in the comic-book sense. In the Aristotelian sense: a human actualizing a capacity that most humans possess but few have the biological conditions to exercise.
What did Maslow actually say?
Most people know Abraham Maslow's hierarchy: physiological needs at the base, then safety, belonging, esteem, and self-actualization at the peak. The pyramid diagram is in every introductory psychology textbook. What most people do not know is that Maslow revised the model in the 1970s, near the end of his life, and the revision changes the picture significantly.
He added a level above self-actualization: self-transcendence. The capacity to go beyond individual fulfillment and connect to something larger — a cause, a community, a sense of the sacred. Maslow came to believe that self-actualization without transcendence was incomplete. The fully realized human is not the one who maximizes their own potential. It is the one who maximizes their potential in service of something beyond themselves.
The textbooks kept printing the old five-level version. The revision got buried. We think it matters because it maps the same territory this series covers.
The base of Maslow's hierarchy is biological. Physiological needs. Safety. You cannot think about belonging when you are hungry. You cannot pursue meaning when you feel unsafe. The body comes first — not because it is most important in some ultimate sense, but because without it, nothing above it is accessible.
We see this play out in the 93.2% data. A population that cannot meet basic metabolic health markers is a population stuck at the base of the hierarchy. Not because they lack ambition or intelligence, but because their biological foundation is compromised. Maslow's hierarchy is not just a theory of motivation. It is a theory of prerequisite conditions. And the prerequisites are missing for nearly everyone.
Why mind, body, and spirit are one system?
Maurice Merleau-Ponty, writing in mid-twentieth-century France, made an argument that neuroscience has spent decades confirming: you do not have a body. You are a body. Consciousness is not a ghost riding a machine. It is embodied. Your thoughts are shaped by your posture, your blood chemistry, your breathing pattern, the state of your gut. The mind-body split that Western philosophy inherited from Descartes is not just philosophically wrong. It is empirically wrong. Every attempt to study cognition in isolation from biology has produced incomplete results.
This means the three dimensions of the Superhuman — mind, body, spirit — are not three separate projects. They are one system observed from three angles. You cannot restore cognitive function without addressing metabolic health, because the brain runs on metabolic fuel. You cannot find sustained purpose without a functioning prefrontal cortex, because purpose requires the capacity for long-term planning and meaning-making. You cannot maintain biological health without meaning, because purpose changes gene expression, immune function, and recovery capacity.
We have seen, across the people we work with and the research we track, what happens when someone treats these as separate domains. They optimize their body but cannot sustain the changes because they lack purpose. They pursue meaning but cannot execute because their biology is in crisis. They sharpen their mind through cognitive tools but the improvements evaporate because the biological substrate is unstable.
The integrated approach is not a philosophical preference. It is a practical requirement. The system works as a system or it does not work.
What is this series for?
We are building this Education series as a specific contribution to a specific project. Not wellness writing. Not self-improvement advice. A documented, evidence-based account of what happens when an individual human reclaims full capacity — and what the research says about how to do it.
Next week, we examine the prefrontal cortex under chronic stress. Amy Arnsten's lab at Yale has documented, with a precision that changed how we think about every social problem we track, what happens when the brain's executive center goes dark. The mechanism is specific. The consequences are population-wide. And the reversal is possible.
The week after, we turn to metabolism — the 93.2% at the cellular level, the embodied cognition that Merleau-Ponty described and modern biology confirms, and the biological counter-movement of millions of people who decided that "normal" was a lie they could no longer afford to believe.
We do not know everything. The interaction between metabolic health, cognitive function, and meaning-making is still being mapped. Some of the positions we hold in this series are inferences, and we will mark them as such. We are not pretending to have certainty where the science is still developing.
But we know enough. We know that the human operating at capacity — Aristotle's eudaimonia, Maslow's self-transcendence, Kegan's self-authoring mind — is not a fantasy. It is a biological state. It has prerequisites. Those prerequisites are currently missing for 93.2% of the population. And reclaiming them is not enhancement.
It is becoming what you already are.
The Superhuman is not a destination above human. It is the human who stopped settling for the diminished version that everyone around them mistook for normal. The evidence says that version is available. The practice — as Aristotle insisted — is what makes it real.
We start with the brain. Your prefrontal cortex is doing something right now, as you read this, that most brains in most offices on most afternoons cannot do. Hold that thought. We will explain why next week.
