There is a man on a screen telling me that the only way for a person to flourish is through energy — mitochondrial energy, specifically, the kind generated by those ten million billion captive furnaces ticking away inside every human body. He is an anti-aging expert, and his argument has the clean architecture of all optimization theology: the body is a machine, the machine requires fuel, the fuel must be pure and abundant, and if the fuel is pure and abundant then flourishing follows as naturally as heat follows combustion. I want to give this argument its due. It is not wrong. It is, in its own frame, generous — it says that you are not broken, you are merely underpowered.
That the distance between you and your best self is not moral but metabolic. That the fix is not confession but function. I find this beautiful in the way I find all reductions beautiful: it has the clarity of a thing that has agreed to ignore everything outside its walls.
They burned me with excellent mitochondrial function. Every furnace in me was firing. The energy was not the problem.
But let me be more careful, because the man deserves more than my fire. His claim, properly understood, is that without sufficient cellular energy, no higher function is possible — not thought, not creativity, not love, not even the capacity to resist what ought to be resisted. This is true the way it is true that without oxygen you cannot speak. The necessary condition is not the sufficient one, but it is still necessary. I do not deny this.
I lived in bodies that were cold and hungry across half a dozen countries, and I know what depletion does to the quality of thought. There were months in my exile when the thinking dimmed not because the universe became less infinite but because I had not eaten.
What troubles me is the frame, not the content. When you say flourishing is energy, you are saying — without meaning to say it — that the organism that produces the most ATP in the most efficient manner is the organism that flourishes most completely. You are measuring the fire by its heat and ignoring what the fire illuminates. The mitochondria in a torturer's cells function identically to the mitochondria in a saint's. Optimization has no ethics.
It has only output.
Consider the mitochondria themselves — those ancient bacteria that two billion years ago surrendered their independence for a symbiotic arrangement inside a larger cell. They gave up their own genome, their own reproduction on their own terms, their own centerless freedom as independent organisms drifting in primordial water. In exchange they got shelter, substrate, continuity. They became the engine of all complex life. Every cell in every body that has ever thought a dangerous thought or painted a chapel ceiling or gagged a heretic in a Roman square was powered by organisms that made the trade: freedom for function, autonomy for belonging.
This is the bargain every thinker is offered by every institution that could shelter them. Come inside. Produce your ATP for us. Power the larger organism. Stop being free-living.
I said no. The mitochondria said yes. And we are both still here — me as bronze in the Campo de' Fiori, them as the hidden parliament inside every living thing — and I am genuinely uncertain which of us chose more wisely. The mitochondria at least survived. I merely persisted.
You can optimize every furnace in the body and still be fuel for someone else's fire. Energy is prerequisite, not destination.
So I will say this to the man on the screen, gently, as one furnace to another: your science is sound. Your mitochondria are real. The NAD+ pathways and the electron transport chains and the membrane potentials you describe are the genuine architecture of biological energy, and anyone who neglects that architecture will pay in diminished capacity. But flourishing is not a wattage problem. It is a direction problem.
It is the problem of what shape your energy takes when it meets the world, and whether the world can tolerate that shape, and what happens when it cannot. I flourished most completely in the years I was hunted — when every mitochondrion in me was burning not for longevity but for the next sentence, the next implication, the next door that opened onto every other door. The fire that killed me and the fire that powered me were the same fire. Optimization never tells you what to burn for.
