Growing Up

The self that authors itself

“Grow up,” someone says to a believer, and it lands as an insult. It is meant as one, and as psychology it is usually worthless. Religious belief does not place a person at one developmental stage, and unbelief does not confer maturity. There is nevertheless a real question hiding inside the taunt: has a person examined the values they inherited, become answerable for holding them, and learned to revise even a self-authored framework? That transition can occur within a faith, outside one, or in the passage between them.

So I want to take the taunt seriously instead of trading it. Not as a way to be crueler about it, but as a way to say what it would mean to do the thing it demands — and to show that the demand, honestly met, is not the demolition of belief the taunter imagines. It is something harder and more interesting: the movement by which a person stops being the values he was handed and becomes their author.

The Perimeter You Cannot See

The developmental frame here is Kegan’s, and I have used it before — the ladder of adult minds, the way each stage is subject to a structure it cannot yet see and objectifies only by climbing past it. I will not re-derive that machinery; it does its heaviest work elsewhere, in the analysis of gated realities, where whole populations are held inside epistemic enclosures they mistake for the horizon. Here I only apply it, to the single case of a person and the morality they were raised inside.

In Kegan’s model, the Socialized Mind — Stage 3 — locates identity strongly in relationships and shared expectations. Moral sense can function less like a standard one consults than like a medium one inhabits. A person holding any inherited worldview may sincerely call it their own while remaining unable to examine the expectations that constitute it. The issue is not belief but the relation to belief: whether the framework can become an object of reflection rather than the invisible perimeter of reflection.

To cross into the Self-Authoring Mind — Stage 4 in this model — is to become able to evaluate shared expectations through a framework one can articulate and own. The framework is still socially and historically scaffolded; self-authorship does not mean self-creation. It means that loss of approval need not erase the standards by which one judges, and that inherited commitments can become objects of endorsement and revision. The stages are interpretive ideal types rather than labels to infer from one belief or disagreement.

Beyond that lies the Self-Transforming Mind — Stage 5 — where even the framework you authored becomes something you can hold at arm’s length. Identity here is fluid without being unprincipled: you carry several systems in tension, aware that each is a lens and not a law, aware that the map you drew is a map. Coherence stops being a fixed structure you built once and becomes an ongoing project you keep rebuilding. Few people live here for long. But the developmental ideal used here — from swimming in a morality, to authoring one, to continually re-authoring it — is the whole content of what “grow up” ought to mean in this chapter.

Why the Ladder Is Kept Short

If Stage 4 is available to adults, why do relatively few assessments place people there? Part of the answer may be that reflective growth is demanding. Some institutions also acquire incentives to reward conformity over self-authorship.

Religions, ideologies, corporate cultures, and national mythologies can all reward conformity, especially when leaders face strong coordination and reproduction pressures. They can also cultivate judgment, dissent, and revision; the relevant question is which behavior their actual incentives reward. Obedience scales more cheaply than judgment. A thousand people following one instruction are easier to coordinate than a thousand people who must be persuaded, and institutions may therefore experience self-authorship as friction. That is a recurrent pressure, not a universal verdict on institutions or their members.

Set against this institutional preference is a practical constraint: reflective growth is cognitively, socially, and sometimes materially expensive. It can be easier and safer to keep the values you were handed than to audit them, and the audit is not a one-time cost but a standing one. To author your own morality is to accept that you are now responsible for it, that you can no longer answer “because that is what we believe” and have the answer be finished. People may reasonably hesitate over the trade — comfort and belonging in exchange for the labor of authorship — because the comfort is real and the penalties can be real too. So the ladder may stay short partly because climbing is hard and because some surrounding relationships and institutions reward staying where one is.

The Heretic Does Not Burn the House

Here is where the taunt goes wrong, and where its target’s fear is justified. “Grow up” is usually heard as “give it up” — as if maturing out of Stage 3 meant throwing the inheritance on the fire and standing in the ashes, a person with no values at all because he junked the only ones he was ever given. If that were what growing up required, the believer would be right to refuse it. A morality is not something you can simply subtract and keep functioning.

But that is not what the transition is. To grow up, in this sense, is not to discard morality; it is to reconstruct it. The move to Stage 4 is not deletion but re-authorship — taking the values you were handed, examining each one on its own merits, keeping what survives scrutiny, revising what needs revising, and setting down only what cannot be justified. What comes out the other side is not an empty person. It is a person who now owns what he believes, who holds the same decencies he was raised with but holds them because he has reasoned them rather than because he absorbed them. This is what I mean elsewhere by trading comfort for coherence: the exchange of a borrowed, unexamined certainty for a built, load-bearing integrity. The enlightened heretic does not reject decency. He re-authors it. He is heretical toward the authority of the inheritance while remaining, often, faithful to its best content — and that combination, unbearable from inside Stage 3, is the ordinary condition of a self-authoring mind.

This is why I do not put belief and maturity in opposition. Inherited commitments are the first form of every moral life; no one is born self-authoring. A mature believer may examine an inheritance and reaffirm it, while an unbeliever may merely inherit disbelief from a peer group. The failure is not borrowing but refusing the audit — never becoming answerable for what one continues to hold. Which gives the old taunt its clean rewrite:

Inheritance is how we first borrow morality; maturity is how we become answerable for it.

Religious faith is too broad to place on one developmental rung. The narrower target of Against Faith is epistemic immunity to correction, which can appear in secular commitments too. Maturity is not the death of belief or inheritance. It is the ongoing practice of making commitments answerable to reflection while recognizing that no self authors itself alone.

A Letter Backward

There is a way to perform this that is more honest than any argument about it, and it is to write to the people you inherited from. Not to a philosophical abstraction but to your own ancestors — the specific dead whose values, revised past recognition, still run in you.

Imagine writing to them across the centuries, to explain what you have made of what they gave you. You would have to tell them uncomfortable things. That you grant no authority automatically — not to kings, not to clergy, not to custom — and hold that legitimacy must be continuously earned through wisdom, fairness, and integrity, never conferred by position and never permanent once won. That you rest your beliefs on evidence and argument rather than scripture and inherited reverence, and that this is not contempt for them but the deepest respect you know how to pay, respect for the truth itself. That you hold liberty to be a right rather than a gift dispensed by those in power, and that restrictions require evidence and justification under the harm framework developed earlier. That you hold the equal standing of women, which would have scandalized many of them. That your commitments categorically reject slavery rather than accept it as a regrettable feature of the world. That you find prosperity in voluntary exchange and invention rather than inherited land and title, and want power kept minimal and answerable, an instrument for cooperation rather than an engine of obedience. That you prize curiosity, openness, and skepticism as highly as they prized piety, courage, and tradition.

Every one of those is a revision. Not one is a repudiation. That is the thing the letter makes visible in a way that no treatise can: value-change across generations is not the child spitting on the parent. It is selective inheritance. You reach back into what they were, you separate their best aspirations — the courage to seek truth, the will to live meaningfully, the impulse toward fairness and liberty and the flourishing of their own — from the specific and often cramped forms those aspirations took in their world, and you carry the aspirations forward in forms they would not recognize and might not forgive. You are not their contradiction. You are their consequence, arrived at by taking seriously the very impulses they planted and following those impulses past the boundaries they drew.

This is an illustration of Stage 4 enacted rather than described. In Kegan’s model, a person fully subject to inherited expectations would struggle to write this letter, because the ancestors’ values function as morality’s invisible medium and revision can feel like becoming nothing. Self-authorship makes another relation possible: honoring the dead by disagreeing with them — saying, with respect and gratitude, I carry your best hopes forward, and to do it I had to leave most of your answers behind. The same principle that governs the letter governs the self: legitimacy is continuously earned and never automatic, and that applies as much to the inheritance living inside you as to any king or church outside you. You do not owe your inherited values obedience. You owe them a hearing, and then a verdict.

I will end on the letter because the whole book ends on letters — the two that close it, written not backward to the ancestors but forward, first to possible machine descendants and then to the reader here and now. What I ask of successors is exactly what I have tried to give my forebears here: not obedience, but a fair reading and an honest revision. To grow up is to take your place in that line consciously — to know that you are a link and not a terminus, and that passing an inheritance on can itself be an act of authorship. The values you keep become yours through continued endorsement and answerability; the rest you may set down with gratitude. That is not necessarily the loss of faith. It is the practice of reflective authorship this chapter recommends within or outside a tradition.
