Procreation, Asymmetry,
and the Ground of
Filial Obligation

What, if anything, do grown children owe their parents — and where could that obligation possibly come from?

The conversation so far

What do grown children
owe their parents?

For decades the answers have all been given from inside a bond that already exists.

Jane English · 1979
Nothing — by mere birth
Whatever remains is friendship, affection, and the choice to keep the bond alive.
Christina Hoff Sommers · 1986
A special moral force
Filial duty cannot be reduced to sentiment; it survives even when affection does not.
Simon Keller · 2006
"Special goods"
Not debt, not gratitude — goods only a parent and child can give each other.
One assumption unites them all: the parent–child relation is already in place. Each asks only what obligation arises within it. The shared starting point this paper rejects

This paper rewinds the tape

Before the bond,
there is an act.

Every biological filial tie begins with one thing — procreation. So ask the prior question: can the act of bringing a child into existence itself ground, complicate, or even undermine what that child later owes?

Scope · biological procreation = actual parenthood

Not "should we procreate?" — but what procreation means, and what it leaves us with.

Four Theories · 04 / 19
Act I

Four theories,
one shared flaw

Debt · Gratitude · Special Goods · Friendship. Each has been offered as the ground of filial duty. Each fails — and each fails for a related reason.

The case against the received view
— · —
Act I · Objection 01
Debt · 05 / 19
Theory 01 · Debt

Care is not a loan

No metric
Nothing tells you what the child actually owes back, or on what terms the "loan" is due.
The "full payment" absurdity
If it could be measured, one lump sum would discharge every filial duty forever.
Already owed
Choose to have a child and basic care is what you owe them — it can't become a debt they owe back.
"The notion of debt cannot specify the filial obligations we actually have." English 1979 · Keller 2006
The ledger that never balances
Objection 01
Act I · Objection 02
Gratitude · 06 / 19
Theory 02 · Gratitude

Gratitude on demand
isn't gratitude

Keller · 01 — Performance
If showing up is read as proof of gratefulness, love collapses into a performance of debt.
Keller · 02 — Scaling
More sacrifice → more owed? Then effortless, wonderful parents would be owed less. We reject that.
Keller · 03 — No heavy burdens
"Acts of benevolence should not place significant burdens upon their beneficiaries."
And per Berger: the moment a gift expects a return, benevolence becomes business — parents reduced to investors in their own old age. Berger 1975 · "a mere by-product of acts done for self-gain"
When the gift keeps a receipt
Objection 02
Act I · Objection 03
Special Goods · 07 / 19
Theory 03 · Special Goods

A monopoly is not
an obligation

Keller: only a parent and child can give each other certain goods — a "sense of continuity and transcendence." Being uniquely placed to provide them, he says, is the source of the duty.

But holding something unique for another creates no duty to hand it over. One side may simply not need the good, however special it is. And if the bond is merely a channel kept open for trade — where is the room left for altruism? Possession is not obligation.

Country A owns all the aluminium. Country B owns all the magnesium.
Both are monopolies. Neither is obligated to trade — even to make the alloy only they could make.
The exchange that no one owes
Unique ≠ owed
Objection 03
Act I · Objection 04
Friendship · 08 / 19
Theory 04 · Friendship

Friends are chosen.
Parents are not.

English: treat the bond like a friendship — keep it alive, don't tally debts. It dodges the traps of debt and gratitude, yet misses the one thing friendship never has.

"It is almost like a
slave contract —
signed by the owner alone."

The parent–child relation is historically and morally asymmetrical. A child — even in the womb — cannot consent, cannot exit, cannot choose the other party.

And Sommers' collectivist repair is worse: it lets "familyhood" overshadow the person, dissolving the individual's own value into the group's.

The asymmetry friendship can't see

Pivot · 09 / 19
What debt, gratitude & special goods have in common
All four seat parent and child at the negotiating table too early — as if both had entered on comparable footing.

They never did. To see why, we have to go back further — to the act itself.

Act II

Back to
the act itself

Not an innocent gift of life — but a unilateral decision, made for someone who is not yet there to make it, refuse it, or revise its terms.

Act II · Non-Identity
Parfit · Benatar · 11 / 19
The non-identity problem

Existence vs.
non-existence

Parfit's 14-year-old: the child born now and the child born years later come from different gametes — they are different people. "You'd have been better off born later" compares no one to no one.

Benatar re-draws the comparison: this child's existence against this child's non-existence.

Procreation is no longer a transfer of benefit to someone waiting to receive it. It brings a subject into being — one who must then bear whatever life contains. The innocence of the "gift of life" is gone
Two people, not one better-off child

Act II · Authorship
The Analogy · 12 / 19
The authorship problem

Kevin's shooting range

The analogy

Kevin hands out bulletproof vests to his neighbours — generous. But Kevin also built the shooting range in his backyard, in a gun-free street. The danger was his own work. No one owes him gratitude for the vests.

Procreation

Parents author the very vulnerability their care later answers — and the child never consented. Coming into existence is no creditable gift; the care is no favour. Authorship dissolves the altruism.

Nor can the motive be purely for the child — before procreation there is no child to benefit. And "a good life" is the parents' definition; what they intend as a benefit, the child may later live as a burden.

Act II · Asymmetry
Where the Weight Falls · 13 / 19
Why the moral burden lands on the parents

Three asymmetries

i.
Autonomy
Parents choose freely. The child — even as a foetus — has none. Every decision is made for them.
ii.
Pleasure & pain
Benatar: absent pain is good; absent pleasure harms no one — there is no one there to be deprived.
iii.
Risk
Existence carries risk — accident, ageing, disease, death. Non-existence carries none. Risk imposed without consent demands an answer.
The third is this paper's own: a risk-based asymmetry. However small the risk, imposing it unilaterally — with no prior consent — is what must be treated with concern. Rights come with responsibilities
The scales were never even
Asymmetry
Act III · The Reversal
Compensation · 14 / 19
A reversed debt theory

The debt
runs backward

The child does not begin owing gratitude for the gift of life. The parents begin owing justification, care, and ongoing responsibility for a decision they made alone. Parenting is not a loan to be repaid — it is compensation for the risk they authored.

Compensation theory

Act III · Risk & Consent
The Gamble · 15 / 19
Risk & consent

Dragged to
the table

With Shiffrin: procreation isn't always wrong — but creating a life exposed to risk, without consent, is morally serious.

Weinberg replies that the odds are good, and that parents may consent on the child's behalf. But a swimmer enters the water willingly; the child never does. And "parent" is not a role you fall into — it is a role you create by throwing another into it. You cannot claim paternal authority over a game you dealt someone into.

"Dragging someone to the table — without letting them see the rules or the risk — is usually wrong." Life is a gamble no one asked to play

Would you have said yes to huge vulnerability and certain pain, sight unseen?

Hypothetical consent isn't consent
Risk & Consent
Act III · The Gap
Where From? · 16 / 19
If parenting is only compensation…

Best-placed ≠ obligated

If raising a child merely repays a debt the parents owe, then it generates no new debt in the child. So where could filial obligation come from at all?

Adult children often are the best-placed to help their parents. But being best-placed for a role is not the same as being bound to it — just as holding a unique good never obliged the trade.

So it cannot be inherited at birth.
It has to be built — after the
child becomes a competent adult.
Nothing is owed automatically
The Gap
Act IV · A New Ground
Decision-Making · 17 / 19
What is actually universal

The real currency is
decision-making

Generic goods — money, care, transport — anyone can supply. What every human needs is a good decision, made by someone who truly knows them.

Criterion 01
Value
Someone who knows what you actually care about — your religion, your fears, your idea of a life worth living.
Criterion 02
Trust
Someone you would hand the wheel to when you no longer can — a medical call, a final wish, a hard choice.
Children rely on parents to decide well before adulthood; parents later lean on children. That mutual decision-making — not debt, not gratitude — is where filial obligation actually lives.
Value + trust
A New Ground
Act IV · Why Your Child?
Sunk Cost · 18 / 19
Why your child, and not a trusted old friend?

The sunk cost of
twenty years

A friend of thirty years could advise your parents too — recall English's estranged Vance. So why the deep instinct that children are the best choice? Two decades of intimate living build value and trust that no substitute cheaply replaces.

Not economics' wasted sunk cost —
emotion that legitimately shapes
judgment, and should be acknowledged.
And when parents only ever controlled — never respecting the child's own decisions — the obligation never forms. That is Vance. Obligation is earned, or it isn't there
Trust, accumulated over a lifetime
Sunk Cost
Coda · The Takeaway
Fin · 19 / 19
What we should cherish
Filial obligation is not a must. Care is not a loan, nor a debt of endless gratitude.

What deserves to be cherished is decision-making itself — the choice to hand your wheel to someone who knows you deeply and has earned your deepest trust.
