The Child's Knot: A Mendelian Map of Psychic Structure

We are all, in a sense, “crazy.” What differs is the way each of us manages our madness.

Most of the time, we perform as the ‘Symbolic Subject,’ or what I like to call the ‘Symbolic Man’: a coherent, ethically balanced being who negotiates lack, desire, and law without succumbing to abuse or excess. The Symbolic Man is a mask: it centers us, containing the deeper structures beneath. Yet in moments of crisis, the mask cracks: anger, despair, or obsession expose the hidden architecture of our psyche: perversion (P), neurosis (N), or psychosis (S).

The brilliance of the human mind is that even in childhood we intuit how the domestic world is structured. Long before abstract reasoning, we register (with uncanny precision) the codes of the family field: the way father and mother stage desire, the climate of enjoyment, the fractures in law. The child then positions themself within this field, not passively but creatively.

The idea is this: the child does not simply inherit traits; they invent a psychic stance that resolves the contradiction between the parental positions. The psyche of the child is a living compromise, a triangulated solution for the parental problems.

A Note on This Model

What follows is a theoretical heuristic, a tool for thought, not a deterministic formula. It is grounded in the psychoanalytic traditions of Freud and Lacan, which work with symbolic logic rather than genetic inheritance or statistical models.

  • N, P, S are structures, not pathologies. They name underlying frameworks of desire and law, not fixed behaviors or psychiatric labels.
  • “Mother” and “Father” are symbolic functions, not genders. The maternal represents demand and care; the paternal represents symbolic law and separation. Any caregiver can embody these roles.
  • This model is probabilistic, not fatalistic. It describes symbolic gravity — a pull — not certainty. A child’s own creativity, along with modifiers such as trauma, siblings, or culture, determine the final outcome.
  • It does not ignore biology. This is a structural lens that interacts with, but does not reduce to, temperament, genes, or neurochemistry.

Think of it less as a verdict and more as a mirror, a way to spark reflection about how unconscious contradictions shape psychic life.

The Mendelian Metaphor

I borrow the Mendelian grid as metaphor, not as biology. Each parental position functions like a dominant psychic “trait”: N, P, or S. When two positions meet, the child invents a structure that resolves (or fails to resolve) their tension.

  • N = Neurosis: bound to the implicit law, generating guilt, obsessions, and repression.
  • P = Perversion: staging the law as a theatrical game, in pursuit of jouissance and control.
  • S = Psychosis: foreclosure of the paternal signifier, producing a gap (or lack) in symbolic order.

The “Mendelian grid” of possible combinations does not predict destiny but shows the likely compromises.

Typical Syntheses

N × P → Child ≈ S (with Defensive Variants)

  • Trajectory: The neurotic parent insists on law, the perverse parent undermines it. The contradiction often pushes the child toward psychotic solutions (S) — private rituals or delusional logics that stabilize the irreconcilable.
  • Variants: If the perverse parent is overvalued (OV), the child may imitate them; if the neurotic law dominates, obsessive rigidity (Defensive N) may emerge.
  • Prediction: Psychosis is the gravitational pull; defensive neurosis or perversion arise depending on which parental pole dominates.

N × S → Child ≈ P

  • Trajectory: A weak neurotic law plus a psychotic void creates a symbolic vacuum. The child often stages perverse order (P) — performing rules to hold things together.
  • Mechanism: The child becomes a “false legislator,” wielding rules as external props rather than internalized law.
  • Prediction: Perversion is the dominant tendency, a theatrical patch over the void.

P × S → Child ≈ S (with rare Neurotic invention)

  • Trajectory: The perverse parent disavows the law; the psychotic parent forecloses it. With no stable symbolic mediation, the child is exposed to raw jouissance.
  • Main prediction: Psychosis is the gravitational pull — the child lacks a ready-made symbolic anchor.
  • Neurotic variant: In rare cases, the child invents a neurotic law ex nihilo. This can happen if:
    • a weak paternal figure still provides a minimal trace of law,
    • external authority (teachers, institutions, books, etc.) is introjected, or
    • the child rigidly self-legislates to survive.
  • Result: A surprisingly coherent neurotic structure may emerge, though often marked by rigidity, overcompensation, or excessive moralism.

N × N → Child ≈ N

  • Trajectory: Two neurotic parents provide a coherent symbolic framework; the child tends toward neurosis.
  • Variants: If paternal function is weak, psychotic cracks may appear.
  • Prediction: Stable neurosis, unless fragility destabilizes.

P × P → Child ≈ S or Defensive N

  • Trajectory: Two perverse parents create chaos; the child gravitates toward psychosis.
  • Variants: Some invent rigid, obsessive defenses (Defensive N) to create an island of stability.
  • Prediction: Psychosis is frequent; defensive neurosis is a survival invention.

S × S → Child ≈ S (rare N variant)

  • Trajectory: Psychosis is normalized as the family atmosphere; the child tends to adopt it.
  • Variants: Occasionally, one child invents obsessive rules (compensatory N) — but this is fragile and compulsive.
  • Prediction: Psychosis dominates; neurotic solutions are rare and defensive.

The Grid (Symbolic Gravity, not Destiny):

Modifiers, Why Outcomes Vary

Not all parental traits weigh equally; some function like dominant alleles. Narcissism, for instance, often overrides subtler neurotic or psychotic signals. To refine the map, several contextual modifiers must be considered:

  • OV (Overvaluation / Narcissistic Domination) → pushes toward perverse/narcissistic identification.
  • PF (Strength of Paternal Function) → stabilizes neurosis if strong; opens psychotic cracks if weak.
  • LC (Lack of Mirroring / Coldness) → produces “fragile narcissism” or defensive grandiosity.
  • SM (Sibling Mediation) → siblings distribute roles; one becomes the law-bearer, another embodies maternal jouissance, another collapses psychotically.
  • TT (Timing, Trauma, Culture) → external shocks and social norms alter trajectories.

These ensures the schema and the analysis remains dynamic rather than mechanical.

Sibling Division of Labor

Where there are multiple children, the family contradiction is rarely borne by one alone. Roles get distributed: one becomes the enforcer of rules, another the rebel, a third the scapegoat or the fragile carrier of psychotic cracks. Each develops a psychic stance to maintain a precarious equilibrium within the family system. Birth order matters: later children inherit a reshaped symbolic field, often lighter but sometimes more fragmented.

This resonates with Murray Bowen’s family systems theory, where children differentiate by managing emotional triangles within the family system. Lacan adds the psychic grammar: the “solution” each child invents is not random but constrained by the codes of desire and law staged by the parents.

Seeing the child as a triangulated solution changes the ethical frame. Psychopathology is not mere 'inheritance'; it is the child’s creative act of survival, a teleological invention to stabilize the family’s broken symbolic balance. The child is not just a victim of parental pathology but an unconscious, highly sophisticated engineer of psychic compromise in search of safety and inner stability.

Tools for Self-Analysis in Complex Families

We do not know what we do not know. The 'madness' we perform is often invisible to us. To solve a problem, we must first give it a name. Naming the structure is the beginning of liberation. Here are some starting points:

  • Map the Triad: Place each parent’s dominant position (N, P, S) and ask how the child — yourself included — might be embodying their tension.
  • Identify Modifiers: Was there narcissistic domination (OV)? A weak paternal function (PF)? Coldness or trauma (LC/TT)?
  • Notice Sibling Roles: Who in the family carried the obsession? The rebellion? The psychotic fragility? Seeing the distribution clarifies the systemic logic.
  • Borrow Both Lenses: Bowen teaches us to look at the family as an emotional system, Lacan shows us the symbolic codes. Using both together sharpens self-understanding.
  • Name Before Acting: Once you can say, “This is my neurosis,” or “This is a perverse staging,” the symptom stops being a mystery and becomes a knowable structure. From there, real strategies can be invented.

The three Lacanian categories are not prisons but coordinates. ways of reading the unconscious logic beneath what psychiatry fragments into labels separately: depression, OCD, narcissism, borderline, paranoia.

The point is not to fix yourself into a box.
It is to understand the box you found yourself in.

Only then can a subject begin to invent an exit.
