Jun 15, 2025
They debate Laplanche’s reworking of Freud’s seduction theory and the idea that adults implant enigmatic sexual messages in infants. They unpack leaning-on and caregiving as sites of inscription.

Episode notes
Seduction As Universal Psychic Implantation
- Jean Laplanche reconceives Freud's seduction theory as universal rather than merely literal child abuse.
- He argues adults inevitably implant enigmatic sexual signifiers into helpless children, shaping the unconscious.
Sexuality Originates In The Other
- Laplanche insists sexuality is exogenous: it must come from the adult other rather than being innate in the child.
- The child's helpless dependence makes it susceptible to unconscious, enigmatic transmissions from caregivers.
Polymorphous Perversity And Sexual Indistinction
- Polymorphous perversity describes infant sexuality as undifferentiated and not genitally fixed.
- If everything sexual is flattened, Laplanche warns, then the sexual loses distinctiveness and explanatory power.
