To classify the contents of the collective unconsciousness which he had just discovered, Jung made use of typology. Later, beginning in the 1940s, he adopted the concept of archetypal field (relational and energetic), emphasizing the dynamic of opposites. Drawing inspiration from the field concept, the author shows the active role taken in the transference relationship by the opposites ‘strange’ and ‘familiar’ - defined as antinomic values - and studies the therapeutic conditions for a transition from one pole to the other, in neurotic and borderline cases. The clinical examples are drawn from Théodore Flournoy's book, Des Indes à la planète Mars (From India to the Planet Mars), and two films, Theorem by Pasolini and Hiroshima mon amour by Alain Renais and Marguerite Duras.
