Abstract: The point of departure of the article is thedisagreements about theory and techniquein the British Society. Fantasies of being“the owner” of psychoanalytic father ormother are described, for each group. Overtime, the solutions involved institutionalarrangements, then theoretical andtechnical rapprochements between groups. The over-valuation of one aspect or anothercan lead to exaggerations or diminutions inthe technique which are not suitable for theanalysis. The author illustrates his ideaswith two scenarios, of Winnicotian andKleinian approaches.
