This text looks at the question of the feminine dimension which will be examined from a threefold perspective of: sexual identity, father / son filiation and otherness. Particular attention will be paid to the place of the feminine dimension in the psychosexual development of the male child and the incidences that the father / son relationship can produce on it. The examination of the stopping point that the feminine dimension constitutes and which, from father to son, forms the object of a trans-generational repetition, can shed further light on the nature of what Freud called “the dark continent”.
