René Roussillon : linking, attachment, and the sexual

There are two modes of theorization that divide the favor of clinicians : one based on the theory of attachment and the other emblematized by infantile sexuality. Both appear to offer inarguable clinical benefits and yet they seem opposed to each other. Perhaps it would suffice to wait for an elaboration of the « narcissism of small differences » to do its work for a third form of theorization to subsume, in a third utterance, the ones that appeared contradictory or antagonistic. It is a matter of designating the particular modalities of interiorizing the subjective experience of the relation with oneself and with the other, the other who is so different from oneself, and to bring it forward. Can it be thought that the way in which the subjective experience will be interiorized is totally different from this?
