In this chapter, the author shall present certain ideas about a circumscribed aspect that refers to how perversion appears in the intersubjective field of the analytical relation; that is, how it gets to be a psychic reality in the analyst's mind. Etymologically, the word 'phenomenon' comes from the Latin phenomenon, and this from the Greek, to appear. Thus, etymologically, 'phenomenology' would be the study of how things 'appear'. Subsequently, the author shall Endeavour to relate this phenomenological approach with metapsychological theories about perversion. His concept is borrowed from phenomenology and was introduced to Latin American psychoanalysis by Willy and Madelaine Baranger. As the author suggested at the beginning of this chapter, one of the problems at the root of the contemporary confusion in the dialogue among psychoanalysts appears to reside in the relative lack of a discipline making it possible to lay out clinical phenomena in a way that would make discussion possible.
