ABSTRACT
In practice, it is by means of this pubertaire step that the entry into adolescence is ordinarily determined. However, at the other extreme, at the exit from adolescence, it will be mainly social criteria that will allow us to determine whether a young person has attained adult status. Jean-Jacques Rassial has said that "adolescence is an age where the imaginary matters". The emergence of the subject of a personal speech, and the conditions for this emergence, constitute the crucial issue of the adolescent passage, an issue corroborated a contrario by the peculiar frequency of psychotic breakdown at this age. The provocation of crisis in the ideal imaginary references that generally characterize adolescence will highlight the need for the subject function to exercise itself in a repeated and effective play of drive activity — which is also corroborated by the teachings of sublimation.
