Through a brief linguistic and anthropological reading, the author isolates the structuring representations of the street. He then interrogates the vacuity of this street and formulates an hypothesis which articulates the emptiness of the street with the incapacity of the adolescent’s human environment. For him, the street’s explosions are the reflection of the adult’s incoherence and insufficiency. Through a clinical case, the author proposes framework for constructing a network in a troubled neighborhood. For the author, this methodology implicates clinical psychology and psychoanalysis in the social field.
