This paper deals with the intrinsic relationship between adoslence definition and juveline delinquence, based upon philanthropy, and Judicial Treaties from the XIX century, from where the "ideal" adolescent was borrowed . It results from an analysis of (Psycho) Pedagogy books and texts from the first decades of the XX century until the seventies - which by using their jargons, designed definitions which led to problematic situations, and so scientifically identified a new ADOLESCENCE. This paper explains why there are late phases of adolescence - as the rebel without a cause and the revolutionary young man - and consequently new characters are created, and the image of the criminal juveline remained in the social imaginary,thus defining and procastinating his/her fate.
