“The fact is that it is very rare for the infantile world to maintain itself beyond adolescence. From childhood on, flaws begin to be revealed in it. With astonishment, revolt and disrespect the child little by little asks himself, “Why must I act that way? What good is it? And what will happen if I act in another way?” He discovers his subjectivity; he discovers that of others. And when he arrives at the age of adolescence he begins to vacillate because he notices the contradictions among adults as well as their hesitations and weakness. Men stop appearing as if they were gods, and at the same time the adolescent discovers the human character of the reality about him. Language, customs, ethics, and values have their source in these uncertain creatures. The moment has come when he too is going to be called upon to participate in their operation; his acts weigh upon the earth as much as those of other men. He will have to choose and decide. It is comprehensible that it is hard for him to live this moment of his history, and this is doubtless the deepest reason for the crisis of adolescence; the individual must at last assume his subjectivity.”
