Whereas the child is chiefly playful and experimental, the adult focuses on specific and conscious experiences. He practices selective inattention to the objects for which he has no immediate use and develops a kind of tunnel vision that helps him to move toward selected goals. This focusing on a limited range of experiences and goals is largely responsible for one's individual evolution and gives a deep and almost tragic significance to a statement made by Albert Camus in his novel La Chute: "Après un certain âge tout homme est responsable do son visage." An almost identical statement appears as the last entry in George Orwell's notebooks: "At 50, everyone has the face he deserves." There could not any more absolute affirmation of belief in personal responsibility for the quality of one's own life and character.
