It is an odd fact that what we now know of the mental and emotional life of infants surpasses what we comprehend about adolescents. . . . That they do not confide in us is hardly surprising. They use wise discretion in disguising themselves with the caricatures we design for them. And unfortunately for us, as for them, too often adolescents retain the caricatured personalities they had merely meant to try on for size.

What eleven- to thirteen-year-old boys fear is passivity of any kind. When they do act passively we can be fairly certain that it is an act of aggression designed to torment a parent or teacher. . . . Mischief at best, violence at worst is the boy's proclamation of masculinity.

We humans undergo two major growth spurts: one during infancy and another from eleven to twelve until fifteen or sixteen--pubescence. Between the two is a relatively quiescent growth period in which most of the body takes a rest from growing while the brain continues to mature. This period of life is general referred to as childhood or, sometimes, latency.

Adolescence represents an inner emotional upheaval, a struggle between the eternal human wish to cling to the past and the equally powerful wish to get on with the future.

Young people...have more compassion and tenderness toward the elderly than most middle-aged adults. Nothing--not avarice, not pride, not scrupulousness, not impulsiveness--so disillusions a youth about her parents as the seemingly inhumane way they treat her grandparents.

A man's fatherliness is enriched as much by his acceptance of his feminine and childlike strivings as it is by his memories of tender closeness with his own father. A man who has been able to accept tenderness from his father is able later in life to be tender with his own children.

The adolescent frequently supposes that she is breaking out of the confines of her mundane, schoolgirl existence simply in order to break rules and defy authority. . . . She rids herself of the "oughts" and "musts" that convert every minor infraction into a sin of omission or commission. It certainly does not occur to her or to her family that by questioning the moral standards she erected as a child she is taking the first steps in her journey toward a firmer, more reasonable, less harsh, more ethical form of conscience.
