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.

In every adult human there still lives a helpless child who is afraid of aloneness.... This would be so even if there were a possibility for perfect babies and perfect mothers.

The purpose of adolescence is to revise the past, not to obliterate it. . . . Adolescence entails the deployment of family passions to the passions and ideals that bind individuals to new family units, to their communities, to the species, to nature, to the cosmos. Therefore, given half a chance, the revolution at issue in adolescence becomes a revolution of transformation, not of annihilation.

Though they themselves might be as surprised as their parents and teachers to hear it said, adolescents--these poignantly thin- skinned and vulnerable, passionate and impulsive, starkly sexual and monstrously self-absorbed creatures--are, in fact, avid seekers of moral authenticity. They wish above all to achieve some realistic power over the real world in which they live while at the same time remaining true to their values and ideals.

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.

Another potentiality of our irrepressible juvenility is a capacity to maintain until the onset of senility an active creative interaction with our environment. We persist in exploring, investigating, inventing, discovering. In these respects humans of all eras, in all societies, all ages of life, are more like baby chimps and not at all like the sedate and rigidly conforming adult chimpanzee, who hasn't changed much since she was five or six years old.

Hopefulness is the heartbeat of the relationship between a parent and child. Each time a child overcomes the next challenge of hislife, his triumph encourages new growth in his parents. In this sense a child is parent to his mother and father.
