Schoolchildren make up their own rules and enforce their own conformities. They feel safest when leisure time is rationed and dosed. They like to wear uniforms, and they frown on personal idiosyncrasies. Deviance is the mark of an outsider.

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.

Another reason for the increased self-centeredness of an adolescent is her susceptibility to humiliation. This brazen, defiant creature is also something tender, raw, thin-skinned, poignantly vulnerable. Her entire sense of personal worth can be shattered by a frown. An innocuous clarification of facts can be heard as a monumental criticism.

Other people--grandparents, sisters and brothers, the mother's best friend, the next-door neighbor--get to be familiar to the baby. If the mother communicates her trust in these people, the baby will regard them as delicious novelties. Anybody the mother trusts whom the baby sees often enough partakes a bit of the presence of the mother.

During adolescence imagination is boundless. The urge toward self-perfection is at its peak. And with all their self- absorption and personalized dreams of glory, youth are in pursuit of something larger than personal passions, some values or ideals to which they might attach their imaginations.

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.

In all times and in all places--in Constantinople, northwestern Zambia, Victorian England, Sparta, Arabia, . . . medieval France,Babylonia, . . . Carthage, Mahenjo-Daro, Patagonia, Kyushu, . . . Dresden--the time span between childhood and adulthood, however fleeting or prolonged, has been associated with the acquisition of virtue as it is differently defined in each society. A child may be good and morally obedient, but only in the process of arriving at womanhood or manhood does a human being become capable of virtue--that is, the qualities of mind and body that realize society's ideals.
