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 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.

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.

Children, even infants, are capable of sympathy. But only after adolescence are we capable of compassion.

We humans, once we have become emotionally invested in a homeplace, a prized personal possession, or, especially, in another person, find it immensely difficult to give them up....Because they were made at a time of life when we were utterly dependent on them, the love attachments of infancy have inordinate power over us, more than any other emotional investment.

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.
