Infancy is the realm conveyed to us in dreams which look backward to the past. Adolescence, more like a work of art, is a prospective symbol of personal synthesis and of the future of humankind. Like a work of art that sets us on the pathway to new discoveries, adolescence promotes new meanings by mobilizing energies that were initially invested in the past.

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.

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.

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.

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.

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.

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.
