Adolescence is the time to enlarge the natural sentiments of pity, friendship, and generosity, the time to develop an understanding of human nature and the varieties of human character, the time to gain insight into the strengths and weaknesses of all men and to study the history of mankind.

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.

Fathers represent another way of looking at life - the possibility of an alternative dialogue.

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.

As he walks away on his own two feet--the toddler's body-mind has reached its moment of perfection. The world is his and he the mighty conqueror of all he beholds.... As long as mother sticks around in the wings, the mighty acrobat confidently performs his trick of twirling in circles, walking on tiptoe, jumping, climbing, staring, naming. He is joyous, filled with his grandeur and wondrous omnipotence.

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.

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.
