We belong to that order of mammals, the primates, distinguished by its propensity for repeated single litters, intense parental care, long life-spans, late sexual maturity, and a complex and extensive social existence... Our protracted biological and psychological helplessness, which extends well into the third year of life, intensifies the bond between infant and parents, making possible a sense of generational continuity. In contrast to other primates these bonds are not obliterated after sexual maturity.

Normally an infant learns to use his mother as a "beacon of orientation" during the first five months of life. The mother's presence is like a fixed light that gives the child the security to move out safely to explore the world and then return safely to harbor.

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.

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.

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 most significant change wrought by adolescence is the taming of the ideals by which a person measures himself. . . . Love of oneself becomes love of the species. Conscience is pointed to the future, whispering permission to reach beyond the safety net of our ordinary and finite human existence.

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.
