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.

Young people...have more compassion and tenderness toward the elderly than most middle-aged adults. Nothing--not avarice, not pride, not scrupulousness, not impulsiveness--so disillusions a youth about her parents as the seemingly inhumane way they treat her grandparents.

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

Adolescence is the conjugator of childhood and adulthood.

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.

Adolescence is a time of active deconstruction, construction, reconstruction--a period in which past, present, and future are rewoven and strung together on the threads of fantasies and wishes that do not necessarily follow the laws of linear chronology.

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.
