It didn't take elaborate experiments to deduce that an infant would die from want of food. But it took centuries to figure out that infants can and do perish from want of love.

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.

Paradoxically, the toddler's "No" is also a preliminary to his saying yes. It is a sign that he is getting ready to convert his mother's restrictions and prohibitions into the rules for behavior that will belong to him.

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.

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.

Adolescents are the bearers of cultural renewal, those cycles of generation and regeneration that link our limited individual destinies with the destiny of the species.
