The relations between parents and children are certainly not only those of constraint. There is spontaneous mutual affection, which from the first pr… - Jean Piaget

Genetically speaking, the explanation both of rites and of symbols would seem to lie in the conditions of preverbal motor intelligence. When it is presented with any new thing, a baby of 5 to 8 months will respond with a dual reaction; it will accommodate itself to the new object and it will assimilate the object to earlier motor schemas. Give the baby a marble, and it will explore its surface and consistency, but will at the same time use it as something to grasp, to suck, to rub against the sides of its cradle, and so on. This assimilation of every fresh object to already existing motor schemas may be conceived of as the starting point of ritual acts and symbols, at any rate from the moment that assimilation becomes stronger than actual accommodation itself.

"Every observer has noted that the younger the child, the less sense he has of his own ego. From the intellectual point of view, he does not distinguish between external and internal, subjective and objective. From the point of view of action, he yields to every suggestion, and if he does oppose to other people's wills — a certain negativism which has been called "the spirit of contradiction" — this only points to his real defenselessness against his surroundings. A strong personality can maintain itself without the help of this particular weapon. The adult and the older child have complete power over him. They impose their opinions and their wishes, and the child accepts them without knowing that he does so."

A second prefatory question faces us: that of society and the individual. We have sought to contrast the child and the civilized adult on the ground of their respective social attitudes. The baby (at the stage of motor intelligence) is asocial, the egocentric child is subject to external constraint but has little capacity for cooperation, the civilized adult of to-day presents the essential character of cooperation between differentiated personalities who regard each other as equals. There are therefore three types of behavior: motor behavior, egocentric behavior (with external constraint), and cooperation. And to these three types of social behavior there correspond three types of rules: motor rules, rules due to unilateral respect, and rules due to mutual respect. But here again, one must beware of laying down the law: for things are motor, individual and social all at once. As we shall have occasion to show, rules of cooperation are in some respects the outcome of the rules of coercion and of the motor rules. On the other hand, coercion is applied during the first days of an infant's life, and the earliest social relations contain the germs of cooperation. Here again, it is not so much a question of these successive features themselves as of the proportions in which they are present. Moreover, the way in which conscious realization and the time-lag from one level to another come into play is a further bar to our arranging these phenomena in a strict sequence, as though they made a single appearance and then disappeared from the scene once and for all.
