"Before games are played in common, no rules in the proper sense can come into existence. Regularities and ritualized schemas are already there, but these rites, being the work of the individual, cannot call forth that submission to something superior to the self which characterizes the appearance of any rule."

“As Bovet has demonstrated in the field of morals, rules do not appear in the mind of the child as innate facts, but as facts that are transmitted to him by his seniors, and to which from his tenderest years he has to conform by means of a sui generis form of adaptation. This, of course, does not prevent some rules from containing more than others an element of rationality, thus corresponding to the deepest fundamental constants of human nature. But whether they be rational or simply a matter of usage and consensus of opinion, rules imposed on the childish mind by adult constraint do begin by presenting a more or less uniform character of exteriority and sheer authority. So that instead of passing smoothly from an early individualism to a state of progressive cooperation, the child is from his first year onwards in the grip of coercive education which goes straight on and ends by producing what Claprède has so happily called a veritable "short circuit.”

“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.”

“In this way things, external objects, are assimilated to more or less ordered motor schemas, and in this continuous assimilation of objects the child's own activity is the starting point of play. Not only this, but when to pure movement are added language and imagination, the assimilation is strengthened, and wherever the mind feels no actual need for accommodating itself to reality, its natural tendency will be to distort the objects that surround it in accordance with its desires or its fantasy, in short to use them for its satisfaction. Such is the intellectual egocentrism that characterizes the earliest form of child thought.”

“The Moral Judgment of the Child translation by Marjorie Gabain from Archive.org”

“The discussion of the game of marbles seems to have led us into rather deep waters. But in the eyes of children the history of the game of marbles has quite as much importance as the history of religion or of forms of government. It Is a history, moreover, that is magnificently spontaneous; and it was therefore perhaps not entirely useless to seek to throw light on the child's judgment of moral value by a preliminary study of the social behaviour of children amongst themselves.”
