So we must start from this dual nature of intelligence as something both biological and logical. - Jean Piaget

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 (the "social" element of the first months is only biologically social, so to speak, inside the individual, and therefore individualistic) 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."

As far as the game of marbles is concerned, there is therefore no contradiction between the egocentric practice of games and the mystical respect entertained for rules. This respect is the mark of a mentality fashioned, not by free cooperation between equals, but by adult constraint.
