Logical positivists have never taken psychology into account in their epistemology, but they affirm that logical beings and mathematical beings are nothing but linguistic structures.
Knowing reality means constructing systems of transformations that correspond, more or less adequately, to reality.
The child is a realist in every domain of thought, and it is therefore natural that in the moral sphere he should lay more stress on the external, tangible element than on the hidden motive.
The essential functions of the mind consist in understanding and in inventing, in other words, in building up structures by structuring reality.

Scientific knowledge is in perpetual evolution; it finds itself changed from one day to the next.

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.
