Each time one prematurely teaches a child something he could have discovered himself, that child is kept from inventing it and consequently from unde… - Jean Piaget

Knowing reality means constructing systems of transformations that correspond, more or less adequately, to reality. They are more or less isomorphic to transformations of reality. The transformational structures of which knowledge consists are not copies of the transformations in reality; they are simply possible isomorphic models among which experience can enable us to choose. Knowledge, then, is a system of transformations that become progressively adequate.

If mutual respect does derive from unilateral respect, it does so by opposition.

When the child imitates the rules practiced by his older companions he feels that he is submitting to an unalterable law, due, therefore, to his parents themselves. Thus the pressure exercised by older on younger children is assimilated here, as so often, to adult pressure. This action of the older children is still constraint, for cooperation can only arise between equals. Nor does the submission of the younger children to the rules of the older ones lead to any sort of cooperation in action; it simply produces a sort of mysticism, a diffused feeling of collective participation, which, as in the case of many mystics, fits in perfectly well with egocentrism. For we shall see eventually that cooperation between equals not only brings about a gradual change in the child's practical attitude, but that it also does away with the mystical feeling towards authority.
