There are no more such things as societies qua beings than there are isolated individuals. There are only relations .... and the combinations formed by them, always incomplete, cannot be taken as permanent substances (Piaget, 1932, p. 360)... there is no longer any need to choose between the primacy of the social or that of the intellect: collective intellect is the social equilibrium resulting from the interplay of the operations that enter into all cooperation (Piaget, 1970, p. 114)
