Every acquisition of accommodation becomes material for assimilation, but assimilation always resists new accommodations. - Jean Piaget

Formal logic, or logistics, is simply the axiomatics of states of equilibrium of thought, and the positive science corresponding to this axiomatics is none other than the psychology of thought.

The notion of good, which generally speaking, appears later than the notion of pure duty, particularly in the case of the child, is perhaps the final conscious realization of something that is the primary condition of the moral life — the need for reciprocal affection. And since moral realism is, on the contrary, the result of constraint exercised by the adult on the child, it may perhaps be a secondary growth in comparison to the simple aspiration after good, while still remaining the first notion to be consciously realized when the child begins to reflect upon morality and to attempt formulation.
