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

Every psychological explanation comes sooner or later to lean either on biology or on logic (or on sociology, but this in turn leads to the same alternatives).

"Gustavo Solivellas dice: "Si un individuo es pasivo intelectualmente, no conseguirá ser libre moralmente" (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.
