““Kant argued that our intuition (i.e., sensibility) and understanding use a priori (i.e., independent of all experience) forms and categories, which are the condition of the possibility for experiencing objectivity. Piaget subscribed to the ordering and organizing function of the mind, but he believed that the forms and categories are not a priori but undergo development as a result of the subject's interaction with the world (OI, pp. 376–395).””
