Knowledge in mind: Piaget’s epistemology COMMENTARY BY LESLIE SMITH
Kant addressed an epistemological problem: what legitimates anyone’s demarcation of objective knowledge from other kinds of human experiences? Piaget was captivated by this problem, but not by Kant’s answer, namely a fixed set of rational categories to be used in a priori judgments. In particular, he objected to the omission of an empirical check on the availability of these categories to all knowers (Piaget, 1922). His objection was extended by his peers’ collateral arguments, regarding the factual origin (genesis) of all knowledge (Baldwin, 1906), and the failure to reflect the development of knowledge in the history of science (Brunschwicg, 1922).
