Abstract
Although the theory of Jean Piaget is correctly characterized as genetic epistemology, its nature and scope remain unclear and controversial. An examination of Piaget's Introduction a l'epistemologie genetique indicates that Piaget relies heavily upon a model of comparative anatomy and, consequently, that genetic epistemology is about both the history of science and individual development. This biological model seems to be the basis for Piaget's view that the history of science can be seen as a (Kantian) history of scientific concepts whereas psychogenetic development is a history of these very same concepts on the individual level. Finally, although there are passages indicating a different interpretation of the scope of genetic epistemology, I give several reasons for preferring the more liberal interpretation
