Introduction à l’épistémologie génétique

Vol. I. La pensée mathématique
Vol. II. La pensée physique
Vol. III. La pensée biologique, la pensée psychologique et la pensée sociologique

The three volumes of the Introduction to Genetic Epistemology lay the foundations of this new discipline, which links the psychogenesis of knowledge with the historical development of sciences. The validity of knowledge depends on its modes of construction, so Piaget assumes a continuity between the processes of construction of knowledge in children and in the sciences. The historical-critical, sociogenetic and psychogenetic methods make possible to understand the processes that are involved in the construction of notions and tools for knowledge.
