The Jean Piaget Foundation for psychological and epistemological research was created in 1976 by Piaget with the aim of helping to develop these disciplines. The foundation has in effect supported over the years a certain number of scientific activities (scholarships for studying Piaget's papers, advanced research projects, organization of forums, etc.) such as publication of the latest research directed by or initiated by Piaget in the International Center for Genetic Epistemology.

In 2006 the foundation board of directors authorized the start-up of the Internet website, created with the primary aim of providing access to Swiss sage`s papers that are difficult to access and facilitating the evocation or discovery interviews, methods and conceptions that comprise psychological and epistemological genetics. In keeping with this extension that takes place progressively, the following items are or will be also placed at the disposition of the cibernauts: a well-equipped bibliography, a biography, audio and visual documents, introductory texts to the complete works or portions of same including reviews of published articles, etc.

06/01/2021The Jean Piaget Foundation for Psychological and Epistemological Research sadly announces the death of Professor Leslie Smith on 29 December 2020.
Les Smith, as he was known by his friends and colleagues, was Emeritus Professor at the University of Lancaster, United Kingdom. With a philosophical background, he made a major contribution to the diffusion and expansion of the constructivist approach of Jean Piaget and the School of Geneva. He was particularly interested in the problem of the emergence of necessary and atemporal knowledge, which he considered from an epistemological, logical and historical point of view. He was also deeply involved with the English translations of the works of Jean Piaget, highlighting the deontological necessity of translating them in accordance with the spirit of the text.
08/11/2020Jean Piaget Foundation is proud to announce that the selected works of Jean Piaget (about 60 to 70% of his writings, including articles) have been translated into Mandarin, under the direction of Prof. Li Qiwei with a team of one hundred translators, and have just been published in 10 volumes and 19 volumes with a preface by our president Marc Ratcliff.

15/11/2011We have placed on the Biography-Interview page of the Foundation’s website a recording in French (with a fixed image) of an interview with Piaget guided by G. Voyat (with assessment by B. Inhelder). This interview took place in February of 1980. The French text of the interview is available HERE (under 1980).

[…] l’évolution […] des notions spatiales, qui seule est décisive pour une épistémologie génétique, montre […] une dissociation graduelle entre les opérations spatiales d’un côté (donc les opérations constitutives de l’objet en général, relevant des coordinations opératoires du sujet, toujours mieux épurées et formalisées), et l’espace expérimental de l’autre (donc l’espace de l’objet physique, relevant des actions toujours plus différenciées par accommodation à la variété des objets et à la multiplicité de leurs qualités physiques, dont l’espace de l’expérience est solidaire).
