Sagesses et illusions de la philosophie

In this volume, Piaget reviews his early passions and presents his vision of philosophy. In particular, he argues that it allows problems to be defined and appropriate questions to be asked, but, given its discursive and non-experimental methodology, it can only offer tentative answers. On the other hand, science and genetic epistemology provide validated answers to these same problems through experimentation and logical-mathematical modelling. The book gave rise to a public debate between Piaget, psychologists Paul Fraisse and Yves Galifret and philosophers Francis Jeanson and Paul Ricoeur.
