Possibility and Necessity

Volume 2

Author:

Jean Piaget
Translated by Helga Feider

Possibility and Necessity

“This book contains very important developments in Piaget’s theory, as in his treatment of knowledge he concentrated more and more on psychological-procedural processes of equilibration and less on logical-structural models. He considered the ‘opining up of infinite possibilities’ the central problem of any viable theory of knowledge in that it created a dialectical tension with the (almost contradictory) need for closure, proper to any biological system. Possibility and Necessity is an important empirical contribution to clarify equilibration, a concept which is perhaps the most important in his theory, and which he worked on and revised for fifty years.”

Hans Furth, The Catholic University of America
