JEAN PIAGET was born in Neuchatel, Switzerland, in 1896. He has been one of the most prolific academic writers of our time, beginning his career of publication at age ten, and continuing until his death in 1980 with an unabated flood of material. Brian Rotman notes:
Piaget's precocious B.A. and Ph.D. were earned from studies in the natural sciences. He quickly became one of the most prominent experts on mollusks, having published, by the age of twenty-one, over twenty-five papers based largely on his careful observations of mollusks in the lakes around Neuchatel. As Piaget has explained,2 56
these observations led to his general image of biological development as a process of adaptation to the environment.
