Jean Piaget was one of the great thinkers of the twentieth century. His influence on developmental psychology, education and epistemology has been enormous. This text undertakes a reconstruction of the contexts and intellectual development of Piaget's numerous texts in the wide-ranging fields of biology, philosophy, psychoanalysis, child psychology, social psychology, theology, logic, epistemology and education. Richard Kohler reconstructs the often overlooked theological basis of Piaget's theories and analyses the influence this had upon the various areas of his research and reflections, particularly in relation to education.
