Abstract
This paper tries to make clear why a European journal of developmental psychology makes sense. First it is explained that so-called European culture is a complicated matter: historically and culturally many fault lines are to be detected, from the borders of the Roman empire to the iron curtain. These fault lines separate different cultural areas within Europe.
Developmental thinking came into existence within the eighteenth century (Enlightenment), especially with the work of Rousseau, which offered the theoretical building blocks for Western education and for modern Piagetian developmental psychology. Empirical developmental research found its origins in Germany, especially in Jena, with the work of William Preyer. The Jena ideas were brought to the USA by Stanley Hall. And in the twentieth century the Rousseau–Piaget tradition was brought to the USA by John Flavell.
A European Society for Developmental Psychology and its flagship the European Journal of Developmental Psychology should devote itself to the study of the European roots of developmental psychology as well as contributing to European developmental psychology, which in an open, new Europe moves across the original fault lines.
