On the Psychology of Individual Differences

L. William Stern (1871 - 1938) was a German scholar whose hallmark contribution to psychology was, in his own view, a comprehensive system of thought he called 'critical personalism.' Within that system, Stern offered a philosophically sophisticated understanding of the psychological development of human personalities and, by extension, a vision of the dynamics of socio-ethically flourishing human communities.
