Gabriel TardeGabriel Tarde
) French sociologist and social psychologist
who conceived Sociology
as based on small psychological
interactions among individuals (much as if it were Chemistry
), the fundamental forces being Imitation and Innovation
Among the concepts that Tarde initiated were the "group mind" (taken up and developed by Gustav Le Bon, and sometimes advanced to explain so-called herd behaviour), and economic psychology, where he anticipated a number of modern developments.
