Rediscovering Gabriel Tarde∗

Gabriel Tarde (l843–1904) is thought to have “lost” his debates with Durkheim by insisting that sociology ought to occupy itself with observable interpersonal processes. Given contemporary interest in such processes—much abetted by the computer—Tarde's reputation is being rehabilitated. CitationTerry Clark (1969) was first to notice that Tarde (1898) had anticipated Lazarzfeld's two-step flow of communication. Tarde's work has bearing on social networks, interpersonal influence, diffusion of innovation, and the aggregation of public opinion.
