When Sociological Impressionism was first published in 1981, it was the first comprehensive study on Simmel's social theory to appear in English since 1925. A pioneering work, it did much to bring about the rediscovery of Georg Simmel as one of the key sociologists of the twentieth century. David Frisby provides a provocative introduction to aspects of Simmel's social theory, seriously challenging many interpretations of his work, most notably the view that Simmel produced a formal sociology. By drawing on many little-known essays and pieces by Simmel and his contemporaries, the book locates him within the social and intellectual milieu in which he was working. This is a reissue of the second edition, published in 1992, which includes a new afterword confronting critical responses to the first edition. This is an important work, which will be of interest to students of sociology and social philosophy in Germany in the late nineteenth and early twentieth century.
