This book reconstructs and compares the social theories of modernity of Georg Simmel and Walter Benjamin, two classic thinkers in German social thought. The author focuses on five main topics: the historical-sociological method through which they investigate modernity; how are the concepts of history and society possible; the consequences of modern metropolis on the construction of individual subjectivity; the aestheticization of everyday life caused by the expansion of commodity culture; and the female culture as a counter-power to the domination of masculine objective culture.
