The article argues for the relevance of rediscovering Wittgenstein in social theory with particular focus on his philosophical method. The article is divided into three parts. Part I gives a brief overview of Wittgenstein’s role in the coming of age of the influential 1980s generation of European social theory. Parts II and III discuss Wittgenstein’s method and its significance for social theory. In Wittgenstein’s late philosophy, there are deep and unique insights to be gained about doing theoretical research. These insights can be extended to the social sciences. The article argues that the tradition of social theory can benefit from being linked to Wittgenstein’s method which suggests a way of theorizing on the basis of detailed case-knowledge; that it can profit from bringing this method into an explicit relation to existing approaches, styles and tools in social theory. Despite its sketchy and unfinished character, Wittgenstein’s case study method can be a guide for a way of bridging the widening gap between theoretical and empirical forms of research that can be observed in the social sciences today.
