This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book examines the methodological ideas that underlie the Chicago tradition of qualitative research. It focuses on the writings of one representative of this tradition who has given particular attention to methodological issues: Herbert Blumer. The author warns the intending reader who is tempted to turn to the end of the book to discover his solution to Blumer's dilemma: none will be found there. In his view, there are no convincing solutions currently available. He discusses a number of ways in which a resolution might be achieved. The book moves us towards a solution by placing the issues with which it is concerned higher up the agenda, and by making more accessible some of the resources that might contribute to a solution.
