Book excerpt: The book aims at reframing the discussion on the "public sphere," usually understood as the place where the public opinion is formed, through rational discussion. The aim of this book is to give an account of this rationality, and its serious shortcomings, examining the role of the media and the confusing of public roles and personal identity. It focuses in particular on the role of the theatrical and comical in the historical development of the public sphere, and in this manner reformulating definitions of common sense, personal identity, and culture.
