Revisiting the Essential Indexical

In this book, renowned philosopher John Perry responds to criticisms of his influential writing on "the essential indexical." He begins by explaining the conclusions of his past articles. He then argues that many criticisms are based on confusions about the relation between the issues of opacity and cognitive significance, and other basic misunderstandings of his views. While dealing with criticisms, Perry makes a number of points about self-knowledge, the issue that motivated his original papers.
