ABSTRACT
This book, like most books—and certainly like my books—began long before I imagined its conception. And even after it was conceived, it tugged insistently at my sleeve for quite some time, demanding my attention. Why it took so long to get to and to complete, I cannot be sure. Although lack of surety is certainly one of the foundations upon which the scaffolding of this book has been built. But because writing a book is such an ordeal, most authors ask themselves, at some point, “Why am I writing this?”
