How Do You Know Who You Are? Is a book for everyone. It traces, dissects and interprets the millennia-long quest for self-knowledge. Derek and Julia Parker have collaborated on a number of widely read books, and here, in twenty-four entertaining yet instructive sections, they use evidence ranging from the wisdom of the earliest civilizations to the latest psychological theories to take you along the many roads to self-discovery. Making extensive use of tests and charts, as well as many specially commissioned drawings and other illustrations, they help you to analyse your behavior, social standing and way of life. The result is a complete and fascinating guide to the world of your personality.
