As reflected in the 12 chapters of this book, the achievements of psychoanalysis during the first hundred years have been extraordinary. Each chapter is written by psychoanalysts strongly committed to a particular version of psychoanalysis theory and practice. As Robert Langs points out in his Foreword, the varying schools of psychoanalysis have. to a considerable extent, become relatively insular.' This book solves this problem by acting as a dynamic showcase for the enormous diversity, of explorations and thinking that characterize psychoanalysis today, a field to which some of the most brilliant and innovative thinkers of the late twentieth century have been drawn.
