'Until now no book has ever attempted to compare and contrast contributions on analytic field theory and at the same time to explore its clinical and technical implications. This volume is intended for the first time to link together many of these writings and to provide an initial wide-ranging survey of the subject - for it is our contention that a theory of the field in various of its loci can also be inhabited by different theories. A particular aim of this book is to present not only theoretical discussions of field theory, but also contributions on clinical work and technique. For this reason we have given preference to articles with a substantial clinical component which exemplify specific underlying technical theory. In the Babel of psychoanalytic languages, clinical practice is in our view the most effective way of comparing psychoanalytic models.' - From the Introduction.
