This is a landmark book. While applied analysis has been met with scepticism and inhibition in the psychopolitical sphere, this lag has been overcome, and more than made up for, by the leap forward contributed by the authors of this volume. The dynamics and psychopathology of large group behavior, including conflicts between nations, can now take their place in depth understanding alongside that of the individual. The result, expanding Freud's Group Psychology, is an inestimable advance in the reach of psychoanalysis.
