Immanuel Velikovsky called this book the "fulfillment of his oath of Hippocrates--to serve humanity." In this book, he returns to his roots as a psychologist and psychoanalytical therapist, yet not with a single person as his patient but with humanity as a whole. After an extremely revealing overview of the foundations of the various psychoanalytical systems he makes the step into crowd psychology and reopens the case of Worlds in Collision from a totally different point of view: as a psychoanalytical case study. This way he shows that the blatant reactions to his theories (which are still going on today) have not been surprising but are actually inevitable from a psychological perspective--which equally holds for those who have defined our view of the world. At the same time he is able to reclassify the theories of Siegmund Freud and of C. G. Jung by finding a common basis for them. A journey through history, religion, mythology and art shows the overall range of the collective trauma and gives us--the patients--a message of extraordinary urgency and importance for the future.
