What Dr McKenzie has uncovered is very unique to the field of psychiatry, and possibly represents one of the greatest breakthroughs, if not the greatest breakthrough, in the second half of the 20th Century.

Old theories of modern science literally melt away before the riveting and crystal clear logic that erases any thought of current hypotheses.

This book is rich in new ideas that are a further development of the enlightening, stimulative and provocative ideas described in his earlier book with Lance S. Wright, MD: Delayed Posttraumatic Stress Disorders from Infancy: The Two Trauma Mechanism. I have used this latter book in my courses at Georgetown University and I plan to continue to use the ideas of Dr. McKenzie in my classes. No one will regret reading this book.
