Bryce Carter, Ph.D. Therapy also relies upon language, and the survival instinct is embedded so deeply within our psyches that it predates our acquisition of language. Medication only is meant to alleviate the symptoms of depression. It cannot reach that deep well of life force that exists within us all. Now, as a good psychologist I have to say that there has been enough research done on this project to recommend this book out of hand. But I am sure that this will strike an intuitive cord with many people, and I encourage you to contact RMCAT and Peyton Quinn and read this book very carefully. It is my opinion that regularly exercising one survival instinct inoculates one against depression. the healthy exercise of assertiveness and non-destructive aggression helps to activate our psychological immune system.
