"I see psychiatric diagnoses as descriptions of psychological states that all ultimately come out of the person's experience of traumas and their responses to them.... [Regarding psychiatric patients] I feel that dual-brain psychology treats the person through an understanding of his or her psychology. And that, in my experience, always relates to his or her covert traumas, traumas that (for reasons not yet understood) usually relate to one cerebral hemisphere, either the left brain or the right brain."
