'Michael Hyland, in [The] Origins of Health and Disease, creates a meta-theory of health and disease, a synthesis that incorporates the notions of mind, brain, body, and environment. This synthesis, based on a scientific theory, explains many of the mysteries of how humans heal. This is a book that will challenge the reader to move beyond conceptualizations of their discipline and should be read and understood by all physicians, psychologists, social workers, counselors - anyone involved in healing.'
