The Canadian physician and best-selling author of In the Realm of Hungry Ghosts is a brilliantly original thinker on addiction, trauma, parenting and the social context of human diseases and imbalances. Contrary to the assumptions of mainstream medicine, he asserts that most human ailments are not individual problems, but reflections of a person's relationship with the physical, emotional and social environment, from conception to death. Mind and body are not separate in real life, and thus health and illness in a person reflect social and economic realities more than personal predispositions. In other words, personal responsibility cannot be separated from societal responsibility and changing the world.
