Dr. Paul Brand, who grew up son of English missionaries to South India, achieved world renown for his research on leprosy and related research on the dynamics of pain. This book, one of several of his reflections on physiology, combines autobiography, stories of research, and reflections on pain and pain management. The three topics roughly correspond to three discrete sections.

It opens with a story of the early death of a child with a rare neurological dysfunction that made her insensitive to pain. Brand's long work with victims of leprosy in India and then in Carville, Louisiana, gave him wide exposure to the consequences of life without adequate pain. Having spent 27 years in India, 25 years in England, and 27 years in the U.S. before writing this retrospective, many of his reflections include observations about cultural variables in perception of pain, how pain is communicated and managed, and how people deal philosophically with the problem of pain.
