I have saved the best for last, like a rich dessert after a fine meal, although it appears as the introduction to the book. It is the tour de force by George Engel, writing with his usual perspicacity, clarity, and charm. In a gem of lucid prose, Engel asks, "How much longer must medicine's science be bound by a seventeenth century world view?" Besides its intensely human autobiographical content, the chapter is itself a treatise on the scientific method, with arguably more relevance to research than the book's appendix intended for that purpose. It is somewhat curious, and even amusing, that this major figure in the development of psychosomatic medicine has managed to write his entire chapter without once using the phrase (unless I missed it) "psychosomatic medicine."
