The first book in English devoted to the great French author Henry Corbin, Tom Cheetham’s The World Turned Inside Out is an excellent introduction to and survey of Corbin’s work and thought. Corbin is unique among 20th century scholars of Islam in his ability to imaginatively enter the world of the Sufi gnostics and to apply their insights to the modern World. Cheetham’s book provides us with a bracing and stimulating overview of this seminal author’s work and its implications: this is a book for all who suspect that, to paraphrase Plato, there is more to life than that which can be grasped in one’s hands. - Arthus Versluis, editor of Esoterica and author of The Esoteric Origins of the American Renaissance .
