In a three-volume work that was never published, Nightingale presented her radical spiritual views, motivated by the desire to give those who had turned away from conventional religion an alternative to atheism. Michael D. Calabria and Janet A. Macrae provide the essence of Nightingale's spiritual philosophy by selecting and reorganizing her best-written treatments. "This book is an excellent resource for readers seeking to understand Florence Nightingale's thought and its place in the intellectual and philosophical history of nursing. The book provides fertile ground for study and reflection by those interested in a glimpse into the inner life of a complex and productive woman." --Nursing History Review
