This collection of papers by Professor Rhett Diessner, psychologist at the Lewis-Clark State College of Lewiston, Idaho, and published in this volume, promotes the two Baha'i principles of "independent investigation" and "the harmony of science and religion." Psyche and Eros promotes the free and independent search after truth because it deals with psychology, a science that investigates and describes the inner reality of human beings, the soul. It promotes the principle of harmony between science and religion because it investigates each subect in the perspective of both the results of the scientific studies of modern specialists and the principles of the Baha'i Faith. The result is a book of spiritual psychology, which Diessner defines as "an emerging field within the new paradigm of applied spirituality", a "new area of study and research that focuses on the perspective that true human development and civilization is only possible when scientific research and technological advancement are harmonized with universal spiritual principles and ethical practices." A wonderful collection of articles that no student of psychology or spirituality should be without. It offers a glimpse into the future blending of scientific and spiritual understanding.
