Fox, a controversial Dominican priest and author of Creation Spirituality ( LJ 5/1/91), offers this compendium of the teachings of St. Thomas Aquinas. Through a series of four ``conversations,'' he translates the context of Aquinas's spiritual theology into popular language. The dialogs center on the four paths within creation spirituality: Via Positiva (awe and wonderment), Via Negativa (silence and darkness), Via Creativa (imagination and creativity), and Via Transformativa (compassion). Fox uses the writings of Aquinas to provide a dialog that brings forth a positive guide to spiritual growth. Instead of the ``fire and brimstone'' approach to salvation, the reader is exposed to the path of cosmological spirituality. Recommended for large public and academic libraries.-- L.
