"Based on the reading of the only twelfth-century manuscript of the Enigma extant, Charleville MS. 114, and an examination of the fifteenth-century manuscript Uppsala C. 79." Revision of the editor's thesis, Catholic University of America, 1971, presented under title: The enigma fidei of William of Saint Thierry, a translation and commentary. Bibliography: p. 119-120.

William of Saint Thierry left all things in his search for God. He left his home in Liage (modern Belgium) to study in France. He left the schools to enter benedictine monastic life at Rheims. And late in his life he left the Benedictines to enter the more austere, recently founded cistercian abbey of Signy in the Ardennes forest. What he did not leave was his keen intellect and his vehement love of Truth.
