This is the first English translation of Dom Jean Mabillon's treatise that defends the propriety of study and research as an occupation for monks, and lays out a course of studies for young Benedictines training to be scholars. In the 1680s the strict Trappist reformer, Armand-Jean de Rance, published books condemning scholarship as a suitable occupation for monks. Mabillon belonged to the Maurists, a group of French Benedictines who were already launched on a 150-year odyssey of collecting, editing, and publishing critical editions of the church Fathers, the classics of early French literature and history, the annals of the Benedictine order from its beginnings, and critically vetted lives of Benedictine saints. Mabillon refuted Rance's claims, but transformed the debate by writing a masterful survey of authors and works with which monastic scholars should be familiar: pagan classics, the writings of early Christianity, and important publications of the 16th and 17th centuries on topics ranging from biblical scholarship to belles lettres to civil and canon law to books about books. Mabillon includes a "list of difficulties met with in reading the councils, the Fathers, and church history" that presents problems in a non-dogmatic, open-ended way. This edition includes a translator's introduction, suggestions for further reading on the monastic studies controversy, all Mabillon's marginal notes, a bibliography of all published works mentioned in the text, and an index.
