Few people have ever seen or heard of The Spirit of Simplicity: it has been hidden for almost seventy years after quietly being published by the Abbey of Gethsemani in 1948. Anonymously translated and annotated by a young monk named Thomas Merton, the book’s author–who also is not mentioned by name in the original edition–is Jean-Baptiste Chautard, the famous French Cistercian whose only other book, The Soul of the Apostolate, has been a favorite of modern saints and popes, including Pope Emeritus Benedict XVI. Every generation struggles with the question of simplicity. In the history of our faith, there have been no more eloquent voices calling us back to simplicity than the monks of the Cistercian Order, from Bernard of Clairvaux to Chautard to Merton–all of whom contribute to this powerful book. Merton surrounds Chautard’s text with his own remarks on simplicity, translations of classic texts by St. Bernard of Clairvaux, and commentary that allows readers to pursue the themes of simplicity in their own lives. “Only a very inadequate idea of exterior simplicity can be arrived at if we do not trace it back to its true source: interior simplicity. Without this, our resolution to practice exterior simplicity would be without light, without love …,” Chautard wrote at the beginning of the book. He is writing to his fellow Cistercians, but he might as well be speaking to twenty-first century Christians. He goes on to lay out the best disciplines that a monk–or anyone–might practice to find the elusive simplicity, with quotations from St. Benedict, St. Bernard, and other pillars of monastic life and spirituality. A dozen photographs of Cistercian architecture illustrate how principles of simplicity are incorporated into Cistercian daily life. In Part 2, Merton opens up the teachings of St. Bernard, a great mystic and doctor of the Church, offering excerpts from St. Bernard’s writings on the original simplicity in the Garden of Eden, the difficulty of intellectual simplicity, the simplicity of the will (obedience), and other kindred topics. Merton also offers personal reflections from the perspective of one who had recently exchanged an active life in pursuit of worldly things for the solitude of a monk.
