The Romans adaptation of Greek philosophy was illustrated by the Stoics and Epicureans. The Stoics held that humanity is determined by the fates of nature, while the Epicureans believed that happiness came from seeking pleasure and avoiding pain. Plato was revived by Plotinus and dominated Roman philosophy during the early years of Christianity. Both the missionary zeal of early Christians and the tranquility of Roman administration rapidly spread Christianity. The teachings of Jesus were bolstered by defenders, who gave Christianity form and content. St. Augustine successfully reinterpreted Platonic thought within Christian theology, and the consequent influence on psychology continued well beyond. With the fall of the Western empire, intellectual life came to a virtual halt, and only the monastic movement preserved remnants of Greek and Roman civilization. The papacy assumed a leading role in spiritual direction and civil administration. The power shift to the East saw the Byzantine Empire assume a distinctive Greek character. The rise of Islam threatened the survival of Christianity in the Middle East and in North Africa. But, at the same time, much of the Greek heritage of scholarship was preserved and extended in the great academic centers of medieval Islam.

“Community Rule” considers the reception of Classical ideas about systems and sustainability in Late Antique and early Christian thought with a particular focus on The Rule of St. Benedict. It also probes some of the Rule’s surprising modern legacies, including Scott and Helen Nearing’s homesteading experiments in Vermont and Maine and Pope Francis’s encyclical on climate change and inequality, Laudato Si’.
