One of the most famous of the desert ascetics, Evagrius wrote of the eight "evil thoughts" of body and soul, such as sadness and anger, which oppose the "eight virtues," such as joy and patience. Bunge, an expert on this period, unravels the sophisticated psychology developed by Evagrius to carry on spiritual warfare. This 4th-century Desert Father writes for Christians everywhere: for those in modern deserts – the city – and for those subject to silent despair. This is a companion book to Dragon's Wine and Angel's Bread (SVS Press, 2009).
