Book: Anselm St. Anselm of Canterbury (1033-1109) was one of the greatest Christian writers of medieval Europe. Best known as the inventor of the "ontological argument" for God's existence, his writings have been a major influence on western theology. He was also a noted spiritual writer. In this authoritative study, Dr. Evans explores the full range of Anselm's work, expertly placing both the thelogy and the devotional writings in context.
