Abstract

This is a well-written and interesting little book about a long and meandering letter drafted around 1067 by the great Christian reformer St. Peter Damian. It concerns the question of whether or not God can change the past. The letter is addressed to Desiderius, abbot of Monte Cassino and later Pope Victor III, but the object of Damian's concern apparently is certain dialecticians, possibly Berengar of Tours or Anselm of Besate, who put too great a stress on the capacity of reason to grasp truth independently of Scripture.
