This selection of lectures offers insights into the complexity of evil as a phe-nomenon that arises when an event or process appears outside its true context.As a result, something that is "good" initially may become "evil" because it occurs in the wrong place. Steiner tells us that this as an effect of Lucifer and Ahriman, spiritual beings who work as polar forces and hinder human evolution by opposing our appropriate development.Confronting these difficulties, however, ultimately furthers our spiritual development.
