This document discusses St. Augustine's views on the problem of evil and its explanation. It discusses how Augustine believed that evil was necessary for greater good to emerge, was a privation of goodness rather than positive, and that man rather than God was responsible for moral fall. It also discusses Augustine's view of original sin from Adam's disobedience and how only God's grace can redeem man. The document examines Augustine's philosophy that faith must precede reason and his ontological argument for God's existence.
