Final answer:
St. Augustine attributes the origin of evil to human fallibility following the disobedience in the Garden of Eden, maintaining that evil is the absence of good, and anchors this in a process of 'soul-making.' His Neo-Platonic view sees God's creation as inherently good, with evil serving a divine plan for a greater good.
Step-by-step explanation:
Introduction of Evil by Augustine
St. Augustine of Hippo, in grappling with the problem of evil, proposes that evil originated from the fall of humanity as depicted in the story of the Garden of Eden. This account places responsibility for the existence of evil on human beings, who were led astray by Satan. Augustine's approach solves the theological dilemma of reconciling an all-loving, all-good, and powerful God with the existence of evil by suggesting that evil is not a creation of God, but rather a privation of good. Humans, moving from bios (undeveloped life) to zoe (divine love and spiritual life), are engaged in 'soul-making,' which is a process allowed by God to achieve a greater good. Thus for Augustine, evil exists as a necessary part of a divine plan, which leads to a greater perfection in the whole, reflecting his Neo-Platonic influences.
In contrast, other perspectives such as that of Irenaeus view evil as a necessary condition for spiritual development, which encourages 'soul-making' through facing and overcoming evils. This view, however, introduces the concept that God could somehow be the author of evil, leading to a challenge regarding the all-good nature of God. Augustine's perspective differs in that it maintains God's complete goodness and omnipotence by reframing evil as the absence of good and asserting that all creation was inherently good because God created it. Augustine's ideas also delve into the realm of free will, offering an explanation that allows for human freedom within the divine foreknowledge and providence of God.
