Explain the main themes of theodicies in the Augustinian tradition

There are five main themes in Augustine's theodicy that would need to be explained. These themes would also need to be developed by theories from relevant Philosophers/Theologians such as Aquinas,Calvin and Leibniz as the question refers to "Augustinian tradition". The five main themes (in bold) are: 1.Evil as a privation of good - When God created the world "All that he had made was good " (Genesis 1) and therefore there was no evil or suffering. However Adam and Eve chose to commit an evil, implying that there must have been some evil to choose from. Augustine argues that evil could not have been created, as it is merely a privation of good and is not a "thing" in itself - it is a lack, therefore God could not have created evil. (Developed by Aquinas). 2.Free will as the cause of evil - humans and angels have free will, a God given gift, and decide whether to do right or wrong with it - God cannot interfere with the consequencences of our actions as that would infringe upon our free will, hence some of our actions will lead to evil and God is not to blame.(Developed by Calvin). 3. Predestination - God knew the fall would happen and sent Jesus as a way for us to redeem ourselves - but we must choose to accept Jesus as our saviour. However, when we don't, we turn away from goodness and bring evil into the world. This is called Soul deciding theory - as we decide through our actions whether we will go to hell or heaven. (Developed by Calvin) 4. Principle of plenitude - some people believe they have recieved less in life and therefore become resentful and bring evil into the world, this is becasue they cannot see the richness of creation; only God can see the goodness of the whole. (Developed by Leibniz). 5. Aesthetics principle - What appears evil to one person may be good for another - when a scorpion stings a human the human will see this as evil however the scorpion is just fullfilling it's purpose. (Developed by Leibniz)
