Augustine formulates the privation theory of evil: all things that exist are good insofar as they exist; corruption is always a loss of some good; evil is therefore not a substance but a privation of good, and God created all substances good, unequal in degree yet together ‘very good’.

By Augustin d'Hippone, from Les Confessions

Key Arguments

  • He begins from the goodness of corruptible things: "It was obvious to me that things which are liable to corruption are good."
  • He argues that if they were supreme goods, they would be incorruptible, and if there were no good in them, they could not be corrupted: "If they were the supreme goods, or if they were not good at all, they could not be corrupted. For if they were supreme goods, they would be incorruptible. If there were no good in them, there would be nothing capable of being corrupted."
  • Corruption is defined as harmful diminishment of good: "Corruption does harm and unless it diminishes the good, no harm would be done. Therefore either corruption does not harm, which cannot be the case, or (which is wholly certain) all things that are corrupted suffer privation of some good."
  • Total loss of good would imply non‑existence: "If they were to be deprived of all good, they would not exist at all."
  • He rejects the absurdity that losing all good could improve things: "What could be more absurd than to say that by losing all good, things are made better? So then, if they are deprived of all good, they will be nothing at all. Therefore as long as they exist, they are good."
  • From this he infers that evil cannot be a substance, since every substance as such is good: "Accordingly, whatever things exist are good, and the evil into whose origins I was inquiring is not a substance, for if it were a substance, it would be good."
  • He notes that even a corruptible substance would have to be good in order to be corruptible: "Either it would be an incorruptible substance, a great good indeed, or a corruptible substance, which could be corrupted only if it were good."
  • He concludes that God made all substances, all of them good, though unequal, and that taken together they are ‘very good’: "you made all things good, and there are absolutely no substances which you did not make. As you did not make all things equal, all things are good in the sense that taken individually they are good, and all things taken together are very good. For our God has made ‘all things very good’ (Gen.1: 31)."

But in the parts of the universe, there are certain elements which are thought evil because of a conflict of interest.
