Strengths of Augustine's theodicy
This theodicy's main strength is that it never suggests that God tolerates evil or wants to have a world with evil in it - God has nothing to do with it - therefore humans' misuse of free will is responsible
Christian Scientists - religious group, founded by Mary Baker Eddy - agree with the idea of the non-reality of evil
HOWEVER, this is not a satisfactory explanation because even if evil is an illusion, it is real enough and has real symptoms - eg the death of terminally ill people
