Principle of Sufficient Reason
everything existing or occured has a sufficient explanation/cause for its existence/occurrence

there are contingent things
if both are true then there must be something not contingent that created them
Problem of Evil
theodicy: God and evil’s existence are probable

perfectibility
potential to increase perfection → Platonic ideas of goodness and godlikeness
change can be bad but a creature can not lose goodness it can be corrupt
