Keith DeRose discusses Leibniz and the Problem of Evil. After distancing himself from Leibniz's requirement that God wouldn't create a world that isn't the best of all possible worlds, Keith indicates agreement with Leibniz on one matter. He thinks the best theistic response to the problem of evil will have to involve something like the aesthetic analogy that a whole picture can be improved because part of it is, in itself, less good than it could have been.
Aquinas says something like this, but his view of divine providence, while not agreed by all scholars to amount to theological determinism, does involve a strong enough view of providence that God in creating had an awareness of the entire plan of the history of creation, including what every free being would do. Leibniz, as a theological determinist of some sort, very much needs to say something like this. Keith mentions that Marilyn Adams also says something similar, but as far as I can tell her response to the problem of evil is intended to be fully consistent with compatibilism about free will and determinism. On the other hand, Keith is a libertarian. What I'm not clear on is why a libertarian should think the best response to the problem of evil would require saying something along these lines. Any thoughts?
