First, the freewill argument as made here
I was stating that God allows us to have free will and for the most part, the world that we live in is what we make of it. This is a very clear fact when we talk about murder, theft, assault, etc.
is insufficient to dispense of the problem of evil. One can always ask what happens to the free will of those assaulted as it is obvious it is annihilated in the process. And the bigger question is what stops god from redirecting our will to more acceptable goals unless of course our interlocutor is willing to accept that war, theft murder in some unknown way serves the purposes of god, that is, they are god’s will.
This next quote seems to be making the argument of the world/ earth as a place for learning or preparation. He writes
Perhaps the suffering caused by diseases is necessary to draw us together, and we simply make it worse by utilizing our ability to choose not to cooperate with one another, then we blame God because things seem to be too bad.
which one is forced to ask why did god not stop disease carrying organisms from boarding the ark?
And here we come to the Leibniz argument of the this is the best of all possible worlds
The secret is that things could be much, much worse.
an argument which is easily refuted by postulating a world where there is no measles.
This final paragraph does not help the case of our interlocutor
The middle class tend to compare themselves exclusively to the wealthy and ignore the poor while doing so. In this way, they focus on how things could be so much better than they are, rather than appreciating how far from homeless they are.
especially if he holds it as true that god is a benevolent provider. Then we don’t need destitution. In fact, it is possible to imagine a world arranged such that there is no destitution. The christians and muslims already imagine it and name it heaven where they have constant supply of milk and honey.
In summary, the argument that this is the best of all possible worlds is weak as an argument against the problem of evil or in trying to establish the being of a god.
