The Problem of EvilThe Problem of EvilLeibniz’s ExplanationLeibniz’s Explanation
To appreciate Leibniz’s assertion that this is To appreciate Leibniz’s assertion that this is the “best of all possible worlds,” we must the “best of all possible worlds,” we must explore:explore: What can an “all-powerful” God really do? What What can an “all-powerful” God really do? What
