For any possible pair of coexistent God-like omnipotent agents, one member of that pair could endeavor to actualize a different, equally good, world than the other member, even given their hypothesized necessary epistemic, moral, and aesthetic perfection.
So, for any possible pair of coexistent God-like omnipotent agents, it appears that one member of that pair could endeavor to actualize a different, equally good, world than the other member of that pair, even given their hypothesized necessary epistemic, moral, and aesthetic perfection. In the light of the reductio ad absurdum presented earlier, it appears to follow that such pairs are impossible.
