 Some have found the reasoning from no-best-world to no-perfect-goodness persuasive, while drawing different morals from that entailment. Leibniz concludes that, because there is a God, there is a best world (“Essays on the Justice of God,” §8); Rowe and Wielenberg, by contrast, conclude that this entailment can serve as part of an argument against God’s existence (Rowe 2004, pp. 88–150; Wielenberg 2004). Others have been unmoved.
