Full Idea
The Creator created not only the world, but also created possibility itself; therefore he should have created the possibility of a better world than this one.
Gist of Idea
The Creator created the possibilities for worlds, so should have made a better one than this possible

A Reaction
This is explicitly a response to Leibniz's claim that the Creator selected the best of all possible worlds from the available options. The Euthyphro Question hovers here: must the Creator accept what is possible (the platonic view), or create possibility?
