As I was listening to FDR2659 and Stef mentioned again how the concept of a deity can be exploded by pointing out that such a thing could not simultaneously be both omniscient and omnipotent, I was struck by the parallel to Heisenberg's Uncertainty Principle, which states that we cannot know both the position and the momentum of a subatomic particle simultaneously. Voilà! I christen (pun intended) thee, Molyneux's Uncertainty Principle!
