Can a mortal ask questions which God finds unanswerable? Quite easily, I should think. All nonsense questions are unanswerable. How many hours are there in a mile? Is yellow square or round? Probably half the questions we ask--half our great theological and metaphysical problems--are like that. [...] We cannot understand. The best is perhaps what we understand least.
~C.S. Lewis, A Grief Observed, (1961)
