In "A Grief Observed," C.S. Lewis reflects on the nature of questions posed to God, suggesting that many of them may be inherently nonsensical. He points out that some inquiries are so absurd that they cannot have meaningful answers, comparing them to asking how many hours are in a mile or if the color yellow is square or round.

Lewis argues that a significant portion of our profound theological and philosophical dilemmas might fall into this category of nonsense. By highlighting these examples, he emphasizes the limitations of human understanding and the complexity of divine matters, indicating that not all questions are worthy of pursuit.
