Discussion Questions
Narration Prompt
Summarize the chapter's narrative arc, then identify the central tension and evaluate whether the author handles it honestly.
Discussion Questions
- The Professor's trilemma is structurally identical to the Liar/Lunatic/Lord argument Lewis deploys in Mere Christianity to defend the divinity of Christ. In both cases, Lewis uses process of elimination to force a conclusion that reason alone might not reach. Evaluate the trilemma as a form of reasoning: is it logically valid, or does it achieve its persuasive force by artificially constraining the range of possibilities? Does embedding it in a children's story expose its strengths or its weaknesses?
- The Professor's claim that nothing is more probable than other worlds represents a specific metaphysical position — not empiricism but something closer to what Lewis elsewhere calls supernaturalism, the conviction that the visible world does not exhaust reality. Evaluate whether the Professor's metaphysics is presented as a personal eccentricity, as the novel's operative worldview, or as Lewis's own philosophical commitment speaking through a character.
