Life of Pi
I heard the words, "Is someone there?"
It's astonishing what you hear when you're alone in the blackness of your dying mind. A sound without shape or colour sounds strange. To be blind is to hear otherwise.
The words came again, "Is someone there?"
I concluded that I had gone mad. Sad but true. Misery loves company, and madness calls it forth. (2.90.11-14)
I was getting used to the mental delusion. To make it last I refrained from putting a strain on it; when the lifeboat nudged the island, I did not move, only continued to dream. The fabric of the island seemed to be an intricate, tightly webbed mass of tube-shaped seaweed, in diameter a little thicker than two fingers. What a fanciful island, I thought. (2.92.9)
[Mr. Okamoto:] "I'm sorry to say it so bluntly, we don't mean to hurt your feelings, but you don't really expect us to believe you, do you? Carnivorous trees? A fish-eating algae that produces fresh water? Tree-dwelling aquatic rodents? These things don't exist."
[Pi:] "Only because you've never seen them."
[Mr. Okamoto:] "That's right. We believe what we see." (3.99.47-9)
